Hi, I saw my local hdd increase rapidly. So i check on /u01 and found too many dump file on /u01/app/oracle/product/admin. In that folder in contain subfolder call +ASM and MISSION. FYI, MISSION is my oracle db sid. If i delete the file in those folder, what would happen? I saw something is ASM manager refer to /u01/app/oracle/product/admin/+ASM. Is those file necessary or just dump file that can i delete? Please explain what are kind of file is it. Thank you. p/s: Sorry if post wrong section.
