RE: database clone:

On the "I have heard that in version 9i, you can, in fact create a standby database"
it it is not possible in the current release of 9i. This is called a Logical Standby. 9iRel1 provides only a Physical Standby. 9iRel2 (due in May/June) might provide Logical Standby. However, of course, this option is not available for Mitchell's requirement as it would not work against an 8.0.5 source database.

Mitchell,

I have not been following the thread, but nonetheless, I will attempt to add
some information. It is accurate to state that imp/exp is your only option in 8.0.5 when you are trying to move a database from one platform (AIX) to another (Solaris).

Other options all up through version 8.1.7 only apply when the platform is not changing:
e.g. Transportable tablespace
Standby database
or RMAN Hot Backup/Recover from disk or tape.

I have heard that in version 9i, you can, in fact create a standby database on a different platform because it actually converts the redo logs into SQL type DML/DDL statements and applies them, but even this is no way to re-create a 300 Meg database.

Of course, your option of imp/exp would be VERY time and resource intensive.

HTH,
-Ron-
