Default value	Derived: (1.1 * `SESSIONS`)

Real Application Clusters	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.
