Do sapconsole sessions fail over ?

Hello all,
We have users in our warehouse plant using RF Devices and connecting via two sapconsole servers to our R/3 Enterprise system.
There are times when the router on our remote location will failover to an alternate router.  We have noticed that the RF devices tend to hang and take a while to clear. 
The question is when the network connection is failed over to a new router, will active sessions be impacted ?
Does the same hold for normal sapgui sessions ?  It appears our normal SAPGUI users are "less" impacted by this switchover.
Thanks,
Ramesh

Specific to the AP failover. Why dont you deploy AP FALLBACK? When a controller falls offline for
any reason the APs join other controllers. HOWEVER when the controller comes online they will fallback to the controllers
you want with NO intervention from you.
fyi
NoteWhen an access point’s primary controller comes back online, the access point disassociates from the backup controller and reconnects to its primary controller. The access point falls back to its primary controller and not to any secondary controller for which it is configured. For example, if an access point is configured with primary, secondary, and tertiary controllers, it fails over to the tertiary controller when the primary and secondary controllers become unresponsive and waits for the primary controller to come back online so that it can fall back to the primary controller. The access point does not fall back from the tertiary controller to the secondary controller if the secondary controller comes back online; it stays connected to the tertiary controller until the primary controller comes back up.

  • Multiple j-sessions for IOP fail-over?

    Weblogic has the ability to support multiple j-sessions to allow fail-over of the connection.
    My understanding is that this is not currently supported in IOP.
    When will IOP support multiple j-sessions?
    Is it possible to get a patch for this in the current version 11 of IOP?
    Thank you.

    That is part of the product roadmap to support multiple j-sessions for IOP fail over using Weblogic. That way, if the primary IOP server fails, the user can be re-routed to the backup server in a high-availability fashion. However, that is not supported currently, but will be over the next couple of releases.

    Hey Guys here's the what we're dealing with:
    iPhone 4S 64GB running iOS 5.0.1 (Latest)
    Macbook Pro (Late 2008) 15" running Mac OS Lion 10.7.3 (Latest)
    iTunes 10.5.3 (Latest)
    Scenario:
    (Previously unencountered issue until now)
    iPhone plug into Macbook Pro to sync with iTunes AUTOMATICALLY/MANUALLY,
    Sync session stuck on: "Waiting for sync to start"
    Error message: "The iPhone "..." could not be synced because the sync session failed to start"
    Attempted Fix and Known Facts:
    Have tried syncing with iPhone, iPod Touch and iPad with no success
    Wireless syncing no success
    Restarting and Resetting of iTunes, Computer, iPhone with no Success
    Have done a full clean install of iTunes with no success - using Apple Support this guide: http://support.apple.com/kb/HT1747?viewlocale=null&locale=null
    Cannot find AppleMobileDeviceSupport.pkg
    iPod Service Process and Apple Mobile Device Process not running under Activity Monitor
    Please help! I have battled with this problem for over a week!

    I had figured it out that when i unchecked the "sync apps" box, and just sync my videos and music, everything turned out normal.
    Have you jail breaked your iphone ? 
    Oh and I also found another solutions is that you open My Documents\My Music\iTunes, delete the Library.itl file. It will erase all of your apps and music. BUt you can download your stuffs back again.
    Try that. Good luck

  • How Front End pool deals with fail over to keep user state?

         Hello to all, I searched a lot of articles to understand how Lync 2010 keeps user state if a fail happens in a Front Pool node, but didn't find anything clear.
         I found a MS info. about ths topic : " The Front End Servers maintain transient information—such as logged-on state and control information for an IM, Web, or audio/video (A/V) conference—only for the duration of a user’s session.
    This configuration
    is an advantage because in the event of a Front End Server failure, the clients connected to that server can quickly reconnect to another Front End Server that belongs to the same Front End pool. "
        As I read, the client uses DNS to reconnect to another Front End in the pool. When it reconnects to an available server, does he lose what he/she was doing at Lync client? Can the server that is now hosting his section recover all
    "user's session data"? Is positive, how?
       Regards, EEOC.

    The presence information and other dynamic user data is stored in the RTCDYN database on the backend SQL database in a 2010 pool:
    http://blog.insidelync.com/2011/04/the-lync-server-databases/  If you fail over to another pool member, this pool member has access to the same data.
    Ongoing conversations and the like are cached at the workstation.

