This is a documentation forum.
You need to read that documentation.
Specifically, go to http://docs.oracle.com, select the version of the database you are working with, and put 'clone' into the search box. One link for 10gR2 is http://download.oracle.com/docs/cd/B19306_01/server.102/b14220/startup.htm#sthref1874
IN the future, please have the courtesy to
1) post in an appropriate forum, as described by the title of the forum

10g Rel2 How to clone a database in another machine suggestions

Hi All,
We have 2 solaris boxes(prodn & backup) and our new requirement is to clone the production on the backup server.
a) If my understanding is correct , does the cloning helps to backup the changes in the production database automatically ?
b) If by any chance if production database server is down will the backup server database take over it automatically ?
c) Or can we use grid here or any other suggestions?
This is not a large database and we have max of 1gb Data with 25 users.

How shoud I start. Please assist me.As endian formats are different for Solaris 8 and Redhat (solaris has big, but linux has little), then the easiest way is to use exp/imp utiltiy for migration data.
exp full database from 8i and import it in 10g. You can exp only particular schemas, it really depends, what kind of data you need, how much data You need to import and so on. But exp/imp is the answer how to get data into new database.

How to create a clone of database from STANDBY?

How can i clone a database from physical standby database?

Steps to clone from standby:
1. cancle the managed recovery process on standby
sql>alter database recover managed standby database cancel;
2. Remember your standby databse would be in mount mode.
3. Connect to the auxiliary instance and to the standby database through RMAN
rman target sys/<pwd>@standby auxiliary sys/<pwd>@auxiliary-connection
4. If 11g, then run directly duplicate from active database
rman>duplicate target database to 'auxiliary_db_name' from active database nofilenamecheck;
5. Once, the duplication is done, start the MRP on the standby again
sql>alter database recover managed standby database disconnect from session;
Ok..You are on 10g.
Perform the above steps, but only thing is 1st you need to take the backup of the standby database first.

How to recreate the database only?

Hi All,
We are having some dictionary blocks corrupted in our application database. The solution is to recreate the database and import the whole database into this new database. Details of product we are having
OS : RHEL- ES 3
Application : 11.5.9
Database : 11.2.0.3
Now our main consideration is:
1) How to recreate the database without reinstalling the applications.
2) Is there any special consideration to follow?
3) What will be the impact of recreation of database on Applications?
Pls help me in this matter.
Thanks and Regards
Amit Raghuvanshi

You can use the above command to just install the Oracle Home in a new path.
But, i am not sure if export / import works or not. May be other experts can comment on this.
If you have a physical backup, it would be better to clone the db rather than Export / import.

Clonning the Database

how to clone database (production DB)? please provide me steps to follow

Step 1
The first step is to locate all database files and the init.ora file.
SQL> select name from v$database;
SQL> select name from v$datafile;
Step 2
Create missing folders on new server or location
Step 3
The next step is to copy the database files to the new location. The database you are cloning must be down before you copy any files to ensure the SCN is correct.
Move the init.ora file
Step 4
Change the init.ora to your new name. Change the value to db_name from old name to new name.
Additional parameters you may need to change:
audit_file_dest
background_dump_dest
control_files
core_dump_dest
log_archive_dest
user_dump_dest
Step 5
Issue this SQL command on the old database :
SQL> alter database backup controlfile to trace;
Edit the trace file so it appears as:
STARTUP NOMOUNT
CREATE CONTROLFILE SET DATABASE "NEWNAME" RESETLOGS NOARCHIVELOG
MAXLOGFILES 16
MAXLOGMEMBERS 3
MAXDATAFILES 100
MAXINSTANCES 8
MAXLOGHISTORY 454
LOGFILE
GROUP 1 (
'/u01/app/oracle/oradata/NEWNAME/redo01.log',.....
Save as script and move to the new location.
Note the SET DATABASE in the CREATE CONTROLFILE statement..
Note: The Redo logs don’t appear until the database is opened, but this script creates them.
Step 6
Make sure your new init is in the /dbs folder
Make sure you moved and renamed the password file
Run
SQL> @cr_control.sql
Step 7
Open the NEW database
Before opening the NEW database, you will need to perform incomplete recovery. After recovery you can open the database using the RESETLOGS option as show below:
SQL> alter database recover database until cancel using backup controlfile;
SQL> alter database recover cancel;
SQL> alter database open resetlogs;
Note: The first command produced an error. It wanted archive that did not exist, I also did not move any archive over to the new system.
The second command should be run regardless of the error and it should run without error. If the third command runs without error you probably have a successful clone and your redo logs should be present.
Step 8
Note: I would setup the new database using NETCA before starting this step.
Change the DBID number (make sure the init.ora has remote_login_passwordfile=SHARED)
1. Check the DBID before change
SQL> select dbid , name from v$database ;
2. shutdown immediate;
3. startup mount
startup mount pfile='/u01/app/oracle/admin/NEW/pfile/initNEW.ora'
4. execute NID
nid target=sys/oracle@NEW (oracle should be the sys password)
5. Create a new password file
Rename the old right now if it’s the same name
orapwd file=/u01/app/oracle/product/10.1.0/dbs/orapwNEW password=oracle entries=50
Note: oracle is the sys password
6. startup mount pfile='/u01/app/oracle/admin/NEW/pfile/initNEW.ora'
7. SQL> alter database open resetlogs;
Database altered.
8. check the new DBID
SQL> select dbid,name,open_mode,activation#,created from v$database;
Step 9
Check the new database name.
SQL> select name from v$database;
Step 10
Create a binary init.ora file
SQL> create spfile from pfile='/u01/app/oracle/admin/NEW/pfile/initNEW.ora';
Restart the database

