Siebel on Sun Solaris: More Performance with Less mprotect() Calls

By default each transaction in Siebel CRM application makes a large number of serialized mprotect() calls, which in turn may degrade the performance of Siebel. When the load is very high on Siebel enterprise servers, the mprotect() calls are serialized by the operating system kernel resulting in high number of context switches and low CPU utilization.

If the application exhibits these pathological conditions, performance thus scalability of the application can be improved by reducing the number of mprotect() during run-time with the help of AOM tunable MemProtection=FALSE.

From the command line version of Siebel Server Manager, run:
change param MemProtection=False for comp <component_alias_name> server <siebel_server_name>

where:
component_alias_name is the alias name of the AOM component to be configured, such as SCCObjMgr_enu for the Call Center Object Manager; and

siebel_server_name is the name of the Siebel Server for which the component being configured.

The MemProtection parameter is hidden; and the value of this parameter is TRUE by default.

For more information about this tunable on Solaris platform, check Siebel Performance Tuning Guide Version 7.7 or 8.0 in Siebel Bookshelf.

My First Bug Report in Open Source Arena

.. is against Firefox.

Complete bug report with reproducible steps is at:

378847 – Preserve form and search history as soon as the data is entered

Perhaps I should fix it. It is the right time to start building the Firefox web browser on my own, I guess.

Similarities between {Garfield, [Dilbert}, Seinfeld]

First, the fact: I'm a big fan of Jim Davis' comic strip, Garfield, Scott Adams' comic, Dilbert, and the sitcom Seinfeld.

Garfield Vs Dilbert

Recently I've been reading Dilbert comic strips from mid 90s; and I couldn't help but notice some striking similarities in the way both Jon Arbuckle (Garfield's owner) and Dilbert (Dogbert's owner) crave to get a date or how they ruin their date, when they have one. There are similarities in the sarcastic comments made by Garfield and Dogbert too, toward their owners Jon and Dilbert respectively.

Dilbert Vs Seinfeld

Unlike Dilbert, Seinfeld is too smart to get as many dates as he like; but it appears both Dilbert and Seinfeld follow the same etiquette when they run into the same person more than once in the same day. For instance, in one of the Dilbert strips titled Hallway Etiquette, Scott suggests the following simple three rules, with Dilbert as one of the characters in the comic strip:

1. First hallway meeting of the day: Greet Good Morning / Afternoon / Evening.
   
   
2. Second hallway meeting of the day: Raise your eye-brows and give a tight-lipped smile.
   
   
3. Third hallway meeting of the day (and there after): Sneeze to avoid eye contact, try to hide etc.,

I don't remember the exact Seinfeld episode (there are just too many), but in one of those 176 episodes, Jerry Seinfeld makes similar suggestions to his audience in the opening monologue or to his friends, George Costanza, Elaine Benes and Cosmo Kramer, in the play.

In another Dilbert comic strip, Dilbert and his co-worker asks a lady "When's the baby due?". "Can't a woman go off her diet for one day without getting that question??" replies the irked lady, just like the character Maryedith responds to Kramer's "Are you sure you're not pregnant?" in The Parking Space episode of Seinfeld.

It is a small world - I wonder who inspired whom.

Solaris tip: Retrieving the package name for a file

Q: Given a file name {with absolute path}, how do we retrieve the package name which the file belongs to?

There are at least two simple ways:

1. Look into /var/sadm/install/contents file, or
   
2. Run /usr/sbin/pkgchk with -l, -p as options and the absolute path as argument

eg.,
To find out what package /usr/sbin/fcinfo belongs to:

# grep /usr/sbin/fcinfo /var/sadm/install/contents | awk '{ print $10 }' | sort -u

SUNWfcprt

Or

# pkgchk -l -p /usr/sbin/fcinfo

Pathname: /usr/sbin/fcinfo
Type: regular file
Expected mode: 0555
Expected owner: root
Expected group: bin
Expected file size (bytes): 50784
Expected sum(1) of contents: 49262
Expected last modification: Dec 04 05:22:58 2006
Referenced by the following packages:
        SUNWfcprt      
Current status: installed

Upgrading Oracle E-Business Suite 11.5.10 to CU2

Some notes I collected from the exercise of upgrading Oracle E-Business Suite 11.5.10 to 11.5.10 CU2^*, on Sun Solaris:

1. [Middle-tier] Apply patch 4318672 on all application server nodes
   
   
   • Enable maintenance mode by running adadmin.
     
