Access OPtions Advance - refesh and lock settings.

Please could someone recommend settings for the Access Option Advance settings relating to refresh and locks in a multi-user environment with each user having a front end on their local PC and the back end in a central folder on the LAN- PLEASE SEE ATTACHED SNIP for the values I mean.

Does anyone have something with really explains in detail the difference they make - I am wondering is record size is an issue.

Many thanks,

The settings you have for Record Locking (No Locks) will produce the best results.  You may need to up the values for  Number of Update Retries and/or Update Retry Interval ... if you have encountering a lot of Write Conflicts.

I highly recommend you read the following KB's on record locking, as the subject is very confusing:

To be sure, set the default open mode option to: Shared

Office Button-->Access Options-->Advanced-->Advanced-->Default Open mode
rest is fine

Its basically the locking strategy you want to use and the timeout in case of a deadlock.. Wikipedia for basic terminology...

In terms of record size, no there should not be a problem...

There is no reason to change the defaullts unless you are sure they do not work for your application.

Thanks for all your help.

I asked this due to the problem I identified, details  here: http://www.experts-exchange.com/Microsoft/Development/MS_Access/Q_26872052.html that Jim Detman has taken to Microsoft.

I thought I might be missing something - at least I understand this section better now. I have always just used the settings above (with the shared mode as default) and had no problems until the issue with memo fields in the question on the link here.

Thanks again!
Lou
