Oracle 10g RAC on ESXi3 using SLES9 SP5 – Part 9

February 16th, 2009

Verify the Oralce Clusterware Installation

With the introduction of Oracle RAC 10g, cluster management is controller by the evmd, ocssd and crsd processes.
Run the ps command on both nodes to make sure that the processes are running.

rac01:/u01/clusterware/cluvfy # ps -ef |grep d.bin
root 4694 1 0 Feb13 ? 00:00:00 /u01/crs1020/bin/crsd.bin reboot
oracle 5242 4692 0 Feb13 ? 00:00:00 /u01/crs1020/bin/evmd.bin
oracle 5344 5326 0 Feb13 ? 00:00:00 /u01/crs1020/bin/ocssd.bin
root 20078 10946 0 09:44 pts/1 00:00:00 grep d.bin

Next you should check the /etc/inittab file, which is processed whenever the runlevel changes:

rac01:/u01/clusterware/cluvfy # tail -f /etc/inittab
# mo:35:respawn:/usr/lib/fax/faxgetty /dev/modem

# vbox (voice box) getty
# I6:35:respawn:/usr/sbin/vboxgetty -d /dev/ttyI6
# I7:35:respawn:/usr/sbin/vboxgetty -d /dev/ttyI7

# end of /etc/inittab
h1:35:respawn:/etc/init.d/init.evmd run >/dev/null 2>&1 /dev/null 2>&1 /dev/null 2>&1 </dev/null

Another test that can be performed is by using the crsctl binary located in the /bin folder of the Clusterware installation:

rac01:/u01/clusterware/cluvfy # /u01/crs1020/bin/crsctl
Usage: crsctl check crs – checks the viability of the CRS stack
crsctl check cssd – checks the viability of CSS
crsctl check crsd – checks the viability of CRS
crsctl check evmd – checks the viability of EVM

rac01:/u01/clusterware/cluvfy # /u01/crs1020/bin/crsctl check crsd
CRS appears healthy

rac01:/u01/clusterware/cluvfy # /u01/crs1020/bin/crsctl check cssd
CSS appears healthy

rac01:/u01/clusterware/cluvfy # /u01/crs1020/bin/crsctl check evmd
EVM appears healthy

The crsctl stop command will stop the Oracle Clusterware deamons in the following order:
crsd, cssd and evmd last.

If there are any issues with the oracle Clusterware deamons the detailed log files are available under the $ORA_CRS_HOME/log/hostname folder.

Once you have determined that the installation is consistent on all nodes you can continue with the Oracle Database 10g Software installation.
