You can specify the location and settings for the system
log file in the Warehouse Administration Console.
You can also then use the Warehouse Administration Console to
view the system log files.
Before you begin
Log
in to the Warehouse
Administration Console.
For example, from a Web browser, type:
http://host_name:9080/ibm/warehouse.
Tip: If port number 9080 is already taken, you can find the
default port number in the portdef.props file
in the following location: WebSphere\AppServer\profiles\AppSrv01\properties.
The default port number for the Warehouse Administration Console is
specified by the WC_defaulthost property.
Procedure
To
set up the system logging service:
- Navigate to and select System Logging Service.
The Configure the System Logging Service window
opens.
- Specify a directory and a file name for the system log
file. You can use or modify the default log file (DS_System.log)
and path.
- Specify the amount of detail that you want in the log by
choosing a logging level:
| Logging level |
Description |
|---|
| Error |
Runtime errors of considerable importance |
| Warning |
Runtime events that are potential problems |
| Information |
Runtime events of interest |
| Debug |
Detailed information for debugging |
| Trace |
Highly detailed information for debugging (uses a lot of
system resources) |
Tip: The logging level that you select includes
all higher-severity messages. For example, if you specify Information as
your logging level, the system will write Information, Warning,
and Error messages to the system log. If you
specify Error, the system logging service will
log only error messages.
- Enable a rolling file if you want
the system logger to write to a rotating set of system log files rather
than to write to a single file. If you specify a rolling file, you
can also specify the size of the log and the number of files to use.
Note: Log files that do not yet exist are not listed on the
Manage
Logs page. For example, if you specify a rolling log of
three files, the system creates the first file and lists that first
file on the
Manage Logs page. When that file
reaches the length limit, the system creates the second file and lists
the first file and the second file on the
Manage Logs page.
And so on.
Also, if you change the location of a log file and then
restart the computer, the system lists only the active version of
the file that is in the new location. To see the version of the file
that is in the old location, you must open it from the directory in
which it is stored.
What to do next
You
can view the system log files in the Warehouse
Administration Console from
the
Manage Logs page. You can specify the number
of rows that you want to view from the file (the default view is the
last 200 rows).
