Hi All
I have a database on my NT server named "ndb". I have exported the entire database into a file using command....
exp system/manager file=ndb1 log=ndb1 full=y
Now I have to import it on my win2000 machine. On that machine I already have a default database. This exported database I have to set up as a new database. Please tell me what next I have to do. I know the following steps.. Please tell me whethere they are correct or not ....
1) I have to create a new ini.ora file first
2) then create a new sid with ORADIM utility and
3) set oracle_sid=ndb on command prompt
4) then import database using imp system/manager file = ndb1 log=ndb full=y ignore=y
Since I set oracle_sid=ndb on my machine which does not exist physically.. It does not recognise the system user. How do I do it. How can I create a new database out of the export file.
Thanks in Advance

Amol,
Creating the sid and an init.ora is not enough.
You need to create a database first!!
Try looking up the 'Create database' command.
Check out your documentation or training docs for information on how to do this.
Good luck!

Hi
I have run the create database script and gave the dbf and log files the same name as that of in earlier database . (Is it ok if I give different names ? ) Now do I need to run the catalog.sql and catproc.sql to created the database or will it be formed from import ?
Amol
-
you will need to run the scripts you mentioned yes.
-
you can create with a different name if you wish.
Yes, you must run catalog and catproc as sysdba before importing the full export as system.
You should make sure you log your import to a file.
ALSO - ensure that the tablespace creation commands will work - i.e. you have the same file paths available as the previous db and enough disk space.
If not you must pre-create your tablespaces.

Similar problem
Hi,
I have a similar problem. I exported a production database with option full=y.
I have a development and a test environment. I would like to import data from my exported file to these dev and test instances. The production instance is name DB_PROD. But the dev and test isntances are respectively DB_DEV and DB_PROD.
How can I import data form the export to these instances. They have the same table structures but different tablespaces.
Thanks,
Stevens

Hi,
Set the SID=to the database to be loaded into (DB_DEV or DB_TEST I presume)
If the tables already exist then setting the ignore=Y flag should ignore any create error messages. If the tables do not already exist then they will be created in the default tablespace of the user identified by the touser=username flag.
if the tables already exist in the database you may need to truncate them to remove any data within them. Then import the data for each users schema using the ignore flag set to Y
eg
imp system/manager file=exp.dmp log=exp.log fromuser=username touser=username ignore=y
Cheers

To important your DB, you have to create a database having the same structure (same tablespaces... So if you have 4 TS in you old DB, you have to create them in your new. The loaction or the number of file behind the DB don't matter).
Hope this helps

Situation where you have to replicate the database from EXPORT dump, IMPORT is 2 step process,
Prior to that, assuming you have Database and required Tablespace created,
Step 1:
imp system/manger file=EXPDAT.DMP INCTYPE=SYSTEM
Step 2:
imp system/manger file=EXPDAT.DMP INCTYPE=RESTORE
