Dear Maojun Wang, The LDM system can be used to transmit files from one computer to another. The LDM on the upstream computer can run a script via an EXEC entry in the LDM configuration-file. This script can monitor one or more directories for new files. When it sees a file, the script can use the pqinsert(1) utility to convert the file into an LDM data-product and insert that data-product into the LDM product-queue on the upstream computer. The LDM on the downstream computer can subscribe to such data-products via a REQUEST entry is the LDM configuration-file on the downstream computer. The situation I've described is used in many locations to transmit files. > Dear Sir, > This is Maojun Wang,and I`m try to use LDM to translate our data product > between two different computers.Now I have a question: > > > > 1 Now We have developed a program p01 to monitor dir001 on ServerAThe program > p01 use pqinsert to send new file to LDM as long as new file comes into > dir001. > > 2 I don`t know whether the LDM can do what the program p01 has done.If the > LDM can make it,please tell me. > > > Thank you very much!
