Can we rollback catcpu.sql using flashback database?

Hello all,
Can we use FLASHBACK DATABASE to roll back the changes made by the catcpu.sql/catpatch.sql used for upgradation/patching? [ I am aware that oracle provides rollback sql's but just curious. ]
TIA,
JJ

Keep in mind, catpatch is only the second part of the patching process, before that you already patched the software. If you want to have a complete rollback, follow the instructions in the readme file.

Can I use flashback database to flashback a pluggable database?

Hi All,
I created a container database and then created a pluggable database.
In the pluggable 12.1 datbase, I loaded the user data.
I performed the below
sqlplus / as sysdba;
create restore point CLEAN_DB guarantee flashback database;
And I performed the transactions on the pdb.
Now my intention is to restore to the restore point CLEAN_DB as created from the above step.
If I perform the below, will it restore my pdb to the initial state?
flashback database to restore point CLEAN_DB;
Regards,
Kamal.

Hi,
You cannot use FLASHBACK DATABASE for pluggable database.
Flashback query/versions queryis UNDO based and work in PDB’s
Flashback transaction query/flashback transactionis UNDO and REDO based and work in PDB’s

Can we create pl/sql code over database link?

Hi All,
We are using Oracle 9i database.
I want to know if we can create or modify pl/sql code (procedue, package, etc) over the database link? That means - can we create a procedure in remote database using the db link?
Thanks,
Dnyanesh

yes, I can connect to the remote database directly and create/modify the packages.
But I want the users not to create them using the db link.
Is there any way to create the pl/sql package over database link?
Thanks,
Dnyanesh

Can I migrate from sql azure business database edition (old) to sql azure standard database edition (new in preview)?

I have an export .bacpac file from a sql azure business database edition and I want import that file to sql azure standard database edition.
I have tried through Azure but I think that is not supported yet.
I have also tried through Microsoft SQL Server Management Studio 2012 but Wizard only shows me old editions "web" and "business" for destination database and it is incompatible...
Thanks.

I've done this today.
You'll need to restore your database onto Azure as a Business/Web addition. Either use your existing or New > SQL Database > Import.
Then you need to sign up to the SQL Preview https://azure.microsoft.com/en-us/services/preview/.
Once you've done that, in the Azure portal under DB > Scale, you'll have Web, Business, Basic, Standard and Premium to choose from.
Obviously this is still in preview mode.

How can I rollback a transaction using EJBContext.rollbackOnly()?

I failed to rollback a "required" method of a seesion bean using EJBContext.rollbackOnly() , but it rollbacked if I throw EJBException , how can I rollback a transaction by

The full and partial updates (whether it be Thunderbird, Firefox or SeaMonkey) from mozilla.org are only provided to the official builds and not builds built yourself or by a third-party.
The openSUSE and other Linux distro provided builds have their own ways of package updates in their package manager.
However if the poster is using Thunderbird for Linux from http://www.mozilla.org/en-US/thunderbird/ (64-bit Linux is on ftp) then those preferences would be valid and work.
Nothing is being gutted as it has been this way since forever with third-party builds whether on Windows, Mac OSX and Linux.

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.

How can i configure an odbc using a database from sql to my excel

Hi, i hope you can help me
I have an excel sheet in wich i'm working, but i need to import data from a database used SQL, but i need the ODBC connection,... I try to used the administrator ODBC, but it has no driver for me to connect it to the SQL database, ... who knows wich tool can i use?
best regards,
Pamela

As far as I know -you still can't do that with the mail app on a device. You can select each contact by tapping the blue + sign to open the contacts app and you have to add them one at a time.
These are third party apps that will let you do this - Group Email ... And there are others in the app store.

T-SQL USE : Reference Database in Different Server

I'm fairly new to SQL so perhaps I am missing something but what I am trying to do is have a script I wrote select a certain database depending on @@ServerName. This script will be run by the testing department and needs to work regardless of connection.
IF @@SERVERNAME IN ('X')
    USE DataBaseA
ELSE IF @@SERVERNAME IN ('Y')
    USE DataBaseB
ELSE
    USE DataBaseC
What happens is DataBaseB does not exist on server X so I receive the error of "no database exists". As well, DataBaseC lacks certain columns in tables that DataBaseA has (DataBaseC will later get these columns but are not there right now).
Is there a different way to force the code to properly use the right database and not throw errors?

