also happen if your firewall has disconnected idle connections.Also, the ORA-12537 sometimes happens in these cases: 1. You have a path name that is too long for the Oracle TNS client. See MOSC note:263489.1. Since the iORA-12537 ssue is caused by a large connection string there are several workarounds for the issue. 1. Install the exe in a shorter named directory. 2. Modify the TNS Names entry so that it is shorter. 3. Replace domain names with IP Addresses if that shortens and vice versa. 4. Remove any parameters from the entry that are not needed. 5. Patch the Database Listener to the most recent version. References 2. Bug:1566794: CONNECTIONS FAIL WITH ORA-12537 WHEN USE_SHARED_SOCKET IS SET IN 8.1.7.
