Drools Workbench-VFS存储库群集-Workbench资产未同步

Question

我正在部署Drools Workbench，并安装了VFS群集。我遵循了Drools-6文档中“ VFS-CLUSTERING”部分中定义的步骤以及以下链接。但是我的存储库没有同步

http://mswiderski.blogspot.com.br/2013/06/clustering-in-jbpm-v6.html

但是要遵循Zookeeper例外。

/ jbpm-集群/ INSTANCES / nodeOne_11 / MESSAGES / df7cda63-979b-47b2-ac9a-f2b218cb188的NoNode

问题在Workbench-A中创建的BPMN流程未与Workbench-B同步。以下是项目资产差异的屏幕截图。附在“ ServerAssets.png”中的图像

Helix命令启动和群集设置

1.       helix-core-0.6.3\bin>helix-admin.bat --zkSvr localhost:2199 --addCluster jbpm-cluster
2.       helix-core-0.6.3\bin>helix-admin.bat --zkSvr localhost:2199 --addNode jbpm-cluster nodeOne:11
3.       helix-core-0.6.3\bin>helix-admin.bat --zkSvr localhost:2199 --addNode jbpm-cluster nodeTwo:22
4.       helix-core-0.6.3\bin>helix-admin.bat --zkSvr localhost:2199 --addResource jbpm-cluster vfs-repo 1 LeaderStandby AUTO_REBALANCE
5.       helix-core-0.6.3\bin>helix-admin.bat --zkSvr localhost:2199 --rebalance jbpm-cluster vfs-repo 2
6.       helix-core-0.6.3\bin>run-helix-controller.bat --zkSvr localhost:2199 --cluster jbpm-cluster 2>&1 > /tmp/controller.log &

ZooKeeper设置

    Changes done only in zoo.conf
1.       dataDir = /zooDir/zookeeper  (Not sure where this directory gets created as I could not find it in $zookeeper_home/)
2.       clientPort = 2199

Work-Bench A配置：Standalone.xml

 <property name="org.guvnor.m2repo.dir" value="D:\\Servers\\M2_REPO"/>
    <property name="org.uberfire.nio.git.dir" value="D:\Servers\Drools-6-Deployment\repo"/>

    <property name="org.uberfire.cluster.vfs.lock" value="vfs-repo"/>
    <property name="org.uberfire.cluster.autostart" value="false"/>

Answer 1

我找到了解决方案。

Jboss群集应仅在JBoss-Domain模式下配置。

Answer 2

我现在面临着同样的问题。我在7.26版中使用域模式。工作台数据未同步。我不确定动物园管理员如何知道要同步的仓库。我这样配置服务器：

<system-properties>
                <property name="org.uberfire.nio.git.dir" value="/jbpm/bpm/.niogit" boot-time="false"/>
                <property name="jboss.node.name" value="nododos" boot-time="false"/>
                <property name="org.uberfire.cluster.id" value="jbpm" boot-time="false"/>
                <property name="org.uberfire.cluster.zk" value="10.38.32.36:2181,10.38.32.37:2181" boot-time="false"/>
                <property name="org.uberfire.cluster.local.id" value="nododos_12346" boot-time="false"/>
                <property name="org.uberfire.cluster.vfs.lock" value="vfs-repo" boot-time="false"/>
                <property name="org.uberfire.nio.git.daemon.port" value="9419" boot-time="false"/>
                <!--<property name="org.uberfire.metadata.index.dir" value="/jbpm/jbpm" boot-time="false"/>-->
                <property name="org.uberfire.cluster.autostart" value="false" boot-time="false"/>
            </system-properties>

这是Zookeeper日志的一部分：

zookeeper从jboss / jbpm读取和同步数据的正确配置是什么？我只读的每个文档都说：配置Zookeeper，启动Zookeeper ...
