Re: Is sqlplus too slow to unload data?

Hi,
Our application uses sqlplus + sqlloader to transfer data between

files(1G), which is far too slow. In the application, the query looks
like the following. All those 3,4,5 are for sqlldr format.
How about using Perl?
Below is a script I just used to unload a table. Not very big, but this
is just from one of my test databases at home on a Linux box.
It unloaded about 12,000 rows in less than 2 seconds. This include
writing them to a file. This script creates a file of TABLENAME.dmp.

Re: Curious question about flushing the Pool
Tim, I've had opportunity to tune the database in an attempt to fix a poorly ( very ) designed application. This app may well benefit from CURSOR_SHARING=FORCE, but that would negate the use of histograms on one table that makes good use of them. That parameter may also have an effect on the optimizer_index_caching and optimizer_index_cost_adj parms as well, though I'm not sure about that one, and I'm too lazy to go look for it right now. It will definitely negate histogram usage though. Jared PS. This is absolutely the worst designed app I have ever had the misfortune to work with. I seem to draw these somehow.

Re: Curious question about flushing the Pool
I'll second that suggestion! To extend the analogy, how about a recycle pool for them? (So they don't fragment or otherwise clutter up the keep pool.) How about adaptive auto-pin in the keep pool based on execution frequency? (Never mind... Probably not really necessary. I'd settle for the LRU bias.)

Re: Curious question about flushing the Pool
Comments? Corrections? Rants? I'll go for rant... I've had long and painful experience with a few pathological applications. One in particular contained hundreds of sets of common SQL statements - varying only in the literal values. Many were executed hundreds of thousands or even millions of times every day. (e.g. What could have been a few hundred distinct statements with bind variables was instead tens or hundreds of millions of distinct statements in the course of a day.) None of these applications ran on anything later than Oracle 8.1.7.1 - some on 7.3.x. On the vast majority of the 8i systems, there was some bug/quirk that prevented CURSOR_SHARING=FORCE. (For example, one such bug/quirk was that if the value for the first variable in a bind list was a null, the application process puked and either hung or died. I don't now remember the specific color, chunksize, ORA-x, or bug number though.) The typical symptom was a gradual degradation of overall performance as the shared pool filled up. When it slowed to a crawl, the only remedy was to flush the shared pool - which resulted temporarily in a much more dramatic performance hit. (Would you like that adhesive tape pulled off your hairy chest a little at a time or in one quick heart-rending yank?) Then everything ran fine until we came full-circle again on the roller-coaster ride. We created a scheduled job to flush the shared pool and tuned the frequency with which it ran! This continued for at least 2 1/2 years (until I left). I hear that it is still the main performance issue with this particular ultra-critical multi-million dollar system (loaded E10K, large EMC Sym, ...). I showed the outsourcing consultants that designed and wrote this atrocity the wait analysis - which they adamantly insisted was NOT caused by their code. (Tuning is the DBA's responsibility - and our management bought it). My most convincing argument was routinely dumping a join of v$SQLAREA and v$SQLTEXT sorted by SQL_TEXT into a file. Actually seeing 60,000+ copies of the same statement differing only in literal values, followed by 23,000 of another, etc. eventually convinced management that it might actually be a problem. (This isn't an argument against using the wait interface, but in this case it was unnecessary - the problem was quite obvious). Just as I fled the company, one of the people who took over this system came up with a simple solution (encouraged by Oracle support and several very popular tuning books) - he raised the shared pool size to almost a gigabyte - in spite of my admonitions. Oddly enough, that made it MUCH worse! ;-) In this case, the flushing solution was just barely survival. And, obviously, it did nothing to avoid the wildly excessive parsing. In other words, I agree - flushing the shared pool is curing symptoms, not the disease.

Hi, What should be the basis of selecting a type of server machine? Single processor, two processor, four processor How many years down the road should one plan for? In web deployment, the web server will have connection(s) with data server and can be configured for connection sharing. What role the number of connections between data and web server plays in server selection? Please do give some solid guidelines. TIA!

