Did you ever figure this out? I think the SID case (upper/lower) has to match the Case of the name in the Service.

Useful questions from lots of people - I will try to answer them all here:
- This is a two-node RAC. Node 1 - everything works as expected. Only on node 2 do we see this weirdness.

  • There have been no new software installs.
  • There are multiple homes installed - these boxes started life as, so the old homes are present but nothing runs from them.
  • The service on this node is OracleServiceMMP52
  • The current DB Home is the first entry in the %PATH% - that's where sqlplus runs from.
  • No errors in the alert log or listener log. Unfortunately, this is an issue because our backups run on node 2, and our backup scripts all use "RMAN TARGET /" - this is failing too...

Hey list,

This is backwards enough that I don't quite know where to start with it. This morning we noticed that for one environment, we cannot make direct local connections... but we can connect to our hearts' content via the listener. I'm used to seeing the listener act up and being able to connect directly but not via the listener - not this.
