Hi Eduardo, could you please provide the content of your dsm.opt and dsm.sys? Also, are you trying to backup your database with scheduler or by hand from command line.
When you want backup one database with two different node names, you have to have correct environment DSMI_CONFIG,....(I assume your platform is Unix) for particular TSM node in user environment, who owns database instance. Are tou sure you are switching your environment correctly? Ing. Jozef Zatko Login a.s. Dlha 2, Stupava tel.: (421) (2) 60252618
