Re: CKPT REQ - Blocked:CKPT

This means that the instance is waiting on a CHECKPOINT to complete. From
the info..it looks like an HDR pair where the Primary is waiting for the
Checkpoint to complete.
check the onstat -u output and look for flags -X- on any of the sessions,
which means this session is in a critical section of the code and the
engine is waiting on that session to finish its work and then complete the
checkpoint ...
Since, its HDR another scenario could be that the primary is waiting on the
secondary to finish its checkpoint as with checkpoints the
primary-secondary pair sync up. In this situation, I think u better check
up your network status as well ...
