jConnect version for HA functionality

[ameliavinluan]

Hello - would like to inquire what jConnect version supports HA functionality when connecting to ASE 16?  Thanks!

You tagged your question with SAP Java Connector, which I don't think has anything to do with your question.

I have added the tag for the SAP ASE database. Perhaps the people over there understand your question?! But as Stefan already mentioned: "jConnect" does not seem to have anything to do with "JCo" (which is used for RFC communication and not for JDBC/database connectivity).

jConnect 16.0 from SDK 16.0 SP03 and higher will support HADR (Always On) operations as documented at SAP jConnect Features for HADR.

My recommendation would be to use the jConnect version matching the base ASE release, or higher.  If you use a higher jConnect release, remember to install the corresponding sp's - remember, jConnect is two parts - thin java driver AND sp installation).

If you have jconn42.jar available, use that .jar, not jconn4.jar for JDBC 4.2 support and ongoing development (only jconn42.jar will be released in future SDK and ASE releases).  The Programmers Reference gives examples of how to use this (it's only a change to the class being called).
