All the fields are schema.tablename.fieldname. The SQL has 3 inline queries that are the same but with different months in the where clause. Simplified version: select acct . from tab1, tab2, where ... and acct in (select acct from tab1 where balance 7000 and month = 2) and acct in (select acct from tab1 where balance 7000 and month = 3) and acct in (select acct from tab1 where balance 7000 and month = 4) group by acct; Now the query runs OK with only one sub query.

Urgent: Prodution database recovery

Advice needed please
Oracle 8.0.5 Tru64 4.0f One of our developers here is writing a utility to provide fast unloads of tables (to replace fastunloader as it happens) His problem is as follows. Start from the bottom and work your way up. I would be really grateful if anyone can offer up some alternatives for us. Regards Lee -Original Message- From: Dudley Dave - ddudle Sent: 29 May 2002 16:04 To: Robertson Lee - lerobe Subject:RE: Do you still have that SQL Expert? No, you miss the point. I'm explicitly NOT using PQ (or at least not explicitly using it). Using a parallel hint on huge table unloads - with the single-threaded version of the code (i.e. pipdynsql.v2.0.0) didn't seem to make much difference at all. I didn't do the tests directly though, poeple on the account did. So it may be that the tables already had a degree of parallelism built in, in which case I'd guess the hint would be redundant. What I mean is that even if you use PQ for the server to extract the data in parallel you still have the bottle neck of a single client to send it all back to. That's what I was trying to get around. Assuming that we're not generally using the full network bandwidth, I'd assume that multiple clients ought to be able to dump out separate sections of a table at the same time, at roughly the same speed at a single client would unload a single table - i.e double the throughput. But I can't find anything on the web to tell me the best / most efficient way to actually do this. (By the way, I've tried the NO_PARALLEL hint too, to stop the server setting off too many conflicting slaves on its side. Again no better as far as I could tell.) N.B. Not sure if you'd suggest it, but before you do: most of the tables we'd really want to use this for are massive, and so are already partitioned. So where I say table I mean either that or a partition thereof. Besides, need a generic solution that doesn't rely on having to partition your table to unload it quickly. By the way, I'm specifically testing speed of my original code (e.g. pipdynsql.v2.0.0 user/pass select * from table) against the new multithreaded development code - i.e. regardless of the machine load at the time, I want to see if multiple simultaneous unloads can be quicker than a single unload client (at the expense of using more machine / Oracle resource obviously). Is this making sense? Dave -Original Message- From: Robertson Lee - lerobe Sent: 29 May 2002 15:14 To: Dudley Dave - ddudle Subject:RE: Do you still have that SQL Expert?

OK Clever-Trousers, As you're so hot on table/index disk striping... I've written the program pipdynsql, which as you may have heard (this lunchtime if not before), people want to use to replace FastUnloader. I've been playing about with a new multithreaded version to try to download a table in sections to multiple client threads which then write back out to a single file (either ordered, or for max speed in random/undefined order). Can you think of any quick ways to do this, or tricks to try? I've tried ranges of rowids (as I'm told that's hold parrallel query works) but the ROWID (tab) hint does not seem to go through the table in rowid order. And it's a massive overhead to order by rowid to work out non-overlapping ranges. And even if you do, you have to say WHERE rowid = xxx AND rowid = xxx (as I say, can't force it to go in ROWID sort order) so this tends to be slower than nect opt... tried assuming there's a unique index and giving start points to each slave thread, which then selects a set number of rows. This is prety quick, but even this seems slower than a simple SELECT * FROM table (for the same number of records). tried loading temp rowid tables with sets of rowids and each slave does a full table scan of its rowid set table, with where clause connection to the data table. Can't find anything better than my original method which selects a unique key from an index with a master thread, for every x'th rownum. Then hands these out to the slave threads to select * from table where unique key = given key for specified number of records. e.g. master pulls out every 100,000th key with a modulus and each slave dumps out 100,000 rows at a time, starting at the key its given.

