Steps for deleting node in Oracle RAC (12c Release 1) environment :
Steps for Deleting an Instance From the Cluster database :-
Invoke dbca from node 1 (racpb1) :
[oracle@racpb1 ~]$ . .bash_profile [oracle@racpb1 ~]$ [oracle@racpb1 ~]$ dbca
Check number of Instance running status :
[oracle@racpb1 ~]$ srvctl status database -d orcl11g Instance orcl11g1 is running on node racpb1 Instance orcl11g2 is running on node racpb2
Check Instance removed from OCR :
[oracle@racpb1 ~]$ srvctl config database -d orcl11g Database unique name: orcl11g Database name: orcl11g Oracle home: /u01/app/oracle/product/12.1.0/db_1 Oracle user: oracle Spfile: +DATA/orcl11g/spfileorcl11g.ora Password file: Domain: localdomain.com Start options: open Stop options: immediate Database role: PRIMARY Management policy: AUTOMATIC Server pools: Disk Groups: DATA Mount point paths: Services: Type: RAC Start concurrency: Stop concurrency: OSDBA group: dba OSOPER group: oinstall Database instances: orcl11g1,orcl11g2 Configured nodes: racpb1,racpb2 Database is administrator managed
Remove Oracle RAC Database home :-
Disable and Stop listener :
[oracle@racpb3 ~]$ srvctl status listener -l LISTENER Listener LISTENER is enabled Listener LISTENER is running on node(s): racpb3,racpb2,racpb1 [oracle@racpb3 ~]$ srvctl disable listener -l LISTENER -n racpb3 [oracle@racpb3 ~]$ srvctl stop listener -l LISTENER -n racpb3
Update Inventory on deleting node (racpb3) :
[oracle@racpb3 ~]$ export ORACLE_SID=orcl11g3
[oracle@racpb3 ~]$ export ORACLE_HOME=/u01/app/oracle/product/12.1.0/db_1
[oracle@racpb3 ~]$ cd $ORACLE_HOME/oui/bin

Deinstall ORACLE_HOME :
Specify the “-local” flag as not to remove more than just the local node’s software.

Remove GRID_HOME :-
Check the pinned status of nodes :
[oracle@racpb1 ~]$ olsnodes -s -t racpb1 Active Unpinned racpb2 Active Unpinned racpb3 Active Unpinned
If the node is pinned, then run the crsctl unpin css to unpinned the nodes from GRID_HOME.
