Semantic and Logical partions

Hi All,
Please can someone help me to understand what are the advantages of Semantic partinitioning of BW 7.3 over Logical partioning of BI 7.0
thanks

That is a good question. A semantically partitioned cube is not the same as a multiprovider, and the table RRKMULTIPROVHINT is specifically designer for MultiProviders so my initial thoughts are that it is not required to maintain this.
However, there are many similarities between a MP and a partitioned cube, and you want to make sure that at runtime only the relevant partitions are accessed.
I would expect that SAP automatically provide DB Hints based on the definition of the partitioning. The reason why this does not happen with MultiProviders is that it is hard to automatically 'predict' which characteristics are used for partitioning. In the semantic partitioned cube, this is defined in the system so SAP should take this into account at execution time.

Physical and Logical Partioning

Hi Friends,
I would like to know what is the difference between these 2 types of partioning?? Is there any OSS notes to gain knowledge on this??
thanks,

to check number of partition, use table RSDCUBE field PARTVL_FROM,PARTVL_TO,PARTMAXCNT
hope this helps.

Logical Partioning doubts

Hi gurus,
Logical partioning is used to create additional cubes to load yearly data.
My small questions are
1) In the process chain after one year infopackage will be same with delta update type and cube name will change is it right ?
2) This will be done on first day of new year I mean first delta will be loaded of the new year like 2008 with the same process chain but different into cube name .
3) Old cube name wll be there till it loads last delta of year last day ?
4) If report is only for single year all data and I have 4 cubes with quarterly data for that single year under a multiprovider .will the performance come down ?
Thankyou gurus.

Hi George:
1) That is possible. see also under 2
2) You can also create a filter in the update rules. Add you new cube to the info package and filter the records in the update rules (start routine, delete from info package where date = etc.) In this case you can implement the new cube some weeks before the new year and remove the old cube after a few weeks (at the moment you are sure no records of the previous year are changed)
3) then you can also remove the old cube from the info package and remove the update rules.
4) We implemented queries about single year data on the cubes directly (easy to copy as the cube are equal and then renaming the query with yaer in the name) and queries over more than one year on the mutli cube. (actually we made two mutlicubes (1 with current and last year and 1 with all the years)

Logical Partioning

Hello Experts,
Can someone let me know the procedure of logical partioning a cube. I am actually designing a cube for each year and i would want to know the whole process ( the configuration in BW including ).
All answers would be duly rewarded.
Thanks,
Nandita

Hi Nandita,
Well, u really need not to have separate the cube for the Yearly basis. U have store data for several years in the same Cube. Well Logical partitioning is dividing the data on the TimeScale, The Permitted time Scale is either CALMONTH or FISCPER (fiscal period) (Only one is possible, not both), Here there will be individual tables at the database for timescale.
U can follow the path Cube-Extra-partitioning- select your timescale- and the range.
Here no of table created will ne range+2, two for Before and after range.
This Database partitioning is based on underlying database, Not all database Support this, MS SQL do not support database partitioning whereas Oracle Supports.
While creating this database partitioning cube should not contain any data.
This all is information pertaing the database partitioning.
Assign the points if it helps You.

Merge physical and logical partitions

How do I extend my physical arch partition with an unallocated space logical partition?
I want to add an unallocated space logical partition to a physical partition
or better said I want to grow my existing arch physical partition with the unallocated space logical partition.
Last edited by karlzt (2010-03-20 15:50:31)

It is not that easy. You can resize and/or move either physical partitions or locical partitions inside the space of the (physical) "extended partition". But you cannot simply take space from a logical partion and assign it to a physical partition adjacent to the extended partition it is part of. Which means you can extend a physical partion only from free space which you can produce by a prior shrinking/moving another adjacent physical partition.
The problem is, I currently know of no way to shrink an extended partition without losing some of the enclosed logical partition data (or even all logical partions at once). One could try, as a proper backup is advisable in any case before messing around with partitions.

Logical Switch and Logical Network

Hello All...................I have Hyper-V Failover Cluster based on 5 Hosts and I am managing it with VMM 2012 R2. I was slightly confused with respect to Logical Network and Logical Switch in the Fabric Settings. I would appreciate if someone could
shed a little light on the difference between them. Also, while there is a Logical Network defined by default (Name of the Virtual Switch of Hosts), there is nothing defined in the Logical Switch. Which one is mandatory? Logical Network or Logical
Switch? Can I delete the default Logical Network?

Hi Nick,
Please find below link for the whitepaper mentioned by Kristian.
https://gallery.technet.microsoft.com/Hybrid-Cloud-with-NVGRE-aa6e1e9a
For a complete reference please refer below series. This covers VMM 2012 SP1 but should be fine with R2 as well.
http://blogs.technet.com/b/scvmm/archive/2013/01/08/virtual-networking-in-vmm-2012-sp1.aspx
Logical Network is defined for easier management and used in Network Virtualization where as Logical switch is used to configure networking in multiple Hosts rather than creating individual Virtual switches in each host. If it were me I'll leave the
default logical network as there is no harm of doing nothing in it.
I hope this will shed some light into your situation.
Thanks,
Janaka

