1 such param is  -verbose:gc and  -Xloggc:verbosegc.log . The Xloggc parame= ter is simplay=20 a filename where the GC information is written=20 to.
 
There are some docs on Sun's Java site for interpreting=20 garbage collection information or search=20 Google.
 
 
 
 
 

Thanks!

Subject: Monitoring memory usage by Java=20 process

does anyone know a way to identify how momory is used by a java= =20 process? On one of our servers, a process keeps hogging memory to a stage w= here=20 we kill it. Whereas on a similar instance, it is well behaved.

Since= it=20 is java I am not on java cluetrain. The databases are=20 9204.
