Importing a few Oracle 10g schemas into oracle 11g database

Hi,
I have the task to import a few schemas that are on oracle 10g database (10.2.0.4) into oracle 11gR2 database (11.2.0.2). Now I have only oracle 10g export and import utility (the 11g server is in not where I am given the import rights).
Can I do the export of the 10g schemas using the 10g export utility and then import into 11g database using the 10g import utility? I ran a test to do that and found it works but would also like to have expert opinion on it.
Also another question is: if the source schema is 11g - suppose- in that case can the 10g export/import utility still work? I mean export the schema from say db1 (which is 11g) using 10g export utility and import them into 11g database db2 (which is again 11g) using 10g import? I am asking because I don't have access to 11g server and trying to find what I can do with the 10g utilities.
Thanks,

set up a database link to the 10gR2 version database in the 11gR2 database.
Now using the 11gR2 client impdp utility use
impdp network_link=<link to 10gR2 database>
Done.
Your 'objection' you don't have access to 11gR2 doesn't count as you can install a 11gR2 client.
Also generally speaking you should not use a lower version imp to imp to a higher version database
Also exp and imp are deprecated in 10g and higher.

How can i import tables from a different schema into the existing relational model... to add these tables in the existing model? plss help

how can i import tables from a different schema into the existing relational model... to add these tables in the existing relational/logical model? plss help
note; I already have the relational/logical model ready from one schema... and I need to add few more tables to this relational/logical model
can I import the same way as I did previously??
but even if I do the same how can I add it in the model?? as the logical model has already been engineered..
please help ...
thanks

Hi,
Before you start, you should probably take a backup copy of your design (the .dmd file and associated folder), in case the update does not work out as you had hoped.
You need to use Import > Data Dictionary again, to start the Data Dictionary Import Wizard.
In step 1 use a suitable database connection that can access the relevant table definitions.
In step 2 select the schema (or schemas) to import. The "Import to" field in the lower left part of the main panel allows you to select which existing Relational Model to import into (or to specify that a new Relational Model is to be created).
In step 3 select the tables to import. (Note that if there are an Foreign Key constraints between the new tables and any tables you had previously imported, you should also include the previous tables, otherwise the Foreign Key constraints will not be imported.)
After the import itself has completed, the "Compare Models" dialog is displayed. This shows the differences between the model being imported and the previous state of the model, and allows you to select which changes are to be applied.
Just selecting the Merge button should apply all the additions and changes in the new import.
Having updated your Relational Model, you can then update your Logical Model. To do this you repeat the "Engineer to Logical Model". This displays the "Engineer to Logical Model" dialog, which shows the changes which will be applied to the Logical Model, and allows you to select which changes are to be applied.
Just selecting the Engineer button should apply all the additions and changes.
I hope this helps you achieve what you want.

Hello Kalyan,
A couple questions:
1. Once you installed the 11G database, you did start the database services, yes?
2. Do you have a properly configured TNSNAMES.ORA file that points to your database?
3. You created a database that you are using and can access the database via SQLPlus?

What should i do with an Oracle 11g Database, MySQL database and a dump file.

I just joining to a new work field, almost about a database and i know "NOTHING" about this field.
My company has a system that running by Oracle Database, the problem is that Oracle Database will cost a lot of money when my company expands.
So the quest is converting Oracle Database to MySQL database.
Of course i cant try to convert it in the main Database, so i create one Oracle 11g Database on my LocalHost, and it already actived in " Localhost:1158 " etc.
I have another Sever test that already set up MySQL database, and a dump file from the system.
So I want to ask these 2 questions :
1. How to create an new Oracle Database from that dump file ?
2. Is it alright if i use tool to convert Oracle Database into MySql, or i should do it manually ?
Thanks alot.

