I’m trying to install Oracle on a linux machine to be accessed on Cobol. sqlplus is working, I can execute sql commands.

While trying to start the Oracle System, I am getting the error:

Message 1070 not found; No message file for product=network, Facility=TNSTNS-12545:

I have tried several configurations of the files Listener.ora and tnsnames.ora, but I can’t start from Listener. I’m working on a linux machine with no graphical option.

The ultimate goal is to run a program on Microfocus Cobol accessing an oracle table.

Caro Orlando,

The Listener.ora file may be in the wrong location or does not have the correct permissions.

Make sure you’re on your way: $ORACLE_HOME/network/admin

The file owner must be [oracle-user]. [oracle-group]

Permission must be 644

If you check that everything is correct try to configure the system through the netca.

  • First of all thank you very much. The only situation that was not done was "The owner of the file should be [oracle-user]. [oracle-group]", I already made the change and the same error continues. As for netca I think it is in graphical environment that my machine has not installed.

  • Orlando! You can use the smartty (http://smartty.sysprogs.com/) that has the embedded Xming to run the netca

  • Actually the $ORACLE_HOME variable had an extra directory.
