错误再现分析

在使用数据泵导数据时，遇到下面错误：

[oracle@gsp db_expd_bak]$ expdp system/xxxx   directory=dump_dir dumpfile=dm.dmp tablespaces=dm content=all;

ORA-00832: no streams pool created and cannot automatically create one

造成ORA-00832：no streams pool created and cannot automatically create one错误的原因一般是streams_pool_size太小或没有定义streams_pool_size

A database feature which needs STREAMS SGA was being used, however, the streams_pool_size parameter was not defined and the value of db_cache_size was too small to permit an automatic transfer of SGA to the streams pool from the buffer cache.

Action: Please set the parameter streams_pool_size or set sga_target

SQL> show parameter streams_pool_size

NAME                                 TYPE        VALUE

------------------------------------ ----------- ------------------------------

streams_pool_size                    big integer 0

SQL>

由于STREAMS_POOL_SIZE一般在ASSM中是动态分配的，所以参数streams_pool_size一直为0，要查看streams_pool_size的真实大小就必须通过下面脚本来查询：

查看streams_pool_size的实际大小，发现其大小为0，更让我吃惊的却在后面：sga_target 为0，也就是说数据库没有启动自动共享内存管理（Automatic Shared Memory Management ASMM）。真是绕了一大圈。所以必须手动调整streams_pool_size的大小：

epps> alter system set streams_pool_size=100M scope=memory;

alter system set streams_pool_size=100M scope=memory

*

ERROR at line 1:

ORA-02097: parameter cannot be modified because specified value is invalid

ORA-04033: Insufficient memory to grow pool

epps> alter system set streams_pool_size=1M scope=memory;

alter system set streams_pool_size=1M scope=memory

*

ERROR at line 1:

ORA-02097: parameter cannot be modified because specified value is invalid

ORA-04033: Insufficient memory to grow pool

因为SGA采用老的分配方式，没有采用ASSM管理SGA，需要从其它内存中释放一些内存出来分配给streams_pool_size，结合分析，最后从

shared_pool_size中分配32M出来给streams_pool_size。问题解决，另外一个解决方法就是讲sga_target设为非零。让SGA动态给streams_pool_size分配内存。
