What about the performance of MDM???

when I execute 8 matching strategys at the same time, at this time I will could not to do other thing,I almost can not get the response from mdm!

From What i have seen, yes, if you are performing matching on data manager and execute a query on portal the response either takes eternity or you get a locking exception.
in 7.1 the worst part was matching on tuple values which has improved over the hot fixes. I am working on mdm71 since start of ramp up.
What i can suggest is, when you run matching strategies, add some search filters to it. that will reduce your target records and would increase your performance on matching execution.
btw, we had the performance issue while running 1record against 40000 records and only 1 matching strategy, running 8....definately not something that some one should test performance on. I don't think anything would help:-). Though would strongly suggest to check the KPIs of performance on matching with SAP directly as there are no such KPI's available in documents.

Nitin

About the performance of using shared variables

Hi
My system has almost 200 I/O points,I want to the host communicates with PLC using OPC(I had create a OPC I/O Server).
If I use shared variables bind to OPC data items, there must be almost 200 shared variables.
And my puzzle is that what's the performance of using these shared variables,will they eat up memory and processor?
Another question is that if an shared variable will be time-lapse(i.e.,if an OPC data item value change feedback to program block with 0 delay or not),if so ,then how many millseconds it will delaies?

here is a paper about the performance of shared variables.

About the performance of plumtree portal.

Please let me ask a question about the performance of plumtree portal.The good reply is not obtained although I have asked the support center in Japan.I saw the log of ptspy.Delay had occurred in the following two points.
1. Although it is a "<.static.> InetHost::Select(xxxx) is called on 0 write+xx read sockets." part, what processing is performed actually in the message by the plum tree by the processing of inethost.cpp in a WebDownloaderParallel.dll component?
2. Although it is the part of "CreateFilterContext()-Created new context at address" by the message, is it the operation which is creating the context path for connection with the exterior in PTGWFilter.cpp in a Gateway component?
Moreover, although delay of processing may occur in these parts, what factor can be considered?
Thanks,

Hi, this is Nobuyuki, Plumtree PSO, working for this project.
I'm attaching snapshot of ptspy from them. I've found that there are two ares which
seem to take much time.

elimnate this bottle neck.

Is there any benchmarks about the performance of BI web Intelligence

Need to know any benchmarks about the performance of business objects web intelligence report against number of records stored in a relational database

There no as such benchmark. However you can verify the actual time take by report query when fired directly on DB and time taken by Report to execute. and if there is lots of difference, then those report would ideal for tuning.
e.g. if MOnthwise revenue report takes 5 mins and the actual query takes only 1.5 mins when fired directly on DB. that means something wrong with universe/reports.
I hope this help you to get started.
Please share your exp. its interesting to know.

Which Bag do you use for your Camera? What about the GadgetBag 300EG?

Which Bag do you use for your Camera? What about the GadgetBag 300EG?

I agree - it's all about preference. I use the ThinkTank Retrospective 7. I *love* ThinkTank's attention to detail... everything from having a rain cover included with the bag, to having ingenius use of velcro (sp?) patches to enable you to "silence" the bag so it doesn't make the big "SCRATCH" sound when opening the bag during a quiet event, etc.
My best advice would be to do your research (which you're clearly doing) and have a clear understanding of the return policy wherever you buy it, and then don't be afraid to return it if you get it and feel it doesn't meet your needs. A restocking fee is a small price to pay to not be stuck with a bag that doesn't work for you. And if for any reason you get it and can't return it, there's always eBay.

Best pratices for the customizing about the performance

Hello,
I would like to know the list of the best pratices for the customizing BPC NW 7.5 about the performance.
Best regards
Bastien

Hi,
There are few how to guides on SDN which will give you a basic idea on script logic. Apart from this, you can refer to the help guide on help. sap.com.
The templates might also effect the performance. The number of EVDRE functions, the number of expansion dimensions, the number of members on which expansion takes place will effect the performance. A complex formatting in the template will also effect.
Hope this helps.

i want to produce wedding dvds.whats the best software to use...final cut x I'm thinking but what about the quality of the dvd? Can i use idvd?

The only Programms I worked with are DVD Studio Pro and iDVD. You can burn a Video-DVD with Toast but there is no real option to design your Menu. Just a few themes as far as I discovered.
Do you have a Blue Ray Device to burn* the HD-DVD? Are the Bride and Groom able to watch the Blue Ray?
* which is only possible with DVD Studio Pro and not iMovie as far as I know.
This might help
For better quality I would go the Compressor & DVD Studio Pro workflow I just learned.
Export the Movie as is from Final Cut Pro and then use Compressor to encode the File.
Consider delivering the Movie in a different way like a private video on vimeo, a Website or on an SD card which is not really romantic...

Read the article you linked
iTunes Store: Movie rental frequently asked questions (FAQ)
How long do I have to watch a rented movie?
You have 30 days from the time of rental to watch your movie, and 24 hours (in the US) or 48 hours (elsewhere) after you've started viewing to finish it. Once the rental period expires, the movie will disappear from your iTunes library."

