STREAMS_POOL_SIZE

Property Description
Parameter type Big integer
Syntax STREAMS_POOL_SIZE = integer [K | M | G]
Default value 0
Modifiable ALTER SYSTEM
Range of values Minimum: 0 (values greater than zero are rounded up to the nearest granule size)

Maximum: operating system-dependent


Oracle's Automatic Shared Memory Management feature manages the size of the Streams pool when the SGA_TARGET initialization parameter is set to a nonzero value. If the STREAMS_POOL_SIZE initialization parameter also is set to a nonzero value, then Automatic Shared Memory Management uses this value as a minimum for the Streams pool.

If the STREAMS_POOL_SIZE initialization parameter is set to a nonzero value, and the SGA_TARGET parameter is set to 0 (zero), then the Streams pool size is the value specified by the STREAMS_POOL_SIZE parameter, in bytes.

If both the STREAMS_POOL_SIZE and the SGA_TARGET initialization parameters are set to 0 (zero), then, by default, the first use of Streams in a database transfers an amount of memory equal to 10% of the shared pool from the buffer cache to the Streams pool.
