Description
The MESSAGE_LEVEL option specifies the level of messages to write.
It also specifies, optionally, whether or not to write a date and time stamp with each message.
Usage
Method | Syntax | IBM i | UNIX | Windows | z/OS |
Configuration File Keyword | message_level level[,time] | | | | |
Values
level indicates either of the following level of messages:
Default is info.
time specifies either of the following:
- time
Include a time and date stamp on each message. - notime
Do not include a time and date stamp on each message.
Default is time.
Trace Files
IBM i | Trace file name is *CURLIB/UNVTRCUDMS(Txxxyyyyyy) where: - xxx = first three digits of the process ID, in hexadecimal, assigned to this instance of the Server by IBM i.
- yyyyyy = last six digits of the component ID, in hexadecimal, assigned to this instance of the Server by the Broker.
These values are used to generate a unique identifier for each invocation of the UDMSRV program. The default library for TRACE is the current library (*CURLIB) of the UBROKER process, not the user process. The UBROKER current library is the temporary library designated during the Universal Agent installation process; by default, the UBROKER current library is UNVTMP510.

UNIX | Trace file name is udmsrv-N-S.trc where: - N = Component ID assigned to this instance of the Server.
- S = Sequence number.
The trace file is created in the trace directory, as specified by the TRACE_DIRECTORY option (default is /var/opt/universal/trace).

z/OS | There are two possible destinations of the trace data: - If ddname UNVTRMDL is defined in the UBROKER started task procedure, a sequential data set is created using the data set allocated to UNVTRMDL as a model. The dynamically allocated trace data set name is #HLQ.UDM.Dyymmdd.Thhmmss.Cnnnnnnn where:
- #HLQ* is the data set name allocated on the UNVTRMDL ddname
- yymmdd is the year, month, day
- hhmmss is the hour, minute, second the data set was allocated
- nnnnnnn is the last seven digits of the Server's component ID in hexadecimal format
- If ddname UNVTRMDL is not defined in the UBROKER started task procedure, member name Dnnnnnns is created in the PDS or PDS/E allocated to the UNVTRACE ddname, where, nnnnnn is the last six digits of the Server's component ID in hexadecimal format, and s is the component ID's sequence number (from 0 - F). Each time a server is restarted, its sequence number is incremented. If a server is restarted more than 15 times, tracing is disabled.
Depending on the error condition being diagnosed, it is possible that the member name of the UNVTRACE PDS or PDS/E is not created. If this occurs, the UNVTRMDL ddname must be used to create a sequential data set name. The records written to PDS and PDS/E members cannot be wrapped, so the TRACE_FILE_LINES limit has no effect on the maximum number of trace records written to the member.