RE: Any scripts to check the health of the database
This is something that I am looking for a way to check on an 8.1.7 database running on NT without me physically having to login myself. Is there some automated way to do this, that maybe can send an email to a computer operator?? Thanks, Dave -Original Message- Sent: Wednesday, April 24, 2002 4:13 PM To: Multiple recipients of list ORACLE-L Personally, I think that many folks go a bit overboard when it comes to checking the health of a database. These are the things I like to check for: * is the database up? this is the most important tech check * status of jobs in DBA_JOBS * space issues. Will a table be able to extend N times without error? * are the users happy? This is actually more important than any of the technical issues. There's a lot of other things you can check, but personnaly, I quit checking them long ago. I do log a few things from the database, and periodically store the explain plans for SQLin the cache for troubleshooting later the things go awry. This is really not part of a periodic health check though, this is a whole different matter. One thing to keep in mind: Rolling your own helps you to understand what's being monitored. :) Jared Praveen Sahni [EMAIL PROTECTED] Sent by: [EMAIL PROTECTED] 04/24/2002 12:24 PM Please respond to ORACLE-L To: Multiple recipients of list ORACLE-L [EMAIL PROTECTED] cc: Subject:Any scripts to check the health of the database Hi All, I need to write a report on the health of a database.

However, I would suggest that tracking 'normal' delta values of 'cache buffer chain' gets, misses, spins and sleeps from V$SYSTEM_EVENT/V$LATCH, as well as deltas of 'table scan rows gotten' vs 'table fetch by rowid' would be a better 'ratio' than the CHR which will only serve to feed a myth. The former would give you some indication of LIO (and the stress it causes on the system) and the latter will indicate raw requirements that were met but were the ones that drove PIO As for me, I detect changes in the following SQL and page out to an on-call DBA when some set limits are exceeded: select event, count(*) from v$session_wait group by event; This does show the 'current' bottleneck and I still remain true to the calling of OWI!!

Can't Break In and Securing iAS on NT
I am reading through O'Reilly's Apache: The Definitive Guide, 1999. On page 42 it says: In plain English, this means, once again, that Win32 is not an adequate platform for running a Web server that has any need for security. Has anyone been able to get info out of MetaLink on how to secure iAS on NT? Do you have any info on how to secure iAS on NT? I was told last year to install iAS on NT and this year I have been told to secure the Oracle servers. If you have any info, SANS would probably like to see it too, they are putting together an Oracle security guide. I like Oracle, in my opinion it's better than anything else out there right now. But I have been told to secure the Oracle servers and so far I appear to have hit a brick wall with the MetaLink helpdesk people, they keep asking me if I have specific concerns. I asked them to tell me if the local administrator account is the right one to use for installing Oracle software on NT, one technical analyst quoted installation notes saying that a new account should be created and placed in the local administrators group; another told me that the local administrator account is fine; the third one hard closed my TAR without answering my question. He figured that since I had asked the same question for iAS, OEM and the rdbms, he didn't need to answer my question.

Once the Shared SQL Area has filled, it becomes necessary for the RDBMS must find an entry to age-out of the cache instead of just simply locating the next empty slot. So, frequent usage of the FLUSH SHARED_POOL command continually keeps the Shared SQL Area on a less-contentious always filling basis, rather than the very-contentious gotta-pitch-one-to-make-room-for-another basis.

Anyway, if this is the problem they are facing, then a script to periodically (i.e. 5 mins? 30 mins? 60 mins?) FLUSH SHARED_POOL may be the only way to survive.

Re: Curious question about flushing the Pool
Minor correction, cursor_sharing did work in versions under 8.1.7.3 (I used it in 8.1.6) but there was a bug relating to very specific usage. I never encountered it, I know you can look up the details of the bug on Metalink. Having said that, I used cursor_sharing=force instead of flushing the shared pool because it does almost entirely eliminate the out of memory error, while flushing, if you misset the timing, doesn't. We had programmers who did not want to use bind variables (Java prepared statements) and so, for an OLTP system where they were looking up registration information, we ended up with each SQL statement, differing only by the constant value being looked up, in the shared pool. I lost the fight to have the code fixed, and so turned on cursor_sharing.

