instType uknown

Started getting this error from a batch job which was using oradim to do a shutdown.

instType uknown: db not started; use RDBMS as default

I think this has just been occurring since we put a 10G install on the same server as the existing 9i and 8i databases.

Anyhow it was fixed by explicitly setting ORACLE_HOME and prefixing oradim with %ORACLE_HOME%bin
