If you are running in archivelog mode and have all archivelogs
since the datafiles were created=2C then you can create the
datafiles and recover them completely even without a backup=2E

I have just tested it on HP-UX 8=2E1=2E7=3A

SQL=3E r
1 create tablespace test
2* datafile =27/tmp/test=2Edbf=27 size 10248 K

Tablespace created=2E

SQL=3E create table testtab
2 (f1 number)
3 tablespace test=3B

Table created=2E


SQL=3E insert into testtab values (111)=3B

1 row created=2E

SQL=3E insert into testtab values (222)=3B

1 row created=2E

SQL=3E insert into testtab values (333)=3B

SQL=3E insert into testtab values (666)=3B

SQL=3E commit=3B

Commit complete=2E

SQL=3E ! rm /tmp/test=2Edbf

SQL=3E select *
