DB2 10.5 for Linux, UNIX, and Windows
DB2 10.5 for Linux, UNIX, and Windows
The compatibility of a particular version of the IBM® Data Server Driver for JDBC and SQLJ with a database version depends on the type of driver connectivity that you are using and the type of data source to which you are connecting.
The IBM Data Server Driver for JDBC and SQLJ is always downward compatible with DB2® databases at the previous release level. For example, IBM Data Server Driver for JDBC and SQLJ type 4 connectivity from the IBM Data Server Driver for JDBC and SQLJ version 3.61, which is shipped with DB2 for Linux, UNIX, and Windows Version 9.7 Fix Pack 3, to a DB2 for Linux, UNIX, and Windows Version 8 database is supported.
The IBM Data Server Driver for JDBC and SQLJ is upward compatible with the next version of a DB2 database if the applications under which the driver runs use no new features. For example, IBM Data Server Driver for JDBC and SQLJ type 4 connectivity from the IBM Data Server Driver for JDBC and SQLJ version 2.x, which is shipped with DB2 for z/OS® Version 8, to a DB2 for z/OS Version 9.1 database is supported, if the applications under which the driver runs contain no DB2 for z/OS Version 9.1 features.
IBM Data Server Driver for JDBC and SQLJ type 4 connectivity to IBM Informix® is supported only for IBM Informix Version 11 and later.
In general, IBM Data Server Driver for JDBC and SQLJ type 2 connectivity is intended for connections to the local database system, using the driver version that is shipped with that database version. For example, version 3.6x of the IBM Data Server Driver for JDBC and SQLJ is shipped with DB2 for Linux, UNIX, and Windows Version 9.5 and Version 9.7, and DB2 for z/OS Version 8 and later.
However, for IBM Data Server Driver for JDBC and SQLJ type 2 connectivity to a local DB2 for Linux, UNIX, and Windows database, the database version can be one version earlier or one version later than the DB2 for Linux, UNIX, and Windows version with which the driver was shipped. For IBM Data Server Driver for JDBC and SQLJ type 2 connectivity to a local DB2 for z/OS subsystem, the subsystem version can be one version later than the DB2 for z/OS version with which the driver was shipped.
If the database version to which your applications are connecting is later than the database version with which the driver was shipped, the applications cannot use features of the later database version.
