HS_RPC_FETCH_REBLOCKING

Default value:	ON
Range of values:	OFF, ON

Controls whether Heterogeneous Services attempts to optimize performance of data transfer between the Oracle database server and the HS agent connected to the non-Oracle data store.

The following values are possible:

• OFF disables reblocking of fetched data so that data is immediately sent from agent to server.

• ON enables reblocking, which means that data fetched from the non-Oracle system is buffered in the agent and is not sent to the Oracle database server until the amount of fetched data is equal or higher than HS_RPC_FETCH_SIZE. However, any buffered data is returned immediately when a fetch indicates that no more data exists or when the non-Oracle system reports an error.
