Export of Databases - reads data by running a select statement of the data and generating the DDL to perform the import process in future.
Fast Exports
1) Use direct=y
2) Until disk is not fully utilized try running exports in parallel.
3) Keep export file on different disk then the datafiles.
4) Run exports in two part rather than one i.e. 1st rows=n and second as indexes=n rows=y constraints=n.
Fast Imports
1) Use the first file out of two files created with the exports, It will insert all data but will not create any indexes and constraints. Once the data insertion is done run imp with indexfile option to extract script of index creation in text file. edit the file to include parallel clause and set parameters db_file_multiblock_read_count to 128 with sort_area_size to a higher value and workarea_size_policy=AUTO.

How Schema can be exported and imported in Oracle Apex?

Hi,
I am very new to oracle apex. I had installed Oracle XE database and apex successfully. I want to import an application to my apex. The application was created using workspace -Ver and Schema- Ves. I had imported the application and workspace into my apex. But, I am not able to run the application because, I had specified my default schema(HR) for the application. How can I import the schema 'Ves' ,in which the application is developed, into my apex?..so that I can run the application in the same schema..Please Help. Thanks

ThanksI am concerned that perhaps you and Jeffrey are working at cross purposes here. If you wouldn't mind confirming a few things first:
1. You make references to "import[ing] the application and workspace into +my+ apex - how many instances of oracle/apex do you have?
2. You say that you "specified [your] default schema (HR) for the application." I am assuming that you are referring to the "parsing schema"? If so, you can change this you know - it isn't 'set in stone' at the time you install.
3. With the above in mind, does the schema "Ves" exist at all in the 'target' Oracle instance /apex installation? If so, it may not be necessary to re-create it.
If you really do require to export/import the "Ves" schema, bear in mind that the DDL script will only create the schema objects - it won't load the data with it; you'll need to do that separately (or at least, code that element yourself into the script, if it's on the same DB instance). This might not be a problem for you but if your app relies on metadata from look-up tables and the like, it may not behave the way you expect, or even run at all...

Exporting and importing table using R3trans program between 2 clients

Hi,
How to export and import a table between to clients in a same system using R3trans program?
I need to copy a table from Client 020 in a system to client 040 of the same system using R3 trans. I need to know the procedure.
Can any one advice
Regards,
Suresh

This is how you do a export and import of table entries.
Export:
Open Notepad and type the following,
export
client = 020
file = 'clone.export.<sid>.<client no>.data'
select * from <client_dependent_tablename1>
select * from <client_dependent_tablename2>
select * from <client_dependent_tablenamen>
Save the file as export.ctl
Run R3trans export.ctl
and the data of these files will be stored in a file called clone.export.<sid>.data in the directory from which you have called R3trans
Import:
Open Notepad,
import
client = 040
file = clone.export.<sid>.<client no>.data
buffersync = yes
Save the file as import.ctl
Run R3trans import.ctl
Cheers!

hi,frank
thank you.
You know a page include a .jspx file,a page definition file and depend faces-config.xml,faces-config.oxd_faces and other I don't know information,so if i only put the first two file into cvs,but how can i get other information in the last two file?When I get the first two file and needed information in the other file,how can i merge these into new project and let jdeveloper "reconize it"?Applicaion is more complex,it not only depend its self java class,xml and many entity object and view object,how to handle the "export" and "import" process?Just like oracle form,only a fmb is enough,database object only need to "put into database","export" and "import" are very simple,so i need jdeveloper to supply these "import" and "export" function.I'm not familar with cvs,does it can know object dependency like application module?if it can,how to let jdev "reconize" imported in object?

How to export and import dependent tables from 2 different schema

I have a setup where schema1 has table 1 and schema 2 has table2. And table 1 from schema1 depends upon table 2 from schema 2.
I would like to export and import these tables only and not any other tables from these 2 schemas with all information like grants,constraints.
Also will there be same method for Oracle 10g R1,R2 and Oracle 11G.
http://download.oracle.com/docs/cd/B12037_01/server.101/b10825/dp_export.htm#i1007514
Looking at this For table mode it says
Also, as in schema exports, cross-schema references are not exported
Not sure what this means.
As I am interested in only 2 tables I think I need to use table mode. But if I try to run export with both tables names, it says table mode support only one schema at a time. Not sure then How would the constraints would get exported in that case.

How to export and import complete organization structure?

