BPM Workspace Login with libOVD and LDAP, Part 2: Login by Siming Mu

May 7, 2015 Leave a comment

 

clip_image002Introduction

In Part 1, we looked at the initialization of libOVD at server startup. Now let’s examine what happens inside libOVD when you actually click on the login button in BPM Workspace. Again, we are looking at BPM 11g PS5 BP7 with Patch 17315336.

The Workspace login is a two step process. The first step is checking the username and password against the LDAP. This step is performed in WLS security layer rather than the JPS layer. This means even if you turn on tracing in libOVD, you won’t see any trace log message related to this step.

The second step starts after the user credentials are successfully verified. In this step, the Workspace first constructs a Workflow context object, which triggers a user lookup query against the LDAP, and then it makes a request to the BPM server which invokes the follow method:

oracle.bpel.services.workflow.common.provider.WorkflowWSProvider.processMessage

Top 10 Things You Should Know About BPM 11g/12c by Mark Foster

May 4, 2015 1 Comment

 

clip_image001With the help of my A-Team colleagues (Sushil Shukla, Siming Mu, John Featherly, Pete Farkas), and based on collective experiences visiting numerous BPM customers worldwide, I have put together my “Top 10″ list of things everyone should know when embarking on a BPM project.

You might agree, you might disagree, most of all, feel free to comment.

1. Auditing

BPM provides the business with extremely detailed visibility of runtime instances through its powerful auditing capabilities.

HOWEVER…

This comes at a cost: detailed auditing requires frequent inserts into the SOAINFRA database increasing the likelihood of contention and causing significant database growth. As volume increases it is almost always the case that the consequences of Auditing produce the first bottleneck.

BUT…

Auditing can be tuned down where appropriate and purge scripts can remediate database growth

SEE…

Auditing Demystified

2. Payload Size

It can often be simpler at the time of BPM process design to have one large payload schema that includes all elements for every possible interaction within the lifetime of an instance, and pass this everywhere within the instance, including to human tasks and their UIs.

HOWEVER…

The cost of this, both at runtime and in terms of the number and size of database rows, can be large. The whole payload must be written to SOAINFRA database at dehydration points within the lifetime of a process instance & in-between these dehydration points, data objects associated with this payload are held in memory.

BUT…

Appropriate design of the payload schema (flatter & simpler) can reduce the size considerably. The optimal solution would be to pass only key-values in the payload and retrieve detail values as-and-when needed inside the process, however this can lead to over-complicating the process design with technical services. A sensible balance is always the best approach.

SEE…

XML_DOCUMENT Table Growth

3. Partitioning / Purging

BPM audits heavily, this can be extremely useful for business insight

HOWEVER…

The SOAINFRA database growth can be larger than expected

BUT…

Partitioning & purging are critical to limiting database growth. Test purging thoroughly as part of a normal stress/load test cycle. Determine whether “loop purge” outside of the online window is sufficient, if not consider also using “parallel purge” during quiet periods during the online day. Partitioning is a good option in most cases, in 11g SOAINFRA must be partitioned post-installation but in 12c it is an installation option.

SEE…

SOA 11g Database Growth Management Strategy Paper

SOA Partitioning

4. Negative Testing

SOA Suite provides a comprehensive fault policy framework & BPM has inbuilt fault-handling constructs, allowing the vast majority of technical and business exceptions to be handled gracefully.

HOWEVER…

Failure to properly negative test potential exceptions, individually & in bulk, can lead to inadequate operational guidelines & faults occurring in production which can be hard to recover.

BUT… Read the complete article here

The first BPMN process by Maverick

May 3, 2015 Leave a comment

 

clip_image002

I know I’m a bit late on this article, but my presence in the Middle East had more (positive) impact than I anticipated, so I got tied up at work.

Anyway, let’s finally start to use Oracle’s BPM Composer to model our “Request a parking space” process.

As the Akino Fishing Co is a series focused on the Business User, we’ll try to keep our articles as Zero-Code as possible.

Finally… Hands-on!

We’ll start by logging on to BPM Composer

Oracle BPM Composer Login Screen

After logging in we are taken into the Process Spaces screen. Here, we’ll create a Space for our BPM Initiative. A Space is an container were you group and keep your Business Architecture (BA) and BPMN projects.

You can create as much spaces as you want, to organize your Business Architecture and BPMN projects the way you think it’s best. However, a project that belongs to a given space can’t be “seen” in other spaces, so take that into account. For the purpose of our article, we’ll be using just one space for all processes.

Patch SOA/BPM VM to WebCenter 11.1.1.8 by The Cattle Crew

April 1, 2015 Leave a comment

 

clip_image002At OTN you can find the latest 11g SOA/BPM Virtual Machine (VM) which also contains Webcenter. Unfortunately, Webcenter has been added in version 11.1.1.7 to that VM; as there are major enhancements in Webcenter 11.1.1.8 it generally makes sense to upgrade the VM to that version.

At the Oracle website a documentation for upgrading from 11.1.1.7 to 11.1.1.8 can be found. In this post I want to describe which steps of the update guide I actually executed in order to upgrade my VM and which ones I skipped as they seem to be optional.

The particular steps are also described in full detail here.

Pre-Patching Tasks

I skipped all pre-patching tasks, as we’re starting with a VM that does not contain any data so far and which already contains an up to date Weblogic installation. Read the complete article here.

Creating Custom BPM Work List for Human Tasks based in ADF by Mark Peterson

March 30, 2015 Leave a comment

 

clip_image002

If you ever need a custom work list and need to open the human task from this list, then this blog can help you. All you really need to do is find the list of tasks and create the URL that opens the task from the custom work list. This is not as straightforward as it seems since the URL contains some dynamic fields that you will need to derive from information about the tasks.

The need for a custom work list usually involves some sort of relationship between instances in a process, or between tasks in different processes such that the OOTB functionality of the BPM workspace is not sufficient. The user wants to see a logical grouping of tasks or between parent and child tasks. These tasks should be shown grouped together. These tasks can be shown in a table or tree format and each task should have a link to click on to open the task directly from the form. This is an example of such a list and grouping. Read the complete article here.

BPM Authentication On Behalf Business User from ADF by Andrejus Baranovskis

March 28, 2015 Leave a comment

 

clip_image002This is the next post in the series of ADF/BPM integration, check previous post available here – Dynamic ADF Buttons Solution for Oracle BPM Outcomes. Here I’m going to describe how you could authenticate with BPM from ADF through a proxy user, on top you could apply only business user name, password will not be required.
There is API method available – authenticateOnBehalf(context, userName), you must have a valid connection context created and with authenticateOnBehalf method you could set to use any valid user name, instead of proxy user. Here is the example for Workflow Context: Read the complete article here.

BPM 11g: Instance Patching Revisited: Inability to Create New Instances by Mark Foster

January 27, 2015 Leave a comment

 

clip_image002Introduction

Back in 2012 after the release of BPM 11g PS4FP I wrote a blog entry on Instance Patching, what it was and how it worked.

Remember, instance patching is redeployment of a composite on the same Revision ID with “keep running instances” option, as opposed to instance migration which follows deployment of a new composite with a new Revision ID and selected instances migrated from the old to the new revision.

I’ve decided to revisit the subject in a little more detail on the back of an issue a customer had with instance patching…. they’d redeployed a composite after making a very small “compatible” change to the BPM process and subsequently found that they could not instantiate new instances. This blog will detail why this situation happened and how to recover from it.

Walk-through of the Issue

Revisit the Process

From the previous blog entry we had a very simple process with three human activities and file write….

….we instantiated several instances and progressed them to various different human activities… Read the complete article here.
