Shalom,

A number of possible causes, from most likely to leasst likely:

1) Required java patches are not installed. Java is one of those apps that will install without required patches.
2) Java version itself was replaced due to this problem. Its pretty easy to update java from http://www.hp.com/go/java
3) Problems with OS patching not being done properly for oas10g. This is a common problem, this app checks come critical patches at install but the checklist is not complete.

I've done 1 oas 10g install since coming to Israel and avoided all of these problems by making sure all of the above three items were fixed prior to starting the install.

4) oas itself has a problem that requires a patch.
5) Not enough system memory is available. Oracle's minimums are not enough for even a small system.

You haven't mention those processes here and neither the environment details. But looking at the another thread you created a while ago, help to reply.

The jave process looks like a part of Oracel Reports. What is the size of the report server cache size set in
$ORACLE_HOME/reports/conf/repserver.conf ?

It should not be 0 or have negative value.

Hi,

Pl. mention those processes, also make sure
if u r doing a proper shutdown ( because
oracle AS requires shutdown of processes in proper
sequence.

hi,

do you still have the output from:

ps -ef|grep

this can help shed some more lights on the problem.

We recently had a similar problem which turned out to be related to a reports server issue. We had too many reports engines declared....

kind regards

hi,

this a rather difficult question. There may be some report server parameters that have been improperly tuned. There may also be some kernel parameters not well set as well. There may be java patches missing. The list is long.

I would suggest that you log a Service Request on Metalink. This is what we did for our numerous reports server problems that was effectively solved by Metalink engineers.

good luck!
