Node failure scenario: Messages in NO PERSISTANTS distributed topics

• Proxy node failure detection

  Question about the proxy node failure detection to extend clients.
  
  My impression is that, once the connection is established, you won't notice that this proxy node was missing until the next time that you try to access cluster (get, put, etc etc).
  Or there is nothing like something MemberListener that the customer will be notified when proxynode disappeared?
  
  This causes us some problem since we will be adding a map listener breast to expand customer, but we don't receive any notification if the proxy node has disappeared.
  To resolve this problem, we are to implement an approach to heart beat customers who will have a background thread periodically perform cache get to make sure that the connection remains valid.
  
  Above the approach has worked very well for the method of one-time replacement of node, since if the pulse failed, we know something wrong.
  
  However, the approach of heartbeat create new issue when there is more than one proxy node configured in the remote cache of the client system.
  
  That's what we observed.
  
  A client extension configured with a remote cache system has proxyA and proxyB as a proxy list.
  
  1 extend the client starts by connecting to proxyA.
  2. extend the clients subscribe to ABC key for jesuca
  3 kill the proxyA process.
  4. the wire heart rate control background make a heartbeat can jesuca. It seems that during this operation of cacheX.get (), coherence will automatically create a new connection to proxyB. Our application doesn't even notice that there is a switch of proxy node.
  
  Now the question is whether an ABC key update occurred between steps 3 and 4. Our application does receive any notification at all. And we don't even notice there's a new connection created for a different proxynode at all.
  
  Our business requirements demand that we miss no update notification entry to extend clients (unless all the proxy nodes are down) as long as there is at least one available proxy node.
  
  Is there a better approach for this requirement?

  To get events when your connection is lost you need to use a MemberListener

  for example, you can use the cache that you have added the listener too...

  cache.getCacheService().addMemberListener(memberListener);
  

  When you lose the connection range then the memberLeft method will be called on your memberListener and you can then add your listeners to cache.

• Difference between persistent messaging and messaging is not persistent

  Hello
  
  I have a confusion related to persistent Messaging.
  
  According to my knowledge, the message becomes persistent if the JMSDeliveryMode flag is set
  
  SO what - this by defalut?
  
  Where stored for instant messages for non - persistent messages.
  
  Thanks in advance :)

  Persistence of the message is defined by the attribute of mode of delivery for the producer in the JMS message client or it can talk together on a basis of messages in the send operation. The default value for the mode of delivery to the producer of the message is PERMANENT.

  WebLogic JMS has a function to override the shipping method defined by the producer of message. This is the configuration of the Destination where there is an attribute called the Mode of delivery replace which can take the values:

  Not provided: Mode of delivery of the message producer is not overridden
  Persistent: All messages are marked as persistent regardless of the message setting producer
  Non-permanent: all Messages are marked as non-persistent regardless of the message setting producer.

  All non-persistent messages are stored in the memory in case of normal use. If there is a stack to the top of messages, weblogic moves the body of the message the disk in what called a store of pagination for the JMS server, keeping only the headers of the message in memory. The characteristic of non-persistent messages, is that he cannot survive server restart. If these messages even when they are on the disk in the paging store custom survive restart of the server.

• Messages to the JMS OSB topic disappear even when not subscribed

  Hello
  
  We use a service OSB publish xml messages to a weblogic JMS topic. Message is persistent. There is no consumer for the subject. There is no limit set expiration.
  
  We are able to see the message of the OSB reach the subject. He remains in the topic for a few seconds, then disappears.
  
  The status of the message is 'send transaction' on the subject in the weblogic console. And she appears as Message waiting instead of current Message.
  
  Is there a way to make sure that the message remains in the subject, until it is consumed by a Subscriber?
  
  
  Thank you
  Spengler

  Hi Spengler,

  The topic still messages only for subscribers, if there are no subscribers, then it is not necessary keep the message.

  This is the case even for you as well, that there are no subscribers the message is deleted.

