ORA-31687: error creating worker process with worker id 1

Datapump匯入資料的時候報錯：

Connected to: Oracle Database 11g Enterprise Edition Release 11.2.0.1.0 - 64bit Production
With the Partitioning, OLAP, Data Mining and Real Application Testing options
ORA-31626: job does not exist
ORA-31687: error creating worker process with worker id 1
ORA-31687: error creating worker process with worker id 1
ORA-31688: Worker process failed during startup.

 

 

在MOS上找到官方解釋：

Changes
In the first situation AQ_TM_PROCESSES=0

For the second situation AQ_TM_PROCESSES should not be 0.
Cause
For the first situation, AQ_TM_PROCESSES init.ora parameter was set to zero (AQ_TM_PROCESSES=0)

Once removed this parameter from the init.ora file, and bounced the database the problem was resolved

For the second situation, there is likely a lack of memory for the streams_pool_size.
Solution
For the first situation:
o  Remove AQ_TM_PROCESSES init.ora parameter (AQ_TM_PROCESSES=0) from the init.ora.

For the second situation:

o  Allocate between 50-100MB for the STREAMS_POOL_SIZE in order for datapump to function since it is dependent on streams processing.