Rachel, I agree with your short list of the areas of responsibilities but I would change the word application to development. An application DBA, from the people I have talked to, is quite busy performing the upgrades and patches that accompany the Oracle Applications. The applications database generally has many, many tables, triggers and constraints and is constantly the target for upgrades and patches from Oracle. It is a time consuming task as the majority of the different applications (financial, HR, Purchase Order, etc) have hooks into each different package and are so intertwined that any small fix in one involves patches for the others. There are only a few user defined tables as each package has their own named tables that are partially shared between packages. There is very little if any work you can do on the application code because it is so intertwined and customized when it is installed. Any upgrades require that the customization be reworked to make it fit into the new version of the application package. It takes a longer time to install than a standard database, on the magnitude of days, and requires a dedicated and investigative mind set to maintain. To the list you created I would add: Help desk call recipient, network support, client support, software and hardware evaluation, whipping post, IT team member (possibly team leader), self driven, office coffee maker, consumer of various liquids. Ron ROR mª¿ªm [EMAIL PROTECTED] 05/29/02 04:50PM that's not a bad definition :) seriously, everyone will have their own definition, mine is: production dba -- responsible for all databases that are considered production. this includes but is not limited to: backups recovery testing contingency testing production performance tuning (should mostly be database tuning as SQL really should be tuned at the development stage, with information passed back from the production DBA) documentation of all procedures space management on production systems, including capacity planning and projection of growth change management monitoring external data loads into production database health checks on production database application dba -- responsible for all databases in which developers have access. responsibilities: SQL tuning (not SQL coding!) database design, in conjunction with the developers any and all changes to the application schema working with the production DBA to ensure production performance (see SQL tuning!) backups (these might be weekly offline backups, as development is usually less critical but then again maybe not) as deadlines creep closer, the weekends off may not be this is just the short list I've usually been both the production and application dba where I've worked.

Re: Wait time for SQL*Net message
Hi Type more and a lot faster and hit more enters while sending querries to the database. :-) I would not worry about SQL*Net message from client, it simply means that your client has received the data from the last request and now the server is waiting for the next.

RE: Bind Variable values
Ravi - According to Metalink Note:171647.1, There are four levels available when setting up trace with Event 10046 - · Level 1 is the default. This level traces all activities until the trace session is stopped. · Level 4 provides level 1 tracing and displays the entered value for all bind variables.

RE: Re[2]: So, What is a 'Production DBA'?
Not sure I agree with prior statements. The Production DBA is the single person(s) responsible for the livelihood and availability of production database environments. He/She/It is the first line of contact should a database-centric application either not perform to expectations or crash. The Production DBA is responsible for environment tuning/performance/optimization, disaster recovery, backup/recovery, security, generic administration, etc. They are also responsible for enforcing production standards for all application development teams and ensuring that all is smooth. In many cases the Production DBA has the same responsibilities for the development environment to ensure that all guidelines are followed as software is transitioned from Development to test to validation and finally production. The Application DBA is responsible for the overall integrity of a specific application. They are responsible for the physical implementation of the logical data model for that application, application-specific performance issues, application-specific security issues, etc. Note the theme: application specific. This could include any application, even Oracle eBusiness Suite. Application DBAs are DBAs!!! However, many are just starting out in the field so this position was created by many organizations to let them get their feet wet. The primary difference between the two. One absolutely needs a pager and doesn't sleep. The other does. Thank You Stephen P.

Re: Bind Variable values
Set the SQL trace event (10046) to level 4 to dump the values of the bind variables. If you can enable SQL trace from within the session, you can use... alter session set events '10046 trace name context forever, level 4'; If you cannot alter the source code or otherwise enable SQL trace from within the session, you can do it from a SYSDBA session: SQL*Plus ORADEBUG SQL oradebug setospid OS-pid-of-server-process SQL oradebug event 10046 trace name context forever, level 4 DBMS_SYSTEM package exec dbms_system.set_ev(sid,serial#, 10046,4,''); I have a PL/SQL procedure named TRCLVL12 posted on my website (http://www.EvDBT.com/tools.htm) which demonstrates the use of the SET_EV procedure. I also have UNIX korn-shell scripts named traceon.sh and traceoff.sh at the same website which demonstrate the use of ORADEBUG. However, be aware that both utilities are setting SQL trace level 12, which is a combination of level 4 (bind variables) and level 8 (display wait event info) and produces huge trace files...

