This MBean describes the configuration of the default file store. Each WebLogic Server instance has a default file store.
If you use the getMBeanInfo
operation in MBeanTypeServiceMBean, supply the following value as this MBean's fully qualified interface name:
weblogic.management.configuration.DefaultFileStoreMBean
No factory methods. Instances of this MBean are created automatically.
You can access this MBean from the following MBean attributes:
|
This section describes the following attributes:
The path name to the file system directory where the file store maintains its data files.
This attribute is not dynamically configurable.
Privileges | Read/Write |
Type | java.lang.String |
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 |
Redeploy or Restart required | Changes take effect after you redeploy the module or restart the server. |
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.

The disk write policy that determines how the file store writes data to disk.
This policy also affects the JMS file store's performance, scalability, and reliability. The valid policy options are:
Direct-Write
File store writes are written directly to disk. This policy is supported on Solaris, HP-UX, and Windows. On Windows systems, this option generally performs faster than the Cache-Flush option writes.
Disabled
Transactions are complete as soon as their writes are cached in memory, instead of waiting for the writes to successfully reach the disk. This policy is the fastest, but the least reliable (that is, transactionally safe). It can be more than 100 times faster than the other policies, but power outages or operating system failures can cause lost and/or duplicate messages.
Cache-Flush
Transactions cannot complete until all of their writes have been flushed down to disk. This policy is reliable and scales well as the number of simultaneous users increases.

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
|
javax.management.AttributeNotFoundException
javax.management.MBeanException
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
|
javax.management.AttributeNotFoundException
Restore the given property to its default value.
Operation Name | "unSet" |
Parameters | Object [] {
propertyName }
where:
|
Signature | String [] {
"java.lang.String" } |
Returns |
void
