Hello, I am trying to configure LUN to LUN replication with oracle 12c. After multiple failed attempts and no help from EMC support I am hoping someone here has been able to make this work.
Trying to setup EMC Recoverpoint lun to lun replication with Oracle 12c RAC 2 node cluster to Disaster Recovery RAC one node cluster using ASM
We get Oracle up and working in the single node DR env and turn on recoverypoint. Once the replication is completed we turn the one node cluster back to read/write and when we try to sqlplus Oracle gives us the error:
CRS-4535: Cannot communicate with Cluster Ready Services
CRS-4530: Communications failure contacting Cluster Synchronization Services daemon
CRS-4534: Cannot communicate with Event Manager
We reinstalled Oracle and the same thing happens once the luns have replicated.
I believe the issue is with storage. But I cannot place my finger on it.
-What data and configurations need to be replicated for Oracle?
-What data and configurations need to NOT be replicated for Oracle?
-After a fail over through recoverpoint what are the steps to getting Oracle up and running?
- Are there scripts that need to be run to mount the LUNS or VOTING disks?
- Do we need to restart Oracle or CRS or any services?
- Or when it fails over to DR should we be able to just log in without any changes done to Oracle?
Do we need to put the VOTE disks onto a LUN that is not being replicated?, what about the VOL disks?
-Recoverpoint 4.0.SP2(m.24)
-RHEL 6.8
-Oracle 12c
-This was working previously with Oracle 11g
Any help would be much appreciated!
