Hello,

are you aware of the DMQ synchronisation for dialog data? It’s not replicated everything, but certainly a way to seed the dialog information after a restart.

Another way is of course the usual shared database, just keep in mind that you need to configure the dialog module (hash table “step” variables”) to properly work.

Cheers,

Henning

Subject: [SR-Users] Dialog DMQ state after restart

Does the dialog module do anything similar to the htable dmq_init_sync behavior?

The scenario is restarting the offline member of an HA pair after modifying the script. We're unsure of the state of the replicated dialogs post-restart. Will the standby become aware of the dialogs prior to the restart? In other words, do we need to wait until the pre-restart calls end before we can safely failover?
