models.oracle_data_guard_info module

class models.oracle_data_guard_info.OracleDataGuardInfo(role=None, mtype=None)

Bases: object

Implementation of the ‘OracleDataGuardInfo’ model.

Specifies information about the Database in Oracle DataGuard configuration. Data GUard provides a comprehensive set of services that create, maintain, and monitor one or more standby databases to enable production Oracle databases to survive disasters and data corruptions. Data Guard maintains these standby databases as transactionally consistent copies of the production databases.

Attributes:

role (RoleOracleDataGuardInfoEnum): Specifies the role of the

DataGuard database. Specifies the role of the DataGuard database.

A Data Guard configuration contains one production database, also referred to as the primary database, that functions in the primary role. The primary database can be either a single-instance Oracle database or an Oracle Real Application Clusters database.

A standby database is a transactionally consistent copy of the primary database. Similar to a primary database, a standby database can be either a single-instance Oracle database or an Oracle Real Application Clusters database. ‘kPrimary’ indicates that the current database is primary database. ‘kStandby’ indicates that the current database is standby database.

mtype (TypeOracleDataGuardInfoEnum): Specifies the type of standby

database. Specifies the type of standby database. ‘kPhysical’ indicates that the current database provides a physically identical copy of the primary database, with on disk structures identical to the primary database on a block-for-block basis. It is kept synchronized with the primary database, though Redo Apply, which recovers the redo data received from the primary database and applies the redo to the physical standby database. ‘kLogical’ indicates that the current database provides the same logical information as the production database, although the physical structure can be different. It is kept synchronized with the primary database thorugh SQL Apply, which transforms the data in the redo received from the primary database into SQL statements and then executing the SQL statements on the standby database. ‘kSnapshot’ indicates that the current database is a fully updateable standby created by converting a physical standby database into a snasphot standby database. It receives and archives but does not apply redo data from a primary database.

classmethod from_dictionary(dictionary)

Creates an instance of this model from a dictionary

Args:

dictionary (dictionary): A dictionary representation of the object as obtained from the deserialization of the server’s response. The keys MUST match property names in the API description.

Returns:

object: An instance of this structure class.
