Specifying transaction and terminal-related trace options
In CETR you can control tracing for particular CICS® tasks by specifying the transaction
ID used to start the task, or the ID for the terminal from which the
task is to be run. You can set standard or special tracing for the
tasks, or suppress tracing for a task. You can also enable z/OS® Communications Server exit
tracing and ZCP trace for specific terminal IDs or netnames.
Procedure
To trace a single transaction using special tracing, perform
the following steps:
Enter CETR and set the master
system trace flag to OFF.
This setting turns standard
tracing off.
Press PF4 to select the levels of tracing for the required
components under the Special heading.
Return to the main CETR display and press PF5.
You get the following display, with the values of your
own system in each of the fields:
Note: VTAM® is now z/OS Communications Server.
Specify the transaction ID that you want to trace and
a transaction status of SPECIAL.
Setting special tracing for a particular transaction means
that special flags for each component are used to decide whether a
particular trace entry is to be made at any given point in the process
of the task.
To trace the tasks associated with a particular terminal,
perform the following steps:
Set the standard component trace flags to level 1 only.
Set the special component trace flags to level 1 and
level 2.
Set the trace for the terminal to special.
In this way, all tasks run from the specified terminal
have level 1 and level 2 tracing. All other tasks have level 1 tracing
only.
To set z/OS Communications
Server exit tracing in an AOR, enter the applid of the TOR as Netname
and enter ON for the Terminal z/OS Communications
Server Exit Trace.
If you want to trace the bind flows for an autoinstalled terminal
in a CICS region where dynamic
LU alias is in operation, the NETNAME you specify must be the real
network name. If you use the real network name and there is more
than one network using that name, the z/OS Communications
Server exit tracing is activated for each occurrence of the network
name.
If you want to trace an autoinstalled terminal when you know
the LU alias, specify the LUALIAS name.
