A system copy is a duplicate of an SAP system. You re-install all instances of the SAP system, but create the target database as a copy of the source database (database copy). Some settings in the target system may be different from those in the source system.

Homogenous System Copy

The following conditions apply to homogeneous system copies with SAP MaxDB databases:

  • Source and target systems must both use SAP MaxDB as their database.

  • The databases on the source and target computers must have the same version in the first three places of the version number (7.<minor>.<servicepack>). The build level of the database on the target computer must be equal or greater than the build level of the database on the source computer (7.<minor>.<servicepack>.<build>)

    As of SAP MaxDB 7.6, the service pack level of the database on the target computer may be higher than the service pack level of the database on the source computer.

  • The computer on which the database of the target system is running must use the same byte order as the computer on which the source system is running (compatible process architecture).

    Example Example

    Database computer of the source system: Little Endian —> Database computer of the target system: Little Endian

    Database computer of the source system: Little Endian —> Database computer of the target system: Big Endian

    End of the example.

One of the steps in creating a homogeneous system copy is creating a database copy.

Heterogeneous System Copy

  • The target system may use a different database system than the source system.

    Example Example

    Database of the source system: Oracle —> Database of the target system: SAP MaxDB

    End of the example.

  • The computer on which the database of the target system is running may use a different byte order than the computer on which the source system is run.

    Example Example

    Database computer of the source system: Little Endian —> Database computer of the target system: Big Endian

    Database computer of the source system: Little Endian —> Database computer of the target system: Little Endian

    End of the example.
