A few days back, while installing Oracle database software on one of out UAT server I faced this issue.
While verifying target environment for minimum requirements, runIstaller failed with error given in screenshot below:
After searching on metalink, I found : Failed to initialize GPnP Reported While Executing oifcfg (Doc ID 1050472.1).
As per this note, this issue occurs due to wrong ORA_NLS10 Setting.
So as to resolve the issue, you can use one of the following method:
1. export ORA_NLS10=$GRID_HOME/nls/data
2. unset ORA_NLS10
In my case, reruning runIstaller after unsetting ORA_NLS10 resolved my issue.
Hope so u will find this post very useful 🙂
