Last published : Sep 18, 2026
On nodes with heavy load, the CSSD agent attempts to check the status of Oracle Clusterware till it reaches theFaultOnMonitorTimeouts value. However, Oracle Clusterware fails to respond and the CSSD agent forcibly stops Oracle Clusterware. To prevent the CSSD agent from forcibly stopping Oracle Clusterware, set the value of the FaultOnMonitorTimeouts attribute to 0 and use the AlertOnMonitorTimeouts attribute as described in the following procedure.
Perform the following steps to prevent the CSSD agent from forcibly stopping Oracle Clusterware:
  1. Change the permission on the VCS configuration file to read-write mode:
    \# haconf -makerw
    1. Set the AlertOnMonitorTimeouts attribute value to 4 for the CSSD resource:
    \# hatype -display CSSD | grep AlertOnMonitorTimeouts
    CSSD  AlertOnMonitorTimeouts 0
    \# hares -override cssd_resname AlertOnMonitorTimeouts
    \# hatype -modify CSSD AlertOnMonitorTimeouts 4
  2. Set the FaultOnMonitorTimeouts attribute value to 0 for the CSSD resource:
    \# hatype -display CSSD | grep FaultOnMonitorTimeouts
    CSSD  FaultOnMonitorTimeouts 4
    \# hares -override cssd_resname FaultOnMonitorTimeouts
    \# hatype -modify CSSD FaultOnMonitorTimeouts 0
    1. Verify the AlertOnMonitorTimeouts and FaultOnMonitorTimeouts settings:
    \# hatype -display CSSD | egrep \
    "AlertOnMonitorTimeouts|FaultOnMonitorTimeouts"
    CSSD  AlertOnMonitorTimeouts 4
    CSSD  FaultOnMonitorTimeouts 0
  3. Change the permission on the VCS configuration file to read-only mode:
\# haconf -dump -makero
