VoWLAN Problem over WLC5508 / AP1242

Hello,
Our customer has moved his access points from the WSIM in 6509E (Version 7.0.230.0) to the Controller WLC5508 (version 7.4.100.0). Since then he has in the area of "Access Points 1242" massive problems with VoWLAN. In the vicinity of 3602 AP, there is no Problem?
They use the following VoIP Environment: Cisco 7921G and 7925G phones, Call-Manager version 8.6.2.22900-9, Phone Load CP7921G-1.4.2-1.4.2 / CP7925G.
In SYSLOG we found the following entries:
# MM-4 PMKCACHE_ADD_FAILED: mm_listen.c: 8216 Failed to create PMK / CCKM cache entry for station 00: c0: af: *********
We found nothing that helped us of the bug notification at:
https://tools.cisco.com/bugsearch/bug/CSCui50431
I need urgent help. Our client have massive problems in the enviroment of the 1242 Aps. This is a business critical for the customer!
Thanks for quick support

Interactive report performance problem over database link - Oracle Gateway

Hello all;
This is regarding a thread Interactive report performance problem over database link that was posted by Samo.
The issue that I am facing is when I use Oracle function like (apex_item.check_box) the query slow down by 45 seconds.
query like this: (due to sensitivity issue, I can not disclose real table name)
SELECT apex_item.checkbox(1,b.col3)
, a.col1
, a.col2
FROM table_one a
, table_two b
WHERE a.col3 = 12345
AND a.col4 = 100
AND b.col5 = a.col5
table_one and table_two are remote tables (non-oracle) which are connected using Oracle Gateway.
Now if I run above queries without apex_item.checkbox function the query return or response is less than a second but if I have apex_item.checkbox then the query run more than 30 seconds. I have resolved the issues by creating a collection but it’s not a good practice.
I would like to get ideas from people how to resolve or speed-up the query?
Any idea how to use sub-factoring for the above scenario? Or others method (creating view or materialized view are not an option).
Thank you.
Shaun S.

Hi Shaun
Okay, I have a million questions (could you tell me if both tables are from the same remote source, it looks like they're possibly not?), but let's just try some things first.
By now you should understand the idea of what I termed 'sub-factoring' in a previous post. This is to do with using the WITH blah AS (SELECT... syntax. Now in most circumstances this 'materialises' the results of the inner select statement. This means that we 'get' the results then do something with them afterwards. It's a handy trick when dealing with remote sites as sometimes you want the remote database to do the work. The reason that I ask you to use the MATERIALIZE hint for testing is just to force this, in 99.99% of cases this can be removed later. Using the WITH statement is also handled differently to inline view like SELECT * FROM (SELECT... but the same result can be mimicked with a NO_MERGE hint.
Looking at your case I would be interested to see what the explain plan and results would be for something like the following two statements (sorry - you're going have to check them, it's late!)
WITH a AS
(SELECT /*+ MATERIALIZE */ *
FROM table_one),
b AS
(SELECT /*+ MATERIALIZE */ *
FROM table_two),
sourceqry AS
(SELECT b.col3 x
       , a.col1 y
       , a.col2 z
FROM table_one a
    , table_two b
WHERE a.col3 = 12345
AND   a.col4 = 100
AND   b.col5 = a.col5)
SELECT apex_item.checkbox(1,x), y , z
FROM sourceqry
WITH a AS
(SELECT /*+ MATERIALIZE */ *
FROM table_one),
b AS
(SELECT /*+ MATERIALIZE */ *
FROM table_two)
SELECT apex_item.checkbox(1,x), y , z
FROM table_one a
    , table_two b
WHERE a.col3 = 12345
AND   a.col4 = 100
AND   b.col5 = a.col5If the remote tables are at the same site, then you should have the same results. If they aren't you should get the same results but different to the original query.
We aren't being told the real cardinality of the inners select here so the explain plan is distorted (this is normal for queries on remote and especially non-oracle sites). This hinders tuning normally but I don't think this is your problem at all. How many distinct values do you normally get of the column aliased 'x' and how many rows are normally returned in total? Also how are you testing response times, in APEX, SQL Developer, Toad SQLplus etc?
Sorry for all the questions but it helps to answer the question, if I can.
Cheers
Ben

Syncing problem over cloud for all my devices

I have severe syncing problems over the cloud with all iWorks apps (Pages, Numbers, Keynote) across ALL my devices (iMac, MacBook, iPad2, IPhone4) and even on web: It JUST DOESN'T WORK!!!
Internet works perfectly, Docs sync is set to ON in every device, but since 6 October 2012, syncing was stoped for unknonw reasons.
I tried to find someone to contact for by email, but it was impossible. So I ended up here ...
Can help someone?

