Zero Downtime Patching uses Fleet Patching and Provisioning to patch Oracle Grid Infrastructure without bringing down Oracle RAC database instances. Which three statements are true about Zero-Downtime Oracle Grid Infrastructure Patching? (Choose three.)

  1. Zero Downtime Patching requires out-of-place patching of Oracle Grid Infrastructure 19c with Oracle RAC or Oracle RAC One Node databases of 19c or later releases and only the binaries in the Oracle Grid Infrastructure user space are patched.
  2. When using Zero Downtime Patching, the root.sh script must be executed manually with -nodriverupdate option.
  3. When using Zero Downtime Patching, Oracle Grid Infrastructure OS system software, kernel modules and system commands including ACFS, AFD, OLFS, and OKA are not updated.
  4. Zero Downtime Patching requires in-place patching of Oracle Grid Infrastructure 19c with Oracle RAC or Oracle RAC One Node databases of 19c or later releases and only the binaries in the Oracle Grid Infrastructure user space are patched.
  5. Zero Downtime Patching can be fully automated by selecting the option to automatically run the root.sh script.

Question 13

  1. New allocation units are mirrored in the FG2 failure group until FG1 is restored and the disk group resynchronized.
  2. The redundancy is lowered until the FG1 failgroup is restored and the disk group resynchronized.
  3. New allocation units are not mirrored but changes to allocation units are tracked in the FG2 failure group.
  4. Transactions on database objects stored in tablespaces in the DGRP1 disk group fail.