Problems with Presonus Firestudio and Logic

I am having problems with compatability with my brand new Presonus Firestudio recording interface and Logic pro 8. I am new to logic but not to home recording, and i cant understand what might be the problem. When i use the firestudio with garageband it works easily. In the garageband sound preferences there are input AND output channels that the user can define. (i.e. you can set your input channels to come from the firestudio while the output channels go to the computer speakers or headphone jacks or whatever you define it as).
From what i have seen in logic, there is only one option for your audio settings. when in preferences and under audio, there is a "device" setting in which you can define your audio device. Wheather this is input AND output for the program, i do not know. but the problem i am experiencing is that whenever i choose the firepod as the input device, no sound from logic will play from the speakers whatsoever. My first thought was that maybe ouput was going straight to the firestudio, but after plugging headphones into it this also did not work. Has anyone had success getting their firestudio to work in logic? if so let me know what settings you had to use, and how you got to moniter your input from from the firestudio via your computer.
p.s.
another WIERD problem i have run into, is that if i shut off the firestudio while logic is open, alot of times it will shut down my whole computer. i have never heard of this happening. what am i doing wrong?
thanks!

ah, I was hoping to find my solution here, but alas the thread is gone...
I recently bought a Macbook running Leopard, and am having difficulties with my PreSonus Firestudio Project thru Logic and Mainstage. I can get audio input and output just fine, but there's a ton of distortion/crackle. Kickstarting the sample rate seems to clear it up for a minute or two, but then the crackle comes back. The recorded tracks sound clean if I unplug the Firestudio, so apparently it's only in the monitoring stage?
On the PreSonus board, they're claiming it's Apple who needs to update drivers for Leopard; PreSonus says the "Firestudio Project is Leopard compatible."

I have a Power Mac G4 double mirrored model and everytime I shut it off it will not go on when I hit the power on/off button again. However, if I unplug and plug in the power cord it boots fine and everything is OK. The PMU and logic board have been reset. Sometimes my Mac goes on just by pressing the power on button but most times I have to pull the power cord and put it back in. Any ideas or help out there for this? Could it be a failing power supply? Apple Care says that this model is obsolete so there is no help from there. John

Hi John,
That's often a sign of a bsad Capacitor in the Power Supply, but...
Might be time to replace the PRAM Battery, 4 years is close to their lifespan, far less if ever without AC power, & can cause strange startup problems...

Best Interface for GarageBand and Logic?

I have been using GB and Logic Pro extensively for the past 2 years. I would now like to know what the best interface would be to use in order to use 8 mics at one time. Thanks for your help.

Only around six grand....but if you want da best...this is certainly in that stratosphere...

Hard drive crashed and had to replace drive and logic board on my MacBook pro. After Install tried to sync with my iPhone and a dialog box pops up stating "this iPhone synced with another iTunes library, erase and sync?". I checked the manually manage music and videos box because I don't want all my wife's pics and music on my iPhone. How do I Sync without erasing what I have on my iPhone???

It's not crap at all.
It's not that simple. For example, I've 3500 songs on my MacBook but don't want them all on my phone, so I have to manually select each song again???
There has to be a solution.
Why not simply make a playlist with the songs you want on the iPhone?
and maintain a current backup of your computer.

My computer has been seen at Genius bar 6 times for freezing up, reloaded all original settings and even went to the apple shop where they replaced the battery and logic board. Still freezes after I try to reload iTunes stuff and app stuff from apple

my computer has been seen at Genius bar 6 times for freezing up, reloaded all original settings, all of their diagnostics, and they even sent it to the apple shop where they replaced the battery and logic board. Still freezes after I try to reload iTunes stuff and app stuff from apple, especially iPhoto which is seems to refuse to load and then begins freezing up all over again. Anyone else have this problem. Other than this, I have had absolutely no problems with this computer. Now, it's a file of junk.

Hi Ronald ...
Have you checked lately to see how much free space there is on the disk? Especially since iPhoto freezes at launch ...
Click your Apple menu icon top left in your screen. From the drop down menu click About This Mac > More Info > Storage
Make sure there's at least 15% free disk space.
And make sure the OS X software is up to date.
Click the Apple  top left in your screen.
From the drop down menu click: Software Update
If you have anti virus software installed or are using third party Mac cleaning utiliites, that may be part and parcel of the your problems.

RFC and Logical System names

Hello......is it necessary to have RFC and Logical system name for the connected system to be identical?Is there any explanation behind this if thats true....

Hi Gaurav,
It is recommended, but not mandatory, right, Muthuraman?
The system uses some transactions to determine which RFC will be used for the communication between one system and another, for example, in transaction 'Define backend systems' in SPRO, you can define that the current SRM client has an ECC backend system named X and the RFC destination for this X system is Y (not necessarily the same name).

RFC Destination and Logical System

Hi Friends,
Can anybody tell me how the RFC Destination and Logical System are related to each other?

Hi,
In any ALE scenario u need one sender and one receiver system.
Logical systems are just logical representation of these systems but in case of RFC destination u specify technical parameters for those systems like IP address and username and password to connect to that system.
Thus when u create port i.e.we21 u specify actual RFC destination for the system to which u want to connect and when u create partner profile for that logical system u specify this port so when u want to send data to this logical system i.e receiver system port will be used which in turn has RFC destination which will be used to connect to that system.
In simple terms logical systems are logical representation of any system and RFC destinations are physical/techinical systems.
Thanks.

Diffebetween Business system and Logical system...

what is the difference between Business system and Logical system...

Hi
Business system is a logical layer needed for configuration in integration directory. On the other site technical system is physical representation of your technical landscape. In case of SAP technical systems you can have more than one business system relation. In that situation there is relation one client to one business system.
If your technical system changes, then you definitely need to point this new technical system to the existing Business system which has been used to do all the Configurations in the Integration Builder.
