Getting ORA-12557: TNS:protocol adapter not loadable from ASP.NET Web Application

in Database ORA-600 / ORA-7445 Analysis , Diagnostic Repository (ADR) & Packaging (MOSC) 1 commentAnswered

ASP.NET application is built using 11g Oracle Data Access libraries but backend Oracle database is being upgraded to 19c. Oracle client 11g 32-bit, 11g 64-bit and 19c instant client have been installed on the server. I tried setting oracle home to 11g clients but still getting ORA-12557: TNS:protocol adapter not loadable from the web application. Any suggestions to try? Thanks
