Im installing the windchill 12 but im facing a error as "Failed to validate the Oracle Home User Password with the username found in the registry."
1. Read the following articles:
2. There was a similar question before - "Failed to validate the Oracle Home User Password with the username found in the registry": https://community.ptc.com/t5/Windchill/Failed-to-validate-the-Oracle-Home-User-Password-with-the/td-...
That did not work
You can open a new "Case", here: "Case Logger": https://support.ptc.com/apps/case_logger_viewer/cs/auth/ssl/log
I think I read a note in the support matrix about 18C being soon to be deprecated. I would think you might want to move to 19c, right?
