Oracle官方推荐的数据迁移方式评估
APPLIES TO:Oracle Database - Enterprise Edition - Version 8.1.7.4 and later
Information in this document applies to any platform.
GOAL
To migrate an existing Oracle database (NOT BINARIES) from one Operating System platform to another (i.e. Windows to Solaris)
This can occur as part of an Oracle version upgrade (Oracle8i .. Oracle 11G) or within the same Oracle version: (Oracle 10.2 to Oracle 10.2).
Changes within an Operating System (ie: Linux,Windows or Solaris from 32 bit to 64 bit) are not considered cross platform migrations and are performed as normal version upgrades/wordsize conversions.
For details please refer to the appropriate migration manual or
NOTE:62290.1" alt="62290.1" title="62290.1" target="_blank">62290.1> - Changing between 32-bit and 64-bit Word SizesSOLUTIONThere is no migration utility (Script or DBUA) to perform a cross platform migration of an Oracle Database.
Changing platforms requires the database be re-built and / or the data moved using one of the followingmethods:
Export / Import to include the use of Datapump facilities. All versions support Export/Import but for Datapump 10.1.0.2 or higher is requiredTransportable Tablespaces 10G or LaterRMAN Convert Database functions. 10G or LaterRMAN DuplicateStreams ReplicationCreate Table As Select (CTAS)Dataguard Heterogeneous Primary and Physical StandbysOracle Golden Gate(For assistance with Oracle Golden Gate, an SR needs opened with the correct team)Each available choice will have strengths and limitations to include data types, time required and potential costs.
The choices available will depend on BOTH the Operating System and Oracle versions on both the source and destination.
For example:
There are platform limitations when using Dataguard Heterogeneous Primary and Physical Standbys
For more information please refer toNote: 413484.1Data Guard Support for Heterogeneous Primary and Physical Standbys in Same Data Guard Configuration
RMAN Convert Database only works if both source and destination belong to the same ENDIAN format.
RMAN Duplicate Database only works if both source and destination belong to the same ENDIAN format.
For more infomaiton on RMAn Duplicate please refer toNote: 1079563.1RMAN DUPLICATE/RESTORE/RECOVER Mixed Platform Support 1079563.1
RMAN's convert function for Transportable Tablespaces will convert from one ENDIAN format to another.
These two commands ARE NOT the same. Please refer to the notes at the end of the document for the correct note needed.
The following is the basic information for using Transportable Tablespaces:
Create an "empty" database in the new environmentPlug in all data tablespaces from source to target databaseSYSTEM+SYSAUX tablespaces can't be transportedAdditional steps necessary to move views, synonyms etc.Possibly very fast upgradeComplexity could be constrainingWorks cross-platform and cross-Endianness since Oracle Database 10g
The following is the basic information for using Oracle Streams in an upgrade:
