Re: [U2] [UV] Deadlock report ?
Take a look at analyze.shm (see the 'Administering Universe manual), IIRC the -r option in particular should give you just the record locks.

Re: [U2] [UV] Deadlock report ?
I'm already familiar with the -r option of analyse.shm but it is the equivalent to: LIST.READU EVERY. I only need this part: Active Read Waiters: Owner Waiter Device Inode Userno Userno 107400397041292 671 547 I an extract this part from the output of analyse.shm but this report takes a lot of time producing all of the grouplock and record lock information. Ideally, i'd need a switch to give me only this part + the key or group where the problem is occuring. - Original Message From: David Scoggins dscogg...@gmail.com To: u2-users@listserver.u2ug.org Sent: Monday, February 23, 2009 9:59:29 AM Subject: Re: [U2] [UV] Deadlock report ?

Use this verb. LIST.QUEUE [USERNAME user_name | FILENAME filename | user_number][DETAIL] Synonym LIST-QUEUE Description The ECL LIST.QUEUE command lists processes that currently waiting for locks. If a process is waiting for a lock, LIST.QUEUE displays information about the holder of the lock and processes waiting for the lock. Locks are set by each udt process through the general lock manager (GLM) module. UniBasic commands that check for locks, such as READU and READVU, cause processes to wait for locks to be released before proceeding.

Re: [U2] [UV] Deadlock report ?
On UV I don't seem to have a LIST.QUEUE command; is it possible that this is a UD feature? I wish there were a UV equivalent, like the D3 LIST-LOCKQ command. /Scott Ballinger Pareto Corporation Edmonds WA USA 206 713 6006 On Mon, Feb 23, 2009 at 10:11 AM, Nick Gettino nick.gett...@enroute911.comwrote: Use this verb.
