WLC Error - SSID connection is flapping
Hi All,
I have a strange and "simple" scenario which is making problems on my wireless connections, lemme explain:
I have two WLC 5508 running a image version 7.6.100.0 and APs 2602E in 3 different place such as Controller + 13 APs on HQ and 9 APs divided by 2 branches.
I do not have VLANs for while, just a basic and flat vlan, two SSIDs without broadcast which one is for Data Collectors and other is for users with WPA2-Personal security.
APs in HQ are configured as Local Mode and on branches are configured as FlexConnect.
I am losing my connection from Data Collectors or Laptops to the SSIDs (it's just desappearing and returning after 60 seconds +/-). When I look to the WLC log, its showing the errors below:
*spamApTask0: Sep 23 12:16:24.149: #APF-3-WLAN_OUT_OF_RANGE: apf_site_override.c:2309 WLAN value 17 is out of range.
*spamApTask0: Sep 23 12:16:24.149: #LWAPP-3-VENDOR_SPEC_ERR: spam_lrad.c:13403 The system has failed decoding vendor specific payload
*spamApTask0: Sep 23 12:16:21.650: #CAPWAP-3-SEM_RELEASE_ERR: capwap_ac_db.c:107 The system could not release exclusive access of AP entry for 18:9c:5d:44:4e:d0 in the database
Could you please guys help me on this? Could be an Image problem?
I know that my current topology is wrong however it was the only way that I had to put it up regarding business needs.
Thank you guys
Hi Rasika,
It's seems better now, however 40 minutes ago I got the same issue with aditional log. I don't know if it happened due to problem not solved or maybe a problem with one client only. Follow log:

I pinged 3 devices from yesterday (after full upgrade) to today morning and there were ANY downtime. After I back to the office I tried to ping everything and only once it happens as I mentioned above.

Creating new Data Source Error - Database connection Failed
Successfully installed and configured 11.1.1.3.0. Planning and Essbase dev.
Went to Workspace > Administer > Classing Planning Administration > Manage Data Sources > Create Data Source.
Entered all info about the application database , etc. Getting error "The database connection failed" (I was able to connect with no problem during the install)
SQL server 2005 is on the same physical server.
The diagnostic tool shows database connection passed for planning. A new database was created for the new application.
The server event viewer shows these errors.
"Login failed for user 'xxx-hyperion'. The user is not associated with a trusted SQL Server connection."
Group Policy Error "The client-side extension could not apply computer policy settings for 'Default Domain Policy {xxx}' because it failed with error code '0x80070003 The system cannot find the path specified.' See trace file for more details. "
The Group Policy client-side extension Group Policy Services failed to execute. Please look for any errors reported earlier by that extension.
Any help is appreciated.Datasource for the application.
I have created a sql db for this planning application (my datasource). See my first message for more details.
When you create a new planning application, you need to associate it with a data source. Since this is a new install, I don't have any data sources available yet.
So, "To create, edit or delete data sources, click Manage Data Source."
This page lets you validate your connection to the database and essbase server. My essbase server connection validates! The database connection does not validate after I enter all the relevant information.

So it does not let me create a data source for my new planning application, so I cannot create a new planning application.

