Yes, but that was not how the document was written. The major difference is that you have to manually test everything rather than using the cluster tools to help you. e.g. to stop (being consistent with the presented example in the howto, and assuming all environment vars are set correctly): /usr/share/cluster/oracledb.sh stop umount /mnt/oracle ip addr del 192.168.1.20/22 dev eth0 or to start the service: ip addr add 192.168.1.20/22 dev eth0 mount -t ext3 /dev/sdb7 /mnt/oracle /usr/share/cluster/oracledb.sh start If the cluster is set up correctly, this will work on both nodes (note that you must stop it on one before starting on another). > 2> The /mnt/oracle mount point is temporary for the > oracle installation or should i write on /etc/fstab ? It is mounted by the cluster when you start the service. Do not place it in /etc/fstab, as mounting an ext3 file system on multiple nodes will cause you to have a corrupt file system *very* quickly! > 3> Can i mention ORACLE_HOME,ORACLE_BASE,ORACLE_SID > etc on .bash_profile of every node or leave it as it > is only create oracle user and group? You can, and it will help the testing/debugging phase. However, it is not used by the cluster software when starting/stopping Oracle; everything must be in the cluster configuration. Don't forget to set ORACLE_HOSTNAME (which is used by the script to trick Oracle in to using the service IP address/hostname that you set in Part 2 - step 2), since apparently OUI_HOSTNAME does not seem to work the way I expected it should. > 4> Where should i place oracledb.sh file?

Part 1, step 6 (steps to take on all nodes): Install the oracledb.sh resource agent in to /usr/share/cluster > 5>What is the exact use of oracledb.sh file? It is called by the cluster software to start/stop/check status of the Oracle instance. Additionally, if you have the environment variables set up correctly, it will start/stop Oracle outside of the cluster environment, too (just like a normal initscript...). > 6> How can i shutdown the oracle, should i write > script for that, like orastop and orastart for up the > oracle? If your environment variables are set correctly and the cluster is not running: /usr/share/cluster/oracledb.sh stop Once the instance is managed by RHCS (and RHCS is running!), you can use 'clusvcadm' to disable and enable the now failover-capable Oracle instance, and move it around (see the clusvcadm man page for more details). -- Lon -- Linux-cluster@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/linux-cluster
