When roaming from AP to AP - is reassociation supported?

When roaming from Apple Express access point to another Apple Express access point - is reassociation supported? How about in other Apple access point models?
I realize that this is not defined in 802.11 and therefore is vendor implementaiton dependant in the access point, and that most SOHO level access points do not support reassociation - whereas enterprise level products (Cisco, etc.) do support the capability.
Thanks

No, reassociation does not require a RADIUS server. Cisco's Fast Reassociation is an advanced reassociation feature than does interact with a RADIUS server.
The feature I am asking of occurs when a client roams from AP1 to AP2, a reassociation (rather than a standard reassociation request) occurs from the client to AP2. AP2 then, over the wire, goes to AP1 and picks up any buffered data for the client and passes it to the client. This enables a better roaming experience by ensuring buffered data is not lost or have to be resent/retried by a upper layer protocol.
As I said, the inter AP communication portion of this is not defined by 802.11 and is vendor implementation specific - if implemented at all. I am wanting to know if any Apple Airport access points have this capability implemented.

  • Connectivity loss when roaming from AP to AP

    I work for a healthcare organization where nurses use what we refer to as COWS, or carts on wheels. These carts are basically laptops attached to carts that utilize our wireless infrastructure to access patient care applications.
    The problem we've been having and working with the application developers on is that, whenever the carts are moved between patient rooms and have to associate with a different AP, the telnet connection that the application uses to establish connectivity is dropped during the short delay in the changeover.
    Anyone have any experience with settings that might mitigate this? Far as I know there are no telnet timers that can be adjusted(buffered) to help with this situation, and I'm not certain if anything can be adjusted on the wireless network to help. The "fix" has been to have the user reboot to re-establish the telnet session and then everything's good again.
    Any suggestions on things to try?
    Thanks.

    I assume these are all on the same SSID and same subnet, i.e. there are no layer 3 roaming issues since you did not mention if you use LWAPP APs. In any case I used to roam all the time with telnet sessions to Cisco switches. If it is dropping the session, it is more likely because of the host system. You could test that by testing to a Cisco device.
    A couple of suggestions:
    1. Use WPA2 instead of WPA. WPA2 handles roaming better.
    2. If you are using XP wireless make sure you have the Microsoft WPA2 update installed. Not necessary if you use another wireless supplicant.
    3. Test roaming with a laptop from room to room. If you are loosing more than two pings or so, your roaming sensitivity is not working optimally. Use continuous pings.
    4. You could go to fast roaming using CCKM; however, I would make sure the standard roaming method is working correctly before going to the effort of changing everything. Besides, you will need to have a wireless client capable of CCKM. If not, you are out of luck. I had that problem with some of my Windows CE devices. They were too dumb to use CCKM.
    5. I did have some Windows CE devices which did not roam properly until I had the roaming sensivity set. I was loosing about 7 pings. This is not normal unless you have a problem.
    6. Last resort - but expensive. We had an intermediate server that would hold sessions to SAP due to the potential of the same problem you have. The company that provided it to us was Psion Teklogix. It prevented session loss because a server held the session, not the mobile client. A company like this one should be able to modify the application to your needs if you have money to spend.
    Testing is the key I think, but WPA2 would have to help due to the caching of authentications. If you go back to a room you were just in, it should roam faster.

  • "Lightroom encountered and error when reading from its preview cache and needs to quit"

    I keep receiving this error every time I open LR, "Lightroom encountered and error when reading from its preview cache and needs to quit" and the app won't open. It said LR would try and fix this error next time I opened it but the error remains. I tried uninstalled and installing the app and the error remains.
    Any Ideas here? Is there another app that may be telling it where to look for the cache and it no longer there? I was using a ramdisk for a bit but ditched it. Not sure if that has something to do with it but it seems suspect.
    Your thoughts?

  • Wireless Client Authentication issues when roaming Access Points (Local)

    I have a Cisco 5508 with Software version 7.4.121.0 and Field Recovery 7.6.101.1.
    There are a handful of clients that when roaming between AP's with the same SSID that get an authentication issue and have to restart the wireless to get back on.
    From Cisco ISE
    Event
    5400 Authentication failed
    Failure Reason
    11514 Unexpectedly received empty TLS message; treating as a rejection by the client
    Resolution
    Ensure that the client's supplicant does not have any known compatibility issues and that it is properly configured. Also ensure that the ISE server certificate is trusted by the client, by configuring the supplicant with the CA certificate that signed the ISE server certificate. It is strongly recommended to not disable the server certificate validation on the client!
    Root cause
    While trying to negotiate a TLS handshake with the client, ISE expected to receive a non-empty TLS message or TLS alert message, but instead received an empty TLS message. This could be due to an inconformity in the implementation of the protocol between ISE and the supplicant. For example, it is a known issue that the XP supplicant sends an empty TLS message instead of a non-empty TLS alert message. It might also involve the supplicant not trusting the ISE server certificate for some reason. ISE treated the unexpected message as a sign that the client rejected the tunnel establishment.
    I am having a hard time figuring out what is causing this. My assumption is if there were a problem with the Controller or AP configurations then it would happen to everyone. My further assumption is if the client had a problem with their laptop (windows 7) then why does work at other times? So I have checked and the ISE certificate is trusted by client.
    Is something happening that the previous access point is holding on to the mac and the return authentication traffic is going to the old AP instead of the new one or something like that which is corrupting the data?
    I also had this from Splunk for the same client:
    Mar 5 13:44:51 usstlz-piseps01 CISE_Failed_Attempts 0014809622 1 0 2015-03-05 13:44:51.952 +00:00 0865003824 5435 NOTICE RADIUS: NAS conducted several failed authentications of the same scenario
     FailureReason="12929 NAS sends RADIUS accounting update messages too frequently"
    Any help on this would be appreciated. These error messages give me an idea but doesn't give me the exact answer to why the problem occurred and what needs to be done to fix it.
    Thanks

  • Data Services setting - 'Off When Roaming'

    Does anyone know if it is possible to lock the 'Data Services' setting under 'Mobile Network Options' to 'Off When Roaming' WITHOUT the use of a BES?

    sdgardne,
    I think he wants to BES lock it so NO-ONE can change it, at least without permision from their BES Admin, Managing director otr fomr the Carrier.
    Even with a BES, there is no setting to lock that permenantly.
    (Unless one of you good BB people can find it in the OTY Policy ref document for 4.x or 5.0 BES - I cant fin anything to lock it!)

  • GPS on 929 when roaming

    I find that the map only finds my location when abroad if I enable data roaming. I thought the whole point of having th downloadable maps was that you didn't need to use data when roaming. I have location services enabled and it works fine in my home country, the UK or when on wifi or when I enable data roaming. Is there anything else that I should do?

    To clarify.  I have now twice roamed with my 920 and the only way that it locates me on the map (which I had pre-downloaded for both countries before departure) was when I was on wifi or had data roaming enabled for over the air reception.  From the reply I received it suggested that it would eventually find my location without enabling roaming, but does anyone have any idea how long this will take - and will the battery still be alive by then?
    In contrast when roaming with my old iPhone 4S, using a Tom-Tom app, I did'nt have to enable data roaming and it worked very well.  I was hoping that the 920 would be at least as good as this.

  • ActiveSync issue when roaming

    So far we had five users with BB Z10 and Q10 who were traveling internationally have experienced issue while accessing email. All the users were setup via Active Sync for corporate emails. Once they land to their final destination which has been China, Australia and Colombia. They will receive 4G or 4g connectivity but no emails. They will be receive their personal emails like gmail, yahoo, etc but no corporate emails. It will take about 20 minutes before they start seeing corporate emails. After about an hour or so the device will stop receiving emails. The only fix is to manually remove email corporate email account and re-add it on the device. Once we are resetup the account then everything works normal throughout their stay.  We are running exch 2007. Z10s are running 10.1.0.2006 build and we are on T-Mobile network. Has anyone experience similar issue ?
    Thanks,
    Bhavik

