I've problem with db2fmp that consumes over 90% of CPU
I found some reference to set KEEPFENCED=NO that should solve this issue, but it doesn't help us.
We have several systems with the same configuration, but this one is the only one having problem.
I just did an upgrade from R3 470 ext 200 to ERP60 ehp4. I this system the downtime was ten hours, in an other system the downtime was 4 hours, db size is almost the same. I guess this process is one of the reasons.
