That's a nice little change introduced in FP6...

TM1 10.2.2 Fix Pack 6 - Using multi-threaded query to execute a view as a TurboIntegrator data source
IBM Support wrote:
Abstract

As of TM1 10.2.2 Fix Pack 6 (FP6), multi-threaded query (MTQ) is used by default to execute a view extract that is the data source for a TurboIntegrator process.

Content

In previous versions of TM1, you had to execute a ViewConstruct in TurboIntegrator (sometimes in an entirely separate process) to take advantage of MTQ when a cube view was the TurboIntegrator data source.

As of TM1 10.2.2 FP6, this is no longer the case. By default, MTQ is used directly on the execution of a cube view data source, provided the following conditions are met:

1. The MTQ parameter must be enabled in Tm1s.cfg and set to a value of 2 or greater. By default, this parameter is not enabled in the Tm1s.cfg file for TM1 10.2.2 FP6 For details on the MTQ parameter, see http://www.ibm.com/support/knowledgecen ... t_mtq.html.

2. When defining the view extract for the TurboIntegrator data source, the Skip Consolidated Values option must be disabled and the Skip Zero/Blank Values must be enabled.

If you do not want to use MTQ when executing a view data source, you can disable MTQ in the TurboIntegrator process by adding the following function to the Prolog of the process:

DisableMTQViewConstruct( );

This function must appear in the Prolog procedure, it has no effect in any other procedure within a process.
I also like the new TI function CubeDimensionCountGet and others might like the fact that TM1RunTI can now execute chores.

This FP6 seems like a premature e-publication to me :-)
Regarding the MTQ usage I'm wondering how much benefit this bring if you have to include consolidated values in the view extract...

If you set the view up so that you don't have any consolidations in the view definition to start with (why have them there if you are only going to skip them anyway?) then there need not be any extra work being done. Also, once you have done the ViewConstruct and the view is cached, then you can apply SkipConsols further down the Prolog if you still need to.

As for the speed improvements, and with a list of caveats that IBM would be proud of, such as whether the system is idle enough to be able to fully utilise the full number of cores that the MTQ setting allows, the slight overhead of splitting the threads up and combining them again, and possible re-work done on the MTQ threads if there are complex rules on the cube, etc. etc. then you should see a fairly linear improvement in the amount of time the TI takes to evaluate the data source view.

As an example, with MTQ at 7, I'm getting a TI that used to take 120 seconds now taking 20.

If you're not seeing the improvement that you expect, add the stargate loggers to the tm1s-log.properties and check that you are getting all the values that you expect in the stargate definition and adjust the layout of the source view if necessary. Also check that VMM is set to an appropriate value.

Hi Andy,

Creating a view extract using ViewConstruct was already possible before FP6. If you still need to go this way after FP6, than this new feature does not bring much new in my opinion. Indeed you can leverage this feature by only selecting leaf elements on the various dimensions, but the nice thing of the Skip Consolidations feature is that it saves you from quite some coding (which is one of the things that makes TM1 to be considered a technical/IT tool).

This. There would be no benefit of MTQ if there are no consolidations to be performed.

The change introduced by FP6 is that there is no longer the need to do a ViewConstruct in Prolog. MTQ will kick in automatically if the source view contains consolidations and is zero-suppressed.

Apologies, the links worked yesterday, but this seems to be a case of someone in IBM pressing the 'publish documentation' button too quickly and then retracting it. I'm hoping the links will work again in a few days.

CubeDimensionCountGet( CubeName ) returns the number of dimensions in a cube, something that up until now was only possible via workarounds like WHILE loop + TABDIM combination.

My colleagues went to the Vision session where this was stated by IBM - but we did do some testing when MTQ first came out with a very large, rule based model and achieved a speedup factor of x3 on ruled content at base level. This may no longer be the case for newer releases but I'd be surprised if that were to be the case.

You're absolutely right, MTQ also works for rules (albeit not providing the same performance increase as for natural consolidations). What I meant to say (and probably should have phrased it better) is that MTQ will not increase performance if there is nothing to calculate because the view only contains leaf-level values.

Indeed it was, and that was what I was describing.

Yes it's not going to help in every situation, but if you are relying on SkipConsols to, well, Skip Consols, but your view contains rules such that it would still benefit from MTQ, then it could be time to do that extra coding... and that is, of course, assuming that the manual ViewConstruct and SkipConsols will still work with the new behaviour of FP6. And given that FP6 seems to have disappeared into the black hole of Fix-Packs-that-were-not-quite-as-ready-to-release-as-IBM-thought, we'll just have to wait and see.

The performance improvement that I mentioned was on a view that contained a mix of rules and a few required consolidations.

Being able to use temporary views and subsets as source is a good fix.
Graphs in TM1Web are still buggy though..

Looking at the fix list I think they only fixed the temporary subsets issue. We still can't use temporary views as data source. If they fixed that too that would be really awesome. I actually asked IBM support about it back then and was told these 2 issues will not be fixed until 10.3...

I don't see it in the FP5 fix list, but I'm pretty sure you can use temporary views as a data source in FP5.

Are you saying that you have tried them in FP6 and they don't work?

Using temporary views as a datasource was fixed in one of the early FP4 IFs, so even if you didn't get that particular IF, it should have been an early enough fix to have been included in FP5, and you would hope FP6 as well.

I've got systems running on FP4 IF15 and IF19 currently, and temporary views as a datasource work, temporary subsets don't.

I haven't installed FP6 yet. I thought the release notes were up again but not the actual downloads.

I tried temporary views/subsets when they were introduced in FP4 last year. At the time they didn't work. I am running FP5 right now and I didn't know the temporary view issue was already fixed. Last year I was working on a TM1 application that could really use both features. Since they didn't work at the time I went with the usual create/delete method instead. I didn't look at this again until I read the FP6 fixes.

I will give them a try again with FP6 and report back. I'll be working on v2.0 of that application later this year. This will be a great opportunity to make good use of them.

All,

After installing the fix pack 6 you will face difficulty to access tm1 architect.
Please read the fix pack release notes and make correction in cognos configuration and .cfg files respectively.

All,
on my opinion the FP6 includes now a mojor bug letting crash the server. This is related to the Architect and TI.
Preconditions:
- use function "Export as text data" for a cube (in cube context menu)
- the data set as a result of selected N- and/or C- elements will be empty
- the option "Skip Consolidated Values" is not checked
==> Click "Export" and "Save" and the TM1 Service is gone.

The same thing will happen if you run this in a TI, using the an "empty" View as a datasource and set: ViewExtractSkipCalcsSet (sCubeName, sViewName, 1);
You can check this out by yourself, simply using the SData sample database in local server mode. E.g. try to export the an empty PriceCube view.
The chrash does not depend on used MTQ settings in tm1s.cfg. You can use it or not.

I found a workaround for Turbo Integrator (TI) processes:
- use the new function DisableMTQViewConstruct() in the Prolog if you use a view as a datasource:

Because of this bug it seams to me sensles to use MTQ at this time (after installed FP6).

Best regards,
Olaf

That's probably going too far. Thanks for bringing this defect to our attention - it's a good thing to know. But considering that it is possible to check in the Prolog if your source view will return at least one value, I would rather add a bit of code to do just that and prevent the crash from happening than throw the baby out with the bathwater and not use MTQ entirely. In many applications these days MTQ has become more than just a nice-to-have.
