Operand Explanations

The TRACE command to turn trace facilities on and off has the following operands:

ON

Activates a specified trace function.

OFF

Deactivates an indicated trace function.

ALL

Indicates that you want to begin or end a global trace for all physical and virtual terminals.

U=userid

Traces the physical and virtual terminals for the specified user ID.

MUT=termid

Specifies the terminal ID corresponding to the user you want this command to act on. Use this operand if the user ID you specify is signed on to multiple terminals.

T=termid

Specifies the VTAM network name (the APPL statement label) for a physical terminal to be traced.

P=prtrid

Specifies the VTAM network name (the APPL statement label) for a printer to be traced.

VT=vtermid

Specifies the VTAM network name (the APPL statement label) for a virtual terminal to be traced.

VP=vprtrid

Specifies the VTAM network name (the APPL statement label) for a virtual printer to be traced.

EVERY

Indicates that you want to trace modules, buffers, and VTAM control blocks. This is the default trace.

MOD

Indicates that you want to trace modules.

ACB

Indicates that you want the virtual terminal mask search process to be written to the log.

Important! If your site uses a large number of virtual terminals, an ACB trace can cause a U032 abend. The abend occurs as numerous trace messages accumulate while waiting to be written to the log.

BUF

Indicates that you want trace buffers for both physical and virtual terminals during send/receive processing. It also causes tracing of VTAM control blocks.

SYSID=tpxappl

Identifies a specific instance of CA TPX on which the command is to be executed. For details, see the Operand Explanations for the ACTIVATE command.
