Move a database from one server to another

Hello All,
I am using Oracle 11g R2 on Oracle Enterprise Linux 32 bit.
I have 2 servers , LinuxActive and LinuxPassive. I am trying to dismount the file system of the datafiles and control files ... from one server and mount it on the other.
I previously opened a thread here concerning this subject and reached a result that it can be done, now i have questions about the details.
I have installed Oracle software on both servers where ORACLE_BASE is /u01/app/oracle and ORACLE_HOME is /u01/app/oracle/product/11.2.0/db_1 on both servers.
I created an orcl database on LinuxActive where all its datafiles, control files, redo logs, flash_recovery_area is on a disk group mounted under /oradata.
I want to dismount /oradata from LinuxActive and mount it to LinuxPassive and start up the orcl database from LinuxPassive instead of LinuxActive.
I may need to revert back /oradata to LinuxActive.
What steps should I do? should I migrate my spfile also to /oradata?
Should I create an orcl database on LinuxPassive?
Do I start up my database like i do when i build an Oracle dataguard database ? from a pfile of the old database?
Regards,

RMAN duplicate will be simpler.
As you are in 11g, you can perform duplicate from active database.
Create PFILE in new location,
Change "CONTROL_FILES" parameter to new mounpoint.
Perform RMAN duplicate
In both the cases you have to take care of parameters, DB_FILE_NAME_CONVERT & LOG_FILE_NAME_CONVERT.

How to move SQL database from one location to another location i.e. from C' drive to D' drive

Hi, How to move SQL database from one location to another location i.e. from C' drive to D' drive ? please share some link.
Thanks and Regards, Rangnath Mali

Hi Rangnath,
According to your description, my understanding is that you want to move databased from C drive to D drive.
You can detach Database so that the files become independent, cut and paste the files from source to destination and attach again.
There are two similar posts for your reference:

You seem to have ignored Dude's VERY good advice and continue to press down this ill-advised path. If you continue this approach, you WILL have problems at the very time you do not need any additional problems. Trying to recover your production database at 2:00 in the morning is not the time to be getting errors from rman because it can't find what it needs - because you decided to move them around yourself.
Please reconsider.

How can you move the objects from one server to another?

how can you move the objects from one server to another?

Hi,
Collecting objects for Transporting
1. rsa1->transport connection
2. left panel choose 'object type', middle panel choose 'infocube' and 'select objects'
3. then choose your infocube and 'transfer'
4. will go to right panel, choose collection mode 'manual' and grouping only 'necessary objects'
5. after objects collection finished, create request
6. If they are $TMP, then change the package.
7. When you click the Save on the change package, it will prompt for transport. Here you can provide an existing open transport request number, or if you like here itself you can create a new one.
8. You can check the request in SE09 to confirm.
Releasing Transport Request
Lets say you are transporting from BWD to BWQ
Step 1: In BWD go to TCode SE10
Step 2: Find the request and release it (Truck Icon or option can be found by right click on request #)
Note: First release the child request and then the parent request
Steps below are to import transport (generally done by basis )
Step 1: In BWQ go to Tcode STMS
Step 2: Click on Import queue button
Step 3: Double Click on the line which says BWQ (or the system into which transport has to be imported)
Step 4: Click on refresh button
Step 5: High light the trasnport request and import it (using the truck icon)
Transport

How Can I Copy an database from one server to another ?

Hi All,
I need to copy an existing database from one server to another server. I want to maintain all the settings from the source database.
I´m not used to Oracle database and i´d be glad for any help.
How can I do this ? Do I need to backup and restore in the other server ? Do I need to copy files from one server to another ?
Any help will be really appreciated.
Carlos.

I think a simpler approach, other than using RMAN, is to do a database export from the source and then import them into the target database. But you will need to do some ground work on the target, i.e, create database, tablespaces, and schemas (with their name the same as those in the source database.)

Migration databases from one server to another

Hi All
I want to migrate our 8 production databases from one server to another server. these are in RAC .Details are below
OLD SERVER: -
OS: REDHAT LINUX 3
ORACLE: ORACLE 10gR1
FILE SYSTEM : OCFS
STORAGE: SAN
Its a RAC databases
NEW SERVER: -
OS: REDHAT LINUX 5
ORACLE: ORACLE 11g R2
FILE SYSTEM:ASM
STORAGE:SAN ( fresh one)
Its also RAC DATABASES
So please tell me the best method to migrate 8 databases from old server to another server . all databases size are not more than 50 GB.
All servers details are above .please let me know if you require any other details
please reply soon we have to do it on urgent basis

Since all your databases are small (< 50G), I would recommend using expdp/impdp - http://download.oracle.com/docs/cd/E11882_01/server.112/e17222/expimp.htm - as this will provide several advantages as listed in the document.

