2.121 HOST

Valid for

GLOBALS

Description

The HOST parameter does the following:

  • Identifies the remote NonStop system to communicate with GGSCI.

  • Helps Oracle GoldenGate resolve file names when delivering data over TCP/IP. For installations without Expand connections, the HOST parameter is required for mapping node numbers to node names. If an Expand link exists between systems, use the NODENUM parameter instead of HOST.

  • Identifies the NonStop volume and subvolume where the Oracle GoldenGate environment can be found for remote nodes. When the NETWORKCHECKPOINTS parameter is set, Replicat uses this information to identify the local checkpoint file to update for replication to a file partition. This then allows Replicat to recognize replicated data in a bi-directional system.

Syntax

HOST system_name
[, GGSSUBVOL subvolume]
[, NODENUM node_number]
system_name

Identifies the host system name.

GGSSUBVOL subvolume

Identifies the subvolume. Required with NODENUM.

NODENUM node_number

Identifies the NonStop node.

Examples

Example 1   

The first example below identifies an Oracle GoldenGate installation on remote node \SF as subvolume $DATA3.GGS. The second identifies node number 109 as NonStop system \NY.

HOST \SF, GGSSUBVOL $DATA3.GGS
HOST \NY, NODENUM 109
Example 2   

This example identifies multiple nodes that contain data and an Oracle GoldenGate installation.

HOST \SF, NODENUM 112, GGSSUBVOL $DATA3.GGS
HOST \BACK, NODENUM 113, GGSSUBVOL $VOL03.GGS
HOST \LA, NODENUM 114, GGSSUBVOL $DATA6.GGS
HOST \NY, NODENUM 115, GGSSUBVOL $PROD1.GGS
