How to open an RAC database correctly(version 12.1) from "mounted" state?
Earlier, nodes #01 and #02 were opened manually by the command
alter database open.
Now, the database in this state:
SQL> select instance_name,status from gv$instance; INSTANCE_NAME STATUS node01 OPEN node02 OPEN node04 MOUNTED node03 MOUNTED ~$ srvctl status database -d cldb -v Instance node01 is running on node srv-n01. Instance status: Open,Readonly. Instance node02 is running on node srv-n02. Instance status: Open,Readonly. Instance node03 is running on node srv-n03. Instance status: Mounted (Closed). Instance node04 is running on node srv-n04. Instance status: Mounted (Closed).
