Hi,

we have metadata repository tier, services tier, engine tier and client tier, I just to know which tier architecture I am currently using, if each tier is installed in different servers then corresponding server and DB information, is there any way to find this, I am new to datastage, please note that I don't have any admin access I am developer.
Thanks in advance,
Regards,
Sudheer

Ask your admin what the topology is.

That information can also be obtained within your Version.xml.

But as qt_ky indicated, talk to your admin, he/she will be HAPPY that someone cares enough to ask.

When you log in to DataStage, you do so from the client tier. You specify the hostname of the services tier to authenticate your credentials. You specify the hostname of the engine tier when specifying the project to which to connect. If these three hostnames are all different, then the tiers are on different machines.

You don't really need to care about where the repository tier is located and, as an ordinary user, it's not all that easy to find out (other than by asking). This is really only within the purview of the administrator. It is (and should be) invisible to ordinary users.

There is a Version.xml file on each of the tier computers. Since a client install doesn't need to know anything about the other tiers, it's Version.xml won't have that information.

If you have access to your engine tier computer, its Version.xml should at least have something in it about the services tier host since the engine tier installation requires that information.
