Linux x86-64

Goal

NOTE: This note has become obsolete and is not maintained. 

  • <document 1473002.1> should be followed for updating Exadata DB nodes currently on releases 11.2.2.4.2. or later
  • When running Exadata Images older than 11.2.2.4.2, first update to 11.2.2.4.2 following the README instructions in <patch 13513611>. When required also update the Linux Operating system from 5.3 to 5.5 following <document 1284070.1> 

 

As of Oracle Exadata Storage Server Software 11g Release 2 (11.2) 11.2.3.1.0, the minimal pack has been discontinued. The Linux database server update procedure uses the Unbreakable Linux Network (ULN) for the distribution of the updates. The updates are now packaged as several rpms and the Linux YUM utility is used to apply the updates. This document will describe the following steps in this process:

NOTE: This document should be used for applying Exadata release 11.2.3.2.0 and higher on existing Exadata releases running version 11.2.1.2.0 or higher. Use the command 'imageinfo' to find out what release your database server is running. When patching a node it's highly recommended  to create a backup first using the backup script "dbserver_backup.sh"

How to use this note

Depending on the Exadata Storage Software release currently running on your database nodes, you should review particular sections of this note. Regardless of your current release, you should review sections 1 through 4 and sections 7 through 9 as they will assist in ensuring a successful patching session. 

Regardless of your current release, you must create a local yum repository to contain the Exadata ULN channel contents.  To complete the repository creation process, you will execute the steps in Section 3 "Preparing and Populating the yum Repository Server".  These steps can be done without downtime to the databases and applications on the database nodes and should be done well prior to the actual database node upgrade to reduce impact to application availability.

If your current release is 11.2.2.4.2 or earlier, you must perform an initial setup of the database node to allow for patching with yum and using the Exadata ULN channels.  To perform both the initial setup and the actual upgrade, you will execute the steps in Section 5 "Performing One-Time Setup on Database Servers of Oracle Exadata Database Machine".  Once these steps are completed successfully and all database nodes show the correct release in the imageinfo command, you are done with the patching session.

If your current release is 11.2.3.1.0 or later, the database node will already be configured to patch using yum and the Exadata ULN channels.  To perform the upgrade, you will execute the steps in Section 6 "Updating Database Nodes previously patched or freshly imaged to 11.2.3.X.X".  Once these steps are completed successfully and all database nodes show the correct release in the imageinfo command, you are done with the patching session.
