The Streams pool is a portion of memory in the System Global Area (SGA) that is used by Streams. The Streams pool stores buffered queue messages in memory, and it provides memory for capture processes and apply processes. The Streams pool always stores LCRs captured by a capture process, and it stores LCRs and messages that are enqueued into a buffered queue by applications or users.
