Upgrading agents and domain managers with twsinst

How to upgrade HCL Workload Automation agents and domain managers in your distributed, z/OS®, or end-to-end network.

The upgrade of agents and domain managers is supported starting from V9.3. The agent upgrade process meets the following objectives:

Performs the upgrade in a safe way: It checks for any processes or command lines that are running before starting. It stops them only for the short time necessary to perform the upgrade. If the upgrade fails, a backup and restore feature is in place.
Saves time, disk space, and RAM when upgrading the product: It performs the agent upgrade in less time than traditional methods. It saves disk space and RAM because it is not Java-based.
Uses a very simple command: It consists of a single line command.
Manages both Windows™ and UNIX™ operating system workstations: It runs on both Windows™ and UNIX™ agents.

Use the twsinst script to upgrade the HCL Workload Automation agent in your distributed or end-to-end network.

For information about upgrading agents, see Upgrade procedure. See Agent installation parameters - twsinst script for a full description of the agent installation parameters used by the script.
