Error in getting XML input stream with Oracle Business Rules 12.2.1 by Jan van Zoggel

November 18, 2016 Leave a comment

When trying to compile a Oracle ACM/BPM 12.2.1 project (with Oracle Business Rules) the following message throws up: “Error in getting XML input stream”

When Oracle Business Rules 12.2.1 generates it’s default XSD it uses the full system path instead of a relative path for it’s imports. So make sure to manually change the import configuration. Read the complete article here.

What’s New!

  • New Pricing Metrics
  • Sample Apps
  • Process Conversations
  • Enhanced Local and Remote App Deployment
  • New Tablet App
  • Start Process App from Mobile

New Pricing Metrics:

PCS pricing has moved to a 3-tier hosted named user model to accommodate varying levels of process service interaction from those who require full access to composition and management capabilities, to participants assigned review and approval tasks, to those whose interactions are limited to making service requests. This new pricing model helps maintain competitive pricing in use cases where there are large numbers of casual users. Below are the subscription pricing details. Metered pricing uses the same metrics at 2x the cost.

Oracle Process Cloud:

· $100 per Hosted Named User per Month

· Defined as a named user who can access analytics, compose applications and manage lifecycle

· Required minimum of 10 Users, 12-Months minimum contract

· Requires Oracle Process Cloud – Participant User

Oracle Process Cloud – Participant User:

· $30 per Hosted Named User per Month

· Defined as a named user who can participate in process approvals and tracking

· Required minimum of 10 Users, 12-Months minimum contract

· Requires Oracle Process Cloud

Oracle Process Cloud – Invocation User:

· $3 per Hosted Named User per Month

· Defined as a named user who can initiate a process and query status and notifications

· No minimum required – minimum of 100 Users if purchased, 12-Months minimum contract

· Requires Oracle Process Cloud

Sample Apps:

Sample Apps provide a quick and easy way to create and configure fully functional Process Apps with minimal technical knowhow. PCS includes a catalog of predefined ready to run Sample Apps that can be used both to provide first time designers a quick introduction to creating Process Apps and Business IT users easy to configure tailor made apps for a variety of use cases. IT and partners can publish their Process Apps as Sample Apps with specific pre-defined configurations allowing Business IT to quickly create, configure and deploy tailor made Process Apps.

Process Conversations:

Process Apps now support the addition of a process level conversation within the context of assigned tasks to allow stakeholders and participants to collaborate and streamline getting work done. Process Conversations also support various options to configure process activity stream messages that automatically update the conversation with process milestones.

Enhanced Local and Remote App Deployment:

Process App deployment has been enhanced to support complete segregation of test and production data. Test and Player functionality has been simplified to allow designers to either step through the Process App one activity at a time or run the Process App from the Workspace in Test Mode to experience the app from the perspective of an end-user. Production deployment has been enhanced to support deploying the Process App to the local environment or directly to remote environments.

New Tablet App:

A new universal Process Mobile App now supports native tablet form factors for both iOS and Android platforms. The tablet app takes advantage of the larger screen real-estate to provide an improved experience for managing tasks and initiating process requests.

Start Process App from Mobile:

Process participants can now remotely initiation process requests directly from their mobile App. Onboard camera support allows the user to capture pictures that are uploaded to Documents Cloud Service and displayed in context to downstream task participants.

M2M, the Other IoT by Noel Portugal

November 17, 2016 Leave a comment

clip_image001

 

Before IoT became ‘The’ buzzword, there was M2M (machine to machine). Some industries still refer to IoT as M2M, but overall the term Internet of Things has become the norm. I like the term M2M because it describes better what IoT is meant to do: Machines talking to other machines.

This year our team once again participated in the AT&T Developer Summit 2016 hackathon. With M2M in our minds, we created a platform to allow machines and humans report extraordinary events in their neighborhood.  Whenever a new event was reported (by machine or human),  devices and people (notified by an app) connected to the platform could react accordingly.  We came with two possible use cases to showcase our idea.

