Upgrading Oracle Siebel CRM Application Without Downtime

Oracle’s Siebel Customer Relationship Management (CRM) software helps organizations differentiate their businesses to achieve top- and bottom-line growth. Siebel CRM delivers comprehensive solutions that are tailored to more than 20 different industries. As Siebel CRM implementations have evolved into mission critical, operational business processes that must operate 24/7, companies are finding it increasingly difficult to afford the downtime typically required to perform an in-place upgrade. Without these upgrades, businesses loose out on critical new features and functionality.


With Oracle GoldenGate, customers don’t have to choose between upgrades and outages. Oracle GoldenGate allows Siebel CRM customers to perform upgrades with zero downtime. Now Siebel customers can always take advantages of the latest innovations in customer relationship management without having to worry about potential lost revenue due to downtime.


Oracle GoldenGate provides three different deployment models for Siebel CRM zero downtime upgrades that are designed to meet differing customer requirements. These range from a basic unidirectional model, which is designed to work out-of-the-box, to the most sophisticated active-active model for phased migrations.


If you have mission-critical Siebel CRM implementations I recommend that you watch the screencast below to learn how you can begin taking advantage of all the latest Siebel enhancements without having any downtime.

This screencast is also available on Oracle Media Network and Oracle's YouTube channel. For even more details I recommend reading the whitepaper Upgrading Siebel CRM with Zero Downtime .

What Comes Next After You Decide on Using Oracle Exadata

As Oracle Exadata continues to expand its footprint for both transaction and analytical processing, moving existing systems to Exadata and feeding it with enterprise data on an ongoing basis have become important discussion topics for Exadata customers. Consolidation and migration is the first step of this powerful journey with Exadata, and I'd like to start there in today's blog post.   

The systems that benefit from Exadata's extreme performance and reliability are typically business-critical systems that carry major risks when it comes to migration. Any downtime or data loss can have significant impact to the business in terms of revenue generation, customer loyalty, and productivity. As Oracle GoldenGate user community knows well, GoldenGate's heteregenous, real-time, and bidirectional replication capabilities enable very strong zero downtime migration and consolidation solutions for major databases and platforms including Oracle, IBM DB2 (zOS, iSeries, and LUW), HP NonStop, SQL Server, Sybase ASE, MySQL, and Teradata.

We discussed GoldenGate's zero downtime migration to Exadata offering and best practices with our customer IQNavigator in a webcast that is now available on demand:

Zero-Downtime Migration to Oracle Exadata Using Oracle GoldenGate: A Customer Case Study

If you have not watched it, I highly recommend listening to the discussion, as it clearly explains there should be no concerns around causing business interruption when moving to Oracle Exadata using GoldenGate.  GoldenGate's failback option to the old environment is a great tool for minimizing risk and many organizations adopt that approach for their business-critical systems.  

In addition to migration to Oracle Exadata, customers use GoldenGate, and Oracle Data Integrator, with Exadata in a variety ways leveraging the natural fit between these technologies:

  • Active-active database synchronization across the globe for data distribution, continuous availability, and zero downtime maintenance purposes.
  • Real-time or near real-time data loading to data warehouse, or consolidated database, on Oracle Exadata from heterogeneous sources. Oracle Data Integrator plays the major role in this use case as it integrates with GoldenGate and loads data warehouse in near real-time after performing transformations within the Exadata machine. This use case will be another blog topic soon as it is a strong best practice for performing ETL/ E-LT for Exadata.
  • Moving change data from an OLTP application running on Exadata in real time, for downstream consumption by other systems including supporting service integration.

As additional resources on best practices for migrating to Exadata I'd like to point you to couple of great white papers: Zero-Downtime Migration to Oracle Exadata Using Oracle GoldenGate and Oracle GoldenGate on Exadata Database Machine.

Near Zero Downtime Upgrades for Oracle Communications Billing and Revenue Management

Billing application is one of the key systems for a communications company. It is critical for not only revenue generation but also for customer experience.  Oracle Communications Billing and Revenue Management (BRM) solutions offers a flexible and reliable solution that helps service providers maximize customer value and profitability, and enhance business agility. Oracle BRM supports new business models including cloud, machine to machine (M2M), and mobile virtual network operators (MVNO).  Many of the world's leading, and innovative service providers—including France Telecom, Vodafone, Swisscom, Savvis, Sirius XM Satellite Radio and Nintendo, rely on the BRM application for their critical billing operations.

When it comes to upgrading a major system, such as BRM, things may get a bit tricky. Until recently there were only two approaches to upgrading BRM systems: In-place upgrades and the parallel system run. The in-place upgrade approach means the current BRM system would be shut down and brought back up after it is upgraded to the latest release of BRM. In addition to downtime, it puts heavy risk on the business. The parallel system run approach is an attempt in having two BRM systems running live in parallel. Unfortunately, this approach could only keep a portion of the data in-sync between the two systems as not all data feeds could be applied to both databases. Both of these approaches to upgrade resulted in downtime, which is not desirable for a system that drives revenue and impacts customer experience directly. 

Oracle GoldenGate offers a third approach to upgrade BRM systems and fortunately this new solution delivers near zero downtime and minimized risk.  Using GoldenGate's real-time data replication capability IT teams can create a full copy of the new BRM system on the latest software release without impacting the current BRM system. End users can use the old version, while a parallel system can be upgraded to the newest version of the release, kept in synch in real time with the active database, and tested thoroughly without time pressure before end users switch over to the upgraded BRM instance. GoldenGate's failback option also mitigates the risk to the business during the upgrade process. Oracle GoldenGate’s unique software platform does not require any changes to the source BRM system and uses minimal system resources. The solution supports BRM clients running BRM 7.2 or higher.

This is a very powerful solution for BRM users and we decided to explain the solution in depth via a screencast to help BRM users understand the new method better. If you have a mission-critical BRM system I highly recommend watching the screencast below to learn the detailed implementation steps.

You can watch the screencast also on Oracle Media Network, or Oracle's YouTube account. We have a white paper Near Zero Downtime Upgrade for Oracle Communications Billing and Revenue Management (BRM) Application that you can download for more information as well.
