Oracle 10 database from Shared to dedicate mode..??

Hi ,
Could anyone tell me how to change a database in shared mode to dedicated mode.
Thanks in advance.

Werner,
At first the database is in dedicated mode and I have changed it to shared mode yesterday. Maximo(tool) is running on that server as I changed to shared one the maximo application is running slow(may be the reason dedicated->shared) so here people are saying me to convert again it to dedicated mode even I say that it may not be the right reason.But I have to change it as per their wish dynamically.
So could you please tell me how to change the database to dedicated dynamically . I converted it to shared dynamically so hopefully there will be a solutoin for my query..
Thanks in advance

Migrate Oracle 11g database from Windows To Linux using RMAN hot / cold backup ?

Hi Friends,
Is it possible to Migrate Oracle 11g database from Windows To Linux using RMAN hot / cold backup ? ( as i would like to perform Point In Time recovery)
(or) The only way is to use RMAN convert as mentioned here - Transporting Data Across Platforms
(or) Is there any other method (except exp/imp and data pump)
Regards,
DB

HI
his post describes the procedure required to migrate a database from Windows to Linux using the RMAN Convert Database command.
Both Windows and Linux platforms have the same endian format, which makes possible to transfer the whole database, making the migration process very straightforward and simple.
To migrate between platforms that have a different endian format, Cross Platform Transportable Tablespaces (XTTS) needs to be used instead.
List of Steps Needed to Complete the Migration
The migration process is simple, but as it has several steps it is convenient to be familiar with them before running it.
1. Check platform compatibility between source and target OS
2. Start the database in read only mode
3. Check database readiness for transport from Windows to Linux using DBMS_TDB.CHECK_DB
4. Check if there are any external objects
5. Execute the Rman Convert database command
6. Copy converted datafiles, generated Transport Script and Parameter File to Linux
7. Edit the init.ora for the new database
8. Edit the Transport Script and Parameter File changing the windows paths to Linux Paths
9. Execute the Transport Script
10.Change the Database ID
11.Check database integrity
Thank you

Moving Oracle 9i database from AIX 5.2 to AIX 5.3

Hi,
We are planing to move few of our Oracle 9i databases from AIX 5.2 to AIX 5.3 on another server. Will offline backup/restore work in this case ? The databases are fairly big (> 1 TB each). Looking for some advice.. Thanks.

Hi Kamran,
As the DBs are fairly large ( approx. 1 TB each), how long it would take to copy the databases to the target server using RMAN DUPLICATE .. ? Do you think offline backup/restore would be a better approach ? Both the source and target boxes are co-located in the same data center. Thanks !
Rgds,
HimansuI assume that RMAN will be more faster than hard copy/paste (cold backup). I can't say how much it will probably take to take RMAN DUPLICATE, but it should be faster than cold backup

Installing JDBC driver to connect to Oracle 8i Database from Weblogic 10.3

I want to connect to Oracle 8i database from weblogic 10.3 application server. I found a classes12. zip file on Oracle.com to use as driver for the same.
I am also connecting Oracle 9i database from the app server. Now if i replace the classes12. jar from the lib folder won't it disallow me to connect to the Oracle 9i database.
2ndly the claases12.zip file i found from the site is for jdk 1.2 will it create any problems. Please let me know
Kindly let me know what is the standard procedure to install a new driver in Weblogic 10.3.

I tried to install weblogic 10.3 using jdk 1.5.07 but. it is not supported. Moreover from the sites also i found that it's only the application wars and ears compiled in jdk 1.5 need not be recompiled in 1.6. But no reference of jdk 1.5 is there.
I tried to use thin client from the code and connect to Oracle 7i
i got the following exception.

Migrate oracle 9iR2 database from Suse to Red Hat???

Hi Everyone,
We're going to move an oracle 9iR2 database from Suse to Red Hat. At this moment I don't know the detail about the platforms yet. I still like to ask a question if DB backup on Suse is compatible on RedHat? Physical restoring may be our prefer instead of exp/imp.
Any advices?
Thanks,
Eric

I'm pretty sure (never did it myself) that there will be not problem when moving the database. The Oracle software is the same (at least when you use the x86 version) so
the format of the datafiles and controlfiles should be identical.
However some configuration files (network settings) might differ so try before you die :-)

Moving oracle 9i database from windows 2000 to windows 2003 server

hi everybody,
plz provide me a solution how to move oracle 9i database from windows 2000 server to windows 2003 server with step by step and also with commands plz as i am very new to oracle
thanks in advance
suresh

Install 9i on windows 2003 server and patch to the same level as the Oracle on Windows 2k
Shutdown and make a cold backup of your old database. That includes datafiles, controlfiles, redo files, init file (spfile)
Copy and put these files to the exact same directory structure/location, for example if old file is under D:\oradata\mysid\ then the file on new file should be under same directory. (If you are using Network Storage that make things easier, just mapping to the same drive letter.)
Also make sure archive log dest and all dump dest directories are created. You don't have to copy all old logs and dump files over.
Use oradim to create a new service for the database instance
http://www.psoug.org/reference/oradim.html
Set proper ORACLE_HOME, ORACLE_SID envionment varibles
Run netca to configure listener, actually copy listener.ora and tnsnames.ora to $ORACLE_HOME\network\admin will do
Try to start the database

How to connect to an Oracle XE database from Forms

Hello,
I have just installed Oracle XE on my computer. After that I downloaded Oracle Developer Suite. My intention is to build programs with Forms. This forms program shall manage data stored in my Oracle XE database.
My question is: How to connect to the Oracle XE database from forms. In forms developer I have tried to connect the database with the command Ctrl+J. Then I registered username, password and oracle instance (orcl). It will not work!
best regards
Håkan Axheim

Hello,
the tnsnames.ora must have been updated with the XE information.
the SID for Xpress Database is always XE
XE =
(DESCRIPTION =
    (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = TCP)(HOST = 127.0.0.1)(PORT = 1521))
    (CONNECT_DATA =
      (SERVICE_NAME = XE)

Moving Oracle 9i database from AIX server to Sun Solaris 9 server

I want to move my oracle 9i database residing on AIX server to Sun Solaris 9 server.
The database residing on AIX server has the following features :-
1. It is a production database.
2. Running in NOARCHIVE LOG Mode.
3. It was Live for few weeks, hence transactions are stored on it.
4. It has one schema,around 700 tables & 129 views.....etc
5. Huge downtime is affordable.
What is the safest way to do so ??
Yachendra

Hi Yachendra,
1. It is a production database.
2. Running in NOARCHIVE LOG Mode.By the way do you have any idea that PRODUCTION databases are always kept in ARCHIVE LOG Mode. It's is highly advice able.
3. It was Live for few weeks, hence transactions are stored on it.If you are really serious about your data and don't want to lose anything and wants to perform CROSS PLATFORM you must make sure that you have all your achive logs.
my oracle 9i database residing on AIX serverYou have already got the solution regarding that. Maran has told you for EXPORT/ IMPORT and Burleson has given you enough documents to consult.
Thanks

Unable to establish a connection to Oracle 9I database from Developer Forms

I've installed the Oracle 9I database in the Windoes NT server with SID = ORA9i. Using the SQL*plus coming with oracle 9I database, I can connect to the database. I've also installed the Developer with Forms 6I and Reports 6I in the same computer. I tried to establish a connection to the Oracle 9I from Developer through "Oracle Net8 Easy Config". After giving the settings, when I do a connection test, it is giving the error "TNS Could not resolve the Service Name".
the following is the entry in the 'tnsnames.ora' file
TEST9I.WORLD =
(DESCRIPTION =
(ADDRESS_LIST = ((PROTOCOL = TCP)(Host = ntserver)(Port = 1521))
(CONNECT_DATA = (SID = ORA9i))
Can somebody tell me how to make a connection from Developer (Forms6I and Reports 6I) to Oracle 9I database.
Thank you.

hi matz,
i tried this one too, but it is not working. giving the same error. if i've making a connection thru the 'Oracle Net8 easy config', it is giving the following error at time of connection test.
The test did not succeed.
ORA-03106: fatal two-task communication protocol error
There may be an error in the fields entered
or the server may not be ready for a connection.
You can check the server and retry, or continue.
this is the message i'm getting. but i couldn't find any error in the fields i entered.
if i'm editing the 'tnsnames.ora' file and make the connection, and when i open the Form builder and try to connect to the database, it is giving a memory error.
the instruction at "0x67614f04" referenced memory at "0x000000160". The memory could not br "written".
i don't know why it is happening. i can connect from the same forms to Oracle 8i database. is there any additional settings we need for Oracle 9i on windows platform?
regards
george

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.

Please put your comments here as early as better. I do appreciate your kind help.For sure it is double work, To copy backup files on UNIX host.
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.

Export oracle 10g database from one server to another.

I need to export some databases from production to testing server.

This i clearly documented in this table per export and import modes (traditional tools).

