Hi everybody,

i'm new at this Forum and i have a question about Transport tablespaces between Oracle 10g and 12c with the Standard Editions?
i read on Google that i can only use the Transport tablespace command within rman only with an Enterprise Edition.
So are there any other possibilities to Transport the tablespaces? Or is the only way an Schema user Export /Import?

so thanks a lot for help Smile

Transportable tablespaces are not available in SE. Do you want to transport tablespaces to existing database with data or brand new database? If latter, clone existing 10G database and upgrade it to 12C. But personally, for versions upgrades I prefer creating brand new shell database and using data pump to copy the data.

Hi Solomon,

thanks a lot for your help. that would be a brand new database in Oracle 12C. How can i do a data pump from Oracle 10 to 12c, especially from two tablespaces?

You can't do "from two tablespaces". You export/import schemas/objects.

why are you fixated on tablespaces?

How will we know when correct solution has been posted here?

Hi everybody,

the Job i have to do is following:
we have a document Management System which can connect to Microsoft SQL Server, Oracle, postgre and so on. one of our customer has an old Version of this program and we want to migrate this Version to the newest Version.
so i have an old Environment with w2k8, our old dms System and Oracle 10 with the character set WE8MSWIN1252. The new Environment is w2k12 r2, brand new Version of our dms System and Oracle 12c with character set AL32UTF8.
our dms System generates two schema-users.

first of all i did an Schema user Export / Import. When i do an Import i get the message: "import-Server uses character set AL32UTF8 (possible charset conversion)". So i don't know if i have any Problems or not.
a first check with the SQL developer to look at the tables seems to be ok, but i don't know exactly. So a colleague said i could try to Transport the tablespaces from the old Oracle10g, instead of create new tablespaces with the same Name in the new Environment with an Schema Import.

So how can i find out if my Import has worked correctly? So wenn a Schema user Export / Import is enough i don't force a tablespace Transport.
I hope you can help me.

AL32UTF8 is a superset of WE8MSWIN1252 so no problem will occur.

ok, perfect so i can do a schema-user Export/ipmort. Only for interest. Is it possible to do a rman full database backup under Oracle 10 and restore this Backup under Oracle12c?

When you do RMAN restore, you get a "cloned" copy of the source database; nothing more & nothing less.
If you do RMAN backup of V10, then the restored copy will also be V10.
You then could upgrade it to V12 as a separate operation.

ah ok and in this case the same Charakter set Wink in your post above you wrote that there will be no Problems with the different charakter set. I've done a test bevore i opened this thread with Oracle 10 and Oracle12c with the same Charakter set WE8MSWIN1252 and did the Schema user Export / Import. Next i changed the Charakter set in Oracle12c to AL32UTF8 with the two commands:

alter database character set AL32UTF8;
alter database character set internal_use AL32UTF8;

after that i saw an table entry changed with the letter รถ in an rectangle.
I don't know if i've done an other mistake or that we could say Schema user Export / Import from WE8MSWIN1252 to AL32UTF8 is no Problem, but the Change of an Charakter set with the alter commands could be a Problem?

That technique for changing characterset is unsupported and may destroy your database. Release 12.x comes with the Database Migration Assistant For Unicode (the DMU), and that is what you should use.

Before attempting the export/import you should have used the DMU to scan the source datbase for potential problems.

Hi John,

i tried the Migration Assistant but it means that my Oracle 10 is too old for a connection Sad Does it makes any sense to do the Schema user Import and scan the own database? I don't think so isn't it? Because this database is already Unicode...

This is plain STUPID!
What do you think INTERNAL_USE mean?

in this case i must say i'm new in Oracle and this two commands where found during Google search for my test environment.
But now i know it better and do the schema user export/import.

The last question for this szenario. Above we said an import between this charakter sets are no problem. But wenn i do an export the exp programm said:

Export done in US7ASCII character set and AL16UTF16 NCHAR character set
server uses WE8MSWIN1252 character set (possible charset conversion)


is this also no problem or should i do some more things in this case? For exp and imp i use the following commands:

exp system/<password> owner=<Schemauser> file=<name>.dmp log=<name>.log consistent=y
imp system/<password> fromuser=<Schemauser> touser=<Same Schemauser> file=<name>.dmp log=<name>.log

Of course it is a problem. You could be losing a whole load of characters.

First, stop using the old exp/imp utilities. Data Pump will do a better job.

It is not a question to be or nor to be new just to be a little bit smart and not blindly apply something found using Google search.
When something is named INTERNAL_USE you should think that this is not something to use before either Oracle itself tell you to do so or being an expert and knowing what that's implies.

@John
thanks for the tip. So i instruced my self in the syntax and it seems nearly the same. For the export it doesn't rant me for the charakter set like the exp command did it.
So is it important for the expdp and later impdp to do something, in my case with the two charakter sets WE8MSWIN1252 on Oracle 10 and AL32UTF8 on Oracle12c?
