Initialization Parameters, 184 of 188

TRANSACTIONS

Parameter type:	Integer
Parameter class:	Static
Default value:	Derived (1.1 * `SESSIONS`)
Range of values:	4 to 2³²
Oracle Parallel Server:	Multiple instances can have different values.
`TRANSACTIONS` specifies the maximum number of concurrent transactions. Greater values increase the size of the SGA and can increase the number of rollback segments allocated. The default value is greater than `SESSIONS` (and, in turn, `PROCESSES`) to allow for recursive transactions.
