Client unable to establish connection / Communication link failure

In the following cases, a client unable to establish a connection error occurs. (Communication link failure may occur depending on the version.)
  • ALTIBASE server is not running
  • If the connection is impossible because the IP address or port number of the ALTIBASE server is incorrectly set in the connection URL

The following is an example of the case where the IP address of the ALTIBASE server to be integrated is 192.168.1.81 and the port number is 20300, and it is incorrectly specified as a different value.

Code Block
jdbc:Altibase://192.168.1.80:20800/mydb


Hang phenomenon

If the user tries to connect while the ALTIBASE JDBC driver and the CM protocol version of the ALTIBASE server are different, a phenomenon such as hang may occur depending on the WebLogic version.

When this happens, most of the WebLogic server instances have to be restarted, so caution is required in advance.

For related information, refer to How to Check the ALTIBASE JDBC Driver Version.
