    Cool Unanswered: How to know who deleted the rows and what sql was used ?

    OS390, DB2 Ver 7

    We suddenly found a large number of rows missing in one of our tables. Is there a way to find who did what and how ? We dont have any third party tools to help. Any suggestions or steps to find this info is highly appreciated.

    There are tools to read the logs, but they cost money. BMC is one vendor that provides one.

    You can do that only with DB2 core utilities. First, you have to run a report recovery against the table in question. There you will get a listing about UR with a time, when this UR was created and STARTRBA and STOPRBA. With these values you can run the DSN1LOGP-utility to get the records from the log (this can be a huge amount of data). In these log datasets you will find records like 'DELETE IN A PAGE' with a userid displayed. It is a little bit cumbersome, but I did it some times with success.
