Easy upgrade path from CMSDK 9.0.4.2 to 9.0.4.6

Each Oracle CMSDK 9.0.4.6.x release comes with three different installation options.
  1. Create a new Oracle CMSDK 9.0.4.6 schema
  2. Upgrade from an existing Oracle CMSDK 9.0.4.2 installation
  3. Patch an existing 9.0.4.6.x installation

The upgrade process is divided into three phases: the Pre-SchemaUpgrade, Offline-SchemaUpgrade and Post-SchemaUpgrade phases.

Within each of these phases, a list of upgrade actions are performed in a specific sequence. The time required to complete the entire upgrade process depends on the size and complexity of the existing Oracle CMSDK schema. To minimize the down time of a production system, most of the long running actions are executed during either the Pre-SchemaUpgrade or the Post-SchemaUpgrade phase, because during these phases the system can remain in production. It is only during the Offline-SchemaUpgrade phase that the Oracle CMSDK system must be completely shut down.

Here is a brief overview of the three phases.

Pre-SchemaUpgrade

  • Executes while 9.0.4.2 system is running
  • Performs a number of long running actions
  • Can be executed multiple times before beginning next phase
Offline-SchemaUpgrade
  • 9.0.4.2 system must be shut down as this phase begins
  • Optimized to complete in a relatively short period of time
  • Pre-SchemaUpgrade actions are executed again, to process any "deltas" since the last time that phase completed
  • Offline-SchemaUpgrade actions are executed only once
Post-SchemaUpgrade
  • Can execute while 9.0.4.6 system is running
  • Performs actions which are largely optimizations
Our internal tests showed that a CMSDK system with 10 million documents required an actual down time of less than 15 minutes and a total upgrade time of roughly 25 hours. Again, this can vary based on other factors.

Detailed upgrade and installation instructions can be found in the Readme bundled with each release.

Still on CMSDK 9.0.4.2 ?

CMSDK version 9.0.4.2 was released back in January 2005. This and every subsequent 9.0.4.2.x CMSDK version requires Oracle Application Server 10gR2 (10.1.2.0.2) for its run-time environment. This version of Oracle Application Server and the Java version it depends on (JDK 1.4) have already reached its end-of-life on Extended Support. See Oracle Application Server 10g certification information for more information.

So what now?

Let me explain to you how you can move your existing CMSDK environment to the latest Oracle stack.

In March 2012 we released a new version of CMSDK (version 9.0.4.6.3), which corrects two major issues that existed in CMSDK version 9.0.4.2:

  • Removing the dependency on Oracle Application Server 10g.
  • Making CMSDK compatible with the latest Java versions.

Since then, we have released a new CMSDK 9.0.4.6.x patch every four months. The most recent one, version 9.0.4.6.7, has been released to My Oracle Support as Patch 16465003 in July 2013. This patch includes a number of bug fixes that have been found by customers and partners during their testing of the earlier CMSDK 9.0.4.6.x versions. The Readme that is bundled with the patch contains the list of bugs fixed as well as the installation and upgrade instructions and the list of deprecated features.

CMSDK 9.0.4.6 is certified on current middleware products such as Oracle WebLogic Server or Oracle GlassFish Server and is available for download on My Oracle Support.

The following documents contain some further general information about CMSDK 9.0.4.6:

Welcome CMSDK to the blogsphere!

The first entry.

The development of Oracle Content Management SDK (CMSDK) began back in 1998. It was initially sold as a pure SDK product and its potential was quickly recognized both inside and outside the company. Oracle used CMSDK internally as the foundation for several content management products. Today hundreds of customers are using the core CMSDK and its complete development and run-time environment to rapidly build their own enterprise content management applications.

I have been working with CMSDK since 2001, initially as a Consultant in many customer projects, where we leveraged the robust and extensible platform for developing custom content management solutions. Later I joined Oracle Global Sales Support and traveled around the globe to teach internal classes about the latest products in the areas Content and Records Management, Database Security, Auditing and Compliance. In 2007 I joined Oracle Product Development and became responsible for five different content management and archiving products.

I want to share my acquired knowledge and experience from the last decade, in particular about CMSDK, with you in this blog. Feel free to comment on posts or suggest CMSDK topics that you would like to have covered in this blog.
