System Copy

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>.<support_package>). The patch level of the database on the target computer must be equal or greater than the patch level of the database on the source computer ( 7.<minor>.<support_package>.<patch_level>)

  As of SAP MaxDB 7.6, the support package level of the database on the target computer may be higher than the support package 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

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

  Database computer of the source system: Big Endian -> Database computer of the target system: Big Endian

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

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

• 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

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

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