Interesting. I was not aware of that.
I suggest you resort to dynamic SQL if possible.
Build your SQL command into a variable, write only one USE STATEMENT into it and run it via EXECUTE.
More about dynamic SQL at
MSDN or from Erland Sommerskog.
Another option could be using SSIS and work with variables there.
Or go to powershell and cmd get the Servername there and fire up sqlcmd with the right commands (you can use parameter -d instead of use).
In the end there could be quite a bunch of work involved depending how much you have to do in your script.
Cheers
Martin

Can i open an SQL express 2005 database in SQL server express 2012?

Hi,
i have a database and it's in SQL express 2005 but because my windows 8 is not compatible with the installer, i have to install the latest 2012 installer. my problem now is that i cannot open it in the 2012 edition..what do i have to do?

Hi white_roses,
Could you let us know how do you restore the database to SQL Server 2012 Express edition? Please help to collect the detail error information of this issue, it will benefit for us to do further investigation.
As Sandesh and ED suggested above, we can directly detach our databases from SQL Server 2005 and then attach them to SQL Server 2012. For detail steps, please refer to the following article:
http://msdn.microsoft.com/en-us/library/ms187858.aspx
After we move a database from the instance of SQL Server on server A to the instance of SQL Server on server B, users may be unable to log in to the database on server B. If need the logins information on Server B, please refer to the following article:
http://support.microsoft.com/kb/918992
If you have any question, please feel free to let me know.
Thanks,

FLASHBACK Database : rman vs sql command differnces

I am new to Oracle and want understand the difference and which is the correct way of flashing back the database?
RMAN command vs SQL Command on using FLASHBACK DATABASE
SQL> FLASHBACK DATABASE TO RESTORE POINT BEFORE_ONLINE_TEST; {CODE} Vs rman> run{
     flashback database to restore point BEFORE_TEST_320130313;
     sql "alter database open resetlogs"; }
Referring this article on http://docs.oracle.com/cd/E11882_01/backup.112/e10642/rcmflash.htm#BGBDCAFA it says we can use both RMAN and SQL command for database flashback.
Questions:
1. Difference between using RMAN and SQL command on database flashback?
2. When to use RMAN or SQL on the database flashback?
3. Which is the Oracle recommended or best way ?

How to use Flash recovery area only for flashback database feature

I would like to use flash recovery area only for flashback database feature, which means, flash recovery area will store only flashback logs.
I dont want to use that file system for any other files, like archive log files, database backups, control file copies, multiplex redo log, etc
is it possible? I want to use this feature only for flashback database option and hence i dont want to disturb any existing configuration in my database
including backup jobs. Is it required to store archive redo log files also in flash recovery area to use the flashback database feature?
I certainly can't afford to have a copy of entire database in this file system as size of my DB is more than the flash recovery area file system I have.
Thanks
Sarayu

Aman,
I think i was not clear in my question. Let me try again
My only requirement is to use flashback database feature (or be prepared to use if required). I dont want to create a large file system to use this FRA to store all these files. Out of all the files being stored here copy of data files seems to be consuming more space. I see these files are classified as transient and permanent files. I am okay with permanent files. I fear that this file system may consume more space if i store backup files on disk. I want database backups to go to tapes, not to the FRA disk. Is it possible?
Thanks for your reply
Okay, well in that case you can use RMAN and push the backups to the tape drives. FLB logs would be stored on the FRA.

iam not able to recover the dropped tablespace using flashback database,,,iam tried this many times some time iam able to recover ,most of time iam getting above error only.
anyone help me,,
pl share ideas.
Thanks in advance;

See flashback limitation
You cannot use Flashback Database alone to retrieve a dropped data file. If you flash back a database to a time when a dropped data file existed in the database, only the data file entry is added to the control file. You can only recover the dropped data file by using RMAN to fully restore and recover the data file.
so after dropping tablespace,you can't perform flashback.
