Re: Possible performance problems.

Thanks for the answers to the below problem (and check QFRCCVNRST 
sys value). The system value was set to '0' and the RSTLIB command
was set to *SYSVAL. As for object/release conversion I may expect
a slight degradation, but 10 hours for just including access paths! !
Anymore ideas would be much appreciated.