Virtual Gated Community

Gated communities are a great commodity for those wanting to have privacy and security. The problem is that usually these communities come with a high price tag. So we came up with a turnkey solution for a virtual gate using M2M. We created a device using the Qualcomm DragonBoard 410c board with wifi and bluetooth capabilities. We used a common motion sensor and a camera to detect cars and people not belonging to the neighborhood. Then, we used Bluetooth beacons that could be placed in at the resident keychains. When a resident drove (or walked) by the virtual gate, it would not trigger the automated picture and report to the system, but if someone without the Bluetooth beacon drove by, the system will log and report it.

Doing performance measurements of an OSB Proxy Service by programmatically extracting performance metrics via the ServiceDomainMBean and presenting them as an image via a PowerPoint VBA module by Marc Lameriks

November 16, 2016 Leave a comment

clip_image002

 

This article explains how the process of doing performance measurements of an OSB Proxy Service and presenting them in a “performance analysis document” was partly automated. After running a SoapUI based Test Step (sending a request to the service), extracting the service performance metrics was done by using the ServiceDomainMBean in the public API of the Oracle Service Bus. These service performance metrics can be seen in the Oracle Service Bus Console via the Service Monitoring Details. Furthermore this article explains how these service performance metrics are used by a PowerPoint VBA module and slide with placeholders, to generate an image, using injected service performance metric values. This image is used to present the measurements in a “performance analysis document”.

Performance issues

In a web application we had performance issues in a page where data was being shown that was loaded using a web service (deployed on Oracle Service Bus 11gR1). In the web page, an application user can fill in some search criteria and when a search button is pressed, data is being retrieved (from a database) , via the MyProxyService, and shown on the page in table format.

Performance analysis document

Based on knowledge about the data, the business owner of the application, put together a number of test cases that should be used to do performance measurements, in order to determine if the performance requirements are met. All in all there were 9 different test cases. For some of these test cases, data was being retrieved for example concerning a period of 2 weeks and for others a period of 2 months.

Because it was not certain what caused the lack of performance, besides the front-end, also the back-end OSB Proxy Service was to be investigated and performance measurement results were to be documented (in the “performance analysis document ”). It was known from the start that once the problem was pinpointed and a solution was chosen and put in place, again performance measurements should be carried out and the results were again to be documented.

Patching JDeveloper 12.1.3 for OSB and SOA by Jon Petter Hjulstad Keeping your JDeveloper SOA/OSB Quickstart environment up to date

November 15, 2016 Leave a comment

clip_image002

 

Oracle released new patches some weeks ago, and to keep your JDeveloper updated for SOA Suite and Oracle Service Bus there are three products you should patch:

  • Oracle SOA Suite
  • Oracle Service Bus
  • Weblogic

When you search My Oracle Support (MOS) for patches – you can see which ones are the recommended ones. There are also notes in MOS which are updated regularly:

  • OSB 11g and 12c: Bundle Patch Reference (Doc ID 1499170.1)
  • SOA 11g and 12c: Bundle Patch Reference (Doc ID 1485949.1)
  • Master Note on WebLogic Server Patch Set Updates (PSUs) (Doc ID 1470197.1)

In the environment I used for this example. Patch 19707784: SOA Bundle Patch 12.1.3.0.1 was applied before. This will be detected by OPatch, and that patch will be rolled back.

The patching is simplified in the 12c-version, because now there is only one OPatch-folder to care about (in version 11 there were one per product). You can read more about it here: Oracle Documentation link

For each patch there is a README.txt, whick you should read. It contains Pre-Installation Instructions, Install and Post-Instructions. For the SOA-patch, you should look through the steps for the Post-steps

I use Windows environment in this example, so I set the environment variables first (run as Administrator): Read the complete article here.

