Guest wireless - too slow to get an IP

Hi All,
I am testing our new guest wireless using anchor controllers in the DMZ. The data path and the control path are both up and I can do eping and mping. The WLAN is configured to do a web passthrough. Whenever I try connecting to this new guest SSID, it always gets a 169.254.x.x address and it takes about 60 to 90 seconds before I get the right IP.
Currently, I am using the internal DHCP server on the anchor controllers since I only have a couple of users testing it but eventually I am planning to move the DHCP services to an external server.
Does anyone know why it is taking a long time to get an IP and start working? The client's MAC address shows up on the foreign controller and shows the status as associated and the policy manager status shows "RUN". I cannot seem to find any problems other than the slowness initially. Once I am connected, everything works as I expected.
Any ideas?

What code are you on ? There are known issues (bugs) with 6.x and 7.x code. In fact cisco has a special TAC release 7.0.98.4 that fixes the DHCP issue.
I would however, not use the DHCP on the controller. You have problems with leases after reboot etc ... Best to put it on a real DHCP server.

Guest wireless running slow 1 Mb for one of the foreign vWLC (AIR-CTVM-K9) , the Anchor controller is on DMZ (AIR-CT5508-K9)

Hi,
We have few vWLC (AIR-CTVM-K9) as the foreign controller for anchoring on difference site . The Anchor controller (AIR-CT5508-K9) is located at DMZ at the main site. The guess wireless are working fine for all the site except Site A . The download speed is <1mb and i do not see any restriction on the Foreign controller as well as the anchor controller . Upload speed could reach to 5Mb . I have check the configuration for other foreign controller and it is working fine and have the similar setting . Could you please shed some light on where should i start to troubleshooting this . User are able to get the correct ip address, gateway , dns server ip address without any issue.

Issue resolved . End out it is the Qos apply on the vWLC switch port that slow down the speed. Remove the Qos do the trick.

Forall bulk delete is too slow to work,seek advice.

I used PL/SQL stored procedure to do some ETL work. It is pick up refeshed records from staging table, then check to see whether the same record exists in target table, then do a Forall bulk deletion first, then do a Forall insert all refreshed records into target atble. the insert part is working fine. Only is the deleteion part, it is too slow to get job done. My code list below. Please advise where is the problem? Thansk.
Declare
TYPE t_distid IS TABLE OF VARCHAR2(15) INDEX BY BINARY_INTEGER;
v_distid t_distid;
CURSOR dist_delete IS
select distinct distid FROM DIST_STG where data_type = 'H';
OPEN dist_delete;
LOOP
FETCH dist_delete BULK COLLECT INTO v_distid;
FORALL i IN v_distid.FIRST..v_distid.LAST
DELETE DIST_TARGET WHERE distid = v_distid(i);
END LOOP;
COMMIT;
end;

Justin:
The answers to your questions are:
1. why would I not use a single DELETE statement? Because this PL/SQL procedure is part of ETL process. The procedure is scheduled by Oracle scheduler. It will automatically run to refresh data. Putting DELETE in stored procedure is better to executed by scheduler.You can compile SQL inside a PL/SQL procedure / function just as easily as coding it the way you have so that's really not an excuse. As Justin pointed out, the straight SQL approach will be what you want to use.
>
2. The records in dist_stg with data_type = 'H' vary by each month. It range from 120 to 5,000 records. These records are inserted into target table before. But they are updated in transactional database. We need to delete old records in target and insert updated ones in to replace old ones. But the distID is the same and unique. I use distID to delete old one and insert updated records with the same distID into target again. When user run report, the updated records will show up on the report. In plain SQL statement, delete 5,000 records takes about seconds. In my code above, it take forever. The database is going without any error message. There is no trigger and FK associated
3. Merge. I haven't try that yet. I may give a try.Quite likely a good idea based on what you've outlined above, but at the very least, remove the procedural code with the delete as suggested by Justin.

I have an ipad3(wifi +cellular). Now i want to upgrade my iOS5.1 to ios 7. But download speed in our country is too slow(100kbps). It can be disconnected anytime. Is there any problem if net connection get disconnected while upgrading ios? Please ans me.

There is something Definitely wrong with iOS 7 regarding DATA USAGE being logged to wireless carrier in for WIFI instead.
I read all the previous replies and same issue.
I rarely use my mac to sync....its all wifi sync for the last 2 years....never had this issue before... and i know it began with iOS7.... here is why....
My iPhone was at home when I updated to iOS7 connected to wifi...but it logged Data Usage to Rogers Wireless (700MB approx)...data will never do an update over 50mb in app store (it gives the warning to use wifi) I play a lot of games and pay for them so I always update through App Store. 2 weeks later, simposons halloween update (650mb)...at home, using wifi.
Rogers told me there was 700+mb data usage on the day of update and 650+mb data on oct 1.st (tapped out).
Went over my 6GB plan and paid the fees.
This has never happened before...It must come to apples attention by now...

