ALTER RESOURCE COST
Synopsis
ALTER RESOURCE COST [CPU_PER_SESSIONweight
] [CONNECT_TIMEweight
] [LOGICAL_READS_PER_SESSIONweight
] [PRIVATE_SGAweight
]
Modifies the formula used to calculate the session’s total resource cost. This cost may then be limited by the COMPOSITE_LIMIT parameter in a user’s profile.
Tip
The total resource cost is calculated by multiplying the amount of each resource used in the session by the weight assigned to that resource and adding the products for all four resources. The result is expressed in service units. You must activate the ALTER RESOURCE COST privilege to issue this statement.
