CMEM Internal Trace

CMEM is supplied with the following internal trace facilities:

the ability to print an internal trace
the ability to print the contents of the CMEM internal data areas

Under normal circumstances, the debugging facilities are dormant. However, if required (that is, your BMC Customer Support has requested trace information), it is possible to activate the trace facilities as follows:

Perform either step 1 or 2 below.

Start a new CMEM monitor with the following operator command:
S CTMCMEM,TRACE=nn

The current CMEM monitor passes control to the new CMEM monitor and shuts down.
Issue the following operator command:
F CTMCMEM, TRACE=level

The required tracing level is supplied by BMC Customer Support. It can be any value from 000 to 255. (000 specifies no trace.)

Field

Description and Options

level

Trace levels to be activated or deactivated. The CMEM Internal Trace facility has 128 levels (that is, from 1 through 128). Any number of these levels can be on at a given time. Valid values:

x - Trace level to turn on

TRACE=3 turns on trace level 3.

‑x - Trace level to turn off

TRACE=‑3 turns off trace level 3.

(x:y) - Range of trace levels to turn on, where x is the first level in the range and y is the last level in the range.

TRACE=(1:10) turns on trace levels 1 through 10.

(‑x:‑y) - Range of trace levels to turn off, where x is the first level in the range and y is the last level in the range.

TRACE=(‑1:‑10) turns off trace levels 1 through 10.

(x,y,z,...) - Multiple trace levels to turn on.

TRACE=(3,5,29) turns on trace levels 3, 5 and 29.

(‑x,‑y,‑z,...) - Multiple trace levels to turn off.

TRACE=(‑3,‑5,‑29) turns off trace levels 3, 5 and 29.

SHOW - Shows the current status of all trace levels.

Avoid activating CMEM with the TRACE parameter on a regular basis, because if a JES problem occurs, CMEM may get hung up waiting for JES.

The trace information is printed to DD statements DATRACE and DADUMP of the CMEM procedure. If you are running a trace on the Subsystem Interface (SSI), start the General Trace Facility (GTF).
When you have finished your problem determination procedures, start a new CMEM using the either of following operator command:

S CTMCMEM

F CTMCMEM,TRACE=00
