Do ASM Rebalance Operations Run in Serial or Parallel?
976474Nov 27 2012 — edited Dec 10 2012Background: We are migrating a lot of databases from one SAN appliance to another. We are doing this by adding new disks from the new SAN appliance to the existing diskgroups, rebalancing, removing the old disks from the diskgroups, and then rebalancing again.
Question: If I execute two ALTER commands with the same power on 2 or more separate diskgroups, do both operations start executing right away? Or do they queue up and execute one after another?
I ask because we would like to queue up several re-balances so we don't have DBAs watching status bars all day.
