Hi I am new to datastage .. I have 1 trasform routine which have following orchadmin command
/team_uno/power/Server/PXEngine/bin/orchadmin dump /data/san/team.ds 2>> /dev/null

The "orchadmin" command is documented. the "dump" option does exactly that, it dumps the contents of the DataSet to standard output. This command doesn't modify the dataset at all, just does the DataStage equivalent of a "cat" of the contents.

just to understand more what the significance of "2"after dataset name. And what is /dev/null

You asked two UNIX questions;
2 is stderr
/dev/null is a special UNIX file or null device. It discards all data written to it. In this case it is getting rid of any errors being written by the previous command.

/dev/null also means write to a black hole
