Q: We have a 4-node RAC. I need to disable autostart of the DB on one node only.
How to do it and how to see autostart parameters, confirming that specified instance was disabled?
I didn’t find this in the output of the command: crsctl status res –t.
A:
You're right, crsctl status res –t don't show the instance autostart parameter.
The crsctl also don't show the disabled instance:
[root@exa1dbadm01 ~]# crsctl status res ora.orcl.db

TYPE=ora.database.type

Q: Which command can be used to disable automatic start?
A:
To disable/enable autostart for whole DATABASE (all instances):
srvctl disable database -db $DBNAME
srvctl enable database -db $DBNAME
Ins a such a way we disable autostart of the database on all nodes. All instances.
But how can we prevent autostart on one node only? Only for one instance ?
To disable/enable autostart for certain instance:
srvctl disable instance -db orcl –i orcl2
srvctl enable instance -db orcl –i orcl2
Q: How to see autostart property for disabled instance in the cluster settings?
A:
Let experiment.
1st try as "grid" account.
Choose the appropriate DB.
I like use -v option is srvctl because it bring more information:
[grid@exa1dbadm01 ~]$ srvctl config db -v
orcl /u01/app/oracle/product/19.0.0.0/dbhome_1 19.0.0.0.0
ok_awr /u01/app/oracle/product/19.0.0.0/dbhome_1913 19.0.0.0.0
[grid@exa1dbadm01 ~]$ srvctl disable instance -d orcl -i orcl2
PRCR-1012 : Failed to disable resource ora.orcl.db
PRCR-1071 : Failed to register or update resource ora.orcl.db
CRS-0245: User doesn't have enough privilege to perform the operation
The syntax is right, but "grid" account in OS doesn't have enough privileges. OK.
The rule to use srvctl: USE SRVCTL FROM ORACLE HOME WHERE DB IS STARTED. DON'T USE SRVCTL FROM GRID HOME OR OTHER ORACLE HOME.
[root@exa1dbadm01 ~]# su - oracle
[oracle@exa1dbadm01 ~]$ srvctl config db -v
orcl /u01/app/oracle/product/19.0.0.0/dbhome_1 19.0.0.0.0
ok_awr /u01/app/oracle/product/19.0.0.0/dbhome_1913 19.0.0.0.0
[oracle@exa1dbadm01 ~]$ /u01/app/oracle/product/19.0.0.0/dbhome_1/bin/srvctl disable instance -d orcl -i orcl2
Previous command was completed successfully. And silently.
Let obtain the status (with -v, verbose):
[oracle@exa1dbadm01 ~]$ /u01/app/oracle/product/19.0.0.0/dbhome_1/bin/srvctl status instance -d orcl -i orcl1,orcl2 -v
Instance orcl1 is running on node exa1dbadm01 with online services srvorcl1. Instance status: Open.
Instance orcl2 is running on node exa1dbadm02. Instance status: Open.
The above output don't show the DISABLED.
May be my instance is not disabled? Let me disable it 2nd time:
[oracle@exa1dbadm01 ~]$ /u01/app/oracle/product/19.0.0.0/dbhome_1/bin/srvctl disable instance -d orcl -i orcl2
PRCC-1013 : orcl was already disabled on exa1dbadm02
PRCR-1003 : Resource ora.orcl.db is already disabled
But "srvctl status instance" don't show that instance autostart property is disabled|enabled.
srvctl CONFIG - don't show the DISABLED instance too:
[oracle@exa1dbadm01 ~]$ srvctl config db -d orcl

How to view autostart at instance level?
As you see the "-v" option don't show the DISABLED instance:
[oracle@exa1dbadm01 ~]$ /u01/app/oracle/product/19.0.0.0/dbhome_1/bin/srvctl status instance -d orcl -i orcl1,orcl2 -v
Instance orcl1 is running on node exa1dbadm01 with online services srvorcl1. Instance status: Open.
Instance orcl2 is running on node exa1dbadm02. Instance status: Open.
The only "-f" option gives the expected output:
[oracle@exa1dbadm01 ~]$ /u01/app/oracle/product/19.0.0.0/dbhome_1/bin/srvctl status instance -d orcl -i orcl1,orcl2 -f -v
Instance orcl1 is running on node exa1dbadm01 with online services srvorcl1. Instance status: Open.
Instance orcl2 is disabled on node exa1dbadm02
Instance orcl2 is running on node exa1dbadm02. Instance status: Open.
Bingo!
Don't forget to restore the instance autostart:
[oracle@exa1dbadm01 ~]$ /u01/app/oracle/product/19.0.0.0/dbhome_1/bin/srvctl enable instance -d orcl -i orcl2