Once the Shared SQL Area has filled, it becomes necessary for the RDBMS must find an entry to age-out of the cache instead of just simply locating the next empty slot. So, frequent usage of the FLUSH SHARED_POOL command continually keeps the Shared SQL Area on a less-contentious always filling basis, rather than the very-contentious gotta-pitch-one-to-make-room-for-another basis. SQL is not being re-used, but it's not being re-used anyway -- using FLUSH SHARED_POOL has no impact on that. At least, that's my simple-minded way of looking at it... Anyway, if this is the problem they are facing, then a script to periodically (i.e. 5 mins? 30 mins? 60 mins?) FLUSH SHARED_POOL may be the only way to survive. However, if there is another alternative, then it might be worthwhile to attempt to talk them off the precipice... Comments? Corrections?

So you are famous, even if you were not present :) And yes, without seeming to migrate to the CHR camp, there is some merit in what you are saying. However, I would suggest that tracking 'normal' delta values of 'cache buffer chain' gets, misses, spins and sleeps from V$SYSTEM_EVENT/V$LATCH, as well as deltas of 'table scan rows gotten' vs 'table fetch by rowid' would be a better 'ratio' than the CHR which will only serve to feed a myth. The former would give you some indication of LIO (and the stress it causes on the system) and the latter will indicate raw requirements that were met but were the ones that drove PIO As for me, I detect changes in the following SQL and page out to an on-call DBA when some set limits are exceeded: select event, count(*) from v$session_wait group by event; This does show the 'current' bottleneck and I still remain true to the calling of OWI!!

OLAP Financial Function Calculators for Oracle 9i.
Hi I would like to know if the Oracle Express feature of Financial Function Calculators are available with Oracle enterprise Edition 9.0.1.0.0.

Re: good value for optimizer_index_cost_adj
My 1/2 cents on this... Another way of thinking of scattered -vs- sequential reads is that a scattered read is used when you know up front that you want to read several blocks and know which blocks they are. You can then use a vectored read to do this or farm them all out in parallel using asynchronous read. Sequential reads implies that you need the result of each block before you can determine the next block to read. Therefore you do single block I/O. Bill --- Jonathan Lewis [EMAIL PROTECTED] wrote: Well, Tim did say he was making a long story short. scattered reads = multiblock reads which are typically associated with tablescans, but can be index fast full scans. sequential reads = single block reads which are typically associated with index block reads, table blocks accessed as a consequence of index block reads, but can be one-off blocks in table scans and index fast full scans due to the existence of previously buffered blocks or tail-end blocks on extents.

No Rows Deadlock and PCTFREE, INITRANS on 8.1.7.2
We are testing an upgrade of our warehouse from 8.0.4 to 8.1.7.2. While testing our nightly load job that runs in two simultaneous streams (ascending and descending), we have been getting deadlock errors. The trace file shows the the rows waited on are no rows. In response to a TAR I opened with Oracle, Oracle responded that the application needs to be rewritten so that there is only a single stream. However our developers aren't inclined to do so because our nightly window isn't long enough for a single job and because this application worked fine as is on 8.0.4. Our developers have discovered an old article (perhaps from 7.3.4 times) by Roger Snowdent The Deadly Embrace (Oracle Locking Strategies) www.dbdomain.com/120197.htm that indicates this deadlock error with no rows is an indication of an insidious table. The article states that the the INITRANS and PCTFREE parameters may be set too low for the table in use. Has anyone encountered this deadlock with norows indicated error before? If yes, how did you resolve it? In our current 8.0.4 datawarehouse database, this partitioned table has PCTFREE of 10 and INI_TRANS of 1. The block size is 8k, we are using Sun Solaris 2.6 and Veritas Volume Manager. As I said, we are preparing to upgrade this to 8.1.7. What would be an appropriate setting for PCTFREE and INI_TRANS for this large warehouse partitioned table in these circumstances? What are our options if we want to change the PCTFREE and INI_TRANS for new data that gets loaded? Can we change PCTFREE and INI_TRANS and then just keep loading more data into an existing partition? Can we change these values in new partitions and leave them the same in existing partitions? What would be the drawbacks of having some partitions with one value for these storage parameters and other partitions with different values? Also, the developers want to know if there is any utility that could be run to determine whether other tables might be susceptible to this deadlock condition. Something like dbverify or analyze with some validation option? Thanks in advance for your feedback.

