Centralized configuration for the mid tier

Centralized configuration refers to storing configuration form data at a common location that can be accessed by other computers. Centralized configuration simplifies the management of configuration data and the sharing of configuration settings across servers. For more information, see Centralized configuration.

You must configure a BMC Remedy AR System server to act as a Centralized Configuration Server (CCS). The Centralized Configuration Server is a BMC Remedy AR System server that does not have any applications installed or any end-user interactions. Centralized Configuration Server needs limited resources in terms of CPU and RAM.

The Centralized Configuration Server ensures consistency by communicating changes to the global properties across all the mid tiers in a cluster. If a configuration server is defined while adding a tenant, that tenant configuration server maintains a copy of the tenant-specific settings. When a tenant-specific property is modified on one mid tier, the Tenant Configuration Server automatically sends the notification to other mid tiers that have the same tenant added, so that these configuration changes are also synchronized by each mid tier in the same cluster.

For example, you have 10 mid tiers in a cluster. Before centralized configuration, each tenant was managed independently. To change a configuration setting, you had to make the same change for each tenant in the cluster. With centralized configuration, because all settings are stored in forms, you can change the settings for multiple tenants in a cluster at one time. Centralized configuration enables you to share configuration settings across all tenants in a cluster.

Centralized configuration 



If you are using a version of BMC Remedy AR System server earlier than 20.14.01 and cannot set Centralized Configuration Server and Tenant Configuration Server, you must manually update the global and tenant-specific settings for all the mid tiers in the cluster. Use the Mid Tier Configuration Tool to update the settings. If you do not have access to the Mid Tier Configuration Tool, edit the and tenants/ files.

To set the Centralized Configuration Server properties

  1. Open the BMC Remedy Mid Tier Configuration Tool from the URL: http://hostname:port/arsys/shared/config/config.jsp.
  2. Click Central Config Settings.
  3. In the Central Config Settings page, enter the following information:
    1. In Server Name, enter the name of the AR System server that is the designated as the Centralized Configuration Server in the cluster.
    2. In Cluster ID, enter the unique cluster ID of the cluster to which the mid tier belongs.
    3. Enter the administrator password.
    4. (Optional) Enter the port number and RPC number.
  4. Click Save.


    You can configure a BMC Remedy AR System server as a Centralized Configuration Server or a Tenant Configuration Server only if the AR System server version supports centralized configuration and has the configuration-related system forms and notification capability.

  5. Click Publish to create or update global properties from the file to Centralized Configuration Server.


    After you publish, properties that are deleted from the file are not deleted from the Centralized Configuration Server. However, deleted properties are reflected in the current mid tier memory immediately and are restored when the mid tier is restarted. Click Restore to restore global settings from the Centralized Configuration Server to the file. Exercise caution when deleting any property directly from the Centralized Configuration Server forms.

  6. Click Restore to update the global settings from Centralized Configuration Server to the file.


The properties that are not available for editing through the Centralized Configuration Settings page must be edited directly in the file.

 A file is added to the midTierInstallationDirectory\WEB-INF\classes folder and contains the following information:

    The cluster identifier of the mid tier cluster. All mid tier instances in the same cluster share the cluster identifier.
  • arsystem.ccs.password
    The encrypted mid tier service password for the Centralized Configuration Server.
    The name of the Centralized Configuration Server.
  • arsystem.ccs.port
    The port number of the Centralized Configuration Server.

The mid tier uses the file for connecting to the Centralized Configuration Server on startup and for updating its configuration files for global settings ( and tenant-specific settings (


If you have configured a valid Centralized Configuration Server or Tenant Configuration Server, refrain from making any changes directly to the properties files. These changes might be overwritten during the next mid tier restart. Make all the necessary changes in the BMC Remedy AR System Configuration Component Setting form on the Centralized Configuration Server or Tenant Configuration Server, using the appropriate cluster ID or tenant name. The changes will take effect in all concerned mid tier instances and corresponding properties files by means of a periodic notification (typically after 30 seconds). However, changes to some of the properties, such as Ehcache settings and number of threads, require the mid tier to be restarted. For more information, see Centralized configuration.
