Alternate Sun Cluster HA for BEA WebLogic Server Configurations

The installation, registration, and configuration procedures in this chapter assume that you are installing a Simple Configuration as described in Simple Configuration. This section provides examples of other possible Sun Cluster HA for BEA WebLogic Server configurations.

Creating a Simple BEA WebLogic Server Resource

This configuration assumes that the START script, startWebLogic.sh, can start the BEA WebLogic Server without any arguments to the script. The username and password needed to start the BEA WebLogic Server can be configured within this START script or in the boot.properties file.


# scrgadm -a -j bea-rs -t SUNW.wls- -g bea-rg\
-x Confdir_list=/global/bea/beahome/weblogic700\
-x Server_url=http://logical_host1:7001\
-x Start_script=/global/bea/beahome/user_projects/petstore/startWebLogic.sh

Creating a Resource with a Server Name Argument

If the BEA WebLogic Server START script startManagedWebLogic.sh uses a Managed Server name as an argument, then the extension property Server_name can be set. The START script startManagedWebLogic.sh can be used to start several Managed Servers. The ADMIN_URL must be configured within the START script. To start the BEA WebLogic Server manually, use the following commands.


cluster-node-1> cd /global/wls/user_projects/petstore
cluster-node-1> ./startManagedWebLogic.sh petstore1

To configure a Sun Cluster HA for BEA WebLogic Server resource whose start script takes the server name petstore1, use the following commands.


# scrgadm -a -j bea-rs -t SUNW.wls -g bea-rg\
-x Confdir_list=/global/bea/beahome/weblogic700\
-x Server_url=http://logical_host1:7001\
-x Start_script=/global/bea/beahome/user_projects/petstore/startWebLogic.sh\
-x Server_name=petstore1

To configure another Sun Cluster HA for BEA WebLogic Server resource which uses the same START script for a different server, petstore2, use the following commands.


# scrgadm -a -j bea-rs -t SUNW.wls -g bea-rg\
-x Confdir_list=/global/bea/beahome/weblogic700\
-x Server_url=http://logical_host1:7001\
-x Start_script=/global/bea/beahome/user_projects/petstore/startWebLogic.sh\
-x Server_name=petstore2

Creating a Resource Which Will Shut Down Smoothly

The default for the Sun Cluster HA for BEA WebLogic Server STOP method kills the BEA WebLogic Server process to shut down the instance. If this is not desirable, set the Smooth_shutdown extension property to TRUE to enable smooth shutdown of the BEA WebLogic Server. If this extension property is enabled, WLS_USER and WLS_PW must be set in the START script. If this is a security concern, you must let Sun Cluster HA for BEA WebLogic Server perform the default forced shutdown (kill the process).

To configure a resource which will shut down smoothly, use the following commands.


# scrgadm -a -j bea-rs -t SUNW.wls -g bea-rg\
-x Confdir_list=/global/bea/beahome/weblogic700\
-x Server_url=http://logical_host1:7001\
-x Start_script=/global/bea/beahome/user_projects/petstore/startWebLogic.sh\
-x Server_name=petstore1\
-x Smooth_shutdown=TRUE

Creating a Resource Which Will Probe the Database

Sun Cluster HA for BEA WebLogic Server does not probe the database health. If the database is down when Sun Cluster HA for BEA WebLogic Server starts up, the data service will fail to start. If you want Sun Cluster HA for BEA WebLogic Server to probe the database, then your own database probe script can be supplied to Sun Cluster HA for BEA WebLogic Server as an extension property. This database probe must return zero for success and non-zero for failure.

To configure a resource with the DB_probe script extension property set, use the following commands.


# scrgadm -a -j bea-rs -t SUNW.wls -g bea-rg\
-x Confdir_list=/global/bea/beahome/weblogic700\
-x Server_url=http://logical_host1:7001\
-x Start_script=/global/bea/beahome/user_projects/petstore/startWebLogic.sh\
-x Server_name=petstore1\
-x Smooth_shtudown=TRUE\
-x DB_probe_script=/global/bea/script/db_probe_script

Creating a Resource That Monitor URIs

To enable the Sun Cluster HA for BEA WebLogic Server resource to monitor URIs that are served by the BEA WebLogic Server configured in the resource, use the following commands to set the extension property Monitor_uri_list.


# scrgadm -a -j bea-rs -t SUNW.wls -g bea-rg\
-x Confdir_list=/global/bea/beahome/weblogic700\
-x Server_url=http://logical_host1:7001\
-x Start_script=/global/bea/beahome/user_projects/petstore/startWebLogic.sh\
-x Server_name=petstore1\
Smooth_shutdown=TRUE\
DB_probe_script=/global/bea/script/db_probe_script\
-x Monitor_uri_list=http://logical_host1:7001/petstore,http://logical_host1:7001/bookstore