Without the availability of the CURSOR_SHARING=FORCE functionality, the Shared SQL Area is simply at the mercy of the application. As I visualize it (and I could be very wrong!), there is little contention as long as the Shared SQL Area is *filling up*. Once it is *full*, however, is when contention starts. Once the Shared SQL Area has filled, it becomes necessary for the RDBMS must find an entry to age-out of the cache instead of just simply locating the next empty slot.

Re: Can't Break In and Securing iAS on NT
Sounds like the only way to secure iAS on NT is not to put it on NT. You might try LINUX. It would at least let you use your existing hardware. And, it's free or relatively cheap depending on distro.

On page 42 it says: In plain English, this means, once again, that Win32 is not an adequate platform for running a Web server that has any need for security. Has anyone been able to get info out of MetaLink on how to secure iAS on NT? Do you have any info on how to secure iAS on NT? I was told last year to install iAS on NT and this year I have been told to secure the Oracle servers. If you have any info, SANS would probably like to see it too, they are putting together an Oracle security guide. I like Oracle, in my opinion it's better than anything else out there right now. But I have been told to secure the Oracle servers and so far I appear to have hit a brick wall with the MetaLink helpdesk people, they keep asking me if I have specific concerns. I asked them to tell me if the local administrator account is the right one to use for installing Oracle software on NT, one technical analyst quoted installation notes saying that a new account should be created and placed in the local administrators group; another told me that the local administrator account is fine; the third one hard closed my TAR without answering my question.

So you are famous, even if you were not present :) And yes, without seeming to migrate to the CHR camp, there is some merit in what you are saying. However, I would suggest that tracking 'normal' delta values of 'cache buffer chain' gets, misses, spins and sleeps from V$SYSTEM_EVENT/V$LATCH, as well as deltas of 'table scan rows gotten' vs 'table fetch by rowid' would be a better 'ratio' than the CHR which will only serve to feed a myth. The former would give you some indication of LIO (and the stress it causes on the system) and the latter will indicate raw requirements that were met but were the ones that drove PIO As for me, I detect changes in the following SQL and page out to an on-call DBA when some set limits are exceeded: select event, count(*) from v$session_wait group by event; This does show the 'current' bottleneck and I still remain true to the calling of OWI!!

Title: RE: Oracle ODBC On Windows95 (Don't ask) :) Are you just trying to setup an ODBC conenction? In Control Panel, you should see an icon for an ODBC manager where you can add dns entries . You STILL will need to install Oracle client. Use the db alias name for the Service name in the ODBC setup. On 95, I believe that there are 2 sets of Oracle ODBC drivers, one put out by Oracle and the other by Microsoft. funny but I remember we had to use the Microsoft drivers because we had problems with the Oracle ones.

RE: UNIX Courses
Simon, Get hold of a cruddy Intel box. Install Suse 7.0 Linux and Oracle 8.1.7. Configure your environment so that your default shell is sh, bsh, or ksh. Play with it until it breaks. OReilly's Learning Unix, Unix in a Nutshell and Learning the Korn Shell can help with everything you need to know. Don Burleson's Unix for Oracle DBAs may help too, I've really only glanced through it but it looks useful for starters. As far as classroom courses go, I've never attended one that I thought was better than teaching myself. Having said that, if someone else is paying follow Oracle recommended course path (but build the test box too).

What block size are you using for your new 9i data warehouse?
We are building a new version 9.0.1 data warehouse on Sun Solaris 2.6 migrating to Solaris 2.8. We will be using striped disk that is striped using Veritas Volume Manager on EMC disk. The datawarehouse will be about 200 Gig. It will be written to throughout the day. To this point, almost all of our databases have been created with an 8k block size. i'm not sure if that blocksize is optimal anymore. With 9i, what block sizes are people using in the field nowadays for data warehouses? Also, if you use striped disk, what stripe size are you using and why? Thanks for weighing in on this topic.

