SOASuite_014：Oracle ESB 10g 问与答

问题1：OSB与OESB的区别？
Oracle Service Bus (OSB)前身是BEA的AquaLogic Service Bus，是一个独立的ESB产品。OSB在业界有很高的知名度，目前OSB只能运行在 WebLogic Server上。
Oracle Enterprise Service Bus (OESB) 是SOA Suite 10.1.3.1的一个重要组件。OESB的知名度不如OSB，但是OESB可以运行在OC4J 和WebSphere上。
问题2：OESB会继续开发并支持旧的客户吗？
是的。OESB将会一直作为是SOA Suite 10g的一个重要组件。
并且，使用ESB10.1.3开发的ESB，可以升级到SOA Suite 11g中的mediator部件中。





问题3：运行时遇到一个错误：

The exception reported is: "oracle.tip.esb.monitor.MonitorException: 无法构建实例关系, 因为没有必需的元数据 at oracle.tip.esb.monitor.manager.database.MetadataProvider.getRelationshipXML(Unknown Source) at oracle.tip.esb.monitor.manager.database.DBActivityMessageStore.getInstanceRelationship(Unknown Source) at oracle.tip.esb.console.XMLInstanceManagerImpl.getRelationship(Unknown Source) at oracle.tip.esb.configuration.servlet.command.GetTrackingDetailsCommand.execute(Unknown Source) at oracle.tip.esb.configuration.servlet.CommandServlet.doJob(Unknown Source) at oracle.tip.esb.configuration.servlet.CommandServlet.doPost(Unknown Source) at javax.servlet.http.HttpServlet.service(HttpServlet.java:763) at javax.servlet.http.HttpServlet.service(HttpServlet.java:856) at com.evermind.server.http.ResourceFilterChain.doFilter(ResourceFilterChain.java:64) at oracle.security.jazn.oc4j.JAZNFilter$1.run(JAZNFilter.java:396) at java.security.AccessController.doPrivileged(Native Method) at javax.security.auth.Subject.doAsPrivileged(Subject.java:517) at oracle.security.jazn.oc4j.JAZNFilter.doFilter(JAZNFilter.java:410) at com.evermind.server.http.ServletRequestDispatcher.invoke(ServletRequestDispatcher.java:621) at com.evermind.server.http.ServletRequestDispatcher.forwardInternal(ServletRequestDispatcher.java:368) at com.evermind.server.http.HttpRequestHandler.doProcessRequest(HttpRequestHandler.java:866) at com.evermind.server.http.HttpRequestHandler.processRequest(HttpRequestHandler.java:448) at com.evermind.server.http.AJPRequestHandler.run(AJPRequestHandler.java:302) at com.evermind.server.http.AJPRequestHandler.run(AJPRequestHandler.java:190) at oracle.oc4j.network.ServerSocketReadHandler$SafeRunnable.run(ServerSocketReadHandler.java:260) at com.evermind.util.ReleasableResourcePooledExecutor$MyWorker.run(ReleasableResourcePooledExecutor.java:303) at java.lang.Thread.run(Thread.java:595) ".
