and I am getting low shared memory errors that is why I want to fix this in the kernel settings. It says in the guide.
"When instances are started, if an interprocess communication (IPC) kernel parameter is below the enforced minimum value, the database manager updates it to enforced minimum value. The IPC kernel parameter values changed when a DB2® instance is started do not persist when the system is rebooted. After a reboot, kernel settings might be lower than the enforced values until a DB2 instance is started. By adjusting any kernel parameter settings, the database manger prevents unnecessary resource errors.