RE: Curious question about flushing the Pool
I lost the fight to have the code fixed, and so turned on cursor_sharing. Worked like a charm Been there, done that... but now I feel better knowing that a tenacious goddess of the DBA battlefields also lost this fight. :-) It's a tough fight when embedded SQL is scattered all over the place and development is more concerned with coding the next feature set on Internet time. Apart from the tons of embedded SQL, we have a dynamic SQL generator function in our code which creates SQL with literals based on states or values in webpage check boxes, radio buttons, dropdownlists, text boxes, etc. Since this is a central, oft-used part of the app I'm hoping to get duhvelopment to use bind variables in it but it's going to be an uphill battle. Just the normal frustration in the on-going DBA/Duhveloper battle. Sigh... Steve Orr Bozeman, MONTANA! -Original Message- Sent: Thursday, April 25, 2002 6:58 AM To: Multiple recipients of list ORACLE-L Importance: High Minor correction, cursor_sharing did work in versions under 8.1.7.3 (I used it in 8.1.6) but there was a bug relating to very specific usage. I never encountered it, I know you can look up the details of the bug on Metalink. Having said that, I used cursor_sharing=force instead of flushing the shared pool because it does almost entirely eliminate the out of memory error, while flushing, if you misset the timing, doesn't. We had programmers who did not want to use bind variables (Java prepared statements) and so, for an OLTP system where they were looking up registration information, we ended up with each SQL statement, differing only by the constant value being looked up, in the shared pool.

In 8i you had to put the database in managed recovery mode(or you manually did recovery) on the standby db. I hope no one was doing manual recovery every time a archive log was shipped across. :) Now with 9i dataguard, the standby database can be built either: 1. manually just like you did in 8i or2. automagically with OEM Dataguard Wizard(crazy wizards foreverything anymore). I personally couldnt get the wizard to work with 9.0.1.0. Does it work now?, I'm not sure as I've not tested it as of recent. The manual method works just fine. Ok so you need to create a standby database, we're not going to cover that here, why?, Mostly cause we're only going to cover the new aspects, you all can read the docs as well as I can to build the db. On to the new stuff: Your standby database in 8i was only in what we call "delayed" protection mode, which means there is a delay from the time the logs are completed on the primary database before they are appliedto the standby database. Now with 9i, you have 3 other modes: Guaranteed protection: indicates that primary database modifications are available to the standby database, up to the last committed transaction. The standby database cannot diverge from the primary database at all, and no data can be lost. If a standby database is unavailable, processing automatically halts on the primary database as well. Instant Protection: With instant protection, the standby database may temporarily diverge from the primary database, but upon failover to the standby database, the databases can be synchronized, and no data will be lost. Rapid Protection: With rapid protection, the log writer process transmits redo logs to the standby sites. Use this mode when availability and performance on the primary database are more important than the risk of losing a small amount of data. An important note is that in Guaranteed and Instant protection mode that the logs are written in SYNCHRONOUS mode to the standby site. Rapid and Delayed mode are ASYNC writes. So this begs to ask what is the difference between Guaranteed and Instant? Well in Guaranteed mode the logs are applied and there is no data divergence from the primary and standby db. Whereas Instant mode there can be data divergence but upon failover there will beNO data loss. So since we wont have data loss, there is a new way to "failover" to a standby database, called switchover. You can literally be able to switch to a standby database and switchback to the original primary WITHOUT having to reinstantiate(ie: rebuild) the primary. A very nice feature, this gives you the capability to do rolling upgrade of OS -NOTICE, NOT ORACLE BINARIES YET, ONLY THE OS. In 8i you could only do a failover(which required rebuilding the primary), you can still do a failover in 9i if you've lost the primary db in some disaster like the computer room caught on fire. Now for the automated part: There is the dataguard manager/broker, it can be run from command line($ORACLE_HOME/bin/dgmgrl) as well as from OEM. This gives you the luxury of oracle doing all the work to maintain consistency between the primary and standby database.

