Scanning system prerequisites on IBM i systems

Before you install or upgrade the agent, IBM Workload Scheduler automatically runs a scan on your system. Having an environment that meets the product system requirements ensures that the installation or upgrade succeeds without any delays or complications.

The scan verifies that:

The operating system is supported for the product.
There is enough permanent and temporary disk space to install both the product and its prerequisites.
There is enough memory and virtual memory swap space.

Note: The scan verifies only that the environment meets the requirements of IBM Workload Scheduler.

If any of these checks fails, IBM Workload Scheduler performs the following action:

An error message is returned. Analyze the log file, solve the error, and rerun the installation or upgrade. The log file is in %TEMP%\TWA\tws1024\result.txt
You can decide to rerun the installation or upgrade without executing the prerequisite scan. If you specify the -skipcheckprereq parameter, the twsinst installation script does not execute the prerequisite scan. For more information about the -skipcheckprereq option, see Agent installation parameters - twsinst script.
