@@majojepan9 Hi, Yes, DB sessions will be disconnected, however, if application can reconnect automatically to the new db without letting users feeling this you may consider it as no disconnecting. Mainly I consider it as interruption.
Thats depends on connection type If it is tnsnames you may change it or configure it to cover both If network nat or dns in the middle you may change there
Hi, On doing switchover in 19c , it completes successfully but if I do show configuration afterwards , it gives the same apply lag error which you got. In your case it got resolved in some time, but in my case it doesn't go away automatically , it persists. Please suggest what could be the issue.
Hi Check the logs for the details, seems that missing configuration on the standby . Start with connecting from standby server to the main server db and reverse.
