Re: Java (was: DFSORT - SMF Records - GMT To EST)

I doubt that there is a significant difference in CPU resources between running the JVM in JZOS vs BPXBATC**. Perhaps the differences that you are seeing have to do with not measuring all of the address spaces? For JZOS, the JVM will be in the same address space as the JES2 initiator. For

Andrew: Its been a while since I have looked at timings, but if I recall correctly the SRB time can be a killer depending on what you are doing. Also not to get into the middle of anything. DFSORT is *OPTIMIZED* for IO and it is FAST. So a simple assembler program can be slower that DFSORT

There is an article I found that provides information on using REXX to handle SMF Records. Looks like you might be able to use the DATE function in REXX to do what you want. Just a thought. http://ibmsystemsmag.com/mainframe/tipstechniques/applicationdevelopment/rexx_smf_part1/
