connecting to remote oracle via cygwin sqlplus

Question

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?

Answer 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.

Answer 2

There isn't a cygwin Oracle client. As above answer, use the ORACLE_HOME set to the windows path.

For the first half of your question, try seeing what the TNS_NAMES env variable is set to, and if not set, you may need to try setting it to the correct place. Usually it defaults to %ORACLE_HOME%/network/admin/tnsnames.ora . SQL Developer keeps it's own copy of the tnsnames file, so you can't reply upon that to fix the problem.

Answer 3

^{Combining the details from the other answers (which took me a little, so I post it as separate answer instead of comments):}

The $ORACLE_SID and, if set, $TNS_ADMIN (and probably other path-related Oracle variables) must use Windows-paths. Your Cygwin $PATH variable should of course use the Cygwin notation (/drives/c/…). So I've included into my .bashrc:

export ORACLE_HOME=c:\\Oracle\\product\\12.1.0\\dbhome_1
export TNS_ADMIN=d:\\Oracle\TNSAdmin
export PATH=$PATH:$(cygpath -u $ORACLE_HOME)/BIN

After that, I had no more issues calling e.g. tnsping or sqlplus. As the above is just an example, you must of course adjust the paths to reflect your installation/configuration :)

Answer 4

NXC is right - it wasn't a cygwin client I was using, but the windows sqlplus client. I set the windows environment variables for ORACLE_HOME and ORACLE_SID and was then able to run sqlplus in a cygwin bash shell using the net_service_name from tnsnames.ora.

Answer 5

The way it worked for me was to remove /cygdrive/d or /cygdrive/c and replace them with with d:/ or c:/ and then your sqlplus call within cygwin session will work. The /cygdrive/DriveLetter is confusing it.

Answer 6

I have same error like you,

you should set not only ORACLE_HOME in windows Variables,

But also PATH include %ORACLE_HOME%\bin

then you can open windows cmd,

try sqlplus username/password@your_define_tnsname

if okay, then remove all ORACLE PATH setting in cygwin, restart cygwin,try it.

if failure, should let sqlplus works well in windows cmd at first
