PRCR 1086 resource ora.mgmtdb is already registered

In this article, I’m going to discuss the PRCR 1086 resource ora.mgmtdb resource which I was facing at the time of grid configuration on the Oracle Linux 6.7 platform. I have checked the logfile for grid configuration which is existing on the following path “/u01/app/oraInventory/logs/installActions2019-03-16_09-10-07PM.log“, and got the following information from the log.

PRCR 1086 resource ora.mgmtdb

After checking the logfile I’m doing google and found something interesting which I’m going to share with you.

During Grid configuration one database is created by default with the name of MGMTB so our configuration stuck here then we need to delete this DB configuration, once the configuration is deleted then click on try again.

Go on following path using cd command as a GRID user.

$cd /u01/app/12.1.0/grid/bin

Solution PRCR 1086

Then run the following command which is delete the configuration of MGMTB db.

$dbca -silent -deleteDatabase -sourceDB -MGMTDB

Output of above Query:

Look at the log file "/u01/app/grid/cfgtoollogs/dbca/_mgmtdb.log" for further details.

Now you can go head for your grid configuration, hopefully you will be successfully done your configuration.

I found this solution from “https://www.hhutzler.de/blog/recreate-the-gi-management-repository-database-12-1-0-1/#Delete_old_MGMTDB_database”.
