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.

The Ingres Vultures Descend

If Ingres thinks they can win customers over by swooping in when a controversy is happening, they are way more evil than I would ever have guessed. It’s not good business practice to do this kind of thing — it is cold, calculated, uncalled for, and just plain wrong. There is so much else that bothered me about the e-mail I received, so I will just copy it here for full context for readers.

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.

Social applications are compelling.

Liveblogging: Who is the Dick on My Site?

How do you prove to a website who you are? It’s not what you give to the site, but what the site knows about you! If you have a good eBay rating, can you take that over to Craigslist? What we want in Identity 2.0 is a way to make identity user-centric, not site-centric, so a person can move their identity around. How do we solve this you ask.

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.