     
   • Apply patch 4318672 with the help of adpatch tool.
     
     
   • Carefully read README.txt of 4318672, and run Technology Stack Validation tool in both middle- and db-tiers.
     
     Note:
     
     
     • Set PARALLEL_MAX_SERVERS parameter to the default value returned by show parameter cpu_count. For example, if the database is running on a SunFire T2000 server, set PARALLEL_MAX_SERVERS to 32.
       
       
     • [DB-tier] When prompted for applications context file, supply the output of echo $CONTEXT_FILE environment variable.
       
       
     • After running Technology Stack Validation tool, the generated html reports from middle- and db-tiers should have an 'ALLPASS' status. Otherwise, fix the errors and re-run the TSV tool until it achieves ALLPASS status.
   
   
2. [Middle-tier] Apply patch 4229931 on all application server nodes
   
   
   • Apply patch 4229931 with the help of adpatch tool.
     
     Location of adpatch log file: $APPL_TOP/admin/<DBInstanceName>/log/adrelink.log.
   
   
3. [Concurrent Processing node] Apply patch 4297568
   
   
   • Enable maintenance mode by running adadmin tool, if concurrent managers are not running on the same machine where all application server processes are running; then apply patch 4297568 by following the special instructions posted in README.txt file.
     
     Note:
     
     • Do NOT use adpatch tool to apply this patch, 4297568. Read the instructions of README.txt.
       
       
     • Without this patch, 4297568, CU2 maintenance patch, 3480000, may fail with error messages like:

       ld: fatal: file  /ebiz/visappl/sht/11.5.0/lib/ilog/5.1/libcplex8.a: 
       open failed: No such file or directory
       ld: fatal: File processing errors. No output written to /ebiz/visappl/demoappl/mst/11.5.0/bin/MSTCPP

       See Metalink document 311635.1 for more.
       
       
     • Some executables need to be re-linked as part of this step. Re-linking can be done in two ways:
       
       
       1. Using adadmin tool.
          
          Navigation: Maintain Applications Files -> Relink Applications Programs. This step re-links all the executables of the application.
          
          
       2. To re-link one or more applications' executable programs, run adrelink from the operating system shell:
          
          Syntax:
          adrelink force=y "<product> <module>"
          
          eg., To re-link MSO: MSONEW, run:
          
          adrelink force=y "MSO MSONEW"
          
          Shutdown all concurrent managers before running adrelink.
     
     
     
   • Disable maintenance mode by running adadmin, if concurrent managers are not running on the same machine where all application server processes are running.
   
   
4. [Middle-tier] Apply release 11.5.10.2 maintenance pack, 3480000
   
   
   • Apply patchset, 4712852, with the help of adpatch tool.
     
     
   • Apply release 11.5.10.2 maintenance pack, 3480000, with the help of adpatch tool. Spare some time to read Metalink document 316365.1, before applying the maintenance pack.
     
     Note:
     
     
     • Stop all application server services including concurrent managers before running adpatch on 3480000 (CU2 maintenance pack). Failure to do so may result in the following error(s):

       ATTENTION: All workers either have failed or are waiting:
               FAILED: file afcmgr.odf on worker 1
       ATTENTION: please fix the above failed worker(s) so the manager can continue

       When such an error occurs, do the following:
       
       
       • Open up another shell and shutdown all services by running adstpall stop apps/apps command.
         
         
       • Run: adctrl
         
         • Check: 1) Show Worker Status.
           
         • 2) Tell worker to restart a failed job
         
         After this step adpatch resumes automatically.
         
         
       • adworker log file(s) default location: $APPL_TOP/admin/<DBInstanceName>/log.
     
     
   • Troubleshooting:
     
     
     • ERROR: file azstrctall.ldt on worker 1
       
       Follow the instructions of Metalink document '331284.1 Applying 3480000 Patch --- azstrctall.ldt failed --- ORA-20001: The specified api_code does not exist'.
       
       
     • FAILED: file AsgRunInst.class on worker 1
       
       Follow the instructions of Metalink document 270156.1. In short, skip the failed thread with an hidden option {of adctrl} : 8) Skip & Restart for worker thread 1. Run the failed thread manually, later.
   
   
   
5. [Middle-tier] Disable maintenance mode by running adadmin
