Hi Jaafar,
Please be aware that OSS note 1508357 you'll be applying is applicable for DB2.
As other colleagues this one seems fit to your scenario. Did you try it?
1848921 - Errors caused by report RSDB2DAL after applying support packages
Also I would recommend to clean you monitoring tables via this function module (sm37):
SWNC_COLLECTOR_CLEAN_SWNCMONI
And you could have a look at TCOLL table via se14, whether it has some weird entries.
Regards,
Serhat
