Using your personal ad hoc list of logs offers a private alternative to using sessions.
There might be occasions when you want to browse logs without registering a session. Simply add logs
to your personal ad hoc list, and then select them for browsing.
About this task
This task can be summarized in three steps:
- On the Transaction Analysis Workbench Primary
Option Menu, select option 4
.
- Enter the location of a log. For example, the data set name of a dumped SMF file.
- Enter S next to the log to browse its entire
contents, or W to browse a time slice.
The following procedure expands on this summary, with details for different logs.
Procedure
- On the Transaction Analysis Workbench Primary
Option Menu, select
option 4
.
Your personal ad hoc list of logs is displayed.
-
In the Log File column, enter the data set names or the log stream names
of one or more logs that you want to browse.
- To specify a fully qualified data set name, enclose the name in single quotes. For
example:
'MVS1.SMF.MAN1.DUMP'
- To specify a log stream, prefix the log stream name with the log stream type, followed by a colon. For
example:
OPERLOG:SYSPLEX.OPERLOG
-
Depending on the type of log, you might also need to enter values in the following
columns:
- Rel
- (IMS log files only.) Overrides, for this log only, the
default IMS release specified in the IMS
Release field at the top of the panel.
You need to specify the IMS release because the format of IMS log
records varies between releases. If you specify an incorrect release, Transaction Analysis Workbench might incorrectly interpret the log records.
- Filter
- (Optional, for any log.) Specifies a filter that you want to use when processing this log:
- The name of a filter that is stored in the control repository
- A log type
- A log code
- A log type and code separated by a colon (:), such as IMS:01 or
DTR:3
- Zone
- (Optional, for any log.) Overrides, for this log only, the default time zone specified in the
Zone field at the top of the panel.
- UNIT and VOLSER
- (Uncataloged data sets only.) The device type (UNIT) and volume serial
number of the data set. If you specify VOLSER, you must also specify
UNIT.
To scroll hidden columns into view, press the Left function key (F10) or the Right function key (F11).
-
Decide whether you want to browse entire logs or a time slice: a specific time
period across one or more logs.
- To browse entire logs, type S next
to one or more logs, and then press Enter.
- To browse a time slice:
- Type W next to one or more logs, and then press
Enter.
The Investigate panel is displayed, listing the selected
logs.
- Specify the start and duration of the time slice that you want to browse, and then press Enter.
To set the time slice to match the start and duration of a particular log, enter T next to the log.
The Coverage
column displays information about how much of the time slice, if any, each log covers.
- Select the logs that you want to browse:
- To select all logs, enter S on the first line
under the slash (/) column heading.
- To select one or more logs, type S next to each
log, and then press Enter.
Time slicing uses a sampling method that favors speed over accuracy to locate log records in
large files. The sampling method sometimes includes records that are just outside the specified time
slice. When you specify a time slice, the log browser scrolls to the first log record in the time
slice. If you press the Backward function key (F7), you might see records that
are outside the specified time slice, but which have been included by the sampling method.
The
Duration
column displays the length of time that each log covers. If the Duration
column is not visible, press the Right function key (F11) to scroll the column
into view.
Results
The log browser displays the records in the selected logs.
