How to efficiently remove all rows from a table in DB2

Question

I have a table that has something like half a million rows and I'd like to remove all rows.

If I do simple delete from tbl, the transaction log fills up. I don't care about transactions this case, I do not want to rollback in any case. I could delete rows in many transactions, but are there any better ways to this?

How to efficiently remove all rows from a table in DB2? Can I disable the transactions for this command somehow or is there special commands to do this (like truncate in MySQL)?

After I have deleted the rows, I will repopulate the database with similar amount of new data.

Answer 1

It seems that following command works in newer versions of DB2.

TRUNCATE TABLE someschema.sometable IMMEDIATE  

Answer 2

To truncate a table in DB2, simply write:

alter table schema.table_name activate not logged initially with empty table

From what I was able to read, this will delete the table content without doing any kind of logging which will go much easier on your server's I/O.
