This section describes the MBeans that are available on the JMX Manager node.

The JMX Manager node includes all local beans listed under [Managed Node MBeans](list_of_mbeans_full.html#topic_48194A5BDF3F40F68E95A114DD702413) and the following beans that are available only on the JMX Manager node:

Represents the <%=vars.product_name%> Management layer for the hosting member. Controls the scope of management. This MBean provides `start` and `stop` methods to turn a managed node into a JMX Manager node or to stop a node from being a JMX Manager. For potential managers (`jmx-manager=true` and `jmx-manager-start=false`), this MBean is created when a Locator requests it.

**Note:**
You must configure the node to allow it to become a JMX Manager. See [Configuring a JMX Manager](jmx_manager_operations.html#topic_263072624B8D4CDBAD18B82E07AA44B6) for configuration information.

System-wide aggregate MBean that provides a high-level view of the entire distributed system including all members (cache servers, peers, locators) and their caches. At any given point of time, it can provide a snapshot of the complete distributed system and its operations.

The DistributedSystemMXBean provides APIs for performing distributed system-wide operations such as backing up all members, shutting down all members or showing various distributed system metrics.

You can attach a standard JMX NotificationListener to this MBean to listen for notifications throughout the distributed system. See [<%=vars.product_name%> JMX MBean Notifications](mbean_notifications.html) for more information.

This MBean also provides some MBean model navigation APIS. These APIs should be used to navigate through all the MBeans exposed by a <%=vars.product_name%> System.

System-wide aggregate MBean of a named region. It provides a high-level view of a region for all members hosting and/or using that region. For example, you can obtain a list of all members that are hosting the region. Some methods are only available for partitioned regions.

Represents a named instance of DistributedLockService . Any number of DistributedLockService can be created in a member.

A named instance of DistributedLockService defines a space for locking arbitrary names across the distributed system defined by a specified distribution manager. Any number of DistributedLockService instances can be created with different service names. For all processes in the distributed system that have created an instance of DistributedLockService with the same name, no more than one thread is permitted to own the lock on a given name in that instance at any point in time. Additionally, a thread can lock the entire service, preventing any other threads in the system from locking the service or any names in the service.

JMX Manager nodes will have managed node MBeans for themselves since they are also manageable entities in the distributed system.

## <a id="topic_48194A5BDF3F40F68E95A114DD702413__section_796A989549304BF7A536A33A913322A4" class="no-quick-link"></a>MemberMXBean

Member's local view of its connection and cache. It is the primary gateway to manage a particular member. It exposes member level attributes and statistics. Some operations like `createCacheServer()` and `createManager()` will help to create some <%=vars.product_name%> resources. Any JMX client can connect to the MBean server and start managing a <%=vars.product_name%> Member by using this MBean.

See [MemberMXBean Notifications](list_of_mbean_notifications.html#reference_czt_hq2_vj) for a list of notifications emitted by this MBean.
