We are using 11gr2. At yesterday night heavy insert operation is done. Due to which our archival dest was full, I extended mount point reffering to archive dest.
So now that problem is solved. We have physical standby with max performance mode, now the situation is there is a gap of 250 in between DC-DR. MRP process is running, archivelog also transferring from DC to DR but apply rate is slow. Sometimes apply rate is slow and sometimes it becomes less than average. I have already restarted MRP process but GAP is still there. Also, when I have checked on standby archive dest, archives gap is showing but it is automatically resolving and applying but with a very very slow rate.
So what could be the reason and solution?
Can I go for Alter database recover managed standby database disconnect from session parallel 8?
can it require any pre-requistic?
Thanks in advance.
