Looking to move 3 Databases into RAC
Hello,
I have just started at a company the has three different applications running on three different databases running on three different servers. They want them to all be highly available. So I think RAC. However I do not want to have three separate RACs one for each Application/Database. Is it a sound practice or even possible to put all three servers into a RAC (3 Node) and have the three databases running in that single 3 node RAC?
Hi,
yes it is possible, and even best practices.
Oracle recommends to build bigger clusters and put multiple databases onto it => though database consolidation would even more increase the ROI.
Note that if you build a 3 node cluster, your databases don't have to run on all 3 servers at the same time.
I know of big clusters (> 16 nodes) with multiple databases, where a single database does not run on more than 2 nodes at the same time.
There are just few things to regard, when running multiple databases on the same server, like setting CPU cound.
If you search for database cloud on OTN you might get more information on this.

Converting Single Instance database into Oracle Fail-Safe on Linux
Hi All,
We have single instance Oracle10g database running on Linux RHEL4. We are looking to convert this database into Oracle Fail-Safe (Active-Passive). Does any one have document for Oracle fail-safe setup?
Regards,
TusharTushar,
you can't use software for windows on Linux.
However, there's number of ways to implement high-availability solution on Linux Oracle.
You can go with Active-Active (RAC) - which means that you'll have two servers attached to the same database at the same time. You can use either, and if one goes down(due to power failure for instance), the second will still be available.
You can go with Active-Passive (Data Guard) - which means that you'll have one of the nodes being active and the second passive, but synchronized with the first one, so in case of failure of the first node you can activate the second one.
You can also go with linux clustering - which is most similar to MCS + fail-safe - you'll have two nodes clustered with linux clustering software (RH cluseter suite for instance) and connected to shared storage. One node is active, and in case of crash database instance will be automatically started on the second node. This is beneficial because you can use your resources more efficiently. In case if you have two databases you can run each of them on dedicated server and then, in case of node failure move to another one. However, the setup of such configuration is quite cumbersome. -
Is it good idea to move 500GB database to another drive?
Hello Experts,
I have Exchange server 2013 on Windows server 2008 R2 Standard. All the roles are installed on single server.
I have a single database in D drive and the size of database is around 500 GB, The drive is about to full.
I have another partition(E drive) with 1.8 TB storage and planning to move this database into this drive? is it good idea to move this size (500 GB) database to another drive?
Or
Should I create a new database in other drive, which has 1.8 TB storage and move mailboxes one by one.
Please let me know, what is the best practice for it.
Thanks in advance!!
Thanks, ManojHi,
There is no downtime if you create new database on new drive and move mailbox to it. Moving mailbox doesn’t shrink the old database file, you need to delete the original database after you moving mailbox to new database.

Want to upgrade 8.1.5 database into 10.2.0.2 and implement RAC.
Hi,
I have two different databases running on 8.1.5.0 and 8.1.7.4 and the size of databases are 110GB and 130GB.
Now we want to upgrade this database into 10.2.0.2 and implement RAC.
Could any one suggest the best way/document to upgrade database into 10g.
Existing Platform is Sun Solaris 5.8(32 bits)
New Platform is AIX 5.2(64 bits).
ThanksSince the database is being migrated from Solaris to AIX, you cannot physically copy the database to the new server. You can choose to use Oracle's export and import utilities. This depends on much downtime you can afford. You can also create a new database on the AIX server and use CTAS (create table as select) to bring over your tables. This requires some additional post-migration work on your part to re-create the indexes, constraints, default values, etc. Export/import will do most of this for you.
If you have the option to upgrade to Oracle 10gR2, another possibility is to upgrade your database on the Solaris server and use transportable tablespaces to create a new 10g database on the AIX server. Transportable tablespaces in 10gR2 allow you to migrate across operating systems. Be sure to review Oracle's certification matrix to ensure that you are installing Oracle database software on a certified platform. -
How to migrate multiple ACS database into one ACS database ?
Hey All,
we just purchased several companies and as IT/network department, we need to consolidate all the ACS from the HQ and the purchased company into one ACS, I read the cisco docs. mentioned, I can export the migration file from the old acs and upload it into the new acs serve.
but my concern is we have multiple acs server, will the the muliple acs migration files overwrite each other during the upload into the new server.
thanksRaghavender -
I am not an expert on MySQL migration, but you would look to migrate the database to a local Oracle Database and then move that to your Database Cloud Service. However, keep in mind that at this time you can only access the Database Cloud Service from outside the Cloud via RESTful Web Services, so you might have to modify the application that accesses the database. Hope this helps.

