Oracle 18c installation-Prerequisite checks fails-PRVG-0282 : failed to retrieve the operating system distribution ID

Problem :

During Oracle 18c installation while running prerequisites check it fails with below error .

“PRVG-0282 : failed to retrieve the operating system distribution ID”

The command used was: ./RUNINSTALLER -ohcheck

Next step and resolution :

• Check if your Oracle18C is supported with your operating system version and check oracle documentation for supported version mapping.In my case i was getting error on SLES 12 SP 03 which is supported to oracle 18c.
• If you are on supported version of operating system then set below parameter to ignore this error:

CV_ASSUME_DISTID=SUSE12   parameter in the /oracle/<SID>/18.0.0/cv/admin/cvu_config file.  in case of  oracle 18c  .

[If you are getting error in case of oracle 12C prerequisites check then set CV_ASSUME_DISTID=SUSE12 parameter in database/stage/cvu/cv/admin/cvu_config file and retry. ]

• Re-execute  ./RUNINSTALLER -ohcheck , it will pass.