Why am I getting this error message, "Disk is too slow. (Prepare) (-10001)"

Hello all! I've been using GarageBand for a while now and I've accumulated quite a few files. Along with all of my movies and iTunes library, my internal hard drive filled up rapidly and I didn't catch it. I received a warning message on my screen one day saying that my hard drive was nearly full and I only had a few MB available. I'm using a 150 GB Solid State Hard Disk on my 2009 MacBook Pro (2.6 GHz Intel Cre 2 Duo, 4 GB of RAM). I remembered reading a while back that it's better to use an external hard drive for pretty much everything when using Garageband, so I bought one. I now have a seagate 500 GB, 5400 rpm external (USB 2.0) and I moved ALL of my movies and music over to it. I freed up around 60 GB of space on my internal hard drive in doing so.
So now that I've given you a little background, let me explain the issue I'm having. Before I noticed that my hard drive was full, I started receiving this error message:
Disk is too slow. (Prepare)
(-10001)
Upon receiving this message, I was unable to do pretty much anything in GarageBand. I couldn't listen to tracks, export to iTunes, or do anything! All I'm using GarageBand for is editing. My band and I do all our recording (and mixing) offsite at a separate studio and i just deliver a 2 track stereo signal (L/R) to my MacBook. From there, I just cut the individual tracks from a block of 30-45 minutes of recording because we just record our entire studio session and mix everything there. I pretty much never have more than two tracks and a few effects going at the same time.
After I realized that my disk was nearly full, I consulted my brother-in-law. He's head of the IT Deartpment at a major hospital here in West L.A. and he told me that I may have created a problem with the cache by filling up my internal hard drive and that I may still have issues with performance even after I free up space. He then told me that I may need to reboot my MacBook a few time to "free up the cache" (or something close to that, sorry guys I'm not that tech-savvy). It seems he may have been right, as I'm still experiencing the same issue. I rebooted around 10 times overall to no avail. I'm still using my internal hard drive to store the files that I'm working on (temporarily) because USB 2.0 is way too slow for my liking, when using GarageBand.
I've read quite a few articles on this offering solutions such as:
1. Do a complete Uninstall and Reinstall of GarageBand
2. Clone my hard drive to my external, format it, and reinstall everything back on it
3. Get a hard drive that supports Firewire 800 (The HDD I bought is USB 2.0, but it has two USB cables to increase speed, but I only have 1 port and I tried a powered USB Hub, but this HDD won't work with it for some reason).
4. Use different editing software.
5. Take it to Apple!
Will any of these things fix my problem? Are some better than others? Before I do anything, I wanted to ask this question on the furum to see if anybody had an easier (or cheaper!) solution. Any suggestions, tips, or advice would be much appreciated, as my band is starting to get on my case about finishing our CD! Thanks...

Have a look into the Preferences folder (YourUserFolder/Libraries/Preferences/) and trash all Logic preferences.
You'll have to setup the program again.

Golive CS2 too slow on my Mac g5 to get any work done?

For the past 2 years I have been slowly building a rather large web site (about 2000 hours invested). We will be selling items we import from india (my girlfriend and I spend 3 moths a year in India) and then there is an entire section on India travel tips, photos and travel logs.
I am pleased with Golive 6.01 and recently converted my site to CS2, just to find it is very slow on my macintosh G5 and many weird bugs And site looks the same as in 6.01 when previewed in various browsers. Also in CS2 when I click on preview button, the page I want to work on closes and the page that brought me to that page pops up.
I bought a G5 macintosh which should run CS2 more quickly but:
I have yet to see my site in Explorer 7 for Windows because Microsoft did not make Explorer for Mac after version 5.0.
My question is:
Why not complete site in 6.01 and then before it is published convert to CS2. I can't get anything done with CS2 it is just way too slow.
Thanks Stuart
(Could installing 2 versions of Golive on one drive be generating the bugs?)

Hi all:
Been cleaning up Site (weird files not in my site but on desktop keep showing up as errors) got ride of them. Turned of my internet connection). Things seem to be getting better.......for now. Working on G4....will move to my G5 and see.
Might pull this one out.
Why several target files with only one source show as an error is an irratation because help says it's not really an error and can be ignored.
OH...one quick question do SOURCE files get uploaded to host when one publishes? Or perhaps a better question! Do SOURCE files need to be uploaded to host. I suspect not...but I also suspect It's OK..might just slow things down a bit?
Thanks to all of you.....this miserable world needs more like you all!

