Defining How Much of the RU to Store in the PIU Trace Table

The PIU trace facility automatically stores (or traces) 21 bytes of the RU in the PIU trace table. Use the ZNTRP command to increase or decrease how much of the RU is traced. You can define how much of the RU to trace for user data messages. You can also define how much of the RU to trace for SNA commands, data that flows on CDRM-CDRM sessions, and data that flows on CP-CP sessions.

To define how much of the RU to trace for user data messages, enter the ZNTRP command with the RUSZ parameter specified.

To define how much of the RU to trace for SNA commands, data that flows on CDRM-CDRM sessions, and data that flows on CP-CP sessions, enter the ZNTRP command with the CRUSZ parameter specified.

See TPF Operations for more information about the ZNTRP command.
