Configure Servers for Advanced Availability

Last update August 21, 2015

The advanced availability configuration offers more resilience to server outages, higher application availability, and supports rolling maintenance with minimal end-user disruption. This configuration requires one background server, one or more standby servers, and one or more application servers, all of which you need to configure.

Follow these steps:

  1. Configure the Background Server. 
  2. Add a Server.
  3. Configure the Standby or Application Servers.
  4. Verify the Server Details.

Configure the Background Server

Configure the background server before configuring the application or standby servers.

Follow these steps:

  1. Log in to the server that you want to configure as the background server.
  2. Use the pdm_configure command to start the configuration.
    The Select Server Configuration screen opens.
  3. Select Advanced Availability as the configuration type and follow the prompts to complete the configuration. For more information, see Server Configuration Utility.
    The background server is configured.

Add a Server


 If you want to install a new server in your CA SDM deployment, you must first add the corresponding server record before you configure it.

Follow these steps:

  1. Log in to the following server, depending on your CA SDM configuration:
    • Conventional: Primary server
    • Advanced availability: Background server
  2. Select System, Servers from the Administration tab.
  3. Click Create New to add a server record for the following server, depending on CA SDM configuration:
    • Conventional: Secondary server
    • Advanced availability: Application or standby server
  4. Complete the fields as appropriate for the server.
  5. Click Save to add the server detail.

Create Server Fields

The following fields appear when you create or update a server:

  • Host Name
    Specifies the local host name of the server. The local host name is stored in the usp_servers table in local_host column.

    Important! Ensure that host name is entered as case-sensitive in the usp_servers table.
  • Attachment Servlet Path
    You must specify the fully qualified domain name of a server using this field:
    http://<host>:<port>/CAisd/Upload/Servlet
    Where <host> is the fully qualified domain name of a server.
    We recommend that you configure this field.
  • Time Zone
    Specifies the time zone where the server is located. This time zone value is used to trigger events in the application. This value is used only if the Use End User Time Zone option is not selected, or if no time zone is specified for the service type.
  • Record Status
    Indicates the state of the server. Active status indicates that the server is a part of the CA SDM deployment.

    Important! If you have inactivated any server, it is recommended not to start CA SDM services on that server. This action may result in unexpected behaviour.
  • Server Type
    Specifies the type of server that you want to configure. Following server types can be selected, depending on your CA SDM configuration:
    • Advanced Availability: Application or standby server
    • Conventional: Secondary server
  • Configured
    Available only for advanced availability configuration. This field indicates the state of the configured server. The default value of this field is No. The value is updated to Yes after you successfully run pdm_configure on that server. If you edit any of the automatically entered field values of a server record, the Configured field turns to No.

Configure the Standby or Application Servers

You configure each standby and application server after configuring the background server. This configuration is required to establish communication with the background server.

Important! (Recommended) Ensure that both background server and all other standby servers have similar configuration. This process ensures that during a failover when a standby server becomes the new background server, it can function exactly like the old background server.

Follow these steps:

  1. (If you are adding a new standby or application server) Ensure that you added the server record of the standby or application server that you are configuring. For more information, see the Add a Server section.
  2. Log in to the server that you want to configure as the standby or application server.
  3. Use the pdm_configure command to start the configuration.
    The Select Server Configuration screen opens.
  4. Select Advanced Availability as the configuration type and follow the prompts to complete the configuration. To enable and use the federated search feature, select the federated search option. For more information, see Server Configuration Utility
  5. Repeat steps 1-3 on each of the servers that you want to configure as the standby and application server.
    You have configured the standby and application servers.
  6. Suppose that you have one or more application servers. You can configure a load balancer to track the requests to and from the different application servers.

    Note: To use a load balancer URL or an application server URL for the links in the CA SDM notifications, complete the following steps:
    1. Log in to the background server.
    2. Select Options ManagerNotifications on the Administration tab.
    3. Change the value of the web_cgi_url option to point to:
      • The load balancer if you have more than one application servers.
      • The application server, if you have only one application server.

Verify the Server Details

After you have configured all the servers, ensure that each one is properly configured and available.

Follow these steps:

  1. Make sure that all background, standby, and application servers are running.
  2. Log in to the background server Web UI.
  3. Select SystemServers on the Administration tab.
    The Server List page opens.
  4. Verify that the Configured field displays Yes for the standby and application server records.
  5. If Record Status is set to inactive, edit the server and set to Active. If you change the record status of any server, reconfigure it.
    You have successfully configured servers for the advanced availability configuration.

    Note: You can click any of the Local Host entries on the Server Details page to view the details of the server.
