I have done many duplication before in sinlge instance databases using a backup tool and rman catalog. At the moment i was trying to do a RAC database duplication and facing some issues. For this i was doing a testing on my 1-node RAC. Primary and duplicated database is on the same Host and oracle version is 10.2.0.3. I perfomed following steps:

1.Created a DUPL database using DBCA.
2.Created a pfile using spfile.
3.Dropped all the datafiles, controlfiles and redo log files.
4.Started the database in nomount using pfile.
5.Disable cluster related parameters in pfile.
6.Took a full backup of the MAIN database with archivelog on disk.
6.Duplicate the database and it is done successfully.
7.Shutdown the instance and enabled cluster parameters.
8.Start instance using SRVCTL fails with error CRS-0215: Could not start resource 'ora.DUPL.DUPL1.inst'

But if start the instance using sqlplus it comes up nicely. There is not much information in alert log files. Can you please highlight what i am missing here?

NAME=ora.DUPL.DUPL1.inst
TYPE=application
TARGET=ONLINE
STATE=ONLINE on cpbttodevorra001

NAME=ora.DUPL.db
TYPE=application
TARGET=ONLINE
STATE=ONLINE on cpbttodevorra001


It shows online here. And when i start the resource by srvctl start resources ora.DUPL.DUPL1.inst , it starts fine. But when i start the database (srvctl start database -d DUPL) it fails.

Seems your spfile has issues.
After duplication,
check for valid spfile with valid cluster settings.

Hi,

Below are the entries of the alert log file of the database.

In Some google thread, the error pointer is the instance_number parameter in the parameter file, though i have specified this parameter in the init file.

Thanks

Hi All,

This problem is resolved now. It was instance name case sensitiveness of the instance name in the OCR/spfile.

https://support.oracle.com/CSP/ui/flash.html#tab=KBHome (page=KBHome&id=()),(page=KBNavigator&id=(bmDocID=749515.1&bmDocTitle='ORA-29760:%20instance_number%20parameter%20not%20s pecified'%20When%20Starting%20the%20Database%20with%20Srvctl&from=BOOKMARK&bmDocType=PROBLEM&viewingMode=1143&bmDocDs rc=KB))

Interesting issue though:-)

Thanks for all your inputs through out the course of this issue. Much appreciated.

cheers
Nukesh
