Ignore my previous Q. Clearer descriprition of JMS FAilover problem

          I'm using weblogic700 .
          I have a cluster( say mycluster) and two weblogic servers ms1 and ms2 in this cluster.
          I have configured a connection factory and its target is assigned to my cluster.
          I have configured a JMS Server and its target is assigned to ms1.
          It has a destination myqueue.
          The listen address for ms1 and ms2 is host1
          The listen port for ms1 and ms2 are 7011 and 7021.
          Now I deploy a message driven bean to mycluster.
          I have a JMS client. Using it if I send a message with a PROVIDER_URL t3://host1:7011
          then the message is consumed.
          (the message is sent to myqueue and the message driven
          bean consumes messages at myqueue).
          Now what should I do If ms1 stops.How can I support failover( even it requires
          some manual steps.)
          So my Question is: How do use the facilty of migration of pinned services in
          this case?
          Also as in the case of servlet and jsp where I can get a common entry point(
          the host and port number of the proxy server which I got by configuring the HTTPClusterServlet)
          how can I get a common address which I will use in my client for sending my
          messages ?
          I feel I am not supposed to use individual server addresses in sending my messages
          to my message driven bean deployed in cluster.

          Be honest, the Weblogic document about multiple instances require you have multiple
          IPs (names) for the same machine and each IP refers to 1 instance,this way, you can
          always use the same port. I am not sure how to implement this concept. Grab your
          system and network administrator to help you.

Reset previous year cleared item

Dear experts,
i am trying to reset previous year vendor cleared document in transaction FBRA.
while doing system is giving message "Archiving has not finished"
message no:F5682.
is there any transaction code is there to reset previous year cleared item?
we are using ECC 5.0 version.
Regards
babu..

Dear Babu,
           The error message F5 682 is raised due to the check described
in note 210134. Due to program design this check is also done for a
'planned' archiving job, not only for actual 'running' archiving job,
as a 'planned' archiving job could be running the next month, and then
cause inconsistencies if for a document that is selected in this archive
run, the clearing is reversed on the same time.
As assuring data consistency in archiving has a very high priority this
check on 'planed' archiving jobs is done and is not planed to be
changed in future.
Solution:
Follow recommendations of note 210134, and check your live Customizing
in table T070 and T071 via Transaction OBR7/OBR8.
Only with regard to the life do potentially archivable documents
cause problems for the resetting of cleared items.
Also, as you may known, please check that there are no invalid /
incomplete archiving sessions within your system via SARA -> Management.
Within transaction SARA (archiving object FI_DOCUMNT) you have to press
the 'Managment' button to see the status of the different archiving runs
. Making a click on the incomplete archiving session you get a popup,
where you can mark the flag 'Invalid session'.
By marking this field you are declaring the contents of this archive
file as invalid. Therefore the archive can no longer be interpreted. The
archiving session can no longer be chosen for subsequent processes such
as Read, Delete etc.
OR
Delete the archive jobs that are scheduled to run.
I hope this helps.

Java 6 you can't as Apple maintains it, and Java 7 you could if you uninstall it and Oracle provides the earlier version which they likely won't his last update fixed 37 remote exploits.
Java broken some software here and there, all you'll have to do is wait for a update from the other parties.

Hi freezebri,
The following steps may resolve your issue:
Apple TV: Basic troubleshooting
http://support.apple.com/kb/ht1551
If your TV screen appears fuzzy or black (you see no video)
Make sure the television you are using supports the Apple TV resolution requirements. Please see the Apple TV technical specifications.
When you connect power, check to make sure the LED turns on. If the LED is not on, then verify with a known good power outlet or connect something else to the outlet you're using for Apple TV and make sure it works (such as a lamp or clock).
Make sure you're using the correct video cables and that they are connected firmly to Apple TV and to your TV.
Connect the HDMI cable directly into the Apple TV and your television, remove any third party devices or adapters.
Make sure the input setting you've selected on your TV matches the input you have your video cables connected to. See the documentation that came with your TV for more information.
Change the Apple TV resolution by pressing and holding the Menu and Up button for six seconds. The Apple TV will automatically cycle to the next resolution at approximately 20 second intervals. Pressing the Selectbutton will immediately cycle to the next resolution.
If you are connected via HDMI, try unplugging and replugging your HDMI cable.
If HDMI isn't working on an Apple TV (1st generation), try component cables instead (and disconnect the HDMI cable temporarily). Read more about HDMI vs component video.
Hope this information helps ...

