#316 - BPM Workspace iPad App

Now available via the App Store -



















I finally updated my iPad to iOS 7, thus enabling me to download the Oracle BPM Workspace App which gives us a subset of workspace functionality on the iPad.

Here are the steps to getting the whole thing up and running -

1, Install BPM PS6
2. Install the bp3 patch - 18072286
3. Download the app to your iDevice
4. Configure - Click on iPad --> Settings --> BPM --> set the server and port entries to point to your BPM Server.
5. Create a simple order approvals process --> just containing 1 human task
6. Auto-generate ADF task form
7. Deploy all
8. Create a test instance
9. Login to the iPad BPM app e.g. weblogic/welcome1
10. Approve Orders to your heart's content.

#315 BPM Re-deployment, keeping running instance on.

This post covers what can happen internally when you re-deploy a BPM process, keeping running instance on. Essentially I deploy the process below, create an instance. I then remove the script task and redeploy, keeping running instances on. The post details what goes on internally to manage this.

Simple example -













I deploy and create an instance of the process -

I check the trace in EM


















Process started at 8:57 am
Check the work_item table, note the 2 rows with state 3 (OPEN, Pending Completion)













Note the expiration time for the Timer (8:57 + 70 minutes)

Now delete the script task from the process and redeploy - keep instances on

































Re-visit the work_item table - you will see that the state is still set to 3.

Now I use the following SQL to check the WF_TASK table -

select wf.instanceid,
  wf.taskid,
  wf.tasknumber,
  wf.ecid,
  wf.state,
  wf.componentname,
  wf.componenttype,
  wf.updatedDate,
  wf.thread,
  wf.parentthread
from wftask wf
where
  wf.state in (
    'SUSPENDED',
    'PENDING_MIGRATION',
    'PENDING_MIGRATION_SUSPENDED',
    'ERRORED',
    'ALERTED',
    'STALE')
    order by updatedDate desc;












Three rows – thread 0 is a shadow process –
The other 2 are for the parallel gateway paths –
1 - human task
2 - timer

























Open workspace as Admin user –go to Process Tracking
























Migrate the instance


















Re-check the work_item table






There are now 4 rows – 2 for each activity (Human task & Timer)
The originals are from 08:57 and now have the state 8 (Closed_Cancelled)

2 new rows with state = 3 have been created. The new timer expiry time is now –





Here in the trace from em –















The take-away here is - don't get confused if you see the state of the work_item changed to 8. The relevant new rows with state 3 will have been crested.

#311 Happy St. Patrick's Day from Maui

Off for the month of March for some well deserved R&R.
Spend today on the well worn road to Hana, instead of parading like the rest of the Irish diaspora.


So until April!
