This article describes the basic actions available for working with an ADS cluster in the ADCM interface.
Actions with a cluster are performed on the CLUSTERS tab.
For each cluster, ADCM provides:
Name, Bundle, Description, State — columns displaying information about the cluster;
Status, Actions, Import, Upgrade, Config — columns with interactive interface elements (icons).
For some columns, it is possible to sort rows (created clusters) alphabetically.
The columns display the following information about the cluster:
Name — name given when the cluster was created.
Bundle — name and version of the bundle.
Description — description entered when the cluster was created.
State — current state of the cluster (created, installed, kerberized, etc.).
Working with interactive UI elements in the cluster is done by clicking on the element (icon).
On the JOBS tab, you can view the process of some actions (for example, starting or stopping a cluster, updating a cluster). Also on the JOBS tab, you can analyze errors if they occur.
When you click on the Status icon, you go to the Status cluster menu page, which shows the statuses of all components of all services on hosts.
When you click on the Actions icon, the drop-down list offers actions for working with the cluster.
Start and Stop respectively start and stop all cluster services. The services are launched in the same sequence as during installation — first the required services, then the additional ones. When the cluster is stopped, additional services are stopped first, then the required ones.
After selecting the action Start or Stop, click Run in the opened dialog box.Start cluster
Enable Kerberos provides a choice of Kerberos authentication using the previously configured KDC server (Existing MIT KDC) or LDAP server (Existing Active Directory). Authentication is configured in accordance with the articles Kerberos SASL and LDAP.Enable Kerberos authentication protocol

Enable SSL starts enabling of channel security via the SSL protocol. Configuring the channel protection via the SSL protocol is carried out in accordance with the article SSL channel security.Enable SSL channel security
Reinstall status-checker is used when migrating an ADS cluster to a new ADCM server. Running Reinstall status-checker starts a reconfiguration and restart of the statuschecker for all cluster services.
When you click on the Import icon, you go to the Import cluster menu page, on which you install the import of components for integrating the ADS cluster with other clusters installed in ADCM (Enterprise Tools, Monitoring, ADPS).
The Upgrade icon is used to upgrade the cluster version.
