NODE Statement Parameters

NODe nodename

Specifies the node name (SYSTEM ID) of the CA IDMS CV that is accessed from the DC/UCF system being defined.

Nodename is:

• A unique one- to eight-character alphanumeric value beginning with an alphabetic character.
• Matches the name of a system defined in the DC/UCF communications network.

When using a type of GROUP, the group name replaces the SYSTEM ID in the nodename parameter.

CCI

For DDS users only, specifies CAICCI, the Common Communications Interface component of the CA Integration Services layer, is used to access the named node.

CCI can be specified for resources residing on different CPUs.

CVNumber is cv-number

Specifies the communication method for the named node is a CA IDMS central version and identifies its central version number. The CVNUMBER IS parameter is used with SVC-type connections only.

Cv-number is an integer ranging from 0 to 255. The combination of cv-number and svc-number (described next) must uniquely identify the named node.

SVC svc-number

Specifies the SVC number of the CA IDMS CV receiving packets sent by the CA IDMS system currently being defined.

Svc-number is an integer ranging from 0 to 255.

BLOcksize blk-size Specifies the size of the packet used to pass data between nodes.

Blk-size is the blocksize of the data packet sent between CVs.

The default blk-size is 8192.

LOCal

Specifies the named node is the DC/UCF system being defined.

LOCAL is the default.

GROup

Specifies the named node is a DBGroup. This is the group name specified on the database name table DBGROUP statement.

DEFault NODe

Specifies the node to use if access to the DBGroup fails (i.e., there are no active CVs available to service a DBGroup request).

Nodename

Specifies a node name to use if access to the DBGroup fails. This node must be defined with an access type of CCI, CVNUMBER, or VTAM.

LOCal

Specifies the node to use is local, which is the current system. The database session is processed by the system being defined.

NULl

Specifies there is no default node. If a database session is routed to the named DBGroup, and there are no CVs available to service the request, the database session fails.

VTAm

Requires DDS. Specifies VTAM is the communication method used to access the named node.

VTAM can be specified as the access method for resources residing on different CPUs.

TCP/ip or TCPip

Specifies that the TCP/IP protocol is used to access the named node. This parameter is for DDS users only.
