You shouldn't need to use a Session variable for your DSN .. especially if
you are going to be setting it over and over in your Application.cfm. That
defeats the purpose of having a Session variable anyway. You could get by
with another scope .. say Variables.ds, or something. That way, you
wouldn't have to worry about locking at all.
<cfif not IsDefined('Variables.ds')>
<cfset Variables.ds = "something_dev">
</cfif>

Subject: CFLOCK datasource var?
| In my application.cfm I set a session var for all my queries' datasource
| like this:
|
| <cflock scope="session" timeout="30" type="exclusive">
| <cfset session.ds = "something_dev">
| </cflock>
|
| So... Do I need to read-only lock every reference to session.ds in all my
| other templates where I have a query using that datasource session var?
| e.g.,
|
| <cfquery name="get_year" datasource=#session.ds#>
| select sysdate from dual
| </cfquery>
|
| Since session.ds is always identical for every user of this site, what
does
| it matter if it's locked or not?