How to use Logical database in function module?

I will create a function module in HR.
but how to use Logical database in function module ? Logical database PNP always show screen.in function (RFC) code , it is a matter.

You cannot attach the LDB to the main program of the function group.
- So you may [SUBMIT|https://www.sdn.sap.com/irj/sdn/advancedsearch?cat=sdn_all&query=submit&adv=false&sortby=cm_rnd_rankvalue] a report which use the LDB and get back the data (export/import), by default in the syntax of SUBMIT the selection-screen will not be displayed
- Use [LDB_PROCESS|https://www.sdn.sap.com/irj/sdn/advancedsearch?query=ldb_process&cat=sdn_all], fill a structured table for selection, and get data back in another table
- Use [HR function modules to read Infotypes|https://www.sdn.sap.com/irj/sdn/advancedsearch?cat=sdn_all&query=hrfunctionmodulestoread+Infotypes&adv=false&sortby=cm_rnd_rankvalue].

How to create a database for sample code from Tutorial/Book?

I want to try out the sample code from [http://shop.oreilly.com/product/0636920013471.do] for the book SQL Pocket Guide 3rd Ed.
I have downloaded the oracle vm/appliance for oracle 11g2 and I have started sqlplus as sysdba.
I'm feeling overwhelmed with these links describing how to create a database:
[http://www.adp-gmbh.ch/ora/admin/creatingdbmanually.html]
[http://tldp.org/HOWTO/Oracle-7-HOWTO-3.html]
[http://www.adp-gmbh.ch/ora/admin/creatingdbmanually.html]
(1) What is the command to list the existing databases?
(2) What is the command to delete an existing database?
(3) When creating a new database with the create database command, is it necessary to specify the logfile, character set, national character set, datafile, sysaux datafile, undo tablespace, temp table space? Do these have reasonable defaults? I'm not sure what proper directories are to specify for Linux and the examples are for windows.
Can someone give me a simplified create database command to create a database called 3rdEdPocketGuide? Should I follow the example at [http://tldp.org/HOWTO/Oracle-7-HOWTO-3.html] and instead of orcl use 3rdEdPocketGuide?
(4) What command do I use to execute the script that comes with the book SQL Pocket Guide 3rd Ed? This is the script that has all the drop table, create table and insert commands in it.
(5) What command do I use in sqlplus to set the current default database prior to running this script? Perhaps this is the connect command? I don't want my script to create tables in the system database.
(6) I tried the command "connect 3rdEdPocketGuide" and it prompted for a password! Yikes! What password? Do I need to specify a password when I create a database? I cannot tell if I have successfully created such a database or it is just prompting me for a password to thwart malicious users. Is it is possible to create databases which don't require a password or maybe a zero length password?
Thanks
Siegfried

Anyway, I'm trying your suggestion to use SQL Developer which was already installed in the virtual box appliance and I cannot figure out how to get a connection.
When I use the defaults of sid=xe, port=1521, hostname=localhost and specify

I get status: failure - test failed: listener refursed connection with the following error: ORA 12505, TNS: listener does not current know of sid given.
So I try sid=orcl and that works better: status: failure - test failed: ORA-01017: invalid username/passowrd; login denied
OK, sqlplus let me in with out a password, why does not this work?
So I try checking the box for "OS Authentication" and I get the same error!