  • OCR and voting disks on ASM, problems in case of fail-over instances

    Hi everybody
    in case at your site you :
    - have an 11.2 fail-over cluster using Grid Infrastructure (CRS, OCR, voting disks),
    where you have yourself created additional CRS resources to handle single-node db instances,
    their listener, their disks and so on (which are started only on one node at a time,
    can fail from that node and restart to another);
    - have put OCR and voting disks into an ASM diskgroup (as strongly suggested by Oracle);
    then you might have problems (as we had) because you might:
    - reach max number of diskgroups handled by an ASM instance (63 only, above which you get ORA-15068);
    - experiment delays (especially in case of multipath), find fake CRS resources, etc.
    whenever you dismount disks from one node and mount to another;
    So (if both conditions are true) you might be interested in this story,
    then please keep reading on for the boring details.
    One step backward (I'll try to keep it simple).
    Oracle Grid Infrastructure is mainly used by RAC db instances,
    which means that any db you create usually has one instance started on each node,
    and all instances access read / write the same disks from each node.
    So, ASM instance on each node will mount diskgroups in Shared Mode,
    because the same diskgroups are mounted also by other ASM instances on the other nodes.
    ASM instances have a spfile parameter CLUSTER_DATABASE=true (and this parameter implies
    that every diskgroup is mounted in Shared Mode, among other things).
    In this context, it is quite obvious that Oracle strongly recommends to put OCR and voting disks
    inside ASM: this (usually called CRS_DATA) will become diskgroup number 1
    and ASM instances will mount it before CRS starts.
    Then, additional diskgroup will be added by users, for DATA, REDO, FRA etc of each RAC db,
    and will be mounted later when a RAC db instance starts on the specific node.
    In case of fail-over cluster, where instances are not RAC type and there is
    only one instance running (on one of the nodes) at any time for each db, it is different.
    All diskgroups of db instances don't need to be mounted in Shared Mode,
    because they are used by one instance only at a time
    (on the contrary, they should be mounted in Exclusive Mode).
    Yet, if you follow Oracle advice and put OCR and voting inside ASM, then:
    - at installation OUI will start ASM instance on each node with CLUSTER_DATABASE=true;
    - the first diskgroup, which contains OCR and votings, will be mounted Shared Mode;
    - all other diskgroups, used by each db instance, will be mounted Shared Mode, too,
    even if you'll take care that they'll be mounted by one ASM instance at a time.
    At our site, for our three-nodes cluster, this fact has two consequences.
    One conseguence is that we hit ORA-15068 limit (max 63 diskgroups) earlier than expected:
    - none ot the instances on this cluster are Production (only Test, Dev, etc);
    - we planned to have usually 10 instances on each node, each of them with 3 diskgroups (DATA, REDO, FRA),
    so 30 diskgroups each node, for a total of 90 diskgroups (30 instances) on the cluster;
    - in case one node failed, surviving two should get resources of the failing node,
    in the worst case: one node with 60 diskgroups (20 instances), the other one with 30 diskgroups (10 instances)
    - in case two nodes failed, the only node survived should not be able to mount additional diskgroups
    (because of limit of max 63 diskgroup mounted by an ASM instance), so all other would remain unmounted
    and their db instances stopped (they are not Production instances);
    But it didn't worked, since ASM has parameter CLUSTER_DATABASE=true, so you cannot mount 90 diskgroups,
    you can mount 62 globally (once a diskgroup is mounted on one node, it is given a number between 2 and 63,
    and other diskgroups mounted on other nodes cannot reuse that number).
    So as a matter of fact we can mount only 21 diskgroups (about 7 instances) on each node.
    The second conseguence is that, every time our CRS handmade scripts dismount diskgroups
    from one node and mount it to another, there are delays in the range of seconds (especially with multipath).
    Also we found inside CRS log that, whenever we mounted diskgroups (on one node only), then
    behind the scenes were created on the fly additional fake resources
    of type ora*.dg, maybe to accomodate the fact that on other nodes those diskgroups were left unmounted
    (once again, instances are single-node here, and not RAC type).
    That's all.
    Did anyone go into similar problems?
    We opened a SR to Oracle asking about what options do we have here, and we are disappointed by their answer.
    Regards
    Oscar

