I have SAP IDES installed on windows server 2008 R2 with oracle database version 184.108.40.206.0 on the same server with 2 drives C and D. SAP is installed on C-drive and paging is configured on C-drive as 20480-3000MB. Oracle DB is on D-drive. My disk utilisation is always on 100% even if there are no users on it except myself. I have tried changing parameter PHYS_MEMSIZE to 8000MB as well 5000MB with no change. I have read SAP notes suggesting PHYS_MEMSIZE to be 50% of assigned memory. The assigned memory to the hyper-v server is 12GB. The disk utilisation is causing the system to slow down even logging in through the GUI or executing any transaction. I have run ST06 and ST02 please see attached info. I am aware performance is a big issue but I just need help where to tweak on this high disk utilisation. Both drives have 75% free space.
