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 to enable debug logging in JServ is to update following line in file $IAS_ORACLE_HOME/Apache/Jserv/etc/jserv.properties from log=false to log=true, and then bounce Apache using:

$ cd $COMMON_TOP/admin/scripts/$CONTEXT_NAME
$ adapcctl.sh stop
$ adapcctl.sh start

After the bounce, we start seeing debug messages in the log file $IAS_ORACLE_HOME/Apache/Jserv/logs/jserv.log.

Please note, the logfile’s and config file’s locations can be different from those mentioned above. In case you have a shared tech stack implemented, replace $IAS_ORACLE_HOME with $CONF_TOP/iAS.

The main problem with this procedure is the bounce of Apache. In cases where the client is not a heavy SSWA user and the issue isn’t affecting a significant number of users, then often we will be asked to wait until off-business hours to do the bounce of Apache. These delays can make your metalink SR hop between different Oracle support offices in different timezones, which can lead to delays in resolution of the issue.

Let’s have quick review of JServ configuration files which are of interest to us. jserv.conf — this is the configuration file of mod_jserv module in Apache. Here’s a snippet from jserv.conf: Read the rest of this entry . . .

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.
