Troubleshooting 15
The following are the list of issues that can result in CRS failure:
• OCR file and Voting disk are inaccessible.
Correct the I/O problem and attempt to start the service again
by rebooting the node or by running
root.sh from
/crs/oracle/product/11.1.0/crs/
• OCR file and Voting disk have not been cleared and contain old
information.
Clear the OCR and Voting disks to erase the old information.
You can do this on RHEL4 by entering the following lines:
dd if=/dev/zero of=/dev/raw/ocr.dbf
dd if=/dev/zero of=/dev/raw/votingdisk
Attempt to start the service again by rebooting the node or by running
r
oot.sh from /crs/oracle/product/11.1.0/crs/
• The Oracle User does not have permissions on /var/tmp
(specifically
/var/tmp/.oracle ).
Make User Oracle the owner of
/var/tmp/.oracle by entering the following
command:
chown oracle.oinstall /var/tmp/.oracle
Attempt to start the service again by rebooting the node or by running
root.sh from : /crs/oracle/product/11.1.0/crs/
If all the other CRS troubleshooting steps fail, then perform the following:
Enable debugging by adding the following line:
to root.sh:
set -x
Attempt to start the service again by running root.sh from:
/crs/oracle/product/11.1.0/crs/
Check log files in the following directories to diagnose the issue:
$ORA_CRS_HOME/crs/log
$ORA_CRS_HOME/crs/init
