importing TIR's objects into TIR
. . importing table "TB_TIR0ACO0"
IMP-00058: ORACLE error 1653 encountered
ORA-01653: unable to extend table TIR.TB_TIR0ACO0 by 256 in tablespace TS_TIR001
IMP-00028: partial import of previous table rolled back: 280588 rows rolled back

When I see Oracle Error, the action for this erro was:
Action: Use ALTER TABLESPACE ADD DATAFILE statement to add one or more files to the tablespace indicated

well it is neseccary to add new data file, even my datafile size is just 100 MB. I have Autoextended now to 512K. will this solve my problem or anyhow I have to add new data file for the tablespace.
