Verifying Tuning Settings

After rebooting the ACSLS server using the reboot -p command, verify your tuning parameter changes.

To verify operating system tuning settings:

  1. Login in as user root.
  2. Change user to acsss using the command su - acsss.
  3. Perform Soft and Hard limit checks using the following commands:
    ulimit -aS
    ulimit -aH 
    
  4. Change back to user root using the command exit.
  5. Change user to acsdb using the command su - acsdb.
  6. Perform Soft and Hard limit checks using the following commands:
    ulimit -aS
    ulimit -aH