Moving CMS database from one server to another

Using the following:
Crystal Enterprise 10, installed on W2K3 Server R2 (not making any changes to this server);
CMS database, installed on W2K Server, SQL Server 2000, SP3
New database server: W2K3 Server R2, SQL Server 2005, SP2
I found what I think are the steps to moving the database from one place to another in the CE10 Administrator's guide (pages 291-300, but I want to make sure there aren't any "gotchas" when moving the database location and/or upgrading the database version. I'm primarily a DBA, so I already know about the Schema security change going from SQL 2000 to SQL 2005.
In a nutshell, here's my plan:
1. Take fresh backup of the existing CMS database
2. Stop Crystal Management Server
3. Click "Specify CMS Data Source" on the toolbar.
4. ETC--following the steps in the admin guide
If anyone has done this and has run into any problems (what I'm expecting) or had it go smoothly (I would be surprised), please let me know what to expect.
Thanks!

All you really need to do is stop the crystal services.
Backup the CMS and Auditing database
Detach the CMS and Auditing database
Copy CMS and Auditing databases to new DB server
Attach the CMS and Auditing databases
Set the compatibility mode
On the servers/s that host the CMS service, modify the ODBC connections to point to the new database server
Start the CMS service, fire up the Crystal services.
One thing to note, I don't think SQL 2005 is a supported platform for CE10 - this doesn't mean it won't work and since the support lifecycle for the product is long gone it doesn't really make much difference however you may want to run some thorough testing prior to the move.

How to copy/move Portal database from one machine to another?

I am receiving a ORA-22973 error (size of object identifier exceeds maxmum size allowed) on the wwsec_enabler_config_info$ table when attempting to import my entire "portal30" schema from one database to another on different Windows NT Servers.
Background: I had Portal 3.0.9.8 installed, configured, and running with the following setup:
Machine 1: Windows NT 4.0 SP 6, Oracle 9iAS 1.0.2.2, Oracle Portal 3.0.9.8
Machine 2: Windows NT 4.0 SP 6, Oracle 8i Database 8.1.7.0.0
We no longer have use of Machine 2 and needed to move the database over to Machine 1.
I performed the following steps:
1. Installed Oracle 8i database 8.1.7.0.0 on Machine 1.
2. Set up the tablespaces in the database on Machine 1 to match the same names and sizes of the tablespaces in the database on Machine 2.
3. Used the Oracle "exp" command to export the entire database that resided on Machine 2.
4. Copied the ".dmp" file to Machine 1.
5. Used the Oracle "imp" command to import the entire database on Machine 1.
6. The import completed successfully with warnings. But I had received the ORA-22973 error during the import process.
7. After it completed I compared the list of tables and packages in the "portal30" schema between the two databases. The wwsec_enabler_config_info$ table is missing.
8. I tried to export and import only the wwsec_enabler_config_info$ table between the two databases, but continue to receive the ORA-22973 error.
Without the table being created, access to the portal cannot be achieved.
Here are my questions:
1. Is there anyway to create the wwsec_enabler_config_info$ table without receiving the noted error?
2. Is there any other workable way to get the portal database from Machine 2 to Machine 1?
I am aware of the portal import/export utilities but that would require me to run through the 2 hour install of Portal 3.0.9.8 on the database on Machine 1 and then individually export and import all the portal components (security, pages, applications, content library, etc). I merely wanted to transfer the entire database from one machine to another, so I felt the Oracle exp/imp utilities would be quicker and less work.

Hi,
I've been hitting problems with Portal 3.0.9.8.1 against 8.1.7.2.1 on NT - i.e., Intermedia not working at all, and have been advised by support to move back to 8.1.7.1.1.
I don't want to lose any of my content in the Portal since the db upgrade and am wondering on what is the best way to do this.
The version of the Portal will be the same so I am hoping I can just use the Portal export and import utilities, as afterall, it is just data and the schema structures are the same between db versions. I'm also hoping that the Portal export doesn't use the standard Oracle EXP tool as it doesn't work anymore on 8.1.7.2.1 on NT!!

John

Move Web service from one server to another

Hi
        i am calling a web service from R3 which i have moved from one server to another what i need to do in my web dynpro application as it will call the web service from new location?

Hi,
Try with this code. Dynamically Server will get change.
Create a HTTP Destination in visual administrator which stores the server name and port.
String prefixURL = "http://";
// your Service Address...remove the first part from service url.
String serviceURL = "/TestService/Config1?style=document";
DestinationService dstService = (DestinationService) obj;
Destination destination = dstService.getDestination("HTTP","ApplicationServer");
Properties destprop = destination.getDestinationProperties();
HTTPDestination httpDestination = (HTTPDestination) destination;
String serverName = httpDestination.getUrl();
prefixURL = prefixURL + serverName;
String testURL = prefixURL + serviceURL;
Request<Obj> testReq = new Request<Obj>();
testReq._setEndPoint(testURL);
You need to import below files into your project.
import com.sap.security.core.server.destinations.api.Destination;
import com.sap.security.core.server.destinations.api.DestinationService;
import com.sap.security.core.server.destinations.api.HTTPDestination;

