Question

I tried to generate some test data by running the following sql.

BEGIN    
  FOR i IN 1..8180 LOOP
    insert into SPEEDTEST
    select \'column1\', \'column         


        

Answer 1

To resolve this error:

ORA-01653 unable to extend table by 1024 in tablespace your-tablespace-name

Just run this PL/SQL command for extended tablespace size automatically on-demand:

alter database datafile '.dbf' autoextend on maxsize unlimited;

I get this error in import big dump file, just run this command without stopping import routine or restarting the database.

Note: each data file has a limit of 32GB of size if you need more than 32GB you should add a new data file to your existing tablespace.