Connect and consume data assets with OSB12c and WebCenter Sites 11g using the REST api by Fabio Persico

November 12, 2016 Leave a comment

clip_image002

 

In one of the project I’ve worked on, I configured an automatic creation/update and delete of assets in WebCenter Sites 11g using its REST api via OSB.
The configuration is a bit tricky so I want to share the solution.
I am not giving the details step by step of how this can be implemented as I am sharing the code, btw I’ll explain the main important concept.

What it is needed for this tip:
  • JDeveloper 12.1.3 (SOA Quick start version)
  • An account with read/write right permission in a WebCenter Sites server
  • The AssetType created in Sites
OSB Services Implemented

The Pipeline in the project contains the below services: Read the complete article here.

Service Bus 12.2.1 JVM Settings: PermSize, Heap, Non-Heap, and ResourceManagement by Frank Munz

November 11, 2016 Leave a comment

clip_image002

Oracle Service Bus comes with JVM settings that cause questions to some customers. This posting provides answers to the most common questions I discussed in workshops or received so far.

Warning about PermSize Option

Question 1: “I see the following warning:

Java HotSpot(TM) 64-Bit Server VM warning: ignoring option MaxPermSize=1024m; support was removed in 8

Does that mean that Oracle generates the startup scripts with wrong JVM flags?”

Answer: With Oracle JVM 8 the permanent space was removed. Not having a perm space was a JRockit “feature” that has been ported over to the Oracle JVM. The warnings of course are harmless. Startup scripts for WebLogic only domains are generated correctly for WebLogic 12.2.1. So Oracle needs to change this for OSB domains and they know about it.

Heap Size

Question 2: “How big is Oracle Service Bus now? I used to be able to create and run a cluster on my laptop with earlier versions but now I run into resource problems.”

Answer: Default startup parameters are: -Xms1024m -Xmx2048m, i.e. minimum heap size is 1 GB, maximum heap size is 2 GB. Hence you should expect your process size to be larger than 1 GB right from the start. Read the complete article here.

DB Link integration or ESB based by Dalibor Blazevic

November 10, 2016 Leave a comment

 clip_image002

Pros. and Cons.

As the state owned electric company of one East European country is undergoing transformation to conform to EU standards it has been transformed from one monolith organization to different smaller entities, each with his own task. Furthermore these entities have been further subdivided based on a region. Also the new players arrived on the market as the law has ben changed to accommodate that possibility. Now the different organizations that emerged from this dividing and subdividing have not been able to use a single monolith ERP and billing application to process and accommodate all possible use cases that the process of selling, producing, provisioning, and supplying electric current, requires. Different companies have been allowed to use their own IT systems to satisfy their business needs. IT systems have become heterogeneous. However because of the need for cooperation and data sharing between these organizations as both required by law and by business needs, numerous use cases requiring integration have emerged. Organizations are faced faced with dilemma whether to invest in ESB based integration solution or use, from his point of view, simpler and chipper solution. Point-to-Point Solution that is based on numerous database links between different heterogeneous databases.

Integration entities

Beside the needs to exchange data between two organizations doing business in different regions, most of the data exchange occurs between entities doing cooperative efforts from selling to provisioning of electric current to the end users. First of all the end user has open possibility to buy electric current from different sellers based on the different package offering provided by seller. On the other hand seller has the possibility to choose from which producer to buy electric current based on the current market prices for electric production and future trend analyses. That means that distribution channel from the producer to the end user does not have to be constant as producer, provisioning channel from producer to distributor and supplier, and in some cases also supplier himself might get changed during the duration of the contract period. Numerous use cases are needed to satisfy previously mentioned requirements and we are going to mention end explain some of them and present them in both use case UML diagrams and possible implementation outcomes.

Use cases

From the moment when the end-user signs contract with the supplier to the moment when the electric current in delivered to the end user there are several basic use cases.

Use case 1: Sending user data to supplier

As the seller of the electric current does not have to be business that is directly related with provisioning and distributing of the electric current, electric current supply can be part of the bigger packages that can include e.g. telephone plus Internet plus TV plus electric current in the same package.