Move entire database instance to new hard drive
I'm running SQL Server 2012 over Windows Server 2008 R2 SP1 on a Hyper-V host (also on 2008 RS SP1).
I used a fixed sized virtual disk and I don't care for how I allocated the space. So I just wanted to create a new virtual disk, then take the entire instance and move it from the existing VHD to the new one.
Is this possible?
I also researched trying to shrink a VHD -- that seems to be equally as daunting and potentially fraught with issues.
I also looked into moving the entire instance from one server to another (build a new server then move the instance), but what I seemed to find is that this is not supported.
I have a mission-critical database on the SQL Server (though it's not that large), and currently have a test of SharePoint in the same instance. Is this best practice? One instance for all the databases? I was also thinking of using SQL Server as a back
end for an Apache web server.
Any ideas? (Thanks in advance!)

You cannot move entire instance it would require uninstall.But you can move user and system databases to drive which you desire.
SQl server service restart will be required

How to make two standalone oracle databases into master/slave relationship
i'm not talking about RAC...
is there any way to make two oracle databases into master/slave relationship? one is hot one is cold, when the hot one is down, the cold one automatically picks up? and of course two databases are in sync all the time.
any experience?DataGuard is an enterprise edition feature.
You could roll your own standby database by cloning the production system to a backup server and writing scripts that copy the archived log files from the primary to the standby and that apply the archived logs on the standby. Of course, the transactions that had been applied to the primary that were still in the primary's redo logs would be lost if the primary were to fail. DataGuard provides options to keep the standby more closely in sync with the standby to reduce or eliminate that risk, which is one of the reasons that it's an enterprise edition feature.
If you're on Windows, Oracle FailSafe may also be something to look at.

</html>i think normally u will get data from databsae as objects.they are like java beans having getter and setter methods.so you create a collection of those objects like collect all the objects coming from database into an arraylist or....
suppose you want to populate the dropdown box with say "username" from database object s, your code will look like that
<html:select property="name">
<html:options collection="databaseList" property="username" />
</html:select>
"databaseList" is collection(say.. ArrayList) of objects you are getting from database.this dropdown will contain all the "usernames" you are getting from database. -
How To register The manually Created Database into DBCA
hi guys .. !! -:)
using test linux 4 with the vmware , manually i create RAC database , the database is working proper , i planned to delete the RAC database through DBCA , but when i issued $dbca !!! the database can not be see from DBCA to delete it or to manage it
so i don't know is there is any configuration file belong to DBCA to detect the existing database or there is
command to register the database into DBCA
note:-
i added the instance name into the /etc/oratab
but it's not working
also i tried to use this command
$dbca -silent -adddb database_name also this command is not work perfectly
so really i don't know what is the step i have to follow to let the DBCA detect my existing database
with my regard

How do I move a document into a folder in PDF reader on an iPad
How do I move a document into a file in PDF reader on my iPad
When you're looking at the list of documents, touch the Edit button at the upper-right. Then select the file you want to move by touching the check box to its left, and click the Move File icon, it's the third one from the left at the top of the screen. You'll be prompted to "Move selected document" after which the "Choose a location" dialog will appear to allow you to select a destination folder.

When I click on the preview pane to move a photo into the edit pane, there is no image just a black square and the edit buttons are not active. A few images in an event will move to the edit pane but most will not. I cannot work with those images that do not enter the edit pane..no attaching to email, make a card, slideshow, etc.
There are several possible causes for the Black Screen issue
1. Permissions in the Library: Back Up and try rebuild the library: hold down the command and option (or alt) keys while launching iPhoto. Use the resulting dialogue to rebuild. Include the option to check and repair permissions.
2. Minor Database corruption: Back Up and try rebuild the library: hold down the command and option (or alt) keys while launching iPhoto. Use the resulting dialogue to rebuild.
3. A Damaged Photo: Select one of the affected photos in the iPhoto Window and right click on it. From the resulting menu select 'Show File (or 'Show Original File' if that's available). (On iPhoto 11 this option is under the File -> Reveal in Finder.) Will the file open in Preview? If not then the file is damaged. Time to restore from your back up.
4. A corrupted iPhoto Cache: Trash the com.apple.iPhoto folder from HD/Users/Your Name/Library/ Caches...
5. A corrupted preference file: Trash the com.apple.iPhoto.plist file from the HD/Users/ Your Name / library / preferences folder. (Remember you'll need to reset your User options afterwards. These include minor settings like the window colour and so on. Note: If you've moved your library you'll need to point iPhoto at it again.)
If none of these help:
As a Test:
Hold down the option (or alt) key key and launch iPhoto. From the resulting menu select 'Create Library'

