Processors Not Supported

VAX-11/730

Processor Restrictions

Remote Execution, with a PC as a server machine is unsupported.

Other Hardware Required

A properly configured DECnet/SNA Gateway or VMS/SNA system for access to the 
IBM mainframe environment is required:

DECnet/SNA Gateway  (DECSA-FA) (SPD 30.15.xx)
DEC MicroServer     (DEMSA-Ax) (SPD 25.C6.xx)
DEC MicroServer-SP  (DEMSB-Ax) (SPD 25.C6.xx)
DEC ChannelServer   (DESNA-Ax) (SPD 29.76.xx)

VMS/SNA (SPD 27.01)

Block Space Requirements (Block Cluster Size = 1):

Disk space required for installation:		 2,600 blocks
						(1,300K bytes)

Disk space required for use (permanent):	1,500 blocks
						(750K bytes)

These counts refer to the disk space required on the system disk.  The sizes 
are approximate; actual sizes may vary depending on the user's system 
environment, configuration, and software options.

Memory Requirements for DECwindows Support

The minimum supported memory for this application running in a stand-alone 
DECwindows environment with both the client and server executing on that same 
system is 4 MB.

The performance and memory usage of DECwindows applications are particularly 
sensitive to system configuration.  Less memory may be required on the client 
system (the system where the software is installed and executed) if the server 
(the component that displays the application) resides on another system.  More 
memory may be required on a system with several applications running or may be 
desirable to improve the performance of an application.

The minimum memory supported is 4 MB.  However, the use of this software in 
conjunction with increased memory capability improves performance.  The memory 
size suggested for most typical hardware configurations is at least 6 MB.

CLUSTER ENVIRONMENT

This layered product is fully supported when installed on any valid and 
licensed VAXcluster* configuration without restrictions.  The HARDWARE 
REQUIREMENTS sections of this product's Software Product Description and System 
Support Addendum detail any special hardware required by this product.

* V5.x VAXcluster configurations are fully described in the VAXcluster Software 
  Product Description (29.78.xx) and include CI, Ethernet and Mixed 
  Interconnect configurations.

SOFTWARE REQUIREMENTS 

The DECwindows DECnet/SNA 3270 Terminal Emulator for VMS requires one of the 
following products.  Refer to the respective SPD for prerequisite hardware and 
software.

oo VMS/SNA V2.0  (SPD 27.01.xx)
oo DECnet/SNA Gateway-CT V1.0  (SPD 29.76.xx)
oo DECnet/SNA Gateway-ST V1.1  (SPD 25.C6.xx)
oo DECnet/SNA Gateway V1.5  (SPD 30.15.xx)

For a DECnet/SNA Gateway environment:

oo VMS Operating System V5.1 - V5.2 (and necessary components of VMS DECwindows) 
  
oo DECnet-VAX V5.1 - V5.2

oo DECnet/SNA VMS Gateway Management V2.0 (for use with DEMSA, DEMSB, and DESNA 
  hardware) is required on the gateway load host node.

oo DECnet/SNA Gateway Management V1.5 (for use with DECSA hardware) is required 
  on all VMS systems from which the DECwindows DECnet/SNA 3270 Terminal 
  Emulator for VMS provides access.

For a VMS/SNA environment:

oo VMS Operating System V5.1 - V5.2 (and necessary components of VMS DECwindows)

oo VMS/SNA Software V2.0

For Workstations Running DECwindows:

This product may run in either of the following ways:

oo Stand-alone execution - Running the X11 display server and the client 
  application on the same machine.

oo Remote execution - Running the X11 display server and the client application 
  on different machines.

VMS DECwindows is part of the VMS Operating System but must be installed 
separately.  Installation of VMS DECwindows gives you the option to install any 
or all of the following three components:

oo VMS DECwindows Compute Server (Base kit; includes runtime support) 
oo VMS DECwindows Device Support 
oo VMS DECwindows Programming Support

For stand-alone execution, the following DECwindows components must be 
installed on the machine:

oo VMS DECwindows Compute Server
oo VMS DECwindows Device Support

For remote execution, the following DECwindows components must be installed on 
the machine:

Server Machine                        

VMS DECwindows Device Support       

Client Machine

VMS DECwindows Compute Server

VMS Tailoring

For VMS V5.x systems, the following VMS classes are required for full 
functionality of this layered product:

oo VMS Required Saveset
oo Network Support
oo Utilities

For more information on VMS classes and tailoring, refer to the VMS Operating 
System Software Product Description (SPD 25.01.xx).

OPTIONAL SOFTWARE
