Overview

Beginning in July 2017,Oracle has transitioned to a more flexible and responsive strategy for the database software release process.? These changes only affect Database and Grid Infrastructure release 12.2 or later.? The primary goals of this strategy are twofold:

1. Embrace a less complex software release process

a. Oracle wants to get new features to market every year instead of waiting several years
b. Oracle desires to improve database release quality by reducing the number of software changes released at one time

2. Provide customers with a more flexible way to both:

a. Efficiently adopt Bug fixes when needed and decrease the need for interim one-offs (like the DB Proactive BP provides for 12.1.0.2)
b. Efficiently keep current with Quarterly Security Updates once their environment becomes stable (like the PSU provides for 11.2.0.4 and 12.1.0.2)

?注：从2017年7月开始，Oracle已经过渡到一种更灵活、更快速响应的数据库软件发布过程。

To accomplish the goals of this strategy,the following database software changes are being implemented:

Database version 12.1 and 11.2 will continue to use the legacy PSU/BP process and version numbering systems. 注：数据库版本12.1和11.2将继续使用以往的PSU/BP流程和版本编号系统。 ? ?

Patching Changes - Release Updates and Release Update Revisions

Beginning with the next Database release (originally designated 12.2.0.2) planned for 2018,new feature releases of the database product are being provided annually,and patchsets are no longer being released.?

To support both security-related fixes and high-priority non-security fixes to each feature release,quarterly Release Updates (Updates) are being provided each January,April,July and October. Oracle‘s quarterly Updates contain fixes for the bugs that customers are most likely to encounter:

Query optimizer bug fixes,which were not allowed in PSU‘s and BP‘s from earlier releases are included disabled by default in the Updates.
Updates include fixes for security vulnerabilities.
Updates go through extensive testing at Oracle,covering functional,stress,performance,and destructive testing scenarios.
Applying Updates in a timely manner reduces the likelihood of rediscovery of known issues.
Updates can be installed with zero down time via RAC rolling.

? 注： 1. 从2018年的下一个版本（12.2.0.2）将提供新特性版本的产品，PSU将不再发布。 2. 新产品的补丁更新同样为季度发布。 3. 新产品的补丁可以在RAC中进行滚动升级安装，不用停机。 ? The Update and Revision strategy replaces the legacy Patchset Update (PSU) and the legacy Database Bundle Patch (DBBP) for 12.2.0.1 database software and subsequent feature releases. As of July,2017,the legacy terms ‘Patchset‘,‘Patchset Update‘,and "Database Bundle Patch‘ are not used for 12.2.0.2 database software and subsequent feature releases. Note that for Database versions 12.1 and 11.2 Oracle continues to release quarterly PSUs and BPs. ? 注：Update and Revision 策略将替换PSU/DBBP，12.1与11.2继续会发布PSU和BP更新。 ? ?

Release Update Revision - Database <Quarter> Release Update Revision 12.2.0.1.<build-date>

Release Version Numbering Changes

Beginning in 2018,a new numbering schema for the database software is implemented. Instead of a legacy nomenclature such as 12.2.0.2,a three (3) field format consisting of: Year.Update.Revision is used,such as 18.1.0. This allows clear indication of:

the feature release designation of the database software (the first field)
the quarterly Update (the second field)
the quarterly Revision (the third field)

注：命名的改变，将采用3位数字表示，第1位表示特性产品版本，第2位表示季度更新版本，第3位表示季度修正版本。 ? ? ?
