On May 21st, 22nd and 23rd – AMIS and Oracle join forces for a three day event around enterprise application development with Oracle Fusion Middleware. The event targets senior (ADF) developers and application architects. It addresses many of the themes currently or shortly relevant to any organization: multi device UI, mobility, security, agile & automated software engineering, performance & scalability, user experience, web & mobile oriented architecture and cloud. It will discuss and demonstrate Oracle’s (more...)
The Heartbleed bug has shown that security vulnerabilities can pop up everywhere. Unfortunately, many IT organizations depend on a single security layer to secure their network – and as the ineffectiveness of the Maginot Line proved, that is a risky strategy. You need multiple security layers – what soldiers call Defence in Depth.This illustration is from my weekly Technology That Fits newsletter – sign up here.
I'm currently at IOUG Collaborate 2014 in Las Vegas, and I recently finished my 2-hour deep dive into WebCenter. I collected a bunch of tips & tricks in 5 different areas: metadata, contribution, consumption, security, and integrations:
As usual, a lot of good presentations this year, but the Collaborate Mobile App makes it a bit tough to find them...

I have been blogging about the integration between Oracle eBS and Oracle BI EE. Apart from the integration, there are are few assumptions: Oracle eBS is installed Oracle BI is installed Oracle eBS and Oracle BI are compatible with each other (http vs. https) All necessary Oracle eBS patches are installed R11 check R12 included […]
One thing that bugs me is browser security. When I access Oracle Enterprise Manager 12c (OEM12c) through a browser and get the certificate error (Image 1), it just pushes my buttons. Why not ship a valid certificate with OEM12c? In reality, the problem is not with OEM12c; it is actually with the browser you choose to use. In my case, I use Google Chrome a lot with OEM12c. So how (more...)
A bit of a follow-up to my previous post on Digest authentication.
The fun thing about doing the hard yards to code up the algorithm is that you get a deeper level of understanding about what's going on. Take these lines:
v_in_str := utl_raw.cast_to_raw(i_username||':'||i_realm||':'||i_password);
v_ha1 := lower(DBMS_OBFUSCATION_TOOLKIT.md5(input => v_in_raw));
Every time we build the "who we are" component for this site, we start with exactly the same (more...)
I will describe how you configure trust stores for the WebLogic Server.
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...)
When implementing BPM processes, for each deployed BPM process an application role is created in the policy store. To enable users to work with the processes, groups are assigned to these application roles. Users are ofcourse assigned to their respective groups. Management of the BPM process application roles is available in Enterpsie Manager Fusion Middleware Control or the BPM workspace.
Let’s first use Fusion Middleware Control. We need to go to the security section.
When I was patching all of our agents on our linux nodes with the latest PSU (22.214.171.124.5), I encountered an error with one linux node.
PREREQ_NAME: Performer check
PREREQ_DESC: Check if current performer are the file owner of /apps/oracle/product/agent12c/core/126.96.36.199.0.
PREREQ_MESG: Current user tony from Normal Oracle Home Credentials is not the file owner of /apps/oracle/product/agent12c/core/188.8.131.52.0.

In every business, there is a balance between business goals and various impediments.
You need to make sure that you don’t allow legal, QA, security and other internally-focused concerns tip the scale towards paralysis. There is more in this week’s edition of my newsletter “Technology That Fits” – sign up here.
Suddenly, our offshore colleagues could not access the database. We scrambled to find a solution, and and it soon transpired that the central security function had rolled out out a security policy upgrade the night before. Unfortunately, our offshore colleagues were connected to the network in an uncommon way, so the new security policy cut them off.
You don’t know what will happen when you change a system. Enterprise IT landscapes have reached a complexity (more...)
This post is about exploring the mechanisms used by Oracle Clusterware 184.108.40.206 to restrict remote service registration, i.e. the 12c new feature "Restricting Service Registration for Oracle RAC Deployments"Why is this useful?
This improvement of 12c clusterware and listeners over the 11.2 version is useful mainly for security purposes, for example as a measure against TNS poisoning attacks (see also CVE-2012-1675
), and it is particularly relevant for (more...)

I recently got my hands on a review copy of Learning Devise for Rails
and was quite interested to see if it was worth a recommendation (tldr: yes).
A book like this has to be current. Happily this edition covers Rails 4 and Devise 3, and code examples worked fine for me with the latest point releases.
The book is structured primarily as a (more...)
We recently upgraded our EM12c 220.127.116.11 installation to 18.104.22.168. This service was configured to authenticate logins against our Active Directory server via LDAP. However, after upgrading we found that authentication stopped working, even after recreating the Active Directory Authenticator (as required). I could see the list of users from AD, but could not authenticate them in EM!
In this post I'm going to share what we did to diagnose (more...)
There has been a policy in integration that has stored up a really great challenge of data security, and by great I don't mean 'fantastic' I mean 'aw crap'. Its a policy that was done for the best of reasons and one that really will in future represent a growing challenge to Big Data and federated information.
The policy can be described as this:
