Designing the Process Performance and stability of executing automated workflow activities The Process Engine’s multi-threaded workflow allows concurrent execution of automated workflow activities. The workflow agent responds to Content Server notifications and can execute queries based on a polling interval to claim work for its worker threads to execute. There are only two ways the workflow worker threads can execute the work: • Notification: They get notified through shared memory inter-process communication (IPC). • Claim query: The workflow master runs the UPDATE query that claims available items for working and then distributes the work to workers. If the automated workflow activities are not executing on time or never at all, check for the following: • The claim query can take too long to execute. This can occur when the number of worker threads is increased to a high number (for example, 100) with the intent that more workers results in better performance. However, with this increase, the UPDATE query executes as a nested loop in the underlying RDBMS, pinning the RDBMS CPU. This dramatically increases the time that it takes to execute the claim query. Check the statspack for top queries and if the UPDATE on dmi_workitem_s is taking a long time, then it is a confirmation of the problem. • Content Server is configured for high availability. With a Content Server high availability configuration, confirm that a unique dm_server_config object is specified for each content server. If you have two workflow masters operating using the same serverconfig object, then workflow automated activities execution can fail. To fix this problem, ensure that each content server has a unique serverconfig object. • You are not using the no_op method from Process Builder 6.5 or later. In Process Builder 6.5, the default DocBasic no_op method to run the automated activities such as splits, joins, and data mappers was changed. If you are using an older version of dm_noop_auto_method, switch to the newer version of dm_noop_auto_method_java. Large SDTs and performance Creating large SDTs or adding many SDTs to a process degrades performance in TaskSpace task lists. Try to create SDTs based on logically related objects and consolidate attributes if it makes sense within the process. Deployment considerations • Migrating or upgrading Process Builder, page 61 • Process versioning, page 61 60 EMC Documentum xCelerated Composition Platform Version 1.6 Best Practices Guide
Designing the Process Migrating or upgrading Process Builder After upgrading to a newer version of Documentum Process Builder, delete the BOF cache as well as the temp/work directory of the application server, and restart the application server. The cache folder location is specified by the dfc.cache.dir key in the dfc.properties file. It is located in $DOCUMENTUM/cache/bof on the client machine by default. Clearing the bof folder contents clears the BOF cache. Note: The DFC cache folder also contains caches other than BOF. Do not delete these additional cache folders. Process versioning Use versioning carefully and sparingly to avoid creating inconsistencies in the process data. It is best to create versions when deploying a process to the production environment. This is because creating different versions of a process can result in process data getting out of sync. Use versioning carefully and only when the process is moved to a production environment. During design, it is a best practice to use the process debugger frequently to troubleshoot and validate the process without installing it. When the activities and the data model are defined and the debugger is run without errors, then check the process into the repository. Install the process only when you want to run it. Note: It is not recommended to use Save As on a process multiple times and then install each of the cloned processes. This practice can lead to instabilities at runtime. Accessing structured data types from a custom application To gain access to the attributes of structured data types, you can use IDfWorkitemEx and IDfWorkflowEx APIs. Details can be found in the Javadoc files located in Program Files\Documentum\help\bpm\api. Note: During the installation process, ensure you have selected the option to install the developer documentation. This option installs the Javadocs on your local system.
