Will Antivirus bring down the performance of SAP System

I have installed SAP Netweaver in my PC.
During my installation of SAP Netweaver, it insisted to disable the McAfee Antivirus running in my machine to continue.
Also I observed running the SAP Netweaver installation with McAfee Antvirus slowing down the performance.
Hence,
1.Can anyone suggest is it advisable to run Antivirus in the machine that contains SAP softwares?
2.Will there be any impact in performance due to Antivirus running in SAP software machine etc.
3.If Antivirus can run on the SAP software machine, Do we need to include any parameters to not to SCAN SAP supporting software files?
4.Is there any specific antivirus can be used in a SAP Software machine?
Please suggest.

Hi Vinod,
1.Can anyone suggest is it advisable to run Antivirus in the machine that contains SAP softwares?
Yes, it advisable run antivirus.
2.Will there be any impact in performance due to Antivirus running in SAP software machine etc.
Yes, There is impact running antivirus. By default antivirus will scan all the folders and files.
3.If Antivirus can run on the SAP software machine, Do we need to include any parameters to not to SCAN SAP supporting software files?
Yes, There is way to exclude the scanning of the folders where SAP software is installed.
Names of the folders need to excluded in windows operating system are
1. USR folder
2. Excluding Data base files are not recommeded, but if necessary you can exclude.
Maxdb Database
sapdb folder
MS SQL 2000/2005
>Program Files\Microsoft SQL Server\MSSQL\Data\xxxDATA1.mdf -->Particular Database file in MS SQL 2000.Here xxx is your instance name.
>Program Files\Microsoft SQL Server\MSSQL\Data\xxxLOG1.ldf --> Particular log file in MS SQL 2000.Here xxx is your instance name
>Program Files\Microsoft SQL Server\MSSQL.1\MSSQL\Data\xxxDATA1.mdf --Particular Database file in MS SQL 2005.Here xxx is your instance name.
>Program Files\Microsoft SQL Server\MSSQL.1\MSSQL\Data\xxxLOG1.ldf --Particular log file in MS SQL 2005.Here xxx is your instance name.
3.
Program Files\sapinst_instdir folder
Steps given below to exclude the SAP folders in McAfee antivirus Ver 8.0.0 and above. May be applicable for older version of McAfee, if the interface is same as

I'm about to buy a 27" i-Mac. I would like to connect my 30" Cinema Display to it as a second monitor. What will I need to do that? Will this slow down the overal performance?

The new iMacs do not come with a MiniDisplayPort, they have Thunderbolt, so unless you are talking about purchasing one of the previous generation iMacs such as this refurbished model in the online Apple store, it won't work. And yes, if you are going to get the full range of video resolutions you will need the Dual-Link version.
For details see the store's web page on the Dual-Link display adapter.

How to upload files in cluster without bringing down the cluster.

Hi,
Here is my problem:
My weblogic portal 7.0 application should run in 24x7 environment. The production
system is running in a cluster mode with external staging. Both the managed servers
are pointing to the same application sync database.
So to give a solution to this problem, we are trying to bring down one managed
server down and apply the patches into that managed server without bringing down
the other. Since webflow files and entitlements needs to be synchronized with
the portal database. If we perform a sync on the portal database, there might
be a chance that it might corrupt the existing portal database state. Our deployment
would not be complete unless we perform a sync on the other managed servers. So
we could not able to update the latest pathces into the cluster without bringing
down the cluster.
What I would like to know is "Is there any work around to get rid of this problem?".
I would be delighted if any one provides the solution.
Thanks & Regards,
Ratnakar

Hi Ratnakar,
When you perform sync you do it against the admin server which in turn does it
to the managed server. If you want to apply any changes to webflow you can do
it on the live system itself. I mean apply the new webflow and entitlements and
do the sync on the live system. Also while doing sync there are two modes. One
mode will sync only the modified changes and the other will apply all of it. You
can opt for the first option by which you can sync only the modified changes.
This may bring a small disturbance but it will be unnoticed.
The other option is to have two separate domains(each having one admin & one or
more managed servers) which may be having two separate portal databases. In this
way you can apply patches to one domain while other domain may provide the service.

B520 - how to bring down the monitor contrast?

Brightness control in the front panel are not enough.
the backlight is too much for me to handle
Does anyone know how to bring down the contrast even more?
thank you.

