Hello List,

I have a need to try an replicate a problem that has occured on our production environment. It seems that occassionally our response time dives to the buttom of the barrel in regards to our tuxedo application. When this occurs we have found that many of the blocked sessions are trying to query a sequence.

select my.sequence_list.next_value from dual

Does anyone know a possible cause for a sequence to be locked?

Does anyone know how to lock a sequence?

Thanks ahead of time.