Read and follow the Bootcamp Installation instructions that you were offered to view when you ran Bootcamp Assistant.
Run Bootcamp Assistant again and select the option to download the Bootcamp Support software. Follow the instructions. Then boot into Windows and install the Windows Support software you downloaded and saved.

What cable do I need for a full migration from a 2011 MacBook Pro to a new current one-wireless migration way too slow.?

What cable do I need for a full migration from a 2011 MacBook Pro to a new current one-wireless migration way too slow.?

All you need is an Ethernet cable.
Just plug it into both machines. Don't bother with a crossover cable, just a plain old Ethernet cable will do. The Ethernet ports on the Macs are smart and will adjust appropriately.

I'm getting "the disk is too slow (prepare)" message

I'm getting "the disk is too slow (prepare)" message when trying to do literally anything in garageband right now, even with all other programs shut down, correct energy saver settings, and only one audio track in garageband.
Everything else on my macbook pro is running fine, iMovie, Safari, etc... so it seems like a garageband problem to me. I updated garageband, have reset computer multiple times, I don't know what else to do... it feels like garageband is keeping all of my recent projects open in the background at once, but when I check my windows, that is apparently not the case. Any help?

Anyone have any ideas to help?

Hi i use a macpro i7 wt 7200rpm internal drive i get this message Disk is too slow-(prepare) (-10001) when i am using logic 9

Hi i use a macbook pro 17" 2.66ghz intel core i7 with 8gb ram & a 500gb@7200rpm internal drive i get this message "Disk is too slow. (Prepare) (-10001) when i am using logic 9 wiyh just a 5 vsts loaded 2 of them being esx24's . i used to not get this warning earlier in the same or even heavily loaded projects.
When i press play the beachball appears for a minute or so then the message.
Even when i open up a new project a beachball appears for about 30-40 secs and then the project opens up
i have even tried opening up the projects w/o any vst's loaded (i have disabled them from audio units manager)
Initially i thought it was a hard drive problem so apple had it replaced for me but i am still encountering the same problem.
have even tried disabling the sudden motion sensor from terminal no luck there too
tried reloading osx 10.6.7 no luck there too
what do i do

How full is your 500 GB hard disk?
Do you have 10% to 15% free space available?

I just installed Lion and the newest version of Logic express 9 (9.1.5) and every time i playback audio I get this error message: [Disk is too slow or System Overload. (-10010) . Never had any issues before now...

I just installed OSX Lion (10.7.2) and updated to the newest version of Logic express (9.1.5) on a macbook and every time I playback audio I get this error message: [Disk is too slow or System Overload. (-10010) The Sudden Motion Sensor may have parked the hard drive head, or the disk performance is not sufficient to read or write all audio tracks, or the system was not able to process all data in time]
Never had any issues before now... any ideas?

haha, so now i'm thinking. I'm learning the terminal as fast as i can but there are several lines of codes and commands in there that throws up red flags to me that i don't fully understand. It just looks fishy too me. It would be highly appreciated if someone could just check this out just to tell me that i don't need to worry about it. Or point me in the right direction. I just feel un easy about this. ha.

You may not be able to get a refund, since the terms of sale for the iTunes Store state that all sales are final. You can contact the iTunes Store, explain the reason for your request, and ask, though:
http://www.apple.com/support/itunes/contact.html
It's possible they'll make an exception for you, particularly if the problem was on their end preventing the movie from downloading in a reasonable time.
Good luck.

Getting attribute properties from client tier is too slow

Getting properties for view object attributes is too slow, because a called to the server is made for every attribute.
I noticed that when a property is gotten for an attribute all properties are retrieved for it, but I couldn't found a way to get all properties for all attributes in the ViewObject.

See ApplicationModule.fetchAttributeProperties and it's usage in JClient in JDeveloper 9.0.3

The servers gets too slow with JMS Messages

Hi all,
      Look, Im usin JMS services, with MDB, and work good. Also i kepp a Queue to wronly messages (basiclly for comunications between R3 and Portal). Thats messages have seted a "Time to Live" equals to one day, so, they dissapair when this time are completed. But for some reasson, my server gets too slow and show exeptions of Time Out. Maybe the messages are not "killed" really, and consume memory from the server or some like that.
      The think are, that im deleting manually the Queue from the Visual Administration, later than this, the process back to keep the execution time and gets faster.
      If some know some or had this same trouble, please help me...
Thanks in advance,
Jorge.

I see. Thanks for your advice
I always had this setting on my previous devices (Sony Xperia X10 pro, Samsung Galaxy Slll) and thought it wouldn't do anything. It just got slow when it actually was updating.
Now I turned that setting off, the wifi worked quite long again (10min) but then it was gone. Unfortunately.
