impdp fail with ORA-31623

FYI：

Data Pump import and export job use queues, streams and java objects.

If we see any job component is invalid (e.g. dbms_java, queue dictionary scripts not run, rdbms/admin/utlrp.sql not run) we may see the ORA-31623  error.

The ORA-31623 can also happens if you are not current with patches (running catupgrd.sql and/or catpatch.sql ), see MOSC for details.

To troubleshoot the ORA-31623 error, look for entries in dba_registry where “status=”invalid” and check dba_objects for object that are granted owned by SYS that are invalid.

解决思路：

1.查看alert。log，还需要具体分析日志。

2. 流池可能没有分配内存

select  * from v$sgainfo;  确认 streams_pool_size 是否为零

alter system set streams_pool_size = 10M scope=spfile;    注意该密令要生效需从启数据库

确认是否有组件失效？：

SELECT comp_name, status, version FROM  dba_registry;

3. Oracle bug 。