Hello,
I wanna import many (maybe 300) organization XML ObjectGroups in the right order.
I tried something like that (see the code below),... but this solution only works for one file.
<?xml version='1.0' encoding='UTF-8'?>
<!DOCTYPE Waveset PUBLIC 'waveset.dtd' 'waveset.dtd'>
<Waveset>
<ImportCommand name='include' file='c:/import/org001.xml'/>
<ImportCommand name='include' file='c:/import/org0011.xml'/>
<ImportCommand name='include' file='c:/import/org002.xml'/>
</Waveset>I tried to use wildcards like *,%,... the result is an error message :(
e.g.
file='import/org001*.xml'/>Has anyone experiences with that case?
There are an another way to export and import complete organization structure in IDM 8.x ?

Hi, Since you are using an program to transform the org structure to XML file,
why not write another program, just to generate the including list?
Then import from the file?

How to export and import "Computer Groups" and "Patch approvals" in WSUS 4.0 ?

Hi,
I have a query regarding the export and import options for "Computer Groups" and "Patch Approvals" in WSUS 4.0.
In WSUS 3.2 once we install WSUS 3.0 API Samples and Tools, we get "WSUSMigrationExport" and "WSUSMigrationImport" tools under
C:\Program Files\Update Services 3.0 API Samples and Tools\WsusMigrate\ folder.
Using the 'WSUSMigrationExport' tool we can export the Computer Groups and the Patch Approvals in a XML file. And using the 'WSUSMigrationImport' tool we can import the 'Computer Groups' and the 'Patch Approvals' from that XML file into a different WSUS
3.2 server. We can run the import tool as below:
a. Run command prompt as administrator.
b. In the command prompt, go to C:\Program Files (x86)\Update Services 3.0 API Samples ans Tools\ WsusMigrate\WsusMigrationImport
c. Type WsusMigrationImport filename.xml TargetGroups None. Press enter; this will import Computer Groups to the WSUS 3.2 server.
Type WsusMigrationImport filename.xml Approvals None. Press enter; this will import "Patch Approvals" to the WSUS 3.2 server.
This is easy and useful.
Now, for WSUS 4.0 I did not find "WSUS
4.0 API Samples and Tools". So I installed "WSUS 3.0 API Samples and Tools" in my WSUS 4.0 server. And tried to import a valid XML file in the above mentioned process. But the command returned an error.
The error says the "Microsoft.UpdateService.Administration.dll" file was not found.
I further searched in the internet about this issue and I found that the "WSUS 3.0 API Samples and Tools" is not supported in WSUS 4.0 as the .net framework used in "WSUS 3.0 API Samples and Tools" is 2.0 and WSUS 4.0 uses .net Framework
4.5.
So, Here are my questions.
1. Is it correct that "WSUS 3.0 API Samples and Tools" is not supported in WSUS 4.0?
2. Is "WSUS 4.0 API Samples and Tools" available?
3. Is there any alternative way in WSUS 4.0 to export and import XML file consisting "Computer Groups" and "Patch Approvals" configurations?
I need an urgent reply. Thank you in advance.

Hi Tapojyoti,
>>1. Is it correct that "WSUS 3.0 API Samples and Tools" is not supported in WSUS 4.0?
Yes, WSUS 3.0 API Samples and Tools is not supported in Windows Server 2012R2 by default. We may try to rebuild it in Windows Server 2012R2. For detailed information about how the rebuiled, please refer to the readme document of the WSUS 3.0 API Samples
and Tools.
>>2. Is "WSUS 4.0 API Samples and Tools" available?
No, I can't find the WSUS API Samples and Tools for 2012R2.
>>3. Is there any alternative way in WSUS 4.0 to export and import XML file consisting "Computer Groups" and "Patch Approvals" configurations?
As I have mentioned above, due to WSUS 3.0 API Samples and Tools is released with source code, we can try to rebuild it in the Windows Server 2012R2.
If it doesn't work, as a workaround, we can configure the new WSUS server as the replica server of the existing WSUS server. After the synchronization, change the server mode to stand alone.
Best Regards.

Hi!
You can also use ALTER TABLE MOVE command, or if you are on 9i you can use DBMS_REDEFINITION package.
If you have a maintainance window the easiest way would be to use alter table move.

How I can Export and Import tables using BRTOOL ?

Dear All,
Since we upgrade the oracle from 9.0.2 to 10.2.2 we not using SAPDBA any more.
please help me if you now how to export and import tables in sapr3 using brtools?
thanks and Best regards,
Chrisna

Dear Chrisna,
first of all you should get the recent version of the BRTOOLS (currently it's BRTOOLS 7.00 (<b>26</b>)). The developers are working hard on making these tools more reliable and usable so you should not deny the improvements to yourself.
Now to your problem:
Try this call:
brspace -f tbexport -o SAPR3 -t SSF_PSE_D,SSF_PSE_H,HTTPURLLOC
You don't need to specify a tablespace; it's just a additional option to select what tables you like to export.
