How to recover to keep tablespaces working after datafile deleted on OS

Question

hi,
given situation like this :
1. OS HPUX 11i
2. Oracle 9.2 or 10g
3. tablespace AAA have a datafile AAA.dbf
4. AAA.dbf has been deleted by a guy on OS by accident
5. it's a production database , i have other copy of product running elsewhere
6. we can forget about the data on this tablespace , just wanna make sure new data will still be inserted
I know there is a magic way involving file descritpor to recovery the file on OS if it was still opened by the process
seems it only works on linux or solaris , since HPUX don't have /proc
here is what i had done ,
1. offline drop the tablespace
2. export tablespace AAA from other DB without data but everything else
3. import them into DB without AAA now
only problem seems application couldn't insert into the tables ,Object priveledge not granted
i'd checked the export file , those object grant SQL are right there , i just don't know why import hasn't worked
so my question is
if it were you ,
1.do you have any better idea of how to recover
2.if you any dirty and fast way of recovery File on HP box , appreciate that too
3.can you image why import doesn't seems getting priveledge imported ? my DB version 9.2.0.4
many thanks

thanks , aman ,lenord and you all
looks like i'm the sinful :)
to clear it up ... it's not me who did it , one of our guys , same thing ,hum ~~
he deleted the backup , cause it's full and auto backup is not ongoing , and he's trying to make things right
he deleted the datafile , cause i told him to rename the file to another space , coz vgdb is full , screw up that too ..
yeah , it'a real production database ~~ , so ,if anybody learn somethings on this , credit on me , :)
the version is 9.2.0.4 , but gonna move to 10g soonor or later , so put it there , to see if in 10g , we can do better ..
tablespace created like five years ago , so , apply all archive since would be crazy ~
this database have 500 Tablespaces , and thoudsands of tables , and the one lost is a important one ,
but data in it , we can bear loss
what i do , is offline drop the tablespace , and import the tablespace without data from other production DB ...
only it didn't work out so well with object grant , and application still not inserting ...
why i post it here , is i wanna learn better ways in this kind of situations ...
i thought my way is not good enough
anway , i'll look at all your suggestions
thanks
