本文主要是介绍Oracle RU 19.21及 datapatch -sanity_checks，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！
参考文档：
Oracle® Database Patch 35643107 - Database Release Update 19.21.0.0.231017
| Datapatch User Guide (Doc ID 2680521.1) |
datapatch fails with ORA-04061/ORA-4065/ORA-04045/ORA-04067 due to Golden Gate triggers. (Doc ID 2301658.1)
在19.21的RU的readme中，3.3.2 Load Modified SQL Files into the Database中多了一个可选的步骤。% ./datapatch -sanity_checks (optional)。
read me中是这么说的
Recommended: The datapatch -sanity_checks optional step runs a series of environment and database checks to validate if conditions are optimal for patching. Results are shown on screen with severity and potential actions to take. For more information, refer to the My Oracle Support document 2680521.1 Datapatch User Guide for additional information and actions. Oracle highly recommends that you perform this step.
在安装过程中，测试了一下这个命令，过程如下：
[oracle@19ctest OPatch]$ ./datapatch -sanity_checks
