1 Introduction
This document describes methods and procedures to perform the following upgrades:
- 8.5.X
- 8.6.0.0.0
- 8.6.0.1.0
- 8.6.0.2.0
- 8.6.0.3.0
- 8.6.0.4.0
- 8.6.0.5.0
- 8.6.0.6.0
- 8.6.0.7.0
Where, X indicates a PI cycle and Y indicates patches within the PI cycle.
This document covers the upgrade of cloud deployments and provides instructions to perform any incremental or major cloud software upgrade. The implementation of this procedure assumes that the target DSR software load (ISO file, CD-ROM or other form of media) has already been delivered to the customer’s premises. This includes delivery of the software load to the local workstation being used to perform this upgrade.
Note:
To understand the capacity and performance impact of this software release, refer to DSR Cloud Benchmarking Guide.1.1 What is Not Covered in This Document
The following items are beyond the scope of this document. Refer to the
specified reference for additional information.
- Distribution of DSR software loads. It is recommended to contact My Oracle Support (MOS) for the software loads as described in My Oracle Support.
- Initial installation of DSR software. Refer to DSR Cloud Installation Guide.
- SDS installation. Refer to SDS Cloud Installation Document.

1.4 Terminologies
This section describes terminologies as they are used within this
document.
Table 1-2 Terminologies
| Term | Definition |
|---|---|
| Upgrade | The process of upgrading an application from its current release on a system to a newer release. |
| Major Upgrade | An upgrade from one DSR release to another DSR release. For example: DSR 8.6 to 9.0.x |
| Incremental Upgrade | An upgrade within a given DSR release e.g. 8.6.0.0.0 to 8.6.0.3.0. |
| Release | Release is any particular distribution of software that is different from any other distribution. |
| Source Release | Software release to upgrade from |
| Target Release | Software release to upgrade to |
| Single Server Upgrade | The process of upgrading a DSR server from its current release to a newer release. |
| Backout | The process of converting a single DSR server to a prior version. This could be performed due to failure in Single Server upgrade or the upgrade cannot be accepted for some other reason. Backout is a user-initiated process. |
| Rollback | Automatic recovery procedure that puts a server into its preupgrade status. This procedure occurs automatically during upgrade if there is a failure. |
| Primary NOAM Network Element | The network element that contains the active and standby NOAM servers in a DSR. |
| Signaling Network Element | Any network element that contains DA-MPs (and possibly other C-level servers), thus carrying out Diameter Signaling functions. Each SOAM pair and its associated C-level servers are considered a single signaling network element. And if a signaling network element includes a server that hosts the NOAMs, that signaling network element is also considered to be the primary NOAM network element. |
| Site Physical Location | Where one or more network elements reside. The site is defined by the SOAM. |
| Geographic Site | A Geographic Site is defined as the physical location of a SOAM and its co-located children, as well as its non-preferred spare SOAM(s). In this document, a Geographic Site is designated as GSite. |
| Topological Site | A Topological Site is defined as a SOAM Server Group and all C-level Server Groups that are children of the SOAM. All servers within a server group belong to the server group’s site, regardless of the physical location of the server. Thus, for upgrade, a Topological Site does not correlate to a ‘network element’ or a ‘place’. In this document, a Topological Site is designated as TSite. |
| Health Check | Procedure used to determine the health and status of the DSR’s internal network. This includes status displayed on the DSR GUI and PM&C GUI. This can be observed pre-server upgrade, in-progress server upgrade, and post-server upgrade. |
| Upgrade Ready | State that allows for graceful upgrade of a
server without degradation of service. It is a state that a
server is required to be in before upgrading a server. The state
is defined by the following attributes:
|
| UI | User interface. |
| Platcfg UI | Platform Configuration Utility User Interface, which is a text-based user interface. |
| N+0 | Set up with N active DA-MP(s), but no standby DA-MP. |
| NOAM | Network OAM for DSR |
| SOAM | System OAM for DSR |
| Migration | Changing policy and resources after upgrade (if required). For example, changing from 1+1 (active/standby) policy to N+ 0 (multiple active) policies. |
| Software Centric | The business practice of delivering an Oracle software product, while relying on the customer to procure the requisite hardware components. Oracle provides the hardware specifications, but does not provide the hardware, and is not responsible for hardware installation, configuration, or maintenance. |
| Enablement | The business practice of providing support services (hardware, software, documentation, and so on) that enable a 3rd party entity to install, configure, and maintain Oracle products for Oracle customers. |
