After more than 11 year from the launch Oracle Exadata Machine has become popular on many companies across industries, making administrators, developers and final users almost unanimously satisfied about performance and availability.

But also, on Exadata there are cumbersome maintenance activities like patching.

Most of my Exadata customers have acquired 2 non-full RACKs, which makes the patching effort quite reasonable; but recently I started working on a project with multiple full RACKs, with tens of Storage Servers, Compute Nodes and hundreds of Virtual Machines…

A very challenging environment, especially when it came to patching…

Patching all the systems using the standard patchmgr utiliy was not acceptable, therefore I had to replace my standard patching procedure with a new one offering automation and scalability.

At this subject Oracle provides few handy options:

Patching Exadata Infrastructure

• Storage Server Patching via http/https server: starting with Oracle Exadata System Software release 18.1.0.0.0, it is possible to patch the Storage Servers using an external http server hosting the new software image. The activitiy can be scheduled up to one week before the installation, allowing on each Cell the Management Server (MS) to start downloading and run pre-checks in advance. MS interrupts the software upgrade and generates an alert if the Cell does not comply with all pre-requisites.

• Unbreakable Linux Network: ULN offers software patches, updates, and fixes for Oracle Linux and Oracle VM. The implementation of a local YUM repository leverages the patch automation of the bare metal OS or dom0/domU.

• InfiniBand Switch: standard rolling upgrade patching procedure using patchmgr.

Patching Grid Infrastructure & RDBMS

• GI & RDBMS: those components are patched using the standard Oracle tools common to all platforms, but the entire process has been parallalized using OS tools like dcli commands.
