public interface ReplicatedStoreMBean

extends PersistentStoreMBean

Defines an instance of a Replicated Store.

A WebLogic Replicated Store is a high performance storage option for Exalogic hosted Weblogic Messaging Services and is an alternative to WebLogic Server's File and JDBC persistent storage options. Replicated stores depend on Exalogic replicated memory that is managed by a separately administered Daemon Cluster that must be started before a WebLogic Replicated Store can boot.

See Using the WebLogic Replicated Store in Administering WebLogic Server for Oracle Exalogic Elastic Cloud.

This feature should be used only in Oracle Exalogic Elastic Cloud environments.

Since:

12.1.3.0

getDirectory

String getDirectory()

Specifies the path of the Replicated Store Global Directory.

This must be the same directory that is used to store the Daemon Cluster rs_daemons.cfg configuration file and requires a specially tuned NFS mount. Oracle recommends using an absolute directory path on a shared NFS mount.

Returns:

The directory value

setDirectory

void setDirectory(String directory)
                  throws InvalidAttributeValueException

Sets the value of the Directory attribute. See getDirectory for more help.

Parameters:

directory - The new directory value

Throws:

InvalidAttributeValueException

See Also:

ReplicatedStoreMBean.getDirectory()

getLocalIndex

int getLocalIndex()

Specifies a local Daemon to attach to when a Daemon Cluster has multiple Daemons configured to run on the current node.

The local Daemon is chosen using the formula: ((localindex) modulo (number-of-local-daemons)). When 0, it always resolves to the first available Daemon entry in the rs_daemons.cfg file that has an address on the current node. The default value is 0.

This setting is not applicable to production environments. To ensure high availability, a Daemon Cluster in a production environment should have multiple nodes with one Daemon on each node.

Returns:

The LocalIndex value

setLocalIndex

void setLocalIndex(int localIndex)

Sets the value of the LocalIndex attribute. See getLocalIndex for more detailed help.

Parameters:

localIndex - The new LocalIndex value

Throws:

InvalidAttributeValueException

See Also:

ReplicatedStoreMBean.getLocalIndex()

getRegionSize

int getRegionSize()

The region size, in bytes.

Data is stored in one or more uniquely named Regions within a Daemon Cluster where each region is created with this size. Oracle recommends that regions sizes should be tuned to be a small fraction of the available local Daemon memory.

Returns:

The RegionSize value

setRegionSize

void setRegionSize(int regionSize)

Sets the value of the RegionSize attribute. See getRegionSize for more detailed help.

Parameters:

regionSize - The new RegionSize value

Throws:

InvalidAttributeValueException

See Also:

ReplicatedStoreMBean.getRegionSize()

getIoBufferSize

int getIoBufferSize()

The I/O buffer size, in bytes, automatically rounded down to the nearest power of 2.

• Controls the amount of WebLogic Server JVM off-heap (native) memory that is allocated for a replicated store.
• For the best runtime performance, Oracle recommends setting IOBufferSize so that it is larger than the largest write (multiple concurrent store requests may be combined into a single write).
• For the best boot recovery time performance of large stores, Oracle recommends setting IOBufferSize to at least 2 megabytes.

Returns:

The IoBufferSize value

setIoBufferSize

void setIoBufferSize(int ioBufferSize)

Sets the value of the IOBufferSize attribute. See getIoBufferSize for more information.

Parameters:

ioBufferSize - The new IOBufferSize value

Throws:

InvalidAttributeValueException

See Also:

ReplicatedStoreMBean.getIoBufferSize()