    Hi Klaas-Jan
    - best practises require that also online redolog files are in a separate diskgroup, in case of ASM logical corruption (we are a little bit paranoid): in case DATA dg gets corrupted, you can restore Full backup plus Archived RedoLog plus Online Redolog (otherwise you will stop at the latest Archived).
    So we have 3 diskgroups for each db instance: DATA, REDO, FRA.
    - in case of fail-over cluster (active-passive), Oracle provide some templates of CRS scripts (in $CRS_HOME/crs/crs/public) that you edit and change at your will, also you might create additionale scripts in case of additional resources you might need (Oracle Agents, backups agent, file systems, monitoring tools, etc)
    About our problem, the only solution is to move OCR and voting disks from ASM and change pfile af all ASM instance (parameter CLUSTER_DATABASE from true to false ).
    Oracle aswers were a litlle bit odd:
    - first they told us to use Grid Standalone (without CRS, OCR, voting at all), but we told them that we needed a Fail-over solution
    - then they told us to use RAC Single Node, which actually has some better features, in csae of planned fail-over it might be able to migreate
    client sessions without causing a reconnect (for SELECTs only, not in case of a running transaction), but we already have a few fail-over cluster, we cannot change them all
    So we plan to move OCR and voting disks into block devices (we think that the other solution, which needs a Shared File System, will take longer).
    Thanks Marko for pointing us to OCFS2 pros / cons.
    We asked Oracle a confirmation that it supported, they said yes but it is discouraged (and also, doesn't work with OUI nor ASMCA).
    Anyway that's the simplest approach, this is a non-Prod cluster, we'll start here and if everthing is fine, after a while we'll do it also on Prod ones.

  • Is Replica aware stubs are in infinite loop when fail over????

              Hi
              Any help on this Appreciated
              See in this senario, where there is four weblogic instance runs in the cluster
              and a replica aware stub(stateless bean with idempodent methods) finds a particular
              method fails on a server and it redircets the request to another one server but the
              same method fails on all the server, then what is goin to happen?? is it going to
              throw some exception or gonna be in a loop to keep on redirecting the method request
              to all servers in Round???
              Regards
              Aruna
              

              Aruna,
              A stateless session bean whose methods have been declared idempotent will automatically
              retry on another service provider in a fail-over situation. When a fail-over situation
              occurs, the stub refreshes its list of service providers. Note: Just because your
              method call fails, doesn't mean it's a fail-over situation.

    yes that is right.
    Essentially you should be doing one of the following on weblogic side:
    1) Installed Certs on weblogic that were obtained from a commercial CA. (like verisign, thawte etc)
    In this case, you will receive rootCA crt along with the other bundled certs and private key.
    these rootCA certs are publicly available (your browser will be already using them)
    2) Using certs signed by your company. (companies can maintain their own CA)
    In this case you should be having a rootCA cert from your company.
    3) using demo certs that were shipped with weblogic.
    In this case, the rootca cert can be obtained from DemoTrust.jks
    this is documented at http://e-docs.bea.com/wls/docs90/plugins/isapi.html#114851 (should be same for any plugins)
    Apache plug-in can understand .crt extension.

  • Failing over Oracle connections in a pool

              Hi,
              This message is probably a bit out of context (I've already posted
              it to the JDBC group). I post here as well, since I guess it's
              the place where people have the most experience with clustering
              and HA. Original posting below...
              Could you please tell me whether, yes or no, connections to an
              Oracle database should fail over (when the database fails over
              to another machine)? I use Oracle's Transparent Application Failover
              (configured via Net8) with Weblogic 6 on Linux and Oracle 8.1.7
              on Solaris/SPARC.
              If this doesn't work in my configuration, is there any configuration
              where it should work? (Another version of Oracle, WLS, OS, ...)
              When I try TAF using the PetStore application, I get exceptions
              related to no being connected to the database.
              If TAF doesn't work with WebLogic, is there a way to work around
              the problem? Can I catch these exceptions and renew the connections
              in the pool? Or, what else is possible...?
              I'd appreciate any help. I'd like to demonstrate our HA product
              with WLS. If it doesn't work, I'll turn to iPlanet instead. Pity,
              I really like WLS!
              Thanks in advance for any help or advice!
              Regards, Frank Olsen
              

