This is not a DBI issue. However, from oerr:
$ oerr ora 12514 12514, 00000, "TNS:listener could not resolve SERVICE_NAME given in connect descriptor" // *Cause: The SERVICE_NAME in the CONNECT_DATA was not found in // the listener's tables. // *Action: Check to make sure that the SERVICE_NAME specified is correct. // *Comment: This error will be returned if the (database) service has not been // registered with the listener; a database instance that is part of this // service may need to be started or configured properly. This means one of several things: 1. Your parameter 'local_listener' is incorrect or non-existent. 2. Your sqlnet.ora parameter names.default_domain is not correct. 3. You have the TNS_ADMIN env variable set. 4. You have an error in your tnsnames.ora file. So, what does your sqlnet.ora look like? Can you connect via SQL*Plus from the machine where you are having these issues? You need to consult with your DBA. ----------------- Ron Reidy Lead DBA Array BioPharma, Inc. -----Original Message----- From: Kairam, Raj [mailto:[EMAIL PROTECTED] Sent: Wednesday, March 23, 2005 12:25 PM To: [email protected] Subject: Unable to connect to Oracle on another Unix host in a perl programming using DBI To those who could help me with a problem connecting to an Oracle database on HP-UX from within a perl script that uses DBI I have a perl program on a unix (HP-UX) host(A) running Oracle 8.1.6 In the program I am trying to connect to another unix (HP-UX) host(B) running Oracle 8.1.7 holding a table c1dwg.
