DELETING THE DATA FROM THE TABLES IS NEVER A MEANINGFUL SOLUTION COZ DATA IN SOME TABLES SHOULD BE RETAINED FOR A LONGER PERIOD.
THE ALTERNATE SOLUTION WOULD TO ENABLE THE TABLESPACES TO AUTOEXTEND, USE THE BELOW COMMAND TO EXTEND ALL THE DMS TABLESPACES TO AUTOEXTEND.
db2 -tx "select 'alter tablespace '||TBSPACE||' autoresize yes increasesize 500m maxsize none;' from syscat.tablespaces where TBSPACETYPE='D'"> autoextend.sql
Whenever a particular tablespace get full, automatically the Tablespace gets increased.
The value 500M is the size we increase in our DB's, kindly set the size based on your requirement.
