Oracle Integration Cloud: New! The Data Mapper Activity

In a previous blog I discussed a work-around for not having a Script activity in Oracle Integration Cloud's Process Builder. In this blog I will discuss another work-around which is actually not a work-around, but the real thing: the Data Mapper!

As you can read in a previous blog about the matter, not having the equivalent of the Script activity of the on-premise BPM Suite, was an omission that we often had to find (more...)

Deploying my first Pivotal Container Service (PKS) workload to my PKS cluster

If you followed along on the previous blogs you would of installed PKS 1.0 on GCP (Google Cloud Platform) and created your first PKS cluster and wired it into kubectl as well as provided an external load balancer as per the previous two posts.

Wiring kubectl / Setup external LB on GCP into Pivotal Container Service (PKS) clusters to get started

Now that I have PCF 2.1 running with PKS 1.0 installed and a cluster up and running how would I get started accessing that cluster? Here are the steps for GCP (Google Cloud Platform) install of PCF 2.1 with PKS 1.0. It goes through the requirements around an External LB for the cluster as well as wiring kubectl into the cluster to get started creating deployments.

Install Pivotal Container Service (PKS) on GCP and getting started

With the release of Pivotal Cloud Foundry 2.1 (PCF) I decided this time to install Pivotal Application Service (PAS) as well as Pivotal Container Service (PKS) using the one Bosh Director which isn't recommended for production installs BUT ok for dev installs. Once installed you will have both the PAS tile and PKS tile as shown below.

So here is how to get started with PKS once it's installed

1. Create (more...)

Comparing Intent Classification in TensorFlow and Oracle Chatbot

I have created sample set of intents with phrases (five phrases per intent, and ten intents). Using this set of data to train and build classification model with TensorFlow and Oracle Chatbot machine learning. Once model is trained, classifying identical sample phrases with both TensorFlow and Oracle Chatbot to compare results. Using Oracle Chatbot with both Linguistic and Machine Learning models.

Summary:

1. Overall TensorFlow model performs better. The main reason for this - I (more...)

Socket.IO Integration with Oracle JET

Socket.IO is a JavaScript library for realtime web applications. It comes in two parts - a client-side library that runs in the browser and a server-side library for Node.js. In this post I will walk you through complete integration scenario with Oracle JET.

Here you can see it in action. Send Event button from JET - sends message through Socket.IO to Node.js server side. Message is handled on server side and (more...)

ADF on Docker – Java Memory Limit Tuning for JVM

It might look like a challenge to run Java in Docker environment, by default Java is not aware of Docker memory limits. Check this article for example - Java inside docker: What you must know to not FAIL.  I was able to run WebLogic and ADF (Essential WebLogic Tuning to Run on Docker and Avoid OOM) on Docker previously without Java memory issues, using JAVA_OPTIONS=-XX:+UnlockCommercialFeatures -XX:+ResourceManagement -XX:+UseG1GC. However after Docker upgrade (more...)

Oracle JET Offline Persistence Toolkit – Offline Update Handling

Oracle JET Offline Persistence Toolkit supports offline update, create and delete operations. In this post I will describe update use case. Read previous post related to offline toolkit, where I explain how to handle REST pagination, querying and shredding - REST Paging Support by Oracle Offline Persistence in JET.

This gif shows scenario, where we go to offline mode and then changing data in multiple rows. Data update happens offline and each PATCH request is (more...)

Oracle Integration Cloud: Customer Managed & Patching

Currently the Oracle Integration Cloud (OIC) only comes as "customer managed". Among others this means that you as a customer have access to management consoles. It also means that you determine when to apply patches, as Oracle does not do that for you. The following describes how easy that is.

Oracle Cloud solutions can come in two flavors: Oracle Managed and Customer Managed. The first means that maintenance, including patching is done by Oracle. (more...)

Oracle Integration Cloud Tips & Trics: Work-around for no Script Activity

Oracle Process Cloud Services (PCS) nor the Process Builder in Oracle Integration Cloud (OIC) have a Script activity like there is in (on-premise) BPM Suite. In the BPM Suite you can use a Script activity for data mappings as well as Groovy. That OIC does not support Groovy is by design as the idea is to keep it as simple as possible. However missing the data mapping feature of the Script activity can make it (more...)

ADF Declarative Component Example

ADF Declarative Component support is popular ADF framework feature, but in this post I would like to explain it from slightly different angle. I will show how to pass ADF binding and Java bean objects into component through properties, in these cases when component must show data from ADF bindings, such approach could offer robustness and simplify component development.

This is component implemented in the sample app - choice list renders data from ADF LOV (more...)

Pivotal Cloud Foundry Healthwatch for Pivotal Cloud Foundry 2.0 on GCP

I decided to eventually install PCF Healthwatch on my Google Cloud Platform PCF 2.0 instance. Installing it is straight forward using Ops Manager UI and once installed it will look like this.

Note: This is PCF 2.0 on GCP


Once installed the application for the Web UI end point would be as follows. The login username and password is the UAA admin user . By default the property "healthwatch.read" credential is given (more...)

Find In Cache By Key ADF BC API Method Usage

What if you need to verify - if row with given key exists in fetched rowset? This could be useful while implementing validation logic. ADF BC API method findByKey - will trigger SQL call and fetch row from DB, if row with given key doesn't exist in fetched rowset. Luckily there is ADF BC API method called findInCacheByKey, this method only checks for row in fetched rowset, without going to DB - very convenient (more...)

Just gave CFDEV a quick test and it’s easy and includes BOSH!!!!

CF Dev is a new distribution of Cloud Foundry designed to run on a developer’s laptop or workstation using native hypervisors and a fully functional BOSH Director.

I decided to give it a test run today and it's fast and easy full CF experience deployed through the CF CLI plugin as described in the GitHub project

Spring boot 2 Actuator Support and Pivotal Cloud Foundry 2.0

With Spring Boot Actuator you get production-ready features to your application. The main benefit of this library is that we can get production grade tools without having to actually implement these features ourselves.

Actuator is mainly used to expose operational information about the running application – health, metrics, info, dump, env, etc. It uses HTTP endpoints or JMX beans to enable us to interact with it.

In this post we will show how Spring Boot (more...)

Classification – Machine Learning Chatbot with TensorFlow

Visual conversation flow is a first thing to create, when you want to build chatbot. Such flow will help to define proper set of intents along with dialog path. Otherwise it is very easy to get lost in conversation transitions and this will lead to chatbot implementation failure. Our chatbot for medical system doesn't make any decisions, instead it helps user to work with enterprise system. It gets user input and during conversation leads to (more...)

Microservices with Oracle ADF Remote Regions

ADF remote regions - functionality available in the latest ADF 12c versions. ADF remote region runs on different server and content is delivered to consuming module through ADF remote region servlet. This allows to decouple large enterprise system into separate modules, each running independently on separate servers. Gained advantage - system becomes more scalable and reliable, even if several modules will be down, system will continue to be functional.

Concept of ADF remote regions, reminds (more...)

Shredding and Querying with Oracle Offline Persistence in JET

I think offline functionality topic should become a trend in the future. Its great that Oracle already provides solution for offline - Oracle Offline Persistence toolkit. This is my second post related to offline support, read previous post - Oracle Offline Persistence Toolkit - Simple GET Response Example with JET. I have tested and explained with sample app how it works to handle simple GET response offline. While today I would like to go one (more...)