OSB 10.3 JMS queue problem: JMSCorrelationID is null

Hi everybody,
I am new to OSB/ALSB, and need some help regarding JMS message handling. I am trying to put some input data into a JMS queue( say, reqQueue) and to get the response from another JMS queue(say resQueue). My architecture is:
OSB proxy service->OSB business service->JMS queue(reqQueue)->BPEL process(through JMS adapter) ->JMS queue(resQueue)->OSB business service->OSB proxy service.
I have used JMSCorrelationID for response correlation. but my problem is that when I am trying to test the service from proxy service, I am getting the JMSCorrelationId as null in BPEL process as well as in the weblogic server JMS log, and as I am getting the CorrelationId as null, I am unable to correlate the response, so I am not getting any response.
This is urgent, please help me as soon as possible as possible.
Thanks in advance.

JMS Failover with Distributed Destinations in 7.0

          How does JMS failover with distributed destinations in WL 7.0?
          In an environment using file stores for persistent messages, can a working server
          automatically pick up unprocessed and persisted messages from a failed server?
          If so, what's the best way to set this up?
          Or, is this completely manual? In other words, we have to bring up a new server
          pointing to the location of the file store from the failed server?


          It appears that two JMSServers cannot share the same file store and, I'm assuming,
          two file stores cannot be using the same directory for persistence.
          So the HA you're talking about is something like Veritas automatically restarting
          a server (or starting a new one) to process the messages in the persistent queue
          that were unprocessed at the time of failure with the file store residing on some
          sort of HA disk array.
          The key point is that a message once it arrives at a server must be processed
          by that server or, in the case of failure of that server, must be processed by
          a server similarly configured to the one that failed so that it picks up the unprocessed
          messages. The message can't be processed by another server in the cluster.
          Or, is there some trick that could be employed to copy from the file store of
          the failed server and repost the messages to the still operating servers?

JMS Failover & Load balancing.

Hi,
I have 4 Managed servers A,B,C,D on 4 physical boxes. We have one JMs server on Box D, All other Managed server uses this only JMS which is on D, if this goes down we loose all messages. I want to have JMS failover in my environment. I suggested to have 4 JMS servers and 4 File stores for each Managed server? my question is that Is weblogic that intellegent that if a client connects to box B JMS server and if the servers goes down, the message will be send top another JMS server?

version of WLS you're using, so I've assumed a cluster and WLS 8.1
For resiliency, you should really have 4 JMS servers, one on each
managed server. Then each JMS server has it's own filestore on the
physical managed server machine.
So, you have JMSA, JMSB, JMSC, JMSD with FileStoreA, FileStoreB,
FileStoreC & FileStoreD.
You should also look at using JMS distributed destinations as described
in the documentation.
In your current environment, if server D goes down, you not only lose
your messages, your application would lose access to your JMS queues?
If you use distributed destinations, and have 4 JMS servers, your JMS
queues will still be available if a single server goes down.
If a server does go down however, you have to follow the JMS migration
procedures to migrate the JMS service from the failed server to a
running one.
There are conditions to this process, which are best found out from the
migration documentation to be honest, rather than describe it here.
We use this setup, and it works fine for us. We've never had to use JMS
migration, as so far we haven't had anything serious to cause us to need
to migrate. Our servers also boot from a SAN which makes our resilience
processes simpler.
Hope that helps,

Document for JMS Failover Implementation On WebLogic

Hi,
I am looking some good links and techniques to implement JMS failover using WebLogic 10.3.
FailOver* [As we do with our Databases (Concept of Clustring)]
System will consist of two app servers and each will have its own application deployments but if one failed for some reason the application messages should redirected to the other servere and vice versa.
Above efinition is very brief but if anyone can help provide some good documents and info how to implement it it will be appriciated.
Thanks :-)