RE: No Rows Deadlock and PCTFREE, INITRANS on 8.1.7.2
You mention a partitioned table. Not an IOT I hope? Because SELECTs can cause deadlocks on an IOT if you partition it in the process (deadlock on DDL, as opposed to DML, locks). I used to have a trigger of death to check it, but I wouldn't recommend it, since you have to delete SYS tables to get rid of it :-). Bug encountered in 8.1.6 and 8.1.7, don't know about 9i, my interest for bugs decreases strongly when I have switched to something else, and my professional life is a succession of switches. BTW if the deadlock occurs on DDL locks, INITRANS and PCTFREE are totally irrelevant. - Original Message - From: [EMAIL PROTECTED] To: Multiple recipients of list ORACLE-L [EMAIL PROTECTED] Sent: Thu, 25 Apr 2002 07:18:30 We are testing an upgrade of our warehouse from 8.0.4 to 8.1.7.2. While testing our nightly load job that runs in two simultaneous streams (ascending and descending), we have been getting deadlock errors. The trace file shows the the rows waited on are no rows. In response to a TAR I opened with Oracle, Oracle responded that the application needs to be rewritten so that there is only a single stream. However our developers aren't inclined to do so because our nightly window isn't long enough for a single job and because this application worked fine as is on 8.0.4.

RE: {9i New Features: DataGuard}
I have been working on this dataguard on 8I
in this u can switch over the production to standby as production and switch
back to orignal production
by making the switch over production to
standby again.
The 9i OEM dataguard does not support 8I it
only supports 9i
so the only option is to run from command
line.
It is working fine as such i have not faced
any probs from that.

Next installment of 9i new features, like always send hate mail to
/dev/null. Also if I've lied in something feel free to correct/flame me
for it.
The Saga continues:
Oracle 9i New Features: 9i Data Guard
So you have Oracle 8i standby database, what is new with 9i standby
also known as Data Guard.
Well in theory it can be totally automated. In 8i you had to put
the database in managed recovery mode(or you manually did recovery) on the
standby db. I hope no one was doing manual recovery every time a archive

Now with 9i dataguard, the standby database can be built either:
1. manually just like you did in 8i or2. automagically

I personally couldnt get the wizard to work with 9.0.1.0. Does it
work now?, I'm not sure as I've not tested it as of recent. The manual
method works just fine.
Ok so you need to create a standby database, we're not going to cover
that here, why?, Mostly cause we're only going to cover the new aspects, you
all can read the docs as well as I can to build the db.
On to the new stuff:
Your standby database in 8i was only in what we call "delayed" protection
mode, which means there is a delay from the time the logs are completed on the
primary database before they are appliedto the standby database. Now
with 9i, you have 3 other modes:
Guaranteed protection: indicates that primary database modifications are
available to the standby database, up to the last committed transaction.
The standby database cannot diverge from the primary database at all, and no
data can be lost. If a standby database is unavailable, processing
automatically halts on the primary database as well.
Instant Protection: With instant protection, the standby database may
temporarily diverge from the primary database, but upon failover to the
standby database, the databases can be synchronized, and no data will be
lost.
Rapid Protection: With rapid protection, the log writer process transmits
redo logs to the standby sites. Use this mode when availability and
performance on the primary database are more important than the risk of losing
a small amount of data.
An important note is that in Guaranteed and Instant protection mode that
the logs are written in SYNCHRONOUS mode to the standby site. Rapid and
Delayed mode are ASYNC writes.
So this begs to ask what is the difference between Guaranteed and
Instant? Well in Guaranteed mode the logs are applied and there is no
data divergence from the primary and standby db. Whereas Instant mode
there can be data divergence but upon failover there will beNO data
loss.
So since we wont have data loss, there is a new way to "failover" to a
standby database, called switchover.
You can literally be able to switch to a standby database and switchback
to the original primary WITHOUT having to reinstantiate(ie: rebuild) the
primary.
A very nice feature, this gives you the capability to do rolling upgrade
of OS -NOTICE, NOT ORACLE BINARIES YET, ONLY THE OS.
In 8i you could only do a failover(which required rebuilding the
primary), you can still do a failover in 9i if you've lost the primary db in
some disaster like the computer room caught on fire.
Now for the automated part:
There is the dataguard manager/broker, it can be run from command
line($ORACLE_HOME/bin/dgmgrl) as well as from OEM. This gives you the
luxury of oracle doing all the work to maintain consistency between the
primary and standby database. Way too much to cover here but it handles
automatically applying logs, notification of down standby, etc.

