MAX_ENABLED_ROLES

Parameter type	Integer
Default value	20
Parameter class	Static
Range of values	0 to 148

MAX_ENABLED_ROLES specifies the maximum number of database roles that users can enable, including roles contained within other roles.

The actual number of roles users can enable is 2 plus the value of MAX_ENABLED_ROLES, because each user has two additional roles, PUBLIC and the user's own role. For example, if MAX_ENABLED_ROLES is set to 5, user HR can have seven roles enabled: the five enabled by MAX_ENABLED_ROLES, plus PUBLIC and HR.
