Existing connections with Priority Group Activation - minimizing client impact, timeouts, etc.
Hi, we're using PGA for an active/standby config, with an either/or relationship between the groups (activation set to < 1 server).
We're finding that when the higher priority group is reactivated, existing connections to the servers in the lower priority group continue to be used for some time.
What are the settings that affect this? Slow ramp is involved, based on some of the answers here - persistence method? Action on service down (when a priority group is deactivated, does "action on service down" come into play?)? Other? And how does each setting come into play with PGA group activation/deactivation?
What settings would be required if we wanted as immediate as possible a switch back to the higher priority servers, potentially even immediate as soon as the group becomes available?
These questions are touched on by various questions/answers here, but no clear picture emerges (at least for me). Can point to a KB or guide that nails it all down cleanly?