    Hello Bhaviksom, 
    Have a look at the 2 possible causes to this issue along with the 2 possible resolutions. 
    Cause 1
    The Microsoft Exchange ActiveSync Mailbox policy has the value "Allow Direct Push when roaming" set to no
    Cause 2
    The email profile assigned to the BlackBerry smartphone in the BlackBerry Device Service has the value "Manual Sync while Roaming" set to yes
    Resolution 1
    There are two ways to resolve cause one:
    One the BlackBerry smartphone select the settings icon from the home screen
    Select Accounts
    Select the Microsoft Exchange ActiveSync account
    Select Advanced
    Toggle the option for Push off and back on again.
    To avoid all BlackBerry smartphones having to sync manually while roaming, the option will need to be changed in the ActiveSync Mailbox policy on the Microsoft Exchange Server. To perform the action do the following:
    Open the Exchange Management Console
    In the console tree, navigate to Organization Configuration > Client Access
    In the result pane, click the Exchange ActiveSync Mailbox Policies tab, and then select the policy you want to view or configure
    In the action pane, click Properties
    Select the Sync Settings tab
    Change the value for Allow Direct Push when roaming to Yes
    Resolution 2
    If the BlackBerry smartphone has an email profile which is pushed from the BlackBerry Device Service the option "Manual Sync while Roaming" will need to be changed to "No" in the email profile which is assigned to the BlackBerry smartphone.
    Open the BlackBerry Administration console for BlackBerry Device Service
    Expand Email profiles under BlackBerry Solution management
    Select Manage email profiles under Email profiles
    Select the profile and click Edit profile
    Change the option "Manual Sync when roaming" to no
    Let us know if this helps. Have a good day..

  • What functions work and don't work when roaming?

    I was out of town on the weekend, and I had to use roaming. Now, I was finding that sometimes my Blackberry Internet Service was available and sometimes it wasn't. What was most puzzling was that sometime the web-browser would work without BIS available, and sometimes it wouldn't. It seemed to do both depending on time of day from the same location. I have a little weather applet in my Blackberry Bold, and again it was sometimes working, and sometimes it wasn't.
    It was all pretty puzzling, what's the real answer here? Do Internet-based apps work or don't they when there's regular cellular data services available, but not BIS?

    Hi bbb167,
    Your provider will best be able to answer any questions on what services are available when roaming. Some internet based applications may require a BlackBerry Internet Service connection to function and some may be able to use your carrier's browser or a Wi-Fi connection. You may want to check with each vendor for the connection requirements of their application.

  • PL/SQL procedure is 10x slower when running from weblogic

    Hi everyone,
    we've developed a PL/SQL procedure performing reporting - the original solution was written in Java but due to performance problems we've decided to switch this particular piece to PL/SQL. Everything works fine as long as we execute the procedure from SQL Developer - the batch processing 20000 items finishes in about 80 seconds, which is a serious improvement compared to the previous solution.
    But once we call the very same procedure (on exactly the same data) from weblogic, the performance seriously drops - instead of 80 seconds it suddenly runs for about 23 minutes, which is 10x slower. And we don't know why this happens :-(
    We've profiled the procedure (in both environments) using DBMS_PROFILER, and we've found that if the procedure is executed from Weblogic, one of the SQL statements runs noticeably slower and consumes about 800 seconds (90% of the total run time) instead of 0.9 second (2% of the total run time), but we're not sure why - in both cases this query is executed 32742-times, giving 24ms vs. 0.03ms in average.
    The SQL is
    SELECT personId INTO v_personId FROM (            
            SELECT personId FROM PersonRelations
            WHERE extPersonId LIKE v_person_prefix || '%'
    ) WHERE rownum = 1;Basically it returns an ID of the person according to some external ID (or the prefix of the ID). I do understand why this query might be a performance problem (LIKE operator etc.), but I don't understand why this runs quite fast when executed from SQL Developer and 10x slower when executed from Weblogic (exactly the same data, etc.).
    Ve're using Oracle 10gR2 with Weblogic 10, running on a separate machine - there are no other intensive tasks, so there's nothing that could interfere with the oracle process. According to the 'top' command, the wait time is below 0.5%, so there should be no serious I/O problems. We've even checked JDBC connection pool settings in Weblogic, but I doubt this issue is related to JDBC (and everything looks fine anyway). The statistics are fresh and the results are quite consistent.
    Edited by: user6510516 on 17.7.2009 13:46

    The setup is quite simple - the database is running on a dedicated database server (development only). Generally there are no 'intensive' tasks running on this machine, especially not when the procedure I'm talking about was executed. The application server (weblogic 10) is running on different machine so it does not interfere with the database (in this case it was my own workstation).
    No, the procedure is not called 20000x - we have a table with batch of records we need to process, with a given flag (say processed=0). The procedure reads them using a cursor and processes the records one-by-one. By 'processing' I mean computing some sums, updating other table, etc. and finally switching the record to processed=1. I.e. the procedure looks like this:
    CREATE PROCEDURE process_records IS
        v_record records_to_process%ROWTYPE;
    BEGIN
         OPEN records_to_process;
         LOOP
              FETCH records_to_process INTO v_record;
              EXIT WHEN records_to_process%NOTFOUND;
              -- process the record (update table A, insert a record into B, delete from C, query table D ....)
              -- and finally mark the row as 'processed=1'
         END LOOP;
         CLOSE records_to_process;
    END process_records;The procedure is actually part of a package and the cursor 'records_to_process' is defined in the body. One of the queries executed in the procedure is the SELECT mentioned above (the one that jumps from 2% to 90%).
    So the only thing we actually do in Weblogic is
    CallableStatement cstmt = connection.prepareCall("{call ProcessPkg.process_records}");
    cstmt.execute();and that's it - there is only one call to the JDBC, so the network overhead shouldn't be a problem.
    There are 20000 rows we use for testing - we just update them to 'processed=0' (and clear some of the other tables). So actually each run uses exactly the same data, same code paths and produces the very same results. Yet when executed from SQL developer it takes 80 seconds and when executed from Weblogic it takes 800 seconds :-(
    The only difference I've just noticed is that when using SQL Developer, we're using PL/SQL notation, i.e. "BEGIN ProcessPkg.process_records; END;" instead of "{call }" but I guess that's irrelevant. And yet another difference - weblogic uses JDBC from 10gR2, while the SQL Developer is bundled with JDBC from 11g.

  • Opening Excel Workbook Fails when run from Scheduled Task on Windows Server 2008 Rw

    Hi,
    I have a little vbs script that instantiates the Excel.Application object and then opens a work book to perform some tasks on it. The script runs fine when run from the command line. When I attempt to run it as a scheduled task (it is supposed to update
    data that is pulled from a SQL Server at regular intervals), it fails with the following error:
    Microsoft Office Excel cannot access the file 'c:\test\SampleWorkbook.xlsm'. There are several possible reasons: .....
    The file does exist. The path reported in the error is correct. The account under which the task is running is the same account I use to run it from the command line. User Account Control is not enabled, and the task is set up to run with highest privileges.
    When I run the same script through the Task Scheduler from a Windows Server 2003 machine, it works without issue.
    I was just wondering if somebody on this forum has run into a similar issue in connection with Windows Server 2008 R2 and figured out what the magic trick is to make it work. I'm sure it is rights related, but I haven't quite figured out what which rights
    are missing.
    Thanks in advance for any advice you may have.

