Rabbitmq Resource Locked - Cannot Obtain Exclusive Access To Locked Queue


Even if the other client is able to connect to both brokers it will not be able to create the exclusive queues on both, so will not broadcast.Hope that helps.Mark GeibPrincipal To determine whether a connection uses automatic recovery, use langohr.core/automatic-recovery-enabled?: (require '[langohr.core :as rmq]) (let [c (rmq/connectthis contact form

March Hare Home All guides Community Code on Github Other RabbitMQ Ruby clients Error Handling and Recovery with March Hare About this guide Development of a robust application, be it message This is useful when you need to receive a broadcasted message from a specific routing key. If a particular piece of code relies on the queue name being available immediately a callback should be used. The first argument that both of these methods yield to the handler that your application defines is the connection itself. http://lists.rabbitmq.com/pipermail/rabbitmq-discuss/2009-August/004329.html

Rabbitmq Resource Locked - Cannot Obtain Exclusive Access To Locked Queue

This guide explains how the library helps you in dealing with issues like Client exceptions Initial connection failures Network connection failures AMQP 0.9.1 connection-level exceptions AMQP 0.9.1 channel-level exceptions Broker failure Because initial connection failures are due to misconfiguration or network outage, reconnection to the same endpoint (hostname, port, vhost combination) will result in the same issue over and over. When Bunny detects TCP connection failure, it will try to reconnect every 5 seconds. A message MUST not be acknowledged more than once.

The laws of the country of each sender/recipient may impact the handling of EC, and EC may be archived, supervised and produced in countries other than the country in which you For each channel, re-declare queues. These datagrams are near mission critical and so we are building completely, nearly, redundant paths. Only one connection-level exception handler can be defined per connection instance (the one added last replaces previously added ones).

Rabbitmq Exclusive Queue

With RabbitMQ, when broker is stopped using rabbitmqctl stop reply_text will be set to CONNECTION_FORCED - broker forced connection closure with reason ‘shutdown’ Each application chooses how to handle graceful broker see here Reader feedback is key to making the documentation better. Rabbitmq Resource Locked - Cannot Obtain Exclusive Access To Locked Queue When this occurs, the queue is essentially locked for subsequent connections. If an application needs to execute a piece of code after the broker response arrives, {AMQP::Queue#unsubscribe} takes an optional callback: queue.unsubscribe do |unbind_ok| # server response arrived, handle it if necessary...

Delivery tag is simply a channel-specific increasing number that the server uses to identify deliveries. weblink See rabbit logs below: * connection <0.1224.10>, channel 1 - error: * {amqp_error,resource_locked, * "cannot obtain exclusive access to locked queue 'amq.gen-Q6J...' in vhost '/'", * 'queue.bind'} */ $callbackQueue->bind($exchange->getName(), 'rpc_reply'); // To do so, it uses connection.close AMQP method. Please take a moment to tell us what you think about this guide on Twitter or the Ruby AMQP mailing list.

Services like this benefit from using well-known, not server-generated, queue names and so do any other applications that use them. A common technique is to combine Object#method and Method#to_proc and use object methods as error handlers: class ConnectionManager # # API # def connectnavigate here PHP_EOL; $envelope = $callbackQueue->get(); if ($envelope) { echo 'Got response! '; print_r($envelope->getBody()); echo PHP_EOL; exit; } sleep(1); $attempts++; } So in the end I just see error in RabbitMQ's logs: connection

All communication will occur directly on the QUEUE and theoretically bypasses the exchange. $exchange = new AMQPExchange($channel); $exchange->publish(...); QUEUEs & Reply To: When you use AMQPQueue::setName() along with AMQPQueue::declare(), you are Guides related to this one are: {file:docs/Exchanges.textile Working With Exchanges} {file:docs/Bindings.textile Bindings} {file:docs/ErrorHandling.textile Error handling and recovery} RabbitMQ implements a number of extensions to AMQP v0.9.1 functionality that are covered in Authentication Failures Another reason why a connection may fail is authentication failure.

Note that automatic connection recovery is a new feature and it is not nearly as battle tested as the rest of the library.

In the latter case, you can set off a timer to retry when you're ready:init(Config) ->{Timeout, Queue, Params} = parse_config(Config),{ok, Conn} = amqp_connection:start(Params),{ok, Chan} = amqp_connection:open_channel(Conn),State = #state{ connection = Conn, Unless specifically indicated, this message is not an offer to sell or a solicitation of any investment products or other financial product or service, an official confirmation of any transaction, or Attempts to declare a queue with a name that violates this rule will result in a channel-level exception with reply code 403 (ACCESS_REFUSED) and a reply message similar to this: ACCESS_REFUSED Messages flow from producing applications to {file:docs/Exchanges.textile exchanges} that route them to queues and finally queues deliver the messages to consumer applications (or consumer applications fetch messages as needed).

If a client can create both exclusive queues then it will be the UDP broadcaster. Then there will be two consumer applications each able to consume messages from both of the brokers being published to. Maybe you do not like the guide style or grammar or discover spelling mistakes. When a queue is declared, it is empty, so for server-named queues, there is no need to purge them before they are used.

This can be used as a simple load balancing technique or to improve throughput if messages tend to be published in batches. Typically you decide what channels should be using automatic recovery during the application design stage.
