To configure or unconfigure application monitoring

Use the Veritas High Availability view to configure or un-configure an application for monitoring in a cluster under Cluster Server (VCS) control.

The view provides you with specific links to perform the following configuration tasks:

  • Configure a VCS cluster:

    If the local system is not part of a VCS cluster, the Veritas High Availability view appears blank, except for the link Configure a VCS cluster.

    Before you can configure application monitoring, you must click the Configure a VCS cluster link to launch the VCS Cluster Configuration wizard. The wizard helps you configure a VCS cluster, where the local system is by default a cluster system.

  • Configure the first application for monitoring in a VCS cluster:

    If you have not configured any application for monitoring in the cluster, the Veritas High Availability view appears blank except for the link Configure an application for high availability.

    Click the link to launch the Veritas High Availability Configuration Wizard. Use the wizard to configure application monitoring.

    Also, in applications where the Veritas High Availability Configuration Wizard is supported, for detailed wizard-based steps, see the application-specific VCS agent configuration guide. For custom applications, see the Cluster Server Generic Application Agent Configuration Guide.

  • Add a system to the VCS cluster:

    Click Actions > Add a System to VCS Cluster to add a system to a VCS cluster where the local system is a cluster member. Adding a system to the cluster does not automatically add the system as a failover system for any configured application. To add a system as a failover system, see (add a cross-reference to 'To add or remove a failover system'.

  • Configure an application or add an application to the existing application monitoring configuration:

    Click Actions > Configure an application for high availability to launch the Veritas High Availability Application Monitoring Configuration Wizard. Use the wizard to configure application monitoring.

  • Unconfigure monitoring of an application:

    In the appropriate row of the application table, click More > Unconfigure Application Monitoring to delete the application monitoring configuration from the VCS.

    Note that this step does not remove VCS from the system or the cluster, this step only removes the monitoring configuration for that application.

    Also, to unconfigure monitoring for an application, you can perform one of the following procedures: unconfigure monitoring of all applications, or unconfigure VCS cluster.

  • Unconfigure monitoring of all applications:

    Click Actions > Unconfigure all applications. This step deletes the monitoring configuration for all applications configured in the cluster.

  • Unconfigure VCS cluster:

    Click Actions > Unconfigure VCS cluster. This step stops the VCS cluster, removes VCS cluster configuration, and unconfigures application monitoring.
