Adaptive Server provides resource limits to help System Administrators prevent queries and transactions from monopolizing server resources. A resource limit is a set of parameters specified by a System Administrator to prevent an individual login or application from:
Exceeding estimated or actual I/O costs, as determined by the optimizer
Returning more than a set number of rows
Exceeding a given elapsed time
The set of parameters for a resource limit includes the time of day to enforce the limit and the type of action to take. For example, you can prevent huge reports from running during critical times of the day, or kill a session whose query produces unwanted Cartesian products.
