DATALOC

Manages and lists the client routing table.

Formats

DATALOC ADD group address
DATALOC DEL group
DATALOC LIST group
DATALOC HOST

Parameters

ADD	adds an entry to the client routing table; the entry maps a group name to a server's IP address
DEL	deletes an entry from the client routing table
HOST	refreshes the name server lookup for hosts; must be run if a server's numeric IP address is changed
LIST	lists the client routing table (default)
group	group name (no default for ADD and DEL; default=all groups for LIST)
address	IP address of the server; specify LOCAL-DATA for the local server

Remarks

DATALOC manages the client routing table, which links ADDE groups to IP addresses of servers. When you enter an ADDE command, the client routing table is scanned to locate the server that will receive the data request. When the server receives the data request, it scans its own mapping table to determine which data the client is requesting.

If an ADDE command specifies a group name that is not in the client routing table, the data request is sent to the local server.

You cannot assign the same group name to more than one server because the ADD option overwrites an existing group name without warning. You may, however, assign more than one group name to a server.