Everyone:
Do I need to create a user using SQL*Plus first so I can login with "Oracle SQL Developer" so I create my database called? What would be the "create user" command I would execute?
OK, so I run sqlplus and issue these commands
create user siegfried identified by abc ;
grant connect to siegfried ;
connect siegfried/abc;
Now, how do I create a database? In Microsoft SQL Server one has to create a database first and if you just start creating tables without creating a database first, the tables will be created in the system database and this is usually undesirable.
Sometimes a database is known in the java connection string as the catalog. Is there any such analog in oracle SQL plus?
So now what do I do? I want to create a bunch of tables using my script I downloaded from 3rd Ed SQL Pocket Guide. Does my new user "siegfried" have the right to create tables? I guess I could try but I don't want to create tables in the system database.
I noticed I can also use "Oracle SQL Developer" to connect with my new "siegfried" account. It seems that I should have been able to connect with sysdba... strange.
So now I am connected in the "Oracle SQL Developer" and I see no list of databases.
Thanks!

In ecatt - how to check at database level using ABAP

Hi,
How to check at database level using ABAP in Ecatt tool.
say,for example I want to check a particular sales order is invoiced or not ,at the database level and if it is invoiced I have stop proceeding to invoicing of that sales order number.
Could anybody suggest on this with an example?
thanks.

Hi,
you can use the command GETTAB to access single db records.
Full specified or partitial specified keys can be use at GETTAB. It will return always only one record, also if a couple could match your selection.
For more advanced scenarios you can also use eCATTs Inline ABAP. In a block between the commands ABAP. ENDABAP. you can code ABAP statements, e.g. SELECT ... INTO TABLE ...
eCATT script parameters of type 'V' defined in that script using ABAP/ENDABAP will be transfered into the ABAP block and back to script after ABAP perform.
Best regards
Jens

How to clone Boot Camp partition when Winclone does not work

The hard drive in my MacBook Pro is failing. It has 2 partions, one for Apple and the other is a Bootcamp with Windows 7.
I tried repairing it with Disk Utility, which did not work. I also ran DiskWarrior, which resulted in the error message: "Directory cannot be rebuilt due to disk hardware failure". I was able to copy my Apple files through DiskWarrior although there were a couple of errors.
My question is how to clone my Bootcamp Partition. I tried making an image with Disk Utility but it failed. I also tried using Winclone and it failed indicating there were hard drive issues.
Is there another way to try to copy the Bootcamp partition? I can boot to Apple so running a program/app or trying UNIX commands might work.
Thank you in advance.

Some previous forum comments I have collected regarding backup of BootCamp.
Acronis 2011 w/ plus pak, didn't work well previously
Ghost 15 - probably not
Casper 6 works for Windows on Boot Camp only
CopyCatX is more lengthy and sector copy so takes the longest.
Paragon Hard Drive Suite 2011 because it works great and they have CampTune
Windows 7 system backup and restore - Apple's goofy HFS read-only interferes with system and file backup.
I have also used Casper, Clonezilla and Paragon but less regularly, Casper failed a few times, I stopped using it, Clonezilla worked but took forever (for me) Paragon (which I have only used twice) was the best but my sample is limited.
I have restored from DU, CCC, SuperDuper and TM, they all worked, TM was slower but not a lot, you can boot from the others, which I prefer.
Paragon HDM 2011 can do either offline or online backups, the difference is that with an offline backup, the entire partition (or disk) is unallocated. In an online backup, the backup utility is running against a partition that may be making changes to itself. When you run CCC or SD! in OS X, you're running an online backup. However, I would recommend (at least for the first backup) that you boot from the HDM recovery CD to do an offline backup. This will ensure that you have an *exact* copy of the parition/disk.
I tried the native Windows backup utility. It worked to backup and restore my Windows partition, but I noticed a "bad" side effect. When I would restore a Windows Backup to my HD, it would corrupt my MacOS boot partition, so I would then have to restore the Mac partition as well.
Winclone allows you to migrate your Bootcamp partition from one Mac to another Mac and make sure Windows will boot. However, if the processor (for example, Core Duo or i7) is a different type, the restored version of Windows may not be supported or be able to run on the new Mac. If you are migrating between Macs that are the same type (MacBook Air to MacBook Air, for example), you will have the greatest chance of success. You can try to restore Winclone images between different types of Macs (for example, a Mac Pro to a Mac Mini), but be aware that if Windows boots but does not reach the desktop, it is probably not an issue with Winclone, but rather the change in processor type.
