TABLESPACE creation error

Question

I have an error "ORA-01537" when I create a tablespace.

create tablespace "VOLUMT" datafile 'VOLUMT.dbf' size 250M autoextend on;

Then, it shows like following.

ERROR at line 1: ORA-01537: cannot add file 'VOLUMT.dbf' - file already part of database

I just change the tablespace name of VOLUMT to TEST01, and it works..

Tablespace created.

So, I get into the directory of db and searched the related tablespace..

${HOME}/oracle/db/oradata/ORAC12

However, I can't find any.. Coudl you help me to solve this problem? Also I need to use "VOLUMT" for tablespace creation.. not TEST01..

-- Additional --

select TABLESPACE_NAME from DBA_DATA_FILES;

TABLESPACE
----------
SYSTEM
SYSAUX
USERS
TEST01

I can see TEST01 Tablespace, but I can't find any datafiles in the directory. Also I can't find any VOLLMT tablespace in it..

Thank you.

Answer 1

The solution to your issue can be:

create the tablespace named as VOLUMT , but for the file name change it a bit like VOLUMT1.dbf or else specify a different directory path to save the file in.

create tablespace "VOLUMT" datafile 'VOLUMT1.dbf' size 250M autoextend on;

please check and tell me if it worked fine.

Answer 2

all the guys..

First of all, really appreciate to you all for replying...

When I input the follwing

select   file_name,
         file_id,
         tablespace_name,
         status,online_status 
from     dba_data_files 
order by tablespace_name;

The output is

FILE_NAME
--------------------------------------------------------------------------------
   FILE_ID TABLESPACE STATUS    ONLINE_
---------- ---------- --------- -------
/home/oracle/db/oradata/ORAC12/ID/sysaux01.dbf
    28 SYSAUX     AVAILABLE ONLINE

/home/oracle/db/oradata/ORAC12/ID/system01.dbf
    27 SYSTEM     AVAILABLE SYSTEM

/home/oracle/db/oradata/ORAC12/ID/ID_user01.dbf
    29 USERS      AVAILABLE ONLINE

There is no such as "VOLUMT" tablespace. When I re-try to create a "TEST01" tablespace, eventhough it's already deleted, it shows 'the file exists already'..

When I get into the directory, there are other SID's as well. And, one of them has "VOLUMT". However, they are different "SID" so they can have same name of tablespace, isn't it?

Answer 3

The error you get indicates that there is an existing data file with the same name specified VOLUMT.dbf.

Check if there is an existing file with the same name.

SELECT FILE_NAME, TABLESPACE_NAME FROM DBA_DATA_FILES WHERE LOWER(FILE_NAME) LIKE '%volumt.dbf';

To find the data file path for TEST01 you can easily query it through the following statement

SELECT FILE_NAME, TABLESPACE_NAME FROM DBA_DATA_FILES WHERE TABLESPACE_NAME LIKE 'TEST01';

Answer 4

You are only looking at the tablespaces and not at the database files. Try querying the dba_data_files Data Dictionary View.

Here an example command:

set pages 50
set lines 230
column file_name format a60

select file_name, file_id, tablespace_name, status,online_status 
from dba_data_files order by tablespace_name;

This should list all the database files and show you to which tablespace they belong.

In response to your comment:

You might have to switch the SID and run the query for each SID in order to determine which database files names have already been used.

You can't have the same database file (name) for a different SID and a different tablespace in the same directory.

Possible Solutions

1. You will either have to delete the database file VOLUMT.dbf from the tablespace it is currently attached to, to be able to re-create the tablespace VOLUMT with the `VOLUMT.dbf database file.

2. You will have to create the tablespace VOLUMTusing the database file VOLUMT.dbf in a different directory.

Your issue isn't the tablespace VOLUMT, but the database file VOLUMT.dbf that already exists for a different SID and a different tablespace.

Answer 5

delete the offending tablespace and it's contents. use

DROP TABLESPACE 'the tablespace name' INCLUDING CONTENTS;

for your case;

DROP TABLESPACE VOLUMT INCLUDING CONTENTS;
