How to imp database for a recover

Hi Experts,
We have a database as oracle10G R4 in 32 bit window.
I makk a full database exp as a backup.
At the present, i find some data file is missing in user dev tablespace.
My question, we do not have a schema or tablespace exp dump file.
For exiting DB, Do we need to drop all tablesapce (include sys tbs) and recreate tablespaces for imp full database recover?
Thanks for help!
JIM

Hi,
If you have a full database export, you can perform a full, table, schema, or tablespace import from this. If you want to just recover a tablespace, then you would want
1. drop that tablespace from the database
2. create the tablespace as you want it
3. run import with a tablespace filter:
impdp user/password directory=your_dir dumpfile=your_dumpfiles tablespace=your_tablespace ...

How to shrink database for the Oracle

Hi,
As you know, in the Sql server database there is a "shrink database" for the shrink the database space, but how to do that for the Oracle9i?
Any comments would be appreciated.
Thanks a lot

You will have to resize ur datafiles to shrink ur db. Here are the steps
1) select file_name,file_id,bytes from dba_data_files;
This will give u the current size of datafiles.
2) select file_id,sum(bytes) from dba_free_space group by file_id;
This will give u the free space in the datafiles. If the file_id is not listed in this query that means the file is fully occupied/used.
(used space = bytes col from query 1 - sum(bytes) col from query 2)
3) alter database datafile file_id resize ### ;
Enter the value you wanna resize based upon ur req. You cannot shrink the datafiles below the used space.

How to recreate database for UCM

I was able to change the DB connection from one to another by change the settings through "System properties". however, there were some database objects(tables) created during the UCM installation. is there anyway I can switch to new database and get UCM database objects recreated without re-installing the UCM? there seems some sql scripts in the database directory, but I'm not sure how to run them, the order and parameter are not clear to me.
Thanks

Hi
One thing that you can do to recreate the default tables and columns is to run the all.sql script on the DB which is specific for your db .If you want to just recreate an image replica then extract the ddl statements from your current db and put it in a sql script and execute that directly on the other db instance . In this case make sure to change the instance specifc details in the ddl script extracted and replace them with the newer instance details like the table space name , user name executing it and like wise.
Another way would be to use Archiver to create export batch file for the Tables and then importing them to the target instance. The way out for this is to go to Archiver Applet - Create New Archive - Export - Tables and here and include all the tables that are there in the content server.
Hope this helps
Thanks

Library recovery: how can I recover a library after I get this message: There was an error opening the database for the library "/Users/Jim/Pictures/Libraries/K2 Library.aplibrary"???

Library recovery: how can I recover a library after I get this message: "There was an error opening the database for the library “/Users/Jim/Pictures/Libraries/K2 Library.aplibrary”???

Thanks a lot, Frank. The lsregister did the trick! I am testing this on 10.8.2.
http://support.apple.com/kb/TA24770 : I deleted the "com.apple.LaunchServices.plist", and restarted the Finder, even logged off and on again; did not change anything. The file has not been recreated, so it may not be used anymore.
http://itpixie.com/2011/05/fix-duplicate-old-items-open-with-list/#.ULZqa6XAoqY
The direct "copy and paste" from the post did not work: I had to retype it :
/System/Library/Frameworks/CoreServices.framework/Versions/A/Frameworks/LaunchSe rvices.framework/Versions/A/Support/lsregister -kill -r -domain local -domain system -domain user
but then it worked like a charm!
Cheers
Léonie
And btw: I turned on the "-v" option for the lsregister to see, what was going on, and saw plenty of error messages (error -10811); so I repeated the command with "sudo". After that I still saw five iPhotos. Repeating as regular user finally got rid of the redundant iPhoto entries. It looks like registering as super user may be causing this trouble.

How to add multiple databases for a single frontend

We have a project based on distributed databases and we have to workout on .Net framework.I want to know some information of connecting multiple databases for a single frontend and how can we access them.
If so we have connected 2 databases for a single frontend in future if I want add one more database to it how it will be possible to do it without disturbing the current connectivity.
Please help me in resolving this problem.
Thanks......

hi,
what do you mean by connecting 2 databases? can you explain further?
using entityframework you can connect to different databases
public class CustomerContext : DbContext
public ReportContext()
: base("DefaultConnection")
public DbSet<Customers> Customers { get; set; }
and your connectionstring (config file)
<connectionStrings>
<add name="DefaultConnection" connectionString="Data Source=(LocalDB)\v11.0;AttachDbFilename=D:\\Database\Project.mdf;Integrated Security=True" providerName="System.Data.SqlClient" />
</connectionStrings>
you can add more connection strings on it.

How do I search for all "missing" tracks within the iTunes database?

I found the dreaded ! of death, and sadly I verified the tacks indeed are not on my hard drive.
Is there a way to sort on this tag so that I can see what else might be missing on my hard drive but remains in the database (sort of similar to how you can search for all tracks that have missing artwork)?