  So first of all you must have at least a first Subscriber (a dummy proxy that reads from the topic) and then post on the subject (via your service OSB or hermes jms tool, etc...). If you try to go check out the topic, you will be able to see the message.

  Hope this information helps.

  Thank you
  Patrick

• Reading Messages from a uniform distributed queue without an MDB

  WebLogic Server Version: 10.3.4.0
  
  I am currently facing a problem trying to read messages from a queue of distributed uniform with a spring JMSTemplate Weblogic.
  We have a cluster created with 2 servers.
  Each server in the cluster has it's own server JMS (JMSServer-1, JMSServer-2), each has its own persistent store
  We have a JMSModule. This JMSModule contains a factory connections (Subdeployment = sub1 Target = mycluster) and also contains a uniform tail (Subdeployment = sub1 Target = MyCluster) distributed
  
  A peak at our Spring JNDITemplate configuration looks like:
  < bean id = "messagingJndiTemplate" class = "org.springframework.jndi.JndiTemplate" >
  < property name = "environment" >
  < Accessories >
  < prop key = "java.naming.factory.initial" > weblogic.jndi.WLInitialContextFactory < / prop >
  < prop key = "java.naming.provider.url" > t3://some.server.name1,some.server.name2:8001 < / prop >
  < / Accessories >
  < / property >
  < / bean >
  
  It seems that every time that I call the JMSTemplate.browse function in my client, I'll read the messages in the server 1. Then the next bed request messages that are found on server 2. Each request is sent around in circles.
  
  I then tried to change the JMSModule. The new JMSModule contains a factory connections (Subdeployment = sub1 Target = mycluster) and also contains a uniform distributed Queue (Subdeployment = sub2 Target = JMSServer-1, JMSServer-2)
  
  After this change, it seems that every time that I call the JMSTemplate.browse function, I'll read the messages in any server, I have a session with my client. If I'm logged on server 1, I can only see messages in Server 1 and vice versa.
  
  
  My question is, how to configure Weblogic to pass messages from TWO servers in my cluster? I guess since it was a cluster installation, I would get some sort of uniform distributed queue unique view to access via JNDI, but appears not to be the case.
  Thanks in advance.

  Browsers and receivers always attach to a single member of a destination distributed.

  WebLogic BMD, on the other hand, automatically handle the task of fixing the receivers to each Member and are fairly simple to code and use these days. If you have the possibility to use WL BMD, I recommend their use. (There is no equivalent for the browsers).

  Spring does not have the same STANDARD, but it seems not be a workaround for the spring receiver number (but not for browsers - receivers only). Here is a sample spring impl that attaches a subscription for each Member of a subject is distributed:
  http://sleeplessinslc.blogspot.com/2011/12/WebLogic-JMS-partitioned-distributed.html.

  If the foregoing is not useful and that you must scroll through each message on each server in the cluster, then you must write special code case to check each separately. There are two options to list the destinations and work with each of them - 'messages management' JMX mbean API (WLST Jython scripting or Java-based) and the availability of destination weblogic.jms.extensions API.

• How much time does it take for consistency detect node failure?

  Hello everyone
  
  We have an application that, among other things, using a call to NamedCache.invoke (object, InvocableMap.EntryProcessor)
  distribute work to agents hosted in about 80 JVMs, different with each probably manages a portion of the cache
  key range. In the present case, the cache is managed by a service with a backup-counter 0. EntryProcessor agents
  "on the other side" get an entry based on the key value and put it in the cache. Our questions:
  -If a JVM that hosts the service fails all of a sudden, how much time it take the coherence length to detect failure?
  -How long it take consistency to move the key range that manages a server failing to another JVM?
  -Are the requests sent through InvocableMap.invoke () be queued or retried when the key refers to a series of treaties
  by a failed server?
  
  It is feared that we can face visible to the user failures using a cache in a service with a backup-counter 0.
  
