[Contents][Glossary][Index][Back][Next]

6.2.2 Available operations in the Multinode facility

The following operations can be performed when using the multi-node facility in a cluster system or parallel-processing system configuration. For details on commands, see the manual OpenTP1 Operation. For details on functions, see the OpenTP1 Programming Guide.

Organization of this subsection
(1) Starting and terminating OpenTP1 instances in a cluster system or parallel-processing system
(2) Collecting status of OpenTP1 nodes
(3) Collecting status of user servers in OpenTP1 nodes
(4) Collecting configuration information of the multinode area

(1) Starting and terminating OpenTP1 instances in a cluster system or parallel-processing system

You can enter commands from one OpenTP1 node to start or terminate OpenTP1 instances in a multinode subarea. Use the dcmstart command to start OpenTP1 instances in a multinode subarea, and the dcmstop command to terminate.

(2) Collecting status of OpenTP1 nodes

From one OpenTP1 node you can use the dcndls command to monitor the status of OpenTP1 nodes in the multinode area. The status of OpenTP1 nodes can be received also by issuing the dc_adm_get_nd_status_xxx() functions from a UAP.

(3) Collecting status of user servers in OpenTP1 nodes

You can receive the status of user servers in OpenTP1 nodes from one node by issuing the dc_adm_get_sv_status_xxx() functions from a UAP.

(4) Collecting configuration information of the multinode area

You can receive information about the system configuration (e.g., all OpenTP1 node identifiers in the multinode area or specified multinode subareas) by issuing the dc_adm_get_nodeconf_xxx() functions or the dc_adm_get_node_id_xxx() functions from a UAP.
