Another DOAG is over and here are my summary.

Day 1

As my presentation is planned for noon I arrived this year on the evening before, so I could attend the early sessions on 8:30.

Sten Vesterli: APEX, ADF, or ABCS? A real-life application built in 3 tools

He compares the development of a real application in APEX, ADF and ABCS. He don’t believe that ABCS is usable from end users and shows interesting (more...)

Implementing Authentication for REST API calls from JET Applications embedded in ADF or WebCenter Portal using JSON Web Token (JWT)

imageThe situation discussed in this article is as follows: a rich client web application (JavaScript based, could be created with Oracle JET or based on Angular/Vue/React/Ember/…) is embedded in an ADF or WebCenter Portal application. Users are authenticated in that application through a regular login procedure that leverages the OPSS (Oracle Platform Security Service) in WebLogic, authenticating against an LDAP directory or another type of security provider. The embedded rich web application makes calls to (more...)

Quick introduction to Oracle Container Registry–running one of Oracle’s prebaked images

Oracle has been active with Docker for quite some time now. From the first hesitant steps from some enthusiastic employees with Docker build files that helped people to get going with Oracle software in their experimental containers to a GitHub repo with a broad set of extensive Docker build files to create Docker containers with various Oracle product that are supported (https://github.com/oracle/docker-images). And of course the Oracle Container Cloud – launched in (more...)

Essential WebLogic Tuning to Run on Docker and Avoid OOM

Read my previous post about how to run ADF on Docker - Oracle ADF on Docker Container. Docker WebLogic image is based on official Oracle Docker image for FMW infrastructure - OracleFMWInfrastructure. WebLogic container created based on this image runs, but not for long - eventually JVM process eats up all memory and OOM (out of memory) exception is thrown. This is known issue related to JVM running in Docker container - Running a JVM (more...)

Enable WebService test client on SOA/BPM production mode environments

At my current assignment I need to trouble shoot the identity service because of a BPM->OID coupling. I use the support document 1327140.1 for it, that suggest to test http://<soa-server>:<port>/integration/services/IdentityService/identity

Doing so in a production mode soa or bpm environment, you'll soon find out that it uses the WebService test client via uri /ws_utc, and that this does not work. Resulting in http-404 Not found errors.

First I found a blog of Maarten of Amis (more...)

Implementing the KeyStore Service with Fusion MiddleWare 12c

For the passphrases, use the passphrases used earlier.Thinking about TLS (Transport Layer Security, the succesor of Secure Socket Layer, SSL) and WebLogic and Oracle HTTP Server, allways gave me Cold Water Fear. You have to create keystores with keys, wallets, certificate signing requests, import signed and trusted certificate chains. Not to mention the configuration of WebLogic and OHS.

Now, creating keystores with the Java Keytool turns out not that hard. And generating the Certificate (more...)

Provide access to #WebLogic DMS Spy Servlet for readonly users

For security reasons and to prevent the configuration drift it is recommendable to use read only for analyzing problems.

For read only access of configuration and logs WebLogic provides out of the box the group Monitors. Unfortunately you cannot access DMS Spy Servlet with this group, which is useful for analyse runtime values of the server. Only users which belongs to the Administrators group and therefore have full access can access DMS Spy Servlet and (more...)

Possible solution for TLS 1.2 issues between Windows 10 and Oracle EPM Weblogic


We have recently seen some users of both Dodeca and Hyperion products where Windows 10 machines have issues connecting to the Weblogic servers shipped with Oracle EPM due to the absence of the TLS 1.2 protocol.  The underlying issue is that Windows 10 is an evolution of technology whereas Oracle EPM Weblogic, and more specifically the Java version tested and shipped with it, are stuck in the stone age.  Java 1.6 started its (more...)