    This is truly killing me ... trying to get it working on Windows Server 2012 without success.
    I desperately need to automate running Excel macros in a "headless" environment, that is non-interactive, non-GUI, etc.
    I can get it to work using Excel.Application COM, either via VBScript or Powershell, successfully on many other Windows systems  in our environment - Windows Server 2008 R2, Windows 7 (32-bit), etc.,  -BUT-
    The two servers we built out for running our automation process are Windows Server 2012 (SE) - and it just refuses to run on the 2012 servers - it gives the messages below from VBScript and PowerShell, respectively- 
    I have tried uninstalling and re-installing several different versions of Microsoft Excel (2007 Standard, 2010 Standard, 2010 Professional Plus, 32-bit vs. 64-bit, etc.), but it makes no difference.
    Would be extremely grateful if any one out there has had any success in running Excel automation on Server 2012 in a non-interactive environment that they could share.
    ( I have tried adding the "%windir%\syswow64\config\systemprofile\desktop"
    folder, which did fix the issue for me when testing on Windows Server 2008 R2, but sadly did not resolve it on Windows Server 2012 )

  • Application has problems when migrated from 10g to 11g

    Hi there,
    I am hoping someone can shed some light on a problem I have in moving an application from Oracle 10g to Oracle 11g. The app works fine on 10g (uses Apache webserver with PL/SQL module, and APEX 3.1.2.00.2), but on 11g using the embedded web server and APEX 3.2.0.00.27, it doesnt. Most of the app works fine, but there are a couple of pages that provide the ability to add child rows to a parent/child relationship, where the parameter passing mechanism from one page to the next appears to suffer from some sort of corruption. I have traced this using the "session" and "debug" buttons on the developer interface, which show that the values of the parameters get changed inexplicably, when branching from one page to the next - even when the page is actually branching to itself.
    I am using the "Set these items, "With these values" fields in the branch, and have verified that the correct values are being associated with the correct items in the application builder. But while this does work correctly under 10g, with 11g, the wrong values end up being passed. Just prior to the branch the set of parameters have the correct values, but immediately after the branch, one of the values is NULL, another has the value of a different item, and a third has a totally random value - I have no idea were it comes from!
    I migrated the application from 10g to 11g using the APEX application developer's Export/Import options. There have been no other changes. Should this have worked? If so, any ideas what might have gone wrong?
    Thanks,
    Sid.

    Well, I managed to solve this, but not in a way that makes much sense.
    In desperation (I had tried almost everything else!) I changed the value of "Cached" in the page settings from "No" to "Yes", and ran the app, but the page didnt render correctly (in either Firefox or IE7) - in fact all that displayed was the developers toolbar at the bottom of the page. I changed the value of "Cached" back to "Y", ran the app again, and hey presto - everything worked fine! I actually did this a second time with a fresh import of the app from 10g, just to be sure I wasnt seeing things. I wasnt!
    There was just one further issue - everything worked fine apart from this section of code in a page process:-
    ELSIF (:p9_filter_type = 5) THEN
    IF (:p9_x_gene_list IS NOT NULL) THEN
    :p9_filter := :p9_x_gene_list;
    END IF;
    :p9_entity_types := 'GENE';
    END IF;
    In 11g the value of :p9_entity_types was not being set to 'GENE' when :p9_filter_type was 5. This was (and still is) working in 10g. I changed the code as follows:-
    ELSIF (:p9_filter_type = 5) THEN
    :p9_entity_types := 'GENE';
    IF (:p9_x_gene_list IS NOT NULL) THEN
    :p9_filter := :p9_x_gene_list;
    END IF;
    END IF;
    ... and now it works fine in 11g as well.
    Only wish I knew why!

  • Oracle Server 11.2.0.1.0 64-bit fails when invoked from InstallShield

    I'm trying to install the Oracle Server 11.2.0.1.0 64-bit on Windows 2008 SP1 from the InstallShield 2010.
    The installation is silent. Invoked by command line:
    J:\Oracle_11.2.0_x64\OracleServer_11.2.0.1_x64\setup.exe ORACLE_HOME_NAME="ARAXI_11" -silent -nowelcome -force -nowait -noconsole -loglevel fine -noconfig -ignoreSysPrereqs use_prereq_checker=false -responseFile C:\Oracle\11.2.0\installation\scripts\SVRCUSTOM11.2.0.rsp
    The problem is that when the command is invoked from command line (cmd), the installation is successful.
    However, when the same command is invoked from under the InstallShield, the installation fails on Architecture requirement check:
    INFO: *********************************************
    INFO: Architecture: This is a prerequisite condition to test whether the system has a certified architecture.
    INFO: Severity:CRITICAL

