Dynamically reconfiguring I/O tasks

When you increase the number of I/O tasks, there may be a slight lag before Adaptive Server balances the load across tasks. When you increase the number of disk I/Os, Adaptive Server quickly balances the distribution across the controllers. However, network tasks have an affinity between the connection and the task, so when you increase the number of network tasks, they are not rebalanced across the new higher number of tasks. Instead, Adaptive Server rebalances the load as existing connections disconnect and new connections are made.

You must restart Adaptive Server to reduce the number of I/O tasks.