Re: Curious question about flushing the Pool
It sounds a cute idea at first sight (pardon the mixed
metaphor) - but then what do you do about the situation
where you deliberately have a handful of versions of
the 'same' SQL which are identified by the presence of
a literal string; or the SQL that you build with one
literal and many binds because that one literal is
required to make sure that Oracle uses a histogram
on one column ?
Then there's the problem of literals which are
textually constant but variable valued such as:
sys_context('hr_hierarchy','manager');
Marginal proliferation of 'semi-literate' joke SQL
can be a good thing. Maybe yet another undocumented
hint /*+ bypass_cache_flush */ would be sufficient.
One (trivial ?) thing I'd like to see is SQL normalised
before it goes into the shared pool. Oracle 9i does it
with stored_outlines - why not with all SQL ?

I think an excellent Oracle kernel enhancement would be to bias in the
LRU scheme against SQL that uses literals, just like the buffer cache
algorithm biases against blocks that are read via full-table scan.
Think
about it... What's the likelihood that a SQL statement that's filthy
with literal values will ever be reused again in the future? Then why
store it as if it will ever be shared (i.e., reused) in the future?

Begin backup fails sporadically
Version is 8.0.6.3.0 I have several databases using the exact same set of generic backup scripts. The script that puts all tablespaces into backup mode is generated automatically and done correctly. Same is true for the script which takes all the tablespaces out of backup mode. The problem I am facing is that when this script is invoked, one (and only one) of these databases occasionally has problems. Some tablespaces are successfully put into backup mode and some say ORA-01146: cannot start online backup - file 15 is already in backup ORA-01110: data file 15: ' datafile name ' The only things that would make sense to me is if two of these scripts were running in parallel or if the prior day had some weird problem.

There are free drivers from Oracle and Microsoft. They have different behaviors. One will fail, under certain conditions, where the other will not. Use the one that works for you. There is a third party driver that works under all conditions but you have to pay for it.

While testing our nightly load job that runs in two simultaneous streams (ascending and descending), we have been getting deadlock errors. The trace file shows the the rows waited on are no rows. In response to a TAR I opened with Oracle, Oracle responded that the application needs to be rewritten so that there is only a single stream. However our developers aren't inclined to do so because our nightly window isn't long enough for a single job and because this application worked fine as is on 8.0.4. Our developers have discovered an old article (perhaps from 7.3.4 times) by Roger Snowdent The Deadly Embrace (Oracle Locking Strategies) www.dbdomain.com/120197.htm that indicates this deadlock error with no rows is an indication of an insidious table. The article states that the the INITRANS and PCTFREE parameters may be set too low for the table in use. Has anyone encountered this deadlock with norows indicated error before? If yes, how did you resolve it? In our current 8.0.4 datawarehouse database, this partitioned table has PCTFREE of 10 and INI_TRANS of 1. The block size is 8k, we are using Sun Solaris 2.6 and Veritas Volume Manager. As I said, we are preparing to upgrade this to 8.1.7. What would be an appropriate setting for PCTFREE and INI_TRANS for this large warehouse partitioned table in these circumstances? What are our options if we want to change the PCTFREE and INI_TRANS for new data that gets loaded? Can we change PCTFREE and INI_TRANS and then just keep loading more data into an existing partition? Can we change these values in new partitions and leave them the same in existing partitions? What would be the drawbacks of having some partitions with one value for these storage parameters and other partitions with different values? Also, the developers want to know if there is any utility that could be run to determine whether other tables might be susceptible to this deadlock condition. Something like dbverify or analyze with some validation option? Thanks in advance for your feedback.

