PURPOSE

The intent of this document is to provide a guide to setup the TSM Client Acceptor (CAD) Service to control the TSM Scheduler Service in a Windows environment.  

REFERENCE

Please contact the Champion Managed Services Operations Manager to clarify any process within this procedure and for any concern beyond its scope.

OVERVIEW

The TSM Scheduler Service has historically been unstable in a Windows environment in the regard that the service periodically needs to be reset.  The method of using the TSM Scheduler Service on demand improves the reliability of backups that reflect “Missed” on the TSM high level backup report due to the Scheduler requiring a restart.  The method of using the TSM Scheduler on demand is done by setting up the TSM Acceptor Service to manage the TSM Scheduler.

This setup process requires Administrator rights to the Client Server running the TSM Services, plus a TSM administrative account on the TSM Server that has access privilege to update a client node.

PROCEDURES

  1. Stop TSM Scheduler Service

  2. Stop TSM Journal Service

  3. Stop TSM Client Acceptor (CAD)

  1. Edit the file C:\Program Files\Tivoli\TSM\baclient\dsm.opt.

  2. Add the following entry to the file:

MANAGEDSERVICES SCHEDULE

  1. On the TSM Server, type the following command:

update node node_name password passexp=0

where node_name is the name of the server, and password is the same as the node_name.

  1. On the TSM Client, navigate to C:\Program Files\Tivoli\TSM\baclient, and then enter the following command:

dsmcutil update CAD /name:”TSM Client Acceptor” /CADschedname:”TSM Scheduler” /Node: node_name /Password: node_name /Autostart:yes

where both instances of node_name are the name of the sever defined in Step 6.

  1. Start the TSM Acceptor Service.

  2. Start the TSM Journal Service.

WARNING:  DO NOT start the TSM Scheduler Service.

This completes the procedure.

The following is an example of the results of the command explained in Step 7 above.  The actual results may be slightly different.

Command:

C:\Program Files\Tivoli\TSM\baclient>dsmcutil update CAD /name:"TSM Client Acceptor" /CADschedname:"TSM scheduler" /Node:usga21as11 /Password:usga21as11 /Autostart:yes
