Well, sometimes developers are asked to generate ad-hoc reports for management. In those cases, it's pretty easy to accidentally generate the query from heck and need to kill it. The earlier suggestion of writing a procedure and granting execute rights on that procedure is an approach I have heard of before. What I've generally seen is a stored procedure that checks to make sure that the session the user is trying to kill is their own, probably logs the kill in some sort of audit table, etc. I don't have much of a problem with a developer killing their own session even in production.

Notice that the value for log file sync seems a bit

This is not a terribly fast system, but it should
not be this slow.

With an 8k block, that is about 36k per commit.
Somewhat less than the
10m per commit I expected.
Suspecting that the LONG datatype in some of the
tables may be the
culprit, a quick perusal of TFM
reveals the following regarding the use of the LONG
datatype with the imp
utility:
The integer specified for BUFFER is the size, in
bytes, of the buffer
through which data rows are transferred.
BUFFER determines the number of rows in the array
inserted by Import.
The following formula gives an approximation of the
buffer size that
inserts a given array of rows:
buffer_size = rows_in_array * maximum_row_size
For tables containing LONG, LOB, BFILE, REF, ROWID,
UROWID, or DATE
columns, rows are inserted individually.
The size of the buffer must be large enough to
contain the entire row,
except for LOB and LONG columns.
If the buffer cannot hold the longest row in a
table, Import attempts to
allocate a larger buffer.
So, the buffer parameter has no effect on tables
containing columns of the
type long, lob, bfile, ref, rowid, urowid or date.
This seems rather limiting for such an important
utility. This applies to
versions 8.1.7 and 9.2.0
I ran a test to load 90k rows into 2 different
tables, the only difference
being that one used a long column for text
Re: Read Only TBS Backup Confirmation
Gene, That's the purpose of read-only tablespaces. You make to changes you need in the data, alter it to read only, and back it up to the backups device(disk,tape) and but the backup on the shelf.

Important Program Announcement: Oracle University Hands-On Course
Requirement
Oracle customers and business partners are demanding hands-on experience
- with all aspects of Oracle's database - from their Oracle Certified
Professionals. In order to meet our commitment to our customers and
constituents, Oracle University has recently made a significant
investment in its Certification Program. Three distinct changes are being
rolled out with the goal of increasing the level of quality of our
certification skill and ability benchmarks:
·Scenario-based
testing in all Oracle9i DBA Certified Professional exams .
·Instructor-led
class requirement for candidates starting on the Oracle9i DBA Certified
Professional credential exam path.
·A
new hands-on Masters Practicum Exam for the Oracle9i Database
Administrator Certified Master credential.
at
http://www.oracle.com/education/certification/index.html?dba9i_ocp.html
Instructure-led class is a requirement.
You CAN take the Online Training to _prepare_ for the Exams. But
you MUST attend at least one Instructor-led class
to qualify for the certification.

Re: Import foibles
Yes, I once imported a schema [Parametric Windchill] which had a few tables
with LONG datatypes.
It was one particular table that took ggg to import.
Import does import one-row-at-a-time for tables with LONGs . But I
couldn't explain
why one table took so much longer than the others.
I just kept logs of the export and import sessions but didn't follow up as

RE: data file permissions --
SyncSort is NOT a data unloader. It's purpose, and it does a damned good job of it, is to sort large text files to improve data loading with tools like SQL*Loader. Your user should have zero access to the datafiles, period. They need to be -rw-r so that an ipc dedicated server process will work. But under NO circumstances should that be changed. Doing so can make for a VERY long night of recovering a database.

The only unloader that reads files directly is the notorious DUL. I haven't had any experiences with DUL, but according to what I know, I wouldn't even want to have it. Now there is a system call named chmod and oracle takes care that only oracle RDBMS can access files. Nobody but the DBA can even sniff database files. Please, execute that user.

Snapshots are refreshed by the FAST method using dbms_refresh.refresh. However, do to the extremely high transaction rates on our database, we're getting ORA-1555 when trying to refresh the snapshots. The mlog$ tables builds up and the slave just keeps on falling behind. From what I can see, snapshots are refreshed as a single large transaction. So if there are 500K rows in the mlog$ table, all 500K will be processed in one go. There are no intermediate commits. So my question is: how do you specify a commit point with snapshots? I'm looking for parameters similar to that of the exp and sqlldr utility where you can specify commit points. I've logged an iTAR with Oracle Support and there answer is that it's not possible. ARGH!! Here's another crazy question is - has anyone updated the dbms_refresh package to add a commit point? Or, have you tried to interogate the mlog$ and write a PL/SQL procedure to process the rows in there, thereby having your own commit points? mlog$ provides the primary keys and the DML type. So surely it's just a matter of going through each one of the row and applying it to the slave?

