I am executing a series of sql statements using a JDBC connection on a DB2 server. On the last execute() of the simple sql: DELETE FROM MYTABLE, the thread gets hung for a long period of time even if the table somply contains a single record.

The application server I am using is WAS. I wonder if this is an issue specific to WAS and DB2 combination as the same code works on other environments.

Does anybody have any idea what is going on here?

    Have you issue the command directly from the CLP? It could be other problem such as:

    • Transaction log problem: There are a lot of rows to delete, and this takes time. Also, the transaction logs have reached the limit, and the database does not do a rollback but waits for empty log freed by other transactions.
    • Lock problem (concurrency): some of the rows your are trying to delete have locks in other transactions, and the applications has to wait to release them (lock wait)

    Also, try to do frequent commits.
