Hi experts.
At november 2014 we have migrate our platform from iSeries/DB2_400 to Wintel/ASE. The new server has 16 CPU, 64 GB RAM and flash disk.
The first months the performance of the system was fantastic, but since the 3th or 4th month it slow down more and more until now, when the performance is very very poor.
We have check lots of parameters, update ASE and kernel to the last version (kernel 7.02 SP500, ASE 15.7.0.133) but the problem persists. The only thing we can see at the dbacockpit is that from time to time there is a very poor performance at the I/O devices. Attached I send you an screenshot about that times. Can anybody sujects what can be the problem?.