RE: Advice needed please
Lee - Just some reactions, few answers. - Generally a process like this will be disk-bound, not CPU-bound, so idle CPU time is to be expected unless your disk is REALLY fast. - Multiple simultaneous full-table scans may not be any faster because the disk heads may need to flit to and fro in order to satisfy each process' request. Sometimes a single full table scan is as fast is it gets for a mechanical device like a disk. RAID will be faster, of course, but ultimately the RAID is composed of disks. - Trying for something faster than select * is a real challenge. To perform a full table scan, Oracle must read each data block. The alternative is index scanning, but this means reading an index block, fetching a data block, etc. Not faster if you're going to eventually read all data blocks anyway. - If select * isn't fast enough, you should consider using table partitioning. That way each process can separately scan a separate partition and separately write to your output files. Hopefully someone else will think of a bright idea I've missed.

I'm explicitly NOT using PQ (or at least not explicitly using it). Using a parallel hint on huge table unloads - with the single-threaded version of the code (i.e. pipdynsql.v2.0.0) didn't seem to make much difference at all. I didn't do the tests directly though, poeple on the account did. So it may be that the tables already had a degree of parallelism built in, in which case I'd guess the hint would be redundant. What I mean is that even if you use PQ for the server to extract the data in parallel you still have the bottle neck of a single client to send it all back to. That's what I was trying to get around. Assuming that we're not generally using the full network bandwidth, I'd assume that multiple clients ought to be able to dump out separate sections of a table at the same time, at roughly the same speed at a single client would unload a single table - i.e double the throughput. But I can't find anything on the web to tell me the best / most efficient way to actually do this. (By the way, I've tried the NO_PARALLEL hint too, to stop the server setting off too many conflicting slaves on its side. Again no better as far as I could tell.) N.B. Not sure if you'd suggest it, but before you do: most of the tables we'd really want to use this for are massive, and so are already partitioned. So where I say table I mean either that or a partition thereof. Besides, need a generic solution that doesn't rely on having to partition your table to unload it quickly. By the way, I'm specifically testing speed of my original code (e.g. pipdynsql.v2.0.0 user/pass select * from table) against the new multithreaded development code - i.e. regardless of the machine load at the time, I want to see if multiple simultaneous unloads can be quicker than a single unload client (at the expense of using more machine / Oracle resource obviously).

RE: Advice needed please
Thanks Dennis. Anything whether it be a reaction or an answer, is welcome. Regards Lee -Original Message- Sent: 30 May 2002 15:08 To: Multiple recipients of list ORACLE-L Lee - Just some reactions, few answers. - Generally a process like this will be disk-bound, not CPU-bound, so idle CPU time is to be expected unless your disk is REALLY fast. - Multiple simultaneous full-table scans may not be any faster because the disk heads may need to flit to and fro in order to satisfy each process' request. Sometimes a single full table scan is as fast is it gets for a mechanical device like a disk. RAID will be faster, of course, but ultimately the RAID is composed of disks. - Trying for something faster than select * is a real challenge. To perform a full table scan, Oracle must read each data block. The alternative is index scanning, but this means reading an index block, fetching a data block, etc. Not faster if you're going to eventually read all data blocks anyway. - If select * isn't fast enough, you should consider using table partitioning. That way each process can separately scan a separate partition and separately write to your output files. Hopefully someone else will think of a bright idea I've missed.

I'm explicitly NOT using PQ (or at least not explicitly using it). Using a parallel hint on huge table unloads - with the single-threaded version of the code (i.e. pipdynsql.v2.0.0) didn't seem to make much difference at all. I didn't do the tests directly though, poeple on the account did. So it may be that the tables already had a degree of parallelism built in, in which case I'd guess the hint would be redundant. What I mean is that even if you use PQ for the server to extract the data in parallel you still have the bottle neck of a single client to send it all back to. That's what I was trying to get around. Assuming that we're not generally using the full network bandwidth, I'd assume that multiple clients ought to be able to dump out separate sections of a table at the same time, at roughly the same speed at a single client would unload a single table - i.e double the throughput. But I can't find anything on the web to tell me the best / most efficient way to actually do this. (By the way, I've tried the NO_PARALLEL hint too, to stop the server setting off too many conflicting slaves on its side. Again no better as far as I could tell.) N.B. Not sure if you'd suggest it, but before you do: most of the tables we'd really want to use this for are massive, and so are already partitioned. So where I say table I mean either that or a partition thereof. Besides, need a generic solution that doesn't rely on having to partition your table to unload it quickly. By the way, I'm specifically testing speed of my original code (e.g. pipdynsql.v2.0.0 user/pass select * from table) against the new multithreaded development code - i.e. regardless of the machine load at the time, I want to see if multiple simultaneous unloads can be quicker than a single unload client (at the expense of using more machine / Oracle resource obviously).

