Troubleshooting 19c ORA-1: unique constraint (sys.i_indpart_bopart$) during ALTER TABLE SPLIT PARTITION
开始了19c的躺雷模式， 再次建议选择ORACLE 19C版本时安装19.11 以上RU。 最近一客户升级了19C, 本月拆分区时遇到了ora-1 内部字典表数据唯一性冲突， 下面简单记录，报错信息如下:
ALTER TABLE ANBOB.TLOG SPLIT PARTITION PART_110_MAX AT (110, TO_DATE(' 2022-02-01 00:00:00', 'SYYYY-MM-DD HH24:MI:SS')) INTO (PARTITION PART_110_202201 ,PARTITION PART_310_MAX )
ERROR at line 1:
ORA-00604: error occurred at recursive SQL level 1
ORA-00001: unique constraint (SYS.I_INDPART_BOPART$) violated
分析递归SQL,当然做个10046 event trace 就可以，从报错的索引也能知道对象。 下面先看10046 trace

Note:
可见是在update indpart$表，把part#更新为220， obj#能确认业务索引对象， 违反了indpart$的唯一约束。

NOTE:
内部在更新 indpart$时，因为违反了bo#, part#唯一性冲突。索引基于的对象bo#是不变的，拆分区增加的就是part#. 查询indpart$表，确实记录已存在。 正常情况下基于某个段分区local索引和段分区顺序相同的part#也相同，如表分区part# 对应的分区索引part#是相等的。 这里是因为local索引更新出现了不一致。
下面手动创建个表并还原一下问题。

note：
这里用到了2个内部视图tabpartv$ 和indpartv$，也是基于tabpart$和indpart$， 列出了问题part#是从拆的分区开始到倒数第二个分区(最大分区除外).
这里能想到的有3种解决方法：
1， 把索引删除，重新创建(not rebuild)
但是有特殊情况，对于本次出问题的是个lob index（SYS_ILxxxxx）, 不可以删除index。并且move lob级联rebuild lob index也无法解决。
2， 安装one-off patch
Bug 32259535 ORA-1/ORA-00001: unique constraint (sys.i_indpart_bopart$) during ALTER TABLE SPLIT PARTITION, 影响范围RU<=19.10.
3, 更新字典基表
下面用使用最快的第3种方法
