In this article , we will explain the steps required for deinstalling 2 node grid infrastructure.

STEPS OVERVIEW:

  • Deinstall oracle database homes if any
  • Deinstall grid infrastructure
  • Manually delete grid_home and oracle_home if anything is reported at 2nd stage.

NOTE – > This deinstall process, will drop the database. So if your data is critical make sure you to take a full backup of the database before proceeding with the deinstallation.

However if your database size is too big and you are unable to take backup, Then there is an method , where you can deinstall and reinstall the grid infrastructure without losing your data.

DEMO:

NODE LIST – DBHOST1, DBHOST2G

GRID VERSION  – 19C

 

1.Deinstall oracle database homes

Check if any database is running in the server. If database is running or oracle binary is there, then we need to clean them before deinstalling grid.


[oracle@DBHOST1 deinstall]$ crsctl status resource -w "TYPE = ora.database.type" -t

                                                             3.0/dbhome_1,STABLE
      2        ONLINE  ONLINE       DBHOST2               Open,HOME=/oracle/ap
                                                             p/oracle/product/19.
                                                             3.0/dbhome_1,STABLE
--------------------------------------------------------------------------------

Run deinstall utility from ORACLE_HOME. This will deinstall the oracle database home from both the nodes.


[oracle@DBHOST1 deinstall]$ cd $ORACLE_HOME/deinstall
