Connection from ALTIBASE HDB client to Altibase server fails.
An error may occur in the following two cases. In the version, the first three digits are the major version, and the back digits are the patch version.
When the major version of the server and the client are the same, but the patch version of the client is later than that of the server.
When the client's major version is later than the server's major version.
When error occurs within the same major version
ALTIBASE HDB 5.5.1
When connecting to a server with a version earlier than 220.127.116.11.7 from a later version including ALTIBASE JDBC DRIVER version 18.104.22.168.7, the connection fails. (Example, JDBC driver version 22.214.171.124.7 -> ALTIBASE HDB server 126.96.36.199.6)
When connecting to a server with a version earlier than 188.8.131.52.10 from a later version client including 184.108.40.206.10, the connection fails. (Example, iSQL version 220.127.116.11.10 -> ALTIBASE HDB server 18.104.22.168.9)
This error occurs when a client connects to the server and requests a server property that the server does not know.
At the time of connection, the client requests the server properties necessary for client configuration to the ALTIBASE HDB server.
However, when a server property is added from a later version and a later version of the client connects to the lower version, an error occurs as follows.
Use the same or earlier version of the client as the ALTIBASE HDB server.
In order to use a later version of the client, the ALTIBASE HDB server version must also be patched or upgraded to the same version.
