Flash back database in RAC

HI, I have a question regarding using the flash back database feature nwhen in a rac environemt...I see in the documentation that when flashing back the database that you will need to us the open database with the resetlogs option in order to flashback. So does the open database resetlogs need to be done for each instance in order to get the instance database open?
Thanks.

See if MOS Doc 819905.1 (How to Enable Flashback for a RAC Database on ASM) helps.
Also MOS Doc 416496.1 (ENABLE FLASHBACK DATABASE IN RAC ENVIRONMENT).

Can i recovered dropped users from Flash Back Database

I am having confusion on step by step process for Recovering dropped user from Flash Back Database or from RMAN.
And Which case we will use Flash Back Database or RMAN?

1) Restore database (PITR- Point In Time Recovery) until the schema was dropped.
RECOVER DATABASE UNTIL SCN XXXXX;
2) If you only want a table:
flashback table XXXX to before drop;
3) Flashback database (if you have flashback on):
FLASHBACK DATABASE TO SCN XXXXX;
or
FLASHBACK DATABASE TO TIME "TO_DATE('XX/XX/XX','MM/DD/YY')";
You have some examples at documentation:

ORA-01033 and flash back database

I don't really know how the flashback database work. I enabled the backup recovery option during the 11g R2 installation. It will automatic scheduled the backup around 2:00AM daily. My question is does it automatically restart the database after the backup? Because I got an error ORA-01033 from the EM alert email every day around the same time.
Thanks for any help!

Can anyone help me? I'm still getting this alert every morning around 2AM:
Target Name=MEDIAMGR
Target Type=Database Instance
Host=mediamgr2-db
Metric=Status

Message=Failed to connect to database instance: ORA-01033: ORACLE initialization or shutdown in progress (DBD ERROR: OCISessionBegin).
Notification Rule Name=Database Availability and Critical States

This may not related to the flashback backup job , but it did happen when the backup job was running. Also, another application server crashed at the same time when this happened. If I turn off the application server before 2AM, I don't get any error or alert. My question is how do I find out what cause the database to crash? Beside the alert log, is there another log that has the crashing information? How do I troubleshoot the problem? Can that be a memory issue?
Here is the error message from the app server:

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.

Duplicate Target database for RAC

Oracle Database 11g Enterprise Edition
Red Hat Linux
Hi
I am cloning a RAC database using Duplicate Target Database command. First we need to create one Auxiliary Instance using the init file of RAC source database.
I see the following in the init file,
MDB1.undo_tablespace='UNDOTBS1'
MDB2.undo_tablespace='UNDOTBS2'
What should I specify in the init file of Auxiliary instance for these Undo tablespaces ? I am setting CLUSTER_DATABASE to FALSE since the Duplicate database is a single instance one. Only the Source database is RAC.
I am cloning only SYSTEM, SYSAUX, One User tablespace and the Two Undo tablespaces for a point in time 14 days back. I am skipping all other tablespaces.

Hi Morgan,
Is this correct to specify in the Init file ?
*.undo_tablespace='UNDOTBS1'
here UNDOTBS1 is already UNDO tablespace of one instance as I already mentioned.

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

How can I flash back off on UNDO tablespace?

I have used flashback on ( oracle database), then I have flashed back off some tablespaces.
I have some question:
Can I flashback off on UNDO tablespace?

Thank you.

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.
Read this link, it saves me the time of going into detail http://www.computerclub.org/tips_tricks/tip_performance2.htm

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.

Related to recovery in Physical standby database in RAC

In Physical Standby database all instance involved in recovery processes or any one instance will be their in in recovery mode
If is like this another instance will be for high availabily can any one in forum explain me it will be help full

With your Primary database being RAC, the Physical Standby does not have to be RAC, although, obviously it would be preferred to have scalability as required at a DR site.
Whether your Standby is RAC or non-RAC, the automatic Recovery that is done at the Standby is done by one instance only. It would be applying the ArchiveLogs from all the threads (i.e. instances) of the Primary.
Database Recovery is always done by a single instance.

Flash Lite database application - help!

Dear all,
I would like to ask for your help/opinion.
I am a beginner Flash programmer. I am planning to create a Flash Lite application that will provide information on current cultural events (e.g. music, theatre), cinema listings, restaurant recommendations etc.
For this, I need to have a database on my server, which will store all the data (e.g for a music event I need the place, artist name, date and time, description of event, contact details, and maybe an image).
I then want to transfer the data (only updates) to my users' mobile phones, and store them there. This will allow them to update and then be able to browse the information offline.
I am not sure how to do this. I read about Shared Objects, but it seems that these objects do not provide enough space for what I need to do (let's say 1000 records at least at any one time).
Can anyone provide any direction on how to solve this problem? Just to recap, I am looking for a solution to create a Flash Lite database application that will receive cumulative updates from a web server and store the data locally on the mobile.
Thanks in advance for any kind of help you can give me!
Andreas

To handle the synchronization of these items you will need to use plugins, which will restrict your platform reach.
These are two great starting points:
KuneriLite
Nokia Platform Services
Using the solutions above you can download and upload files, and using XML you can load and sync events. Unfortunately it would be quite complex to handle the delta between items, updates and such so I recommend using a dynamic XML feed.
Good Luck!

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 ).
