A QMF Compatibility mode installation is similar to an installation of a previous level of QMF. QMF owner names are limited to 8 characters and QMF object names are limited to 18 characters. A QMF Compatibility mode installation can co-exist in the same server with previous releases of QMF.
A QMF Version 8.1 New Function mode installation allows for QMF owner and object names as long as the database allows (maximum of 128 characters in length). A QMF New Function mode installation cannot co-exist in the same server with a previous release of QMF. The following servers will accept a QMF New Function mode installation:
A QMF NFM requester can connect to a QMF Compatibility mode server as long as the DB2 QMF Version 8.1 packages were bound to the server and the requester. Both the requester and the server must have the same release level package.
Users may migrate from QMF Compatibility mode to QMF New Function mode at any time. A QMF New Function mode installation can be done by either migrating from a QMF Compatibility mode installation, or into a server that does not contain a previous release of QMF. To migrate from a previous release of QMF to QMF New Function mode, you must first migrate to QMF Compatibility mode, then migrate to QMF New Function mode.
