thanks Andrew, I was afraid of that. ________________________________ From: thin-bounce@xxxxxxxxxxxxx [mailto:thin-bounce@xxxxxxxxxxxxx] On Behalf Of Andrew Wood Sent: 05 January 2011 22:27 To: thin@xxxxxxxxxxxxx Subject: [THIN] Re: SQL licensing for Data Store Citrix's method of accessing the datastore is classed by Microsoft as "middleware" for users iirc. So, you can either .. license per processor (Under this model, a license is required for each physical or virtual processor that is accessed by an operating system environment running SQL Server software. This license does not require any user licenses (CALs); or get a server license + a user cal for each citrix user (Under this model, a server license is required for each operating system environment running an instance of SQL Server software, as well as a CAL for user that accesses a server running SQL Server - that's each user, not each concurrent user.) Back in the day Citrix had a recommendation for SQL licensing which I've found here (http://support.citrix.com/article/CTX106176) which meant 30 odd users meant it was cheaper to get a processor license, 60 odd 2 processor license. So - what type of SQL licenses have you got If you've got processor licenses - happy days; otherwise you may be short.

Do we need a user CAL for every Citrix User that connects or is it every server as if its every user I could be moving back to Access or maybe SQL server express as I think that's free. Any thoughts ? thanks Ronnie Visit our website : www.ltai.ie __________________________________________ Lufthansa Technik Airmotive Ireland Limited. Registered in Ireland. Reg. No. 45999.
