This document provides trace information for the following components:
To switch on tracing
Set the attribute TRACE-LEVEL in the broker attribute file
for minimal trace output to "1"
for detailed trace output to "2"
for full trace output to "3"
Example:
TRACE-LEVEL=2
To switch off tracing
Set the attribute TRACE-LEVEL in the broker attribute file to 0:
TRACE-LEVEL=0
Or:
Omit the TRACE-LEVEL attribute.
It is not always convenient to run with
TRACE-LEVEL defined, especially when higher
trace levels are involved. Deferred tracing is triggered when a specific
condition occurs, such as an ACI response code or a broker subtask abend.
Such conditions cause the contents of the trace buffer to be written, showing trace
information leading up the specified event. If the specified event does not
occur, the Broker trace will contain only startup and shutdown information
(equivalent to TRACE-LEVEL=0).
Operating the trace in this mode requires the following additional attributes in the broker
section of the attribute file.
Values for TRBUFNUM and TRAP-ERROR are only examples.
| Attribute | Value | Description |
|---|---|---|
TRBUFNUM |
3 |
Specifies the deferred trace buffer size = 3 * 64 K. |
TRMODE |
WRAP |
Indicates trace is not written until an event occurs. |
TRAP-ERROR |
322 |
Assigns the event ACI response code 00780322 "PSI: UPDATE failed". |
The following methods are available to switch on or off the EntireX Broker trace dynamically. You do not need to restart the broker for the changes to take effect.
ETBCMD
Run command utility ETBCMD with option -c TRACE-ON or - c TRACE-OFF.
See ETBCMD.
Operator Command
Issue an operator command. See TRACE.
See also Deferred Tracing.
The following table describes the possible values for the broker stub trace:
| Trace Level | Description | |
|---|---|---|
| 0 | NONE |
No tracing. Switch tracing off. |
| 1 | STANDARD |
Traces initialization, errors, and all ACI request/reply strings. |
| 2 | ADVANCED |
Used primarily by system engineers, traces everything from level 1 and provides additional information, for example the Broker ACI control block, as well as information from the transports. |
| 3 | SUPPORT |
This is full tracing through the stub, including detailed traces of control blocks, message information, etc. |
Trace options can be supplied to broker stubs for NET communication as well TCP/SSL communication via SDF job control statements or JV job variables:
| Transport | SDF Job Control | JV Control | Output |
|---|---|---|---|
TCP/SSL |
/ETB-STUBLOG = '3' |
CREATE-JV ETB-STUBLOG |
<tsn>.ETB |
|
|
CREATE-JV EXA-LOG |
<tsn>.EXA |
Remember to switch off tracing to prevent trace files from filling up your disk.
Set the SDF job control option to '0' or delete it.
Set the JV job variable to '0' or delete it, for example
DELETE-JV ETB-STUBLOG
To switch on tracing for the RPC server
Set the parameter TRACELEVEL in S-element RPC-CONFIG in EXP103.JOBS.
To evaluate the RPC server return codes, see EntireX RPC Server Return Codes.
The Broker Security Server comes with a trace facility that can be used to track the IDs of users logging on to EntireX Broker. It also produces some diagnostic messages that are helpful for problem analysis. By default, no tracing is performed.
To switch on tracing for Broker Security Server
Set up an SDF variable in the server's job control.
TRACE='ON'
To switch off tracing for Broker Security Server
Set the following in the server's job control.
TRACE='OFF'