Re: Reset sequence at midnight
Interesting, I've actually had to do this before. Be forewarned that this is not a good method to use for a very busy app, as it does introduce some level of serialization. control access to the sequence through a package Within the package use a function that sets a lock via dbms_lock.request and then immediately release the lock. The purpose of this will become clear in a moment. Create a procedure within the package that will be used to reset the sequence to 0. It is not necessary to drop the sequence to do this. eg. drop sequence s; create sequence s start with 100; select s.nextval from dual; declare vs integer; inc integer; junk integer; begin select s.nextval into vs from dual; inc := 0 - vs; execute immediate 'alter sequence s minvalue ' || inc; execute immediate 'alter sequence s increment by '||inc; select s.nextval into junk from dual; execute immediate 'alter sequence s increment by 1'; end; / select s.nextval from dual; The procedure that does this just needs to take the same dbms_lock.request that the function mentioned earlier takes. The difference is that it does not release the lock until the modification of the sequence is completed. This forces any requests for new sequence numbers to wait for the modification to the sequence to complete.

Important Program Announcement: Oracle University Hands-On Course
Requirement
Oracle customers and business partners are demanding hands-on experience -
with all aspects of Oracle's database - from their Oracle Certified
Professionals. In order to meet our commitment to our customers and
constituents, Oracle University has recently made a significant investment
in its Certification Program. Three distinct changes are being rolled out
with the goal of increasing the level of quality of our certification skill
and ability benchmarks:
Scenario-based testing in all Oracle9i DBA Certified Professional
exams .
Instructor-led class requirement for candidates starting on the
Oracle9i DBA Certified Professional credential exam path.
A new hands-on Masters Practicum Exam for the Oracle9i Database
Administrator Certified Master credential.
at http://www.oracle.com/education/certification/index.html?dba9i_ocp.html
http://www.oracle.com/education/certification/index.html?dba9i_ocp.html
Instructure-led class is a requirement.
You CAN take the Online Training to _prepare_ for the Exams. But you MUST
attend at least one Instructor-led class
to qualify for the certification.

My understanding is that you need to take a class that corresponds to one of
the four OCP exams, which are all 5-day classes. The in-classroom versions
run $2500 and the on-line versions run $1250. Oracle partners get a 35%

discount).

For taking Oracle9i OCP exam is it necessary to have attended a Oracle

I had planned the Miracle Master Class Teambuilding Exercise as follows: 1. On Sunday evening we would (slowly!) move the stuff from the loft downstairs and stack it carefully. 2. On Monday evening we would put in the new flooring. 3. On Tuesday evening we would put the stacked stuff back up on the loft. As it turned out, it ended up a bit different from the original plan: 1. On Sunday it took the Oakies about 42 minutes to remove everything from the loft. Most of it was thrown out, and Peter Gram even had to rent a new trailer for the junk. 2. Lex and Carel-Jan and Gary Goodman and James Morle and Jon (from Miracle Iceland) were un-stopable and made 80% of the flooring on Sunday. 3. On Monday Lex got the bright idea of doing some heavy changes to the whole construction of the Garage. Which he and Carel-Jan and helpers then did. 4. On Tuesday evening nobody did anything except participate in the Gala Dinner and visit the famous hotdog stand Bjarne's Poelser. 5. I don't know when the stuff is going up there again. I'm afraid.

RE: Oracle vs Mysql
DBI is an extension to perl language which can then be used by perl to talk with various databases. DBI stands for database interface. With DBI you also have to load in a specific database driver which is called DBD. For instance for oracle you have to install DBI and DBD::Oracle. Its really cool to use and very fast. I wrote a poor man's replication built on DBI/DBD::Oracle/DBD::Sybase. I like mysql but the sql is just not that rich as it is in oracle. They are fixing some of the shortcomings soon so it will be pretty competitive is basic database usage with Oracle.