Re: So, What is a 'Production DBA'?
I feel that it is hard to draw the lines between Application and Production DBA's. For example where would you place the DBA that maintains SAP? Without the application knowledge he/she/it wouldn't get very far. Also I have been wondering something and this thread seems a good place to ask. Is there a historical feud between DBA's and Developers? Coming from a consulting/software house I find some of the comments funny but can't believe that there is that quantity of bad developers. Most of the DBA's we deal with have come up through the ranks and started as developers. From: Ron Rogers [EMAIL PROTECTED] Reply-To: [EMAIL PROTECTED] To: Multiple recipients of list ORACLE-L [EMAIL PROTECTED] Subject: Re: So, What is a 'Production DBA'? Date: Thu, 30 May 2002 04:48:29 -0800 Rachel, I agree with your short list of the areas of responsibilities but I would change the word application to development. An application DBA, from the people I have talked to, is quite busy performing the upgrades and patches that accompany the Oracle Applications. The applications database generally has many, many tables, triggers and constraints and is constantly the target for upgrades and patches from Oracle. It is a time consuming task as the majority of the different applications (financial, HR, Purchase Order, etc) have hooks into each different package and are so intertwined that any small fix in one involves patches for the others. There are only a few user defined tables as each package has their own named tables that are partially shared between packages.

Re: So, What is a 'Production DBA'?
ron, I've usually seen the term Apps DBA for the DBA who deals with Oracle Applications. As for using development dba vs application dba I was using the terminology of the original poster. My feeling is, separating these functions just adds to overhead and disconnect in solving problems... more places to point fingers and say it wasn't me, it was fill in the name's problem Rachel --- Ron Rogers [EMAIL PROTECTED] wrote: Rachel, I agree with your short list of the areas of responsibilities but I would change the word application to development. An application DBA, from the people I have talked to, is quite busy performing the upgrades and patches that accompany the Oracle Applications. The applications database generally has many, many tables, triggers and constraints and is constantly the target for upgrades and patches from Oracle. It is a time consuming task as the majority of the different applications (financial, HR, Purchase Order, etc) have hooks into each different package and are so intertwined that any small fix in one involves patches for the others. There are only a few user defined tables as each package has their own named tables that are partially shared between packages.

Directio bypasses the operating system (ADVFS file system) caching and is more efficient; however, ADVFS does not cache any data or pre-fetch read data.For single block random reads directio is a performance improvement--there is less O/S overhead and Oracle does a good job of managing the buffer cache. However, Oracle does not hold multiple block reads in its cache, so if your workload involves a large number of multi-block reads directio is a performance detriment.The blocks are not cached, so re-reads require physical I/O for each read, and Oracle does not pre-fetch data as ADVFS does, so the application incurs more I/O wait. Also, any subsequent access after a file is opened in directio mode inherits the directio mode. This may impact other applications reading the files outside of the database activity--for example backup. In our experience using the Oracle Applications (ERP) suite, overall performance was better with directio disabled. By default directio is enabled if running 8.1.6 or later and Tru64 5.0a or later.The flag to disable was introduced in 8.1.7.2, I believe. We were told not to run 8.1.7.2 on Tru64 (buggy), so we have implemented 8.1.7.3. The default operating mode is: _tru64_directio_disabled = FALSE This enables directio. If you set it TRUE, then the RDBMS I/O will function as it did before--using normal I/O.

