ORA-01658: unable to create INITIAL extent for segment in tablespace TS_DATA

问题

When i tried to create a table in my User_DB schema i am getting an error as ORA-01658: unable to create INITIAL extent for segment in tablespace TS_DATA. I run the following query to get all the TABLESPACE_NAME:

SELECT * FROM DBA_DATA_FILES;

But i really dont know which tablespace i am using and how to extend the tablespace to solve this issue.

回答1:

As the error message indicates, you're using the TS_DATA tablespace. You can extend it by either enlarging one of the existing data files:

ALTER DATABASE 
DATAFILE 'C:\ORACLEXE\APP\ORACLE\ORADATA\XE\TS_DATA.DBF' 
RESIZE 3000M;

Or by adding a second datafile to the tablespace:

ALTER TABLESPACE ts_data 
ADD DATAFILE 'C:\ORACLEXE\APP\ORACLE\ORADATA\XE\TS_DATA2.DBF' 
SIZE 1000M;

Or just allow the datafile to auto extend:

ALTER DATABASE 
DATAFILE 'C:\ORACLEXE\APP\ORACLE\ORADATA\XE\TS_DATA2.DBF'
AUTOEXTEND ON
MAXSIZE UNLIMITED; -- Or some reasonable cap

回答2:

ALTER DATABASE DATAFILE 'C:\ORACLEXE\APP\ORACLE\ORADATA\XE\TS_DATA.DBF' RESIZE 3000M;

This worked for me thanks
