SYSTEM tablespace defragmentation...

Hello DBA's !

I'm trying to defragment my poor system tablespace... Here is what I have done (hope is complete!):
- exp system/manager inctype=COMPLETE compress=Y full=Y grants=Y constraints=Y

• SQLDBA> shutdown
• tar cvf /dev/dat ./dbs
• mv ./dbs ./dbsOLD
• prepared a new ./dbs directory with init<name>.ora and sql.bsq (needed?)
• SQLDBA> startup nomount + connect internal
• SQLDBA> create database <name> ... (<name> is the same as the old one)
• SQLDBA> shutdown + startup open <name> + connect internal
• SQLDBA> created some tablespaces and rollback segments like the old ones

IMP-00003: ORACLE error 942 encountered
ORA-00942: table or view does not exist
IMP-00023: Import views not installed, please notify your DBA

WHY ?? What am I missing?
I have to create all the users and tables before to import the data? What about the DD tables?

Event with command: imp system/manager file=expdat.dmp show=Y I obtain the same message, so maybe my problem is in the exp file, but why?? At the moment I have reinstalled the old tared directory... :-( I hope to hear some good news from you!

Thank you for any hints,
Stefano