So the quest is converting Oracle Database to MySQL database.
I predict that converting to MySQL will cost your company more as it expands. As you expand managing contention becomes more important - Oracle does this for you. I do not think MySQL does, so you'll have to write more code to deal with this, costing the company money. A big part of making application scalable and reliable is to use stored procedures, how good are MySQL's compared to PL/SQL's. What other features are there that MySQL has that will benefit your company that Oracle doesn't. What do you need to think about as your company expands that need to be taken care of in the database. I would have thought a migration from MySQL to Oracle would be more common to deal with expansion.
As you know "NOTHING" you need to think about what each database can give you for the next 10 years to cope with you businesses potential requirements, and extimate how much it will cost to implement these requirements, then make the decision

Oracle 11g database stores CAS number incorrectly in chemical database.

Hi,
I have an issue in Oracle 11g database. I am working on a chemical database which handles chemical structures ,formulas, CAS numbers, ACX number. The database has a compound table which stores compound attributes like chemical structure, molecular weight, CAS number and so on. The CAS number is of type varchar2(15) and will be in the format 50-50-0. All the CAS numbers will be in this format.
The issue which I found specific to Oracle11g database is that when a CAS number is edite and saved from the application it changes into some random characters like AEAAAA8AA in the table. With Oracle 10g version there were no issues. Can anyone please help me to understand what could be the reason for this? Looking forward to your replies on this.
Thanks

What are the privileges required for explain plan in Oracle 11g database

I am facing the problem in doing a explain plan for a view in Oracle 11g database. When I select from the view like this:
select * from zonewisearpu
It does a select on the view but when I give explain plan like
explain plan for
select * from zonewisearpu
I get the error like insufficient privileges.
Please let me know if things are getting missed out as I guess system level privileges are required to execute this.
I hope, my question is clear.
It’s a humble request to revert urgently if possible as I need to complete a task and do not know the way out.

Thanks for your reply. I have found out that an explain plan is possible on the user's own objects and is not possible on the granted objects from a different schema. For eg, if I do a explain plan on a view querying on tables from a different view, it would not allow the explain plan to proceed. This could mean that explain plan needs different privileges than just a select.
Requesting for a revert to this.
Here is a simple test case that I have perfomed
SQL> create user test1 identified by test1;
User created.
SQL> create user test2 identified by test1;
User created.
SQL> grant connect, resource to test1,test2;
Grant succeeded.

Conencted.
SQL> show user
USER is "TEST2"

SQL> explain plan for

So, as can be seen I am able to do a explain plan from user test2 for tables belong to user test1.
As far as privileges are concerned, following is the list

Telling us that you are using 11.1 helps. But it is far from a complete description of the environment. What edition of the database are you using? What options are installed? What Enterprise Manager packs are licensed? Is any of this changable? Could you license another option for the database or another pack for Enterprise Manager if that was necessary?
What does it mean to you to "mask data"? Do you want to store the data on disk and then mask the data in the presentation layer when certain people query it (i.e. store the patient's social security number in the database but only present ***-**- and the last 4 digits to certain sets of employees)? Do you want to hide entire fields from certain people? Do you want to change the data stored in the database when you are refreshing a lower environment with production data? If so, do you need and/or want this process to be either determinisitic or reversable or both?

Oracle 11g database installation

Hello,
I just want to install the oracle 11g database system in my Archlinux. I've looked the wiki but it's a little bit old.
So has someone tried these days installing it in Arch? How is it going? And the AUR script works?
Another question is how mush size it will be when installed?
Thanks!

I have successfully installed Oracle 11g R2 using the instructions in the Dutch article on the wiki: https://wiki.archlinux.org/index.php/Or … erlands%29 (Google translate is useful).

Oracle 11g database link to Oracle 8

Hi,
database-links from an Oracle 11g to an Oracle 8-Database seem to do not work:
The error in enterprise manager is: socket error (translated from german).
There are no alerts at the Oracle 11g-Database.
On the other (Oracle 8) side, the alert we have is an "internal error"
Has anybody else that experience, and maybe a solution?
Thx a lot for your help

Oracle 11g Database Prerequisites Check Failed

hi all, i need to install the oracle 11g database on my D drive but the check was failed where the check take place in C drive. Therefore, i just skipped it.
