Cluster query scripts

The scripting library provides multiple script procedures to automate the application server configurations. Use the scripts in this topic to determine if clusters and cluster members exist and to display the clusters and cluster members configured in our environment. We can run each script individually, or combine procedures to create custom automation scripts.

The AdminClusterManagement script procedures are located in the app_server_root/scriptLibraries/server/V70 directory.

Use the following script procedures to query the cluster configuration:

• checkIfClusterExists

• checkIfClusterMemberExists

• help

• listClusters

• listClusterMembers

checkIfClusterExists
