Re: SYSGEN Parameter LOCKDIRWT
And put a comment there indicating when and why it was changed. You will thank yourself then next time you go back.
Note: It isn't a dynamic parameter, so you are going to need to reboot for it to take effect.

Re: SYSGEN Parameter LOCKDIRWT
pardon my indiscretion, but are you SURE you want to fiddle with LOCKDIRWT? ie, do you KNOW what you are doing?
LOCKDIRWT is great (and practically mandatory) when you have satellites in your cluster, otherwise, just do not meddle with it. It has been some time (V5 timeframe), but we have had "interesting" results with it.
Proost.
Have one on me.

Re: SYSGEN Parameter LOCKDIRWT
All 4 nodes are boot nodes. Three of the nodes have a LOCKDIRWT setting of 1, and one node has a setting of 0. None of these nodes are satellite nodes. I have received complaints regarding slow disk i/o performance specifically on the node with LOCKDIRWT set to 0. This was overlooked last summer when the cluster was upgraded to OpenVMS 8.2.
Hopefully this explains my situation much better.

Re: SYSGEN Parameter LOCKDIRWT
You need to check MODPARAMS.DAT (and any files it includes) for a setting for LOCKDIRWT. MODPARAMS will be used next time the system is autogened.
Manually, you can change LOCKDIRWT using either SYSGEN or SYSMAN.
Before doing so, I recommend that you review the OpenVMS Cluster Manual, section 2.6.2, available from the OpenVMS www site at http://www.hp.com/go/openvms (or your friendly CDROM or library shelf).

Re: SYSGEN Parameter LOCKDIRWT
Ya modify it to 1 from 0 manualy its better.
LOCKDIRWT determines the portion of lock manager directory that
this system handles. The default value is usually adequate.
LOCKDIRWT is an AUTOGEN parameter.
Thanks
and give points to this as per satisfaction of your question by this answer.

Well, obviously the warning "do not meddle" was already overdye.
That node witt LOCKDIRWT 0 -has been- meddled with.
Reverse it (set it equal to the others) until you have very good, and well understood, reasons to deviate.
(do not forget to check (& correct) MODPARAMS.
