\u00a0A few times over the course of working with Oracle, I’ve come across environments which had issues making connections to databases set up across a network. These were failing with the error “ORA-12514: No TNS Listener”.<\/p>\n

I eventually found that to fix this, you need to follow the steps below:<\/p>\n

    \n
  1. Install the Oracle Data Access Components (ODAC)<\/a>\u00a0on the machine attempting to make the connection<\/li>\n
  2. Navigate to C:\\app\\<username>\\product\\<oracle_version>\\client_1\\Network\\Admin\\Sample (note that this is a Windows 7 path – it will differ for other OS’s)<\/li>\n
  3. Copy tsnames.ora into the directory one above it<\/li>\n
  4. Open it up and replace all the values in angle brackets with the correct values for your set up:<\/li>\n<\/ol>\n
    <data source alias> =\n (DESCRIPTION =\n (ADDRESS = (PROTOCOL = TCP)(HOST = <hostname or IP>)(PORT = <port>))\n (CONNECT_DATA =\n (SERVER = DEDICATED)\n (SERVICE_NAME = <database service name>)\n )\n )<\/pre>\n
    Best of luck!<\/p>\n","protected":false},"excerpt":{"rendered":"
