Linux kernel parameter requirements

To avoid addNode and importWasprofile problems, the Linux ulimit default number of open files needs to be increased.

Use the ulimit -n command to check the current limit. If required, change the ulimit number for open files. The appropriate ulimit command (for example, ulimit -n 8192) can be added to the shell profile scripts (for example, .bashrc or /etc/profile.local).

The open files limit requirement for IBM WebSphere Application Server (WAS) Version 8.0 is currently at least 8192.

For further details or if any other kernel parameters need to be changed, see:
