Re: [IDMS-L] DCMT D LOCKS STATS

Discussion created by ca.portal.admin on Jun 23, 2005
An update with new findings.

We have done some rough testing and found that a 'normal' condition would
overflow under control block Resource. When we have seen this before, we
have increased syslocks to handle our new limits.

This new case stems from varying a segment offline, with users still online
and others trying to gain access to the db. If an overflow has occurred
before in control block Resource it will further overflow in that control
block. If no overflows have occurred before it will now overflow in control
block Class.

Changing the vary offline to vary retrieval (as Steve suggested) stops the
overflow from happening or reduces the number of locks being acquired. This
is different behaviour in 16.0 than happened in 15.0.

We will change to vary retrieval unless we have to make the segment totally
unavailable.

Thanks

Chris