              Hi (Frank ;-)
              I got carried away a bit too fast...
              Some more testing shows that it doesn't work in all cases:
              - when someone is trying to check out the shopping cart when the
              the database fails (and fails over), I get exceptions once the
              databses has restarted on the backup node
              - the exceptions are related to some transactions being rolled
              back and Oracle stating that it couldn't safely replay the transactions
              - browsing the categories still works fine
              - all access to the shopping cart and sign-in/sign-out causes time-outs
              and exceptions
              Any ideas what may cause this problem, please?
              Regards,
              Frank Olsen

  • How do I fix this-iPad "sync session failed to start"

    I'm trying to sync my iPad.  I have tried via cable and over wifi.  I have done it before.  Now it says "sync session failed to start".
    Can anyone help?
    Also, iBooks on my iPad won't open books anymore.  It says "the requested resource is missing".  What is this?  How do I fix it?
    Thank you!!!!

    Hello Kwastfamily,
    It sounds like you are unable to print from your computer to your printer. I would run through the troubleshooting steps in this article:
    Troubleshooting printer issues in OS X
    http://support.apple.com/kb/ts3147
    Make sure that the printer is powered on, has ink / toner, and that there are no alerts on the printer’s control panel. Note: If you cannot clear an alert on the printer's control panel, stop here and check the printer's documentation or contact the manufacturer for support.
    Ensure the printer is properly connected to a USB port on the Mac or AirPort base station / Time Capsule. If the printer is a network-capable printer, make sure that it is properly connected to your home network.
    Use Software Update to find and install the latest available updates. If an update is installed, see if the issue persists.
    Open the Print & Scan pane or Print & Fax (Snow Leopard) pane in System Preferences.
    Delete the affected printer, then add the printer again.
    If the issue persists, try these additional steps:
    Reset the printing system, then add the printer again.
    If the issue still persists, reset the printing system again.  Download and install your printer's drivers. Then, add the printer again.
    Contact the printer vendor or visit their website for further assistance.
    Thank you for using Apple Support Communities.
    All the very best,
    Sterling

              2. When i don't use "<home-call-router-class-name>common.QARouter</home-call-router-class-name>"
              , there's no exception
              but load balancing does not happen. According to the document , there's must load
              balancing when i call home.create() method.
              my client program goes here
                   DBStateful the_ejb1 = (DBStateful) PortableRemoteObject.narrow(home.create(),

                   or

  • Http cluster servlet not failing over when no answer received from server

              I am using weblogic 510 sp9. I have a weblogic server proxying all requests to
              a weblogic cluster using the httpclusterservlet.
              When I kill the weblogic process servicing my request, I see the next request
              get failed over to the secondary server and all my session information has been
              replicated. In short I see the behavior I expect.
              r.troon
              However, when I either disconnect the primary server from the network or just
              switch this server off, I just get a message back
              to the browser - "unable to connect to servers".
              I don't really understand why the behaviour should be different . I would expect
              both to failover in the same manner. Does the cluster servlet only handle tcp
              reset failures?
              Has anybody else experience this or have any ideas.
              Thanks
              

    I think I might have found the answer......
    The AD objects for the clusters had been moved from the Computers OU into a newly created OU. I'm suspecting that the cluster node computer objects didn't have perms to the cluster object within that OU and that was causing the issue. I know I've seen cluster
    object issues before when moving to a new OU.
    All has started working again for the moment so I now just need to investigate what permissions I need on the new OU so that I can move the cluster object in.

  • Thin Client connection not failing over

    I'm using the following thin client connection and the sessions do not failover. Test with SQLPLUS and the sessions do fail over. One difference I see between the two different connections is the thin connection has NONE for the failover_method and failover_type but the SQLPLUS connection show BASIC for failover_method and SELECT for failover_type.
    Is there any issues with the thin client the version is 10.2.0.3
    jdbc:oracle:thin:@(description=(address_list=(load_balance=YES)(address=(protocol=tcp)(host=crpu306-vip.wm.com)(port=1521))(address=(protocol=tcp)(host=crpu307-vip.wm.com)(port=1521)))(connect_data=(service_name=ocsqat02)(failover_mode=(type=select)(method=basic)(DELAY=5)(RETRIES=180))))

    You have to use (FAILOVER=on) as well on jdbc url.

