Updating the CSS misscount setting

Oracle RAC requires the CSS misscount value to be set to 600 seconds with vendor clusterware.

Check the current CSS misscount setting:

# $GRID_HOME/bin/crsctl get css misscount

If the current CSS misscount setting is not set to 600 seconds, update the setting as described in the following procedure.

To update the CSS misscount setting

  1. Shut down Oracle Clusterware/Grid Infrastructure on all but one node.
  2. Log in as the root user on the active node and set the CSS misscount interval to 600 seconds:
    # $GRID_HOME/bin/crsctl set css misscount 600
  3. Restart Oracle Clusterware/Grid Infrastructure.
  4. Verify that the setting is updated:
    # $GRID_HOME/bin/crsctl get css misscount
