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:
