Hi

Exact steps are:

1) alter tablespace tools offline
2) shutdown immediate
3) move the file on os-level
4) startup mount this failed
5) Here I wanted to exec the rename 

I know it's weird but this really happened and When I tried this with a new testdb again and used alter tablespace name Offline normal it worked.

did you also rename the datafile within the database? the error message on the line starting with ORA-01110 tells you that the database thinks the file should be at /migratie_deca/DECA/DATA. If that is the original location, that should tell you that as far as Oracle is concerned the datafile is in the original location. You have to tell Oracle where you moved the file, the database is smart but not omniscient.

in addition to the "alter tablespace offline" (and no, I've NEVER had to do this with the "normal" clause) you need to do an

alter database rename file '<old file name including path>' to '<new file name including path>' before you do the mount
