Re: jvm_statistics.log

Hello Tanish,

 

Have a look into below document, it will explain about common log files in BAC:

 

http://support.openview.hp.com/selfsolve/document/KM193212

 

~~~~~~~~~~~~~

- jvm*
This is the Java Virtual Machine log. The jvm_statistics.log file contains information on Heap usage. Look at this file if an "Out of memory" error is seen in another log file such as topaz_all.ejb.log.
