从 TomEE 9 控制台我可以看到 activeMQ KahaDB 使用

由于
C:\Windows\system32INFO: Database activemq-data\localhost\KahaDB\lock is locked by another server. This broker is now in slave mode waiting a lock to be acquired
我发现此链接记录了如何自定义配置KahaDB。配置看起来很简单，但是 我只是不知道将配置放在哪个xml文件中？我尝试了
server.xml以下是server.xml的内容：

请注意，日志目录也会遇到同样的问题。最好将整个 activemq 安装放在
system32我误解了这个 activemq 实例是 TomEE 运行时的一部分。
server.xml首先，对于 ActiveMQ 的任何正式部署，我都会在外部运行代理。这只是一种很好的做法，但如果您只有一台 TomEE 服务器，则使用嵌入式实例就可以了。要配置此功能，请将以下内容放入
tomee.xml <Resource
id="ra/activemq"
type="ActiveMQResourceAdapter">
BrokerXmlConfig=
ServerUrl=ssl://your.activemq.host.com:61616
threadPoolSize=10
maximumRedeliveries=0
</Resource>
<Resource
id="jms/xaConnectionFactory"
type="javax.jms.ConnectionFactory">
ResourceAdapter=ra/activemq
poolMaxSize=10
poolMinSize=1
connectionMaxWaitTime=5s
transactionSupport=xa
</Resource>
如果您确实想运行本地代理并想配置它，则需要使用您想要的任何设置创建一个
activemq.xmlactivemq.xml接下来告诉 TomEE 使用您的配置，您需要从 xml 加载代理配置：
<Resource
id="ra/activemq"
type="ActiveMQResourceAdapter">
BrokerXmlConfig=xbean:activemq.xml
ServerUrl=vm://localhost
threadPoolSize=10
maximumRedeliveries=0
</Resource>
<Resource
id="jms/xaConnectionFactory"
type="javax.jms.ConnectionFactory">
ResourceAdapter=ra/activemq
poolMaxSize=10
poolMinSize=1
connectionMaxWaitTime=5s
transactionSupport=xa
</Resource>
tomee/libvm://localhostlocalhost希望这有帮助！
终于能够配置 TOMEE activemq 以使用不同的 KahaDB 文件夹。我按照 document 中的说明进行操作（请参阅“带有 activemq.xml 的内部 ActiveMQ 代理”部分）。以下是说明的简短摘要和一些附加说明：

是什么阻止您将此 activemq/activmq-data 目录移动到非 system32 位置？