Weblogic log level mapping

For quite some time now I wondered about the differences in log-levels. For instance, if you configure the log levels in the classes in SB12c or SOA Suite,  You see levels as INCIDENT , ERROR, and TRACE, even with several sub leverls (1, 16, 32). But on the Server Log configuration in Weblogic, you see levels a s ERROR, NOTICE and DEBUG, or TRACE.  And then in Java, JDK logging we even (more...)

OHS URL Rewrite

First half of this year I did two SAML2 implementations on Weblogic. One of those was to implement Single Sign On against ADFS for Apex applications.

In short, we installed an adapted version of ORDS on a Weblogic server and configured SAML2 for Service Provider initiated SSO, as can be read here.

We added an Oracle HTTP Server as reversed proxy to the story. For the other customer I found out how to create a (more...)

Hey JAVA-developer, why don’t you love your database

Why this post?

Partly, this blogpost is a result of a promise to Lukas Eder. Basically my vision adheres quite nicely to the “Thick Database” driven by Bryn Llewellyn and Toon Koppelaars who, understandibly, drive this from an Oracle perspective.
It –more than of course- also nicely fits EnterpriseDB or even vanilla PostgreSQL database landscapes.

There is apparently still so much confusion in the world on the how, why and what of (more...)

Starting and Stopping Domains Using WLST – The Easy Way

Yes - another post 'how to start/stop a domain using WLST' ... But, with this scripts You only have to provide information about the nodemanager and the AdminServer. All other information used to start the domain is collected dynamically during runtime.

The tool will start or stop the nodemanager (domain- or host-based), the AdminServer and each ManagedServer. Before starting or stopping a component a check is done if the operation in question is possible or not. (more...)

Install and configure Oracle HTTP Server Standalone

Last week I had an assignment to install and configure Oracle HTTP Server as a reversed proxy in a DMZ. Many years ago I worked with Apache a little, so I had not have the details at hand.

Although installing and configuring the HTTP Server is not hard, I found that I had to do quite some searching around to get to all the essentials. To help you out, and to have it logged for (more...)

Fix “BEA-000394: Deadlock detected” for Weblogic with ADF Applications 12.2.1.2

If you try the newest version 12.2.1.2 (or maybe earlier versions too) you see, that your managed server does not restart, when

  • you have deployed your ADF application(s)
  • you try to restart the managed server with ADF
  • you use intentionally or not shared libraries in your weblogic-application.xml (see example below)
<?xml version = '1.0' encoding = 'UTF-8'?>
<weblogic-application xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

Découverte : Java Cloud Service Workshop


Test your WebLogic 12.1.3 enviroment with Robot

Robot Framework is a generic test automation framework which has an easy-to-use tabular test data syntax and it utilizes the keyword-driven testing approach. This means we can write our tests in readable and understandable text. If we combine this with the REST Management interface of WebLogic 12.1.3 we are able to test every detail of a WebLogic domain configuration and when we combine this

Create with WLST a SOA Suite, Service Bus 12.1.3 Domain

When you want to create a 12.1.3 SOA Suite, Service Bus Domain, you have to use the WebLogic config.sh utility.  The 12.1.3 config utility is a big improvement when you compare this to WebLogic 11g. With this I can create some complex cluster configuration without any after configuration. But if you want to automate the domain creation and use it in your own (provisioning) tool/script then you

Oracle SOA Suite 12c tips – Tuning the SOA infrastructure thread pool

One of the new capabilities of Oracle SOA Suite 12c is the ability to control the SOA infrastructure thread pools, except the resource pools for EDN and the adapters, with Oracle WebLogic Server work managers. Each partition will has its own work managers defined. This allows you to separate services in partitions and, to some extent, tune them separately based on for example specific SLA requirements.

Well, this blog posting is not about explaining the (more...)

The WebLogic Server and Trust Stores


I will describe how you configure trust stores for the WebLogic Server.

Overview

Chain of trust

When a SSL server certificate is issued by a CA it is signed by a another certificate. Normally this will be an intermediate certificated, that is again signed by the CAs root certificate. So there is a chain of trust between the (more...)
