Oracle Reports 12c and DESTYPE=blobdestination

Last week a colleague of mine contacted me to support him for a problem to configure and use Oracle Reports 12c (12.2.1.2.0 and 12.2.1.3.0) with DESTYPE=blobdestination, which means instead of displaying a rendered Report like PDF or XLS or HTML in the Browser to store the generated Report in a LOB into an underlying table in an Oracle Database.

At first you will need to download the (more...)

UKOUG Applications Conference 2018


We need your input!




The Oracle Applications world as many different answers as there are user organisations. So what content do we need to include in our UKOUG_APPS 2018 Agenda?


When I first got involved with UKOUG, we simply has E Business Suite, sliced by the different modules. Today we still have EBS, but we also have those looking at Cloud, and those who have already moved. 


The apps tech community is busy supporting (more...)

Docker: Lessons learned – Logging

After some time working with docker here my experiences:

Some days ago i created my own container with a minimal web service.

Here the ncweb.sh:
#!/bin/ash
sed -i  's/Hostname:.*/Hostname: '$HOSTNAME'/g' index.html
while true; do { echo -e 'HTTP/1.1 200 OK\r\n'; cat index.html;}  | nc  -l -p 8080  2>&1 >> logfile; done
This is the Dockerfile:
FROM alpine

WORKDIR /tmp

RUN mkdir ncweb

ADD .  /tmp

ENTRYPOINT [ "/tmp/ncweb.sh" (more...)

R13 – Get Username Displayed Again

One of the things that we lost when we moved from R12 to R13 is the username in the top right corner. For end-users in production it doesn’t really matter as they’ll only be logging in as themselves, however during the implementation in Test we frequently log-in as different personas so it’s useful to see who the user is for your current session.

The initials we have in R13 offer a clue, but in non-Production (more...)

Documenting APIs on the Oracle API Platform

The last week or two I have been working on a new API Platform utility to add to my existing tools (see here). This tool addresses the question of generating documentation.  Much as been said about API documentation and the quality of it, check out these articles :

If you look at these articles and others, there are some common themes, which are:

  • Document the URI / payload
  • Describe (more...)

Thinking About Oracle Cloud Applications Support


Last week Oracle announced a revision to their Cloud Applications Support . At first glance it looks great, anything that gives the customer more is welcome.

I haven't seen a lot of commentary on this but I like this from Denis Beagle from my friends at Diginomica oracle-announces-autonomous-services-media-day, he talks about it being paid for from the actual subscription costs. I totally agree with that statement but actually think Oracle is moving some of the (more...)

VBCS Goes Technical – but i still love it


Last weekend VBCS was upgraded and in this new version (18.2.3) it is so much more technical to look at.

I first saw this release at the PaaS Forum in March and was deflated, I loved that the product was so easy to use and felt that it did have a market in the system support teams as EBS customers moved to Cloud Applications.

The Product Management team were very helpful, at the PaaS (more...)

Tracking applied Patches in WebLogic Server outfile

With a small trick you can track your applied patches in your Oracle Software Home on your Oracle WebLogic Server in the outfile.

Simply add -Dweblogic.log.DisplayPatchInfo=true to your already existing setUserOverrides.sh or create a new setUserOverrides.sh in your $DOMAIN_HOME/bin directory.

 # Display applied patches in WebLogic Server outfile
JAVA_OPTIONS="$JAVA_OPTIONS -Dweblogic.log.DisplayPatchInfo=true "

After that just restart your WebLogic Server and you will find in the outfile of your WebLogic Server following (more...)

UKOUG Tech 18 Conference

The call for papers for the U.K. Oracle User Group’s 2018 Conference in December is out. The committee are looking for papers across not just core Oracle technologies like the database and SOA Suite but newer technologies such as Event Hub. With Oracle’s engagement with developers and the commitment to open source the UKOUG has moved to engage with these users as well. So the committee will welcome submissions about open source tech that (more...)

Lessons in Oracle Cloud Password Management

Oracle Cloud is growing and maturing at a tremendous rate if the breadth of PaaS capabilities is any indication.  However, there are a few gotchas out there, that can cause some headaches if they get you. These typically relate to processes that impact across different functional areas. A common middleware stack (API CS, SOA CS, OIC etc) will look something like the following:

As the diagram shows when you build the cloud services, the (more...)

Oracle SOA Suite 12c: Invoking a BPEL process via Jdeveloper

After you deployed a BPEL process to your application server open the application server view in Jdeveloper:
 Open the BPEL inside the Application Server view:
 Do a right click on the BPEL process and select "Test Web Service":
 This will open the HTTP Analyzer:
 Fill in your XML input and click "Send Request". After that you will see:


Very nice are the options via the tab at the bottom:

Yesterday redhat announced a new framework to build applications with kubernetes:
The concept of operator framework was build in 2016 from coreos.
CoreOS released the same announcement as redhat. Not really amazing, because:

Here some text snippets from the announcement:
The Operator Framework includes:
  • Operator SDK: Enables developers to build Operators based on their expertise without requiring knowledge of Kubernetes API complexities.
  • Operator Lifecycle Management: Oversees installation, updates, and management of the lifecycle (more...)
