Event 215 is a common wait event. The value for Waits for event 215 is typically large. Busy servers have high values for WaitTime because processes are waiting for the Adaptive Server runnable queue for a long time. Reduce the value for time slice to allow more processes to access CPU (this also reduces the average time some processes spend in the CPU) or, if there are sufficient CPUs available on the host machine, increase the number of online engines.