Unable to Connect to Oracle 10gR1 database from JDeveloper 11g using OCI

We are migrating our application from OC4J to Weblogic server. As a part, I am trying to create a database connection in JDeveloper 11g (11.1.1.3.0 - Build JDEVADF_11.1.1.3.PS2_GENERIC_100408.2356.5660) to Oracle 10gR1 database. Previously I had Oracle 10g Client installed in the machine. Created a database connection using OCI driver and when I try to test connect, I got "Test Failed: no ocijdbc11 in java.library.path". I searched through Metalink and forums and one suggestion was to install Oracle 11g Client on the machine where Jdeveloper 11g is installed. I installed 11g R1 client and tried the same test connection using OCI driver. Now I am getting "Test failed: ORA-12705: Cannot access NLS data files or invalid environment specified" error.
The same database connection works good with Thin driver with both Oracle 10g client and 11gR1 client.
Previously I had Jdeveloper 10.1.3.2 and Oracle 10g Client and I was able to connect to database without any errors.
Could you provide me the steps for this or if I missed any steps?
Steps to Replicate:
For the error: no ocijdbc11 in java.library.path
1) Install JDeveloper 11g (With embedded Weblogic Server)
2) Install Oracle 10g Client on the same machine
3) Create a database connection in the "Application Resources --> Connection"
4) Use OCI driver. Enter the host details about the Oracle 10g R1 database
5) Test connect to the database.

Any ideas and pointers would be great.

1. will my problem get solved after i install oracle 11g client on my machine.Yes, your problem should get solved. The version of the Oracle 11g Client must match the version of the JDev's JDBC drivers. Alternatively you may install an Oracle 11g Client and replace JDev's Oracle JDBC drivers with these from the installed client. Please, read carefully my 1st posting above in this thread.
2. can i patch JDeveloper 11g on my machine to work with 10g client, or can i do the same with 10g client.You might succeed if you replace JDev's built-in JDBC drivers (which are 11g versions) with 10g versions, but I do not recommend you to try that because JDeveloper 11g and ADF 11g may be using some 11g features that do not exist in 10g drivers, so you may have problems.
I also have PLSql developer installed on my machine and it works well.PL/SQL Developer does not use JDBC drivers, so it is not an relevant example in this case.
My generall recommendation is to use Oracle JDBC Thin drivers. Oracle claimed that OCI drivers had better performance, but this was really true about earlier releases. Current Oracle 11g JDBC Thin drivers offer excellent performance and they offer all the features of the OCI versions (which was not true about earlier releases). In my opinion, the most important disadvantage of Oracle JDBC OCI drivers is that most versions have native memory leaks so all the RAM would get consumed after long application execution. The fact that WebLogic Server does not offer Oracle JDBC OCI drivers by default anymore says that Oracle discourages the usage of the OCI driver in favour of Thin driver.

Cannot connect to Oracle 11gR2 database from SQL Server 2005

Both SQL Server (Windows) and Oracle (Linux) are in 64bit environments.
I have done the following on a Windows 2008 R2 with SQL Server 2005:
Install InstantClient from Oracle Database 11g Release 2 Client (11.2.0.1.0) for Microsoft Windows (x64) to C:\Oracle
Install oledb from 64-bit ODAC 11.2 Release 3 (11.2.0.2.1) for Windows x64 by executing install.bat oledb c:\oracle odac
Note: Not sure whether 11.2.0.2.1 version of ODAC will cause any problem since I cannot find 11.2.0.1.0 version.
I have checked the Allow inprocess of OraOLEDB.Oracle provider in SSMS.
I have executed sp_addlinkedserver @server = 'ORACLE_TEST', @srvproduct = 'Oracle', @provider = 'OraOLEDB.Oracle', @datasrc = '##.##.##.##:1521/TEST'
The ##.##.##.## is the ip address of the Linux server which has the Oracle 11gR2 database TEST.
I have executed sp_addlinkedsrvlogin @rmtsrvname = 'ORACLE_TEST', @useself = 'FALSE', @rmtuser = 'xxxx', @rmtpassword = 'yyyy'
The xxxx is the oracle username and yyyy is the password for the oracle user xxxx.
I know the oracle database TEST is up since I have setup connection in Oracle SQL Developer having:
##.##.##.## as the hostname
1521 as the Port
xxxx as the username
yyyy as the password
TEST as the service name
When I click Test Connection for the linked server ORACLE_TEST in SSMS, it just hang.
When I issue a query like select count(*) from oracle_test..xxxx.table1, it just run forever. I'm not so sure how to query an oracle table. I have also tried select count(*) from oracle_test.xxxx.xxxx.table1.
When I retype the password in the Linked Server Properties, it just run forever.
Do I need to create a tnsnames.ora on the Windows machine?
Do I need to change the tnsnames.ora on Linux machine?
I'm very new to Oracle.

This forum is dealing with connections from an Oracle database to SQL Server - so the Oracle database is the driving site and this is the way round from your linked server set up.
