Zero Downtime Patching for Fusion Middleware HA Topologies

What is Zero Downtime Patching?

With Zero Downtime Patching (aka ZDT), a patch can be rolled through an Enterprise / High Availability implementation, one component at a time. This ensures that the system can remain available and functioning during the patching process. Many Fusion Middleware products now support this type of patch. However, note the applicable versions below:

  • 11g -  patchset 11.1.1.7 or higher must be in place first
  • 12c - 12.1.2, 12.1.3 or higher

Example

A ZDT patch allows the patched and non-patched components of the system to run side-by-side to provide continuous service.

In the diagram below, a 2-node cluster is running two Managed Servers. The Managed Servers are part of the same Cluster. This means they are running the same applications and any server can fulfill a user request.

Each node or machine also has a separate Oracle Home. In this example, a ZDT patch is applied to one Home at a time.

The starting state:


1. Server on Node1 - server1 - is shutdown
2. Patch is applied to the Oracle Home from which server1 is running
3. Restart server1

At this point, the instance of App A on server1 is patched (running from a patched Oracle Home) but the instance on Node2 - server2 - server2 is not patched.

For a ZDT patch (and a ZDT patch only) this state is acceptable during the patch window.

Finally, the patch is rolled through the rest of the system:

1. Server on Node2 - server2 - is shutdown
2. Patch is applied to the Oracle Home from which server2 is running
3. Restart server2

The patch has now been applied to the entire system. At no point was the entire system down.

How to identify a ZDT patch?

A Zero Downtime Patch is identifiable by the instructions in the patch's README file.

The README should say, for example:

This patch has been marked as eligible for Zero Downtime Patching. The type of Zero Downtime Patching supported by this patch is FMW_ROLLING_ORACLE_HOME.

If this phrase does not appear in the patch README then this is not a Zero Downtime Patch and should be applied as normal. following the instructions in the Patch README.

More Information

This blog entry is intended to give a heads up to "zero downtime patching." If you are interested in finding more it is important to read support document:

Zero Downtime Patching in Fusion Middleware (Doc ID 1942159.1)

which provides detail about:

  • ZDT patching prerequisites and limitations
  • In-place and Out-Of-Place patching
  • Other uptime options which you may see in a patch readme

Beware of non-Oracle sites Offering Patches

It has come to our attention that there are non-Oracle web sites which appear to offer Oracle software patches / fixes for genuine Oracle error messages and/or known issues.

Be careful if you decide to engage such sites. In particular, avoid clicking on download links which they may feature unless you are absolutely sure the link will take you directly to an official Oracle web page.
  1. Oracle "patch / fixes" downloaded from non-Oracle web pages are NOT authorized by Oracle.
  2. Non-Oracle sites, offering such "patches / fixes", may expose your system to malware or viruses.
If you do encounter one of these sites please inform us immediately via Communities or create a SR. Oracle Support will seek to rectify the situation as quickly as possible.

Unsure if an Oracle patch can be trusted? Contact :

Patch Reviews - Middleware (My Oracle Support Community)

Additional Notice:

Oracle product documentation and all support documents published in My Oracle Support are copyrighted by Oracle. Furthermore, such documents are subject to continuous improvement / revision. Do not re-post / publish Oracle documentation and technical support documents on non-Oracle sites.  If you wish to share knowledge of a useful document, pass on a description or review along with a link to the document's location.

Fusion Middleware Error Correction Policy - Have You Got a Patch and Maintain Strategy?

It is not uncommon to come across Fusion Middleware 11g product solutions which do not have the latest patch set applied. Example: a business has a SOA Suite 11.1.1.3 in production. The solution has been working fine for three years, and then new business requirements forces an application change. The change, unfortunately, breaks rather than enhances existing functionality. A Service Request is logged with My Oracle Support and the business receive the news that the problem is caused by a bug, a patch for which is available. "Good news!" But, it is a patch which can only be applied against the latest patch set. Furthermore, the fix will not be backported to 11.1.1.3. "Oh .. really .. why can't we get a fix for the patch set we are on? Lifetime Support Policy - Level: Premier Support - has not yet expired for 11g."

The business has been blissfully unaware of the Server Technology Products Software Error Correction Policy.  This document describes the different types of patches which Oracle may release for products and the policies which surround them. It is particularly important, however, to read the product line specific advice found in the Appendix. To part quote, the advice for Oracle Fusion Middleware:

Grace Period: up to 1 year, minimum 3 months.

You have up to one year from the initial release of the patch set to install the new patch set, and can receive new bug fixes for the previous patch set during that time ...

For details (including links to documents containing error correction dates for specific products and patch sets), see

Error Correction Support Dates for Oracle Fusion Middleware (10g/11g/WLS) (Doc ID 944866.1).

In 944866.1, you will find a link to

Error Correction Support Dates for Oracle Fusion Middleware 11g (11.1.1/11.1.2) (Doc ID 1290894.1)

which shows that the error correction grace period for Fusion Middleware (which covers SOA) 11.1.1.3 ended in January 2012. This explains why, in our scenario above, the business will need to first apply the latest available patch set, followed by the interim patch in order to fix their issue.

In conclusion, having a patch and maintain strategy is essential. Maintaining Fusion Middleware products at the latest major version and/or patch set release + updates has the following benefits:

  • Proactively applying the latest patch set and updates can avoid problems and therefore minimize downtime.
  • It can reduce the time taken to consume or obtain fixes for new issues.

If you are using Oracle Fusion Middleware 11g, bookmark and regularly review:

Information Center: Patching and Maintaining Oracle Fusion Middleware 11g (Doc ID 1341616.2)

Screenshot of Information Center: Patching and Maintain Fusion Middleware 11g

This Information Center contains links to knowledge articles which discuss the Error Correction policy and list Error Correction end dates. The Information Center is also a one stop shop for links to patch and patch set collateral:

  • Patch Set Release Announcements
  • Patch Set Updates (including Critical Patch Update) information
  • Patching Documentation 
  • And more ..

Get proactive, know your error correction end dates and put in a place a strategy to keep your product up to date with the latest patch set and updates.

Oracle Database 11.2 April 2012 CPU Includes OC4J 10.1.3.4 Patch

We received an email today from one of the Oracle Application Server Install and Admin Support Delivery Managers bringing to light that a number of Service Requests are being raised by DBAs questioning whether the Oracle Database 11.2 April CPU genuinely requires an OC4J (Oracle Containers for Java) patch to be applied. To quote from:

Patch Set Update and Critical Patch Update April 2012 Availability [ID 1406574.1]
Table 6 Patch Availability for Oracle Database 11.2.0.3

includes the row:

Product Home Patch Advisory Number Comments
Oracle Database home Patch 13705478 CVE-2011-5035 OC4J 10.1.3.4 one-off patch (Special OPatch needed, see README)

** Be sure to check  ID 1406574.1  for the rest of the table details. Above is just an excerpt!

OC4J is normally a component which administrators associate with Oracle Application Server 10g - it's not a component one normally associates with the Oracle Database.

It is, however, NOT a documentation bug. The April 2012 Critical Patch Update document is accurate.  There is a 10.1.3.4 OC4J directory found in the 11.2.0.3 Database Home.  This patch covers a public vulnerability - CVE-2011-5035 - within that directory.  In fact, this patch was actually released as part of the January 2012 Security Alert, refer to:

Oracle WebLogic Server and Oracle Application Server (OC4J) Security Alert for CVE-2011-5035 [ID 1400322.1]

DBAs maintaining Oracle Database 11.2 should apply this Patch 13705478 , following the README bundled with it to ensure it is applied without issue.
