In this blogpost about the Oracle Cloud Infrastructure I will describe how to administer user, groups etc. Refer to the first blogpost Getting started with the Oracle Cloud Infrastructure for explain the first steps with the OCI.
A user in the OCI can access, create and administer cloud services. The permissions for users can be consolidated in groups as policies. Policies define the allowed actions for group members and in which department.
A Compartment is logical group of resources that represents an organizational unit. Resources will be created in a compartment. You cannot move the cloud resources from one compartment into another…

Some time I have the problem with the vies of the Top Activity Page in the Cloud Control:
The Graf shrink to left and you can see only the part of the picture:

Kernel-based Virtual Machine (KVM) provides a possibility to use the Oracle (or Redhat/CentOS) Linux kernel as a hypervisor.
In my example, I will configure the KVM virtualization on top of the guest vm running OEL 7.4. The guest VM is running on top of the VMWare Workstation 12.
To enable the virtualization layer select VM settings and navigate to the Processor settings. Enable the setting „Virtualize Intel VT-x/EPT or AMD-V/RVI.“
The Guest VM is now enabled for the using of the nested virtualization (such kvm). Start the Guest VM.
Install and configure KVM virtualization on the OEL 7.4 Linux

Do you know the problem: an Exadata does not have enough space in filesystem /u01? The Exadata has the locale storage and you can increase /u01.
1. Check filesystem and associated volume:
[root@myexadb01]# df -h
Filesystem Size Used Avail Use% Mounted on
/dev/mapper/VGExaDb-LVDbSys1 30G 23G 5.7G 80% /
tmpfs 757G 4.0K 757G 1% /dev/shm
/dev/sda1 488M 48M 405M 11% /boot
/dev/mapper/VGExaDb-LVDbOra1 158G 107G 43G 72% /u01
Check the free space in the volume group:
PV VG Fmt Attr PSize PFree
/dev/sda2 VGExaDb lvm2 a—u 1.63t 1.38t
