What does "select * from nls_database_parameters" return on the two machines?

Hi mick57,

If you're on Linux or Unix, you can use the dbca tool in graphical mode. It's a "Wizard" that will help you create an empty database.

Quite simple and quick. You'll find it under $ORACLE_HOME/bin

Good luck.

Dave

export you mean ???

import:
something (file, etc.) => oracle

export:
oracle => something...

Are you torn between Linux and Windows?
Do you want to spend time or money?

Hello

I want to know what the syntax is for importing an Oracle database
and whether the entire structure of the database will be imported or not

Thank you

Hello everyone,

I am importing from an Oracle 9i database to a 10g one, and the import starts correctly, with some tables being created properly. However, after a certain time, I get the following message:
IMP-00017: Failed to execute the following statement with ORACLE error 6550:
"BEGIN SYS.DBMS_EXPORT_EXTENSION.SET_IMP_SKIP_INDEXES_OFF; END;"
IMP-00003: ORACLE error 6550 encountered
ORA-06550: Line 1, column 12:
PLS-00302: Component 'DBMS_EXPORT_EXTENSION' must be declared
ORA-06550: Line 1, column 8:
PL/SQL: Statement ignored

Do you have any idea what the source of this error could be?

Importing an export from a base 8 into a base 9i is possible. The reverse is not (basically you can upgrade but not downgrade).

However, BATMAT is right; it's a problem related to the CHARACTER SET that is defined at the creation of the database and cannot be changed afterwards.

It is not possible to import a database with a "higher" character set than the database into which you want to import it. (Basically, if your original database has "à" or "é" while the one you are importing into does not recognize these characters: it's dead!).

So: recreate the 9i database.

There might still be a solution: use tr to excess. I've never looked at the format of Oracle exports: if the format is simple and uncompressed, you could do something like

tr 'àâéèê' 'aaeee' < yourExport > tmp
mv tmp> yourExport

I'll check on Monday if it's possible and I'll try to let you know what it is... Unless someone announces that the Oracle export format is pure binary, compressed, encrypted, or whatever ;p

I just checked and the export leaves the data in plain text... So it must be possible to use tr.

To be tested then :)

Thank you,
it's true that when it comes to a higher character set, it's not possible to do the import,
so the solution is to reinstall 9i carefully, choosing the appropriate character set, and it was done successfully. Additionally, it should be mentioned in the import script that the FULL option must be set to YES.

Thank you all.

Hello,

I am looking for how to import only the data from an Oracle database and I do not want to import the table structures.

Thank you

Pour importer/exporter une base de données Oracle dans Unix, vous pouvez utiliser les outils suivants :

1. **Exportation :**
Utilisez l'outil `exp` ou `expdp` (Data Pump Export) pour exporter les données de la base.
Exemple de commande avec `expdp` :
```bash
expdp username/password@dbname directory=dir_name dumpfile=export_file.dmp logfile=export_log.log
```

2. **Importation :**
Utilisez l'outil `imp` ou `impdp` (Data Pump Import) pour importer les données dans la base.
Exemple de commande avec `impdp` :
```bash
impdp username/password@dbname directory=dir_name dumpfile=export_file.dmp logfile=import_log.log
```

Assurez-vous que le répertoire spécifié (`dir_name`) a été créé dans Oracle et que l'utilisateur a les permissions nécessaires.

Please, every time I install Oracle 9i, OMS cannot start.

I have tried several times, and I have not succeeded. What should I do?

That is to say, how do I install Oracle 9i with OMS?

Hello,

I'm also looking to migrate from Oracle 8i to 9i.
No problem with the export.

However, how do I create an empty database on 9i to import into a clean database?

Thank you

Micka

Hi and thank you for your response davlar99.

Actually, I'm on Windows.
I managed to create my empty database. I created the tablespace and the rollback segments like the existing 8i database.

I also created the role and the user with which I am doing the export.

The import is going "not too badly," but there are errors with the statistics:

IMP-00017: The following instruction failed with Oracle error 6550:
"DECLARE SREC DBMS_STATS.STATREC; BEGIN SREC.MINVAL := '31'; SREC.MAXVAL := "
"'393939'; SREC.EAVS := 0; SREC.CHVALS := NULL; SREC.NOVALS := DBMS_STATS.N"

".SET_COLUMN_STATS(NULL,''xxxx,'ICODE',NULL,NULL,NULL,,,00000"
"1111111,0,srec,4,0); END;"
IMP-00003: Oracle error 6550 encountered
ORA-06550: Line 1, column 367:

The symbol "null" was substituted for "," to continue.

Do you have any idea?

Thanks</an>

Hello,

This is a known bug from Oracle since 2005.

Most often, it's because there is an apostrophe somewhere in the name of a column.
So there are either 2 possibilities: the NLS are not the same (DB to DB) or (in the registry or environment variable) or
it's either the apostrophe issue.

In the case of the apostrophe:
I took the time since to export (in 9i) with the option statistics=none
The option might also exist with the import command (never tried).
I know that the ANALYZE=N option exists but does it do the same thing?.

In the case of NLS:
Compare your registry parameters or those of your DBs in the v$NLS_PARAMETERS table.

Cheers!

Bonjour, merci
Je veux l'instruction pour importer la base de données sous Oracle, j'ai la sauvegarde .BMP ? Merci.

Hello,
I want to know how to create a database in Oracle 8i and get its name and path because I want to use it in a Java program, and then how I can import it onto a CD.
Thank you in advance.

Hello, please I need Oracle courses for my practical work regarding the management of TP rooms
Thank you in advance.
