Trying to enable flashback database on 11g Linux platform database

Hello,
SQL> ALTER DATABASE FLASHBACK ON;
ALTER DATABASE FLASHBACK ON
ERROR at line 1:
ORA-38759: Database must be mounted by only one instance and not open
Can any one help understand why I am getting this error while I have only one instance open?
Thanks
Alain

As Hemant asked, what's the status of the db, is it mounted or open? Issue,
select status from V$instance This would show the status to you. If it's open , you must bring it to the mount stage with a clean shutdown and then retry.

A new question on how to Enable Flashback Database on the standby database?

Best Practice document said:
Enable Flashback Database on the standby database to minimize downtime for logical corruptions.
I would like to know where to find document or anybody already had experience for this topic?
Also I would like to know what is the best practice for backup/recovery of the Physcial standby database?
Thanks in advance.

Hello;
Just an opinion but I like the book "Oracle Data Guard 11g Handbook" as both the document and the answers to the second question.
Chapter 12 covers the A to Z of RMAN with Data Guard.
This book sold me on Flashback since Flashback allows a former Primary database to be reinstated after a failover operation with being restored ( provided sufficient flashback logs are available)
My own experience is I tried a failover test without it and trash my test Primary.
I did a simple failover test a few weeks ago, here are my notes.

Enable flashback database

Could anyone explain me what is archive mode, and how to do it?
I tried to enable the Flashback Database in oracle 10g, or maybe you all can guide me how to enable flashback oracle.

guess this link is for 11g. still there shouldnt be any change in the procedure i guess.No that's deliberately given for 11g as OP didn't mention any db version in the first line. For 2nd line, because 10g was mentioned that's why I gave 10g specific doc. You are correct though that the procedure is exactly same for both 10/11g to put a database in archivelog and in general as well that what is Archive log mode.

Using Flashback Database on 11g

hi everyone,
My 11g db is size 50 GB on a very strong Windows server.
No performance problems whatsoever.
If I enable Flashback Database logging am I likely to notice any performance degradation? The data is not really heaviily changed.
What about disk space - does it use the existing redo/archive logs or does it create different logs for the flashback feature?
Thanks for your opinions.

If I enable Flashback Database logging am I likely to notice any performance degradation? The data is not really heaviily changed.Even if the data is not heavily changed, with the internal changes happening, there would be some activity always generating Redo/Undo. You would want to check the working of the RVWR process to see any possible waits over it. In addition to this, if the speed of the writing of RVWR is not good enough to write, you would see the contention on the Undo tablespace as it won't be freed as long as the corresponding writes are not saved by RVWR.

FLasback database does not uses the existing redo logs. Yes, it does uses the archived logs in addition to the FLB logs. So before you think to use this featuture, you do want to check the retention period of the logs , also the disk space required to manage that much retention period.

Cannot enable flashback database??

I am using 10gR2 10.2.0.1
Under EM Home: it shows under " High Availability ":
Last Backup Apr 14, 2007 8:03:33 PM
Usable Flash Recovery Area (%) 92.35
Flashback Logging Disabled
When I get to the "recovery settings", I have make sure I have turned on Archivelogmode, however, the "enable flashback database" section was missing.
What's wrong about my database settings?
I have tried to explicitly do the standard code and have got the following errors:
SQL> SHUTDOWN IMMEDIATE;

Why Database should be in mount stage for enable Flashback

Oracle 11.1.0.6.0
Windows
Why database should be in mount stage for enabling flashback feature but we can disable this feature even in Open mode?
Kindly share your inputs .
Thanks,
Alok

>
As per doc this is prerequisites that database should be in mount mode to enable flashback but we can disable flashback even in open mode.
I would like to know the concept behind this.
>
Only Oracle knows why and why, for 11g, you can now have the database open. Any 'guesses' would only be guesses.
You can get some possible clues from the DBA guide section for 10g 'Starting Up and Shutting Down' the database.
http://docs.oracle.com/cd/B19306_01/server.102/b14231/start.htm
Traditionally MOUNT mode (database closed) is used for administrative activities by the DBA that need to be done either when there is no user activity that might conflict with them.
>
Starting Up an Instance
•Start the instance and mount the database, but leave it closed. This state allows for certain DBA activities, but does not allow general access to the database.
>
Or this from the same doc a little later on
>
Starting an Instance and Mounting a Database
You can start an instance and mount a database without opening it, allowing you to perform specific maintenance operations. For example, the database must be mounted but not open during the following tasks:
•Enabling and disabling redo log archiving options. For more information, please refer to Chapter 7, "Managing Archived Redo Logs".
•Performing full database recovery. For more information, please refer to Oracle Database Backup and Recovery Basics
The following command starts an instance and mounts the database, but leaves the database closed:
STARTUP MOUNT
>
Perhaps part of the flashback enable process required exclusive access to ALL tablespaces or datafiles; meaning you can't have users modifying them.
Perhaps the enable process for 10g needed to perform simultaneous updates to all datafile headers, the controlfiles and undo or cache or data dictionary entries; meaning you can't have users getting in the way.
Dont' know.

