5 Managing Oracle VM User Domains

Oracle VM is a Xen-based virtualization technology, which is used across Oracle Exadata Database Machine systems that use InfiniBand Network Fabric.

• Oracle VM and Oracle Exadata
  When deploying Oracle Exadata, you can decide to implement Oracle VM on the database servers.
• Migrating a Bare Metal Oracle RAC Cluster to an Oracle RAC Cluster in Oracle VM
  
• Showing Running Domains
  
• Monitoring a User Domain Console
  
• Monitoring Oracle VMs with Oracle Enterprise Manager
  The Exadata plug-in for Oracle Enterprise Manager discovers, manages, and monitors virtualized Oracle Exadata Database Machine in conjunction with the Virtualization Infrastructure plug-in of Oracle Enterprise Manager.
• Starting a User Domain
  
• Managing Automatic Startup of Oracle VM User Domains
  By default, when you create a user domain, it is configured to automatically start when the management domain is started. You can enable and disable this feature as needed.
• Shutting Down a User Domain From Within the User Domain
  
• Shutting Down a User Domain From Within the Management Domain
  
• Backing Up and Restoring Oracle Databases on Oracle VM User Domains
  Backing up and restoring Oracle databases on Oracle VM user domains is the same as backing up and restoring Oracle databases on physical nodes.
• Modifying the Memory Allocated to a User Domain
  
• Modifying the Number of Virtual CPUs Allocated to a User Domain
  
• Increasing the Disk Space in a User Domain
  You can increase the size of Logical Volume Manager (LVM) partitions, swap space, and file systems in a user domain.
• Expanding /EXAVMIMAGES After Adding the Database Server Disk Expansion Kit
  With the addition of a disk expansion kit to the database server, it is important to follow proper procedures to add this additional space to the /EXAVMIMAGES file system.
• Adding an Oracle VM Cluster
  You can use Oracle Exadata Deployment Assistant (OEDA) to create a new Oracle VM cluster on an existing Oracle Exadata.
• Expanding an Oracle RAC Cluster on Oracle VM Using OEDACLI
  You can expand an existing Oracle RAC cluster on Oracle VM by adding user domains using the Oracle Exadata Deployment Assistant command-line interface (OEDACLI).
• Creating a User Domain Without Oracle Grid Infrastructure and Oracle Database
  
• Moving a User Domain to a Different Database Server
  User domains can move to different database servers.
• Backing up the Management Domain and User Domains in an Oracle VM Deployment
  
• Recovering an Oracle VM Deployment
  You can recover an Oracle VM from a snapshot-based backup when severe disaster conditions damage the Oracle VM, or when the server hardware is replaced to such an extent that it amounts to new hardware.
• Removing an Oracle RAC Cluster Running in Oracle VM
  You can remove all Oracle RAC nodes of an Oracle VM cluster, including the databases running within the cluster and all data stored on the Oracle Exadata Storage Server used by those databases.
• Removing a User Domain
  You can remove an user domain in Oracle VM using either OEDACLI or the domu_maker utility.
• Implementing Tagged VLAN Interfaces
  This topic describes the implementation of tagged VLAN interfaces in Oracle VM environments on Exadata.
• Implementing InfiniBand Partitioning across Oracle VM Oracle RAC Clusters on Oracle Exadata
  For Oracle Real Application Clusters (Oracle RAC) clusters running in Oracle VM on Oracle Exadata, you can isolate the network traffic on the InfiniBand network for each Oracle RAC clusters using custom InfiniBand partitioning, dedicated partition keys, and partitioned tables.
• Running Exachk in Oracle VM Environments
  Exachk version 12.1.0.2.2 and higher supports virtualization on Oracle Exadata.
