lock is locked... waiting 10 seconds for the database to be unlocked

 

今天配置Pure master slave with activeMQ, 碰到如下错误:

C:\apache-activemq-5.4.3\bin>activemq xbean:file:../conf/pure_master.xml

Java Runtime: Sun Microsystems Inc. 1.6.0_24 C:\Program Files\Java\jre6

原因竟是kahadb_pure_master 与 双引号" 之间多了一个空格.

 

错误:
        <persistenceAdapter>
            <kahaDB directory="${activemq.base}/data/kahadb_pure_master "/>
        </persistenceAdapter>

 

 

 

正确
        <persistenceAdapter>
            <kahaDB directory="${activemq.base}/data/kahadb_pure_master"/>
        </persistenceAdapter>
