11i Forms Load-Balancing Using JServ

I ran into an 11i E-Business Suite instance which is using Apache/JServ to do forms load-balancing. Here is quick sketch of the instance architecture, a brief overview on how forms load-balancing happens in above architecture, and me more technical details — basically, the XML tags in the Context XML file in APPL_TOP that need to be edited.

Alex Gorbachev at COLLABORATE 08

I guess I have only one and a half posts about COLLABORATE 08 this year. It’s a bit unfortunate that I couldn’t make the whole conference, but only last day-and-a-half. In addition, I’ve been speaking at the two lasts slots of the conference so it’s been quite busy for me. I hope this one long blog post will be accepted in place of several smaller ones.

DBD::Oracle 1.21 Released

The latest release of DBD::Oracle is now ready and can be found at: CPAN DBD::Oracle. It is a Perl module that works with the DBI module to provide access to Oracle databases. The release has been fully tested with the latest version of DBI (1.601). I also included a list of the changes and/or fixes in this release.

Enable JServ Logging Without Bouncing Apache

It is quite common for Oracle Tech support, while troubleshooting any 11i E-Business Suite Self Service Applications (SSWA) related error messages, to ask to enable debug logging in JServ configuration files. The procedure we followed here saved us a complete bounce of Apache, but unfortunately, for changes in jserv.conf to take effect, we still need a complete Apache bounce. This trick will only work for files jserv.properties, forms.properties, viewer4i.properties, and xmlsvcs.properties.

Arrived at COLLABORATE 08

I’m at Collaborate 08 in Denver right now.My presentation, Oracle 11g New Features Out of the Box, was originally scheduled on Thursday at 9:45 AM but due to participation in the speaker panel ,”To RAC or Not To RAC: What’s Best for HA?”, it was rescheduled to today, Wednesday, at 4:30 PM. I’m off to the Carol Dacko’s presentation about DBMS_XPLAN now and looking forward to show up at the RAC SIG Birds of a Feather later today. Stay tuned – more to come…

MySQL Plug-in for Oracle Grid Control Announced, Released

Reading PlanetMySQL today, I discovered that Alex Gorbachev’s announcement that he has released the first public beta of his Oracle Grid Control plugin for MySQL was not aggregated! Knowing that my feed is aggregated, and not willing to let this news and this amazing work go unnoticed by the MySQL community during the conference (I am at MySQLConf listening to Amazon.com’s CTO speak right now!) you can access the update here.

Recent Spike Report from v$active_session_history (ASH)

sec p, dsk p, gets p, rows p, cpu p — these are average statistics for the query being executed. This should give you a quick overview of whether the query is a big query, a small query, a CPU-intensive or a disk I/O-intensive query. Be careful: since the query was introduced to the shared pool, those columns are averages, and therefore could be misleading. These are all per execution stats, so sec p represents the number of seconds on average it took to execute the query.

MySQL Plug-in 0.42 for Oracle Grid Control: First Beta Released

has finally happened! The first public release of the MySQL plug-in for Oracle Enterprise Manager 10g Grid Control is out. In the last few months, more and more people showed interest in the potential plug-in, and even few guys from Oracle contacted me independently of each other with their own reasons to have a MySQL plug-in available. This interest accelerated the fermentation of thoughts in my brain, and I got down to work. Pythian generously sponsored my development time. Here are the details. The first release version is 0.42 because that’s obviously the perfect number to start something good.
