Is anyone installed windchill 12 using Oracle 18c Express Edition

 Hi,

1. Read the following articles:

• "PSI validation failed in define settings "Failed to validate the Oracle Home User Password with the username found in the registry" for Windchill PDMLink 10.2 M030": https://www.ptc.com/en/support/article/CS201974
• "PSI fails to validate Oracle Home User password when installing Windchill PDMLink with Oracle 12c database": https://www.ptc.com/en/support/article/CS213330

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-p/740351

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?
