Error description
There exist two kinds of coaches as a user interface for human services. Only the new coaches will support the collaboration feature. By customer request a check was introduced for heritage coaches, which will not support collaboration, to filter these out for collaboration operations. Depending on the complexity of the process design, this heritage coach check can be expensive. Therefore an option will be introduced for the case that no heritage coaches are used, to skip the search. The search can be identified by the following trace entries: com.ibm.bpm.auth.AuthorizationForCollaboration isCollaborationPossible
Local fix
The workaround is based on placing a heritage coach in the top most human service. It is not required to be wired. By this a heritage coach will be immediately found and a tree search can be skipped. This will however disable the collaboration feature completely for the underlying coaches.
Problem summary
PERFORMANCE IMPROVEMENT FOR THE COLLABORATION FEATURE PROBLEM DETAILED DESCRIPTION: Customers experience performance problems with BPM environments that have a large number of tasks. Investigation showed that time is lost during execution of the following method: [1/7/14 18:19:22:464 COT] 000000c6 wle > com.lombardisoftware.server.ejb.api.AuthorizationAPICore canExecuteTasksActions ENTRY ... [1/7/14 18:20:48:337 COT] 000000c6 wle < com.lombardisoftware.server.ejb.api.AuthorizationAPICore canExecuteTasksActions RETURN This is done for each task, slows down the environment and causes timeouts.
Problem conclusion
This fix introduces a new configuration setting that can be used to optimize authorization checks for task actions, depending on the fact whether Coach, Heritage Coach, or both features are used: <server merge="mergeChildren"> <allow-collaboration>never</allow-collaboration> </server> The possible values for that property are: checkForCoaches - default value, with this value the BPM system will check the model for indication if Coaches or Heritage Coaches are used, this is the most reliable option, but also the most expensive never - this value will disable collaboration actions system-wide, this is typically used if no Coaches are used in the models, this will lead to better performance compared to 'checkForCoaches' always - this value will enable collaboration actions system-wide, this is typically used if no Heritage Coaches are used in the models, this will lead to better performance compared to 'checkForCoaches' FIX AVAILABILITY: iFix for 8.0.1.1 is/will be available on Fix Central; search for APAR JR49113 at http://www.ibm.com/support/fixcentral/ iFix for 8.0.1.2 is/will be available on Fix Central; search for APAR JR49113 at http://www.ibm.com/support/fixcentral/ Fix is also targetted for inclusion in next fixpack for BPM 8.0.1 When obtaining any of the above fixes, be sure to download the accompanying readme, for itself, and any prerequisite fixes, and review them thoroughly.
