Browse BDB JE Store

Hi, Does anyone know of any utility that can be used to browse the BDB datastore? I'm specifically looking for a tool that will let me inspect a .je file and display all the databases, key - value pairs present in the file. I looked at the JMX plugin and the Jconsole plugin that BDB ships wit

Re: problem with qpid heartbeats when sending msgs with size over 1KB

Hello, we are having a problem with our MRG (qpid) system: * when sending messages with size of 1600bytes, a connection (used for sending from client) does not detect the host connection is lost via heartbeat timeout. + we are using C++ qpid client 0.7 and qpidd 0.7 (linux 2.6 x86_64 on both cli

Re: how to delete queue from jms client

Gaston, I forgot to ask, but you are using the C++ broker aren't you? I'm pretty sure that the Java broker doesn't support timed auto delete, and as I mentioned before the C++ broker supports this from version 0.10 Frase Fraser Adams wrote: Hi Gaston, Try the following syntax (BTW IIRC you ne

Re: Jave Client with C++ Broker - Messages in Queue-size?

I'm afraid that I can't think on any really elegant solutions. Re "I need some kind of notifications from JMS Client API that I am able to send". I don't think that the JMS API has a mechanism for doing this, though I may be wrong. The best approach that I can think of at the moment is to i

Hi Gaston, Try the following syntax (BTW IIRC you need at least Qpid 0.10 for timed auto deletes to work): Also I can't claim credit for the following, this was a response from uber-guru Gordon Sim when I asked a similar question back in July To create a 'shared' queue on-demand: my-queue; {

Re: Jave Client with C++ Broker - Messages in Queue-size?

Thanks -- I need the queue size because I am not sure how to find out when i can send messages to a durable queue after i get JMS Exception that the queue is max-ed out. I was testing and I send 1 message and I changed the jfile to 4 so I get Queue Filled Exception. Then I started a receiver t

no, just drop the tcp option from your connection address if in use. If not, then I'll let Kim pick up and comment on the thread. Carl. On 12/06/2011 02:25 PM, dmounessa wrote: > I am using geronimo-jms_1.1_spec-1.0.jar > > Do I need a new version? was this released? > > > > -- > View this m

Hi, Long post follows, hope it's useful Cheers, Frase IIRC C++ brokers from 0.10 onwards have both QMF1 and QMF2 enabled by default, the 0.8 broker needs to have it explicitly enabled with "--mgmt-qmf2 yes" if you do qpidd -h you'll see all the options. Re "where can I get the list of

Dear Fraser, I need to configure the auto-delete arguments, with this parameter: arguments:{'qpid.auto_delete_timeout':120} When I create the queue, the logs show a empty field argument. Log: main 2011-12-06 15:45:54,562 DEBUG [apache.qpid.transport.Connection] SEND: [conn:db23f1] ch=0 id=2 Queue

Re: Jave Client with C++ Broker - Messages in Queue-size?

Hi all, Although Pavel mentioned https://issues.apache.org/jira/browse/QPID-3302 And the need for a patch for Qpid < 0.12 to use QMF2 with Java there's also an issue with respect to returning Lists. Basically JMS doesn't support amqp/list Here's some code to help. HTH Frase /**

Re: how to delete queue from jms client

Here's some Java code for method invocation. This largely follows a similar pattern to Pavel's C++ example. Note that this method is taken from a much larger QMF2 API that I've written ,so there's some dependencies on other classes (you won't be able to use it directly, but hopefully you'll get

Re: how to delete queue from jms client

Hi Gastón, you can use QMF method "delete" with parameters "type" ("queue" in our case) and "name" (name of the queue). Here is the code snippet from C++ program I use: Connection connection(url/*, connectionOptions*/); try { connection.open(); Session session = connectio