  Thanks for any help

  Depends on coherence version 3.6 running dead ping detection database too is really very fast (about 1 seconds, I think).
  detection of death based on ping earlier or not running is a bit slower, but still fast enough.

  -How long it take consistency to move the key range that manages a server failing to another JVM?

  If you have a backup-counter 0, you will lose all data in partitions in the abnormally missing node. That's why these partitions will bleed on their new owner, and this mission is quite fast. On the other hand, some other partitions must be rebalanced, which can take some time depending on the size of data.

  -Are the requests sent through InvocableMap.invoke () be queued or retried when the key refers to a series of treaties
  by a failed server?

  They can be retried, but since you have lost the partition, you can end up with incorrect data. I don't know what is really happening in this case.

  It depends on what your application, if the content of the cache is missing.

• Message from Weblogic persistent queue must bridge?

  Hi guys,.
  
  I am looking at the document of Weblogic server 10.3, the document it says Weblogic using bridge message message store and shipping of JMS 3 rd-party vender. I had two issues here that I couldn't find answer on the doc...
  
  1. don't we have to configure a persistence queue (A queue which using the persistence store) as source queue for Message Bridge, or bridge of Message has its own way to persist the messages?
  
  2. the document said that it is best to configure instances of the message multi bridge to improve performance, it means that there is no connection with a single message bridge pool? So how much is sufficient.
  
  3. in regard to distribute the queue in the source queue Act, if I have a target distribute the queue and the bridge of a single message to the same cluster, Weblogic automatically assigns messages local instance bridge to connect local member of the queue to distribute?
  
  
  Much appreciate if you can share ideas?
  
  Concerning
  K

  OK, so your case is to forward the message to your environment weblogic to a provider of remote mail (tibco or mq)

  You must follow the following steps.
  1 create a jms destination in your environment local weblogic. If you have persistent messages in this destination, you need to associate a store persistent Server jms hosting this destination. ==> (1)

  2 create a jms provider target jms destination. ===> (2)

  The above 2 steps are jms provider configurations and the ones here are the bridge configuration.

  3. create a destination Source for the local WLS jms destination created in step-1
  4. create a target Destination for the destination of remote jms provider created in step-2
  5. configure the bridge of message instance and associate source and target, created in steps (3) and (4) destinations.

  The instance of bridge transfers messages between (1) and (2).

  If you do not want to be lost during the transfer of messages you must set qualtiy of Service attribute for the message accordingly to step (5) bridge.

  If you want that your messages in the source queue (1) not to be lost in a crash of the WL server, you will need to to be persistent messages as follows:
  1 messages to the queue (1) request must mark as persistent.
  2. the hosting server JMS destination (1) must have a persistent store associate to store persistent messages.

  Note that these two are JMS provider configurations and not the message bridge.

• 0xc19a0020 ink system failure error message

  Hello

  I have a HP Photosmart Plus, product # CN216, model # B210a. I'm running Mac OS X 10.7.5

  Today, I turned on my printer and got the error message "ink system failure 0xc19a0020 please turn printer Off and then on.

  So I did, but still got the error. So, I did the troubleshooting, which told me how to clean the print head. I've done 3 times, but I still get the error. I unplugged the power cord from the printer, then the wall, waited, then reconnected. I still get the error.

  I use the printer at least once a week, so he hasn't been sitting unused for too long.  I have not changed anything or whatever installed lately. The ink cartridges have ink.

  Anything else I can try? The replacement print head is $72!

  Thank you!

  Sorry, but generally, this can be a bad head of printing or bad cartridges. Here is a link that will help you with this problem, even if you did most of these steps.

  http://support.HP.com/us-en/document/c03081973

  If you have already replaced the front print heads and you return to this same stage, it would be a bad printer and maintenance needs.

• HP Officejet 6500 E709n: HP Officejet 6500 E709n - ink system failure error message.

