异常

正常情况下，数据泵导入是可以跨版本的，但是此处却出现了异常

分析

19.17 的时区版本是 32，19.18 的时区版本是 40，所以此处应该升级

解决

升级 PSU

升级此处就不做赘述了，就写一下大体步骤

1. 升级 OPatch
2. 升级 PSU 至 19.18 版本

升级时区版本

1. 检查时区版本

   SQL> select * from v$timezone_file;
   
   FILENAME		VERSION     CON_ID
   -------------------- ---------- ----------
   timezlrg_32.dat 	     32 	 0
   复制

2. 运行升级 check 脚本

   SQL> @?/rdbms/admin/utltz_upg_check.sql
   
   Session altered.
   
   INFO: Starting with RDBMS DST update preparation.
   INFO: NO actual RDBMS DST update will be done by this script.

   INFO: Note that the utltz_upg_apply.sql script will
   INFO: restart the database 2 times WITHOUT any confirmation or prompt.
   
   Session altered.
   复制

3. 执行时区的升级
   注意：此处会对数据库做重启操作，生产数据库需要根据情况而选择时段进行升级

   SQL> @?/rdbms/admin/utltz_upg_apply.sql
   
   Session altered.

4. 验证升级结果

   SQL> select * from v$timezone_file;
   
   FILENAME		VERSION     CON_ID
   -------------------- ---------- ----------
   timezlrg_40.dat 	     40 	 0
   复制

此时已经解决，再导入数据进行验证，已无报错，成功导入
