It will simply eat up CPU cycles waiting for data to appear. Even without data you can confirm that at least those portions of the code are running properly. And, you can certainly try the configuration, although you won't be able to tell if you've configured it properly until your upstream feed is turned on. Here are a few things you can do to verify that what you've got so far is working: 'ldmadmin ps': should show you that there are a few processes owned by ldm that are running. You should see at least one rpc.ldmd process. When you put 'exec pqact' in your ldmd.conf file you should also see one pqact process. 'ldmadmin pqactcheck': will check that the syntax in your pqact.conf file is (mostly) correct 'ldmadmin tail': will show the end of the current log file 'ldmadmin config': shows the LDM's configuration Anne -- *************************************************** Anne Wilson UCAR Unidata Program address@hidden P.O.
