Hi,

I'm running Oracle10g on RHEL 4. For some reason my ons.log files are getting huge (1.5G) and then they fill up the disk and I can't log in to Oracle. What could cause this? And where can i change the size?

thank you

From
Enterprise Manager Grid Control Installation and Basic Configuration
Chapter 11 Upgrading Enterprise Manager Grid Control

Quote:

There may be instances where the Enterprise Manager Using a New database installation and its subsequent upgrade encounters an abnormal growth of the ons.log. This can potentially take up a lot of disk space relatively quickly.

In such circumstances, you must check whether or not the ons.log contains repeated messages such as the following:

Local connection 0,127.0.0.1,6100 missing form factor

If such an error message is observed in the ons.log, perform the following steps:

1/ In the Database Oracle home, rename the $ORACLE_HOME/opmn/conf/ons.config file (in order for the Listener not to find the database to sue it). For example,

cd $ORACLE_HOME/opmn/conf
mv ons.config ons.config.orig

2/ Restart the Listener.

Regards
Michel

I have now found a new issue. If I give the above mentioned command (i.e. renaming the ons.conf file), then I can't start http server. It is looking for the old file name:

[oracle@rh-staging conf]$ /opt/app/oracle/product/10.2.0/http_1/opmn/bin/opmnctl start
open failed for /opt/app/oracle/product/10.2.0/http_1/opmn/conf/ons.conf (No such file or directory)
opmnctl: opmn start failed
