A QMF catalog is a set of database tables that contain resource limits, saved objects (queries, procedures, forms), reports, and other settings. QMF catalogs can only reside on database servers that host a DB2 database and are connected to using TCP/IP, SNA or CLI.
You specify that a database server will host a QMF catalog when you create the QMF catalog objects for a database server using the Packages Wizard.
Using the Catalog window, you must specify where the objects from the database server are stored in the QMF catalog. The objects can be stored in the QMF catalog server's main catalog or they can be stored in an extended catalog.
