JMX Connection Handler

The JMX Connection Handler is used to interact with clients using the Java Management Extensions (JMX) protocol.

Parent

The JMX Connection Handler object inherits from Connection Handler.

Dependencies

JMX Connection Handlers depend on the following objects:

Basic Properties

allowed-client

SynopsisA set of clients who will be allowed to establish connections to this Connection Handler.
DescriptionValid values include a host name, a fully qualified domain name, a domain name, an IP address, or a subnetwork with subnetwork mask. Specifying a value for this property in a connection handler will override any value set in the global configuration.
Default Value

All clients with addresses that do not match an address on the deny list are allowed. If there is no deny list, then all clients are allowed.

Allowed Values

An IP address mask.

Multi-valued

Yes

Required

No

Admin Action Required

None

Changes to this property take effect immediately and do not interfere with established connections.

Advanced

No

Read-Only

No

denied-client

SynopsisA set of clients who are not allowed to establish connections to this Connection Handler.
DescriptionValid values include a host name, a fully qualified domain name, a domain name, an IP address, or a subnetwork with subnetwork mask. If both allowed and denied client masks are defined and a client connection matches one or more masks in both lists, then the connection is denied. If only a denied list is specified, then any client not matching a mask in that list is allowed. Specifying a value for this property in a connection handler will override any value set in the global configuration.
Default Value

If an allow list is specified, then only clients with addresses on the allow list are allowed. Otherwise, all clients are allowed.

Allowed Values

An IP address mask.

key-manager-provider

SynopsisSpecifies the name of the key manager that should be used with this JMX Connection Handler .
Default Value

None

Allowed Values

The name of an existing Key Manager Provider .

The referenced key manager provider must be enabled when the JMX Connection Handler is enabled and configured to use SSL.

Multi-valued

No

Required

No

Admin Action Required

None

Changes to this property take effect immediately, but only for subsequent attempts to access the key manager provider for associated client connections.

listen-address

SynopsisSpecifies the address on which this JMX Connection Handler should listen for connections from JMX clients.
DescriptionIf no value is provided, then the JMX Connection Handler listens on all interfaces.
Default Value

0.0.0.0

Allowed Values

A hostname or an IP address.

Default Value

None

Allowed Values

restricted-client

SynopsisA set of clients who will be limited to the maximum number of connections specified by the "restricted-client-connection-limit" property.
DescriptionValid values include a host name, a fully qualified domain name, a domain name, an IP address, or a subnetwork with subnetwork mask. Specifying a value for this property in a connection handler will override any value set in the global configuration.
Default Value

No restrictions are imposed on the number of connections a client can open.

Allowed Values

An IP address mask.

restricted-client-connection-limit

SynopsisSpecifies the maximum number of connections a restricted client can open at the same time to this Connection Handler.
DescriptionOnce Directory Server accepts the specified number of connections from a client specified in restricted-client, any additional connection will be rejected. The number of connections is maintained by IP address. Specifying a value for this property in a connection handler will override any value set in the global configuration.
Default Value

100

Allowed Values

An integer.

Lower limit: 0.

rmi-port

SynopsisSpecifies the port number on which the JMX RMI service will listen for connections from clients. A value of 0 indicates the service to choose a port of its own.
DescriptionIf the value provided is different than 0, the value will be used as the RMI port. Otherwise, the RMI service will choose a port of its own.
Default Value

0

Allowed Values

An integer.

Lower limit: 0.

ssl-cert-nickname

SynopsisSpecifies the nicknames (also called the aliases) of the keys or key pairs that the JMX Connection Handler should use when performing SSL communication.
DescriptionThe property can be used multiple times (referencing different nicknames) when server certificates with different public key algorithms are used in parallel (for example, RSA, DSA, and ECC-based algorithms). When a nickname refers to an asymmetric (public/private) key pair, the nickname for the public key certificate and associated private key entry must match exactly. A single nickname is used to retrieve both the public key and the private key. This is only applicable when the JMX Connection Handler is configured to use SSL.
Default Value

Let the server decide.

Allowed Values

A string.
