Transferring Data between Databases with Character Sets UTF08 and US7ASCII

Hi,
I am trying to transfer data from Oracle 10g (character set :UTF08) to Oracle 8i ( character set: US7ASCII). I have tried the transfer using the DBLinks and found that there is no way the data could be transferred from 10g to Oracle 8i.
The last option available is to use staging database for transfer. The staging database would be Oracle 10g only but the character set would be US7ASCII. I am expecting that since the character set is US7ASCII, this would be able to get compatible with Oracle 8i (US7ASCII). Secondly, Transfer from 10g to staging 10g should also work, since staging 10g would support UTF08 character set.
Kindly tell me if this option would work or if there is any other way around.
Thanks
Nitin

You possibly have a fundamental problem,which is more important than any technical issues. If your UTF8 (Unicode) database stores non-english characters you will lose these characters when transferring.

It seems good
but if we input
http://127.0.0.1:8080/apex
it shows
HTTP Status 404 -

description The requested resource () is not available.
Sun Java System Application Server Platform Edition 9.0

Yes, Apex is almost entirely independent of the file system. There is no 'Apache' and the 'file system' is really the database exposed as a WebDAV environment.
If I understand the question correctly, what you want to do is export from the original database and import to this one. That may be done using the 'exp' and 'imp' commands at command line.
Details of advanced use of exp and imp are available in the Utilities manual found in the 10g Release 2 docco at http://www.oracle.com/pls/db102/portal.portal_db?selected=1 (under the 'Books' tab).

Can a db with character set UTF8 be restored to AL32UTF8?

Hello Everyone,
Good Day.
Our present production and non-production databases are configured with NLS_CHARACTERSET as UTF8. However, as we are in the process of migrating to a new server, we intend to configure the new databases with NLS_CHARACTERSET as AL32UTF8 (which is the recommended option as per our research. Moreover, came to know that for Weblogic schemas and repositories to work, NLS_CHARACTERSET must be AL32UTF8).
As we would be restoring from a backup to the new instance created on the new server, kindly help us understand if any issues might arise while restoring due to both being different charactersets?
Warm Regards,
Vikram.

Hi Robin,
Thank you for the update. Our DB is too huge and contains many schemas to try for a data pump. Hence we had planned for a restoration which might be simpler task with lesser downtime.
Perhaps, one option would be to create the instances with UTF character set itself and then change it once the migration activity has been completed.
Also, could you please throw some light on the two character sets as to which one is better and why?
Warm Regards,
Vikram.

Problem with character set UTF-16 LE

Hello.
There were difficulties with character set change, using function convert ()
The matter is that in the list v$nls_valid_values the character set AL16UTF16LE does not appear, during too time the inquiry is successfully carried out
convert ([some-national-characters], ' CL8MSWIN1251 ', ' AL16UTF16LE ').
But at giving on an input of the data stored in CLOB, there is an error "a character set is not supported"
What are possible ways of the decision of a problem?

You can try to use DBMS_LOB. SUBSTR to access LOB data like in the following example:
SQL> select * from v$version;

NLSRTL Version 10.2.0.1.0 - Production
SQL>
SQL> declare
2 v_i clob;
3 v_o clob;
4 begin
5 v_i := 'a';
6 v_o:=convert(dbms_lob.substr(v_i,1,1),'AL16UTF16LE', 'CL8MSWIN1251');

There is something incompatible would be my guess. Did you disconnect all your peripherals in safe mode just to check?
You might now create a new temporary user account. Log into the new account. Do the panics still occur?
I would also visit The XLab FAQs and read the FAQ on diagnosing kernel panics. Sometimes they can be difficult to track down. Looking at each new panic log would help determine if it's cause is associated with the same extensions.

Transfering tables between databases

I have some tables in an Oracle database that I have to copy (for tests) to another Oracle database resident on another computer without compromising the first database in any way.
How can I do this? Is there a friendly (and straightforward process) ?

