(ZOS) z/OS location service daemon settings

In a cell, one location service daemon definition exists for each sysplex node group. A location service daemon process runs on each system that has a node in a sysplex node group in that cell. When a client makes a remote call to an enterprise bean, a location service daemon determines which server or servers are eligible to process the request, and routes the request to the selected server. An example of a system is the z/OS operating system on a logical partition (LPAR).

Changes made to these settings apply to the location service daemon in a sysplex node group.

This administrative console page is only visible if the node group contains z/OS nodes. From the admin console, click...

        System administration > Node groups > sysplex_node_group > z/OS location service daemon.


Job name

The job name of the location service daemon. This name can be from one to eight characters. Use alphanumeric or the national language characters of @#$.

Information Value
Data type String
Default None


Start command

Command string that servers use to automatically start the location service daemon.

Information Value
Data type String
Format START location service daemon JCL procedure name

The procedure name is defined at the node level during customization. We can change the procedure name on the WebSphere Variables administrative console pages by going to Environment > WebSphere variables.

Example START BBO6DMN
Default ${NODE_DAEMON_START_COMMAND}

NODE_DAEMON_START_COMMAND is the configuration variable name whose value we can change on the WebSphere Variables administrative console pages.


Listen IP name

IP address on which the location service daemon listens. The Listen IP name must be either a dotted decimal IP address or an asterisk (*). The asterisk means that the location service daemon listens on all available IP addresses.

Information Value
Data type String
Default asterisk (*)


Daemon IP name

IP name that clients use to access enterprise beans and Common Object Request Broker Architecture (CORBA) components on servers that belong to the sysplex node group that this location service daemon serves.

The daemon IP name must be a DNS name and not a dotted-decimal IP address. The value must contain more than one qualifier such as "foo.com" and not a single qualifier, such as "foo."

Information Value
Data type String
Default None


Port

Port on which the location service daemon listens for Remote Method Invocation and Internet Inter-ORB (RMI/IIOP) requests.

Because the system reserves port numbers less than 1024 for Transmission Control Protocol/Internet Protocol (TCP/IP) applications, the recommendation is to use port numbers greater than 1023. However, the port range starts at 1.

Information Value
Data type Integer
Default None
Range 1 to 65535


SSL port

Port on which the location service daemon listens for encrypted Remote Method Invocation and Internet Inter-ORB (RMI/IIOP) requests.

Because the system reserves port numbers less than 1024 for Transmission Control Protocol/Internet Protocol (TCP/IP) applications, the recommendation is to use port numbers greater than 1023. However, the port range starts at 0. A value of 0 disables the SSL port.

Information Value
Data type Integer
Default None
Range 0 to 65535


SSL settings

Predefined list of Secure Sockets Layer settings for connections.

These settings are System SSL repertoires that we configured on the SSL repertoire panel. Select one repertoire from the list.