LISTCMDB = (DESCRIPTION_LIST = (DESCRIPTION = (ADDRESS_LIST = (ADDRESS = (PROTOCOL = TCP)(HOST = kfplcmdb)(PORT = 1522)) ) (ADDRESS_LIST = (ADDRESS = (PROTOCOL = TCP)(HOST = kfalcmdb)(PORT = 1522)) ) (ADDRESS_LIST = (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC_CMDB)) ) ) ) SID_LIST_LISTCMDB = (SID_LIST = (SID_DESC = (SID_NAME = PLSExtProc_CMDB) (ORACLE_HOME = /cmdb/u0x/u01/app/oracle/product/8.1.7) (PROGRAM = extproc) ) (SID_DESC = (GLOBAL_DBNAME = CMDB) (ORACLE_HOME = /cmdb/u0x/u01/app/oracle/product/8.1.7) (SID_NAME = CMDB) ) ) Sitting on our RMAN database machine, pinging kfplcmdb does not work but pinging kfalcmdb works fine. On th emachine to be backed up: why can't I use kfalcmdb in the listener.ora file? The listener works fine when using kfplcmdb. This is 8.1.7 on Solaris 8. Thanks, Helmut

I am required to have multiple servers for redundancy and I can schedule query only time which is not equal to sla downtime. This window could be used to rebuild the dictionary on an activated standby. The fact that it works fine and Oracle doesn't support it makes me whine, sometimes in plubic. I guess I wouldn't suggest that Li Zhang upgrade both server and oracle at the same time, anyway. It takes almost no time to shut down an 8.1.7.0 instance and start it up on an 8.1.7.2 ORACLE_HOME on the same server. The part that takes a long time is re-running catalog, catproc, etc., which I've never understood why you have to do, and which you have to do with the database open and only you logged in. You shouldn't need a standby to perform a fast upgrade even in a supported manner. Rerunning catalog and catproc takes much too long. Oracle should figure out the small number of objects that need to be recompiled under a new binary and provide a script with just those in it. Rerunning everything is a waste of time, and resources, and is disruptive as well. Anyway, since the log format of 8.1.7.0 is the same as 8.1.7.2, there should be no real problem running the standby in this mode, which I'll take you word for it is unsupported. The question is, why would someone do it? Disk space for ORACLE_HOME?

Re: So, What is a 'Production DBA'?
all it takes is one bad developer (commonly referred to as a duhveloper) to spark the flames remember, dilbert makes its money on the BAD side of software development, there is no humor (and in our cases, no angst) when the people do the jobs they are supposed, on time and properly. In my own case, I would say that 95% of the developers I have worked with have been really good at what they do, involved and interested enough to learn something about how Oracle works under the covers and not just how to code SQL. And yes, I started as a developer, although I've never been an Oracle developer.

RE: So, What is a 'Production DBA'?
Jay Yes, many of us were developers and for awhile you have the illusion that they should accept you because you are one of them. Eventually you realize the relationship isn't that simple at all. The problems usually come from perspective, interests, and priorities. Many senior developers have an interest in learning about the database and I trust them to perform many tasks. Other developers have little interest in the database and I am constantly worried about ensuring they can't damage the database. As a production DBA, you must have a system-wide perspective, and many developers just think about their program as if it ran on a single-user PC. Some of their tuning may affect the system performance adversely, like not using bind variables. And lastly, their priority is getting their program completed and running as quickly as possible while your priority is keeping the database running. Therefore you should respond to their request as quickly as possible to meet their deadline. Dennis Williams DBA Lifetouch, Inc.

RE: rman duplicate dbid?
Bill Perhaps you created one by cloning it from the other one. This can change the SID, but won't change the DB_ID. RMAN can't deal with multiple instances with the same DB_ID. The simplest way around this is to create a separate RMAN catalog for one of them (just create a separate username). Actually, I'm becoming convinced that maybe the way to go is to create a separate catalog for each production database. This gives you more flexibility, and I haven't seem any disadvantages to this.

RE: So, What is a 'Production DBA'?
Gene - C'mon ya gotta give us more details. I have heard that most DBAs either come from developers or sys admins, but I can't recall a former sys admin, or maybe they just didn't mention it. I am curious about your observations on the best and worst qualities of each variety. I feel that a former developer might make a better development DBA because he/she might understand things from the developer's perspective. I could see where it might take a developer turned production DBA awhile to understand a systems perspective. If the developer only created code on a PC, it might take awhile to really get a system-wide perspective (or never). Maybe you'll give me a better appreciation for my sys admin.

