I have a sql server 2008. What is the best placement for the tempdb.mdf?
The sql server has three drives c, d and e. The c drive contains the program. The D drive contains the main db and the tempdb.mdf. The E drives contains all the logs. I've seen the disk queue for drive D spiked up to 50 sometimes. The majority of the read/writes
came from maindb and the tempdb. I was wondering if it is a good idea to separate the tempdb from the maindb to another drive? Thanks.

Hello,
Disk queue value you posted does not qualifies exactly which counter you are talking about.If you are getting instantaneous high value for Avg disk queue length it is not a issue but if this queue length is for long time and continues to be a straight line
then it can be issue.Its always good practice to put tempdb on separate drive to gain performance.Please post the value which counter shows not the value shown by graph.Refer below link

The best place for content server
Hello,
We need to install content Server . SAP ECC is in Paris .
The users who will use the content server will be in New-York.
Is the best place for content server in Paris or in New-York?
The question could be : Will a document (for ex. a pdf of 100 Mb) to be checked_in the CS be first transferred from frontend to ECC and then from ECC to CS or directly from frontend to content server ?
ThanksHi Oda,
If your users are in New-York, then better to have content server there to optimize network traffic and speed. There is something called as distributed content server concept where you can have different storage areas for different geographical locations.
And as far as i know, whenever files are checked-in, they are directly stored in content server and it will not route through the ECC. Only DIR stored in the ECC will be linked to the file in the content server.
Hope this helps.

What is the best microphone for the MacBook
What is the best microphone for the MacBook
What do you plan to use this microphone for? By "best" do you mean best sound quality? Best price?

What's the best cover for the new iPad (3rd generation). I've been told by a store employee (university bookstore) that there are problems with the magnetic covers on the newest iPad. Suggestions?
The best cover is the one that suites your needs. Try Google. There are dozens on the market.
As for the Apple Smart Cover, it does work with the new iPad. There are a few reported issues with it, but that doesn't come close to representing the totality of folks with it. -
my daughter is a college student. she needs to write and compile c programs on her mac for a class this semester. what is the best place for her to start to get the correct compiler etc. to use ? thanks
If you know that you will not be asked to design GUI interfaces, and the C programming course will adhere to command line compilation environments, then get the Xcode command-line developer tools, and skip the extra complication of Xcode until you absolutely need it. Apple has kicked GNU C to the curb and is rightly so, using Clang/LLVM compiler technology.
Sign up for a free Apple Developer account using your Apple ID, and then visit the Mac Dev Center, and towards the bottom of the page, you will see additional downloads. Click on the associated, all down loads link. Know your OS X version beforehand, as the command-line tool releases are tied to general operating system versions, and the most recent Xcode version. That said, there are currently two March 9, 2015 command-line tools for Xcode 6.2 — one for OS X 10.9 Mavericks, and the other for OS X Yosemite. -
Guys, good evening!
What is the most recently (or the best) iOS for the iphone 3G?
Nowadays, I'm using the 4.2.1, but I'm having some problems to install apps from Apple Store because this iOS is not compatible with the apps.
Thank you very much...Thank You Niel!
And if I install another version (eg 4.3), can I damage my iphone?
This is the version required by the Apple Store when I try to install apps.
For you understand better my problem, I'm not able to install simple apps like facebook and skype
What do you advise me to do?

What are the best practices for the RCU's schemas
Hi,
I was wondering if there is some best practices about the RCU's schemas created with BIEE.
I already have discoverer (and application server), so I have a metadata repository for the Application Server. I will upgrade Discoverer 10g to 11, so I will create new schema with RCU in my metada repository (MR) of the Application Server. I'm wondering if I can put the BIEE's RCU schemas in the same database.
Basically,
1. is there a standard for the PREFIX ?
2. If I have multiple components of Fusion in the same Database, I will have multiples PREFIX_MDS schema ? Can they have the same PREFIX ? Or They all need to have a different prefix ?
For exemple: DISCO_MDS and BIEE_MDS or I can have DEV_MDS and this schema is valid for both Discoverer and BIEE.
Thank you !What are the best practices for exception handling in n-tier applications?
The application is a fat client based on MVVM pattern with
.NET framework.
That would be to catch all exceptions at a single point in the n-tier solution, log it and create user friendly messages displayed to the user. -
SQL Server 2008 R2 - Connection from multiple sources makes the database drop.
Hey,
I have a database being accesses from multiple sources - IIS and WPF application.

