alert log中出现了大量的”WARNING: too many parse errors”硬解析错误

近期发现日志文件中多次出现硬解析错误，不知道如何定位和拆除此警示信息。

此问题是由于应用补丁28390461的时候未执行Prvtsqli.plb脚本，建议根据MOS文档Encountering Error 'WARNING: too many parse errors' After Applying WINDOWS DB BUNDLE PATCH 12.2.0.1.181016WINDBBP (文档 ID 2466404.1)的建议重新在数据库端执行以下脚本

Re-load the script in the database by running:

sqlplus ‘/ as sysdba’
