Hi Asura2006 , 
The default behavior of Priority group Activation is when the Backup PG activated it handles your connections , but when higher PG is returned UP and active again , all comming new connections is handled by "main" PGA and the Backup PG handles only Active connections till it completes. 
I see this is a good behavior to be done by PGAs and this is the default. 


If you see that the new connections don’t be handled by "main" PG when it became actve , check if you enable " manual resume " option under assigned monitor configuration. 

> Do you want to transfer active connections to be handled by "main"PG when it became available again ?
specify more please in this section.

Hello,

the problem here is that i want primary PGA to handle ALL the connections after 2-3 minutes from beeing back up. The connections on backup PGA should be closed so that they will be all on primary PGA.

 

Manual resume on monitor doesn't really help me because it means that each time the primary PGA goes down and up ill have to manually select "enabled" to every node with this monitor.
