-- [ Picked text/plain from multipart/alternative ] Hi, I have a situation where a particular part of an overnight process is taking much longer to run on a more powerful system, and wondered if anyone might offer any suggestions as to why this may happen. The remaining parts of the process are running more or less the same length of time, or slightly better. For one program that is called within the process, the elapsed run time is 1.5hrs on System A whereas it is 8.0 hrs on System B. In both cases the job is run overnight when there is not much other activity on the system. The job has been run several times with the same results, on each system. System A is a 4-way system, system B is a 12-way system. Both are on the same version of OS/400 with the same CUM PTF's applied. The subsystem descriptions should be similar and both run in the base pool. I am waiting to hear if SMP is installed on either/both (DB2 Symmetric multiprocessing), but since it is an RPGLE program, I don't think this will make a difference anyway. The program is performing input-primary processing on a join logical based on three physical files. There is one format in the join logical. There are 11 million records in each of two of the joined files, and around 100,000 in the other. The data has been restored from one system to the other so it is identical. Any ideas ?? Thanks in advance! Nigel
