If anything most irritating in IBM BPM product is its lake of documentation of user manual for the product. I have spend long time on finding information about different component of IBM BPM and believe me its bit tough to find good article or manual.
Yesterday, I found a very good article on IBM BPM Event Manager by BP3 and it has almost everything we want to know about IBM BPM Event Manager.
Which includes topics like below.

Event Manager Design
In the Event Manager (EM) design the database the master of everything.
The important Event Manager related table in BPMDB are:
The important Event Manager related table in BPMDB are:
lsw_em_instance - A row for each EM scheduler.lsw_em_task - A row for each non-completed task, includes a reference to lsw_em_instance to indicate which scheduler owns each task.lsw_em_task_keyword - One-to-many table mapping a task to its associated keywordslsw_em_sync_queue - A row for each sync queue, includes a reference to lsw_em_instance to indicate which scheduler owns each sync queue.lsw_uca_blackout - A row for each blackout period, including the next transitions into and out of blackout
The database knows what schedulers exist, what sync queues exist, what tasks exist, what states the tasks are in, etc. So, basically Event Manager uses the database’s transaction guarantees as much as possible to ensure a consistent view across all machines in a cluster. In addition, Event Manager uses the database’s system clock as the master, to avoid problems with time-syncing among machines in a cluster.
