Now that you’ve seen how easy it is to Update WebLogic by rolling out a new patched OracleHome to your managed servers, let’s go one step further and see how we can automate the preparation and distribution parts of that operation as well. ZDT Patching has integrated with a great new tool in 12.2.1 called OPatchAuto. OPatchAuto is a single interface that allows you to apply patches to an OracleHome, distribute thepatched OracleHome to all the nodes you want to update, and...

Now it’s time for the really good stuff!  In this post, you will see how Zero Downtime (ZDT) Patching can be used to rollout a patched WebLogic OracleHome directory to all your managed servers (and optionally to your AdminServer) without incurring any downtime or loss of session data for your end-users. This rollout, like the others, is based on the controlled rolling shutdown of nodes, and using Oracle Traffic Director (OTD) load balancer to route userrequests around the...

Prior to ZDT Patching, there was no easy way to migrate all of your managed servers to a new Java version, but ZDT Patching makes this a simple two step procedure. The first step is to install the updated Java version to all of the nodesthat you will be updating. This...

To get started understanding ZDT Patching, let’s take a look at it in its simplest form, the rolling restart.  In many ways, this simple use case is the foundation for all of the other types of rollouts – Java Version, Oracle Patches, and Application Updates. Executing the rolling restart requires the coordinated and controlled shutdown of all of the managed servers in a domain or cluster while ensuring that service to the end-user is not interrupted, andnone of their session...

Patching and Updating WebLogic servers just got a whole lot easier!  The release of Zero Downtime Patching marks a huge step forward in Oracle's commitment both to simplifying the maintenance of WebLogic servers, and to our ability to provide continuous availability. Zero Downtime Patching allows you to rollout distributed patches to multiple clusters or to your entire domain with a single command. All without causing any service outages orloss of session data for the...
