Restoring 10g database to 11g

Hello Experts,
I have to migrate the 10.2.0.4 database to 11.2.0.3 database and trying to search some RMAN option.
Can anyone let me know how to do it. I do not want to restore sys and system from 10g to 11g.
Thank you....

Hi,
The way I've done it earlier, is to do a clean install of 11g, creating tablespaces and users corresponding to the ones in the 10g instance, and then "restored" the user data through exp(dp)/imp(dp).
I don't think that RMAN supports restoring into a different version.

Upgarding 10g database to 11g

I have created 10g database in Linux .
Now I want to upgrade it to 11g.
I have installed 11g software in my Linux machine .
I logged in as sysdba and then I did shut down the 10g db . Later I started it up in upgarde mode and tried running catupgrd.sql.
But I got the error as ORA-01722: invalid number
When I looked into catupgrd.sql script I found this information
The following statement will cause an "ORA-01722: invalid number"
error if the database server version is not correct for this script.Shutdown ABORT and use a different script or a different server.
SELECT TO_NUMBER('MUST_BE_11_1') FROM v$instance
WHERE substr(version,1,6) != '11.1.0';
So I checked the columns of v$instance
SQL> select instance_name,HOST_NAME,VERSION,STATUS,DATABASE_STATUS,ACTIVE_STATE from v$instance;
INSTANCE_NAME HOST_NAME VERSION STATUS DATABASE_STATUS ACTIVE_ST
learn11 ap6108rt 10.2.0.1.0 OPEN MIGRATE ACTIVE NORMAL
What should be done to change the version ?

Later I started it up in upgarde mode and trUsing which home? 10g or 11g?
Is the database still in 10g home?

How to create a database in 11g from an archive taken from 10g

Hi
I appreciate that some of you may find this a silly question, but it is a situation that has been given to me.
The situation in detail is that I am working on project where a part of a company has been sold off to someone else and I am working on part of the separation of IT Systems. The old company has supplied archive (ARC) files containing data that relates to the company which is being sold off. There are files such TSN, listener, and control files. The source data originated from an Oracle 10g database, but it is not possible to download a copy of 10g anymore, and so I have downloaded the earliest version of 11g. I have installed 11g without creating a new database, and my questions are as follows:
1) Is it possible to re-create the database on the supplied data from the archive logs
2) If possible, how do you so it - step by step (I am not a DBA but a Microsoft .Net Developer.
Thanks
Andy

Yes, the DBA has supplied a backup of the database. All I am looking to do is to create from this backup. Is there a simple GUI that can do this for me with minimal touch? As I said I just need step-by-step instructions that can guide me through this so I don't muck it up!
As with many things Oracle the answer is: it depends.
There are too many potential differences between the (unknown) features your 10g database used and the feature set of 11g.
This doc link will give you a sense of how just 'unstraight forward' it can be.
http://docs.oracle.com/cd/E11882_01/server.112/e17222/upgrade.htm
In particular see this section:
Using the Pre-Upgrade Information Tool
After you have installed the software for Oracle Database 11g Release 2 (11.2) and any required patches, Oracle recommends that you analyze your database before upgrading it to the new release. This is done by running the Pre-Upgrade Information Tool from the environment of the database you are to upgrade. The Pre-Upgrade Information Tool is a SQL script included with Oracle Database 11g Release 2 (11.2) software. This is a required step if you are upgrading manually; otherwise, the catupgrd.sql script terminates with errors. Running the Pre-Upgrade Information Tool is also recommended if you are upgrading with DBUA, so that you can preview the items that DBUA checks.
In other words, the normal upgrade path involves performing checks against the CURRENT 10g database to identify any real or potential problems.
Those checks are done BEFORE you take the 10g backup.
You should also search the net for 'oracle 11g restore 10g backup' and read some of the many threads that have been posted with your same question. They will give you a sense that the process can be problematic and dependent on the type of backup (cold, hot) and how it was taken (manually or RMAN).
Your best chances for success are to do things the 'normal' way. That means contacting Oracle support to get the discs/download for 10g and then installing 10g and recovering the 10g database from the current 10g backup. The closer you can make the recovery environment and instance configuration the same as the original the fewer problems you are likely to have.
Or have the old company provide either the original 10g discs or at least provide the installation, control file and configuration information so you can recover the 10g database correctly.
As already suggested you should first make sure you have a reliable COPY of those backup files and you should use that copy for all of your testing of recovery settings.
Please tell us if you think you will be able to obtain the 10g software for reinstallation or not.

