Locking in CF5 (and earlier) was used for 2 reasons - to prevent the server from getting... err... confused (and crashing) and for 'logical' reasons. You no longer need to use cflock to prevent the server from crashing. However you may still need to use locks for logical reasons.
Example 1: Imagine Application.DSN stored your datasource. This value is set once and never changes. Therefore, you don't need to lock the creation or use of it. You did in CF5. Example 2: You store the # of hits to the site in Application.Hits. Your Application.cfm file does: <cfset application.hits = incrementValue(application.hits)> It's possible that two threads could run this code at the same time. Instead of starting off w/ 10 and ending up w/ 12, you would end up w/ 11. So, a lock could be used to ensure that you get the correct data. ======================================================================= Raymond Camden, ColdFusion Jedi Master for Macromedia Email : [EMAIL PROTECTED] Yahoo IM : morpheus "My ally is the Force, and a powerful ally it is." - Yoda > -----Original Message----- > From: Jim McAtee [mailto:[EMAIL PROTECTED]] > Sent: Monday, July 08, 2002 2:16 PM > To: CF-Talk > Subject: Re: nuther lockin Q? > > > How has locking changed in CFMX so that it's no longer > required in this > situation?
