A bug of Streams in Oracle 9.2.0.1 for windows-32bit platform ?

Question

I made a stream on Oracle 9.2.0.1 .As you know,two SCN ,Applied_SCN and Captured_SCN ,can told some information about capture process.If you use stream ,you have to run database under archivelog mode.
Some days later,about 2G redo logfiles produced.If you do not delete them ,one day they can filled in your store space ,which make the stream not work .
But before you delete these redo log files,you must make sure the SCN of range of redo log files you want to delete.If delete without check,capture process relys on these files and will be aborted.Before I had this experience . But if you do not made operations to database tables,and no changes need to transmit.Beacause applied_SCN only increase after receiving messages from remote database.So when I let alone my source database,I find applied_SCN keeping the same and redo log file almost be full of restore space.Others told that Oracle 9.2.0.1 has some bugs .But I can not get Oralce 9.2.0.x for win-32 for testing.
What advices can you give? Thank you.

Well, heres my test (10g, for I dont have a 9.2.0.1.0, but I think it´d show the same result):
Connected to:
Oracle Database 10g Enterprise Edition Release 10.1.0.4.0 - 64bit Production
With the Partitioning, OLAP and Data Mining options

But he is getting output of table T2 too se his last postI don´t think so, because he didn´t SELECT it. Would be nice to just copy & paste the output...
