Scanning system prerequisites for IBM Workload Scheduler
Before installing or upgrading the product, IBM Workload Scheduler automatically runs a scan on your system.
bc
executable is present on the local system and that it is set
in the PATH environment variable. If you do not want to install the
bc
executable, you can skip the prerequisites check by using
the skipcheckprereq parameter when running the
serverinst and twsinst parameters. For
more information about the bc
executable, see bc, an arbitrary precision calculator language. For more
information about installation commands, see Master components installation - serverinst script
and Agent installation parameters - twsinst script.Having an environment that meets the product system requirements ensures that an installation or upgrade succeeds without any delays or complications.
- 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.
If any of these checks fails, IBM Workload Scheduler returns an error message.
- On Windows™ operating systems:
- <TWA_home>\logs\serverinst<version_number>.log
- On UNIX and Linux™ operating systems:
- <TWA_DATA_DIR>/installation/logs/serverinst<version_number>.log
- On Windows operating systems:
- <DWC_home>\logs\dwcinst<version_number>.log
- On UNIX and Linux operating systems:
- <DWC_DATA_dir>/installation/logs/dwcinst<version_number>.log
- On Windows operating systems:
- <TWA_home>\logs\twsinst<interp><user_name><version_number>.log
- On UNIX and Linux operating systems:
- <TWA_DATA_DIR>/installation/logs/twsinst<interp><user_name><version_number>.log
You can decide to rerun the installation or upgrade without executing the prerequisite
scan. If you set the -skipcheckprereq parameter to true
when performing the installation, the installation script does not execute the prerequisite scan. If
a problem occurs, an error is displayed, the component is installed or upgraded, but might not work.
For more information about the -skipcheckprereq
parameter in all installation
scripts, see Reference.
Starting from version 9.5, Fix Pack 2, the prerequisite scan no longer verifies the presence on the local system of 32-bit libraries. However, the extended agent for MVS requires a set of libraries on Linux PPC. You can find the updated list of libraries, in addition to a detailed list of supported operating systems and the most up-to-date product prerequisites, in IBM Workload Scheduler Detailed System Requirements.