Thanks alot guys for your help. We successfully implemented it at our servers here by creating distributed queues targetting all servers in a cluster.
One point which I think is worth mentioning and I want to share with all us here is that; when App Server [where MDB will post the message finally after retrieving from queue] if that goes down what will happen, what MDB will do with that message?.
We impleneted the DLQ (error destination) and deploy one more MDB_DLQ_SERVER2 (Let say App SERVER 1 is down) which gets triggered when any message comes to DLQ and post that message to some other App Server, Let say message has been read by MDB_SERVER1 on SERVER1 but offcourse actaull server is down so message should get Re-directed to its Error Destination after it expiration peiod or whatever the settings are. DLQ (Error Destination) which is also a distributed destinatrion again targetting all servers in cluster same as actaull Request or Reply queues BUT MDB_DLQ_SERVER2 which is deployed on Server2 is NOT able to read this message. It get triggered but can not access the message.
After debugging for almost a day we found out its because message has been transafed to DLQ but actaully its resides in a FILESTORE_SERVER1 and MDB_DLQ_SERVER2 is not able to access it.
To work with that we have to define MDB_DLQ_SERVER1 to cater the SERVER1 failure and MDB_DLQ_SERVER2 to cater SERVER2 failure.
Reason I am mentioning this because as I said DLQ is also a normal Distributed Queue but at the same time its NOT as Distributed as its says.
Hope you all understand what I just wrote above.
Now I need to implement exactly the same scenario using four seperate physicall machine containing my four servers. I tried this scenario by creating four machines where node manager for each server is running and listning but when I am trying to start the server it gives me Certificate Exception with bad user name and password. Anyway I have seen some posts here regarding this; So i think i'll be fine.
Thanks Again,
Sheeraz

Previous button clears my online form...

I'm using MIE 9 and I have created a form of 5 pages.
when I want to see my answers for example on the first page and i hit previous to go back the form clears it self...
Is this still the same problem as here?
http://forums.adobe.com/message/4434484#4434484
Thanx for your answer!

I support TA257, I subscribed to Form Central being a heavy user of FormEntry hoping to switch to Adobe product. Huge oversight from my side as I have the same issue as T, my users cannot fill their form in one attempt, it requires customer interaction and repeated entries. If they close the browser they are done, all work wasted! This makes it unsuable for me. Beautiful product, if a "save and continue later" feature was available it would give you the edge over all the offline products available. Even if the user had to login to be recognized later and even with a time limit before the uncompleted form gets deleted if there are serve space issues...
As a heavy form user (with another provider) and Adobe advocate I urge you guy to consider these requests. Adobe's functioanly, reliability and name alone would give you competitive advantage over the other products. When you have users like me that have spent thousands of dollars on competitor software, a server for data collection and distribution on a solution like FormEntry and ready to dump it all to switch to Adobe for a simple feature, I think you guys should at least consider as I am sure I am not the only one. Your forms can be used for much more than a simple "quick data collection" tool, extensive data colletion, field reports etc... This would unlock the possibilities of a mere data colleciton tool.
I know the offline form can be saved but in this competitive market a form without logic or features does not compete with other competitive products.
Thank you for listening.

Previous Recipients cleared after update?

After I allowed the latest security update to download and install, my previous recipients in my Mail program were cleared!
Can I get it back to pre-update status? I need those emails!
Anyone else had this problem and found a solution?

Hi,
Just had exactly the same problem. But it seemed to have healed during the evening. The problem is that I don't exactly know what I did that changed the behaviour of Mail.
1) I tried to open iCloud in Sys pref. It hangs, still.
2) Same thing with Accounts in Sys pref.
3) Opened Address book for the first time. It seems to have problems to connect to iCloud properly. Get the lost connection sign.
4) I copied the file mentioned above to my desktop. (~/Library/Application Support/AddressBook/MailRecents-v4.abcdmr). I wanted to have a look at it and opened it up with TextWrangler.
After all this messing around, it worked. I'm sorry that I can't give you an exact answer. It seems like iCloud might be an issue. Also opening the file MailRecents might, might have affected something. Now this is wild guessing.
NB. iCloud works now from Sys pref. Hm... Is this necessary to get previous recipients working?... Clueless...

However, when I relaunch Firefox, the 'Restore Previous Session' is highlighted under the History menu and I can restore the previous session.
How is this happening?
Thank you.

It is possible that there is a problem with the files sessionstore.js and sessionstore.bak in the Firefox Profile Folder.
Delete the files sessionstore.js [2] and sessionstore.bak in the Firefox Profile Folder.

If you see files sessionstore-##.js with a number in the left part of the name like sessionstore-1.js then delete those as well.<br />
Deleting sessionstore.js will cause App Tabs and Tab Groups and open and closed (undo) tabs to get lost, so you will have to create them again (make a note or bookmark them).
