SDSNLOADn

SDSNLOAD n = dsname
SDSNLOADn
Where n is a number in the range 1 to 6, this parameter specifies the names of the data sets that contain the external subsystem load modules required for IMS BMP processing, such as Db2 ®attachment and related external subsystem support.
When a FM/IMS function accesses the IMS™ subsystem in BMP mode for Edit, the specified APF-authorized data sets are allocated to the DFSESL DD statement as a concatenation with the RESLIBn data sets.
The SDSNLOADn parameters are optional. However, if you specify an SDSNLOAD parameter, you must also specify all preceding SDSNLOAD parameters.

For example, If you specify the SDSNLOAD3 parameter, you must also specify SDSNLOAD1 and SDSNLOAD2.

Default
If no SDSNLOADn parameters are specified on the FMN1POPI macro statement, FM/IMS uses the SDSNLOADn values specified on the FMN1POPD macro statement, if present. Otherwise, no SDSNLOAD data sets are allocated to the DFSESL DD statement.
