If you see "Out of memory" errors or are using the server at high capacity, increase
the amount of system memory that is available to the server.
About this task
For servers that are running as a service on Windows, see the following technote: http://www-01.ibm.com/support/docview.wss?uid=swg21698228.
Procedure
To increase the memory for the server on Windows for a non-service installation, or on Linux or UNIX systems, follow these
steps:
- Stop the server.
- In the bin/set_env.cmd file (Windows) or
bin/set_env file (Linux and UNIX), increase the memory in the
JAVA_OPTS parameter. For example, the current file might have a line that begins with the following
code:
JAVA_OPTS="-Xmx2048m
To increase the memory, change the
parameter that begins with the code -Xmx. For example, to increase the
memory to 4 GB, use the following value: -Xmx4096m. Be sure to include
the "m" at the end of the parameter.
- Save the file and restart the server.