Hi,
Apart from the three methods what Mr.Lijesh Kalavara has stated, i feel COPY command can be another option.
It copies data from a query to a table in a local or remote database location.
Set arraysize and set copycommit controls the transactions commit batch mechanism.
sql> SET ARRAYSIZE <Number Of Records in each batch>
set arraysize 1000 determine the 1000 records of the total records will be retrieved in each batch.
sql> SET COPYCOMMIT <Number of batches should be commited at one time>
set copycommit 1 indicates one batch should be commited at a time.
So if we are inserting 100,000 records then data will commit after inserting 1000 records every time.
If you have a small rollback segment , set arraysize to less number of records and copycommit to 1.
Syntax :-
usage: COPY FROM <db> TO <db> <opt> <table> { (<cols>) } USING <sel>
<db> : database string, e.g., scott/tiger@d:chicago-mktg
<opt> : ONE of the keywords: APPEND, CREATE, INSERT or REPLACE
<table>: name of the destination table
<cols> : a comma-separated list of destination column aliases
<sel> : any valid SQL SELECT statement
Append : - Create table in the destination if it does not exist and ignore if it exist and insert rows
Create :- Create table in the destination and insert rows
Insert :- insert the rows only . Error occurs if the table does not exist.
Replace :- Drop the existing destination table and creates new table with data.
e.g.
set copycommit 100 arraysize 1000 buffer 100000
COPY FROM schema1/password@Db1 TO schema2/password@db2
insert table_in_db2 (column1, column2) USING SELECT * FROM table_in_db1;
COPY supports the following datatypes:
CHAR
DATE
LONG
NUMBER
VARCHAR2
By using copy command you can reduce the burden on a rollback segment by dividing the entire inserting data into pieces or batches which commit individually and thus avoid of using large rollback segment.

Transforming the Raster Data between Databases

Hi
I have a Requirement to Import and Export The Raster Data Between Data bases .. Could Any Body Give Me Hint...
Rajanikanthc

NedimAT pointed you to the 10g manual. If your database is 11g, please check it out from the 11g manual, Section 3.21 Transferring GeoRaster Data Between Databases:
http://download.oracle.com/docs/cd/E11882_01/appdev.112/e11827/geor_operations.htm#CIHECFGC
Depending on your requirements and the source and target database environments, you may also consider using Transportable Tablespace to transfer the raster data, particularly when you want to transfer only part of the database based on queries or cropping areas. Check section 3.22:
http://download.oracle.com/docs/cd/E11882_01/appdev.112/e11827/geor_operations.htm#CHDGEGHB
hope this helps

Problem with character set - Reports 11.1.1.4

Hi!
I have a problem with Oracle Reports 11g regarding character set configuration. The default character set WE8ISO8859P1 works, so PDF reports have a regular display except for Eastern European (EE) letters which are replaced by "¿" sign.
So, when I set any other character set in reports.sh, which would be a normal step to get EE letters, I'm always getting Greek Alphabet in PDF reports. Why Greek Alphabet?
The character sets I tried to use are: EE8ISO8859P2, UTF8 and AL32UTF8.
I changed uifont.ali and included PDF Subset with all four Arial font variants and, of course, I placed all fonts in fonts folder which is pointed by REPORTS_FONT_DIRECTORY.
In Reports Builder everything works fine, but when I have to deploy the report to the Reports Services, the problem occurs.
Also, when I've tried to execute PDF report using In-Process Reports Server (rep_wls_reports_hostnameasinst1) instead of AS Instance Reports Server (RptSvr_hostnameasinst1, which is a regular server), I'm getting Greek Alphabet in PDF reports even if the default character set is WE8ISO8859P1 in reports.sh. What is wrong with it? Where is Greek Alphabet configured?
The production environment is 64-bit Oracle Linux 5.6 with Weblogic 10.3.4 and Forms&Reports 11.1.1.4. Forms works fine with character set EE8ISO8859P2 defined in default.env file.
Thanks in advance!
Regards,
Dejan

Thank you, Denis!
Doc 300416.1 was very useful but Note 356221.1 - A Practical Methodology on Porting Reports from Windows to Unix with Different Font is actually crucial for configuring Reports on Linux.
Also, there is a bug in 11.1.1.3 and 11.1.1.4, which can be fixed using the patch ( Note 1138405.1 - PDF Reports With Font Subsetting Raises Error "Bad /Bbox" on 64-Bit Linux ).
Kind regards!

