expdp导出UDE-31623 ORA-31623

问题描述:

ORACLE EXADATA 12.2 4节点 一个简单的expdp导出，在之前是正常的，但是隔了一天后出现问题了，具体报错信息如下：

expdp '"/as sysdba"' DIRECTORY=dir1 DUMPFILE=vat_%U.dmp logfile=vat_20190505.log VERSION= 11.2.0.4.0 SCHEMAS=VAT CLUSTER=NO exclude=STATISTICS parallel=4

UDE-31623: operation generated ORACLE error 31623

ORA-31623: a job is not attached to this session via the specified handle

ORA-06512: at "SYS.DBMS_DATAPUMP", line 3326

ORA-06512: at "SYS.DBMS_DATAPUMP", line 4551

ORA-06512: at line 1

解决办法：

sqlplus "/ as sysdba

SYS@ora122>show parameter streams_pool

SYS@ora122>select * from v$sgainfo; #其实为0

SYS@ora122>alter system set streams_pool=1g sid='ODS3' ;
