Issue/Introduction

When I run the R12 DVD iso file on AWS Linux -2 OS to install Workload Automation Autosys components, the following error is encountered during OS validation and installation is aborted:

Error:

[CAUAJM_E_110025] This operating system is not supported for AutoSys
installation. For a list of supported operating systems, refer to AutoSys
Suppport Matrix.

PRESS <ENTER> TO ACCEPT THE FOLLOWING (Quit Installation):

 

Environment

Release : 11.3.6 and above(Linux and Windows)

Component : CA Workload Automation AE (AutoSys)

Resolution

1. Logon to the server as the root user.
2. Set the environment variable SKIP_PRE_CHECKS=1 from the command line, as the root user. This will bypass the OS validation checks.
3. Launch the installer script and choose the appropriate product for installation and respond accordingly to the prompts to suit your environment.

Additional Information

If the installer continues with the same behavior,  verify if cawa_installer.log has info like this:

If so, another way to get around this issue is by below approach:

1) /etc/profile ==>   make a backup this file first

2) edit the file and add:

SKIP_PRE_CHECKS=1

export SKIP_PRE_CHECKS

3) Save the file

4) Restart the installer
