Hi, I have installed the datastage 7.5 in XP operating system, also installed visual studio .net 2008 for c++ compiler. But when trying to compile the datastage job which contain the transformer stage, I am unable to compile. Below warning I am getting: Warning: the PWD environment variable is not defined. Remote process start up may be unsuccessful as a result.If your ORCHESTRATE job does not start up correctly, please set your PWD variable to a value that will work on all nodes of your system. Please help me out.. Thanks in advance.
