最近有个datapump跨数据库迁移数据时，提示”ORA-39002: invalid operation”错误， 排除过目录文件权限和语法兼容问题，后来发现是目标库的Timezone Version低于源库的TZ version. 需要升级目标库的TZ VERSION，这里简单记录该问题.

$ impdp xxx@xxx directory=xxx  dumpfile=xxx.dmp logfile=xxx.log table_exists_action=replace

官方文档Oracle Database Globalization Support Guide 对应的版本, 4.7 Upgrading the Time Zone File and Timestamp with Time Zone Data 章节有记录如何升级，可以使用utltz_* Scripts或DBMS_DST Package 完成升级。

Note:
注意CDB是31，但是PDB 还是18，之前的升级并不完整。

解决方法
升级低版本的Timezone version

SQL> shutdown immediate
SQL> startup upgrade
SQL> exec dbms_dst.begin_upgrade(31)
SQL> shutdown immediate
SQL> startup

— for pdb

Updating the RDBMS DST version of the CDB will not change the RDBMS_DST version of the PDB’s in this CDB.
Updating the RDBMS DST version of a PDB will not change the RDBMS_DST version of the other PDB’s or the CDB.
When creating a new PDB the RDBMS DST version of new PDB is the RDBMS DST version of PDB$SEED.
The RDBMS DST version of PDB$SEED is the RDBMS_DST version at the CDB creation time (default is DSTv18 for 12.1.0.2 and 12.1.0.1).
The RDBMS DST version of PDB$SEED can currently not be updated.

From 12cR2 onwards, timezone upgrade scripts are included in the target ORACLE_HOME under rdbms/admin directory.

Then set the below to login to PDB.

Perform the Prepare Window and Upgrade Window in PDB.

Prepare Window

$ cd $ORACLE_HOME/rdbms/admin

SQL> Show con_name

SQL> show con_id

SQL>
SQL> @utltz_countstats.sql
SQL> @utltz_countstar.sql
exec dbms_scheduler.purge_log;
select count(*) from SYS.WRI$_OPTSTAT_HISTGRM_HISTORY;
select count(*) from SYS.WRI$_OPTSTAT_HISTHEAD_HISTORY;

-- check the data retention period of the stats
-- the default value is 31
select systimestamp - dbms_stats.get_stats_history_availability from dual;

-- disable stats retention
exec dbms_stats.alter_stats_history_retention(0);

-- remove all the stats
exec DBMS_STATS.PURGE_STATS(systimestamp);

-- check the result of the purge operation
select count(*) from SYS.WRI$_OPTSTAT_HISTGRM_HISTORY;
select count(*) from SYS.WRI$_OPTSTAT_HISTHEAD_HISTORY;

exec dbms_stats.alter_stats_history_retention(31);

Upgrade Window

Run the utltz_upg_check.sql script from the $ORACLE_HOME directory:
spool utltz_upg_check.log 
@utltz_upg_check.sql 
spool off

Run the utltz_upg_apply.sql script from the $ORACLE_HOME directory after the utltz_upg_check.sql script is executed successfully: This script utltz_upg_apply.sql will shutdown and bring up the database two times.

spool utltz_upg_apply.log
 @utltz_upg_apply.sql 
spool off
