Preparing to Install SNA View on the Mainframe

This chapter describes what you do to prepare to install CiscoWorks Blue SNA View on a mainframe. Before you install, configure, and validate CiscoWorks Blue SNA View, read the following main topics in this chapter:

• Mainframe Hardware Requirements

• Mainframe Software Requirements

• Mainframe Installation Summary

Mainframe Hardware Requirements

You need the following hardware to install the SNA View mainframe application:

• Tape drive--Cartridge tape reader capable of reading a 3480 cartridge with a density of 6250 bits per inch (bps).

• Disk space--Twenty cylinders of 3380 direct access storage, or equivalent. This includes space for the SMP/E Target and Distribution libraries.

Mainframe Software Requirements

This section lists mainframe software that you need to run the SNA View mainframe program.

Required Mainframe Software

You must have the following mainframe software for use with the SNA View mainframe application:

• Operating system--MVS/ESA 4.1 or later, plus SMP/E, Release 7 or later

• Access method--VTAM 4.1 or later

• Protocol stack--One of the following communication protocols:

  • SNA LU 6.2

  • TCP/IP (Cisco IOS for S/390, IBM TCP/IP for MVS Version 3, Release 1 or later, or Interlink TCP/IP for MVS)

All CiscoWorks Blue SNA View workstations must have either TCP/IP or LU 6.2 connectivity to the SNA View mainframe. The TCP/IP connectivity is provided through the workstation operating system. The LU 6.2 connectivity is provided by one of the following products:

• On AIX systems--IBM Communications Server for AIX, Version 4, Release 2 or later.

• On HP-UX systems--HP-UX SNAplus2, including SNAplus2 Link and
  SNAplus2 API.

---

Note LU 6.2 connections are not supported for workstations using Solaris.

---

Optional Mainframe Software

The following mainframe software is optional:

• Network management system (NetView 2.3 or later, or SOLVE:Netmaster 2.2 or later).

• Network Control Program (NCP) 4.3 or later if you use RSRB Maps and SNA View PU and LU correlation.

Mainframe Installation Summary

This section summarizes the steps you follow to install SNA View on the mainframe and to update the other mainframe software. Use this installation summary to ensure that you have performed all the SNA View mainframe installation tasks.

Updating MVS and VTAM

This section provides a summary of steps required to change the MVS and VTAM system software. See the chapter "Updating the Mainframe Application Software" for details.

Step 1 Use SMP/E to unload and install the SNA View mainframe tape files to the mainframe.

Step 2 Configure LU 6.2 connectivity from the SNA View workstations to the mainframe.

• Update the VTAM MODETAB table entry.

• Define the PU and LU for each SNA View workstation.

Step 3 Configure TCP/IP connectivity from the SNA View workstations to the mainframe.

• Reserve port numbers for SNA View host connection interface and host command server.

• Assign a TCP/IP high-level qualifier.

Step 4 Update SYS1.PARMLIB for MVS.

• Authorize SNA View LOADLIB (prefix.NSPS120I.NSPSLOAD).

• Set the performance group.

• Add an SNA View entry to the program properties table.

Step 5 Update VTAM.

• Add the PPOLOG=YES VTAM startup option in ATCSTRxx.

• Add the application major node definition for SNA View.

• Activate the SNA View major node (NSPAPPL).

• Install SNA View XID Configuration Services exit routine.

• Allocate the VSAM data sets.

Do Not Filter These VTAM Messages

The SNA View mainframe program needs to receive the following VTAM messages over the PPI or PPO interface. Do not block these messages from reaching the SNA View mainframe program.

• IST093I

• IST105I

• IST259I

• IST590I

• IST621I

Do Not Filter This SNA View Message

The SNA View mainframe program needs to receive the following message over the PPI or PPO interface. Do not block this message from reaching the SNA View mainframe program.

• NSP2000I

Updating SNA View

Update the NSPPARM configuration file by customizing the SNA View mainframe parameter cards. See the chapter "Updating the Mainframe Application Software" for details.

Updating NetView

The following steps summarize the changes to NetView. This process requires stopping and restarting NetView. See the chapter "Updating the Mainframe Application Software" for details.

Step 1 Verify that the NetView PPI is active.

Step 2 Update the files in the DSIPARM data set.

• Define the SNA View optional task in the DSIDMN member.

• Define NSPMQS in the DSICMD member.

• Define and activate the autotask operator (NSPAUTO1) in the DSIOPF member.

Step 3 Add the NSPSCMD CLIST to the DSICLD data set.

Step 4 Add or update NetView exit routines (DSIEX06, DSIEX11).

Step 5 Update the initial CLIST (the default initial CLIST is CNME1034).

Step 6 Assemble and link-edit SNA View programs with NetView.

Updating Netmaster

The following steps summarize the changes to SOLVE:Netmaster. This process does not require stopping SOLVE:Netmaster. See the chapter "Updating the Mainframe Application Software" for details.

Step 1 Verify that the SOLVE:Netmaster PPI is active.

Step 2 Update SOLVE:Netmaster PPOPROC from NSPKPPO.

Step 3 Copy the following SNA View PROCS to the SOLVE:Netmaster command data set: NSPKCMD, NSPKCM1, and NSPKPPI.

Step 4 Update CNMPROC to start the SNA View NSPKPPI and NSPKCMD PROCs.

Step 5 Verify SOLVE:Netmaster updates.
