These flags are used for SPECjAppServer results 20071107-00092 and
20071107-00095 for the Sun Java Systems Application Server 9.1 Update Release 1

1) DATABASE LOGGING FLAGS
-Dcom.sun.jts.dblogging.insertquery=insert into txn_log_table_0 values ( ? , ? , ? )
-Dcom.sun.jts.dblogging.deletequery=delete from txn_log_table_0 where localtid = ? and servername = ?

These flags identify the database tables and SQL used for transaction logging.
For details of how transaction logging works in general, please see
http://docs.sun.com/app/docs/doc/819-3672/6n5sj2t39?a=view

2) CMP PRE-FETCHING FLAGS
-Dcom.sun.jdo.spi.persistence.support.sqlstore.MULTILEVEL_PREFETCH=true

This flag allows relationship-prefetching for CMP 2.1 Entity Beans to
occur over multiple levels (so that if a is releated to b and b is
related to c, the flag means you can retrieve a, b, and c in the same
query; by default we would retrieve only a and b or b and c depending
which entity is accessed).
