Demo: Version Control for PL/SQL in 30 Minutes

Hi Everyone! We prepared a 30 minute demo video to show you how Gitora can help you manage your PL/SQL code base. Check it out below:

Configuring Spring Boot Actuator information in Pivotal Cloud Foundry 1.9 Applications Manager

With the release of Pivotal Cloud Foundry 1.9 we added "Spring Boot Actuator In PCF" through Applications Manager Web UI. In this example below I will show what config you need on your application side to get Apps Manager Web UI to show you this information.

Spring Boot Actuator exposes information about a running Spring Boot application via an http endpoint. Get useful diagnostics about an app programmatically using these RESTful APIs:  health, git (more...)

Spring Boot Application Consuming NAB FxRates API

National Australia Bank (NAB) recently released a set of BETA API's as per the link below.

https://developer.nab.com.au/

The following example is a Spring Boot Application that consumes the FxRates API. It's all documented on GitHub and you will need a NAB API key to run this demo. It can run stand alone as a FAT JAR through Spring Boot or deployed to Cloud Foundry, instructions appear for both.

Oracle JET Router API Example

One of the examples of JET Router API usage - sign-in/sign-out implementation. After sign-in we need to change menu structure and allow access to application modules, on sign-out menu structure should be changed again. JET Router API allows to manage application navigation and menu structure from JavaScript. Check complete API methods list here - JSDoc: Class: Router.

Sample application code is available on GitHub - JETPlaygroundApp. This application is generated with JET NavDrawer template and (more...)

Oracle ADF – Strategic Oracle Technology

Happy New Year !

There is update for Oracle ADF Statement of Direction dated to November 2016:


You can read full document on Oracle Support site, search for document ID 1985782.1.

To summarise outlined roadmap for Oracle ADF:

1. Oracle continues its commitment to Oracle ADF as a strategic technology

2. Oracle ADF will bring new technologies minimising the negative effect of change (recent examples - ADF BC REST, HTML5 support)

3. In future versions (more...)

PostgreSQL for Oracle Developers and DBA’s

PostgreSQL is not very well known among Oracle developers and DBA’s. Yet, the skill set of an Oracle developer or a DBA is easily portable to PostgreSQL.
There is no one better than Joshua D. Drake to teach you PostgreSQL and show you how you can migrate from Oracle to PostgreSQL.
Attend Joshua's free webinar and earn how you can benefit from PostgreSQL, the leading free and open source alternative to the Oracle Database.

NetBeans Git Client for JET Versioning and Oracle Developer Cloud Service

I should say I'm happy with how NetBeans Git client works. It offers good performance and resolves conflicts pretty well.

It shows a list of pending changes and also changes colour for changed file name:


Changes can be committed into local repository through informative wizard:


File changes are displayed in very clear way, easy to understand them:


All local changes can be pushed to Oracle Developer Cloud Service Git (or other repository):

ADF BC REST 12.2.1.2 Custom Method JDeveloper Workaround

Some of you who would try to implement custom method with ADF BC REST may face JDeveloper 12.2.1.2 wizard issue. JDeveloper 12.2.1.2 wizard is refusing to register ADF BC REST custom method, but it works perfectly on ADF runtime. Seems to be JDeveloper 12.2.1.1 - 12.2.1.2 bug. There is a workaround to modify REST service configuration manually and include custom method binding.

Success Story: Version Control for PL/SQL

It’s been a little over three months since we released Gitora 2.0 and the first success stories have started to emerge. Here is one of them:


Rhenus Logistics, the leading logistics company from Germany uses Gitora to manage their Oracle Database.

Problem

Rhenus IT uses both Java and PL/SQL to serve their users and customers. They have a team of about 10 PL/SQL developers. The team manages more than 20,000 database packages, views, functions, (more...)

ADF REST Framework Version 2 (and later) – 12.2.1.2

While building our new Oracle Cloud application with ADF BC REST and JET, I have discovered not announced feature in ADF BC REST 12.2.1.2. Starting from 12.2.1.2 ADF BC REST offers runtime versions. This is configurable in adf-config.xml file or could be provided through REST request header. ADF 12.2.1.2 supports version 1, 2 and 3. Version 2 offers better query support, while version 3 provides (more...)

Oracle JDeveloper (SOA and BPM) 12c (12.2.1.2.0) – Download Temporarily Not Available

If you try to download JDeveloper (as well as SOA Suite or BPM Suite) from OTN - you will see a message on OTN download section - "This page is temporarily not available we'll be back soon".

You should not worry, as per Shay Shmeltzer answer on OTN Forum - "We discovered an issue with the installer - we are working to fix this. Once we have the updated installer we'll update (more...)

Skip LOV Validation for ADF BC Bulk Insert

This post is about ADF BC LOV. I will describe how you could optimize bulk insert of new rows into VO, when some of the attributes are assigned with LOVs. By default ADF would validate new row attribute value through LOV (LOV Validation and Programmatic Row Insert Performance) for each new row. This will lead to bad performance, especially if you insert a set of new rows programmatically - there will be multiple (more...)

No, being wary doesn’t hurt Java. A comment about Java licensing.

Screenshot from the Oracle Website (source)
So. Oracle want's to make money from Java. And The Register published a very polarising piece with a super catchy title about it. According to their sources, "Oracle is massively ramping up audits of Java customers it claims are in breach of its licences". While the Twitter-verse went ballistic about people criticising Oracle's behaviour, I want to take a minute to recap, why I am against this (more...)

Script to tally Application Instance Counts for Pivotal Cloud Foundry

I was recently asked how to determine how many application instances exist in a given ORG at a point in time. The script below can do this using CF CURL command which means you must be logged into your Pivotal Cloud Foundry instance for this to work. You can use the CF REST API itself but I find the CF CURL much easier.

CF REST API https://apidocs.cloudfoundry.org/249/

The script below is assuming an (more...)

JET Application – Generate with Yeoman – Debug in NetBeans

Let's take a look today how to debug JET application which is initially generated with Yeoman. We could debug in NetBeans, but by default application generated with Yeoman is not runnable in NetBeans, we need to add manually some config files - I will describe how. Also note - JET application created with NetBeans can't be directly served with grunt from command line, it also would require manual changes in the config. It would be (more...)

Spring Boot with Feign and Twitter Typeahead JS library

I previously blogged about a demo using Spring Boot and Feign making an external based REST call to a service I had created. The real purpose of that demo "http://theblasfrompas.blogspot.com.au/2016/12/spring-boot-feign-client-accessing.html" was to use Twitter Typeahead for auto completion which is the demo on Github below. The returned data is now used in an INPUT text input for auto completion as the user types in the Country Name

Early ADF Model Update with Process Updates Method

This use case specifically useful for ADF UI value change listener. If there is business logic to be invoked when field value is changed, we can can call ADF BC custom method from assigned value change listener. However new value is not yet propagated down to ADF BC model - we would need to pass it as parameter to custom method. What if want to have new value to be available in ADF BC model (more...)

Spring Boot / Feign Client accessing external service

Previously we used Feign to create clients for our own services, which are registered on our Eureka Server using a service name as shown in the previous blog post http://theblasfrompas.blogspot.com.au/2016/11/declarative-rest-client-feign-with_8.html. It's not unusual that you'd want to implement an external rest endpoint, basically an endpoint that's not discoverable by Eureka. In that case, you can use the url property on the @FeignClient annotation,
which gracefully supports property injection. His an example (more...)
