I monitor for changes and from time to time I would get something like this.

            [streams_pool_size] changed from [0] to [335544320]

            [db_cache_size] changed from [1073741824] to [738197504]

From the pfile create from spfile I would get




I do not have Automatic Shared Memory Manager enabled.
