Execute User-Defined Scripts from High Availability Properties

You can execute scripts to run in HA scenarios from the following property groups:

• Network Traffic Redirection
  • Active to Standby Redirection -- Turn On this property to execute a script that runs on the active server, if it is available, to redirect users to the standby host, or to release network resources on the active host.
  • Standby to Active Redirection -- Turn On this property to execute a script that runs on the standby server, to redirect users to the active server.
  • Identify Network Traffic Redirection -- Turn On this property to execute a script that determines which server is active. If the script returns 0, the host it was executed from is considered to be the active server. If the script returns a non-zero value, that host is considered inactive.
• Is Alive, Check Method
  • Check Script on Active Host -- this script runs on the active server during every Is Alive heartbeat to verify that the server is available to users.
  • Check Script on Standby Host -- this script runs on the standby server during every Is Alive heartbeat to verify that the server is available to users.
  • Start DB/Start Application/Add Shares -- When set to On, the script augments or replaces the start of DB services and applications, or enables folder sharing. The action defined occurs during the scenario run process on the active host, or during a switchover on the standby host.
  • Stop DB/Stop Application/Remove Shares -- When set to On, the script augments or replaces the stopping of DB services and applications, or disables folder sharing. The action defined occurs during the scenario run process on the standby host, or during a switchover on the active host.
• Action Upon Success -- When set to On, the script executes its defined actions after a successful switchover.
