Subtypes |
The following MBeans extend or implement this MBean type: |
This section describes the following attributes:
Gets the underlying log buffer size in kilobytes
Privileges | Read/Write |
Type | int |
Default Value | 8 |
Private property that disables caching in proxies.
Privileges | Read only |
Type | boolean |
Redeploy or Restart required | Changes take effect after you redeploy the module or restart the server. |
The date format pattern used for rendering dates in the log. The
DateFormatPattern string conforms to the specification of the
java.text.SimpleDateFormat
class.
Privileges | Read/Write |
Type | java.lang.String |
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.)
For more information, see:
Privileges | Read/Write |
Type | int |
Default Value | 7 |
Minimum value | 1 |
Maximum value | 99999 |
The size (1 - 65535 kilobytes) that triggers the server to move
log messages to a separate file. The default is 500 kilobytes.
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 SERVER_NAME.lognnnnn
and
create a new one to store subsequent messages. (Requires that you
specify a file rotation type of Size
.)
For more information, see:
Privileges | Read/Write |
Type | int |
Default Value | 500 |
Minimum value | 1 |
Maximum value | 65535 |
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
SERVER_NAME.log
.
However, if the name of the parent cannot be obtained, the file
name is weblogic.log
. If you specify a relative
pathname, it is interpreted as relative to the server's root
directory.
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
myserver_%yyyy%_%MM%_%dd%_%hh%_%mm%.log
, the log file
will be named myserver_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 for the first
time on 2 April, 2003 at 10:05 AM, the log file that contains the
old messages will be named
myserver_2003_04_02_10_05.log00001
.
If you do not include a time and date stamp, the rotated log
files are numbered in order of creation. For example,
myserver.log00007
.
Privileges | Read/Write |
Type | java.lang.String |
The interval (in hours) at which the server saves old log
messages to another file. (Requires that you specify a file
rotation type of TIME
.)
For more information, see:
Privileges | Read/Write |
Type | int |
Default Value | 24 |
Minimum value | 1 |
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.
Privileges | Read/Write |
Type | java.lang.String |
Returns the MBean info for this MBean.
Deprecated.
Privileges | Read only |
Type | javax.management.MBeanInfo |
Redeploy or Restart required | Changes take effect after you redeploy the module or restart the server. |
The user-specified name of this MBean instance.
This name is included as one of the key properties in the
MBean's javax.management.ObjectName
:
Name=user-specified-name
Privileges | Read/Write |
Type | java.lang.String |
Optional information that you can include to describe this configuration.
WebLogic Sever saves this note in the domain's configuration
file (config.xml
) as XML PCDATA. All left angle
brackets (<) are converted to the XML entity
<
. Carriage returns/line feeds are
preserved.
If you create or edit a note from the Administration Console, the Administration Console does not preserve carriage returns/line feeds.
Privileges | Read/Write |
Type | java.lang.String |
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 SIZE
or
TIME
.)
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.
For more information, see:
Privileges | Read/Write |
Type | boolean |
Default Value | true |
Returns the ObjectName under which this MBean is registered in the MBean server.
Deprecated.
Privileges | Read only |
Type | weblogic.management.WebLogicObjectName |
Redeploy or Restart required | Changes take effect after you redeploy the module or restart the server. |
Return the immediate parent for this MBean
Privileges | Read/Write |
Type |
Returns false if the MBean represented by this object has been unregistered.
Deprecated.
Privileges | Read only |
Type | boolean |
Redeploy or Restart required | Changes take effect after you redeploy the module or restart the server. |
Specifies whether a server rotates its log file during its startup cycle.
Privileges | Read/Write |
Type | boolean |
Default Value | true |
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.
Note that WebLogic Server sets a threshold size limit of 500 MB before it forces a hard rotation to prevent excessive log file growth.
Use the following format: H:mm
, where
H
is Hour in day (0-23).
mm
is the minute in hour
For more information, see:
Privileges | Read/Write |
Type | java.lang.String |
Default Value | 00:00 |
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 too large. Note that WebLogic Server sets a threshold size limit of 500 MB before it forces a hard rotation to prevent excessive log file growth.
SIZE
When the log file reaches the size that you specify in
FileMinSize
, the server renames the file as
SERVER_NAME.lognnnnn
.
TIME
At each time interval that you specify in TimeSpan
,
the server renames the file as
SERVER_NAME.lognnnnn
.
After the server renames a file, subsequent messages accumulate in a new file with the name that you specified as the log file name.
Privileges | Read/Write |
Type | java.lang.String |
Default Value | bySize |
Legal Values |
|
Secure value | byTime |
Returns the type of the MBean.
Privileges | Read only |
Type | java.lang.String |
Redeploy or Restart required | Changes take effect after you redeploy the module or restart the server. |
This section describes the following operations:
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.
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.
Operation Name | "freezeCurrentValue" |
Parameters | Object [] { attributeName }
where:
|
Signature | String [] {
"java.lang.String" } |
Returns |
void
|
Exceptions |
|
Returns true if the specified attribute has been set explicitly in this MBean instance.
Operation Name | "isSet" |
Parameters | Object [] { propertyName }
where:
|
Signature | String [] {
"java.lang.String" } |
Returns |
boolean
|
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.
Operation Name | "restoreDefaultValue" |
Parameters | Object [] { attributeName }
where:
|
Signature | String [] {
"java.lang.String" } |
Returns |
void
|
Exceptions |
|
Restore the given property to its default value.
Operation Name | "unSet" |
Parameters | Object [] { propertyName }
where:
|
Signature | String [] {
"java.lang.String" } |
Returns |
void
|
