Hi,

The logic should be like this

1. tablespace begin backup 1a. archive log current
2. suspend database (or sleep)
3. EMC synchronized standard volume and bcv
4. after all mount point (datafile) synchronized EMC split 4a. after EMC split you can mount your bcv to another host and then do the media backup. while you can continue step 5
5. resume database
6. tablespace end backup

Hello,

We are on IBM AIX 4.3.3 with EMC and BCVs. Our Unix admin has setup the backups for the database in following sequence to do the Hot backup.

1. Put all tablespaces in the database in Hot backup mode
2. Sleep 5
3. Put all the tablespaces back into normal mode
4. Split the BCV's
5. Mount on another machine and backed up from it.

What I am concerned is with step 4. Split BCV's should be done at step 2 instead of step 4.
According to our Unix Admin, EMC takes care of consistency and there is no need for any concern. As per him the split is instant split and EMC guarantees consistency.

What do you all think. What is the recommended procedure.

TIA, Nate
