  • For ALTIBASE HDB 5.3.3 or above, backward compatibility for the server and client is supported.


  •  The client can connect to a server of the same or newer version regardless of its cm protocol version whereas, connection fails if the client is of a newer version than the server.


  • In this context, the first three numbers of a product version are denoted as the version (the fourth and succeeding numbers which indicate the patch versions are irrelevant).

Server Version

Client Version



Server Version > Client Version 
(5.3.3 and or above)




Backward compatibility is supported for 5.3.3 and or above.

Server Version > Client Version 
(5.3.1 and or below) 




Backward compatibility is supported only if the version of both the server and client is 5.3.3 and or above. 
Since the client version is older than 5.3.3, backward compatibility is not supported. For 4.3.9, connection succeeds only if the cm protocol versions are the same.

ServerVersion < Client Version 




If the version of the client is newer than the server, connection fails regardless of the Altibase version. 
The version of the client must be the same or older than the server.
