PS MAIL 6530 and
PS MAIL 3270
Configurations
PS MAIL 6530 and PS MAIL 3270 are mail clients that provide mail exchange between
terminals using a full-screen mode. Both clients use the same server classes defined
with Base TRANSFER. Each, however, requires its own programs. PS MAIL 6530 and
PS MAIL 3270 also use separate text servers: M6530-TEXT and M3270-TEXT.
These clients add the following objects to the TRANSFER PATHWAY configuration:
PS MAIL 6530
M6530-TCPs
M6530 programs
M6530 text server
PS MAIL 3270
M3270-TCPs
M3270 programs
M3270 text server
These full-screen mail client configurations are shown in Figure 2-2. One program is
defined for each TCP. When multiple TCPs are defined—for example, three
M6530-TCPs in the PS MAIL 6530 definition—three M6530 programs are
automatically defined by the installation procedures.
In configuring the PS MAIL 6530 and PS MAIL 3270 mail clients, you must consider
the following PATHWAY parameters:
The PATHWAY parameter MAXTERMDATA must be set to 64000.
For remote logon, the value of MAXEXTERNALTCPS in the PATHWAY system
at the user’s home node must be set to a value greater than zero. The default is 10.
To determine the value of MAXEXTERNALTCPS, decide how many external
TCPs you want to have concurrently communicating with each other.
For remote logon, the value of MAXPATHWAYS for the TCPs on the local node
must be set to a value greater than zero. The default is 0.
To determine the value of MAXPATHWAYS, decide how many remote
PATHWAY systems need to access the local node concurrently.
Remote logon allows PS MAIL 6530 and PS MAIL 3270 correspondents to log on to
their depots from another node without requiring them to log on to GUARDIAN 90 on
their home node. If your users access PS MAIL 6530 or PS MAIL 3270 remotely and
want to use the EDIT function or print their mail at a remote location, they must have
network passwords associated with the GUARDIAN 90 ID in their TRANSFER depots.
If network passwords are not assigned, users can use only the processes and devices
on their home node. Without network access to every node where remote mail users
are located, some terminal OPEN and CLOSE operations fail with a security violation.