For each device, backup first, then on the device use Settings > General > Software Update. Each one still has to download the update individually, but they are smaller files so should download more reliably.

Have this problem over a month now

Afternoon everyone,
Where should I start..
About a month ago my hub started resetting itself whenever I used internet, i spoke to numerous amount of people over at the call centre and about 2 weeks after calling them nearly every day they sent openreach engineer over to my house to check whats going on. He did what he had to do inside my house and outside my house, then he did some tests which all said "passed", but hey after the visit i went straight on my computer and checked the speeds which were at about 1mb at the time which still are not good enough considering i had 6-8mb about 3 months ago, anyway back on the subject i contacted bt yet again and they said the line needs to be running few days for the connection to stabilise. A week of waiting and still nonthing speeds the same and my hub was still resetting itself but not as often as it used to. After a week I decided im not going to bother with those useless people in the call centre so I emailed bt and started to explain my problem all over again, first they sent an engineer to my exchange to see whats going on there, still nothing improved after that. They then decided that they should send an engineer again which came to my house yesterday and replaced the master socket and also did other things which i didnt see. He then like the first engineer did some tests and he said that the speed hes getting from the master socket is 9.7mb i was all excited that i finally got back speeds i used to have about 3months ago but hey, went on the computer straight away after the visit and the speeds were at 500kb/s. I had an idea today that maybe i should bring my computer downstairs with the hub and connect it to the master socket but still nothing.. same speeds and the hub is still resetting from time to time, if i counted correctly the hub resetted 7 times today and 4/7 of them resets the hub didnt connect to the broadband for about an hour and on one reset it didnt connect for 4 hours the rest connected in about a minute. This is really going beyond a joke now, really unuhappy with the whole situation which i repeat had for over a MONTH now. Im thinking of changing to another ISP and as bt said if i change from bt to any isp the problem will still remain id prefer to talk to normal people and not the callcentre which as a matter of fact everybody knows is useless and you can barely understand what they are trying to say due to obvious reasons.

My MacBook Air keyboard isn't working, except the power button. I had the same problem over the summer and had it repaired ~4 months ago. What should I do?

The keyboard of my 11-inch MacBook Air, purchased in November 2011, isn't working at all. None of the keys respond except the power button. I'm able to restart the computer, and have done so multiple times. I've attempted SMC and PRAM resets, but they haven't worked.
I've never spilled anything on the laptop, haven't stepped on it, and haven't otherwise damaged it ever. I use the laptop very lightly. I only use it to take notes for class, browse the Internet, and watch movies. I don't download anything but PDFs, PowerPoints, images, and Word documents. I don't even have music on it. So I don't think I had any part in creating the problem.
I had this same problem with my laptop over the summer, and I took it into the Apple Store to get it repaired for $200. They told me that they didn't know the cause of the problem. I think they replaced the bottom half of my laptop entirely (receipt says there's a new "Housing, Top Case with Keyboard, US") and told me the problem was fixed. This was on June 30. The laptop keyboard stopped working again today, October 19. I called Apple Support and they told me that I would have to pay for the repair again because it's been 90 days since the last repair. I'm annoyed and upset that I have to pay $200 again to re-repair a problem that should've been properly fixed the first time. Plus, if the problem keeps happening despite multiple repairs, I can't afford to keep getting the laptop repaired over and over again due to the Apple employees' incompetence.
Does anyone have any advice on how to fix the laptop? I'm a grad student and don't have the funds to pay for another repair, and there's no way for me to get to an Apple Store without hiring a car service, so I'm trying to avoid going to the store if possible. Thank you.

Get the new keyboard at eBay and replace by yourself may be cheaper way, though you're required higher skill and well know about MacBook Air.

Problem - over lie of data series in Line chart (Web Application Designer)

Dear Experts,
I have created a chart with below requiments from my user by using web application designer.
1) Key Figure 1 (Chart type -> column )
2) Key Figure 2 (Chart type -> column )
3) Key Figure 3 (Chart type -> Line; color assigned -> BLACK;    Visibility: Visible)
4) Key Figure 4 (Chart type -> Line; color assigned -> YELLOW; Visibility: Visible/Hidden)
5) Key Figure 5 (Chart type -> Line; color assigned -> RED;         Visibility: Visible/Hidden)
The line chart of Key Figure 3 must always appear in Front then others Key Figures.
Then following by, Key Figure 4. Last is Key Figure 5.
As I know the order of display line chart is infflucing by the order of Key Figure in structure by descending, likes below
1) Key Figure 3 (Rank of front -> 3rd; Chart type -> Line; color assigned -> BLACK;    Visibility: Visible)
2) Key Figure 4 (Rank of front -> 2nd; Chart type -> Line; color assigned -> YELLOW; Visibility: Visible/Hidden)
3) Key Figure 5 (Rank of front -> 1st; Chart type -> Line; color assigned -> RED;         Visibility: Visible/Hidden)
So, I have conflict on fulfilling these 2 request on assigning the color and control their visibility and lines over lie.
Please advice me if you have any suggestion on controlling the lines order.
Thanks!
~ GP

