IBM i Roadmap

2006 2007 2008 2009

V5R4 6.1

6.1.1 V5R4M5

� Clients requesting fewer operating system releases; and longer support cycles

– Major release upgrades can be disruptive for a business

� Clients requesting access to newest technology

� Before 7.1

– Small changes could be added using PTFs

– Major new support required a “point release”

V5R4 6.1 7.1 i next i next + 1

6.1.1 V5R4M5

………

� At 7.1 Technology Refreshes were added

– Built from experiences with PTF Groups

– Treated as a mini-release for planning & testing purposes

– Simpler to install on a current release and less disruptive

– Now i had a means to stretch releases, yet deliver enhancements

… but …

Technically ….

�Technology Refreshes are only for SLIC– and really only for some of SLIC

� WHAT?

– What do you mean by SLIC?

– What about that DB2 stuff I saw in the announcement?

Or the Java stuff?

Or PowerHA?

Or …

Technology Refresh Concept as Delivered by TR Groups

� Beginning with IBM i 7.1 GA, future point / modification releases are replaced with a new delivery mechanism:

“Technology Refresh”

� Definition: A collection of OS software for “new function enablement” that is

– packaged together,

– tested together, and

– delivered as a single PTF Group.

� A Technology Refresh may include:

– Support for new hardware and firmware(for example, new I/O devices or newly

announced models)

– Support for new virtualization functions

– Performance improvements

– New function enablement


IBM Power Systems

Technology Refresh: Technically Speaking


IBM Power Systems


What Is a Technology Refresh – Really?

� Overloaded Term

– System Management definition

TR PTF Group + GA CUM

(+ GA Resave if upgrading to 7.1)

– General communications

Everything announced when TR PTF

Group is delivered

developerWorks uses the term

TECHNOLOGY UPDATE

� Think of the Technology Refresh

as the TR PTF Group + GA CUM

(+ GA Resave if upgrading to 7.1)

– Orderable entities – bundle various

PTFs, including a TR PTF

– Together they provide enablement of

new hardware, firmware, and

virtualization

A Look Under the Covers – The Technology Refresh PTF

� Provides much of “magic” of the Technology Refresh

– Large multiple-component Licensed Internal Code (LIC) PTF

– Allows development and testing like a modification release, but distribution like a PTF

� Part of the “magic” is accomplished by breaking the supersede chain after each Technology Refresh PTF

– Therefore, it must be perm applied to install follow-on PTFs

– PTF Install will enforce rules and try to do this for you

� Built and approved well before GA, so can be included in GA resave

– It is NOT a “marker PTF” – it is an actual, functional PTF

– At GA time, it is bundled in TR PTF Group along with follow-on PTFs and additional function

– IBM DOES NOT recommend installing the individual TR PTF before GA or without the corresponding TR PTF Group, unless the TR PTF is required by a PTF Group or a follow-on PTF


IBM Power Systems


Technology Refresh PTF (cont.)

� Follow-on PTFs: Non-Technology Refresh PTFs

containing common objects with the

Technology Refresh PTF

� Follow-on PTFs:

– Will NOT supersede the Technology Refresh PTF

– Will have new *TRREQ (Technology Refresh requisite) designation

– New *TRREQ type supported on DSPPTF and QPZRTVFX API

In RETAIN, follow-on PTF will prereq the Technology Refresh PTF (RETAIN will

not support new *TRREQ).

– Cannot be loaded until the Tech Refresh PTF is permanently applied

– Can be *IMMED even though Tech Refresh PTF is *DELAYED.

� Technology Refresh PTF identified via:

– New PTF attribute (DSPPTF command, QPZRTVFX, QpzListPTF APIs)

– Reserved prefix range: MF99nnn – e.g., MF99004 for 7.1 is PTF for TR4

IBM Power Systems


A Very Good FAQ

�Are Technology Refreshes available for the entire IBM i operating system?

– No, Technology Refreshes are currently only available for Licensed Internal Code

– However, other system function may be GAed at the same time as a TR


IBM Power Systems


Strategically Speaking

� Historically

– DB2 was already producing PTF Groups for new off-release function

– Other technologies were delivering capabilities in groups, or individual PTFs

– No coordination: themes, communication, documentation

� IBM i needed to emulate Technology Refreshes throughout the Operating System

– Coming to fruition in TR4 timeframe

– Let’s look at developerWorks – THE place to go for TRs and more new function

developerWorks: More Technologies, More Groups

• Over time, technology groups which have been delivering functions between

releases are being gathered here.

• BRMS & PowerHA, for example, have been added since TR3, gathering

material from “marketing” pages where they were initially created.

• In any specific TR, there may or may not be enhancements in some technologies.

