You can use the Log Browse Utility (BBORBLOG) to view error
log contents for troubleshooting and tuning purposes.
About this task
You can use the Log Browse Utility (BBORBLOG) to view the
error log stream. If you need to look at the WebSphere® Application
Server for z/OS® error log stream, use ISPF option 6 to
enter the command:
Procedure
- Use ISPF option 6 to enter the proper command.
ex 'BBO.SBBOEXEC(BBORBLOG)' 'BBO.BOSSXXXX'
where
the log-stream name is BBO.BOSSXXXX
- The space allocation and the unit for the allocation are
contained within the REXX code. If you keep a large amount of trace
data, the allocation must be made larger.
- The WebSphere Application Server for z/OS provides
an ISPF REXX EXEC named BBORBLOG, that allows you to browse the error
log stream.
- Save the output.
When you use the BBORBLOG
browser, it creates a data set name, which depends on the TSO PROFILE
PREFIX value. If you invoke the TSO environment with a TSO PROFILE
PREFIX definition value, this value is used, in conjunction with the
log stream name, to form the output data set. For example, if you
issue the TSO PROFILE PREFIX(HARRY) command and the log stream name
is BBO.BOSSXXXX, the output data set is HARRY.BBO.BOSSXXXX.
If
you wish to save your browser output, you can use the outdsn parameter
to specify a name for the output data set before you save it. For
more information on this parameter, see the usage information on the
BBORBLOG log browse utility. The contents of the current view of the
log stream will remain until the stream reaches its retention date.
The next time you invoke the browser, however, the current view of
the log stream will be deleted because if it uses the same data set
name. If you use the outdsn parameter to specify
a unique output data set name the current view of the log stream is
not deleted. The previous data will exist in another record (not the
current view) until its retention date.
Results
Use the following information to determine viewing of the
error log:
- By default, the macro formats the error records to fit a 3270
display.
- Timestamps are in Greenwich Mean Time (GMT) unless changed by
setting the WebSphere Application Server variable ras_time_local
to 1.
- Message BBOJ0051I, which appears in the job output, can help
correlate error-log entries to the proper job output.