    Example: TAF with Connect-Time Failover and Client Load Balancing
    Implement TAF with connect-time failover and client load balancing for multiple addresses. In the following example, Oracle Net connects randomly to one of the protocol addresses on sales1-server or sales2-server. If the instance fails after the connection, the TAF application fails over to the other node's listener, reserving any SELECT statements in progress.sales.us.acme.com=
    (DESCRIPTION=
    *(LOAD_BALANCE=on)*
    *(FAILOVER=on)*
    (ADDRESS=
    (PROTOCOL=tcp)
    (HOST=sales1-server)
    (PORT=1521))
    (ADDRESS=
    (PROTOCOL=tcp)
    (HOST=sales2-server)
    (PORT=1521))
    (CONNECT_DATA=
    (SERVICE_NAME=sales.us.acme.com)
    *(FAILOVER_MODE=*
    *(TYPE=select)*
    *(METHOD=basic))))*
    Example: TAF Retrying a Connection
    TAF also provides the ability to automatically retry connecting if the first connection attempt fails with the RETRIES and DELAY parameters. In the following example, Oracle Net tries to reconnect to the listener on sales1-server. If the failover connection fails, Oracle Net waits 15 seconds before trying to reconnect again. Oracle Net attempts to reconnect up to 20 times.sales.us.acme.com=
    (DESCRIPTION=
    (ADDRESS=
    (PROTOCOL=tcp)
    (HOST=sales1-server)
    (PORT=1521))
    (CONNECT_DATA=
    (SERVICE_NAME=sales.us.acme.com)
    *(FAILOVER_MODE=*
    *(TYPE=select)*
    *(METHOD=basic)*
    *(RETRIES=20)*
    *(DELAY=15))))*

  • Stateful bean not failing over

              I have a cluster of two servers and a Admin server. Both servers are running NT
              4 sp6 and WLS6 sp1.
              When I stop one of the servers, the client does n't automatically failover to
              the other server, instead it fails unable to contact server that has failed.
              My bean is configured to have its home clusterable and is a stateful bean. My
              client holds onto the remote interface, and makes calls through this. If Server
              B fails then it should automatically fail over to server A.
              I have tested my multicast address and all seems to be working fine between servers,
              my stateless bean work well, load balancing between servers nicely.
              Does anybody have any ideas, regarding what could be causing the stateful bean
              remote interface not to be providing failover info.
              Also is it true that you can have only one JMS destination queue/topic per cluster..The
              JMS cluster targeting doesn't work at the moment, so you need to deploy to individual
              servers?
              Thanks
              

    Did you enable stateful session bean replication in the
              weblogic-ejb-jar.xml?

  • Why DML not failed over in TAF??

    Hi,
    I have an OLTP application running on 2 node 10gR2 RAC(10.2.0.3) on AIX 5.3L ML 8. I have configured TAF here for SESSION failover.I would like to know two things from you all:
    1) Though each instance is able to read other instnace's undo tablespace data and redolog, then allso why TAF is not able failover the DML transactions?
    2) As of now is there any way to failover the DML other than cathing the error thrown back to application and re-executing the query?Is it possible in the 11gR1?
    I am gratefull to you all if you are sparing your valuable time to answer this.
    Thanks and Regards,
    Vijay Shanker

    Re: Failover DML on RAC
    The reason is transaction processing and its implications.
    Imagine that you updated a row, then waited idly, then some other session wanted that same row and waited for you to either rollback or commit.
    You failed.
    Automatically, Oracle will rollback your transaction and release all your locks.
    What should the other session do: wait to see that maybe you have TAF or FCF and will reconnect and rerun your uncommitted DML, or should it proceed with its own work?
    Failed session rollback currently happens regardless of whether you or anybody else have TAF, FCF, or even whether you have RAC.
    But in order for you to be able to replay your DML safely after reconnect, that transaction rollback had to be prevented, and your new failed over session should magically re-attach to the failed session's transaction.
    Maybe some day Oracle will implement something like that, but it's not easy, and Oracle leaves it up to the application to decide what to do (TAF-specific error codes).
    On the other hand, replaying selects is fairly easy: re-executing the query (with scn as of the originally failed cursor to ensure read-consistency) and re-fetching up to the point of last fetch.
