Reg : flash back query set up

This is regarding the flashback feature which is available in Oracle 10g.
Using this feature we can get the tables which are dropped.
Note:-
Table data cannot be recovered if we use truncate table command as it does not uses a undo segment and just changes the pointer in the memory to an empty location.
To recover a table that's sitting in the recycle bin, you can use the
command:
flashback table table_name to before drop rename to new_table_name;
Information about dropped tables in the recycle bin is stored in the new table:
user_recyclebin.
But I'm not able to find the same in Dev.
What are the parameters/ steps required to set up the same.

Hi,
Please have a look on the following link:

Please tell me about flash back query

Hi
Please tell me about flash back query and when to use it and the advantages..
Thanks in advance..

Flash back query is mainly used for table recovery and data recovery.. To do the flashback user requires the FLASHBACK ANY TABLE privilege.
This is how it can be used.
1) DROP TABLE emp;
2) SELECT * FROM recyclebin
You will get the tablename in the Recyclebin table.
3) FLASHBACK TABLE emp TO BEFORE DROP.
Following part expalins how it cane be used for the data in the table.
1) UPDATE emp SET sal=5000;
2) COMMIT;
3) ALTER TABLE emp ENABLE ROW MOVEMENT;
4) FLASHBACK TABLE emp TO TIMESTAMP(SYSTIMESTAMP-5/1440);
Now query the table to get the data which was updated before 5min.
Similarly one can use it for the database recovery also.

Flash back query !!

Flash back query ( any of the given options) is it possible to recover truncated table data?
Whether it has to be database point in time recovery or there are other ways to do it ?
Examples will be of great help.
TIA

here it goes
SQL> select * from t; TID I---------- - 1 A 1 B 1 D 2 A 2 C 2 C 2 B 3 A 3 C 4 A 4 B 4 C 5 A 6 A 7 A 15 rows selected.

Moreover, the answer is described in the documentation:
http://download-uk.oracle.com/docs/cd/B19306_01/server.102/b14220/consist.htm#sthref2174
Flashback Query does not work through DDL operations that modify columns, or drop or truncate tables

How many transactions can we retrieve from flash back query in oracle9iR2?

For Example....
user1 deletes some records in the table1 at 10:30am
user2 adds some records in the table1 at 10:40am
user3 updates some records in the table1 at 11:00am
i have set the undo-retention parameter for 5 days.....
so can i retrieve all the transactions made from 10:30 to 11:00am?
or i will get only the last transaction at 11:00am?
also, how can i know the user1 deletes some records at a particular time?
how can i know the sql executed time?
I am using oracle9iR2
Thanks
sathyguy

> For Example....
I am going to set it for 3 or 4 hours.....not for 5 days...thats why i mentioned it as "for example" now im going to test this scenario in my r&d server.....with less undo_retention.
so....to find the transaction details (deleted or updated or etc....) i have to set up auditing or logminer...ok.....again the same doubt......
for example this is the case....
1. i set up the undo_retention=2 hours
2. i have the undo tablespace size as 3gb
3. i have set up the logminer to know the transaction details
will the undo tablespace will store all the deleted,updated records and tables for 2 hours?

SCN USAGE IN Flash back query - Help needed - Urgent

Hi,
I am using the query by using the timestamp value to get the particular version of the data.
How to use the SCN value in the flashback query and what is the query used for getting SCN value for todays changes.
How to check what are all the scn are available for the particular table?
I am using the query as
select a.eno,
b.eno,
a.ename newname,
b.ename oldname
from emp a, emp as of timestamp
to_timestamp('08-NOV-2006 06:32:21.999999 AM','DD-MON-RRRR HH:MI:SS.ff6 AM')+2000/1162970290000 b
where a.eno=b.eno
How to use the SCN instead of time stamp for getting the SCN value for the table emp for todays changes.
Please suggest..
Thanks in advance.

That might be difficult. Check out the Flashback Query Restrictions from the Oracle9i Application Developer's Guide. In particular, the third bullet. It would seem that SCNs are recorded every 5 minutes for flashback use. If your changes occurred during a five minute window, you may not be able to get both values.

Flash UI Components Set 2

Hi all - anyone knows where to find the
Flash UI Components Set 2
This should be in the exhange section ...... but its only
ver.1.4
in the Flash UI Components Set 2 there is a rich text editor
that i want to use
Any Idears where to find it ?
Flemmnig

Just for future reference for anyone with a similar problem..
I figured out the issue was that my wmode was set to transparent
windowless. When using a transparent background for a flash movie,
Flash UI components do not show up. I'm not sure if this is a bug
or not... when I set my wmode back to "window" they came up
fine.

