Release Version : 11.1.0_hotfix14
Release Date : October 2009
========================================================
This hotfix is cumulative with all previous v11.1.0.x hotfixes. It
includes the iProcess Client, iProcess Workspace (Browser) Components,
Java Action Processor, and .NET Action Processor.
Note - There were no hotfixes 02, 03, 04, 11, nor 12 of this product released.
========================================================
Closed Issues in 11.1.0_Hotfix14
Defect Id: 41528
Note - This hotfix applies MR 41528 to the .NET Action Processor only.
When a user selects the "Open First Available Work Item" or "Open Next
Available Work Item" function in the TIBCO iProcess Workspace (Browser), a
"Work item already locked" error can appear. This error can appear because
the work item to open is being selected from the work item list on the client,
which is a "snap shot" and doesn't reflect locks that have occurred by other
users on work items in that snap shot.
Implemented. To rectify this issue, an "AtomicServerLock" configuration
parameter has been added to the TIBCO iProcess Workspace (Browser) in the
config.xml file. This new parameter allows you to specify that the selection
of the work item to lock occur on the server instead of on the client, ensuring
that the work item the server attempts to lock is available to lock.
Note that to use this "atomic server lock" feature, your TIBCO iProcess
Objects Server must have MR 38404 implemented. Also note that if your TIBCO
iProcess Objects Server also contains MR 41569, the operation of this feature
differs, as described below.
The new configuration parameter works as follows:
- AtomicServerLock - This parameter is used to cause the selection of the
work item to lock to occur on the server (instead of on the client) when
using the "Open First Available Work Item" and "Open Next Available Work
Item" functions.
This parameter has the following two attributes:
- supported:
- If set to "true", the work item selection for the aforementioned
functions occurs on the server.
- If set to "false", the work item selection occurs on the client.
If you set supported = "false", the behavior is the same as prior
to this fix, i.e., a "Work item already locked" error may occur
when the "Open First Available Work Item" or "Open Next Available
Work Item" function is used. (This provides backward
compatibility for TIBCO iProcess Object Servers that don't have
MR 38404.)
- refresh:
- If set to "true", the snap shot of the work items is refreshed
prior to the iProcess Workspace (Browser) requesting that the
server atomically lock the work item.
- If set to "false", the snap shot of the work items is not
refreshed prior to the iProcess Workspace (Browser) requesting
that the server atomically lock the work item.
The following lists the reasons you may want to set the "refresh" attribute to
"true" or "false" when using the atomic server lock feature (i.e.,
supported = "true"), depending on whether your TIBCO iProcess Objects Server
has only MR 38404, or both MR 38404 and MR 41569:
- Your TIBCO iProcess Objects Server has only MR 38404:
- If you are only concerned with ensuring that the server atomically
lock the first available work item in the snap shot for the "Open
First Available Work Item" and "Open Next Available Work Item"
functions, set the attributes as follows:
- supported = "true"
- refresh = "false"
- If you want to ensure that the atomic server lock includes new work
items, and excludes work items that would no longer be in the work
queue because they no longer match the filter, set the attributes
as follows:
- supported = "true"
- refresh = "true"
- Your TIBCO iProcess Objects Server has both MR 38404 and MR 41569:
- If you are not concerned that the atomic server lock includes new
work items that have arrived in the work queue since the last
refresh, set the attributes as follows:
- supported = "true"
- refresh = "false"
- If you also want to ensure that the snap shot be refreshed to
include new work items, before the server atomically locks a
work item when using the aforementioned functions, set the
attributes as follows:
- supported = "true"
- refresh = "true"
Note that when your server has MR 41569, the server also re-applies
the filter that was specified on the work queue, to the snap shot,
prior to selecting the work item. Therefore, work items in the
snap shot that would no longer match the filter are excluded by
the atomic server lock.
Additional notes concerning the "atomic server lock" feature:
- There is a cost to setting refresh = "true" -- the work item list is
refreshed every time the user selects the "Open First Available Work
Item" or "Open Next Available Work Item" function. Therefore, you should
set refresh = "true" only if a refresh is needed.
- Your TIBCO iProcess Engine's "WIS_QCHANGE_EXTENDED_CHECK" process
attribute must be set to 1.
- If you are using a TIBCO iProcess Objects Server that does not support
the "atomic server lock" feature (i.e., it does not have MR 38404),
and a user attempts to use the "Open First Available Work Item" or
"Open Next Available Work Item" function, a "Lock First Work Item not
supported" message is displayed.
