Thank you guys for your answers.
>> I could understand if you think that tx 2 is still active, but why do you >> think >>that tx 3, tx 4 ... tx 491 is also active ??? What make you think so ? The program which I use for analyzing gstat outputfile says so. But of course you are right, this is confusing. OAT = 2, Next transaction = 492 but that does not necessarily mean that there are 490 active transactions. After all transaction 3, 4, 5, 6...N might by already finished. Here is the screenshot from the program: http://pl.tinypic.com/r/20z8t21/8 http://pl.tinypic.com/r/20z8t21/8 Regards.