What are the alternate methods of transferring data between apps built on ios

Hi All,
What could be the alternate methods of transferring data between apps built on ios?
Please comment.
Thanks
Pankaj

I'm not aware of any apps that can open pdfs from iBooks, but I could well be wrong. There are a small number of apps that will open pdfs from emails, you can also open pdfs from some applications ike dropbox which has an iOS app so you can access any document you can open on iOS and sync between devices and computers.
Sorry if this is all a little vague, I'm not exactly sure what it is you are asking

Clarification on Character set migration from US7ASCII to UTF8

Hi,
I need clarification on the below.
I need to migrate the database from US7ASCII to UTF8.
For this I ran csscan for user "TEST" as well as against full database.
Below log is the csscan output against full database. but my application is depended on TEST schema only. Shall I need to migrate SYS objects data as shown below or it's not required?. If required how to migrate these objects data?
Looking forward you help.
USER.TABLE Convertible Exceptional
SYS.METASTYLESHEET 58 TEST.Table_1 9 0
TEST.Table_2 11 0
TEST.Table_3 17 0
TEST.Table_4 11 0
[Distribution of Convertible Data per Column]
USER.TABLE|COLUMN Convertible Exceptional
SYS.METASTYLESHEET|STYLESHEET 58 0
Thanks,
Sankar

I think you need to migrate all schemas data not only one application schema because
the database character set is common to all CHAR, VARCHAR2, LONG and CLOB colums
for any tables in any schema.
In your case (US7ASCII to UTF8), you need to use export/import because:
Another restriction of the ALTER DATABASE CHARACTER SET statement is that it can be used only when the character set migration is between two single-byte character sets or between two multibyte character sets. If the planned character set migration is from a single-byte character set to a multibyte character set, then use the Export and Import utilities.

Difference between Req with insufficient lead time and lead time const

Hi ,
1) Can anyone explain the difference between Requirement with insufficient lead time and Requirement lead time constraint exception messages. Both seems to be similar for me with the compressed time.Also at what situations these exceptions are generated.
2) what is minimum lead time required ,actual lead time and its calculation.
Thanks...

Transport tablespaces between databases with different character sets

Hi everyone:
I have two 10R2 databases on the same hp-ux 64bit server, 1st one with NLS_CHARACTERSET=US7ASCII, 2nd one with
NLS_CHARACTERSET=AL32UTF8.
NLS_NCHAR_CHARACTERSET on both databases is AL16UTF16.
Can I transfer tablespaces from the 1st one to the 2nd. The data could be in English, French & Spanish.
If not what are my options?
Thanks in advance.

First off, if you are storing French and Spanish data in database 1 where the character set is US7ASCII, you've got some serious problems. US7ASCII doesn't support non-English characters (accents, tildes, etc). If you're storing data this way, you've introduced data corruption that you'd have to resolve before copying the data data over to another machine.
Second, technically, the source and target character set have to be identical. Since US7ASCII is a strict binary superset of AL32UTF8, you could theoretically transport a US7ASCII tablespace to an AL32UTF8 database. In your case, though, since the data is not really US7ASCII, you'd end up with corruption.
Any of the Oracle built-in replication options is going to require that you resolve the corruption issue. Assuming that you can figure out what character set the source database really is, you could potentially dump the data to flat files (taking care not to allow character set conversion to take place) and SQL*Loader them into the destination system by identifying the proper character set in your control file. That's obviously going to be a rather laborious process, though.

The solution to this problem is described in MetaLink note #211920.1. But this note is published with LIMITED access as it involves using a hidden parameter.
You can get access to the note through Oracle Support only.
The problem itself is solved generically, if the source database is at least 10.1.0.3 and the target database is 10.2

Transfering data between H.Planning applications

Hi all,
I would need some help with transfering (synchronizing?) data between two Hyperion Planning applications. The source application has less dimensions ( just 8) than the destination application (13 dimensions). And we know there is one of the source dimensions (Entity dimension) that determines which is the combination for more than one destination dimensions ( Responsable, Geography, Market...). Just to clarify:
Source Dimensions Destination Dimensions
1 AccountS -----------------------------> AccountD
2 ScenarioS-----------------------------> ScenarioD
8 EntityS--------------------------------> EntityD
EntityS--------------------------------> Responsable
EntityS--------------------------------> Geog.
EntityS--------------------------------> Market
Which would be the best way to solve that problem? I've been reading the EPMA Admin Guide ( Data Synchronizer), but I don't know how if that's the way to do it. How about Business Rules or Scripts?
Thanks for your ideas and support.

You can also you "partitioning" to do this. Old school method but if you understand it you can do exactly the mapping you are displaying, including going from a cube with less dimensions to a cube with more dimensions. It's a bit tricky thought to get the syntax right but once set up will continue with you month over month. Based on your model it actually might be multiple partitions to make this work correctly.
Another idea is to use a secondary Alias table for the one for one mapping part. and go with John's method.
It also begs the question why your models are so different in the first place, if they share data, but I'm sure you have good reason for this.
