PRPACE

Specifies the window size (in RUs) for pacing done between the primary logical unit and the boundary VTAM or NCP node. Using PRPACE substantially improves performance.

1 to 63

Specifies the pacing window size.

Default: The PRPACE 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 PRPACE value of 7 is recommended.
• PRPACE is equivalent to the VTAM VPACING operand.
