Another division in our corporation jumped from V4R4 to V5R1 earlier in the 
year and they experienced massive performance problems.  They eventually 
performed the StrObjCnv on everything and they changed all of the Access path 
size from *MAX4G to *MAX1TB in all keyed files and logicals files, they were 
told by IBM to do this because the data from some database monitor jobs showed 
high contention for keys.

We are planning to go from V4R5 to V5R2 this weekend.  After reading the IBM 
upgrade manuals, they specifically state that a StrObjCnv on everything would 
not be necessary, that the conversion would only delay things about one second 
per file.

I believe I've read earlier that many people actually recommend running 
StrObjCnv on everything, but I don't think I've read about anyone changing 
access path sizes.

What has been your experience with these two issues?

Bill
