VTAMPOOL macro

The VTAMPOOL macro, which is required for parallel session support, begins the definition of the LU 6.1 LTERM subpools.

You must define VTAMPOOL if any LU 6.1 node uses dynamic LTERM allocation. LTERMs, defined as LU 6.1 nodes, can be a fixed set or may be dynamically allocated depending on the composition of the VTAM® macro set. This macro initiates a hierarchy of macros, consisting of a VTAMPOOL statement and one or more subsequent SUBPOOL macros, each of which can optionally be followed by one or more NAME macros (if at least one SUBPOOL statement has an associated NAME statement). This macro set can occur anywhere in the VTAM macro set if it does not break into the TYPE–TERMINAL–NAME statement hierarchy. This macro has no operands.

Dynamic definition

You cannot dynamically define the LU 6.1 LTERM subpools.

Supported environments

The VTAMPOOL macro can be used in the DB/DC and DCCTL environments.

VTAMPOOL
All LU 6.1 SUBPOOLs can be defined under a single VTAMPOOL statement or under multiple VTAMPOOL statements. The only purpose of defining LU 6 SUBPOOLs using multiple VTAMPOOL statements is to aid in documenting the use of each LU 6 SUBPOOL.
