  • 0

I’m trying to use cygwin sqlplus to connect to a remote oracle installation located at myserver.mycompany.com port 1530. When I try

sqlplus username@myserver.mycompany.com:1530/orcl

I get the error:

ORA-12154: TNS:could not resolve the connect identifier specified

When I set ORACLE_HOME to /cygdrive/c/oracle/product/10.2.0/client_1, I get a different error:

Error 6 initializing SQL*Plus Message file sp1<lang>.msb not found SP2-0750: You may need to set ORACLE_HOME to your Oracle software directory

I can telnet to the server’s port 1530, and the SQL Developer installed locally is also able to connect to the database. What am I doing wrong?

  1. I wasn’t aware there was a native cygwin client for Oracle (correct me if I’m wrong here but I can’t find any mention of it on Oracle’s web site either). If you’re using Cygwin with the Windows client you need to use a native windows path. It won’t understand your /cygdrive path.

    However, I have used Win32 Oracle clients with cygwin and made it work – the same shell scripts would work on Cygwin, Linux and Solaris.
