Like 10 - 20 longer (!) on a massively configured production LPAR vs. even a puny little sandbox. Diagnostic data--sorry I don't remember the mechanism--point to GRS. The one obvious difference was that the problem system was the only full parallel sysplex *not* using GRS star. This system had been sysplexed some time earlier in order to debug some DB2 issues, but the 'other' member was not being IPLed on a regular basis. In other words, a single parallel sysplex capable system running in practice by itself in GRS ring mode. Taking the duh! approach, we converted the problem system/sysplex to GRS star. The GRS delays disappeared immediately, making the system look just like all the rest. Just another thing to look at. . .

On a catalog report all numbers Across the board are extremely higher..especially the mvs and bcs allocate.

What is your main delay reported by RMF ?

Job used to execute in 4 minutes now Takes 20...Only that one job. A couple of jobs running snap, are taking a bit longer as well. Is everybody running with the Catalog auto tune on? I am just grabbing at straws. Any insight or thoughts would be greatly appreciated.
