Scanning system prerequisites for Tivoli Workload Scheduler
Before installing or upgrading the product, Tivoli Workload Scheduler automatically runs a scan on your system.
About this task
Having an environment that meets the product system requirements ensures that an installation or upgrade succeeds without any delays or complications.
The scan verifies that:
- The operating system is supported for the product.
- On UNIX operating systems, the necessary product libraries are installed.
- There is enough permanent and temporary disk space to install both the product and its prerequisites.
- There is enough memory and virtual memory.
Note: The scan verifies only that the environment meets the requirements
of Tivoli Workload Scheduler.
It does not check the requirements for other components, such as DB2®. To verify the requirements
for Installation Manager use
the procedure described in Scanning system prerequisites for Installation Manager.
If
any of these checks fails, Tivoli Workload Scheduler performs
the following action:
- For all the components installed by using Installation Manager:
- Displays a notification of the requirement that was not met. In this case, stop the installation or the upgrade, analyze the log files, solve the error, and rerun the installation or upgrade. If you are performing an interactive installation, the errors are displayed on the screen. If you are performing a silent installation, the errors are written in the Installation Manager log files. For more information about log files, see Installation Manager wizard, silent installation and uninstallation log files.
- For agents
- If you specified the stoponcheckprereq parameter,
the twsinst script does not proceed. In this case,
analyze the log file, solve the error, and rerun the installation
or upgrade. The log files are located:
- On Windows operating systems:
- %TEMP%\TWA\tws92\result.txt
- On UNIX and Linux operating systems:
- $tmp/TWA/tws92/result.txt
