If you check out the “Butterfly Effect” on Wikipedia, you’ll find a rather interesting reference to, “sensitive dependence on initial conditions in chaos theory.” Fascinating use of phrase that probably doesn’t mean much to normal people until it happens to you. I could give you lots of theoretical examples, but perhaps a real-life one will make more sense.

Last week, a client of Pythian’s came to us with an environment that had recently been upgraded from Oracle Applications 11.5.9 to 11.5.10. In the past, Pythian has not supported the Oracle Applications environment for this client, but that is one of the strengths of Pythian — we have DBAs with a broad range of knowledge and expertise to support just about anything thrown at us. The emails from the client users suggested a myriad of performance issues, ranging from forms being slow to POs not being processed.

I can sympathize with the client, as I used to be one (that’s how I came to work for Pythian — but it’s also another story that I shall relate sometime). Performance issues in Applications can be tricky at best, as there are so many diverse factors to consider. Not having supported Oracle Apps for this client before means that we were starting with a clean slate and just looking for things out of the ordinary based on experience with other clients, sort of “searching for a needle in a haystack.”

The first thing was to just login to the application and take a quick walk about the area — did anything stand out? What was the first impression? It took a bit of time to get connected initially, but the forms seemed to come up without any undue issues. One of the early comments in the email we had received mentioned that POs weren’t being processed by the workflows. Maybe a trip to “View Requests” was in order . . .

I recently implemented OID/SSO with E-Business Suite 11.5.10 CU2, and experienced some issues after the entire setup went smoothly. I hope this note might help others troubleshoot, as it took me a while to figure out the root cause of the problem.

Facts

1. E-Business Suite Version 11.5.10 CU2
2. 10G Version 10.1.2.2

You have done the install and everything went fine. After the bounce you see the following:

1. Login from a remote location
2. Navigate to Administrator System –> Security –> User –> create
3. Enter username and save. The error occurs.

Unable to call fnd_ldap_wrapper.create_user due to the following reason:
ORA-20001: Unable to call fnd_ldap_wrapper.create_user due to the following reason:
An unexpected error occured . Please contact System Administrator..(USER_NAME=OIDTEST)

My name is Vasu Balla, and I’ve been with Pythian for about four months now. I have worked on Oracle E-Business Suite instances for over five years, and I’ve never had a moment where I felt bored.

I am constantly challenged with new technologies and new issues, and my Pythian team’s clients continue to present interesting issues. The most difficult are the ones that are very intermittent or not easily reproducible. If you try to get answers for these kind of issues from Oracle Tech Support by opening a SR, your chances are next to none. Our team recently encountered an issue a client had had with Oracle Configurator for two years. They had followed up with Oracle Tech Support for over a year and had eventually learned just to live with the problem. When Pythian came in, we were shocked to learn the history of the problem. It turned out to be one of the most exciting problems we’ve resolved.

I am new to blogging, but quite experienced in reading blog posts. My Google Reader collects over 100 articles per day, mostly around my interests, which are:

• Oracle 11i E-Business Suite Advanced topologies
  • Hardware Load Balancing
  • DNS based Load Balancing
  • Jserv Load Balancing
• Oracle 11i SSL Implementation at Load balancer level
• Forms load balancing using Jserv + forms servlet mode
• Oracle Concurrent Managers PCP setup
• Oracle 11i Apps with RAC configuration

Signing off, now — with a promise to post some interesting stuff on topics such as these. Stay tuned.
