Adjusting the Operating System Shared Memory Parameters

No special steps are necessary to configure for shared memory, however, you can modify the global ulimit information in /etc/security/limits with the following, in case the default hard limits for file sizes (fsize) and numbers of files (nofiles) may be too low:

• ulimit -d – displays current process execution memory limits
• ulimit -d unlimited – sets process execution memory limits to unlimited

You can also edit /etc/security/limits by changing the default data value to “-1”:

default: 
    ...
    data = -1 
    ...
