Considerations For Task Data In webMethods Cluster Environment | Post Details - SKML Home Tuitions
A Business process consists of one or many automated or manual activities. An automated activity is a step that is performed directly by the execution engine while a manual activity involves human interaction. Manual tasks also known as human tasks in BPM (Business Process Management) nomenclature. As much as processes are geared towards automated tasks, involvement of a human in a process is inevitable. Examples include approving a large loan, overriding a system generated decision etc.
Task
In webMethods (7.1.2), Tasks are run on the Task Engine (TE) in My webMethods Server (MWS). When the Process Engine encounters a task in a process, the control is passed to Task Engine in MWS. The status of the process will change to started queued and the task is eligible for a user from the task queue.
A task consists of 2 parts: Task Info and Task Data. Task Info contains task meta data such as created, updated dates etc and Task Data contains the business data available for display. In J2EE world, task Data closely resembles Data Transfer Object (DTO) in the presentation layer. Within webMethods, task Data is a document in Integration Server and persisted in T_TASK_DATA table as a blob object. Task Data also provides the facility to save data and retrieve them later.
Task Updates
Tasks are updated via WmTaskClient package, web service API or MWS API. The Task Client package is simply a convenient wrapper for the web services running in TE. Task API provides a number of methods but in this blog the focus is on two methods: updateTask and getTask .
An update to a task consists of 2 steps: Persists task to task data tables and updates the cache maintained by TE. The impact of cache update in TE is not significant in a non clustered environment to warrant a further discussion. However, in a clustered environment, this can present a problem for remote TE web service APIs, including APIs from the WmTaskClient package. Since the application is running on a clustered environment, the getTask API call can be routed by a load-balancer to any node in a MWS cluster. In this case, it is possible that the call may return incorrect (out of date) data, because the cluster node has not been updated yet. The worst is yet to follow. A user without knowledge of this stale data will happy to carry on till they invoke an action to save task data again. At this point, TE will detect that update request contains older data and hence will return an exception (âTask has not completed update cycle, please refreshâ ) to the user. In this instance, the most likely outcome for the user is to re-enter data. In the meanwhile, it wouldnât matter if there is no immediate call to fetch data after an update call. This is because after some delay, depending on network and number of nodes in a cluster etc, all the nodes in a cluster will be updated and hence subsequent calls to get task data will return the âupdatedâ data.
To ensure that up-to-date data is always returned, webMethods suggests the following option (applicable only to cluster environments):
The default value is false. If set to true, any task update operation will attempt to synchronously refresh caches on all other cluster nodes and wait until other cluster nodes report back that their caches have been updated. A disadvantage to setting this option to true is that any task update operation will have to wait until all cluster nodes are refreshed. This does not introduce any additional load on the server, but it does increase task update operation response time
Another suggestion (in addition to the above) is setting the lightweight option to true as shown below:
When using the Task Engine to complete a large volume of tasks, the JMS queue (backed up by database table T_TASK_JMS) may become plugged. Part of the solution is to use lightweight queueing (JVM backed queuing) of task events. To turn this setting on, add the following JVM System property to the server.properties.bat or .sh file. The effect of using lightweight queuing is a much lighter load to the database (avoid database table) and faster task-rules processing at the cost of a slightly increased chance of data loss in the case of a software or hardware crash.
None of the above options seem to offer a complete solution to the problem. Therefore, it is necessary to take this limitation in designing an application with Task Data in a clustered environment.
Considerations:
Size of task data :Avoid updateTask and getTask calls :Save data in a session : Store Task Data elsewhere :Avoid mutable data in queue columns :
