The STREAMS_POOL_SIZE value helps determine the size of the Streams pool. SQL> alter system set streams_pool_size = (10%of shared pool size) scope = spfile; Oracle DataPump utility which is frequently used by many Database Administrators will in fact be using “Streams Pool”, this stream pool size will be assigned 10% of the size of the shared pool and will reduce the amount of the buffer cache.To avoid reduction of other memory structures sizes (shared pool,buffer cache) you need to configure the streams_pool_size with proper value as Data Pump operations will use streams !!! Being involved with EE helped me to grow personally and professionally. ALTER SYSTEM SET streams_pool_size=150m SCOPE=both; And re-run the Export or Import Data Pump job. We help IT Professionals succeed at work. Oracle 8.0.6: No such parmeter in Oracle 8.0.6. If SGA_TARGET is set to a nonzero value and STREAMS_POOL_SIZE is not specified or is set to a null value, Automatic Shared Memory Management uses 0 (zero) bytes as a minimum for the Streams pool. For Oracle Advanced Queuing, use the procedures in the dbms_aqadm package to control the amount of Streams Pool needed.
