SHARED_SERVERS

Property	Description
Parameter type	Integer
Default value	`0`, meaning that shared server is not on. If you are using shared server architecture or if the `DISPATCHERS` parameter is set such that the total number of dispatchers is more than 0, then the default value is `1`.
Modifiable	`ALTER SYSTEM`
Range of values	The value of this parameter should be less than `MAX_SHARED_SERVERS`. If it is greater than or equal to `MAX_SHARED_SERVERS`, then the number of servers will not be self-tuned but will remain constant, as specified by `SHARED_SERVERS`.
Basic	Yes

SHARED_SERVERS specifies the number of server processes that you want to create when an instance is started. If system load decreases, then this minimum number of servers is maintained. Therefore, you should take care not to set SHARED_SERVERS too high at system startup.
