We are creating a procedure in which we use bcp(xp_cmdshell) to archive out the data for particular month. When I execute procedure without begin tran/commit tran it works fine and bcp out the data from table to hard disk. But when i try to use transaction handling using begin tran the procedure keeps running, the bcp remains open and the procedure stucks and does not complete.

Is there any special way to handle transaction when using bcp and xp_cmdshell in the procedure?

This is the only procedure running on machine.

Thanks