  I have a printer HP Officejet 6500 E709n.  I get the following error message when I turn on the printer:

  'Ink system failure.  "Please turn printer off, then on.

  I then do as instructed and turn the printer off, but then the whenever I re - turn on the printer, I get the same error again.  The printer is now fixed to the top and none of the buttons on the printer works except the Power button on / off.

  Any suggestions on how to proceed?

  Hi @recooke,

  Welcome to the Forums of HP Support! I see that you can not use your HP Officejet 6500 Wireless. You get a printer fault to "turn printer off and then on again" you did without success.

  Please perform a hard reset:

  1. disconnect all cables and cards of memory in the printer.  Unplug the power cord, directly from the back of the printer when the printer is still on.

  2. unplug the other end of the power cord.

  3. If there is a power supply on the power cord, disconnect one end and reconnect it.
      
  4. at the end of 60 seconds, plug it directly into a wall outlet (not a surge protector or battery backup).
      
  5. connect the power cord to the back of the printer.
      
  6. the printer should automatically power back upward.  If not, turn it on with the power button.

  7. try to make a photocopy (if your printer is an all-in one) before you connect the cables from the printer.

  8. connect the other cables needed to the printer.

  It is recommended that the printer is plugged directly into a wall socket to ensure a uniform level of power.  Sometimes, when plugged into a surge protector or battery backup, the quantity of electricity is not received by the printer.  Power problems can cause printing problems.  It is particularly important to be plugged directly into a wall outlet with wireless connectivity problems, "sleep mode" and other power problems.

  Any change?

  If you still see the error, please check your Inbox. I sent you a private message on the Forums.

  Response with the result. I hope this helps.

  Hello

  On question 1, since you use 'authentication mode host multi-domain' then "action dead event server authentication allows vlan X" is the way to go.

  But if you use "authentication host-mode multi-auth" then you should use "action death event authentication server reset vlan X"

  On question 2, it is not mandatory to use pre permission ACL. My current deployment have IP phones, since I use the profiling and CDP RADIUS then ISE can detect and allow the IP phones, even if the switch blocks all packets. "Why I didn't need pre-authorization ACL.

  Please rate if this can help.

• C6180 ink SYSTEM FAILURE error message

  IF ANYONE CAN HELP WITH THIS ERROR MESSAGE?  FAILURE of the SYSTEM of INK 0xc19a0035

  I HAVE A C6180 ALL IN ONE.               IT DOES NOT RECOGNIZE THE FACT

  THAT I HAD REPLACED A CARTRIDGE A MONTH AGO... HP brand AND NOW GET this MESSAGE.

  I RE-SET, CLEANED ALL THE CARTRIDGES AND TALKED WITH HP ON THE PHONE 2 X.   IT WORKS AGAIN FOR A SHORT PERIOD, THEN THE INK SYSTEM FAILURE ERROR APPEARS AGAIN.

  HP said I need a new?   It worked very well until this and always does this for awhile after you reset it, so can't understand

  Why should I go out and get a new one for this problem.  I hope someone can help!    Thank you!

  IS NOT THAT DEMAND THE DAY 'EXPERT' OF AID?  HAVEN'T HEARD ANYTHING YET!

  This same error started on my printer and eventually it would power on and off constantly. Apparently some defective components were used in the construction of the logic board (see photo). My C6180 there were 3 defective capacitors (the Green cylinders - breathtaking top indicates failure) and a 4th from the same manufacturer (TEAPO - many web references unfavourable to this manufacturer). I bought 3 x 330uF 16V and 1 x 680uF 10v rated at 105 degrees Celsius (total about 60cents). On the logic board, the capacitors I replaced are labeled C613, C614, C660 and C662. If you are not comfortable replacing components yourself (or is not a soldering tool), you will need to find someone who will. The repair time should be less than 30 min - I did it in 25 minutes with only a solder pen. This also fixed the ink the printer was to have system failures. A similar fix may apply to other printers.
