Heap Size used by AdJavaWorker

Hi,

I am applying R12.1.2 patchset and seeing performance issue on Server.

Lot of memory and swap is being consumed by AdJavaWorker.I have defined Java Heap size to 128m(Min) to 256 MB(max) in Context file, adovar.env and adovar ref file placed in INST_TOP by defining ADJREOPTS parameter.

But Heap size being used these each Java worker is 1GB. Does anyone have idea from which place AdJavaWorker picks Heap size.

Here is the test case:

$  jps -l
25724 oracle.apps.ad.worker.AdJavaWorker
904 sun.tools.jps.Jps

$ jstat -gc 25724
 S0C    S1C    S0U    S1U      EC       EU        OC         OU       PC     PU    YGC     YGCT    FGC    FGCT     GCT