Hello;
Script has to be run from auxiliary.
Great details, but what I don't see is how you connect in RMAN.
Example
Start RMAN

connected to auxiliary database: RECLONE (not mounted)Nothing in your tnsnames or listener jumps out as wrong. I copied them into my text editor and compared against my working ones.
Generally for active duplication I start the future standby on a pfile NOMOUNT.
Auxiliary Instance Initialization Parameters Needed :
DB_NAME
CONTROL_FILES
DB_BLOCK_SIZE
( add extra parameters like DB_FILE_NAME_CONVERT and LOG_FILE_NAME_CONVERT instead of using the SET command - clean up standby spfile right after duplication )
Then start RMAN and finally run a single line duplication command.

How to manage oracle 9i databases from 11g ?

Is there any option similar to 9i OEM's "Add Database to tree" in 11g ?
currently I monitor 30 databases, all running 9iR2, using enterprise manager console. I had removed Oracle 9i from my system to install 11g, so is there anyway to monitor 9i database from 11g or do I have to re-install 9i into a new home ?
My system is Windows XP and most databases are on linux.

What, precisely, do you mean by "11g Enterprise manager console"? Are you talking about a web-based interface? Or a Java-based console application?
If you have not done a separate OEM install, you're most likely using the database control, as web-based interface that allows you to manage a single database. You would need to install the Grid Control in order to manage multiple databases through the same interface.
You're probably right, that's why I asked the question. Perhaps the original poster meant the "10g Enterprise Manager console". Perhaps he meant the "11g Enterprise Manager Database Control". Perhaps he meant the "11g Enterprise Manager Grid Control". Or perhaps he meant something different (i.e. SQL Developer is a console application that ships with 11g and has a variety of reporting scripts).
The OP for the 11g installation could not have possibly made a separate OEM install, OEM is not included in 11g any more and he has not mentioned trying such intall. The OP was clear enough, so IMO there is no confusion, 30 9i databases, 1 11g database. There was not a 10g in between. I would not go so far as to say an 11g grid control, since there is no such grid control, the latest version for grid control is 10.2.0.4.0 for R2 and 10.1.0.3.0 for R1. And SQLDeveloper, yes, it is a java application included with 11g, and you can launch scripts from there, but in no way it is a managing environment the way the OP pretends.

According to

A workaround is to upgrade it on the same platform and then move it to the new oS and change wordisize.

Enable display through Putty on Linux

Hi All,
I need am trying to enable the Xmanger windows through putty in my Linux box, I have tried different options but still I am not able to get the display through putty
Here is what I have done:
export DISPLAY=:0.0
[oracle@yblpvdakgrid ~]$ xhost +
Xlib: connection to ":0.0" refused by server
xhost: unable to open display ":0.0"
AND
[oracle@yblpvdakgrid ~]$ export DISPLAY=10.0.x.x:0.0
[oracle@yblpvdakgrid ~]$ xhost +
xhost: unable to open display "10.0.x.x:0.0"
Regards,

Hi,
Try undesrant what mean each steps.
Variable DISPLAY define where put output.
export DISPLAY=:0.0 - This mean that you try put output on local display of your server.
Correct:
export DISPLAY=<ip_ of_ workstation_Xmanager>:0.0
In this case X-session will use own IP connections without encryption.
SSH can forward X-sessions inside ssh connections.
In this case you should not define variable DISPLAY. Check that profile script not redefined DISPLAY.
SSH server will do it automaticaly. For check:
echo $DISPLAY

Error while fetching variable value from sqlserver database in 11g

Hi
We created a dynamic variable to fetch data from sqlserver database in 11g.But when we test it, it is erroring out as follows: "nqserror: 27024 the execute physical statement must specify a physical sql statement to execute".
Please help to overcome this issue.
Thanks.

Hello,
First make sure that you're able to retreive data from the repository (right click on a table and view data?)
To create a session variable follow these steps:
From the Administration Tool menu bar, choose Manage > Variables.
In the Variable Manager dialog box, from the menu bar, choose Action > New > Session > Variable.
In the Session Variable dialog box, type a variable name.
Names for all variables should be unique. The names of system session variables are reserved and cannot be used for other types of variables.
For session variables, you can select the following check boxes:
Enable any user to set the value
Check box that allows you to set the session variables after the initialization block has populated the value (at user login) by calling the ODBC store procedure NQSSetSessionValue(). For example, this allows non-Oracle BI Administrators to set this variable for sampling.
Use the Initialization Block drop-down list to select an initialization block that will be used to refresh the value on a continuing basis.
To add a Default initializer value, perform one of the following steps:
To use the Expression Builder, click the ellipsis button to the right of the Default initializer work space.
Type the value into the Default initializer text box.
Click OK.
you can do the same for a repository variable except that you will have to specif a refresh interval.
Make sure the sql your are issuing is correct by running it first using a client.

Enabling Flashback

Hi,
when I enable flashback using the following -
define the FRA ( db_recovery_file_dest_size and db_recovery_file_dest )
ensure the DB is in archive log mode
set the flashback_rentention_target
alter database flashback on;
what exactly am I enabling ?
Is it the underlying requirements for all the flashback tools ( eg flashback query, table, database ) ?
What about flashback table drop ?
I have a database that does not have the FRA defined and has not enabled flashback, yet I am able to issue
flashback table <name> to before drop;
why can I do this if flashback is not enabled ?

I think you are enabling the flashback logs, which allow you to issue the 'flashback database' command. Flashback Drop uses the recycle bin. The other ones use UNDO data.
