Administrative tasks
This chapter describes how to perform some specific administrative
tasks on HCL Workload Automation,
as follows:
- The tasks
-
- Switching a 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.
- Switching the master to a backup
- 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 properties for the database
- 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 WebSphere Application Server Liberty Base
- Managing the event processor
- If you are using event-driven workload automation, you will need to perform periodic maintenance on the event processor.
- 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 - 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 based on templates whereby you:
- Copy the template file from the templates folder to a working folder.
- Edit the template file in the working folder with the desired configuration.
- Optionally, create a backup copy of the relevant configuration file present in the overrides directory in a different directory. Ensure you do not copy the backup file in the path where the template files are located.
- Copy the updated template file to the overrides folder. Maintaining the original folder structure is not required.
- Changes are effective immediately.
