I configured BizTalk 2020 Server with CU1 and I installed Oracle Client in this way.
But, when I'm going to change configuration, I receive this error Any suggestion?
Problem was that I installed Oracle.DataAcces(x64-x86) through gacutil. You should install dll with: oraprovcfg.exe /action:gac /providerpath:Oracle.DataAccess.dll that supplies to put dll in gac and change machine.config.
From version 18c , Oracle Client don't install automatically dll in gac and don't update
machine.config
