Subject How to execute DDL and DML statements concurrently?
Date Thu, 19 Apr 2007 20:20:33 GMT
Recently my colleague has run some benchmark tests on Derby.

During the test we execute DDL and DML statements concurrently,

We find that Derby will lock the data dictionary for a relative long time
when executes DDL statements, 

and then the DML statements would not be executed and finally timed out.

Are there some way that we can work around this so that DDL and DML
statements can be executed concurrently?


Any help would be appreciated.
