I've been running into some problems getting my Oracle installation up and running on Windows Server 2012 r2 at work. Initially, I had installed Oracle on my Win10 laptop for test purposes - I connected to it using Toad for Oracle and had no problems.
However, after installing on Windows Server 2012 r2 I noticed that there were no control files and/or database files in the
%ORACLE_BASE%\oradata\XE directory. In addition, I noticed that my
listener.ora file was missing an entry for the XE service instance - once this was added, I could connect via SQLPlus but then the database could not be mounted because there were no control files. I even tried using DBCA to create a new database but ran into invalid memory parameter issue.
I'm starting to wonder if 18c is even compatible with Server 2012 r2 even though the documentation says it is - am I missing some configuration? Any help would be greatly appreciated - I've been trying to figure this one out for the last few days. Thanks.
