Goal

The ORA-04030 errors are seen on the Portal log files:

<TIMESTAMP> WLS_PORTAL ERROR] [ http://<HOSTNAME> [tid: userId: ecid: <ECID> APP: portal ERROR: Repository Gateway error: Database Error: ORA=4030 ORA-04030: out of process memory when trying to allocate 16328 bytes (koh-kghu sessi,pl/sql vc2)
<TIMESTAMP> WLS_PORTAL ERROR] [ http://<HOSTNAME> [tid: userId: ecid: <ECID> APP: portal ERROR: Repository Gateway error: Database Error: ORA=4030 ORA-04030: out of process memory when trying to allocate 16328 bytes (koh-kghu sessi,pl/sql vc2)

One of the recommendations was to set the process stack limit to unlimited for the java child process from the WLS_PORTAL managed server process.

The stack for this process was set to unlimted as follows:

oracle <HOSTNAME>(FTEL9i)(59): plimit 22878
22878: /oracle/jdk1.6.0_45/bin/sparcv9/java -server -Xms256m -Xmx512m -XX:Max
...
stack(kbytes) 32768 unlimited
...
oracle <HOSTNAME>(FTEL9i)(60): plimit -s unlimited 22878
oracle <HOSTNAME>(FTEL9i)(61): plimit 22878
22878: /oracle/jdk1.6.0_45/bin/sparcv9/java -server -Xms256m -Xmx512m -XX:Max
...
stack(kbytes) unlimited unlimited
...

However the stack limit gets set to 32768 within minutes of running the plimit command.

Is there any setting in the WLS_PORTAL configuration to permanently assign an unlimited stack to this process?
