三.Install Oracle databse:
1.Run rootpre.sh scripts:
Before install,you must run rootpre.sh from oralce meadia:
[root@dbserv1 database]#./rootpre.sh ./rootpre.sh output will be logged in /tmp/rootpre.out_12-05-28.13:38:43 Checking if group services should be configured.... Group "hagsuser" does not exist. Creating required group for group services: hagsuser Please add your Oracle userid to the group: hagsuser Configuring HACMP group services socket for possible use by Oracle. The group or permissions of the group services socket have changed. Please stop and restart HACMP before trying to use Oracle. [root@dbserv2 database]#./rootpre.sh ./rootpre.sh output will be logged in /tmp/rootpre.out_12-05-28.13:38:11 Checking if group services should be configured.... Group "hagsuser" does not exist. Creating required group for group services: hagsuser Please add your Oracle userid to the group: hagsuser Configuring HACMP group services socket for possible use by Oracle. The group or permissions of the group services socket have changed. Please stop and restart HACMP before trying to use Oracle.
After do above step then you can install oracle database and copy the oracle installed files to another node.Make sure that the oracle listener address is you service ip.
2.Create start and stop scripts:
[root@dbserv1 /]#vi /etc/dbstart #!/usr/bin/bash #Define Oracle Home ORACLE_HOME=/u01/app/oracle/product/11.2.0/dbhome_1 #Start Oracle Listener if [ -x $ORACLE_HOME/bin/lsnrctl ]; then su - oracle "-c lsnrctl start" fi #Start Oracle Instance if [ -x $ORACLE_HOME/bin/sqlplus ]; then su - oracle "-c sqlplus"<<EOF connect / as sysdba startup quit EOF fi [root@dbserv1 /]#vi /etc/dbstop #!/usr/bin/bash #Define Oracle Home ORACLE_HOME=/u01/app/oracle/product/11.2.0/dbhome_1 #Stop Oracle Listener if [ -x $ORACLE_HOME/bin/lsnrctl ]; then su - oracle "-c lsnrctl stop" fi #Stop Oracle Instance if [ -x $ORACLE_HOME/bin/sqlplus ]; then su - oracle "-c sqlplus"<<EOF connect / as sysdba shutdown immediate quit EOF fi [root@dbserv1 /]#chmod +x /etc/dbst* [root@dbserv1 /]#scp /etc/dbst* dbserv2:/etc
四.Register A Application to Resource Group
