Description

The SHOW SEGMENT command displays the routing key segment deﬁnitions.

The routing key definition is common to all servers in a facility.

The routing key speciﬁes the data within a message sent from clients used to route the message to a particular key range server.

The position, length and data type of each key segment is displayed.

Qualiﬁers

/CLUSTER /NOCLUSTER (D)

Speciﬁes that the command is executed on all the nodes in the cluster.

If neither /NODE nor /CLUSTER is speciﬁed then the command is executed on the nodes speciﬁed by the latest SET ENVIRONMENT command. If no SET ENVIRONMENT command has been entered then the command is executed only on the node where the command was issued.

Note: In environments that do not support clustering, use of the /CLUSTER qualiﬁer will cause the relevant command to be executed on the local node only.

/FACILITY /FACILITY="*" (D)

Speciﬁes the facility name for which information should be displayed.

By default, information is displayed for all Facilities.

/NODE[=node-list] /NODE=default-node-list (D)

Speciﬁes that the command is executed on all nodes speciﬁed in node-list. If node-listis omitted then the command is executed only on the node where the command was issued.

/OUTPUT[=ﬁle-spec] /OUTPUT=stdout (D)

Speciﬁes that the resulting information is written to the ﬁle file-spec. If /OUTPUT or file-specis omitted then the standard or default output is used.
