ActiveMQ अपवाद है जब

Question

विन्यास रोक: Redhat 5.3 सन जावा 1.6.31, ActiveMQ 5.4.2

मैं हर बार जब मैं ActiveMQ रोक एक अपवाद हो रही है ($> सेवा ActiveMQ रोक)

प्रक्रिया अभी भी मरती है लेकिन कृपा से नहीं। कोई सुझाव?

Answer 1

मुझे एक फिक्स मिला है, लेकिन मुझे यकीन नहीं है कि यह रूट समस्या को संबोधित करता है। एक बार जब ActiveMQ शुरू कर दिया है मैं निम्न आदेश का उपयोग कर यदि पोर्ट 1099 वास्तव में खुला है देखने के लिए जाँच:

$> netstat -lptun | grep 1099 

यह आदेश प्रिंट कुछ भी नहीं दिखा रहा है कि बंदरगाह खुला नहीं है (ActiveMQ शुरू कर दिया साथ)। इसका मतलब यह है कि भले ही ActiveMQ शुरू हो गया है, यह किसी भी जेएमएक्स कनेक्शन को नहीं सुन रहा है (इस प्रकार स्क्रिप्ट इसे रोकने का प्रयास करेगी)। कुछ देखने के बाद मुझे यह link मिला जो मुझे {ACTIVEMQ_HOME} /conf/activemq.xml फ़ाइल पर ले गया।

<!-- 
    The managementContext is used to configure how ActiveMQ is exposed in 
    JMX. By default, ActiveMQ uses the MBean server that is started by 
    the JVM. For more information, see: 

     http://activemq.apache.org/jmx.html 
--> 
<managementContext> 
    <managementContext createConnector="false"/> 
</managementContext> 

स्थापना createConnector = "true" का समाधान मेरी मुद्दों (जब ActiveMQ शुरू होता है इस JVM भीतर MBean सर्वर शुरू कर देंगे): इस फ़ाइल में निम्न अनुभाग है। इसके अतिरिक्त

... 
ACTIVEMQ_HOME: /opt/apache/apache-activemq-5.4.2 
ACTIVEMQ_BASE: /opt/apache/apache-activemq-5.4.2 
Connecting to JMX URL: service:jmx:rmi:///jndi/rmi://localhost:1099/jmxrmi 
Stopping broker: localhost 
.. FINISHED 

, इस ध्वज को बदलने के बाद इस बात की पुष्टि कर सकते हैं कि डिफ़ॉल्ट JMX बंदरगाह (1099) ActiveMQ

$> netstat -lptun | grep 1099 
tcp  0  0 :::1099      :::*      LISTEN  30033/java 

शुरू करने के बाद खुला है: बंद उत्पादन अब इस तरह दिखता है (उम्मीद के रूप में)
