Hi I'm writing concurrency tests for a data insertion web service.
The database table has a unique key field (it cannot be autoincremented :-( ) so I'm trying to get JMeter to generate unique keys for me. I need to: 1) Have a starting vlue that is globally shared between all the threads 2) Have each thread increment its value between insert statements 3) Save the final value to a file so that the next test run can use it. Of course, this leads to difficulties with managing thread concurrency. Additionally, the database key field is an alph-numeric with a maximum of 6 characters, so I don't have a vast range of values to play with... Can this be done with JMeter? -- Andy
