oacore OC4J logfile application.log

$LOG_HOME/ora/10.1.3/j2ee/oacore/oacore_default_group_1/application.log got 8GB in size due to 10.1.3.5.0 Container error entries (bug 10126440 ? ).

$ find . -type f -size +500000 -exec ls -alh {} \;

./EBSP/inst/apps/EBSP_note1p/logs/ora/10.1.3/j2ee/oacore/oacore_default_group_1/application.log
I tried to rename application.log, but oacore process kept writing entries to the re-named file. I also deleted it and found oacore process did not create a new one while the space was still getting filled up and "find" command did not find which file it write the log entries to.

The fix is to re-name/delete application.log file and then bounce OACORE process which will create a new application.log file.

$ ps -ef | grep oacore| wc -l
4
(in my another instance, it gets 6)
