Question

import_db

Asked by: sam15

I exported an 11g schema to 9ifile.dmp on a unix machine.
I installed 11g on windows and created a database APPS.
I ftp the file from unix to windows.

I want to import the file to APPS database.
 Do i need to create a schema first and issue some priviledges
or start the instance/database or etc? What tool you use for that.

I did c:> imp appadmin/appadmin file=9ifile.dmp full=Y

but it is not doing anything,

2. If i want to refresh the data every week do i dopr the schema nad import again. how do you do that?

>>but it is not doing anything,

No messages, errors whatsoever?


1) Instances must always be running for any logical tool like export or data pump to work.
2) Pre-create the schema user on the target database, and grant appropriate privileges, including enough privs to create the objects in the schema.

3) Since you are using 11g, I recommend using data pump (expdp/impdp) rather than export (exp/imp) because impdp has a "table_exists_action" parameter that you can set that will allow overwriting of existing data, or even drop-recreate of existing objects.

Try googling or EE search on "impdp table_exists_action"

 

by: sam15Posted on 2009-09-08 at 15:55:27ID: 25286878

no messages indeed.
so you go to sql*plus on the server and do
create user appadmin identified by appadmin;
grant connect to appadmin;

how can i grant dba_role to appadmin to ensure i have similar priviledges on account as 9i?

is OEM the only way to start the instances?

 

by: sam15Posted on 2009-09-08 at 16:03:24ID: 25286911

do i really need to read all of this to learn how to use OEM

It does not seem OEM is sinstalled as part of the server install. I looked for it and it is not there.
do i need to install the client package.

First of all, how did you do the export. Was it schema export or FULL export?

If you exported the schema only, then you will need to import using the FROMUSER and TOUSER parameters.

You will also need to create the user and tablespace for the data to reside befoe running import.

For a schema import try running

imp parfile=import.par

import.par --

USERID=appadmin/appadmin
BUFFER=5000000
FILE=9ifile.dmp
LOG=9ifile_imp_schema.log
COMMIT=Y
FROMUSER=<ENTER SOURCE SCHEMA USER HERE>                  - TOUSER=<ENTER DESTINATION SCHEMA USER HERE>

 

by: sam15Posted on 2009-09-09 at 05:27:52ID: 25290402

i did the export by schema. this is what i used.

exp appadmin/appadmin@myapp  file=myapp.dmp
imp appadmin/appadminfile=myapp.dmp  full=Y

Oracle told me that appadmin did not have right for the import since export was created by dba account.
I did it by system/manager. But i think i have to isse privieldges to appadmin on windows and then do the import. I will try FROMUSER like you said

 

by: probinson7Posted on 2009-09-09 at 05:53:23ID: 25290637

Import using system or an account with import full database privillage.

You can then do a schema based import using FROMUSER / TOUSER.

Just make sure you have created the user prior to import.

 

by: sam15Posted on 2009-09-10 at 03:18:13ID: 25298754

this is what i get after i run your statement. a few errors related to tablespace and compile. I thought i had all tablespaces similar. do i need to redo it. how do you verify all objects aere imported and import did not stop in the middle.

Have you created the tablespace USERDATA, the first error is saying it is unable to create the table as the tablespace does not exists.

I would drop the user with DROP USER <USER NAME> CASCADE;

Then reimport that data again.  Ensureing all tablespaces have been created first.

 

by: sam15Posted on 2009-09-10 at 15:20:53ID: 25305111

I did rename the tablespace from USERS to USERDATA.
I did the export from 9i using the appadmin account.
I did the import like you suggested using system account.

I see all tables getting imported fine and then a bunch of warnings on views
and then an audit DDL tigger/


If you compare the objects in 9i versus 11g they do not match. Does that mean import failed?
What do you suggest to do.

I made a mistake in the above list for 11g list of objects. I was logged in as SYSTEM instead of APPADMIN. Here is the list as APPADMIN user it seems number of objects matches. you think everything was imported fine.

The errors are only warnings, hopefully the view will recompile ok now that all the data is imported.

You need to run a recompile and check how many objects you have are invaild on both source and destination.

sqlplus "/ as sysdba"
@?/rdbms/admin/utlrp.sql

I would manually try and recreate the constraints if they don't exist.  Also check that the table they are referencing exist.

The import has worked as it has imported sucsessfully.
