PSPACE

Specifies the window size (in RUs) for pacing done between the secondary logical unit and the boundary VTAM or NCP node.

1 to 63

Specifies the pacing window size.

Default: The PSPACE value derived from the VTAM logmode table entry used by VTAM during initial session establishment and passed to CA XCOM Data Transport via the LOGON exit CINIT or SCIP exit bind RU.

Notes:

• A PSPACE value of 7 is recommended.
• The use of PSPACE can substantially improve performance.
• PSPACE is equivalent to the VTAM VPACING operand.