RE: how to changes the sequence no for the redologs
Dennis, I beg to differ with you on this issue. To keep the naming convention simple for the logs and to be able to differentiate between different instances logs, you may have to use 4 characters plus the sequence number for the log name. as an example PRDA+seq.log and PRDB+seq.log. If the OS does NOT allow long names the logger will halt after the sequence . It would be nice to just reset the logs to 0001 and move along its merry way. I learned this fact this weekend when the logs reached on a Novell os (admin stated that the long names was enabled). I had to change the log naming convention to PRA+seq.log and the problem was corrected. Now I monitor the log sequence closely and will rename again if needed. Ron ROR mô¿ôm [EMAIL PROTECTED] 05/29/02 06:28PM Sarath - Only an incomplete recovery resets the logs, whether you are on Oracle 7 or Oracle 8i. Essentially you pay the big license fees to Oracle to prevent that from occurring any more than it possibly needs to. I'm not sure why you want the sequence reset. Just for neatness? You have many years before the sequence is exhausted. Be patient, your life as a DBA isn't likely to always be this boring. Dennis Williams DBA Lifetouch, Inc.

RE: rman duplicate dbid?
Bill - Glad that method of changing the db_id worked for you. The advantages I see for separate RMAN catalogs are: - If you need to upgrade the target database, you can do that without affecting the other databases. For example, if the upgrade requires a change to the catalog schema, you can just change it for that database without worrying about it affecting the other databases. - If you bollix up the catalog, in the worst case you clear it out and start fresh. You probably limit the damage to a single schema/target database. - In the development scenario, databases come and go. I can't recall an RMAN command like delete all traces of a database. But you can export and drop the schema. - You may decide to relocate the catalog for a database to another instance and/or host. Separate catalogs give you this flexibility. - My systems people like the philosophy of a backup tape(s) containing everything you need to recreate the system. I can run the backup to disk, export the RMAN catalog schema and FTP it over to the target system before tape backup starts, so everything winds up on a single tape. Now I just need to prove that I can mount that tape on another system and get the database going again. - As a novice, it may be easier to review the schema tables, and if you decide to clean out some records, it is simpler. I haven't seen any downsides to having multiple catalogs, but would appreciate if anybody knows of any. Dennis Williams DBA Lifetouch, Inc.

Oracle does not support prod at 8.1.7.0 and standby at 8.1.7.2. I think this is a real crime, since it would be a great feature to lower downtime. Why? Because of some local operational issues. I am required to have multiple servers for redundancy and I can schedule query only time which is not equal to sla downtime. This window could be used to rebuild the dictionary on an activated standby. The fact that it works fine and Oracle doesn't support it makes me whine, sometimes in plubic. I guess I wouldn't suggest that Li Zhang upgrade both server and oracle at the same time, anyway. It takes almost no time to shut down an 8.1.7.0 instance and start it up on an 8.1.7.2 ORACLE_HOME on the same server. The part that takes a long time is re-running catalog, catproc, etc., which I've never understood why you have to do, and which you have to do with the database open and only you logged in. You shouldn't need a standby to perform a fast upgrade even in a supported manner. Rerunning catalog and catproc takes much too long. Oracle should figure out the small number of objects that need to be recompiled under a new binary and provide a script with just those in it. Rerunning everything is a waste of time, and resources, and is disruptive as well. Anyway, since the log format of 8.1.7.0 is the same as 8.1.7.2, there should be no real problem running the standby in this mode, which I'll take you word for it is unsupported. The question is, why would someone do it? Disk space for ORACLE_HOME?

RE: So, What is a 'Production DBA'?
I know I'm probably going to regret replying to this thread. I'm one of those people who spent years as a programmer...and wound up somewhere in between applications and tech support because I couldn't get the tech support I needed. When we got SAP'd in '93, I finally gave in to becoming a so-called DBA to keep the legacy systems running (not Oracle based) AND keep the SAP project afloat. So I'm probably one of those SAP babysitters. I would love to be able to hire a development or applications DBA (we also have non-SAP Oracle databases) but the skill set I need in an individual to actually reduce my work load is much broader than the typical Oracle development or applications person. I know there can be exceptions, of course, but I haven't found development or applications people to be too concerned about the context in which a database lives let alone know what IT auditors would be looking for. I mean, the role I play doesn't seem to have any technical boundaries because, again, anything that can impact the application (be it SAN, OS, network, presentation layer, security, hardware, maybe even Sun spots...) is of concern to me. On the other hand, a DBA without an understanding of the demands put on developer/applications people is a problem, too. Or maybe I needed to whine a bit because I've been up at 2am and 5am a couple of days in a row.

