Declaring the dynamic PSBs
If you do not plan to use dynamic PSBs to access databases in BMP mode or dynamic resource definition for MODBLKS resources is enabled and you plan to use the IMS Data Definition utility to generate dynamic PSBs, declaring the dynamic PSBs is not required.
Otherwise, you must include in the system definition an APPLCTN macro statement for each dynamic PSB name used by FM/IMS functions when run in BMP mode.
The dynamic PSB names that FM/IMS uses are obtained by combining the 1- to 5-characters you specify in the DYNPRFX parameter with a three-digit number in the range 001 to the number specified in the DYNPRFN parameter.
APPLCTN PSB=FMN001,PGMTYPE=BATCH,DOPT
APPLCTN PSB=FMN002,PGMTYPE=BATCH,DOPT
APPLCTN PSB=FMN003,PGMTYPE=BATCH,DOPT
PGMTYPE=BATCH is required because the PSBs are for BMPs. The DOPT parameter specifies that it is a dynamic PSB, so
it is also required.