What Are Best Practices ?

� At a minimum should consider applying:

– CUM, HIPERs, DB Group, TR Group –roughly every 6 months

– Do not “pick and choose” individual PTFsfrom the groups – load everything

– This is the best way to avoid unplanned downtime

� Depending on needs & your environment

– Other groups

(Security, Java, HTTP, TCP/IP, Print, BRMS, etc.)

– Individual PTFs for particular support

– Consult developerWorks and PSP web pages for info to help make decision

� Load all into same image catalog

– Apply from there

– Let the system decidehow to apply most efficiently

The TR PTF Itself

� The TR PTF will be available before GA

– TR PTF is created well before GA, so it can be included in the GA Resave

– It is extensively tested on older levels of supported hardware before that – so it is safe to install on older supported systems

– BUT IBM does not recommend that it be installed without the TR PTF Group, unless it is required by another PTF or PTF Group being installed.

� The TR PTF can become a requisite of another PTF before (or after) GA

– If a part / module in the TR PTF is changed by a subsequent PTF,the TR PTF becomes a special kind of requisite, called a *TRREQ (looks like prereq in Retain)

– Follow on PTFs can be *IMMED even though Tech Refresh PTF is *DELAYED.

� The TR PTF can be included in PTF groups (like HIPERs and CUMs)

– If a PTF in the HIPER group or CUM calls out the TR PTF as a *TRREQ, then the TR PTF will be pulled into the HIPER group or CUM

– In fact, this likely will occur TR

IBM Power Systems


Some Other Things to Remember

� The TR PTF may be required for debug or future fixes

– Development / support will generally try to debuga problem when the system is in the failing state

Sometimes development builds traps or special debug code to help isolate the problem

– If system is back-level, may need to bring fix level

up to date before can get permanent fix – if TR PTF

is in PTF chains of fix, this will mean applying the TR PTF

� Later Technology Refreshes are supersets of previous ones

– This means that if a system is back level on Technology

Refreshes, only the latest TR must be installed to

bring the system up to date

� Make sure the TR PTF is permanently applied

– Will need to be perm applied before any

follow on PTFs that require it can be

applied

IBM Power Systems


Details for Planning Purposes

� Before installing the TR PTF, TR Group, CUM, etc. make sure the Double IPL Automation PTF is installed on your system – SI43585

– It will save you time when applying TRs, Groups, PTFs, etc.

– Has been in HIPER group since 05/10/11

– In TR Group for TR 2 – 05/13/11

– In CUM and Resave available at same time as TR 2

� Must be installing from an image catalog, in order to take advantage of the “Double IPL”automation support

– If installing from a remote virtual optical device on a different partition, make sure the server partition has PTF SI42302 applied (contains required image catalog and optical code for “Automatic Double-IPL”).

� Read InfoApar II14482 when planning your upgrade to 7.1

– Lists PTFs and process needed to avoid a potential problem trying to apply a TR immediately after doing an upgrade to 7.1 from 5.4.x or 6.1.x,

– This was initially thought to be a TR problem, but was actually related to image catalog support

If You Have Questions

� Don’t just assume

– Consult the web pages, FAQs, Info Center, etc.

– And if still confused – ASK

IBM Power Systems


Summary

� Without Technology Refreshes

– IBM i would be delivering another release this year – 2012

There would have been impacts to V5R4 & 6.1 EoS

– Partition Mobility would not be available on 7.1

Along with Suspend/Resume & other virtualization enhancements

– Coordination of deliverables would have been unlikely

“Same As Always” would have occurred

� With Technology Refreshes

– Full-release function has been delivered

In a staged approach

– Isolation of new function allows for mini-release testing

While ensuring that TRs do not require requalification

– No Release Upgrade is required

Disruption of release is removed

IPL required to complete PTF install processing.

•New CPF362E (IPL required) message is English only. We save GO PTF parms in an

internal space to use on the

next normal, unattended IPL to finish the PTF Install. So …

don’t delete the image catalog

until the PTF install is complete. If using remote

optical device, make sure

server partition has image

catalog with PTFs still loaded when you IPL the client

partition.

•Note if IPL required for special

handling pre-apply PTF (cumepkg), same message.

Just the FAQs – the TR PTF

� Is TR PTF available before GA, and if so, is it safe to install?– Yes, and yes– TR PTF is created well before GA, so it can be included in the GA

Resave– Extensively tested on older levels of supported hardware before that – so it is safe to

install on older supported systems– BUT IBM does not recommend that it be installed, unless it is required by another

PTF or PTF Group you are installing.