The problem being solved once I restart the IIS service or the SQL instance service.

What is the best upgrade for the new Air?
I am looking for a new Macbook Air for college and was wondering what upgrade would be the smartest decision. I was thinking of a 13" air with:
1.7GHz Dual-Core Intel Core i7, Turbo Boost up to 3.3GHz
8GB 1600MHz LPDDR3 SDRAM
128GB PCIe-based Flash Storage
or a 13" Air with:
1.4GHz dual-core Intel Core i5 processor
Turbo Boost up to 2.7GHz
8 GB memory
256GB PCIe-based flash storage1
The former option would save me approximately $60. What are the benefits of an upgraded processor? I have heard they would make my computer overheat more easily and the fan would be significantly louder. This is making me question if the processor is worth it. In addition, I am unsure of how beneficial the 8GB as opposed to 4GB of RAM would be. How can I optimize the speed of my laptop if I want to run Windows through Parallels? That is essential.
Please advise, Thanks.If you buy a 2013 model you can save up to $400+ from online resellers who are clearing out the "old" model.
However the "old" model is nearly 100% identical in performance .
to answer your question, unless you plan on gaming or video editing, get the I5 with 8GB of RAM with 256 SSD -

What is the best battery for the magic mouse? I replace every month
What is the best batteries to use with the Magic Mouse? I am changing mine every month, I purchased the IMAC in April this year.
Good choice...even if that do not last as long as Apple claims (like any batteris DO ) you have a set charged and ready to go...no trip to the store for batteries at 2:00 AM. And far be it for me to advocate doing thie, any rechargeable batteries of the same specs will work with the Apple charger...they don't have to be the shiney silver batteries

What is the the best app for the x?
just got the droidx and want to know in your opinion what the best app or apps are and please explain what the do. and what are the must have apps for the phone as far as getting the most out of my device?
I don't have my phone with me now,so have to think of the apps off my head.
aTrackdog= Uninstall apps & also you can see the top 100 most popular apps in the market
Basketball shot= Fun fun basketball game. You just shoot basketballs into a net while being timed
Labyrinth 3D= It's a 3d board game with a marble. You have to avoid the holes & make it to the end spot
Carrom3D= Another game,but it's a pool game. You can play with your friends, by yourself or other android users
Where's My Droid= If you put your phone on silent & need to find it, you can just text your phone with the secret word.It'll ring with this app!
SMS Backup= Saves your text messages to your sd card
1001 cocktails= Alcoholic drink recepies available
HI AIM= I like this app because it uses data as instant messaging instead of it counting towards your text messages
HandcentSMS= The most popular messaging app. It has more feautes to offer (change front,change color,change buble color...etc)
Ringdroid= Create ringtones. Either record ringtones or make ringtones out of the songs in your phone
Ringo Lite= Apply ringtones to text messages or calling ringtones (can be applied to contacts too)
The most "needed" apps I would say get would be where's my droid, sms back up, hi aim, handcent sms and ringdroid -

What is the best case for the Dinc???
I'm looking for a case for my Dinc that i get in 1 week, but I was wondering what everyones favorite case is. Also has anyone seen or used the pdair aluminum case. It looks very nice but I was wondering how well it works/ feels/ looks.
Thank YouI origianlly got the fade to black gradient case (hard plastic snap-on case black at the top and gradually changes to red on the bottom and from verion) and I still have it. But after taking it on and off quite a bit I got the feeling that I'd end up breaking the snaps, so I picked up the black Verizon silicon case, and I love it. It absorbs a drop better, it stretches slightly when putting it on, and to me looks almost like it is part of the phone. It bulks up the phone less than the snap-on case I was using, it gives better grip in the hand but it doesn't going in and out of pockets. The snap-on case I believe went for $20-25, while the silicons go for $15. Hope that helps.
P.S. I use a holster (case logic from WalMart) which has felt on the inside and the silicon works fine in and out of that as well.
Maybe you are looking for
