Now you can add the internal database MGMTDB after the GI installation.

Follow the note «MDBUtil: GI Management Repository configuration tool (Doc ID 2065175.1)»

In our case we check that the GIMR not exist:

[root@nodo01 tmp]# crsctl stat res -w "NAME = ora.mgmtdb"

Check where is the path for this installation on ASM:

[root@nodo01 sfw]# crsctl stat res -t -w "TYPE = ora.diskgroup.type"

Important!! You need the script in every node in your cluster in the same path.

Add the database:

[oracle@nodo01 sfw]$ ./mdbutil.pl --addmdb --target=+PROMGMTDB
mdbutil.pl version : 1.98
2019-07-19 11:25:38: I Starting To Configure MGMTDB at +PROMGMTDB...

root@nodo02's password:
2019-07-19 12:51:57: I MGMTDB & CHM configuration done!

Check status for GIMR:

[root@nodo01 tmp]# crsctl stat res -w "NAME = ora.mgmtdb"
NAME=ora.mgmtdb
TYPE=ora.mgmtdb.type
TARGET=ONLINE
STATE=ONLINE on nodo01