Script/Automator Get Filenames in Folder and Move Each File into Folder based on Filename?
I have searched for an answer to this and I have searched through multiple file renaming apps on the app store too but alas I cannot find anything that does what I want so I ended up looking into Automator as my saviour but I am a total NOOB.
What I want to do is point automator to a folder of my choosing
Automator then takes each file in that folder and creates a folder with the same name as the file and then move the file into that subfolder.
Sounds easy enough eh
I'm totally stumped, anyone have any guidance ???This is a PITA to do in automator - automator does not handle loops the way it should - but in applescript it looks like so (open this in the applescript editor, select the file you want to run it on in the Finder, then run the script):
tell application "Finder"
set mainFolders to the selection
-- selection returns as a list, so even if there's only one folder a loop is used
repeat with thisFolder in mainFolders
--get the folder's contents
set containedItems to every item of thisFolder
repeat with thisItem in containedItems
-- get name of file, add 'ƒ' to avoid name conflicts
set newFolderName to (displayed name of thisItem) & " ƒ"
--make folder, move item
set newFolder to make new folder at thisFolder with properties {name:newFolderName}
move thisItem to newFolder

Moving SAP Database into another Hardisk
Hi Expert
I want to move all WG55 database into another free space hardisk under MMSQL 2000 enterprise edition , I have 3 database to move on Eg R:\WG55DATA1,WG55DATA2,WG55DATA3 and K:\tempdb.mdf
All the above database are in D:\WG55DATA1,WG55DATA2,WG55DATA2,tempdb.mdf so what is the best option to move all WG55 database to R and K respectively It is live Production system so i would be thankful if any expert person in MMSQL to guide me please
and I am using another server for application (Instance)
regardsthe sap note above is well explained.
but, you may use SQL Enterprise manager.
1. stop sap.
2. detach Database (Enterprise manager, on DB Name -> All Tasks->Detach Database
3. Move Data and log files to new location
4. Database -> All Tasks -> Attach Database and find the MDF file (the first data file) from the new location. (you may have to find each of the data and log files)
5. verifiy it is correctly attached.
6. Start sap -
Hi all,
Can anyone tell me, how to find whether my DB is RAC or not? Its bit urgent. Thanks in advance!!!
Regards,
Mithra.Following is the extract from the link posted:
1.)The primary and standby databases must be running Oracle Database 10g (10.2) and each can be installed in either a single-instance or multi-instance environment. The database must be licensed for Oracle Enterprise Edition or Personal Edition.
2.)You must use a server parameter file (SPFILE) to ensure the broker can persistently reconcile values between broker properties and any related initialization parameter values.
3.)The value of the DG_BROKER_START parameter must be set to TRUE. (Enterprise Manager sets this parameter automatically.)
4.)If any of the databases in the configuration is a RAC database, you must set up the DG_BROKER_CONFIG_FILEn initialization parameters for that database such that they point to the same shared files for all instances of that database. The shared files could be files on a cluster file system, if available, on raw devices, or stored using Automatic Storage Management (ASM).
5.)Oracle Net Services network files must be set up on the primary database and on the standby database if you configure an existing standby database into the broker configuration. Otherwise, Enterprise Manager automatically sets up the network files when it creates a standby database.
6.)If you are using a nondefault port number (for example, something other than port 1521) for the local listener address, you must set the LOCAL_LISTENER initialization parameter on each instance that is part of a broker configuration to a listener address that is reachable by all members of the configuration. See the Oracle Database Reference and the Oracle Database Net Services Administrator's Guide for additional information.
7.)To enable DGMGRL to restart instances during the course of broker operations, a service with a specific name must be statically registered with the local listener of each instance. The value for the GLOBAL_DBNAME attribute must be set to a concatenation of db_unique_name_DGMGRL.db_domain. For example, in the LISTENER.ORA file:
LISTENER = (DESCRIPTION =
(ADDRESS_LIST=(ADDRESS=(PROTOCOL=tcp)(HOST=host_name)
(PORT=port_num))))
SID_LIST_LISTENER=(SID_LIST=(SID_DESC=(SID_NAME=sid_name)
(GLOBAL_DBNAME=db_unique_name_DGMGRL.db_domain)
(ORACLE_HOME=oracle_home)))
8.)Any database, including instances of the database, managed by the broker must be mounted.
9.)If any of the databases in the configuration is a RAC database, the START_OPTIONS for that database must be set to MOUNT in the Oracle Cluster Repository (OCR) using srvctl as follows:
srvctl add database -d <db_unique_name> -o <$oracle_home> -s mount
or
srvctl modify database -d <db_unique_name> -o <$oracle_home> -s mount
The primary database must be opened in ARCHIVELOG mode.
10.)You must set the COMPATIBLE initialization parameter to 9.2.0.1.0 or higher for both the primary and standby databases. However, if you want to take advantage of new Oracle Database 10g features, set the COMPATIBLE parameter to 10.2.0.0.Regards.
