How to resolve java.lang.OutOfMemory errors in Oracle Application Server

After running Oracle Application Server for about a year, we started getting a java.lang.OutOfMemory error after deploying a new EAR file.  The error was due to the size of the application growing to large.

To resolve the error, open up Oracle Enterprise Manager in your web browser (Default is http://servername:1810).

Do the following:

1. Under System Components, click on the OC4J container that is having the issue.
2. Click on Administration
3. Click on Server Properties
4. Under Command Line Options / Java Options add -Xmx512m at the end.
5. Click on Apply
6. Click on OK
7. Try redeploying the EAR file again.
