VPS® V1 R8.0 Migration Issues

Migration Issues

• Migrating from VPS V1 R6.2– LRS/MVS Server

• Migrating from VPS V1 R7.0– SAPI– PCMDS– New products– Other enhancements

Migrating from VPS V1 R6.2

• New in VPS V1 R7.0 and above– LRS/MVS Server– VPS keyword changes

• COMMTYPE• CONVTYPE• Others

Migrating from VPS V1 R6.2

• VPS V1 R7.0 implements LRS/MVS Server– Most VMCF logic

moves to LRS Server– LRS/MVS Server

removes need for authorization SVC.

– LRS/MVS Server reduces CPU burden of ‘VMCF Client’, e.g.. TSO, CICS

VPS JES

VMCF Clients (TSO, CICS, VTAM, WINDOWS)

LRS/MVS Server

• Server parameters set in PDS member pointed to by Server JCL

//VSV PROC START=$LRS80 //VSV EXEC PGM=VS80DRIV,REGION=9M,PARM=&START //STEPLIB DD DISP=SHR,DSN=VPS.V1R80.LOAD // DD DISP=SHR,DSN=VSV.V1R80.LOAD //VSVLIB DD DISP=SHR,DSN=VSV.V1R80.CNTL //PROFILE DD DISP=SHR,DSN=VSV.V1R80.PROFILE //SYSUDUMP DD SYSOUT=D //*

LRS/MVS Server

• Server requires VSAM profile dataset

• Dataset stores user-specific information– PFK settings– User

preferences

Exit Migration

• Most non-JES-related exits can be migrated by assembling them with new release’s macro library

• Customized exits should be reviewed

Migrating to VPS V1 R8.0

New Features in VPS V1 R8.0

• SAPI processing • PCMD keywords• Minor keyword changes• Other enhancements• New Products

– VPS/Email– VPS/LCDS– VPS/XES to AFP

SAPI Processing

• SAPI is a new interface for communicating with JES– Sysout API

• SAPI replaces PSO– Process SysOut

• PSO still exists; VPS defaults to SAPI

SAPI Benefits

• Reduces CPU usage– Eliminates polling of JES for datasets

• Eliminates VPS user exits– Many JES-related exits no longer

needed

• Enhanced throughput– SAPI is multi-threaded

• Reduces or eliminates staging

Reduced CPU Usage

• PSO interface requires one request to JES for each printer every ‘INTERVAL’ cycle.

Reduced CPU Usage

• SAPI interface requires one request to JES per printer

• JES ‘remembers’ outstanding requests, notifies VPS when output arrives

Increased Throughput

• SAPI is multitasking interface– Many datasets can be

open at once

• PSO interface passes one dataset at a time– Creates need for

staging

Eliminate Exits

• Many pre-V1R80 VPS user exits use MVS cross memory services.– Exits read control

blocks in JES’ memory

– Exits ‘bring back’ SYSOUT dataset information to VPS

Eliminate Exits

• SAPI provides dataset information to VPS– Eliminates

need for many JES-related exits

PCMDS processing

• Support for printer-specific commands in outbound print stream was added to VPS years ago – Implemented in

VPS Exit14

Setup commands

PCMDS Processing

• Sample Exit14 constructed to support external storage of printer setup commands

• Allowed setup commands to be modified dynamically

PCMDS Processing

• Setup commands stored in external modules called ‘Formats’

• Many customers

have modified LRS-supplied Formats.

PCMDS Processing

• VPS V1 R8.0 introduces new method for supporting printer setup commands

• Most functionality moved from Exit14 to PCMD keywords– Formats still used

PCMDS Processing

Exit14

• PCMD keywords provide much easier and more flexible alternative to exit14

PCMDS Processing

• PCMDS allow different settings for each printer– Landscape vs.

PCMDS - Migration

• Format module structure changed in VPS V1 R8.0

• LRS sample Formats supplied in new structure

• User-created Formats must be updated to use new structure
