Because each WebLogic Server domain can run concurrent, multiple instances of WebLogic Server, WebLogic logging services collect messages that are generated on multiple server instances into a single, domain-wide message log. You can use this domain-wide message log to see the overall status of the domain.
Use this page to configure the message log for this WebLogic Server domain.
By default, only the log messages of a
WARNING or higher
severity are forwarded from the local servers to the domain log. To change
the default, you must create a domain log filter.
|Log file name||
The name of the file that stores current log messages. Usually
it is a computed value based on the name of the parent of this
MBean. For example, for a server log, it is
However, if the name of the parent cannot be obtained, the file
To include a time and date stamp in the file name when the log
file is rotated, add
For example, if the file name is defined to be
When the log file is rotated, the rotated file name contains the
date stamp. For example, if the log file is rotated on 2 April,
2003 at 10:05 AM, the log file that contains the old messages will
If you do not include a time and date stamp, the rotated log
files are numbered in order of creation. For example,
Criteria for moving old log messages to a separate file.
After the server renames a file, subsequent messages accumulate
in a new file with the name that you specified in
|Rotation file size||
The size (1 - 65535 kilobytes) that triggers the server to move
log messages to a separate file. After the log file reaches the
specified minimum size, the next time the server checks the file
size, it will rename the current log file as
|Begin rotation time||
Determines the start time (hour and minute) for a time-based rotation sequence.
At the time that this value specifies, the server renames the current log file. Thereafter, the server renames the log file at an interval that you specify in File Time Span.
If the specified time has already past, then the server starts its file rotation immediately.
Use the following format:
The interval (in hours) at which the server saves old log
messages to another file. (Requires that you specify a file
rotation type of
|Limit number of retained files||
Indicates whether to limit the number of log files that this
server instance creates to store old messages. (Requires that you
specify a file rotation type of
After the server reaches this limit, it deletes the oldest log file and creates a new log file with the latest suffix.
If you do not enable this option, the server creates new files indefinitely and you must clean up these files as you require.
|Files to retain||
The maximum number of log files that the server creates when it rotates the log. This number does not include the file that the server uses to store current messages. (Requires that you enable Number of Files Limited.)
|Log file rotation directory||
The directory where the rotated log files will be stored. By default the rotated files are stored in the same directory where the log file is stored.
|Rotate log file on startup||
Specifies whether a server rotates its log file during its startup cycle.
Specifies whether the server logging is based on a Log4j implementation. By default, WebLogic logging uses an implementation based on the Java Logging APIs which are part of the JDK.
Applications that use the WebLogic Message Catalog framework or the NonCatalogLogger will not be affected by the underlying Logging implementation.
