PRODDMF parameter group

Specifies the catalog name for META data requests for ADABAS tables.

Specifies the catalog name for META data requests for SQL/IMS tables.

Specifies the catalog name for META data requests for VSAM tables.

Specifies the catalog name for META data requests for VSAMCICS tables.

When set to YES, causes all display numeric fields defined in a data map to be converted to packed decimal before they are returned to the client.

Specifies the number of additional 4 KB pages to be allocated for DMF linear data set caching when the cache must be expanded.

Displays the address of the first actual DIV window, which is also the first logical window address.

Displays the count of 4 KB pages currently in the LDS object, but not yet in-use for caching. These pages are available immediately for use without expanding the overall LDS object size.

Specifies the number of 4 KB pages to be allocated in the DMF linear data set cache the first time it is accessed/formatted. The parameter is not used during restarts when the SxxMAPL linear data set has already been formatted. If not specified, 256 pages (1 MB) of cache space are initially formatted.

Displays count of internal “OPDL” blocks when the DMF Data-in-virtual caching facility is in use, zero, otherwise. Each time the DIV object is expanded dynamically by allocating a new extent of pages, an OPDL block is created at the front of that extent. Each OPDL manages free space and start-up time relocation for all of the 4 KB pages in the extent.

Displays the total 4 KB pages currently allocated in the LDS object. Set this parameter to zero if the DMF caching facility is not in use.

Displays the server’s current DMF DIV support level revision number. DMF DIV cache is checked during product restart for compatibility with the server’s current support level. If needed, the DMF cache is discarded and automatically reformatted at the new support level.

Displays the count of actual Data-in-virtual windows currently mapped when the DMF DIV caching facility is in use.

Controls the writing of SMF records for DMF maps that have been referenced since the startup of this Data Virtualization instance. It records the map details with non-zero usage counts.DMF Maps supports the following MAP types: ADABAS, SEQUENTIAL, VSAM, NATURAL, DB2, JGATE/DRDA, IMS, SQL VIEWS, and BROKER, both in the default schema (DVSQL) and any user-defined schema on the server.

Controls the writing of SMF records for DMF maps that have not been referenced since the startup of this Data Virtualization instance. It records the map details with a usage count of 0.DMF Maps supports the following MAP types: ADABAS, SEQUEDMFMAPUSAGEZERONTIAL, VSAM, NATURAL, DB2, JGATE/DRDA, IMS, SQL VIEWS, and BROKER, both in the default schema (DVSQL) and any user-defined schema on the server.

Controls whether or not virtual tables that are not defined in a schema should be added to 64-bit memory.

Specifying YES will cause VSAM, SEQ, IMS VIEW, and DRDA maps that are not defined to a schema to be added to 64-bit storage, other map types are not affected.

Displays the count of the DMF OPDW blocks currently allocated and in use.

This count is zero if DMF DIV caching is not enabled and in use, because free storage is returned to the system.

Allows the generation of unique PDS member names for imported maps across multiple Data Virtualization subsystems. This parameter, when set to a value other than NONE, causes an ENQ to be issued for the member name generated by the DMF import facility. Any 8-byte value can be entered here and is used as the QNAME for the ENQ. Use the same value across multiple instances of Data Virtualization to create “GROUPS” of subsystems for which you want to have unique member names.

When set to YES, causes the QUALIFIER/x_CAT field to be populated with the user-entered value for each table type as defined by parameters CATxxxx.