Thanks. It works perfectly.

How can i use a database for practice in DOS

i have some problems in the sqlplus.
My OS is windows2000 server,when i intalled the Oracle 8i
i type a command 'cmd' go to DOS.and type "sqlplus username/password@database"
but always the system say that my database name can't be deal with.
and i want to get a sample database for training SQL statements.How can i get it.
is Oracle 8i have the sample database.

It sounds like your database hasn't been started yet so do this:
Try typing svrmgrl at the c:> -- if it doesn't work you might either have to go to the proper directory or type sqlplus to get an sql:> prompt (I don't remember it's been a while) but the rest I am pretty sure about---
When you get the svrmgr prompt:
use (i think) "connect internal"
and "oracle or Oracle" as password
once you do this
it should say connected
then use: svrmgr:>shutdown -- shutsdown DB
then use: svrmgr:>startup -- starts DB
hopefully then you can access your database through SQL Plus

I downloaded Aperture and now I'm getting a "There was an error opening the database for Library " and I can't do anything else. How can I fix it so I am once again able to run Aperture?

I Downloaded Aperture from the Apple Website then proceeded to download all my picture's frp, IPhoto. The very next time I opened Aperture an error poped up stating, There was an error opening the database for Library "blank". I can't do anything with the program but hit the cancel buttom which closes the program. How do I fix it?

Is "blank" the name of your Aperture Library? If not, then Aperture is pointing to the wrong Library. Hold down the option (⌥) key while you launch Aperture by clicking it in the Applications Folder. Then select the correct library and press the "choose" button.
If that does not help, try to repair your library:
Locate Aperture library in Finder. Holding down the keys option (⌥) +command (⌘) and double click on Aperture Library to show the First Aid dialogue:
Then try to start Aperture again. If that also should fail, try the other steps in Aperture 3: Troubleshooting Basics: http://support.apple.com/kb/HT3805
Good Luck

How to determine database growth for new B1 instalation

Hello B1 people,
I'm working on the capacity planning of my new business one project and must know how to determine database growth. Does anyone did something like that before?
Wich tables should I consider?
Thanks in advance.

Hello Gabriel,
I think it is difficult to make any predictions about database growth because this depends on the volume of your business transactions, the number of users, the continuity of your master data...
For example a small number of users can create a lot of transactions (accounting, logistics) with big documents like sales orders with more than 100 items, or a lot of users who primarily look up things but only create small transaction won't create too much data and thus influence database growth in totally different ways.
You should collect information about the volume of daily business to make any forecasts.
If you start with an empty database, the first big growth will be when you upload your master data, but if only few business transactions follow, you shouldn't use that first increase for your calculation.
Is this your very first B1 installation, or do you already have B1 systems running? If you use the EWA service on a running B1 installation on a regular basis, then you will get a good impression of database growth and transaction volume but you should only use this as a basis for your calculation if the business of the new installation is similar to already running company's.
Hope that helps,
Sandra

How to use the mirrored and log shipped secondary database for update or insert operations

Hi,
I am doing a DR Test where I need to test the mirrored and log shipped secondary database but without stopping the mirroring or log shipping procedures. Is there a way to get the data out of mirrored and log shipped database to another database for update
or insert operations?
Database snapshot can be used only for mirrored database but updates cannot be done. Also the secondary database of log shipping cannot used for database snapshot. Any ideas of how this can be implemented?
Thanks,
Preetha

Hmm in this case I think you need Merge Replication otherwise it breaks down the purpose of DR...again in that case..

Aperture (3.4.1) no longer opens and the following message appears: There was an error opening the database for the library "/ Users / Andrea / Pictures / Aperture 3 Library.aplibrary." How can I solve this problem? Thanks

I was using Aperture (3.4.1), when he appeared a notice that asked me to stop the Mac with the power button. When I restart Aperture no longer opens and the following message appears: There was an error opening the database for the library "/ Users / Andrea / Pictures / Aperture 3 Library.aplibrary."
How can I solve this problem?
Thanks

After a system crash your Aperture Library may be corrupted, because Aperture may not have been able to finish the ongoing database transactions.
Have you tried the Aperture Library First Aid Tools?

Try "Repair Database", and if this does not help: "Rebuild Database"

Hi,
You need to a script and run it on os level. Here is an example:-
emcli relocate_targets -src_agent=agentmachine1.domain:3872
-dest_agent=agentmachine2.domain:3872 -target_name=RACDB

How to create database item for fast formula?

Hi,
Is there any document for how to create database item for fast formula? I could not find in Metalink or this forum. Thanks.
Andy

Oracle ship many pre-delivered Database Items plus they're created automatically when you create Input Values (etc).
There's often something already there for you. If there's not, you usually create Fast Formula functions to retrieve other data. You don't create your own custom DBIs; Oracle don't deliver APIs for that.
