Oracle DR Setup Problems / ORA - 600 /

Dear All,

Recently we have implemented DR(Disaster Recovery setup Using Oracle data guard in 10g, GUI configurations ) in our Production server. The DR setups are based on the Maximum performance with Realtime apply mode.

The configuration went fine and both servers(DR and ) were syncing fine together as well.

But unfortunately, there was a power failure in the DR site(Which is on the other network) and also the UPS also went down after some time, the real problem started here,

Once the DR server was down, after sometime we are not able to login in to the production system, Interestingly, both DB server and application server are running fine. But we are not able to login into server - SAPGUI hangs. There are no such error written in SAP level and but in oracle alert log, we found out ORA 600 error and also connection timed out for placing the archive log(log_destination_2) in the standby server(This is the DR server - And due to power failure, its not able to reach the server for placing the archive log file )

Temporary solution,

If we restart the production server, we are able to work continuously in the production system without any problem.

So, my query is that, what makes the production system hangs if DR server is unavailable and how it work if we restart the instance? Is this the normal procedure in DR setup? or its a bug in the oracle data guard or in the parameter log_archive_dest2?

Looking forward for your answers with your valuable suggestions

For the reference, I am pasting a part of alert log