Re: Oracle vs Mysql
I'm suspicious about using MySQL or Postgres with a database 100 gigabytes in size. (Especially, when their main website appeared to be down when I wanted to check some of their recent references). Anyway, if you have availability requirements which don't allow you to take down your system for backup, then you have to use replication (about which quality I'm suspicious again) in order to take online backups from a clone db. For that you need another 100GB of storage. Anyway, if I was persuaded to go with MySQL or Postgres for large databases, I'd try to split them up somehow (kind of partitioning), if possible, to have separate databases with separate server processes serving them. That way taking down or crashing of one server wouldn't affect other data that much...

Application Server Caching
I heard a presentation from a front end performance analyst last night from www.tangasol.com (im not associated with them at all). He was pretty impressive. He argued that accessing the database is expensive. He also argued in favor of caching data at the application server level. Have any of you worked with this? What are your opinions? His opinion was that people go back to the database to ask the same question way too often and cause a botteneck, if you can cache these frequently asked questions at the front end, it will significantly scale better.
RE: Application Server Caching
Ryan, He has a point. If you look at 9IAS's architecture there is a cache database at the apps server. The trick is to know when the data your looking for in cache is no longer valid.

Re: Application Server Caching
Ryan, Our application does a certain amount of application server caching, and infact has a pretty advanced cache mechanism to deal with out of date objects, etc. On a more simple level - Common reference records are loaded at start up and cached, error messages are cached, etc. In a similar fashion we a a sequence providing GUID values (global across our application at least) - Obviously the application chews through these very fast (millions per day). So, to reduce load each time the application gets a new value from the sequence it treats it as a range of 1000 values. If the app crashes we only loose a few thousand sequence numbers (several processes each have their own store of 1000 values) but access to the sequence is reduced by a factor of 1000. After three years of running the sequence is around 10,000,000 instead of 10,000,000,000! It's all a matter of knowing what to cache and how to ensure it's still current. If you were populating a list of State Codes for a drop down list then I would cache that result but something like a StockOnHandQuantity figure probably changes so often that caching is of little use. If you have the same query (ficticious eg: select statename, statecode from states) constantly firing in your database then I guess it's a sign that caching would help. Even sub-second queries can quickly add up in a busy system. Cheers, Mark.

Snapshots are refreshed by the FAST method using dbms_refresh.refresh. However, do to the extremely high transaction rates on our database, we're getting ORA-1555 when trying to refresh the snapshots. The mlog$ tables builds up and the slave just keeps on falling behind. From what I can see, snapshots are refreshed as a single large transaction. So if there are 500K rows in the mlog$ table, all 500K will be processed in one go. There are no intermediate commits. So my question is: how do you specify a commit point with snapshots? I'm looking for parameters similar to that of the exp and sqlldr utility where you can specify commit points. I've logged an iTAR with Oracle Support and there answer is that it's not possible. ARGH!! Here's another crazy question is - has anyone updated the dbms_refresh package to add a commit point? Or, have you tried to interogate the mlog$ and write a PL/SQL procedure to process the rows in there, thereby having your own commit points? mlog$ provides the primary keys and the DML type. So surely it's just a matter of going through each one of the row and applying it to the slave?

Re: Application Server Caching
Just to elaborate - I did a poor job of explaining the sequence trick. If the sequence returns a value of 12345 then the application knows it has a range from 12345000 to 12345999 to use. The next process will get the sequence value 12346, providing a range from 12346000 to 12346999. The long numbers are used in the database to be unique but having the application do a multiplication by 1000 certainly reduced load on the sequence.

Re: Veritas Backup Question
OK, Teresita, what is your question? Do you have MLM? Did you put the database in the backup mode? Did you save archives? How about the control files? Did you backup control files? I doubt that this forum is an appropriate place for a backup recovery course, but it seems that you have a good incentive to learn. First advice is to try to restore database and see whether you can actually recover. If you can, well, you're a pro. If you can't get backup and recovery book, one of Rama Velpuri's, if possible. My favorite is V7 book, because it's not too thick, it's very clear and well written and I like the color of copper. The most important thing about backup and recovery is never to allow yourself to run out of coffee. On 2004.01.14 21:14, Teresita Castro wrote: Hi!!

RE: Hi!!
Teresita, What your DBA is talking about is Oracle's RMAN backup utility. There us an interface from Oracle to Veritas which allows RMAN to use Veritas as a librarian for the backups. The first thing I'd suggest is finding out what version of Oracle your using. There are significant differences in using and setting up the RMAN and Veritas software between the two. Check out the documentation CD on RMAN that shipped with your database.
