A Cluster with Solaris and Oracle RAC – Avoid panic when rebooting

You just rebooted a server that you know that runs Oracle RAC and the other node rebooted. This happened because CRS was active and you first need to disable to reboot the other node. You’ll see this message on /var/adm/messages

Jun 5 14:15:19 solaris_rac2 root: Oracle clsomon failed with fatal status 12.
Jun 5 14:15:20 solaris_rac2 root: Oracle CRS failure. Rebooting for cluster integrity.
rebooting…

Run this command to stop CRS. Your path may vary according to where you installed the binary.

root@solaris_rac1:~ # /u01/app/oracle/product/11.1.0/bin/crsctl stop crs
Stopping resources.
This could take several minutes.
Successfully stopped Oracle Clusterware resources
Stopping Cluster Synchronization Services.
Shutting down the Cluster Synchronization Services daemon.
Shutdown request successfully issued.

Check the status with crsctl check crs. It should display the message below

root@solaris_rac1:~ # /u01/app/oracle/product/11.1.0/bin/crsctl check crs
Failure 1 contacting Cluster Synchronization Services daemon
Cannot communicate with Cluster Ready Services
Cannot communicate with Event Manager

After you reestablish the machine, CRS should start automatically

root@solaris_rac1:~ # /u01/app/oracle/product/11.1.0/bin/crsctl check crs
Cluster Synchronization Services appears healthy
Cluster Ready Services appears healthy
Event Manager appears healthy

Starting an Oracle database instance

Here is a reference if I need to start an Oracle database instance. It may not be the best way but this is how I done.

I became the user oracle

root@solaris:/ # su – oracle

Exported the variable that sets the instance that I’ll deal with

oracle@solaris:~ $ export ORACLE_SID=testing

Started sqlplus

oracle@solaris:~ $ sqlplus /nolog

SQL> connect /as sysdba

And finally started the instance

Problems mounting an OCFS2 filesystem under Linux – Transport endpoint is not connected

I had a problem mounting an ocfs2 filesystem under Oracle Cluster Management Software.

root@oracm1:~# mount -a
mount.ocfs2: Transport endpoint is not connected while mounting /dev/mapper/oravg01-lvu03 on /u03. Check ‘dmesg’ for more information on this error.

The error message said to check dmesg for more information and there it was. The cluster was not handshaking with the other node because the network timeout was different.

root@oracm1:~# dmesg
Buffer I/O error on device sdab, logical block 262143
(8290,0):o2net_check_handshake:1180 node oracm2 (num 1) at 192.168.2.101:7777 uses a network idle timeout of 10000 ms, but we use 30000 ms locally.  disconnecting

(8211,0):ocfs2_mount_volume:1133 ERROR: status = -107
ocfs2: Unmounting device (253,7) on (node 0)

I entered the other cluster node to check the cluster status. The heartbeat is active and the timeout is 10000.

root@oracm2:~# service o2cb status

Checking O2CB heartbeat: Not active

The host oracm1 needs to have exactly the same configuration as oracm2, so I invoked the o2cb script with the configure parameter to reconfigure the timeout.

root@oracm1:~# service o2cb configure
Configuring the O2CB driver.

This will configure the on-boot properties of the O2CB driver.
The following questions will determine whether the driver is loaded on
boot.  The current values will be shown in brackets (‘[]’).  Hitting
<ENTER> without typing an answer will keep that current value.  Ctrl-C
will abort.

Load O2CB driver on boot (y/n) [y]: y
Cluster to start on boot (Enter “none” to clear) [ocfs2]: ocfs2
Specify heartbeat dead threshold (>=7) [61]: 61
Specify network idle timeout in ms (>=5000) [30000]: 10000
Specify network keepalive delay in ms (>=1000) [5000]: 5000
Specify network reconnect delay in ms (>=2000) [2000]: 2000
Writing O2CB configuration: OK
O2CB cluster ocfs2 already online

I restarted the o2cb service

root@oracm1:~# service o2cb stop
root@oracm1:~# service o2cb start

And checked that the node entered the cluster.

root@oracm1:$ORACLE_HOME/oracm/log # grep “Successful reconfiguration” cm.log
Successful reconfiguration,  2 active node(s) node 1 is the master, my node num is 0 (reconfig 22) {Thu Jun 11 13:17:32 2009 }
