CURSOR_SPACE_FOR_TIME
lets you use more space for cursors in order to save time. It affects both the shared SQL area and the client's private SQL area.
Values:
TRUE
Shared SQL areas are kept pinned in the shared pool. As a result, shared SQL areas are not aged out of the pool as long as an open cursor references them. Because each active cursor's SQL area is present in memory, execution is faster. However, the shared SQL areas never leave memory while they are in use. Therefore, you should set this parameter to TRUE
only when the shared pool is large enough to hold all open cursors simultaneously.
In addition, a setting of TRUE
retains the private SQL area allocated for each cursor between executions instead of discarding it after cursor execution, saving cursor allocation and initialization time
FALSE
Shared SQL areas can be deallocated from the library cache to make room for new SQL statements.