� Can the TR PTF become a requisite of another PTF before (or after) GA?– Yes– If a part / module in the TR PTF is changed by a subsequent PTF, the TR PTF

becomes a special kind of requisite, called a *TRREQ

� Can the TR PTF be included in PTF groups (like HIPERs and CUMs)?– Yes– If a PTF in the HIPER group or CUM calls out the TR PTF as a

TRREQ, then the TR PTF will be pulled into the HIPER group or CUM – in fact, this likely will occur


IBM Power Systems

63

Just the FAQs – Install and Requisites

� Will the TR PTF be required for debug or future fixes?– Perhaps

– Development / support will generally try to debug

a problem when the system is in the failing state

• Sometimes development builds traps or special debug code to help isolate the problem

– If system is back-level, may need to bring fix level

up to date before can get permanent fix – if TR PTF is in PTF chains of fix, this will

mean applying the TR PTF

� How are later Technology Refreshes related to previous ones?– Later Technology Refreshes are supersets of previous ones for the same base release

• This means that if a system is back level on Technology Refreshes, only the latest one must be installed to bring the system up to date

� Are Technology Refreshes available for the entire IBM i operating system?– No, Technology Refreshes are currently only available for Licensed Internal Code

– However, other system function may be GAed at the same time as a TR

Just the FAQs – Recovery and Best Practices

� How do I remove a Technology Refresh from my system?– ***DON’T*** – the TR will eventually be required for future fixes (but can temporarily)

• Install a save of the system made before the Technology Refresh install• Install a previous Resave level or the base install media, and bring the system up to date by

applying appropriate PTFs, CUMs, groups

� How do I restore my system back to a known level after a failure?– If system was at current Technology Refresh level, install the latest Resave,

plus CUM, plus TR PTF Group, and any other PTFs, groups, etc.– To restore to an earlier level, must archive media or a save of the system

� What are some BEST PRACTICES?1. Keep systems up to date with latest Technology Refresh PTF Group2. When installing a Technology Refresh, install either the

TR Group plus the CUM, or the Resave plus the TR Group plus the CUM; do not install just the TR PTF

3. Install the Double IPL Automation PTF SI424454. Make sure the Technology Refresh PTF is permanently

applied to your system5. Install from an image catalog, rather than from physical

media, for simplicity and improved performance


IBM Power Systems

65

Potential “Gotchas” to Consider

� DON’T confuse the Technology Refresh PTF with the Technology Refresh PTF Group and the overall Technology Refresh itself

– The Technology Refresh for a particular GA is the Technology Refresh PTF Group plus the corresponding GA CUM

• See the TR web pages for the appropriate levels– Timeline works like this:

• TR PTF is approved and becomes visible well before GA, to include in GA Resave

• TR Web Pages are updated with information on new TR levels at Announce

• TR PTF Group, Resave, and CUM become available at GA

� DON’T install the Technology Refresh PTF by itself– The Technology Refresh PTF by itself may not supply complete support or include

the latest fixes for a particular Technology Refresh.– IBM recommends that customers should NOT install the

Technology Refresh PTF by itself, but instead should install the Technology Refresh PTF Group and the matching CUM (or, if upgrading from older release, the Resave + TR Group + CUM)


IBM Power Systems

66

Potential “Gotchas” to Consider -2-

� DON’T install the Technology Refresh PTF before GA– The Technology Refresh PTF will be available before GA,

so it can be included in the GA Resave and CUM– However, IBM does not recommend installing the TR PTF

before GA unless it is required by a follow-on PTF, because:• The TR PTF is not needed for existing hardware or function• The TR PTF by itself may not contain complete support for new hardware or

function• The new hardware or function the TR PTF enables is not supported until after GA

– If the Technology Refresh PTF is not required to install a follow-on PTF or PTF Group, customers should wait until the Technology Refresh GA and install the TR PTF Group + GA CUM at that time

� DO permanently apply the Technology Refresh PTF as soon as convenient– This will save time later when applying follow-on PTFs

that require it (*TRREQ it)


IBM Power Systems

67

Potential “Gotchas” to Consider -3-

� DO have the Double IPL Automation PTF installed on a system before trying to install the TR Group, TR PTF, Resave, CUM, HIPER Group, etc.

– This will avoid confusion and potentially additional time required,

when upgrading to a new TR level or installing a follow-on PTF that

requires a TR (*TRREQ)

� DO keep your system up to date with latest Technology Refreshes– This can help reduce debug time for system problems, and can avoid

unnecessary outages for system problems that already have fixes available

– Installing a Technology Refresh as soon as it is convenient may avoid having to install it at an inconvenient time, in order to get a needed fix

� DO install a Technology Refresh from an image catalog rather than physical media, if possible

– It will be simpler and will improve performance

– Using an image catalog is necessary for the

“Double IPL” automation support