Error while duplicate database from one server to another server

Hi there,
I am practicing duplicate database from one single database server to another server. Hardware and driver path on 2 machines is the same. Here are my steps:
--------------------- Clone site:
1. modify listener.ora with content:
LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
(ADDRESS = (PROTOCOL = TCP)(HOST = localhost.localdomain)(PORT = 1521))
ADR_BASE_LISTENER = /u01/app/oracle
SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(GLOBAL_DBNAME = orcl)
(ORACLE_HOME = /u01/app/oracle/product/11.2.0/db_1)
(SID_NAME= orcl)
ENABLE_GLOBAL_DYNAMIC_ENDPOINT_LISTENER = ON
2. stop and start listener again, message show like :
Service “orcl” has 1 instance(s).
Instance “orcl”, status UNKNOWN, has 1 handler(s) for this service…
The command completed successfully
3. create pfile from spfile.
4. shutdown and startup nomount with pfile is new pfile create from step 3.
--------------------------------------- Source site
1. modify tnsnames.ora with content like:
VVCOREDB =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = localhost.localdomain)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = vvcoredb)
ORCL =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP) (HOST = 10.254.1.235) (PORT=1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = orcl)
2. run command from rman like these:
rman> connect target sys@vvcoredb
rman> target database Password:
rman> connect auxiliary sys@orcl
rman> auxiliary database Password:
rman> DUPLICATE TARGET DATABASE to orcl from active database spfile nofilenamecheck;

How to move SQL database from one host to another ?

Hi,
We need to move the database of P1 7.0 from one host to other.Please advice if there are any documents I can refer for this operation.
I believe if we maintain the same host name for the new system it is just database movement and PI should not even be aware of this operation!!
Thanks & Regards
Mrutyunjay

Hi,
      We have a system R / 3 Enterprise Edition 47x200 running with Microsoft SQL Server 2005.
     Copy the BD in another machine (server), then applied script note 551915 (user_restore.sql) and finally proceeded to install the central instance of SAP (sapinst) with existing database option, but it does not appear that the error attached:
Errors during EMP database check on produccion4; reported errors:
Error by Compatibility level check: Database EMP has wrong compatibility level
Error by Dbo objects check: Database EMP contains user objects belonging to system user dbo
; correct reported errors before continuing with the installation
     hope someone can give us some help on diagnosing the issues, thaks.
Best regards,

How to 'move' databases from one server to another

Hi there
Here is a brief description of my assignment.
We have two Redhat Linux 4 64-bit server where two Oracle 10.2.0.4 64-bit database are running (one on each server).
<li>DB on server1 is using Filesystem for storage.
<li>DB on 2nd server is using ASM.
<li>Size of both is between 75-80GB.
<li>I have to move both the databases to new servers (same platform) with minimum downtime.
<li>There is no upgrade required during this move/migration. Both DBs have to be brought over as-is.
<li>The new servers may be on VMWare - I am not sure it at the moment. But please let me know if that will make any difference.
I would highly appreciate if someone could please provide me with some high-level guidelines to perform this move.
Best regards

Hi Srini
Thank you so much for sharing the valuable URLs.
I am reading through "Cloning An Existing Oracle10g Release 2 (10.2.0.x) RDBMS Installation Using OUI [ID 559304.1]" and I have few questions.
<li> This MOS says:
NOTE: This note should only be used for cloning single-instance (non-RAC) homes. It should not be used for cloning RAC, CRS or ASM homes.If that is the case, how should I clone ASM-Home?
One of the environments that I have to migrate to a new server has ASM installed as well. And couple of oracle databases (10.2.0.5) on that server are using ASM for storage.
<li>If were to do a fresh installation of 10gR2 RDBMS and ASM homes (on Redhat Linux 64-bit), I guess I need to contact Oracle Support (open an SR) to access the software, right?
<li>How to check from existing installation which patches I need to download and apply to this fresh installation in order to make it same as the existing installation? "opatch lsinventory" gives me a long list of number/fixes - I don't know which patch(es) to download.
Please advise!
Best regards

Move ASM disks with database from one server to another?

I have a 11.2.0 ASM with a 11.2.0 database on two internal disks on server1. The disks are not in any raid or volume manager configuration, i.e. they are just two disks. The disks were physically removed from server1 and installed on server2, which is the same hardware, OS, patch level etc, in the same target position. Installed the 11.2.0 rdbms and grid infrastructure binaries on server2; changed the raw disk partition ownership to oracle and started asmca. asmca does not see the disks.
My question, is this possible and if so, what am I missing?

I did not manually create an ASM instance and try to add the diskgoup. My understanding is, if you use asmca then it starts an ASM instance, if one is not already running, and lets you configure your diskgroup. This is what I am trying to do, with no luck (asmca does not see the disks)I may be totally wrong here but afaik dbca creates the ASM instance. ASMCA is just for adding disks or diskgroups......
Did you try to create an ASM instance with dbca? When doing so do not put your disks in there - this will create a new disk group.....
