Newbie's Question
Hi all, using ActiveMQ-4.2-Snapshot. After starting the broker and posting a message to a queue I get INFO KahaStore - Kaha Store successfully deleted data directory activemq-data/hatest1/tmp_storage and my former filled queues are empty. I set deleteAllMessagesOnStartup="false" because I want ActiveMQ to hold all messages even after restarting it. When the system is up and I push messages into my queues I can see in jconsole that the messages come into my queues. But deleted data directory activemq-data/hatest1/tmp_storage makes me feel like the messages ar only stored somewhere temporarily. Where is my mistake?

Re: [Spam: 5.0] Newbie's Question
Hi Rob, sorry, maybe a silly question, but I think my messages not to be "non-persistent". So what makes a messsage "persistent"? I am using a simple script that produces a number of text-messages. While testing an other JMS-System my messages stayed in that store until they were consumed.

Persistence
I am using in activemq.xml: Nevertheless, when I ant producer it says: producer: [echo] Running producer against server at $url = tcp://localhost:41414 for subject $subject = TEST.FOO [java] Connecting to URL: tcp://localhost:41414 [java] Publishing a Message with size 1000 to queue: TEST.FOO [java] Using non-persistent messages I am testing on 4.2-SNAPSHOT. Why am I unable to produce persistent messages? They are all gone when I restart the broker! HELP please.

Re: Problems with Persistent Messages
Maybe you should check if the messages are really lost by using the program "browse". You find it in the bin-directory. Since 4.2-Snapshot browse is implemented in activemq-admin. I suggest that your messages are still there but Hermes gives you some strange information.

Re: Unable to recognize DB2Driver
You simply need the JDBC Type 4 driver for connecting to DB2 databases. This file is called db2jcc.jar. Get it and put it in ActiveMQ's lib-Dir. garima015 wrote: > > Hi, > > I am using incubator-activemq-4.0.2.jar and is configuring DB2 in > activemq.xml using > > > > > > > > > On start of broker i am getting this error > ClassNotFoundException: com.ibm.db2.jcc.DB2Driver > I searched in forums but seems nobody has got this error before. > Am i missing something in configuration. > Any help will be really appreciated. > -- View this message in context: http://www.nabble.com/Unable-to-recognize-DB2Driver-tf3454188s2354.html#a9638719 Sent from the ActiveMQ - User mailing list archive at Nabble.com.
