Adjust maximum resource settings for the operating system

You can change the ulimit settings to avoid running out of file handles, sockets, or memory. If you are receiving error messages related to file handles, sockets, or memory, or if you think there might be a high possibility of this happening, for example if your environment is running multiple instances of IBM WAS:

1. Log in as root.

2. Enter a new ulimit value. For example, to set the maximum number of open file descriptors, use the command:

   ulimit -n value

   The recommended value is 2000.

   Some ulimit settings may affect system stability.

3. Verify that the new ulimit value has been set:

   ulimit -a
