Bug in 9.2.0.4
Hi Listers Any idea about this Bug in 9.2.0.4. If you try "select 'Hello' from dual order by 1 desc;" you may run into the bug. It creates a dump in udump and could disconnect your session. Oracle is creating a one-off patch to fix. The bug is for any order by x, where x is a number, desc and the column is a constant. It does not happen on my instance. Any Details will be appreciated.

RE: Redo Logs Problem
Redo is not effected by database
configuration but by database activity.
Has the no. of transactions increased
significantly?
If the activity is the same,a wild
guess -Has someone issued a command "ALTER TABLESPACE name BEGIN
BACKUP" and forgot to issue the command "ALTER TABLESPACE name END
BACKUP"???
You can check that using the view

RE: Transparent database objects after merging
I think I understand ur problem. What u can do is Create New Users for both types of form users and create private synonymsin both user schema for the respective tables and grant relevant permissions. For e.g for Customers_A table in User_A schema create private synonym with the Name Customer.

IN operator statement time = 3sec and the Exists operator statement time = 12 sec. After analysis I have come to know that theEXISTS statement is causing more logical block reads that IN statement, approx 4 times and hence the delay.

Need to Log on 2000 users
Hi Gurus, I am facing a problem. I need to log on 2000 users to my database via dedicated server connection on Oracle 9iR2 running on Windows 2000 Advanced server. Please guide me as to what all parameters need to be tuned to achieve the same. The Server is a single CPU server with 3G RAM. I need just to logon 2000 users. This is a load test that I need to perform. Thanks to all Regards Munish Bajaj Blank Bkgrd.gif
