I need a database transaction generator so I can test some concurrency control schemes (e.g. 2-phase locking, etc.). I could use any one of the following: 1. a program that produces transaction sequences 2. the output of such a program 3. some recorded transactions from real database systems Of course, the more data the merrier... I'm looking for something with a simple format, but with realistic access patterns and distributions. Example format: Begin Transaction 1, R(a), R(b), W(b), ..... , Commit Begin Transaction 2, R(c), W(b), W(a), ..... , Commit . . . Note, I need the transactions themselves, NOT the schedule resulting from concurrent execution of the transactions. Although If I can extract the transactions from a schedule, I could use it. Any information or pointers to information would be appreciated. Thanks, Alex Tomlinson -> alext@ccwf.cc
