Software Upgrade Requirements

Language:

This section describes the requirements that apply when you upgrade a software component to a new major revision. For example, when you upgrade the Grid Infrastructure from 12c to 18c. These requirements do not apply to PSUs or Proactive patches.

Only these software components can be upgraded to a major revision:

MiniCluster Configuration Utility
Storage tray firmware
Compute node firmware
Grid infrastructure (see Note)
Shared file system (see Note)

Note - When upgrading the grid infrastructure or shared storage, the current release must be updated to the latest proactive patch level before the upgrade. For example, a system running Oracle Database 12.1 with the April 2018 Proactive patch must be updated with the October 2018 Proactive patch (assuming that is the latest available) before the system can be upgraded to Oracle Database 18c. Also, the system must be idle with no database or applications running.

Requirements When Updating to MiniCluster 1.3.0 (or later)

MiniCluster must be at release 1.2.5.22 before upgrading to 1.3.0 (or later).
The compute node OS release must match the release provided in MiniCluster version 1.2.5.22.
The Grid Infrastructure must be at release 18c with the latest patches applied (delivered with MiniCluster 1.2.5.22).
All DB Homes must be patched with the latest patches that are available in the 1.2.5.22 release.
You must upgrade MiniCluster software components in this order:
1. MCMU and Compute Node OS (provided In the MiniCluster Core Software bundle) – upgrades the OS on the global zone, kernel zones, and VMs to Oracle Solaris 11.4.
2. Grid Infrastructure (provided in the MiniCluster Component Bundle) – upgrades the grid infrastructure in the kernel zones to 19c.
3. Oracle DB Homes (provided in the MiniCluster Patch Bundle) – Patches existing DB Homes with patches from the MiniCluster 1.3.0