Hi Priya, thanks for input.
I think I should further elaborate the problems. Thanks for your highlight.
I have a lines chart with five key figures. So my chart will have five lines.
Some lines from chart will overlap if the data are same.
When overlapping of lines happens, I want to control the order of which series should be appear first.
Likes below example,
1) Key Figure 1 (Chart type -> column )
2) Key Figure 2 (Chart type -> column )
3) Key Figure 3 (Chart type -> Line; color assigned -> BLACK; Visibility: Visible)
4) Key Figure 4 (Chart type -> Line; color assigned -> YELLOW; Visibility: Visible/Hidden)
5) Key Figure 5 (Chart type -> Line; color assigned -> RED; Visibility: Visible/Hidden)
           KF1 KF2 KF3 KF4 KF5
CW 1    30     30    80    80    50
CW 2    40     50    90    60    90
CW 3    70     50    90    90    90
CW 4    80     70    70    90    70
As you can see, there is overlap in these value.
CW 1 KF3, KF4 -->80
CW 2 KF3, KF5 --> 90
CW 3 KF3, KF4, KF5 --> 90
The order which i want the series should appear first when overlapping.
- KF3 must appear on top.
- Then, follow by KF5
- Last is KF4.
So now, i have no idea to control the overlap orders except adjusting the sequence of keyfigure from query.
Feel free to give me any input!

Ichat problems over apple network

We have 2 WDS network participating airport express base stations connected to the internet via Comcast cable. The network is really fast and we never had a problem with multi-way video chatting inside or outside the house.
Now that the family upgraded to leopard, we can't screen share via AIM or bonjour (connection doctor says we don't have capabilities because the network is too slow. We can video chat and it's extremely fast, but when I enabled the effects, we were disconnected.
It seams that 2 mac laptops connected with the latest software over a relatively standard apple network should work...

Hi
Set the Quicktime streaming setting, goto sys prefs/quicktime/streaming/streaming speed, set to 1.5mbps(dont use automatic)
In ichats prefs click on video and change bandwidth limit to 500.
Restart iChat.

Macmini 2010 sound problem over hdmi

Hi, my name is Diego im from Argentina, well i have a problem with my macmini 2010 unibody, i have set up the mini over hdmi in to my receiver ( yamaha 663 ) and hdmi out to my LCDTV, i set up in sound properties HDMI output ok all is fine but if i am listening music in itunes and turn off the tv the signal is off to receiver and the music sounds in the built in speaker of the mac mini, any idea to disable this speakers o built sound card ? i want to passtrough over hdmi with the TV off, thanks to all best regards, Diego.-

I still get daleks too from time to time if I try to use 1080i with Dolby Digital into a Sony Bravia.
The BT Vision box HDMI is known to be flaky, though it sounds like you've got an extreme example of the problem with the Tosh.
It's possible to improve things a bit by using an HDMI extender to recondition the signal before it enters the TV. It might be worth a try. Try http://www.hdcable.co.uk/

Problem over VAN starting IR and ID

hello experts
I am facing a problem starting XI server over VAN. Everytime i have to manually add the domain name in the URL to start IR and ID.
Moreover i am not able to get JAR file through java web start.
Can anybody please solve this problem.

Hello Deepanjali
We also faced the same problem. All we did was very simple.
just maintain an entry in the ETC\HOST file (system32\drivers\etc\hosts) as your server name = complete path.
also check your java version, try downloading JRE 1.4
I hope it would solve your problem.

