Between which operating systems are homogeneous system copies and the structure of a standby database scenario possible?
Homogeneous system copies may only be carried out between systems with the same operating system. Standby databases must also run on the same operating system as the primary database. Differences within an operating system are generally allowed: ITANIUM vs. non-ITANIUM; with the exception: On HP-UX, standby databases and system copies with online backups are not allowed between ITANIUM and non-ITANIUM. Different releases (for example, AIX 4.3 versus AIX 5.2); with the exception: you cannot combine HP-UX 10.20 and HP-UX 11.0 or higher. You can only change from 32-bit to 64-bit or vice versa on the basis of an offline backup, while the use of an online backup is not supported. You are also not allowed to restart a 64-bit standby database with a 32-bit primary database and vice versa.
