The Question is: Many of my users are having 'waiting on lock' messages on screens. Researching the problem I found out (via monitor lock and dlock) that the rate of ENQ and DEQ vary from 200 to several thousands in average (same for DEQ) What are normal rates for these p arameters? Also I increased the ASTlm value which seems to aleviate the 'waiting on lock' problem. The only applicatin we run is Cognos Powerhouse on Alpha 20DS. Can you direct me to areas where I can find more info about 'waiting on lock' issues? Jorge Melazzini The Answer is : Lock waits are not necessarily associated with lock rates -- lock waits can occur at exceedingly low locking rates, or at exceedingly high lock rates. There is no particular correlation, the central factor hereare the incidents of lock collision; the blocking lock(s). Please contact the HP customer support center or the Cognos support organization, as the specific error message is required - this may be an application message, a third-party product message, a layered product message, or an OpenVMS message, and without the exact text there can be no certainty. The only immediately-similar OpenVMS message should not arise in the context of user operations: LOCKWAIT, waiting for locks on system disk You will also want to review the installation and configuration documentation for the products in use at the time of the error, looking specifically for process quota and/or system parameter settings recommendations and/or requirements. Please also ensure -- and as is typically requested -- you have the current mandatory ECO kits installed, and any locking, file system or cluster-related ECO kits installed. Also please check with the Cognos support organization for information on any Cognos kits that might potentially be available and/or required.
