File Name

The name of the file that stores current log messages. If the pathname is not absolute, the path is assumed to be relative to the root directory of the machine on which the server is running.

If the name does not include a path element, then pathname will be computed as follows:

• For a server log file, ./SERVER_NAME

• For a domain log file, ./

If neither file name nor pathname is specified, then the name is computed as follows:

• For a server log file, ./SERVER_NAME/SERVER_NAME.log

• For a domain log file, ./DOMAIN_NAME.log

To include a time or date stamp in the file name when the log file is rotated, add java.text.SimpleDateFormat variables. Surround each variable with percentage (%) characters.

For example, weblogic_%yyyy%_%MM%_%dd%_%hh%_%mm%.log

If you do not include a time and date stamp, the rotated log files are numbered in order of creation filenamennnnn, where filename is the name configured for the log file.

MBean: weblogic.management.
configuration.LogMBean

Attribute: FileName

Default: "weblogic.log"

Configurable: yes

Readable: yes

Writable: yes

Rotation Type

Criteria for moving old log messages to a separate file:

• NONE. Messages accumulate in a single file. You must erase the contents of the file when the size is unwieldy.

• SIZE. When the log file reaches the size that you specify in FileMinSize, the server renames the file.

• TIME. At each time interval that you specify in TimeSpan, the server renames the file.

After the server renames a file, subsequent messages accumulate in a new file with the name that you specified in FileName.

MBean: weblogic.management.
configuration.LogMBean

Attribute: RotationType

Default: "none"

Valid values:

• "bySize"

• "byTime"

• "none"

Configurable: yes

Dynamic: yes

Readable: yes

Writable: yes

File Min Size

The file 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 and create a new one to store subsequent messages.

MBean: weblogic.management.
configuration.LogMBean

Attribute: FileMinSize

Units: kilobytes

Minimum: 1

Maximum: 65535

Default: 500

Configurable: yes

Dynamic: yes

Readable: yes

Writable: yes

Rotation Time

Determines the start time 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 FileTimeSpan.

Use the following format: hh:mm, where hh is the hour in a 24-hour format and mm is the minute.

If the time that you specify has already past, then the server starts its file rotation immediately.

MBean: weblogic.management.
configuration.LogMBean

Attribute: RotationTime

Default: 00:00

Configurable: yes

Dynamic: yes

Readable: yes

Writable: yes

File Time Span

The interval (in hours) at which the server saves old log messages to another file. This value is relevant only if you use the time-based rotation type.

MBean: weblogic.management.
configuration.LogMBean

Attribute: FileTimeSpan

Units: hours

Minimum: 1

Default: 24

Configurable: yes

Dynamic: yes

Readable: yes

Writable: yes

Number Of Files Limited

Limits the number of files that a server creates to store old messages to the maximum number specified in FileCount. After the server reaches this limit, it overwrites the oldest file.

If you do not enable this option, the server creates new files indefinitely. You must clean up these files as you require.

This value is relevant only if you specify a file rotation type of SIZE or TIME.

MBean: weblogic.management.
configuration.LogMBean

Attribute: NumberOfFilesLimited

Default: false

Dynamic: yes

Readable: yes

Writable: yes

File Count

The maximum number of log files that the server creates when it rotates the log. Only valid if isNumberOfFilesLimited is true and setRotationType is either Size or Time.

MBean: weblogic.management.
configuration.LogMBean

Attribute: FileCount

Default: 7

Configurable: yes

Dynamic: yes

Readable: yes

Writable: yes
