In this Document

APPLIES TO:

GOAL

This note outlines the steps to move 12c GIMR (Grid Infrastructure Management Repository) to a different shared storage. 

This procedure will NOT preserve Management Database contents. If necessary, before implementing the procedure, backed up in text format as grid user on any node: 

SOLUTION

1. Stop and disable ora.crf resource.

On each node, as root user:

Do not stop ora.mgmtlsnr or ora.mgmtdb resource or Step 2 will fail with the following:

2. Issue the DBCA command to delete the management database

As Grid User, locate the node that the Management Database is running by executing: 

As Grid User on the node where ora.mgmtdb resource is running execute:

3. Recreate the MGMTDB

3A. For 12.1.0.1 only:

As grid user, on any node execute the following dbca command:

NOTE: It's recommended to set both compatible.asm and compatible.rdbms to 12.1 for the new ASM diskgroup when creating or altering and existing diskgroup. 

Also, this example created the Management Database in a new ASM Diskgroup, to create the database in shared NFS/CFS location:

3B. For 12.1.0.2 only:

a. As Grid User on any node execute the following DBCA command with the desired :

NOTE: It's recommended to set both compatible.asm and compatible.rdbms to 12.1 for the new ASM diskgroup when creating or altering and existing diskgroup.

Ex: CREATE DISKGROUP … ATTRIBUTE 'compatible.rdbms' = '12.1', 'compatible.asm' = '12.1';

The Management Database may be moved to an ASM Diskgroup, in a shared NFS/CFS location with the following command line:

b. Create a PDB within the MGMTDB using DBCA.

As Grid User on any node execute the following DBCA command:

NOTE: The CLUSTER_NAME needs to have any hyphens (“-“) replaced with underscores (“_”)

4. Secure that the Management Database credential:

As Grid User, confirm the node on which MGMTDB is running by executing.

On :

5. Enable and start ora.crf resource.

On each node, as root user:
