About this book  Dump and load across platforms with the same endian architecture


Chapter 1: Dumping and Loading Databases Across Platforms


Overview

Adaptive Server Enterprise version 12.5.2 supported the dump and load of databases across platforms with the same endian architecture.

With Adaptive Server version 12.5.3, you can now dump and load databases across platforms with different endian architecture. This means you can perform dump database and load database from either a big endian platform to a little endian platform, or from a little endian platform to a big endian platform.

In a big-endian system, the most significant byte of storage, such as integer or long, has the lower address. The reverse is true for a little-endian system.

There is no syntax change with dump or load database in version 12.5.3. Adaptive Server automatically detects the architecture type of the originating system of the database dump file during a load database, then performs the necessary conversions. Loads from older versions, such as 11.9 and 12.0, are also supported. The dump and load can be from 32-bit to 64-bit platforms, and vice versa.

Platforms supported:

Big-endian

Sun Solaris

IBM AIX

Silicon Graphics

HP-UX on HPPA, HPIA

MAC OS X

Little-endian

Linux IA

Windows

HP True 64*

Sun Solaris x86

* On True64, the XPDL feature does not work as the backupserver dump is incompatible with other platforms. This issue will be fixed in a future maintanance release.