HT1338 what about the problems with the trojan virus is that a problem for my mac as well?

What about the problems with the Trojan virus will this be a problem also for me using Mac

What Trojan?
If you're referring to the DNS Changer Trojan, it's highly unlikely you're affected. The actual distribution of the trojan was stopped several years ago and the perpertrators jailed.
The FBI has been maintaining the servers used by the trojan for the last 5 years in order to give affected systems time to be purged. They will finally shut them down on Monday.
Ensure that your router and the Mac's network settings are set for the DNS addresses of your ISP, or if you're not sure what they should be, change them to Open DNS using the IP addresses;

BBM Across Platform, what about the older devices?

Yes, as we all heard is that bbm is coming to android and Iphone. We all know that BB10 does not us BIS and the older devicec need BIS to operate to the full, why can blackberry not open this to all so that i can bbm without BIS on my older device? yesBIS is nice but what about the people that want to use their older phones like the BB10.
Only some features work without BIS, like the excample whatsapp, browser but all the good stuff like Blackberry world are blocked as well as Blackberry Protect, Facebook and so i can go on ....
Let the people that want BIS get it like that and the other that want it without BIS get it like that then Blackberre will be more flexible.
Cant they see they will now loose more customers to the other platforms where they can keep the people on the older native devices ....Please Blackberry UNBLOCK US ....

Yes, 1.19GB of "other" is normal. Normal is a little over 1GB.

I have to reinstall WIN 7 Pro on my PC, what about the CC app's? Can I reinstall them later again?

I have to reinstall WIN 7 Pro on my PC, what about the CC app's? Can I reinstall them later again?

The CC has been activated twice on 26th April &28th April 2014. You need to deactivate it first from any of the CC installed .
(Activation & Deactivation Help)
The other option is to deactivate it while installing for the third time. this will deactivate CC from both the earlier installed machines(I understand, it is being reinstalled on one of machine which had CC).
To reactivate it on the one of the previous machine, you need to launch any product, there shall be a prompt
, in that prompt there will be an option to " license the software", please click on that & sign in.
It will reactivate the CC on the first machine.

Mifi 4510L Mifi Hotspot...is it the network? and what about the firmware update?

I have spent several months trying to seek a solution on the repeated and frequent disconnects from the Verizon wireless network using my Mifi 4510 L. No success. I have conversed with Verizon Wireless "experts" on this matter and have basically been ignored, since they do not have a solution. It has cost me a pretty penny in wireless costs due to lost connections in downloads, etc...for which I do not get any credit from Verizon on my wireless bill...go figure.
I have even been accused by Verizon that the problem is my computer and hardware, even though I have ran several hardware, software, and "real-life" connection checks on other wireless networks with no issues at all. I even have been getting better connectivity when I use my Verizon USB UML290...but I hate having to switch moving my SIM card from the USB Modem to the MIfi4510L...one of these days the SIM card will fail. Verizon has checked the signal strength at my home and work locations (which I already knew as good), but never heard back from them.
Anyway, I have verified that my wireless network adapter works just fine on other wireless networks (no dropouts, etc). I have even upgraded to another Windows Operating System - Windows 7...which is more superior than Vista in dealing with wireless communications. I have implemented quite a number of the solutions provided by other great Verizon Wireless Community members, but the connectivity problems continue to occur.
When I did a review of my wireless hardware logs, I noticed that when I was encountering problems, the dynamically assigned address given to me on the Verizon Wireless network changed quite a bit, even when I was using the same web site. When my wireless connection worked fine, the dynamically assigned address was consistent. This seemed to change when I encounter peak network load times.
I would appreciate a straight answer from Verizon Wireless on what is going on with the network. I live in a solid 3G coverage area...but just far away from 4G to benefit for the increased throughput. The closest 4G location footprint is about 40 miles away from me.
Finally, what about the Mifi 4510 L firmware update? I have yet to see any notification about this firmware update, either through normal e-mail channels or even through my Mifi configuration site
http://192.168.1.1/mifi.cgi
What gives?
I realize that I am sounding a little perturbed about this matter, but it has been almost 4 months now...and Verizon is not living up to their part of the bargain on providing good tech support on the Mifi 4510L. When they do not have an answer...they ignore the customer. Not good business!!!

The firmware update was released a few weeks ago and there were multiple threads in this forum for it:
Software Update: Verizon Wireless 4G LTE Mobile Hotspot MiFi™ 4510L
The firmware update primarily addresses a problem with the MiFi switching from 3G to 4G and back. I would not expect it to resolve a connection issue for anyone in a 3G only area. Work through the firmware update instructions included in the link above and see if it helps.
There were no email notifications but the MiFi should have been redirecting you to the MiFi homepage every time you tried to browse the internet. The firmware update is mandatory so if you have not already completed the update then there might be something wrong with your device.
