To finish out 2008, let’s appear ahead to some upcoming end of service dates that may have an effect on shops working i5/OS V5R3 in 2009 and retail outlets that are nevertheless using AnyNet to connect older twinax-based mostly printers and different devices to device i and vigour i machines. in case you’re in these classes, remember to be aware of the following issues.
a brand new yr, a new i5/OS improve?
If any of your partitions are running i5/OS V5R3, be aware that IBM will discontinue help for i5/OS V5R3 on April 30, 2009. Of route, this doesn’t suggest that your software will not work. It does ability that IBM will now not take aid calls for the working device and it can become greater complex to attain gadget upgrades in the future. After discontinuation, direct enhancements (the place you upgrade from i5/OS V5R3 to the latest software release) may no longer be accessible or supported, reckoning on how lengthy you wait to upgrade your operating gadget. If direct improvements to a goal unlock aren't any longer purchasable, you could need to function a multi-step improve where you first improve to an interim unlock earlier than you function a second improve for bringing the operating gadget up to its target level.
additionally word that your equipment improve planning can also be complicated in case you’re working a production partition alongside a development partition or a means BackUp (CBU) gadget laptop. In these environments, you'll have to function an upgrade for every V5R3 computing device and the sequence of the upgrades may still be here:
Upgrading this way means that you can verify the brand new operating equipment on both your building and CBU bins first earlier than taking the plunge and upgrading the production container.
besides discontinuing help for i5/OS V5R3, the V5R3M0 edition of IBM’s iSeries access family unit will additionally lose help on April 30. iSeries access for home windows V5R3M0 (product id 5722XE1), iSeries entry for net V5R3M0 (product 5722XH2), and WebSphere Host access Transformation features constrained version V5 (HATS LE) will reach their conclusion of provider dates at the moment.
making ready for AnyNet’s Eventual demise
whereas we’re talking about discontinuing guide, be aware of IBM’s long-time period plan for AnyNet aid. AnyNet is IBM’s implementation of the Multiprotocol Transport Networking (MPTN) structure. It’s been round continually and in keeping with IBM, AnyNet is a “…family of products that permit purposes that are written for one classification of network protocol to run over a special category of protocol.” Most principally, AnyNet enables SNA-based functions to run over a TCP/IP community. it is at the moment supported on i5/OS V5R3 and V5R4, as well as on the i 6.1 operating system.
So what does the loss of life of this ancient dinosaur should do with equipment i and vigor i administrators? while AnyNet usage has declined in the i5/OS world, many groups still use it to connect older legacy gadget (corresponding to line printers and dumb terminals) to AS/400, iSeries, device i, and vigor i methods. which you can nevertheless discover AnyNet-primarily based controllers complicated at work in warehousing and other environments that use older line printers (comparable to an IBM 6400) to provide big quantities of select tickets, bills of lading, invoices, and different multi-kind printouts. These configurations can also be enabled via controllers that make use of AnyNet (as a substitute of twinax) as its underlying structure to attach older devices to i5/OS machines. My company nonetheless employs some AnyNet-primarily based solutions, and that i suspect that we’re no longer by myself within the system i/vigour i world.
And that’s where the difficulty is available in. As IBM rolls out extra vigour i machines, it has introduced that 6.1 will be the last unencumber to aid AnyNet. in keeping with huge Blue, the next i operating equipment unencumber may be the primary release devoid of AnyNet assist. considering the fact that AnyNet is supported through i 6.1, they will do the mathematics to check when the next liberate will arrive, and when AnyNet guide can be phased out.
considering 2001, IBM has consistently been releasing new working systems every two years. OS/400 V5R2 turned into launched in 2002, i5/OS V5R3 was released in 2004, V5R4 got here out in 2006, and that i 6.1 was released in 2008. This capacity the next working system version (let’s name it i 6.x) will theoretically be released in 2010. historically, this also ability that they are able to expect IBM to announce end of program aid for each of their working programs in two-yr increments, which may also happen in response to here time table.
The result of these calculations is 2-fold. For companies using AnyNet, they could likely improve and reside on working methods helping AnyNet via 2013. however, if you need to improve to the newest working gadget every time after 2010 and you’re running AnyNet, you’ll deserve to dump your AnyNet-based processing before which you can accomplish that.
for many corporations, AnyNet isn’t a factor. however, in case your enterprise has distinct facilities the usage of AnyNet-enabled IBM printers and dumb terminals to process orders, the clock has begun to tick. You may need to beginning phasing out AnyNet (and its compatible contraptions) as early as 2010. The different consideration is that if you would like capital to substitute AnyNet machine in 2010, you may need to delivery alternatives in 2009. here is as a result of most agencies require you to request finances funding in improve for the next fiscal year. So if you need device alternative funding in FY 2010, you could need to charge out the alternate options in FY 2009.
The morale here is that if your store has been relying on older AnyNet configurations, it can quickly be time to study an alternative.
what is a Paging choice, Anyway?
In my recent column on Tuning i5/OS Storage swimming pools for performance, I described the Paging choice cost for a storage pool the following manner:
you can exchange the Paging alternative price on each and every storage pool to define even if the pool is mounted (*fastened, the place it can not be modified via automatic performance tuning) or even if it's going to be described as a calculated storage pool (*CALC, the place efficiency tuning can instantly modify the pool size and exercise levels).
here is improper. IBM certified expert in AS/400 Technical solutions Ernie McCormack wrote in to straighten me out about Paging alternatives:
The paging alternative defines whether the system dynamically adjusts the paging features of the storage pool. Set a pool’s Paging option to *mounted, and the system doesn't regulate the paging features. Set it to *CALC and the device does the adjusting. environment a pool’s paging option to *CALC is also known as turning on knowledgeable Cache.
And Ernie is right. The Paging option container for a shared storage pool refers as to if IBM’s expert Cache feature is grew to become on for that storage pool. knowledgeable Cache is a collection of more desirable paging algorithms for databases and linked objects. amongst other things, it optimizes the block measurement for retrieving statistics, which allows for classes to cache greater records at one time.
The problem is that the definitions of paging options and expert cache are delicate and often complicated to explain. I’ve worked with paging alternate options in this column earlier than and i’ve even taken a whole column to explain how the *fixed and *CALC values work and what their relationship is to expert cache. For extra suggestions on these considerations, see this text on fixed storage swimming pools and the Work with Shared swimming pools (WRKSHRPOOL) command.
