Hi,
The ORA 12154 makes me suspect that VLCDB is being considered as a TNS
alais - and was not found in any tnsnames.ora that your client env
variables pointed to. So you might need to:
- make a tnsnames.ora if not done so already
- set TNS_ADMIN to point the the dir it is in
Alternatively I think you can use the JDBC style connect descriptor e.g
://hostname/SID in your CREATE SERVER command.
regards
Mark
