How to start a workflow by an event

Question

Did somebody know how to start an OWB workflow after an event occur ?
In my application, the OWB workflow must start (and import data) after a record is insert in one of my application database table. Actually, I schedule a job to look in that table every single minute. The problem is that every minute, a connection is open and close on the application database. Also, the user have to wait for one minute (at most) before is job begin to be process. Can someone have a way to start OWB on event by using trigger, queue or something else ?
Thank you,

Answer 1

owf(your_OWF).wf_engine.LaunchProcess(item_type, item_key, process_name);
If your process is defined as:
Module: PRC_MODULE
Process_flow_package: PRC_PACK
Process_name: PROCESS
then ITEM_TYPE is PRC_PACK,
ITEM_KEY can be anything, like p_process_name||'_'|| SYSDATE to make sure it does not get doubled,
and process_name is PROCESS.
So when you call this function it would look like this:
owf(your_OWF).wf_engine.LaunchProcess('PRC_PACK', 'PROCESS_24072009120000', 'PROCESS');
