Hi All

when I use srvct status to check the status of the instances it shows the instnce is down while the instance is actually up.

[qaoraerp@qa1-rora ~]$ srvctl status database -d QAERPRPT
Instance QAERPRPT1 is not running on node qa1-rora
Instance QAERPRPT2 is running on node qa2-rora
[qaoraerp@qa1-rora ~]$


ps -ef|grep pmon shows the instance up

[qaoraerp@qa1-rora ~]$ ps -ef|grep pmon
qaoraerp  1314 27205  0 01:51 pts/3    00:00:00 grep pmon
qaoraerp 10798     1  0 Jun27 ?        00:06:27 ora_pmon_D1ERP1
qaoraerp 10800     1  0 Jun27 ?        00:07:42 ora_pmon_D1ERPRPT1
qaoraerp 10802     1  0 Jun27 ?        00:08:00 ora_pmon_QAERP1
d1oraerp 10958     1  0 Jun27 ?        00:01:03 ora_pmon_D1P2P1
qaoraerp 10987     1  0 Jun27 ?        00:00:17 asm_pmon_+ASM1
qaoraerp 20682     1  0 Jun28 ?        00:04:25 ora_pmon_QAERPRPT1
qaoraerp 21260     1  0 Jun28 ?        00:00:35 ora_pmon_QAP2P1


even I can log in to the instance and status is open.

SQL> select instance_name,status from v$instance;

INSTANCE_NAME    STATUS
---------------- ------------
QAERPRPT1        OPEN


So it is clear that the instance is up. Can anyone tell what might be the reason for srvctl not to detect it?

Thanks
Ridhi Sundar

The clusterware does sometimes get it wrong. For example, when you first register your instance in the OCR with
srvctl add instance -d dbname -i instancename
it will show as "not running", I guess because at the time it was started the clusterware didn't know it existed. Just issue
srvctl start instance -d QAERPRPT -i QAERPRPT1
nothing will be started (because it already is) but iut will be reported correctly from then.

Hi John

Thanks for the responce. But it did not work.

[qaoraerp@qa1-rora ~]$ srvctl start instance -d QAERPRPT -i QAERPRPT1
PRKP-1001 : Error starting instance QAERPRPT1 on node qa1-rora
CRS-0233: Resource or relatives are currently involved with another operation.
[qaoraerp@qa1-rora ~]$ srvctl status database -d QAERPRPT
Instance QAERPRPT1 is not running on node qa1-rora

Hello again - this looks as though you have a real problem, not just confused clusterware. I certainly can't give a simple answer.
If it were one of my databases, I would start by looking at all the log files. And probably try to shutdown the all the resources, using sqlplus, srvctl, crs_stop, and so on. Since you have several instances on the node, I guess you can't re-start the clusterware?
Sometimes, I have had databases in a similar state: everything is working perfectly for the users, but from our side it is un-manageable. So just leave it running, and re-start the entire environment at your next maintenance window. Good luck - and perhaps your users won't notice any problems.

There is no problem on users side. Instance is up and running fine. But bot sure why srvctl shows db down. Need to restart the services in next downtime window. Still if any one is having any idea about such issue please share your experience.

remove the instances from the CRS registry and then re-register them. Make sure you are correctly stating the oracle_home when you register them.

Before doing anything radical, just reboot the servers next downtime and see if that fixes it.
