--------
The replica IMM objects are not created after opening a checkpoint in following
scenario:
1. Open a checkpoint with flag SA_CKPT_CHECKPOINT_CREATE
2. Unlink the checkpoint ( the checkpoint is still being used)
3. Open a checkpoint with flag SA_CKPT_CHECKPOINT_CREATE with same name as the
one in 1.
After step 3. although the checkpoint is opened successfully, the replica IMM
objects
are not created.
The problem happens because the CPD does not delete relating nodes from
ckpt_reploc_tree
when it unlinks the checkpoint in step 2.
Solution:
---------
The solution is to remove replica location node of that checkpoint from the
ckpt_reploc_tree
when unlinking the checkpoint.