Large file transfer problems over client/server socket

Hi,
I wrote a simple chat problem in which I can send files from client to client. The problem is when I send large files over 101 MB the transfer freezes. I do not even get any error mesages in the console. The files I am sending are of any type (Ex mp3, movies, etc...). I am serializing the data into a "byteArray[packetSize]" and sending the file packet by packet until the whole file has been sent, and reconstructed on the other side. The process works perfectly for files smaller than 101MB, but for some reason freezes after that if the file is larger. I have read many forums and there aren't too many solutions out there. I made sure to use the .reset() method to reset my ObjectOutputStream each time I write to it.
Here's my file sending code:
byte[] byteArray = new byte[defaultPacketSize];
numPacketsRequired = Math.ceil(fileSize / defaultPacketSize);
try {
int i = 0;
reader = new FileInputStream(filePath);
while (reader.available() > 0) {
if (reader.available() < defaultPacketSize) {
byte[] lastPacket = new byte[reader.available()];
reader.read(lastPacket);
try {
if (socket == null || output == null) {
throw new SocketException("socket does not exist");
output.writeObject(lastPacket);
output.reset();
output.writeObject("DONE");
output.reset();
output.close();
socket.close();
catch (Exception e) {
System.out.println("Exception ***: " + e);
output.close();
socket.close();
else {
reader.read(byteArray);
try {
if (socket == null || output == null) {
throw new SocketException("socket does not exist");
output.writeObject(byteArray);
output.reset();
catch (Exception e) {
System.out.println("Exception ***: " + e);
output.close();
socket.close();
reader.close();
catch (Exception e) {
System.out.println("COULD NOT READ PACKET");
Here's my file receiving code:
try {
// The message from the client
Object streamInput;
FileOutputStream writer;
byte[] packet;
while (true) {
streamInput = input.readObject();
if (streamInput instanceof byte[]) {
packet = (byte[]) streamInput;
try {
writer = new FileOutputStream(outputPath, true);
writer.write(packet); //Storing the bytes on file
writer.close();
catch (Exception e) {
System.out.println("Exception: " + e);
else if (streamInput.equals("DONE")) {
socket.close();
input.close();
break;
catch (Exception e) {
I'm looking for any way I can possibly send large files from client to client without having it freeze. Are there any better file transfer ways other than socket? I don't really want FTP. I think I want to keep it HTTP.
Any suggestions would be helpful.Thanks!
Evan

I've taken a better look a the code you posted, and
there is one problem with the receiving code. You
keep repeatedly opening and closing the
FileOutputStream. This is not going to be efficient
as the file will keep needing to be positioned to its
end.Yes sorry I did change that code so that it leaves the file open until completely done writing. Basically I have a progress bar that records how far along in the writing process the client is, and when the progress bar reaches 100%, meaning the file is complete, the file.close() method is invoked. Sorry about that.
I also ran some memory tests using the "Runtime.getRuntime().totalMemory()", and "Runtime.getRuntime().freeMemory()" methods. I put these methods inside the loop where I read in the file and send it to the client. here's the output:

ClassLoader problems over IIOP

I'm currently porting our application from WebSphere to WebLogic and I have got the following issue concerning class loading on the client side:

Is it a problem for WebLogic to transfere Proxy classes over IIOP? The com.j2fe.general.HibernateFacade-interface is available on client side and can be loaded by the application class loader (which is an Eclipse application).
The strange thing is that it's possible to do a Class.forName with that class immediately before and after the EJB-call which should get that proxy class from the server.

Interactive report performance problem over database link

Hi gurus,
I have an interactive report that retrieves values from two joined tables both placed on the same remote database. It takes 45 seconds to populate (refresh) a page after issuing a search. If I catch the actual select that is generated by apex ( the one with count(*) over ()...) and run it from sql environment, it takes 1 or 2 seconds. What on earth does consume the rest of the time and how to speed this up? I would like to awoid creating and maintaining local materialized views if possible.
Regards
Samo

Hi
APEX normally needs to return the full result set for the purposes of pagination (where you have it set to something along the lines of show x-y of z), changing this or the max row count can affect performance greatly.
The driving site hint would need to refer to the name of the view, but can be a bit temperamental with this kind of thing. The materialize hint only works for sub-factored queries (in a 'WITH blah AS(SELECT /*+ MATERIALIZE */ * FROM etc. etc.)). They tend to materialize anyway and its best not to use hints like that for production code unless there is absolutely no other option, but just sub factoring without hints can often have a profound effect on performance. For instance
WITH a AS
SELECT c1,
        c2,
        c3,
        c4,
        c5
FROM schema1.view1)
, b AS
SELECT c1,
        c2,
        c3
FROM schema1.view2)
SELECT *
FROM a, b
WHERE a.c5 = b.c3May produce a different plan or even just sub factoring one of the external tables may have an effect.
You need to try things out here and experiment and keep looking at the execution plans. You should also change Toads row fetch setting to be all 9's to get a real idea of performance.
Let me know how you get on.
Cheers
Ben

Iphone 5 video playback problems over quicktime?

