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 LRS Server JES VMCF Clients (TSO, CICS, VTAM, WINDOWS)
LRS/MVS Server • Server parameters set in PDS member pointed to by Server JCL
//VSV PROC START= // VSVLIB $LRS80 //VSV EXEC PGM=VS80DRIV,REGION=9M,PARM=&START //STEPLIB DD DISP=SHR,DSN=VPS.V1R80.LOAD

LRS/MVS Server
SERVER/ VMCF
• Server requires VSAM profile dataset • Dataset stores user-specific information – PFK settings – User preferences
VSAM PROFILE DATASET
Other VPS V1 R6.2 Migration Issues • Keyword changes – ‘CONVERT’ program can update keywords – COMMTYPE and CONVTYPE keywords new in VPS V1 R7.0

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 –
S
ysout
API
• SAPI replaces PSO –

O
ut • 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 VPS

• SAPI is multitasking interface – Many datasets can be open at once
NOTIFY NOTIFY SYSOUT DEST=PRINTER4 SYSOUT DEST=PRINTER9
• 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
VPS JES
Eliminate Exits VPS • SAPI provides dataset information to VPS – Eliminates need for many JES related exits

PCMDS processing Setup commands Data Reset command • Support for printer specific commands in outbound print stream was added to VPS years ago – Implemented in VPS Exit14
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
Printer1 PCMDSTRT=xxx, PCMDEND=xxxx,
• PCMD keywords provide much easier and more flexible alternative to exit14
Exit14
PCMDS Processing
PRINTER1 Default=Landscape PRINTER2 Default=Portrait PRINTER3 Default= Duplex Landscape
• PCMDS allow different settings for each printer – Landscape vs. Portrait default • PCL and PostScript Formats may be used on same printer
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
VPS 7.0 or earlier user created Format Manual update VPS V1R80 Format
Keyword Changes • VPS V1 R8.0 introduces minor printer keyword changes – Some TCPOPTS values now supported on TCPDISC keyword – Other keywords • ERRACTN • MAXLPG
LRS/MVS Server Changes • Server parameter/keyword structure changed from VPS V1 R7.0
– Keywords renamed – Exit points renamed
Other VPS V1 R8.0 Enhancements • BIP™ (Bi-directional Internet Printing) Support – Based on Printer Job Language – Extends capability of TCPIP ‘sockets’ printing – Fix level 098 and above • VPS/AnyQueue™ – High percentage compression between VPS and VPS/AnyQueue
Other VPS V1 R8.0 Enhancements • VPS/PCL – AFP Enhancements • BCOCA support (bar codes) • Enhanced input tray support • VPS/PageCenter Web Access
New Products • VPS/Email – Send SYSOUT datasets via Email • Rich Text Format • PDF • VPS/LCDS – Support Xerox DJDE output via TCP/IP • VPS/XES to AFP – Convert UDK data streams to AFP
Summary • 6.2 support has expired • 8.0 recommended release to run • Services - Normal support process • VPS Webstart - $3,600 – 2 days of dedicated on-line assistance – Knowledge transfer from LRS S.E.
