在Oracle 18c 插入PDB時需要進行相容性檢查，在執行DBMS_PDB.CHECK_PLUG_COMPATIBILITY時會報ORA-07445: exception encountered: core dump [__intel_ssse3_rep_memcpy()+6461]的錯誤，如下：

根據MOS 文件說明，這裡是Oracle 18c 的bug：
DBMS_PDB.CHECK_PLUG_COMPATIBILITY = ORA-3113 / ORA-7445[__intel_ssse3_rep_memcpy()+6429] (文件 ID 2446450.1)
解決方法就是升級到19.1 或者打Patch 28502403 ，我們這裡選擇打補丁：
