HCL Workload Automation, Version 9.4

Administrative tasks

This chapter describes how to perform some specific administrative tasks on HCL Workload Automation, as follows:
The tasks
Changing a domain manager or dynamic domain manager
Change a domain manager or dynamic domain manager, either in the event of the failure of the computer where it is installed, or as part of a planned replacement activity.
Changing a master domain manager
Change a master domain manager, either in the event of the failure of the computer where it is installed, or as part of a planned replacement activity.
Changing key HCL Workload Automation passwords
Change the password of the TWS_user, or any other of the users that have an infrastructure role in HCL Workload Automation.
Unlinking and stopping HCL Workload Automation
The correct procedure to unlink the master domain manager from its agents and stop the master processing.
Changing the database host name, port, or database name
If you need to change the host, port or name of the database, effect the change in the application server, where the data source configuration is maintained.
Changing the workstation host name or IP address
Change the host name or IP address of a workstation.
Changing the security settings
If you need to update the properties that define your SSL connection or authentication mechanism, you need to make the changes in the embedded WebSphere Application Server
Managing the event processor
If you are using event-driven workload automation, you will need to perform periodic maintenance on the event processor.
Starting, stopping, and displaying dynamic workload broker status
The procedure to start or stop dynamic workload broker.
Application server tasks
The following tasks might need to be performed on the application server:
Application server - starting and stopping
How to stop and start the application server when you need to.
Application server - automatic restart after failure
The application server is managed by a utility that restarts it if it stops for any reason (subject to a configurable policy). This section describes how to modify the policy and deal with any situations that the policy cannot handle.
Application server - encrypting the profile properties files
Several of the application server configuration files contain passwords. To avoid that these remain in the files in plain text, run a utility to encrypt them.
Application server - updating the Windows services after modifications
On Windows, after changing certain data you must also update the Windows service that runs the embedded WebSphere Application Server.
Application server - updating the SOAP properties after changing the WebSphere Application Server user or its password
On UNIX or Linux operating systems, if you have changed the user ID or the password of the WebSphere Application Server administration user either for HCL Workload Automation or the Dynamic Workload Console, you must also update the SOAP client properties.
Application server - configuration files backup and restore
The application server configuration manages the data source and security aspects of your HCL Workload Automation environment. The files should be regularly backed up and when necessary can be restored.
Application server - changing the host name or TCP/IP ports
If you need to change the host or ports used by the application server, follow the correct procedure.
Application server - changing the trace properties
The application server has a trace facility. This section describes how to increase the trace level to obtain more information for troubleshooting, and how to reduce the level to improve performance.
Changing the application server properties
Several of the above tasks require you to run a common procedure whereby you:
  1. Run a utility that displays a set of current application server properties and saves them to a file
  2. Edit the file to change the properties
  3. Run another procedure to update the application server with the changed properties
This procedure is fully described in Application server - using the utilities that change the properties
Application server utilities reference information
Some reference information on the application server utilities is also provided in Application server utilities. For further reading, see IBM® Redbooks®: WebSphere® Application Server V6 System Management & Configuration Handbook.