ive recently got a new laptop, pre windows 8, and downloaded quicktime pro in order to play my iphone videos right side up because windows media player will play them upside down alot of the time. something i immeadiately noticed was that all my videos from my iphone 5, when played back via quicktime, have a big judder/skip in them every 2 seconds whereis all my iphone 4 videos playback no problem. the few videos i have that are recorded right side up from my iphone 5, because of orientation of the phone during recording, play perfectly fine on windows media player so this this leads me to believe it is a quicktime issue. i have updated to the latest quicktime just a few days ago with hopes of it being corrected but no such luck. im curious if anyone else is having this same problem or knows a fix? also if anyone knows how to flip videos with quicktime so i can just watch them on windows media would be great also. i found a write up how to do it but everytime i try it, after i save it it just reverts back to its orgional orientation. thanks for any help, Jamie

Add me to the list of people having this problem.
I'm running Macbook on 10.5.8. Quicktime is 7.6.9, in case this has any bearing on things.
OK......I just searched a few places and came up with this:
http://en.wikipedia.org/wiki/Perian
It's called Perian, and it's one of a few different options you could use to solve this problem....I just installed it (free), and now the videos play without a hitch. It's a plug-in for Quicktime. There are others that can supposedly do the same thing--look around and give it a shot.
(Also, supposedly this Perian is no longer in open development, and may not work with the newest Quicktime update for the newest Macs, but, like I said, there are other options out there that may work for you instead.)
I have a feeling my problem may have been due to my particular Quicktime/Macbook setup being a bit outdated, but who knows?
Good luck!

Bytes problem over RS232

Hello!
I'm trying to send data between to computer using RS232.
The problem I encounter is the following:
when I send data from 0 to 127 they are well received.
from 128 to 160 they are bad received (actually 130 is received as 8218, 131 as 405, 135 as 8225).
from 160 to 255 they are well received.
I know that bytes in Java are from -128 to +127 and I could understand that number greater than 127 have problems to be transmitted, but because of those 160 to 255 numbers that are well received, I don't get it.
I tried to find a pattern with the association of number sent and received between 128 and 160 but I didn't find anything relevant...
I'm using a simple RS232 cable via an USB to RS232 converter on my computer (I don't have any serial port) while the other computer is directly using its RS232 port.
The port is configured to send data to 9,6kbps, no parity bits, 1 stop bit and 8 data bits.
Has anyone any idea of where my problem could come from?
I get really confused with that...
By the way, if some admins wants to put my post somewhere else because here is not the appropriate place, I totally understand it but could he (or she?) just mail to tell me where it has been put, because last time I posted I didn't find it anymore... lol
Thanks ;)

Please help me!
finally I cannot even write a conversion algorithm because different values return the same value (sounds odd but here it is:)
Send Receive
127 127
128     8364
129     65533

157     65533
158     382
159     376
160 160
As you can see for example 143 and 144 both return 65533...
What can I do?

Service-Type problem on WLC5508 + Freeradius

Hi all,
I'm trying to set up the Management Auth process on my WLC5508 using a Freeradius/Ldap Server.
Auth process through Web management console is working fine except the fact all users are affected in the "Monitor" role.
I have set up the Service-Type attribut to Administrative in my LDAP Server, but the radius server log me the following error :
Thu Oct 20 10:04:41 2011 : Error:   [ldap] Failed to create the pair: Unknown value Administrative for attribute Service-Type
Thu Oct 20 10:04:41 2011 : Auth: Login OK: [test/test] (from client IBL-WLC port 0)
In the ldap.attrs file on my radius server I have the following associations :
replyItem       Service-Type                    radiusServiceType
replyItem       Tunnel-Type                     radiusTunnelType
replyItem       Tunnel-Medium-Type         radiusTunnelMediumType
replyItem       Tunnel-Private-Group-Id     radiusTunnelPrivateGroupId
Note that Freeradius/Ldap configuration work fine for authenticating wireless clients.
If someone could help me, It would be great
Thanks

Extremely old ticket, but I had the same issue so here is the solution I found:
Service-Type needs to be "Administrative-User" (See RFC 2865 and check what your FreeRadius dictionary is using).
wolverine       Auth-Type := LDAP, Huntgroup-Name == "wifi"
                     Cisco-AVPair += "NCS:virtual-domain0=ROOT-DOMAIN",
                     Cisco-AVPair += "NCS:role0=Root",
                     Service-Type = Administrative-User,
                     Fall-Through = Yes
Service-Type = Administrative-User gives admin to WLC.
The 2 Cisco-AVPair grant admin privs to Prime.
