Redirect WCCP and Performance hit on 3750
Maybe it's more of a "resizing" qtn more than anything else.
Yesterday, I activated wccp redirect on a stack of distribution has collapsed/3750 of base, in an office with 150users. WAI is model 612.
As soon as the configuration of the redirect has been applied, I found the network slowing significantly and received an event alert CPU of NEM, reports that CPU on 3750 stack exceeds the set threshold (65%). Put the threshold on the one hand, the cli is terribly slow and so I removed immediately redirect to the relevant interfaces. He bought the network back to normal in terms of performance.
Is this a calibration problem or maybe a bad configuration or something else...?

Here is a list of best practices to follow to do forwarding of wccp on hardware platforms such as the 3750. I found it in the link below.
http://www.Cisco.com/Web/services/news/ts_newsletter/tech/ChalkTalk/archives/200806.html
The following best practices should be applied to the implementation of WCCP on a hardware platform:
- L2 transfer
- Assignment of mask
- Interception of incoming traffic
- No ' exclude ip wccp redirect in.
Your configuration "output method negotiated return of interception-method wccp" will appeal to a WCCP GRE tunnel to create of the 3750 to CAI. All traffic will be then be redirected a software based on this configuration line.
"Game of negotiated return as the method of evacuation. With this specification, the Cisco WAE uses GRE to return traffic redirected to the router intercepting. Note: in this case, WCCP negotiated WCCP GRE return method. »
I'd stick to best practices that Zach has described in the link at the beginning of this post. It's a very well written on the WCCP redirect article.

Redirect button AND perform the dynamic action
Hello
I use Oracle 11 g and Apex 4.2.2
It could be a matter of beginners (but that's what I'm ;-)) but I'll ask anyway.
I created a button and can "redirect to the Page in this application" in the section "Action when the button clicked" or select "defined by the dynamic Action."
Is there a way to select "Redirect."... "AND run the SQL Code?
This is exactly the situation that I was considering. You start at the apex (which means don't not offensively or anything like that) and so the concept of session state can still be fresh for you. Telling me where you're just complicates things for yourself.
Why do you, or makes you think, that you need to run plsql in dynamic action first and then redirect the page?
Running code plsql already involves tracking session state and would require the value of the required items on the server. Running WHAT PLSQL is on the side server, if a call should be made. Given that you want to redirect afterwards, the call should happen synchronously, IE make the browser wait the result in order to continue to the next step. A redirect will just tell the server to send the new page to you.
So why would not just use a send page? A page sent will submit all values of item on the server and thus session state. You can use the values of calculation and validation processes and never worry about having properly put it. You can filter out inappropriate process etc. According to the values of query (for example submit) so no problem there. Finally, a branch should redirect you to the target page. Remember, a branch is a part too and is essentially a redirect server-side. Find yourself on your new page without problem really and just send 1 page (send page, get another back essentially).
That said, I simply don't consider a dynamic action. It is useless to laregely here and creates more problems than is useful to review more.
What you have now is to redirect the client to another page, but in the process, you have lost everything from the original page. No values are stored in the session to all State: no save manual to submit State or session page. Add the element to the redirect link doesn't work either, as the link is built during rendering and is not dynamic (so no ' regenerated' link when you click it).
Again, I advise you to:
-put the button to send the page
-create a process after you submit and run your plsql code
-create a branch to a point after the process and set it to redirect to the target page
or
-put the button to send the page
-create a branch set up to redirect to the target page
-create a process on the target page and run your plsql code (but be aware that it may have to be executed conditionally)
There are several traps on session state, so when you feel better grasp it. Page submits are not all that bad.

Tecra W50 - Has R/W - speed and performance
Hi, received the new Tecra W50 - a and have to say I'm gutted with the speed and performance.
8.1 we partitioned the drive 50-50 and the reading/writing is terrible. If I copy from C: to D: I lucky to get 10 Mbps
Copy from or to external Sata I get more of 50mbps and around the same by ethernet.
I got rid of the partition and tried to copy locally and get the same result.
The Task Manager displays disk to 100% performance all the time and I can't do with my machine while copying going on.
Copied 2gig file 1 and it happens in seconds. Try a folder with a few thousand of files and everything grinds to stop.
Any ideas greatly appreciated

Type of drive is MQ01ABD100H 1 TB and I have 3 machines to do the same thing
There is an SSHD (SSD hybrid drive) a combination of SSD and HDD.
SSHD performance depends on the cache controller (SSD).
Why?
The flash cache is used for the most used data... the special controller must decide what data will be loaded into the cache.
But the SSHD needs some time to 'learn' data that uses the cache and the write speed at the beginning would be similar to the common HARD disk.
After some time this performance will increase and the SSHD should reach the higher writing speed. -
My mac mini (mid-2010) speed/performance is very slow - think of it as a result of letting my kids do "whatever" about it in recent years. Need help, consolidate the files, software updates, etc. in order to improve the speed and performance. You will also need to get data out of old PowerBook G4.

