What is execution preference?

Suppose you decide that slower response time is okay when login A uses isql, but that login B must be able to get results from isql as fast as possible. In this case, you would be willing to sacrifice response time for login A to enhance response time for login B.

You can do this by assigning an execution class, which is a collection of attributes representing task priority and engine affinity. You can tell Adaptive Server that you want it to give preference to login B when it executes isql by binding Login B to the preferred execution class EC1 with a scope of isql.

See “Managing execution classes” for more information.
