If your installation runs BMP - batch message processing - the answer is YES.

Listen to Sandy for the correct answer. BMP and MP programs can run at the same time. However your environment should also have DBRC installed to coordinate locking mechanisms and enable a decent recovery in case of a problem.
Please note that there are 2 types of 'Batch'; BMP and DL/I. If you are trying to run a DL/I (pure batch) program when the onlines are up you are asking for trouble. BMP is the way to go (as Sandy mentioned)
