the error is unrelated to the SET TRANSACTION statement. the error simply means that Oracle is not able to provide a read-consistent image of the data you access in the script, probably caused by *other* transactions simultaneously running on the same database, making changes to the database, and committing those changes. Those *other* transactions are apparently using rollback segment RBS02, and apparently that rollback segment is quite small -- so it gets overwritten in a cyclic way. You probably have a heavy, long-running query in your script? hope this helps, kind regards,

Hi all, I have got one problem. I am running a script in which my first statement is " SET TRANSACTION USE ROLLBACK SEGMENT RBS01;" but the script is throwing error as " ora-01555 (See ora-01555.ora-code.com): snapshot too old. Rollback segment rbs02 too small" . Now the problem is why its throwing error on RBS02 when I have set my transaction to use RBS01? Any comments on this or any suggestion ?
