Last updated on OCTOBER 11, 2016

Applies to:

Oracle Database - Enterprise Edition - Version 10.2.0.1 and later
Information in this document applies to any platform.
This note apply to Unix platforms


Symptoms

When trying to start an instance using srvctl, the instance does not start.  The srvctl start command fails with CRS-0215.

$ srvctl start instance -d MYDB -i MYDB1
Attempting to start `ora.MYDB.MYDB1.inst` on member `myserver01`
`ora.MYDB.MYDB1.inst` on member `myserver01` has experienced an unrecoverable failure.
Human intervention required to resume its availability.
CRS-0215: Could not start resource 'ora.MYDB.MYDB1.inst'. 


Diagnostic analysis:

* The instance can be started with no errors by sql*plus.
* Tracing the srvctl command shows that the crs_start command fails with status 115.
* No information is recorded in the imon logs.

* crsd.log show the instance can't be stopped either after the instance start failure and set the instance state in UNKNOWN

Changes

Permissions and/or ownership to the imon logs under $ORACLE_HOME/log/<host>/racg have changed (although the DBA may not be aware of this change).