Restore and recover Oracle 10g database from tape.

I have a very basic question for restore and recover Oracle 10g database. Our envirnment settings are:
Oracle 10g on Unix, daily database and archivelog backup to Vista NetBackup server. Retention policy is 2. Old backup files are copied from NetBackup server to the tape for record keeping.
I want to restore a database to a point in time. Because our retention policy is setup to 2. The backup files I need have been copied to the tape. So I should ask SYSTEM ADMIN to copy the backup files back to NetBackup server disk or I can ask him to copy backup files to the Unix server that host my Oracle 10g database. Then I can use Rman to do restore and recover. Is this doable? I know normal procedure is to copy backup files I need back to NetBackup server disk, not directly back to database server. Please put your comments here as early as better. I do appreciate your kind help.

Are you using catalog or nocatalog?
If the backup information is out of retention, Catalog them again also in netbackup.
So that you can able to restore database directly without copying those files to host.

Restore 9i database from tape to 10g ASM

We have a plan to upgrade 9i database to 10g ASM. The current 9i database is using file systems on AIX5L. This is a VLDB of size >3TB. I want to restore production copy to test environment. There is no test environment for this database now. So, if I want to restore to test, we need 3TB for file systems and another 3TB for ASM disk groups for migration. Instead, Is there any way I can restore production Oracle 9i backup directly into Oracle 10g ASM disk groups. So that, we can save 3TB of space allocation for file systems. Also, it will save time instead restore 9i database to test, upgrade to 10g and then migrate to ASM.
I agree that this is the space to be allocated temporarily. But, as per our company standards, the project needs to procure temporary space too.

You cannot restore a 9i RMAN backup into 10G.
You can use either export/import or transportable tablespace.
You can use below method:
1. Use transportable tablespace to migrate 9i to 10G.
2. Initially migrate all datafiles to filesystem.
3. Then migrate all datafiles to ASM.
Apart from this , you have one more option . upgrade existing 9i database to 10G and the use RMAN to restore it to 10G ASM database.

WAY TO IMPORT DATA FROM 11G DATABASE TO 10G DATABASE?

Hi All,
I have a requirement to take an full export dump of an Oracle database and import it fully to a 10g database.
I have never touched 11G until now and would like to know whether the 11G expdp will be downward
compatible so that I can use the dump file(created by 11G expdp) to import it to 10G(using 10d impdp).
Or if it is not possible, can you please brief me the steps I should follow here?
Note: I have only 11G installed in this server.
Regards
Satish

Oracle's Data Pump (expdp) utility has a VERSION parameter. Here is an excerpt from the documentation:
VERSION
Default: COMPATIBLE
Purpose
Specifies the version of database objects to be exported. This can be used to create a dump file set that is compatible with a previous release of Oracle Database. Note that this does not mean that Data Pump Export can be used with versions of Oracle Database prior to 10.1. Data Pump Export only works with Oracle Database 10g release 1 (10.1) or later. The VERSION parameter simply allows you to identify the version of the objects being exported.
Syntax and Description
VERSION={COMPATIBLE | LATEST | version_string}
The legal values for the VERSION parameter are as follows:
    * COMPATIBLE - This is the default value. The version of the metadata corresponds to the database compatibility level. Database compatibility must be set to 9.2 or higher.
    * LATEST - The version of the metadata corresponds to the database version.
    * version_string - A specific database version (for example, 11.1.0). In Oracle Database 11g, this value cannot be lower than 9.2.
Database objects or attributes that are incompatible with the specified version will not be exported. For example, tables containing new datatypes that are not supported in the specified version will not be exported.
Here is a link to the documentation.
Hope this helps!