Satellite P200 - 1 K 9 and performance issue
I hope IM this ad in the right area...
Hello
I have a Satellite P200 - 1 K 9 with the following specifications:
Intel Core 2 Duo T7700 @ 2.40 GHz CPU
3 GB RAM
32 bit
Note Windows experience 4.8ATI Mobility Radeon HD 2600 map graphic and one
HD sound card...My problem is that since I bought my laptop about 7-8 months ago slowed down the performance. Of course, since then I had filled my hard drive (partition) with the media and understand that this is at the expense of the performance of the system. However, since this grateful I released a lot of disk space. I have 40 GB free on my C: and 90 GB free on my D:. Total, shared capacity is 250 GB (125/125).
Basically, while being largely ignorant of the technical questions, laptops and technology altogether, the way I noticed the inability of systems to "return" to its original factory running (which, I might add, I was very impressed by) is when it comes to games. Football Manager 2009, for example running very slowly. I had a peek in the Task Manager, because I play the game in a window, and the CPU usage works 100%, although I'm sure the culmination of the individual tasks and Applications is not equivalent to that (maybe there is a program hidden Hogging my CPU speed?). Call of Duty 4, which took place on medium-high graphics settings when the laptop was new, now struggles on the lower graph and the sound settings, without that there is a problem with internet connectivity. In addition, (for reference, I m not not the game breath) Battlefield 2, which is about 3-4 years of age very slowly also works. He ran too extremely fast, on the highest graphics settings when the laptop was brand new.
Basically, what I want to do, is to return the system to its original performance. It is always too slow when two hard drives were full of games and media. Now, despite the withdrawal of many of them, the system works like a sloth.
Means I ve done to solve performance problems are: disk defrag, disk clean up, error checking, virus scan (with Kaspersky), scanning of spyware (with PC tools Spyware Doctor), deleted the old files with CCleaner and erased files not deleted with a program called eraser... As well as the release of about 50% of the disk space.
Add to that, I ve noticed performance was much more when I first turn on the laptop and the sides of it n t had the chance to become hot. I understand what is normal, and he did before when the laptop was new and was operating at optimum performance, but perhaps I have an overheating problem? I'll let you know what is the temperature, but I put just t know.
I hesitate to return the system to its factory settings and if necessary I'll take to a computer store, if there is something they can do. But in the meantime I d like to listen to any advice on general issues that I face, and possible solutions to my problem.
Thank you very much.
The problem with Windows is that it becomes slower and slower that you operate.
When the devices and programs are installed, they increase the size of the registry, activate the Services, add resident DLLS and drivers, slow down the file system by adding thousands of files. As well, the operating system can get damaged after some time due to the loss of power and software poorly written.
Even if you use CCleaner and other utilities and uninstall several programs, it is never as fast as a fresh installation of windows. Uninstalling programs rarely remove the program completely 100%.The antivirus can have a huge effect on performance, that's why the system runs great when the image of the plant is installed (which has usually no anti-virus).
So basically if you want the system making a lot once again, you must back up your data and perform the recovery. I myself do it once a year to restore performance.

Reliablity and performance monitor is empty
I was just playing on Vista, now that I finally got and decided to launch the performance and reliability monitor to see why my computer was using up to 1.6 GB of RAM at idle. Not that she really bothers me or hurts my performance of the computer (after x 64 windows and 6 GB of RAM), but after opening it, I was a little confused because nothing was actually happening. I went to the monitor tab, you press start, but who have done nothing. I also tried to pass through the computer management program, but the same exact results. The work of monitors of reliability and performance, but the main screen, which shows the performance used by individual programs won't give me empty graphs, of the options and outcomes - although lack of. Any help would be great.
This is just a screenshot of what happens:
http://i562.Photobucket.com/albums/SS68/ThuggyWuggy/NewBitmapImage.jpgWell, I did everything what should have made the monitor, at least, I don't think that I did... the only thing that I changed the activation cool no silent mode for my CPU on my motherboard options, so I would not use too be able to leave my computer on all night. The monitor now works... If it stops working again, I'll post, but that seems to have been the cause. (?) It seems weird to have solved anything, but w/e... I do not know... I don't understand. I'll leave it is open for a day to make sure that it is the question. If this is the problem my motherboard is a version of Platinum bios msi k9a2 1.4, so others know how to solve this problem.

I have Vista Home Basic. I have a HP printer that whenever I logged in re-installed drivers. So I decided to uninstall all printer and software and re-install fresh. All seemed well and good work but if I restart or stop and come back on the laptop tells me a driver went on a buffer and performs a restore of the system. The system restore seems to work and restores me awhile before I re-installed the printer. But again if I restart or stop it has the same problem. the pilot and buffer. I have not yet installed or reconnect the printer because it restored. I don't know much about computers and I don't know what to do. I wanted to kind of do a clean install of Vista but it comes preinstalled on my laptop so I don't have a disk and that I read removing the drivers does not seem an option.
Hi ChristopherParvin,
You did it happen any changes made to the computer before the show?
Method 1: Try the following steps.
a. log in your computer using an administrator account.
b. Click Start and then click Run.
(c) in the Open box, type regedit and then click OK.
d. Locate and click the following registry key:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\LPTENUM5. Right click on the registry key and then click on remove.
e. under confirm delete key, click Yes.
f. close the registry editor and restart your computer.
Important: this section, method, or task contains steps that tell you how to modify the registry. However, serious problems can occur if you modify the registry incorrectly. Therefore, make sure that you proceed with caution. For added protection, back up the registry before you edit it. Then you can restore the registry if a problem occurs. For more information about how to back up and restore the registry, click the following article: back up the registry in Windows 7Method 2: I suggest to install the drivers of clean boot and then restart the computer and check if the problem persists.
