Specifying the TSIDMAP Macro
The TSIDMAP macro is always required when specifying pools. It specifies:
• DTF names that must be uncontrolled (ignored by BIM-EPIC)
•
DTF names for which LUB allocation must be inhibited
• Programs for which LUB allocation must be inhibited (this affects every dataset the
program opens)
• The size of the work area to be used to map disk devices.
See Chapter 1 of the BIM-EPIC User Reference for an explanation of BIM-EPIC LUB
allocation.

nnn indicates the maximum number of unexpired extents to support on any controlled disk
volume in any defined pool. BIM-EPIC uses this number to reserve space in the VSE
Partition GETVIS area for the map table it uses to allocate disk datasets. If the map table
capacity is exceeded during allocation processing, BIM-EPIC cancels the job.
The number you specify should be at least 300. Generally, a map specification of 800 is
sufficient for large devices (for instance, FBA or 3380). However, because 255 extents per
file are supported, underallocated files that are allowed to fragment could easily fill an
inadequate map table capacity. So be generous! If you use more than one TSIDMAP macro
statement, specify this parameter only on the first one.
For ILIST, NLUBDTF, and NLUBPGM: You can specify up to 31 items per parameter. Use
multiple TSIDMAP statements if you want to specify more than 31 items. These parameters
are mutually exclusive. Use separate TSIDMAP macro statements to specify each one.
