在某些时候,需要删除掉手工删除19c RAC,重新安装,以下是比较简便的操作(root用户操作)
source /home/grid/.bash_profile crsctl stop crs systemctl disable oracle-ohasd systemctl stop oracle-ohasd systemctl disable oracle-tfa.service systemctl stop oracle-tfa rm -rf /etc/oracle rm -rf /etc/ora* rm -rf /u01 rm -rf /tmp/CVU* rm -rf /tmp/.oracle rm -rf /var/tmp/.oracle rm -f /etc/init.d/init.ohasd rm -f /etc/systemd/system/oracle-ohasd.service rm -f /etc/systemd/system/oracle-tfa.service dd if=/dev/zero of=/dev/asm_ocr1 bs=1024 count=1 dd if=/dev/zero of=/dev/asm_ocr2 bs=1024 count=1 dd if=/dev/zero of=/dev/asm_ocr3 bs=1024 count=1
