Learn Oracle Site Guard terminology.
The following terms are used throughout this document:
Target
Targets are core Enterprise Manager entities that represent the infrastructure and business components in an enterprise. These components need to be monitored and managed for efficient functioning of the business. An example of a target is an Oracle Fusion Middleware farm or an Oracle Database Instance. Oracle Site Guard disaster-recovery operations are designed to protect one or more targets at a site.
Site
A logical grouping of related entities in a data center. For example, software components in a Web tier, the Middleware tier, and Database tier, along with associated storage may all together comprise a Site. Oracle Site Guard performs disaster-recovery operations on a Site. A datacenter may have more than one Site defined by Oracle Site Guard and each of them can be managed independently for disaster-recovery operations.
Primary Site
The site currently hosting the active application (a set of targets) that Oracle Site Guard is configured to protect. The Primary Site is also referred to as the Production Site.
Standby Site
The site that is intended to host the protected application (a set of targets) in the event of a disaster-recovery operation.
Role
The current designation of a site. The role can be either Primary or Standby.
Switchover
The process of reversing the roles of the production site and standby site is termed as a switchover. Switchovers are planned operations done for periodic validation or to perform planned maintenance on the current production site. During a switchover, the current standby site becomes the new production site, and the current production site becomes the new standby site.
Failover
The process of making the current standby site the new production site after the production site becomes unexpectedly unavailable (for example, due to a disaster at the production site), is termed as a failover.
Open For Validation
The process of converting (opening) the current standby site into a fully functional site in order to test and validate operations at the standby site. When a site is opened for validation, it is not available as a standby site.
Revert to Standby
The process of reverting (closing) a site that has been opened for validation back to a standby site so that it is available as a standby site in disaster recovery operations.
Operation Plan
An operation plan contains the flow of execution for a particular Oracle Site Guard operation. It defines the order in which the steps of a disaster-recovery operation should be executed, in addition to other attributes, such as serial, parallel, and so on.
Prechecks
Prechecks are a pre-ordered set of checks that determine whether an operation plan is compliant with the environment it is supposed to protect. Prechecks are used to assess disaster-recovery readiness, and are performed on demand.
Health Checks
A pre-ordered set of checks, health checks can be programmed to run periodically based on a user-defined schedule. Health checks are used to maintain an ongoing assessment of disaster-recovery readiness.
Custom Precheck Scripts
Custom Precheck scripts are user-defined scripts that are executed as part of the Precheck procedure for an Oracle Site Guard operation plan. The number of Precheck Scripts and the sequence of their execution can be defined as part of an operation plan.
Pre Scripts
Pre scripts are site-specific, user-defined scripts that are executed at a site at the beginning of an Oracle Site Guard operation. The number of Pre Scripts and the sequence of their execution can be defined as part of an operation plan.
Post Scripts
Post scripts are site-specific, user-defined scripts that are executed at a site at the end of an Oracle Site Guard operation. The number of Post Scripts and the sequence of their execution can be defined as part of an operation plan.
Global Pre Scripts
Global Pre Scripts are operation-specific, user-defined scripts that are executed at the beginning of an Oracle Site Guard operation plan. The number of Global Pre Scripts and the sequence of their execution can be defined as part of an operation plan.
Global Post Scripts
Global Post Scripts are operation-specific, user-defined scripts that are executed at the end of an Oracle Site Guard operation plan. The number of Global Post Scripts and the sequence of their execution can be defined as part of an operation plan.
Execution Groups
Operation plan "Execution Groups" extend Site Guard's functionality for buckets (operation plan groups) whose Execution Mode setting is "parallel". Operation plan steps in the same execution group execute in parallel, but finish execution before any operation steps in a subsequently numbered execution group begin execution.
Tags
A tag is a user-defined alphanumeric string that can be associated with an operation plan. Tags can be used to search for operation plans that match one or more specified tags.
Super Administrator
A super administrator is a privileged user who has access to all Enterprise Manager targets, and to all Oracle Site Guard configurations, operations, and activities.
