Hi Jimmy,

Oracle 7.4? Is that Oracle 7.3.4 or Oracle 8 (went to an Oracle 8 New Features course, where the instructor admitted that Oracle 8 could be better be called Oracle 7.4) :)
1) I usually do that because often a) I want to reorganize b) I don't want to get rid of the old db immediately.
Tablespaces are only created correctly if a) you created that second rollback segment in the system tablespace immediately after db creation
b) you specify destroy=y on the imp commandline. Otherwise it will detect the files are there and refuse to create them. Destroy=y is equivalent to create tablespace xyz datafile abc reuse. 2) I don't see why they would be skipped. They are in the export, they have tablespace system in their create statements, what would you expect? If you want to relocate them do the following

a) make sure the default tablespace of the user is not system
b) make sure the user doesn't have resource privilege
c) make sure the user has quota on the destination tablespace only
(alter user <user> quota unlimited on <destination tablespace>;)
