Issue with the application process. previously i had multiple client. I have removed all the version of oracle client from app server and not getting issue of

System.TypeInitializationException: The type initializer for 'Oracle.DataAccess.Client.OracleConnection' threw an exception. ---> System.DllNotFoundException: Unable to load DLL 'OraOps18.dll': The specified module could not be found. (Exception from HRESULT: 0x8007007E)
at Oracle.DataAccess.Client.OpsInit.CheckVersionCompatibility(String version)
at Oracle.DataAccess.Client.OracleInit.Initialize()
at Oracle.DataAccess.Client.OracleConnection..cctor()
--- End of inner exception stack trace ---

I have only oracle 19 and odac on the server now..

any suggestion would help!!!

Relink your application with the correct DLL or modify the source code to ask this later one.
