Increasing the Java Heap Size on Oracle WebLogic Web Servers

When using an Oracle WebLogic web server, you increase the JVM heap size in the setenv.cmd file.

To increase the Java heap size on an Oracle WebLogic web server:

  1. Use a text editor to open the setenv.cmd file.

    The file is located via the following path: .

    <PIA_HOME>\webserv\peoplesoft\bin

  2. Locate the SET JAVA_OPTIONS parameter.

  3. Change or add the –XmxZZm parameter, where ZZ equals the amount of RAM, in MB, to allocate.

    The following example shows the parameter set to a maximum of 128 MB.

    SET JAVA_OPTIONS=-hotspot -ms1m -mx128m

  4. Save the changes.

When you run the Simple Post utility, you must specify the maximum Java heap size that you specified here. For example, if you set the JAVA_OPTIONS parameter in the setenv.cmd file to 128 MB, when invoking the Simple Post utility you must add the following argument to the command line:

-Xmx128m