I have to upload a scanned receipt to a website and I get the error message "connection was reset". I have uploaded these receipt for two years and last week I have had to use another browser to complete this operation. I connect to the website and do the report I must do, but I can no longer upload to this site.
Are you using any additional software for the uploading?
Try using Firefox in [[safe mode]] when you upload. There is no need to make changes when you see the option. Disable all plugins whilst in safe mode. Then try the uploads.
You mention [/questions/921993 elsethread] that it is a work site. Have you contacted your IT department. One possibility is that the site is not recognising Firefox 10.
(One temporary workaround and troubleshhooting test would be to install Firefox3.6.27 [http://portableapps.com/news/2012-02-01_-_firefox_portable_3.6.26_released portable] as an additional browser and try that.) -
I love iTap Mobile. Paid for the app. Sorry to see them discontinue it, but now I know why. Microsoft bought them out! But even though free, I am getting an error: RPC Error: Your connection was denied because of a Resource Access
Policy (TS_RAP). Please contact your server administrator. (2147965402). I worked with iTap to fix this so I guess they sold Microsoft their older buggy code... Microsoft, please fix!
PS: This is the Android version. Mac and iOS are both okay.
EDIT: After an update a few months ago, iOS is no longer working. Not sure if the problem is related to the Android MSRDP issue.
UPDATE - Relevant posts (need Android RDP software engineer to fix):
Event Viewer Log when using Android client:
The user
"DOMAIN\testuser", on client computer "10.x.x.x", met connection authorization policy requirements and was therefore authorized to access the RD Gateway server. The following authentication method was used: "NTLM". (This
is most likely for logging into RD Web - icons shows up).
The
user "DOMAIN\testuser", on client computer "10.x.x.x", did not meet resource authorization policy requirements and was therefore not authorized to resource"localhost".
The following error occurred: "23002". (This is after clicking on any
of the icons).
I
think the Android MS RDP client is providing the incorrect resource. It shouldn't be "localhost".
It should be the RD Connection Broker's hostname, I believe.
Here's what it should look like (connected using a Windows PC going
through the RD Web portal via Internet Explorer):
The user "DOMAIN\testuser", on client computer "10.x.x.x", met connection
authorization policy requirements and was therefore authorized to access the RD Gateway server. The following authentication method was used: "NTLM".
The user "DOMAIN\testuser", on client computer "10.x.x.x", met resource
authorization policy requirements and was therefore authorized to connect to resource "rdsfarm.domain.com".
The user "DOMAIN\testuser", on client computer "10.x.x.x", connected
to resource "rdsfarm.domain.com".
Stephan,
Do you have any way to contact the software engineer who worked on the Android version of the RDP client? Please
have them read this thread. They need to fix the hard coded "localhost" resource to be a variable (namely whatever the user put in for the server).
This is why the MS RDP app is failing in situations where the FQDN for the RD Gateway and Connection Broker uses
the same host name.
Again, this is not a configuration problem on our end as it works as intended with the native Windows RDP client
as well as the Mac and iOS version of the mobile RDP client (all based on iTap Mobile's RDP app).
This is a problem specific to the Android RDP app.
PS: No matter how hard I try, the WYSIWYG editor is not very WYSIWYG at all, and so everything here looks messed up even though it looked right when I posted it (it is deleting new blank lines I'm inserting to make it spaced out and easier to read). See
below to read the post in context.Thanks for the bumps, everyone. I haven't check this thread in a while because I basically gave up on Microsoft's ability to respond. Unlike paid apps, there's no number to call or ticket to open when an app like this malfunctions.
Just to give you an update, iOS users started having issues connecting a few months ago. I don't remember what version started this. I'm not sure if it's the same problem.
Also, the newest version now gives a slightly different error message: RpcOverHttpEndpointException: 2, Your connection was denied because of a Resource Access Policy (TS_RAP). Please contact your server administrator.
For Android users, I am starting to recommend Xtralogic Remote Desktop Client. It's a paid app, but it works great. I don't know of any alternative for iOS.
MSRDP for Mac OSX (was also an iTap application) continues to work throughout the many updates.
We need a software engineer from MS to read my first post. All the information that will point to a fix is there. I strongly believe someone hardcoded the string "localhost" instead of using a variable to point to the FQDN of the rdsfarm
name.
Here's that info again (copied/pasted). It doesn't take an engineer to understand the issue. If you know how to decipher Event Logs, you can see where the problem is.

Outlook 2013 error: The connection to Microsoft Exchange is unavailable
Environment: Windows 7 Enterprise
Setup: Fresh install of Office 2013
Issue: When I launch Outlook I get the error:
The connection to Microsoft Exchange is unavailable. Outlook must be online or connected to complete this action.
Steps to resolve:
I made sure my server name and mail address were correct but this did not have an impact.
I am at a total loss on how to resolve this issue, is there anyway to manually connect to M.E> as it is just saying the connection is unavailable. All of the other threads dealing with this issue have been no help. I can sign into my account
at login.microsoftonline.net so i know the account is valid. I also receive email to my iPhone with the account and server. Any advice would be wonderful.
Now when I start up the application it tells me the same error and brings up something to alter the server and connection address.Hi,
Have you tried to recreate a new mail profile and then test the issue?
To do this, please exit Outlook, and then go to
Control Panel >Mail... > Add…
Details about create a new mail profile, see:
http://support.microsoft.com/kb/829918/en-us
Also, you can try with this KB:
http://support.microsoft.com/kb/2264398
This issue occurs when the
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\User Shell Folders registry key does not contain all of the required data. Specifically, these problems occur if the
AppData string value is missing from this registry key.
To resolve this issue, import the
User Shell Folders registry key from a working Windows User Profile.
Hope this helps.

Message "Error in connection:No result set, result attempts = 100" on VC
Hi,
I am using a JDBC datasource to retrieve, update, insert and delete information from a SQL Server database using executing store procedures from VC.
The selection of the data is perfect but for the deletion, insert or update of any data using store procedures I always get the following message:
"Error in connection:No result set, result attempts = 100"
At the end the information is modified in the database but I get error.
Here is an example of one of my store procedure:
CREATE PROCEDURE [dbo].[DelData]
@id uniqueidentifier
-- Add the parameters for the stored procedure here
AS
BEGIN
-- SET NOCOUNT ON added to prevent extra result sets from
-- interfering with SELECT statements.
SET NOCOUNT ON;
-- Insert statements for procedure here
delete from data
WHERE Rowid=@id;
END
Let me know if somebody knows the reason of this and if there is something that I am doing wrong.
Thanks,
ZarehHi,
when you SELECT data, you get a result. So your connection gets a result set. When you DELETE, INSERT,... you have no result, because you didn't select data. So your connection can't get any result sets.
best regards,

