Answer 1

Hi,
Now I'm just thinking with U because error 500 can be result of different reasons. I think (I'm not sure)at this situation it has to do with java version.
AIX 5.3 has java version 1.4.2. .
Would U like to go $ORACLE_HOME\jdk\jre\bin\ then just type ./java -full version or java version.
Which result U 'll get.
also type in which java
moreover can U give me the output of the env command.
the last step before U start any as process just do the following
ps -ef | grep (owner of your as)
if U 'll find any process just kill it kill -15 process id if it does not help then hard kill with -9
try to set your environement variable well then start your opmn components again per-process to see which process is going wrong.
Let me know,
Regards
