Regular readers know that Premier Support for the Oracle 10gR2 Database ends in July 2010, a scant few months from now.  What does that mean for E-Business Suite environments running on this database?

The Oracle E-Business Suite is comprised of products like Financials, Supply Chain, Procurement, and so on.  Support windows for the E-Business Suite and these associated applications products are listed here:

• Oracle Lifetime Support > "Lifetime Support Policy: Oracle Applications" (PDF)
  

The Oracle E-Business Suite can run on a variety of database releases, including 10gR2, 11gR1, and 11gR2.  Support windows for database releases are listed here:

• Oracle Lifetime Support > "Lifetime Support Policy: Oracle Technology Products" (PDF)
  

Looking at those two documents together, you'll see that:

• Premier Support for Oracle E-Business Suite Release 11i ends on November 30, 2010
• Premier Support for Oracle E-Business Suite Release 12 ends on January 31, 2012
• Premier Support for Oracle E-Business Suite Release 12.1 ends on May 31, 2014
  
• Premier Support for Oracle Database 10.2 (a.k.a. 10gR2) ends on July 31, 2010

[Note: These are the Premier Support dates as of today.  If you've arrived at this article in the future via a search engine, you must check the latest dates in the Lifetime Support Policy documents above; these dates are subject to change.]

It's a bit hard to read, thanks to the layout restrictions of this blog, but the following diagram shows the Premier and Extended Support windows for the last four major database releases certified with Apps 11i:

Do the EBS Premier Support dates trump the 10gR2 DB date?

No.  Each of the support policies apply individually to your combined EBS + DB configuration.  The support dates for a given EBS release don't override the Database support policy.
