Oracle DUL Operating System Dependent Parameters OSD Operating System Dependent Parameters

the osd header is endian specific. Remember that the settings should be

for the original database platform. So this only requires some attention when cross unloading. For instance when

unloading from a Solaris Sparc, or AIX machine on your laptop.

Older versions before Oracle 10g

Before 10g there are some subtle differences between the platforms. Its related to how the various compiler packed

C-structures, the number of bits for a file and a block number in a dba, disk block address, and the size of the osd

header block (block 0). All these could be different. Netware is the exception as they forced a rebuild of all databases

in the transition from Oracle7 to Oracle8, so for that platform there are two sets.
