Using Tivoli Decision Support

Tivoli Decision Support (TDS) for Storage Management Analysis is a separate program product that works with Tivoli Storage Manager to let you strategically manage your enterprise network. Storage Management Analysis helps you make decisions concerning storage management by providing an overview of your system performance and resource usage. Using data collected from TSM servers, Storage Management Analysis displays multidimensional views and detailed reports.

Storage Management Analysis requires the Tivoli Storage Management Decision Support Loader, which runs daily to collect and aggregate the data into the database table. See Scheduling the Decision Support Loader with Tivoli Storage Manager for information about automating the scheduling of Decision Support Loader runs. The Tivoli Discovery Administrator interface is used to define queries that extract data from the TDS database into a file. Cognos Transformer builds a cube from the file, and Cognos PowerPlay generates reports from the cube. You can use the Tivoli Discovery Interface to view these reports. You can also use Crystal Reports to generate text-based views.

To use Storage Management Analysis on your TSM server or servers, you must first enable event logging of client events to the activity log. See Logging Events to the Tivoli Storage Manager Server Console and Activity Log for details.

Scheduling the Decision Support Loader with Tivoli Storage Manager

You can schedule the Decision Support Loader (DSL) to run automatically using the TSM Scheduler. Before defining a schedule, ensure that the backup-archive client is installed on a dedicated Windows workstation where the DSL is installed.

Use the following procedure to schedule the DSL:

  1. On the TSM server:
    1. Register the client node. Assume that the client node you registered is called ASTROdsl.
    2. Define a client schedule on the server from which the DSL will extract data. For example, if the schedule is called TSMDSL and client node ASTROdsl is registered in the STANDARD domain, enter:
      define schedule standard tsm_dsl action=c 
      object='"c:\program files\tivoli\tsm\decision\tsmdsl"'
      

      Notes:

      1. The installation directory path for the DSL is:
        "c:\program files\tivoli\tsm\decision\tsmdsl.exe"
        

      2. Enclose the full directory path in quotation marks as shown in the previous example.
    3. Associate the client node to the tsm_dsl schedule. For example:
      define association standard tsm_dsl ASTROdsl
       
      
  2. On the client's workstation:
    1. Ensure that the scheduler is installed.
    2. Start the scheduler for the client. Leave the scheduler running until scheduled rollups are no longer needed. To start the scheduler, you can open a command prompt window and navigate to where the backup-archive client is installed and enter:
      > dsmc schedule
      
Note:
If the DSL is not processed according to the schedule you have defined, check the directory path where the DSL is installed.
