Need to move a new datafile from one tablespace to another tablespace [message #332514]

I forgot to select from the drop down list the appropriate tablespace name whenever I created a new datafile. The datafile path is the correct path information ... but it was put under the tablespace name of DI_DATA and it should be under tablespace name of MDATA_DATA. The path of the datafile name that is under the DI_DATA tablespace ... is /pds_oracle/u05/oradata/pdsprod/mdata04.dbf.

I have tried to take the datafile off line and it will not let me do this. I have tried to drag and drop the datafile into the correct tablespace name ... but I have had no luck.

Please advise.

Thank you ... Donna

You can not drop a datafile from a tablespace with 9i. In this case, you can rename the file to something else and then create the file under the appropriate tablespace. The only way to delete the erroneous datafile is to recreate the tablespace.

In addition, a datafile cannot be moved from one tablespace to another one. A datafile is definitively owned by the tablespace in which it is created.

Thanks for the information ... I have one other question ... I am new to Oracle ...

I tried to change the name of the datafile:

From : /pds_oracle/u05/oradata/pdsprod/mdata04.dbf
To : /pds_oracle/u05/oradata/pdsprod/di_data02.dbf

I received the following message and it would not allow me to change the name ...

Note: I did not take the datafile offline ... because I did not know what kind of affect it would cause.

Message Received:

ORA-01511: error in renaming log/data files
ORA-01121: cannot rename database file 29 - file is in use or recovery.
ORA-01110: data file 29:
/pds_oracle/u05/oradata/pdsprod/mdata04.dbf

My thoughts are ... maybe I should put the datafile in offline status ... first ... but I want to verify this before I move forward. Thanks for any advise. Donna

Yes, you have to put offline the file before moving it.

I tried to put the datafile in the offline mode ... but whenever I selected apply ... I received the following message:

ORA-01145: offline immediate disallowed unless media recovery enabled.

I am not sure ... what this means ... I will say that I only have "Oracle Enterprise Manager" (Standalone version) working at this time. Is it possible for me to set the media recovery to enabled?

Thanks, Donna