I'll clear this up a little...
NVIDIA Controls does not have any control over the lamp / backlight on the screen. You can turn down
the gamma / brightness / contrast, and you may think you see it darker.
YEEEEEEES. it's dark but the intensity of the backlight is still there. You can feel it from miles away.
I chose Lenovo over ASUS just because of the GT555 option, and it was the worst mistake ever.
Asus Et2700 series do have Contrast/Brightness controls for the screen in Values from 0-100.
You can turn the screen completely dark if you want. Asus have never let me down, but thanks to my greed
always wanting more, thought i would never feel complete unless i had the gt555.
This is what happens when you fall for the marketing agenda.
Fortunately, i sold it already. And this would be the last time i'll purchase something from lenovo.
I'd like to think this is something that they just never thought. WRONG!!!. They know. they do it on purpose.
That's their way to make you feel incomplete, so you can start chasing for something else and fall again
in the marketing agenda.
There's always a way to make an "ALMOST PERFECT" product, the worst nightmare for you.
they have done this for years, since the beginning of times.
Let's not forget about the SATA performance issue in H67/P67 chipsets:
http://www.pcstats.com/articleview.cfm?articleID=2589
the B520 is one of the lines affected and lenovo did nothing about it.
And please let's not forget about the Trojan that got infiltrated in the drivers disc
for the B Series Line.
Hopefully, your campany will get a FORMAT C: by the end of this year.
arrivederci.

Hi, I am using an old PC P2 450Mhz, 256 MB Ram. Is ver 3.6.16 ok for my system or will it slow down the system? Thanks

Hi, I am using an old PC P2 450Mhz, 256 MB Ram. Is ver 3.6.16 ok for my system or will it slow down the system? NODD is the anti-virus. I am not happy with IE or goolge as these are taking too much space. Thanks

The system requirements for Firefox 3.6 are:
* Pentium 233 MHz (Recommended: Pentium 500 MHz or greater)
* 64 MB RAM (Recommended: 128 MB RAM or greater)
You exceed the minimum and are just short of the recommended processor. It should run OK but the only way to tell will be to try using it. Note that using add-ons can slow Firefox down, so if you start installing quite a few you may get performance issues.

Does adding 100Mbps Switch bring down the speed of a 1000Mbps network?

I have a wired Airport Extreme network where a 1000Mbps Ethernet switch in one room adds connections to other peripherals.
Now I want to add a switch in a different room for wired connections that are now operating wirelessly. And I have available a 10/100Mbps Ethernet switch. If I add that to the network do I bring down the speed of the entire thing? I realize that the connections directly from that 2nd switch can only be 100Mbps.
But will I affect the speed of the other connections?
Thanks in advance.

Correct

If my SSD on my Air is almost full, will it slow down the computer?

If my SSD on my Air is almost full, will it slow down the computer? As in, if I have about 20GB left on my SSD, will the computer run slower?

Rule of thumb tends to be that you should set aside 10% of disk space for SSDs for the best speed. This comes from SSDs in Windows PCs, where the SSDs do perform more slowly when full rather than having some free space. This is just how SSDs work, which I won't get into the technicalities of. The SSD controllers themselves allocate set a reserve space (this could not be true in Apple's case, depending on what chips they use), but generally the more free space the better. So 64GB should set aside 6GB, 128GB should set aside 12GB, and 256GB should set aside 25-26GB.
SSDs technically will never be as fast as when you first got it. They slow down as soon as you start to write data to them, but the slowdown will be negligible. It's still faster than a HDD at the end of the day.

HT3576 I have many apps where i must swipe down and it constantly brings down the notification screen. Is there anyway to disable this or activate it a different way because this really bugs me.

I don't have that problem. Perhaps I touch the screen lower when I wipe down? I don't know for sure but there's got to be some difference in the way that we wipe down. you might wish to do some experimenting.

Boot drive in Bay 3 or Bay 4 will it slow down the startup process?

If I have my boot drive in Bay 3 or Bay 4 will it slow down the startup process? I know in old PCs it would look for the boot drive by looking each time in a certain order. If the MP did that then it would probably look at Bay 3 and Bay 4 last on its ordered sequence.

But.... I think there is a but here... Mac OS does still look for other boot drives none the less.
On a PC, most have an option in the BIOS to set the device types (CDROM, hard drive, USB). and the order of hard drives to look. Meaning that I can have a system on a hard drive that is off line, pop it in, make it the primary boot device and boot from it, and boot quickly.
Sometimes people will disable a chipset or not enable hardware RAID on the motherboard.
Startup Disk control panel sets the boot path in nvram and even if you do have 4 boot drives in Mac Pro, it should still boot in 20-45 seconds.

Hi there Graham!
I have a couple of articles that can help you troubleshoot this issue. First, if you are downloading HD content, you will need to know the system requirements for HD playback, which can be found here:
iTunes: Purchasing and viewing HD videos
http://support.apple.com/kb/ht3209
Next, you will want to check your video playback settings on your Windows machine. The steps for that can be found right here:
Troubleshooting iTunes for Windows Vista or Windows 7 video playback performance issues

Hope that helps. Thanks for using the Apple Support Communities!

Will InDesign4 work with the newest MAC operating system -- OS10.9 I think.

Will InDesign4 work with the newest MAC operating system -- OS10.9 I think. My OS crashed and they have to wipe the computer to put on a new system. I don't want the latest system if it won't run CS4. I bought Creative Suite Cloud version and had nothing but problems with it and the system I was running. In fact all the problems with my computer started just after I put CS Cloud version on it.

Thanks for answering. I'll try to be more specific in my question.
