问题表现

OB 升级到4.2.1版本，部分分区表执行ddl报错-4109错误码， 并报错错误信息：Server state or role not the same as expected。

案例

给表添加字段报SQL 错误 [4109] [HY000]: Server state or role not the same as expected

OCP内部表ob_hist_trans_stat创建分区失败

排查链路

  1. obdiag gather log 收集了一下日志
  2. 通过收集的日志查看rootservice.log，找到了4109的日志，比如发现有如下日志：
__all_table_history’s row not match with __all_table’s(ret=-4109, ret=“OB_STATE_NOT_MATCH”, tenant_id=1002, table_id=501085, schema_version=1708239650768592)

上面的日志表明 __all_table_history和 __all_table 中在tenant_id=1002, table_id=501085这张表中有字段不一致。
3. 通过查询__all_table和__all_table_history表找出在不同的地方

select * from __all_table where tenant_id = xxx and table_id=xxx;

select * from __all_table_history where tenant_id = xxx and table_id=xxx order by gmt_modified desc limit 1;

如第二步中的样例，tenant_id=1002, table_id=501085这张表中有字段不一致，是空字符串和NULL的区别，OB 4.2版本加了__all_table_history和_all_table内容的校验，所以如果插入数据不一致的情况下会报错。重点关注：transition_point, b_transition_point , interval_range , b_interval_range这几个字段。

处理措施

确认__all_table和__all_table_history哪些字段不一致后，手动更新__all_table表中不一致的字段
1、sys租户登陆
2、alter system change tenant tenant_id = xxx; # 切到业务租户（一定一定要现在sys租户登陆再切换）
3、update __all_table set transition_point = NULL, b_transition_point = NULL, interval_range = NULL, b_interval_range = NULL where table_id = xxxx;（更新字段中有不一样的值）

另外可通过一条SQL查询出是否集群存在此问题：
