Faster Redundancy Restoration After Storage Loss

10.1.19.3 Faster Redundancy Restoration After Storage Loss

Using Oracle Grid Infrastructure 12c Release 2 (12.2), redundancy restoration after storage loss takes less time than in previous releases.

A new REBUILD phase was introduced to the rebalance operation. The REBUILD phase restores redundancy first after storage failure, greatly reducing the risk window within which a secondary failure could occur. A subsequent BALANCE phase restores balance.

Oracle Grid Infrastructure release 12.1.0.2 with DBBP 12.1.0.2.170718 also includes the Oracle ASM REBUILD phase of rebalance.

Note:

In Oracle Grid Infrastructure 12c release 2 (12.2), rebuild is tracked in V$ASM_OPERATION via a separate pass (REBUILD). In Oracle Grid Infrastructure 12c release 1 (12.1), both rebuild and rebalance phases are tracked in the same pass (REBALANCE).