Preparing for Oracle OCA 11g using an Oracle Express 10g database

As a software application developer, I have been considering Oracle certification for a while to enhance my skill set. Unfortunately I don't have access to a commercial Oracle installation, and would like to use a free version of Oracle Express during my studies. The latest OCA courses largely focus on Oracle 11g, and it would appear that there is no free (Express) 11g database available yet.
Could anyone please advise me whether it would be possible and practical to prepare for the 1Z0-051 Oracle Database 11g: SQL Fundamentals I and 1Z0-052 Oracle Database 11g: Administration I exams using an Oracle Express 10g database instance, while accompanied by the relevant Oracle 11g study material? In other words, is the overlap between Oracle 10g and 11g sufficient that a solid understanding of 10g could allow me to successfully sit the 11g exams? Furthermore, would the Express edition of the database provide sufficient functionality to prepare for the Administration exam?

(http://education.oracle.com/pls/web_prod-plq-dad/db_pages.getpage?page_id=41&p_org_id=1080544&lang=US&p_exam_id=1Z0_051 says Exam 051 has been validated against Oracle Database 10g and Oracle Database 11g. Training on either version will be appropriate preparation.).
For 1z0-052 the situation is different. Oracle 10g express edition hides some of the administration tasks ... you really need to be using 11g.
If you dont waht Oracle 11g all over your regular machine then I would typically recommend install Oracle Enterprise Linux either on a spare machine with a dual core or HT processor and with 2GB or more of memory (eg Dell gx280 or better); or using a virtualisation solution on your current machine (ram would need to be 3GB or higher) (eg virtualbox or whatever ... though windows as a guest can have a license issue).

Authenticating 10g databases against OID 11g

Hi.
Our client currently uses OID 10g to authenticate users on their 10g databases. They intend to begin an upgrade to 11g beginning with the OID upgrade. Some applications though are likely to remain on 10g databases for the foreseeable future.
Will it remain possible to authenticate existing 10g database installations against the new OID 11g setup?
If so, will this happen automatically as part of the OID 10g->11g upgrade steps?
Many thanks.

Hi Sridhar
Did you come right with the Oracle case insensitive connection? I am at a client site and they are asking if I can create an Oracle case insensitive connection and need to know how to do this.
I have come right now. I have added the following into the parameters in the universe:
NTS_COMP = LINGUISTIC
NTS_SORT = BINARY_CI
When running a query the selection does not have to be case sensitive. eg. In the database it shows as "SOFTWARE" and if I run a query looking for "software" it returns the correct data.
Thanks

How To Restore corrupted Oracle 10g Database

Hello Guys,
We have Oracle 10.2.0.3 database installed on Itanium server.
1. One day we found some packages got invalid & not compiling at all with error –
ORA-00600: internal error code, arguments: [4097], [], [], [], [], [], [], [].
2. Then we successfully restored the database from old RMAN backup of previous date that caused this error.
3. After 2 days again we found the same error in alert_prd log -
ORA-00600: internal error code, arguments: [ORA-00600: internal error code, arguments: [4097], [], [], [], [], [], [], []
ORA-06512: at "SYS.DBMS_STATS", line 19089
4. Then for testing we exported database using exp command & found 3 tables are not exporting because of data block corruption issue.
5. Then we truncated the data from all 3 tables and then able to export successfully.
6. After all this we manually run SYS.DMS_STATS job but found same error logged in prd_alert log.
This looks like, still database block corruption issue is there & we are unable to cure it 100%
This is a production system & in very critical state now.
Please looking for a help from all of you expert guys to resolve this issue.
Thanks in advance,
~Amol

Hello;
I don't believe you have an issue that RMAN can solve. Since you have an ORA-600 I would use Oracle support.
There's an Oracle MOS doc on this :
ORA-600 [6008] Generated Due To Underlying ORA-01410 [ID 743661.1]
It's an exact match of your version and line number.

You just upgrade them. But you need to takecare of certain things as you are a 10g user. Refer below link for the prerequisite
