解决UDE-31623错误一例

一套Linux x86-64上的11.2.0.2数据库在使用data pump数据泵expdp工具导出时遭遇了ORA-31623错误,详细日志如下:

shared_memory_address                integer     0

从以上日志可以看到导出进程在为”fixed allocation callback”从streams pool流池中分配内存时遇到了ORA-04031错误,进而导致了UDE-31623错误。为什么expdp要从streams pool中分配内存呢?data pump数据泵在11g中开始Advanced Queue高级队列来控制其job作业的启动、停止和重启了。如果streams pool的当前size为0,那么显然无法分配到任何内存;而当前系统中就只设置了AMM特性的memory_target内存参数,并没有显式地设置streams_pool_size参数,这就导致了问题的发生。
我们可以通过上症状在MOS上搜索可以找到Note”UDE-31623 Error with Data Pump Export”:

Solution

For this Data Pump error, you will need to configure the database with some Streams Pool.

Perform the following query to find out how much STREAMS_POOL_SIZE has been allocated

 select * from v$sgainfo;
 ...
 Streams Pool Size                               0 Yes

Data Pump now uses Advanced Queuing (AQ) internally, so it can handle job stops/starts/re-starts.  
However, AQ using the Streams Pool, where the database currently has the STREAMS_POOL_SIZE set to ZERO.

Manually set the STREAMS_POOL_SIZE, re-start the database and re-attempt the Data Pump Export.

Alternately, turn on Automatic Shared Memory management (ASMM) by setting SGA_TARGET or MEMORY_TARGET.

显然上述Note在有一点上说错了,那就是设置memory_target参数无益于解决该UDE-31623问题;最好的做法还是显式地去设置streams_pool_size参数,但遗憾的是streams_pool_size虽然是一个可以动态修改的参数,但实际上是无法动态修改的:

SQL> col name for a20
SQL>
SQL> select name,isinstance_modifiable from v$system_parameter where name='streams_pool_size';

NAME                 ISINS
-------------------- -----
streams_pool_size    TRUE

SQL> alter system set streams_pool_size=60M sid='PROD1';
alter system set streams_pool_size=60M sid='PROD1'
*
ERROR at line 1:
ORA-02097: parameter cannot be modified because specified value is invalid
ORA-04033: Insufficient memory to grow pool

SQL> alter system set streams_pool_size=60M sid='PROD1' scope=spfile;
System altered.

Restart Instance .................

  1. 10.2.0.5中同样如此。而且10205中可以直接修改stream pool size,但是仍然必须重启实例,否则继续报错。

    SQL> alter system set streams_pool_size=60M;

    System altered.

    SQL> select COMPONENT,CURRENT_SIZE from V$SGA_DYNAMIC_COMPONENTS;

    这种情况下,datapump还是报错ORA-31623
