Information Access Server: System Management

HP 3000 Requirements 

Access Server runs on HP 3000 Series 3X through 7X computers using
Advanced Terminal Processors (ATP) ATP/37 or ATP/M, and Series 9XX
computers using DTCs (Data Terminal Controllers) over a direct or modem
connection or LANICs over a LAN connection.  Minimum memory and disc
storage requirements are shown below.


NOTE  Capacity planning services are available from Hewlett-Packard to
      help you gauge the impact of Access Server on your system.


Hardware Requirements 

Hardware Requirements.     

Be sure your system meets these requirements before you install Access
Server:

Minimum memory.   

Systems running Access Server on MPE/V require a minimum of two megabytes
of memory.  In an HP OfficeShare environment, four megabytes or more are
strongly recommended.

Systems running Access Server on MPE/XL require a minimum of 24 megabytes
of memory.

Microcode.   

MPE/V CST expansion microcode is required.  (Not applicable to Series
9XX.)

Disc Space Required on MPE/V.   

When you install Access Server on MPE/V, the base product uses about
20,000 disc sectors for its permanent files.  Another 6,000 sectors are
used for temporary installation files.

The Information Access data dictionary has a default size of about 13,000
sectors:  9,500 for HDPDIC, and 2,800 for HDPENV. (The DBA can alter the
default data dictionary capacities.)

We recommend that you allow at least 30,000 to 40,000 extra sectors to
provide space for saved tables and work files (particularly when large
tables are involved) in addition to the disc space used by the software.

Disc Space Required on MPE/XL.   

When you install Access Server on MPE/XL, the base product uses about
32,000 disc sectors for its permanent files.  Another 6,000 sectors are
used for temporary installation files.

The Information Access data dictionary has a default size of 13,000
sectors:  9,500 for HDPDIC, and 2,800 for HDPENV. (The DBA can alter the
default data dictionary capacities.)

We recommend that you allow at least 30,000 to 40,000 extra sectors to
provide space for saved tables and work files (particularly when large
tables are involved) in addition to the disc space used by the software.

Hardware Limitations 

Hardware Limitations.   

Keep in mind the following hardware limitations when installing and using
Access Server:

Remote HP 3000s.   

Remote HP 3000s must be located no more than one logical node away from
the host.

Terminals.   

Only terminals that support V/3000 can be used to run the utilities.
Moreover, because the utilities are heavily dependent on the use of
function labels, we strongly recommend that they be run only on terminals
that display function labels.

The HP 2624B terminal with Rev A firmware should never be used to run the
Administrator and Translator Utilities.  The utilities use portions of
V/3000 which do not work with the Rev A firmware on the HP 2624B.

Data Switches and Terminal Multiplexers.   

Access Server supports the HP 2334A, HP 2334A Plus, and HP 2335
multiplexers.  (See "X.25 Support," below.)  Other terminal multiplexers
and data switches may work but are not supported by HP for use with
Information Access.  Any problem found in a non-supported datacomm
environment must be verified in a supported environment before HP can be
consulted concerning the problem.

X.25 Support 

The following PC-to-host connections through HP 2334A, HP 2334A Plus, and
HP 2335 multiplexers are supported for basic serial connections.

   *   Statistical Multiplexer Configuration.  This configuration
       consists of back-to-back HP 2334A, HP 2334A Plus, or HP 2335
       multiplexers, and is supported over a leased, private, or dial-up
       line.  Connections through certified X.25 packet switching
       networks are also supported.  On Series 3X through 7X systems, the
       connection is to an ATP. On Series 9XX systems, the connection is
       to a DTC. Note that on Series 9XX systems, only the HP 2334A Plus
       is supported.

   *   Cluster Controller Configuration.  This configuration consists of
       a synchronous link between an HP 2334A, HP 2334A Plus, or HP 2335
       multiplexer and an INP on a Series 3X through 7X system.
       Connections are supported over leased, private, or dial-up lines.
       Support for certified X.25 packet switching networks can be
       obtained for this configuration by performing local testing.
       Contact your HP representative for details.  Note that the cluster
       controller configuration is not supported on Series 9XX systems.

For a list of certified X.25 packet switching networks, see the data
sheet for the HP 2334A, HP 2334A Plus, and HP 2335 multiplexers.

Figure 2-1 on the next page depicts supported configurations for
PC-to-host connections.


          Figure 2-1.  Supported PC-to-Host Configurations 

Because Access Server will translate control characters to non-control
values, there are no special profile configuration requirements for the
HP 2334A, HP 2334A Plus, or HP 2335.  Any HP 2334A/HP 2334A Plus/HP 2335
profile that supports a standard MPE session will function properly with
Information Access.

PC users using X.25 should be aware of the following:

   *   To connect to Access Server, they must have AdvanceLink, a
       terminal emulator, or use connection files to get the MPE colon
       prompt and establish their remote session.  (The one exception:
       If HP 2334A, HP 2334A Plus, or HP 2335 multiplexers are
       back-to-back over a dedicated line, they can be configured so that
       the PC-to-host connection looks like a direct connection.  For
       details, see the HP`2334A/HP`2334A Plus/HP`2335 documentation.)

Software Requirements 

Access Server uses the following software on the HP 3000 Series 3X
through 7X and 9XX computers:

   *   The IMAGE database management system.

   *   The MPE/V (version G.03.03 or later) or MPE/XL (version A.03.00 or
       later) MIT. This MIT release includes compatible versions
       of V/3000 (the utility that supports view screens) and
       PCSERVER.PUB.SYS (the HP 3000 datacomm software for products using
       basic serial connections).

   *   The Pascal runtime library.

   *   HP OfficeShare LAN/3000 software if HP OfficeShare networking is
       used.

Remote 3000 Link.     

If you're using the Remote 3000 Link, NS/3000 networking software must be
installed on the host and remote HP 3000s.  Remote HP 3000s can be
located no more than one logical node away from the host.

MPE Configuration.     

When you configure MPE for Access Server, consider these criteria:

   *   When running under basic serial software, configure ports from
       which Information Access will run as terminal type 10.  The
       datacomm software expects transmissions to be from a terminal type
       10, and, over a modem, could time out on a transmission from a
       port specified as something other than type 10.

   *   Consider enabling disc caching on HP 3000 systems that support it,
       based on your system I/O and CPU load pattern.

   *   As with any new product installation, review the system table
       configuration and make any necessary adjustments.  (Guidelines are
       given in Chapter 4.)
