Oper<strong>and</strong>s<br />

TRSOURCE ID (Definition Oper<strong>and</strong>s)<br />

You do not need to specify all of the definition oper<strong>and</strong>s on each invocation of the<br />

TRSOURCE comm<strong>and</strong>; you can build the definition piecemeal on a number of<br />

TRSOURCE comm<strong>and</strong>s. Note, however, that the TYPE oper<strong>and</strong> <strong>and</strong> certain TYPE<br />

parameters must be associated with a trace ID before that trace can be enabled.<br />

traceid<br />

identifies the trace; it is a user-defined, alphanumeric, 1- to 8-character string.<br />

You can specify traceid as a target on the ENABLE, DISABLE, <strong>and</strong> DROP<br />

oper<strong>and</strong>s to activate, deactivate, or delete a particular trace; you can also use<br />

traceid as a target for the TRSAVE comm<strong>and</strong>, which can alter the recording<br />

options for a trace.<br />

Used with the SET oper<strong>and</strong>, trace IDs can be grouped to form trace sets. A<br />

traceid cannot be a member of more than one trace set at a time.<br />

The trace ID also serves as the default name of the system trace file for the<br />

trace data. The oper<strong>and</strong> trace IDs cannot duplicate any of the following<br />

TRSOURCE keywords or any accepted abbreviation of these keywords: ID,<br />

SET, TYPE, ENABLE, DISABLE, DROP, DISPLAY, <strong>and</strong> ALL.<br />

SET traceset<br />

SET NULL<br />

is a user-defined, alphanumeric, 1- to 8-character string; it identifies the trace<br />

set that includes the specified trace ID. Creating trace sets lets you group<br />

individual traces that are functionally or logically related. You can then specify<br />

traceset as the target of the ENABLE, DISABLE, <strong>and</strong> DROP oper<strong>and</strong>s to<br />

activate, deactivate, or delete all of the trace IDs in traceset.<br />

A trace set can contain trace IDs of more than one type. A trace set of NULL<br />

indicates that the trace ID is not a member of any specific set. Set operations<br />

cannot be performed on the NULL set.<br />

A trace ID cannot be made a member of a set while it is enabled. Trace sets<br />

cannot duplicate any of the following TRSOURCE keywords or any accepted<br />

abbreviation of these keywords: ID, SET, TYPE, ENABLE, DISABLE, DROP,<br />

DISPLAY, <strong>and</strong> ALL.<br />

TYPE IO<br />

TYPE GT<br />

TYPE DATA<br />

specifies a system-defined trace type. The trace type determines which<br />

parameters are allowed <strong>and</strong> which are required for trace ID. The TYPE oper<strong>and</strong><br />

need only be specified once for a given trace ID but must be specified before or<br />

at the same time as any type parameter for that trace ID.<br />

Different trace IDs of the same trace type can be placed in the same or<br />

different trace sets. Trace types cannot be used as targets of the ENABLE,<br />

DISABLE, <strong>and</strong> DROP oper<strong>and</strong>s. Grouping of trace IDs is done with the SET<br />

oper<strong>and</strong>, not the TYPE oper<strong>and</strong>.<br />

type parameters<br />

The parameters <strong>and</strong> descriptions for the respective trace types are documented<br />

in the following sections:<br />

v “The I/O Trace”<br />

v “The GT Trace”<br />

v “The Data Trace”.<br />