If - this is no longer a choice - you could choose Solaris on Intel, you would get so much bang for the buck that nothing could compete with it.

Re: So, What is a 'Production DBA'?
Hello Dennis My path: Computer operator, duveloper, system programmer, DBA. About developers: they do not see the whole picture, do not understand limitations etc.. I had a call from the guy who is charge of a project. The database creates about 10 MB of archive logs every 3-4 minutes, and is on remote site. He come over to discuss the possibility of implementing a stand by database at our main site. When I asked him the bank width to the remote site he told me: fast, 256KBps. A simple calculation was enough to explain to him that he creates much more data then the pipe line can carry. Boy was he suprised. Yechiel Adar Mehish - Original Message - To: Multiple recipients of list ORACLE-L [EMAIL PROTECTED] Sent: Thursday, May 30, 2002 6:51 PM Gene - C'mon ya gotta give us more details. I have heard that most DBAs either come from developers or sys admins, but I can't recall a former sys admin, or maybe they just didn't mention it. I am curious about your observations on the best and worst qualities of each variety. I feel that a former developer might make a better development DBA because he/she might understand things from the developer's perspective. I could see where it might take a developer turned production DBA awhile to understand a systems perspective. If the developer only created code on a PC, it might take awhile to really get a system-wide perspective (or never). Maybe you'll give me a better appreciation for my sys admin. Dennis Williams DBA Lifetouch, Inc. [EMAIL PROTECTED] -Original Message- Sent: Thursday, May 30, 2002 11:11 AM To: Multiple recipients of list ORACLE-L Actually some of the worst DBA's come from the development track. IMHO, the best DBAs are from the systems world :). Of course this doesn't mean all systems ppl make good dba's or all developers make bad dba's. This is only from my experience. Gene *Let the Wars begin, NOT* [EMAIL PROTECTED] 05/30/02 11:08AM I feel that it is hard to draw the lines between Application and Production DBA's. For example where would you place the DBA that maintains SAP? Without the application knowledge he/she/it wouldn't get very far. Also I have been wondering something and this thread seems a good place to ask. Is there a historical feud between DBA's and Developers? Coming from a consulting/software house I find some of the comments funny but can't believe that there is that quantity of bad developers. Most of the DBA's we deal with have come up through the ranks and started as developers. From: Ron Rogers [EMAIL PROTECTED] Reply-To: [EMAIL PROTECTED] To: Multiple recipients of list ORACLE-L [EMAIL PROTECTED] Subject: Re: So, What is a 'Production DBA'? Date: Thu, 30 May 2002 04:48:29 -0800 Rachel, I agree with your short list of the areas of responsibilities but I would change the word application to development. An application DBA, from the people I have talked to, is quite busy performing the upgrades and patches that accompany the Oracle Applications. The applications database generally has many, many tables, triggers and constraints and is constantly the target for upgrades and patches from Oracle. It is a time consuming task as the majority of the different applications (financial, HR, Purchase Order, etc) have hooks into each different package and are so intertwined that any small fix in one involves patches for the others. There are only a few user defined tables as each package has their own named tables that are partially shared between packages. There is very little if any work you can do on the application code because it is so intertwined and customized when it is installed. Any upgrades require that the customization be reworked to make it fit into the new version of the application package. It takes a longer time to install than a standard database, on the magnitude of days, and requires a dedicated and investigative mind set to maintain. To the list you created I would add: Help desk call recipient, network support, client support, software and hardware evaluation, whipping post, IT team member (possibly team leader), self driven, office coffee maker, consumer of various liquids. Ron ROR mª¿ªm [EMAIL PROTECTED] 05/29/02 04:50PM that's not a bad definition :) seriously, everyone will have their own definition, mine is: production dba -- responsible for all databases that are considered production. this includes but is not limited to: backups recovery testing contingency testing production performance tuning (should mostly be database tuning as SQL really should be tuned at the development stage, with information passed back from the production DBA) documentation of all procedures space management on production systems, including capacity planning and projection of growth change management monitoring external data loads into production database health checks on production database application dba -- responsible for all databases in which developers have access.