That I never heard before.
A good tip if you have a running system

How can we use flash back querry

Hi ,
How do we use the flash back querry.
Govardhan

For enabling the Flashback, we need to set this below
in init.ora file.
UNDO_MANAGEMENT = AUTO
UNDO_RETENTION = 1800
declare
cursor c1 is select * from emp;
emprec c1%rowtype;
begin
dbms_flashback.enable_at_time('01-JUL-05:11:00:00');
OPEN C1;
DBMS_FLASHBACK.DISABLE;
LOOP
FETCH c1 into emprec;
exit when c1%notfound;
insert into emp(
EMPNO,
ENAME ,
JOB ,
MGR ,
HIREDATE ,
SAL ,
COMM ,
DEPTNO)
values(emprec.empno,
emprec.ename,
emprec.job,
emprec.mgr,
emprec.hiredate,
emprec.sal,
emprec.comm,
emprec.deptno);
end loop;
close c1;
commit;
end;

My cursor recently started to dissapear when im not using it but when i press a key it flashes back for a second... how do i fix this?

Well I'm a frequent Firefox user ad recently my cursor has started to dissapear when I'm not moving it. However when i press a key it flashes back for a second also, when I'm moving it flickers a lot (one moment its there one moment it isn't). How do i fix this?
== This happened ==
Every time Firefox opened
== Earlier today (july 20th 2010)

Never saw this problem until today, first on Facebook, then on these Mozilla support pages. I had one Firefox window with multiple FB and Mozilla tabs open.
Here's my observations: On the FB and Mozilla pages, the cursor (arrow/hand) acted identical and as described here, would disappear after 2-3 seconds of inactivity or non-motion, then instantly reappear with mouse movement or key strike but only momentarily if no further motion/action occurred. Interestingly, I also had one FoxNews tab (actually FoxNewsInsider) open, and observed slightly different activity. The Cursor/hand would disappear as described above, but instead of staying invisible, it flashed on /off for what appeared to be <1 second on then <1 second off, until mouse movement or key strike. Now, here's the really interesting part ... When I opened a second FoxNewsInsider tab, the problem corrected itself with no direct action on my part to resolve the issue. I was going to close all tabs, then Firefox and perform the system reboot to correct this annoyance ... but, still have not seen the problem.
Okay, I'm not going to say viewing FoxNewsInsider webpages not only provides one perspective on news, and the added benefit of fixing cursor/hand problems .. but maybe there's some to being well informed ... Sorry folks, couldn't resist ... :) I will be watching for the disappearing cursor issue again, and will reply here with any updates or changes in my observations.

Looking for MSI FX5900 TD128 BIOS !! Need to flash back from 5950

I had flashed my BIOS a couple of months back using the WFFLash utility of Leadtek and since then ive been gettin low scores on 3dmark03!
Overclocking my 5900 once get me to get a 6300 3dmark03 score and now it doesnt go over 5800 or even less!!
I was hoping if some1 could either give me a link or if some1 had the BIOS of the GPU i own, it was be grateful!!
Even has any1 else encountered this low scores after their Flash!
Oh yeah which utility do i need to re-flash - WFFLASH or NvFlash!
Hope to find some help here ! !
THanksss !!

Utk,
The BIOS is static and flashing back probably won't make things better. I believe your scores or performance is suffering from OS decay. It might be a good idea to review all the software you have installed since you flashed your BIOS and see what's running in the backround. Perhaps even a fresh install of the drivers, maybe even a fresh install of the OS.

Looking for performance degradation
Before I move on, let me point out that there's another area where benchmarking software really shines for computer users and that is in keeping an eye out for performance degradation due to OS (Operating System) Decay.
This type of problem is little understood but very common. Let's take a closer look. As you've been using your existing operating system over time, you've probably installed, upgraded, and uninstalled numerous applications. In addition, you've probably added and removed lots of hardware and device drivers. Furthermore, you may have upgraded your operating system with a multitude of patches, bug fixes, and updates.
Considering all the wear and tear these types of operations put on your operating system, chances are good that you've experienced OS decay first hand. Some of the symptoms of OS decay are frequent system lockups or crashes, strange error messages, unusually slow performance, and Windows directory that's bloated with files.
Of course you must realize that OS decay is actually a natural occurrence that results from the heavy use of your system. You could look at the OS decay problem much as you would look at an aging automobile—no matter how well you take care of it, eventually you're going to have to buy a new one.
Fortunately, you don't have to buy a new computer to solve the OS decay problem; you just have to rebuild the operating system from scratch.
As such, the question is not if you must rebuild, but when you must rebuild. If you regularly check your computer and keep tabs on your system's progress over time, you'll have a much better picture of when the OS decay has gotten so bad that it's degrading the overall performance of your system.

S110: what purpose does the Flash white balance setting serve?

I assume if you're using the flash for a shot then the camera knows it, so why would you have to set it in the WB menu. If you don't need to set it, what's it for? When I shoot with flash and WB set to Auto, everything comes out fine (except when zooming; see a separate post ont hat nearby). Thanks.
Solved!
Go to Solution.

If you are shooting underexposed in order to kill all the ambient light, leaving only the flash light to show in the picture, then you need this. On AUTO WB the camera would have still been thinking the background/ambient light color is relevant so it would give you a bad color.
That is something "strobists" in particular do a lot.

Since IOS 7.0.3 Screen flashes back to main screen for no reason

If I am reading an email or a web page, the screen usually flashes back to the main screen without reason or notice. I have "reset all settings" in the settings section, perform cold and warm reboots but nothing seems to help. Any others with similar problem?

Try resetting the device (hold the home and power keys down until the Apple logo appears ).
