Using Oracle 11g R1 CRS clusterware with third party non-Oracle applications

Using Oracle 11g R1 CRS clusterware with third party non-Oracle applications (xclock)

We create a script x.sh in /usr/bin on each node of the cluster with content as specified below. The script is an action program – an executable to start/stop/check the application.

Content of x.sh

#!/bin/bash

# start/stop/check script for xclock example

# To test this change BIN_DIR to the directory where xclock is based

# and set the DISPLAY variable to a server within your network.

BIN_DIR=/usr/bin

LOG_DIR=/tmp

BIN_NAME=xclock

#DISPLAY=yourhost.domain.com:0.0

#export DISPLAY

if [ ! -d $BIN_DIR ]

then

echo “start failed”

exit 2

PID1=`ps -ef | grep $BIN_NAME | grep -v grep | grep -v xclock_app | awk ‘{ print $2 }’`

case $1 in

‘start’)

if [ “$PID1” != “” ]

then

status_p1=”running”

else

if [ -x $BIN_DIR/$BIN_NAME ]

then

umask 002

${BIN_DIR}/${BIN_NAME} & 2>${LOG_DIR}/${BIN_NAME}.log

status_p1=”started”

else

echo `basename $0`”: $BIN_NAME: Executable not found”

echo “$BIN_NAME: $status_p1”

;;

‘stop’)

if [ “${PID1}” != “” ]

then

kill -9 ${PID1} && echo “$BIN_NAME daemon killed”

else

echo “$BIN_NAME: no running Process!”

;;

‘check’)

if [ “$PID1” != “” ]

then

echo “running”

exit 0

else

echo “not running”

exit 1

;;

echo “Usage: “`basename $0`” {start|stop|check}”

;;

Esac

An application profile should be added to the OCR. The main attributes are

Action Program – an executable to start/stop/check the application

Privileges – which user can start/stop the application

Resource – a resource name for your application

Creating the profile

[root@raclinux1 bin]# ./crs_profile -create xclock_crs -t application -dir ./ -a /usr/bin/x.sh -r ora.raclinux1.vip

[root@raclinux1 bin]#ll

-rw-r–r– 1 root root 758 Dec 26 10:54 xclock_crs.cap

[root@raclinux1 bin]#

[root@raclinux1 bin]# chown oracle:oinstall xclock_crs.ca

[root@raclinux1 bin]#ll

-rw-r–r– 1 oracle oinstall 758 Dec 26 10:54 xclock_crs.cap

Registering the profile

[root@raclinux1 bin]# ./crs_register xclock_crs -dir ./

Checking the status of the resource

[root@raclinux1 bin]# ./crs_stat | grep -A5 xclock

NAME=xclock_crs

TYPE=application

TARGET=OFFLINE

STATE=OFFLINE

Setting the permissions and setting the owner

[root@raclinux1 bin]# ./crs_setperm xclock_crs -o root

[root@raclinux1 bin]# ./crs_setperm xclock_crs -u user:oracle:r-x

Checking the state

[root@raclinux1 bin]# ./crs_stat.sh

Oracle does not recommend using the same VIP for more applications. In our case we used the database VIP to operate with the Apache as well. To be in compliance with Oracle recommendations we ought to create a new VIP dedicated to the Apache server and use it instead of the database IP. It should operate exactly the same as the database VIP but will have a different IP.

8.4 Node raclinux1 comes back. VIP goes back to raclinux1. The xclock application is still present at node raclinux2.