Hi,
I have installed Oracle Workflow Builder 2.6.3 recently on my system and after installation, when I am trying to connect the workflow builder (using database username/password of that particular instance), it is throwing me the following error:
220: Unable to set NLS_LANGUAGE.
210: Oracle Error: ORA-01403: no data found
. SQL text: SELECT NLS_LANGUAGE FROM WF_LANGUAGES WHERE :l IN (NLS_LANGUAGE, CODE)
In the previous threads when I searched for the same issue, I found that if
select value from v$nls_parameters
where parameter='NLS_CHARACTERSET';
returns the value other then WE8ISO8859P1 then that is what I should change my NLS_LANG entry for the builder - i.e. AMERICAN_AMERICA.<character set>.
But I am not getting where should I change NLS_LANG, it is located where...some file? I am new to Workflow.
Please help me. I tried a lot. Any type of help will be highly appreciated.
Thanks,
SumirThis issue (and solution) is described in ML Doc 577905.1 (Error While Connecting To Database Via Workflow Builder)

Installing Java Dialog Instance - Error while connecting to DB
We would like to add a dialog instance to our production Portal server. We installed Portal as stand-alone on the central instance. We have another server we would like to setup to serve as a Portal dialog instance.
So far I have installed Windows 2003 Server Standard. Installed MSSQL server client tools (database is mssql server). Installed jdk 1.4.62. Set java home and path environmental variables. I'm now installing the Java dialog instance (I can't find any documentation on this). From Netweaver installation CD> SAP NetWeaver '04 Support Release 1> Java System> MS SQL Server> Dialog Instance Installation>
SAP System ID: (sid) ES2
Central Host: SAPEPS02
Path to JAVA DVD supplied> JDK Directory confirmed> Domain paramaters confirmed> domain<sid> account passwords supplied> domain<service><sid> account password supplied> Instance number confirmed>
Installation started> It gets to step 8 and fails stating "Error while connecting to DB". I looked through all the log files and couldn't come up with anything (i'm very thorough).
I tried adding the users to the database as dbowners (no luck). I installed SQL server 2000 with SP4. No where during this installation did I get prompted for database parameters?
Is there something basic i'm missing? Does this scenario not work? Any help would be greatly appreciated. Pointing me in the right direction of the correct documentation would also be appreciated. Thank you in advance.
Sincerely,
Brad DridiHi Brad,
I am facing the same problem. I hope by now you must have got the solution for this.
Can you please let me know how did you overcome this situation?
Thank you!!

Error while Connecting report Best Practices v1.31 with SAP
Hello experts,
I'm facing an issue while trying to connect some of my reports from Best Practices for BI with SAP.
It only happens when it's about info sets, the other ones that are with SAP tables go smoothly without a problem.
The most interesting is I have already one of the reports connected to SAP info sets.
I have already verified the document of steps of creation of additional database that comes with BP pack. They seem ok.
Here goes what Crystal Reports throws to me after changing the data source to SAP:
For report "GL Statement" one of the Financial Analysis one which uses InfoSet: /KYK/IS_FIGL_I3:
- Failed to retrieve data from the database; - click ok then...
- Database connector error: It wasn't indicated any variant for exercise (something like this after translating) - click ok then
- Database connector error: RFC_INVALID_HANDLE
For report "Cost Analysis: Planned vs. Actual Order Costs" one of the Financial Analysis one which uses InfoSet: ZBPBI131_INFO_ODVR and ZBPBI131_INFO_COAS; and also the Query CO_OM_OP_20_Q1:
- Failed to retrieve data from the database; - click ok then...
- Database connector error: check class for selections raised errors - click ok then
- Database connector error: RFC_INVALID_HANDLE
Obs.: Those "Z" infosets are already created in SAP environment.
The one that works fine is one of the Purchasing Analysis reports:
- Purchasing Group Analysis -> InfoSet: /KYK/IS_MCE1
I'm kind of lost to solve this, because I'm not sure if it can be in the SAP JCO or some parameter that was done wrongly in SAP and I have already check possible solutions for both.
Thanks in advance,
Carlos Henrique Matos da Silva - SAP BusinessObjects BI - Brazil.I re-checked step 3.2.3 - Uploading Crystal User Roles (transaction PFCG) - of the manual where it talks about CRYSTAL_ENTITLEMENT and CRYSTAL_DESIGNER roles, I noticed in the Authorizations tab that the status was saying it hadn't been generated and I had a yellow sign, so then that was what I did (I generated) as it says in the manual.
Both statuses are now saying "Authorization profile is generated" and the sign is now green on the tab.
I had another issue in the User tab (it was yellow as Authorizations one before generating)....all I needed to do to change to green was comparing user (User Comparison button).
After all that, I tried once more to refresh the Crystal report and I still have the error messages being thrown.
There's one more issue in one of the tabs of PFCG transaction, it is on the Menu one where it is with a red sign, but there's nothing talking about it in the manual. I just have a folder called "Role menu" without anything in it.
Can it be the reason why I'm facing errors when connecting the report to SAP infoSets? (remember one of my reports which is connected to an infoSet works good)
Thanks in advance,

fixed the issue and "JdbcCheckup" passed.
