Linux: Updating kernel parameters on Linux
DB2® automatically increases interprocess communication (IPC) kernel parameter values to the preferred settings.
About this task
Procedure
- Issue the ipcs -l command to list the parameter values.
- Analyze the results to determine whether any changes are required for your system. If changes are required, you can set the parameter in the /etc/sysctl.conf file. The parameter value is applied when the system starts.
What to do next
For Red Hat Enterprise Linux 6 (RHEL6), you must set the kernel.shmmax parameter in the /etc/sysctl.conf file before automatically starting the Tivoli® Storage Manager server on system startup.
