Issue

• After upgrading the systems to RHEL 9.6, there is a corruption observed with Oracle redo logs:

  Even rebuilding the redo logs does not fix the corruption.

• This issue is only observed for VMs configured in Microsoft Azure. Same problem is not observed for VMs in other virtualization environments or on physical servers.