[mailto:[EMAIL PROTECTED]]Sent: Thursday, April 25, 2002 1:14
PMTo: Multiple recipients of list ORACLE-LSubject: {9i
New Features: DataGuard}
Next installment of 9i new features, like always send hate mail to
/dev/null. Also if I've lied in something feel free to correct/flame me
for it.
The Saga continues:
Oracle 9i New Features: 9i Data Guard
So you have Oracle 8i standby database, what is new with 9i standby
also known as Data Guard.
Well in theory it can be totally automated. In 8i you had to put
the database in managed recovery mode(or you manually did recovery) on the
standby db. I hope no one was doing manual recovery every time a archive
log was shipped across. :)
Now with 9i dataguard, the standby database can be built either:
1. manually just like you did in 8i or2. automagically
with OEM Dataguard Wizard(crazy wizards foreverything anymore).
I personally couldnt get the wizard to work with 9.0.1.0. Does it
work now?, I'm not sure as I've not tested it as of recent. The manual
method works just fine.
Ok so you need to create a standby database, we're not going to cover
that here, why?, Mostly cause we're only going to cover the new aspects, you
all can read the docs as well as I can to build the db.
On to the new stuff:
Your standby database in 8i was only in what we call "delayed" protection
mode, which means there is a delay from the time the logs are completed on the
primary database before they are appliedto the standby database. Now
with 9i, you have 3 other modes:
Guaranteed protection: indicates that primary database modifications are
available to the standby database, up to the last committed transaction.
The standby database cannot diverge from the primary database at all, and no
data can be lost. If a standby database is unavailable, processing
automatically halts on the primary database as well.
Instant Protection: With instant protection, the standby database may
temporarily diverge from the primary database, but upon failover to the
standby database, the databases can be synchronized, and no data will be
lost.
Rapid Protection: With rapid protection, the log writer process transmits
redo logs to the standby sites. Use this mode when availability and
performance on the primary database are more important than the risk of losing
a small amount of data.
An important note is that in Guaranteed and Instant protection mode that
the logs are written in SYNCHRONOUS mode to the standby site. Rapid and
Delayed mode are ASYNC writes.
So this begs to ask what is the difference between Guaranteed and
Instant? Well in Guaranteed mode the logs are applied and there is no
data divergence from the primary and standby db. Whereas Instant mode
there can be data divergence but upon failover there will beNO data
loss.
So since we wont have data loss, there is a new way to "failover" to a
standby database, called switchover.
You can literally be able to switch to a standby database and switchback
to the original primary WITHOUT having to reinstantiate(ie: rebuild) the
primary.
A very nice feature, this gives you the capability to do rolling upgrade
of OS -NOTICE, NOT ORACLE BINARIES YET, ONLY THE OS.
In 8i you could only do a failover(which required rebuilding the
primary), you can still do a failover in 9i if you've lost the primary db in
some disaster like the computer room caught on fire.
Now for the automated part:
There is the dataguard manager/broker, it can be run from command
line($ORACLE_HOME/bin/dgmgrl) as well as from OEM. This gives you the
luxury of oracle doing all the work to maintain consistency between the
primary and standby database. Way too much to cover here but it handles
automatically applying logs, notification of down standby, etc.
Feel free to ask anything about Dataguard to me directly at [EMAIL PROTECTED]

RE: Buffer in Import
The buffer size refers to the number of bytes placed into Imports internal buffer. Generally, you should make this value large, like 5 or 10m to accommodate large data imports.

RE: Cronjob
Ahmadsyah, If I remember correctly (my Vax is a couple of years old), we set up two jobs to accomplish this. One job ran every day. All this job did was to start the real job schedule job. the job schedule job interrogated what day of the week it was and ran other jobs. For example, if today is Thursday, it would start all jobs that were supposed to run on a thursday. the final thing that this job did was to re-schedule the first job for tommorrow at the same time.

Waleed, There used to be a single process that loaded the data. It ran too long and the application owners split the job out into two process. One started at one end and loaded data in ascending order and the other started at the other end and loaded in descending order. Both jobs run at the same time in the same database.

Re: No Rows Deadlock and PCTFREE, INITRANS on 8.1.7.2
Jonathan, Following is section of the trace file generated. It is a TX lock. I'm not sure whether it is mode 4. How can I tell? We upgraded using the migration script, not export/import. During the nightly loads we have always dropped the indexes on the foreign keys on this large fact table and never had any problems at 8.0.4. Those foreign key indexes were dropped before this load. I got another recommendation from Anjo Kolk to increase INITRANS to 2. The problem is that this very large partitioned table cannot be exported/imported in it's entirety during our regular maintenance window. Is that a requirement for changing INITRANS? Could we just do this on new partitions? It is not a problem with existing rows but rather with new rows being inserted (according to our developers). Thanks for your helpful reply.
