The Question is: Would you define what Enq/Deq is from the Monitor Cluster/ALL monitoring utility. State if it is IO or process information. Thank You... The Answer is : MONITOR LOCK and particularly MONITOR DLOCK provide rather more direct (and detailed) access to the locking information that is visible via commands such as MONITOR CLUSTER/ALL. Please see topic 5270 for some background on locking, and on the $ENQ and $DEQ system services. This locking information is not particularly process activity nor I/O activity, it provides some statistics on the current level of coordination activity within the OpenVMS distributed lock manager (DLM). Relevent documentation on the DLM includes: http://www.openvms.compaq.com:8000/ 72final/6258/6048pro_042.html#startsubcommand_274 http://www.openvms.compaq.com:8000/ 72final/4477/4477pro_003.html#lockman_map http://www.openvms.compaq.com:8000/ 72final/5841/5841pro_050.html#synch_accs_res_chap
