Before you can create a PIUPRT report to view or print offline, you must write the PIU trace table to a real-time tape. See Using the Offline PIU Print (PIUPRT) Utility to Create a PIUPRT Report for more information about creating a PIUPRT report.
To write the PIU trace table to a real-time tape, do the following:
The PIU trace facility will automatically write each 4-KB block of the PIU trace table to the real-time tape when that 4-KB block becomes full. If the length of the queue to the real-time tape becomes too large, the PIU trace facility stops writing the PIU trace table to tape until the queue becomes smaller. The maximum tape queue length is defined in keypoint 2 (CTK2) using the PIUTAPEQ parameter in the SNAKEY macro. See TPF ACF/SNA Network Generation for more information about the SNAKEY macro.
When you are ready to create a PIUPRT report, stop writing the PIU trace table to the real-time tape. To stop writing the PIU trace table to the real-time tape, do the following:
See TPF Operations for more information about the ZNTRP command.
