Hi @johnw66 ,

Have you tried adding a new datafile for the existing tablespace?

ALTER TABLESPACE IFSAPP_DATA ADD DATAFILE '/u01/oradata/userdata03.dbf' SIZE 200M;

To find out the location and size of your data files:

SELECT FILE_NAME, BYTES FROM DBA_DATA_FILES WHERE TABLESPACE_NAME = 'IFSAPP_DATA';

Hope this helps! 

@johnw66 Please note that It would be better to fix this as soon as possible as it could eventually lead to a System Down situation. Pls refer to Alter Tablespace Add Datafile:http://www.dba-oracle.com/t_alter_tablespace_add_datafile.htm

@Himasha Kapugeekiyanage Thank you very much, that resolved the issue.

@RanukaSerasinghe  Thank you for your input as well.

Have a nice day.

I have had the same error relating to a separate custom event.  

I have added another datafile, but am wondering why this is happening now?

ALTER TABLESPACE IFSAPP_DATA ADD DATAFILE ‘F:\oradata\IFSLCDB\IFSLPDB\IFSAPP_DATA04.dbf' SIZE 200M;

I am having a look at the SERVER_LOG_TAB to see what is eating the space.

Thanks  John
