LogFileLimitEnabled

Indicates whether the number of files that this WebLogic Server retains to store old messages should be limited. After the server reaches this limit, it overwrites the oldest file.

Indicates whether a server will limit the number of log files that it creates when it rotates the log. The limit is based on getLogFileCount.

Deprecated. 9.0.0.0 Use getWebServerLog().getNumberOfFilesLimited()

       
Privileges Read/Write
Typeboolean

LogFileName

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

The name of the file that stores the HTTP-request log. If the pathname is not absolute, the path is assumed to be relative to the server's root directory.

This value is relevant only if HTTP logging is enabled.

The current logfile is always the one whose name equals value of the this attribute. If you have enabled log file rotation, when the current file exceeds the size or time limit, it is renamed.

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

For example, if the file name is defined to be access_%yyyy%_%MM%_%dd%_%hh%_%mm%.log, the log file will be named access_yyyy_mm_dd_hh_mm.log.

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 be named access_2003_04_02_10_05.log.

If you do not include a time and date stamp, the rotated log files are numbered in order of creation. For example, access.log00007.

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 LogRotationPeriodMins.

Use the following format: MM-dd-yyyy-k:mm:ss where

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

MaxLogFileSizeKBytes

The maximum size (in kilobytes) of the HTTP log file. After the log file reaches this size, the server renames it as LogFileName.n. A value of 0 indicates that the log file can grow indefinitely. (This field is relevant only if you set Rotation Type to size.)

The size that triggers the server to move log messages to a separate file. After the log file reaches the specified size, the next time the server checks the file size, it will rename the current log file as FileName.n and create a new one to store subsequent messages.

Operations

This section describes the following operations:


addTarget

You can add a target to specify additional servers on which the deployment can be deployed. The targets must be either clusters or servers.

   
Operation Name"addTarget"
ParametersObject [] {  target }

where:

  • target is an object of type weblogic.management.configuration.TargetMBean that specifies:

    The feature to be added to the Target attribute

SignatureString [] { "weblogic.management.configuration.TargetMBean" }
Returns boolean
Exceptions
  • javax.management.InvalidAttributeValueException
  • weblogic.management.DistributedManagementException

freezeCurrentValue

If the specified attribute has not been set explicitly, and if the attribute has a default value, this operation forces the MBean to persist the default value.

Unless you use this operation, the default value is not saved and is subject to change if you update to a newer release of WebLogic Server. Invoking this operation isolates this MBean from the effects of such changes.

Note:

To insure that you are freezing the default value, invoke the restoreDefaultValue operation before you invoke this.

This operation has no effect if you invoke it on an attribute that does not provide a default value or on an attribute for which some other value has been set.

Deprecated. 9.0.0.0

   
Operation Name"freezeCurrentValue"
ParametersObject [] {  attributeName }

where:

  • attributeName is an object of type java.lang.String that specifies:

    attributeName

SignatureString [] { "java.lang.String" }
Returns void
Exceptions
  • javax.management.AttributeNotFoundException
  • javax.management.MBeanException

isSet

Returns true if the specified attribute has been set explicitly in this MBean instance.

   
Operation Name"isSet"
ParametersObject [] {  propertyName }

where:

  • propertyName is an object of type java.lang.String that specifies:

    property to check

SignatureString [] { "java.lang.String" }
Returns boolean

removeTarget

Removes the value of the addTarget attribute.

For more information, see:

   
Operation Name"removeTarget"
ParametersObject [] {  target }

where:

  • target is an object of type weblogic.management.configuration.TargetMBean that specifies:

    target

SignatureString [] { "weblogic.management.configuration.TargetMBean" }
Returns boolean
Exceptions
  • javax.management.InvalidAttributeValueException
  • weblogic.management.DistributedManagementException

restoreDefaultValue

If the specified attribute has a default value, this operation removes any value that has been set explicitly and causes the attribute to use the default value.

Default values are subject to change if you update to a newer release of WebLogic Server. To prevent the value from changing if you update to a newer release, invoke the freezeCurrentValue operation.

This operation has no effect if you invoke it on an attribute that does not provide a default value or on an attribute that is already using the default.

Deprecated. 9.0.0.0

   
Operation Name"restoreDefaultValue"
ParametersObject [] {  attributeName }

where:

  • attributeName is an object of type java.lang.String that specifies:
