Parameters

Description |
|---|---|
|
_LARGE_POOL_MIN_ALLOC |

|
_USE_ISM |

|
OPEN_CURSORSOPEN_LINKSMAX_ENABLED_ROLES |
These parameters affect the size of the fixed UGA. They should not be any larger than necessary. |
|
PRE_PAGE_SGA |
If set to TRUE, this causes all Oracle server processes to page in the entire SGA on process startup if necessary. This may yield ... |
