Monitoring tools for locks and processed SQL queries?

Hello everybody

I’m trying to solve a performance problem in an application that’s
using ASE 12.5 as the database engine. I suspect that it’s due to
locking of tables for certain queries that puts other concurrent
queries on queue and if these queries takes some time the other
clients will stall.

Therefore I would like to know if there is a tool that allows me to
monitor, preferable in near real-time, locks on tables including lock
type and if possible also processed SQL queries.

Any help on this issue would be most appreciated.

Regards, Ola
