I am setting my datasource value in application.cfm with the following:
 
<cflock scope="Application" timeout="30" type="Exclusive">
  <cfif not IsDefined("application.DS")>
            <cfset application.DS = 'my_datasource'>
  </cfif>
</cflock>
 
Now in my application whenever I reference that variable (<cfquery name="X"
datasource="#application.DS#">) is it ok not to do a read only lock?  
Or do I need to lock it each time I call it?
The value of DS will never really change.
 
Thanks,
Scott
