IBM i Program Conversion Preview

•Program conversion is required for IBM i 6.1 – Program conversion automatically upgrades software to

exploit latest system enhancements– IBM i 6.1 is not required for POWER6, can run i5/OS V5R4

•Conversion requires program's creation data (observability) – Since V5R1, all programs being created have had their

creation data automatically saved•Tool to analyze program conversion for i5/OS V5R3 / V5R4

– Identifies any potential issues and estimates conversion time

•Program conversion is performed during install/restore of applications, at first use or at scheduled time

Ensures unprecedented system integrityEnables exploitation of future system and processor capabilities

Delivers improved performance

Planning Tools Available

•Tools are available to help validate your system •The Analyze Object Conversion (ANZOBJCVN) CL command is provided for i5/OS versions V5R3 and V5R4. –V5R3

MRI PTF SI27515 requires: PTF SI27513 (code). Code PTF SI27513 requires two PTFs:

– PTF for spooled files estimations SI25504.– PTF for analyze integrated file system names SI27473.

–V5R4 MRI PTF SI25550 requires: PTF SI25543 (code). Code PTF SI25543 requires two PTFs:

– PTF for spooled files estimations SI25502.– PTF for analyze integrated file system names SI26706.

•More PTFs may be required (language support) –Refer to Informational APAR II14306– http://www-

Historical Perspective

•6.1 MI program refresh – Easier for customers

been planned for awhile– Includes more investment in program

environment– Much less overall system change

•NOT like previous MI program refreshes– System/38 to AS/400 (V1R1, 1988)– CISC to RISC (V3R6, 1996)

48-bit to 64-bit addresses


IBM Power Systems

17

Why?

•Upgrade software without source changes– Capitalize on Machine Interface (MI) architecture

•Enhance:– Integrity– Performance– Function

•System technical vitality– MI architecture is not new– Provides refresh and

improvement capabilities that are among the best in the industrythis refresh while using these capabilities is also

providing foundation to extend them


IBM Power Systems

18

Integrity improvement examples

•Eradicate any altered programs that exist now– No chance to interfere with the system

•Extend unique ability to remove any future code corruption– Any runnable MI application can be refreshed at any time

Vendor programs with no source can be converted to check for possible corruption

– Prevent load of non-i ‘system state’ programs masquerading as ‘system state’ programsSystem state = higher privileged running environmentCan only be loaded as

part of operating system– Make system more robust


IBM Power Systems

19

Performance improvement examples

•Faster activation, procedure calls, pointer use

•More efficient memory handling– Remove limitation of software

teraspace emulation and use direct hardware support

– Improves speed of performance for ILE, PASE, etc

•Generate processor-specific code– Can “opt out” of adaptive code generation if desired

•New create options, no source changes required:– Optimize procedure call argument passing, between

modules (+20%) – ARGOPTPassing space pointers into a general purpose

register– Defer service program activation significantly improving

startup of applications – BNDSRVPGM(*DEFER)


IBM Power Systems

20

Adaptive Code Generation details•Defaults:

– Use features of hardware on which program is created/converted

– Convert when moving to different hardware only if required

•Use only features found on all systems (opt out)– Use LICOPT(‘CodeGenTarget=Common’) on CRT* or

CHG* commands– Set QIBM_BN_CREATE_WITH_COMMON_CODEGEN

environ var to 2•Optimize to latest hardware if not created there

– CHG(SRV)PGM FRCCRT(*YES) if observable creation data

– Restore (from save file, e.g.) using one of:RST{OBJ,LIB} FRCOBJCVN(*YES *ALL)

•First set system value QFRCCVNRST to 2 or higher•See ILE Concepts document


IBM Power Systems

21

Further create-time options detail

•CRTPGM and CRTSRVPGM parameters– Only available for target release 6.1– Optimize procedure calls between modules, within a

(service) program: ARGOPT(*YES)– Choose deferred activation, by service program:

BNDSRVPGM( (libA/srvpgmA *IMMED) (libB/srvpgmB *DEFER) ) for best performance, specify all *IMMED uses first

•See ILE Concepts document


IBM Power Systems

22

About Conversion

•Replace existing program object without compile•One-time process, but required either direction

V5R4 or V5R3 6.1 V5R4 or V5R3 6.1

•Part of all 6.1 systems– No options or added fees

•Average per-program convert times, large sample– Sub-second on fastest processors, <4 seconds on

slowest– Programs with many modules may take longer

Conversion exception cases

•Creation data (observability subset) not available– Creation data is available to Licensed Internal Code, unless

program (or constituent module) target release is before V5R1--AND--

creation data was explicitly removed– Must compile from source if creation data gone

•Program relies on unsupported alterations– Conversion removes such modifications– Must use supported interfaces instead


IBM Power Systems

25

Conversion method choices

• Run new ANZOBJCVN tool on V5R4 or V5R3– Identifies potential conversion issues, estimates times

• Choose combination of methods on 6.11. Scheduled

STROBJCVN by library1. First call/activation

pay-as-you-go, some initial delay1. Restore/install

FRCOBJCVN(*YES *ALL) or change QFRCCVNRST >= 2

• Must regenerate applications that won’t convert– compile from source or acquire


IBM Power Systems

26

Creation data status details

•Before using ANZOBJCVN can use DSPPGM or DSPSRVPGM

•Creation data unavailable for conversion if:– For ILE (service) programs, ‘All creation

data’ is *NO– For OPM programs, ‘Observable

information’ is *NONE


IBM Power Systems

27

Analyze Object Conversion – ANZOBJCVN (V5R3 & V5R4)

•Two ways to run ANZOBJCVN –Collect and Report

•Run collect in Batch – SBMJOB CMD(ANZOBJCVN OPTION(*COLLECT) LIB(*ALLUSR) SPLFILE(*YES) OBJ(‘/’)) JOB(ANZOBJCOL)

Analyze Object Conversion…


IBM Power Systems

29

Program conversion methods

• Strongly advised to make all necessary preparations for object conversion prior to starting the upgrade or migration process.

• Conversion to 6.1 compatible format is a one-time only operation.

• The following methods are available to perform program object conversion:1. Using the 6.1 Start Object Conversion (STROBJCVN) CL

command to manually initiate conversion on program objects within libraries and the integrated file system.

2. During a restore3. The first time the program is run


IBM Power Systems

30

Object Conversion

1. Scheduled conversion– The 6.1 Start Object Conversion (STROBJCVN) command

is provided to manually initiate conversion on program objects within libraries and Java programs in the integrated file system

1. Restore– During an upgrade to 6.1, some IBM-supplied program

objects will either convert during the upgrade, or will be provided in a 6.1-compatible format on your install media.

1. Conversion the first time a program is run– Program objects that have not been converted earlier,

during restore or due to running the STROBJCVN command, will be converted when the program is first run.

Refresh method choices - ISVs•Application converted on each customer system

– Test conversion, inform customers of best methodconsider application time-out potential and

adaptive code generation•Rebuild and redistribute programs (and fixes)

– Required if program altered or lacks creation data – Recommended if:

VERY large programs usedapplication profiling data applied but was

removedyou add a digital signature, still needed on

customer systems– Perhaps build, ship both pre-6.1 and 6.1 versions

must build on separate partitionshave application install code select correct

version


IBM Power Systems

33

Summary

•Upgrade software without more programming– All MI programs refreshed, most by conversion– Deliver enhanced integrity, performance and function

•Increase system value with EXTREME integrity and flexibility – Now can convert any MI program (except IBM i) any

time– Enable much easier leverage of new hardware and

future system structure changes •Demonstrate IBM i technical vitality
