ORA-60019: Creating initial extent of size 14 in tablespace of extent size 8

The minimum extent size of the tablespace must be 1M when db_securefile is set to always. If the extent size is less than 1M the error ORA-60019 is reported.

1.precreate the tablespaces with a uniform extent size of 1M

SQL> CREATE TABLESPACE TEST DATAFILE '/oracle/oradata/test.dbf' SIZE 500M EXTENT MANAGEMENT LOCAL UNIFORM SIZE 1030K SEGMENT SPACE MANAGEMENT AUTO ;

or

2. Create the tablespace with default local extent management:

     SQL> CREATE TABLESPACE TEST DATAFILE '/oracle/oradata/test.dbf' SIZE 500M EXTENT MANAGEMENT LOCAL SEGMENT SPACE MANAGEMENT AUTO ;

the above solution for Version 10.2.0.1 to 11.2.0.3 

In 12c :

alter system set db_securefile=NEVER  scope=both;
