question on proxy with sql 2005

I am a recent user of sql2005 but have worked with sql2000 for a few years.
I noticed under the sql server agent there is a listing for proxy. I have
used the sql server agent to set up jobs to run packages developed with
Integration services. I was wondering if anyone had a simple explination of
proxys and how/why to set them up.
Thanks.

Paul,
My take on the proxy is if you need to run something from inside SQL that
needs to go outside of SQL you need the proxy account. So if an SQL process
needs to run xp_cmdshell then you need the proxy account. We have cases
where we start inside SQL and go outside to another server that runs a
process inside another SQL server. Here the proxy is needed to go outside
and needs to be defined on the other server and possibly given access to SQL
resources inside the other SQL Server otherwise it will not work.
Clear as mud!
To use xm\p_cmdshell you need to make it available SAC and give permission
to run it and then either create the proxy Under
Server/Properties/Security/Server proxy Account or by using the system sp
sp_xp_cmdshell_proxy_account. They both do the same thing.

|||Hi Chris, thanks for the information. I think it makes sense, will probably
try to set up an example when I have some time. I guess for example if you
wanted to run an Integration Services package on server two and some how
initiate it with a job on server one, the proxy acount might be used? Also
not sure if you have run into this but I have a 2003 web app and when I open
it from vs 2003I get the error message unable to get the project file from
the web server, the two need to map to the same server? thanks.

THE proxy Account certainly does xp_cmdshell but you can have others and
assign them to do different tasks. Looks at SQL Server/Agent/Proxies. You
can create these using Security/Credentials. This is the way to define a
proxy and what it can use. As I mentioned the xp_cmdshell is defined using
the Server/Properties/Security/Server proxy Account.