    INFO: Advice is ABORT
    INFO: Adding ExitStatus INVALID_USER_INPUT to the exit status set
    The questions:
    1. Why the requirement checks give different results when installation is invoked from CMD and from InstallShield?
    2. Why the requirement checks are done despite the parameters "-ignoreSysPrereqs" and "use_prereq_checker=false"?
    3. What should I do to get the installation pass (either remove the check or make it satisfying)?
    PS. The 32 bit Oracle Server installation on Windows 2003 works without problem when invoked from InstallShield.

    Please use 2008R2 if you want to install 11gR2 versionThank you for that update. Possibly it will help me to solve another trouble.
    Regarding the problem I described, the issue is that I install Oracle Client 32 bit prior to trying to install Oracle Servier 64 bit.
    The Oracle Client setup had started RemoteExecService.exe 32 bit process. And the process remained running after the installation completed.
    The Oracle Server setup utilizes the running RemoteExecService.exe process. Since the process is 32 bit, the architecture requirement check had failed.
    I've added to my script killing the process
    taskkill /F /IM RemoteExecService.exe
    before invoking the Oracle Server installation.
    That way the Oracle Server setup starts another RemoteExecService.exe process and the new process is 64 bit.
    The architecture requirement succeed.

  • Chinese characters scrambled when loading from DS to BW

    Hi, I've been pulling my hair out with this issue.
    I have a flat file containing Chinese text. When I load this in BW using 'FLATFILE' as a source system, it works fine. BW shows the correct Chinese characters.
    When I do the same load using BODI, I get funny characters.
    When I use BODI to load from one flat file into another flat file, the Chinese characters remain correct.
    What do I need to do to make sure I get the right Chinese characters in BW when loading from BODI?
    BODI is installed on Unix on Oracle 10.
    I run the jobs as batch processes.
    The dsconfig.txt has got:
    AL_Engine=<default>_<default>.<default>
    There are no locale settings in al_env.sh
    BW target is UTF-8 codepage.
    File codepage is BIG5-HKSCS
    BODI is set up as a Unicode system in SAP BW.
    When loading flat file to flat file, I get a message:
    DATAFLOW: The specified locale <eng_gb.iso-8859-1> has been coerced to <Unicode (UTF-16)
    because the datastore <TWIN_FF_CUSTOMER_LOCAL> obtains data in <BIG5-HKSCS> codepage.
    JOB: Initializing transcoder for datastore <TWIN_FF_CUSTOMER_LOCAL> to transcode between
    engine codepage<Unicode (UTF-16)>  and datastore codepage <BIG5-HKSCS>
    When loading to BW the messages are almost the same, but now the last step in UTF-16 to UTF-8.
    I read the wiki post which definitely helped me to understand the rationale behind code page, but now I ran out of ideas what else to check ( http://wiki.sdn.sap.com/wiki/display/BOBJ/Multiple+Codepages )
    Any help would be greatly appreciated.

    Hi all. Thanks for the Inputs. This is what I got when I clicked on the Details Tab of the Monitor....
    Error when transferring data; communication error when analyzing
    Diagnosis
    Data packages or InfoPackages are missing in BI but there were no apparent processing errors in the source system. It is therefore probable that there was an error in the data transfer.
    The analysis tried to read the ALE outbox of the source system. This lead to error .
    It is possible that there is no connection to the source system.
    Procedure
    Check the TRFC overview in the source system.
    Check the connection to the source system for errors and check the authorizations and profiles of the remote user in both the BI and source systems.
    Check th ALE outbox of the source system for IDocs that have not been updated.

    Anybody got this problem

    Hi!
    What kind of RFC do you use? If you use synchronous RFC the caller waits for the answer/result of the called function. In normal cases this should solve your issue.
