You need to perform this step only if you are using the Business Event System with Oracle8i
Database and you want to use Oracle Message Broker (OMB) to propagate event messages between systems. The WF_EVENT_OMB_QH queue handler translates between the standard Workflow event message structure, WF_EVENT_T, and the structure required by OMB queues, OMBAQ_TEXT_MSG.
After you set up WF_EVENT_OMB_QH, you can assign this queue handler to Business Event System agents that use propagation protocols you have implemented through OMB. See: Agents, Oracle Workflow Developer's Guide.
Note: You do not need to perform this step if you are using Oracle9i Database and higher. In these versions of the Oracle Database, you can use the Messaging Gateway and Internet access features of Oracle Advanced Queuing to propagate event messages, in place of Oracle Message Broker.
Context: You need to perform this step only once.
