Re: Streams and realtime apply

For me configuration looks good and seems to be quiet strange..

When you start MRP is there any informational messages? The MRP status shows whether it started with real time apply or not. If you haven't started MRP as "alter database recover managed standby database using current logfile disconnect from session", then i would suggest to start and see and share your observations?

And can you get output for below query too? SQL> select recovery_mode from v$archive_dest_status where recovery_mode !='IDLE'; What about the size of the ORL on Primary? How many redo log groups on Primary?
Also add block#, blocks in the same query you have used "select PROCESS, STATUS, THREAD#, SEQUENCE# from v$managed_standby;"

Thank you.
