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：
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
解决过程：
1、刚开始以为是session数满了，因为该机器session数设置很少，很容易满。经过测试不是该问题，而且我后来想了下如果session数满了的话，报错信息应该不是这个。
2、删除该用户下export表，删除了还是不好使
3、网上查资料，说应该授予create any table的权限，授予了还是不好使
4、查看mos，让检查dba_registry和所有无效对象308388.1，检查了都是对的
5、查看stream_pool_size大小，参考文章How to resolve the Data Pump error ORA-31623 (a job is not attached to this session via the specified handle) ? (文档 ID 1907256.1)；其原值是0，也就是如果自动调节，这个没有下限；查看v$sgainfo看到这个stream pool的大小为32MB，db_cache_size有6G，shared_pool_size有3G，总的sga就9.6G左右，所以这个stream_pool被压制得很厉害，给其设置一个下限值，改成128MB时报错，内存没有多的可用于调节这个，说明sga空闲内存不多了，改成64MB成功，单后执行expdp也成功了。
第一次遇到stream_pool_size导致的expdp问题，记录以下备忘。

There are several possible reasons why a Data Pump cannot be started. Each root cause has its own solution.
Solution
- First check the value for the STREAMS_POOL_SIZE in the database:
connect / as sysdba
show parameter streams_pool
select * from v$sgainfo;
If the STREAMS_POOL_SIZE is too small, then a Data Pump job will fail. This can also happen when using Automatic Shared Memory Management (ASMM), or Automatic Memory Management (AMM) and there is not sufficient memory to increase the STREAMS_POOL_SIZE.
Manual settings for the STREAMS_POOL_SIZE of 64M, 128M or even to 256M have proven to be successful.
For details and full resolution, see:
Note 1080775.1 - UDE-31623 Error With DataPump Export
- Check for any possible invalid Data Pump queue objects:
connect / as sysdba
show parameter aq
col owner for a10
col object_name for a30
analyze table kupc$datapump_quetab validate structure cascade;
analyze table kupc$datapump_quetab_1 validate structure cascade;
select object_id, owner, object_name, status from dba_objects
where object_name like 'KUPC$DATAPUMP_QUETAB%';
set lines 100
col status for a9
col object_type for a20;
col owner.object for a50
select status, object_id, object_type, owner||'.'||object_name "OWNER.OBJECT"
from dba_objects
where object_name like '%DATAPUMP_QUETAB%' order by 3,4;
If there are any invalid queue objects, then a Data Pump job will fail. This usually also results in the following error in the alert.log file:
ORA-00600: internal error code, arguments: [kwqbgqc: bad state], [1], [1], [], [], [], [], []
For details and full resolution, see:
Note 754401.1 - Errors ORA-31623 And ORA-600 [kwqbgqc: bad state] During DataPump Export Or Import
- Check for any invalid registry components (CATALOG, CATPROC and JAVAVM), and invalid sys owned objects:
connect / as sysdba
set lines 90
col version for a12
col comp_id for a8
col schema like version
col comp_name format a35
col status for a12
select comp_id,schema,status,version,comp_name from dba_registry order by 1;
set lines 120
col status for a9
col object_type for a20;
col owner.object for a50
select status, object_id, object_type, owner||'.'||object_name "OWNER.OBJECT"
from dba_objects
where status != 'VALID' and owner='SYS' and object_name not like 'BIN$%'
order by 4,2;
If the registry components CATALOG, CATPROC and/or JAVAVM, and/or objects like SYS.KUPW$WORKER or SYS.KUPP$PROC are invalid, then a Data Pump job will likely fail.
To resolve this problem, reload Data Pump in the database:
connect / as sysdba
-- Start spooling to file:
spool catproc.out
set lines 120 numwidth 12 pages 10000 long 2000000000
alter session set NLS_DATE_FORMAT='YYYY-MM-DD HH24:MI:SS';
show user
select sysdate from dual;
shutdown immediate
-- for 9.2, use: startup migrate
startup migrate
@?/rdbms/admin/catalog.sql
@?/rdbms/admin/catproc.sql
@?/rdbms/admin/utlrp.sql
spool off
spool registry.out
-- Registry status:
set lines 90
col version for a12
col comp_id for a8
col schema like version
col comp_name format a35
col status for a12
select comp_id,schema,status,version,comp_name from dba_registry order by 1;
-- Invalid objects:
set lines 120
col status for a9
col object_type for a20;
col owner.object for a50
select status, object_id, object_type, owner||'.'||object_name "OWNER.OBJECT"
from dba_objects
where status != 'VALID' and owner='SYS' and object_name not like 'BIN$%'
order by 4,2;
shutdown immediate
startup
spool off

Note 1612279.1 - How to Reload the JVM in 12.1.0.x
and/or create a Java SR if more help is needed.
- Check if parameter _FIX_CONTROL is set for Bug 6167716:
connect / as sysdba
show parameter _fix_control
If this hidden parameter is set, then a Data Pump job will fail.
For details and full resolution, see:
Note 1150733.1 - DataPump Export (EXPDP) Fails With Errors ORA-31623 ORA-6512 If Parameter _FIX_CONTROL='6167716:OFF' Has Been Set
- If the Data Pump job is started through a package, check if the package was created with invoker's right (AUTHID clause):
connect / as sysdba
set lines 120 numwidth 12 pages 10000 long 2000000000
col ddl for a100
select dbms_metadata.get_ddl('PACKAGE','MY_PACKAGE','SCOTT') "DDL" from dual;
If the package was created with an invoker's right, then a Data Pump job will fail when started through this package.

- If the Data Pump job is started in DBConsole / OEM, and the job is selected to be re-run (or you want to edit the job), then the Data Pump job will fail and following errors will be reported:
