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.
