Cluster actions

Olga Semme

This article describes the main actions available in the ADCM interface for working with an ADS cluster.

Actions with the cluster are performed on the Clusters page.

Refer to ADCM documentation for an overview of the Clusters page and common actions.

 
The set of available actions depends on the cluster state:

  • For new cluster (cluster state created) the following action is available:

    • Install — installs all cluster services.

    • Validate configuration — checks for duplicate ports on each host before installing the services.

  • After cluster installation (cluster state installed) the following actions are available:

    • Restart — stops and then starts all services of the cluster. To restart the cluster, select the required value for the Apply configs from ADCM option. If the value true is selected, then the service is launched taking into account all the parameters specified in the settings of this service in ADCM. Otherwise, the service settings in ADCM are ignored. Next, confirm the action by clicking Run.

    • Start — starts the cluster services. To start the cluster, select the required value for the Apply configs from ADCM option and confirm the action by clicking Run.

      The services are launched in the same sequence as during installation — first the required services, then the additional ones.

    • Stop — stops cluster services. When the cluster is stopped, additional services are stopped first, then the required ones.

    • Manage Kerberos — allows you to enable, reconfigure, and disable Kerberos authentication.

      Once you select an action, the window that appears will offer several options for running the action:

      Every option of the Manage Kerberos action can be combined with the Custom kerberization settings option.

      After enabling authentication for one of the protocols, when you select the Manage Kerberos action, in the window that opens you will be asked to edit the already enabled option and the Custom kerberization settings option.

    • Manage SSL — allows you to enable, reconfigure, and disable channel security over the SSL protocol. Configuring channel security using the SSL protocol is carried out in accordance with the article SSL channel security.

    • Reinstall status-checker — initiates reconfiguration and restart of statuschecker for all cluster services. Used when migrating a cluster under the control of a new ADCM server.

    • Validate configuration — checks for duplicate ports on each host.

  • For a cluster prepared for upgrade (the cluster state is upgrade from X.X.X), an available action is:

IMPORTANT

  • Prior to upgrading, verify that the configurations on the hosts align with the ADCM configurations. If there were manual edits on the hosts, bring them into a consistent state yourself.

  • When upgrading an ADS cluster, the product upgrade order should be as follows:

  1. ADCM

  2. ADPS

  3. ADS

To update the cluster version:

  1. Download the bundle ADS new version — see step Upload a cluster bundle to ADCM in the Create a cluster article.

  2. Open the Clusters page. After downloading the bundle, the icon upgrade default becomes active.

  3. Click on the icon upgrade default. In the Upgrade Cluster window that opens, select the version available for upgrade and click Upgrade.

    Start upgrade

  4. In the dialog box that opens, click Run.
