Retrieval of xmltype data from oracle 10g to java

Hi
Right now we are facing an issue on xmltype retrieval from oracle 10g to java.
I used xmltype column.getClobval() to get the xml content, but unable to do the parse to get the xml data.
So i tried getStringval(), getting the xml content as string format and here in this case also, i didn't get document object.
Here is the code snippet:
String sql = "SELECT node_id,node_desc,parent_node_id,e.report_xml.getStringval() FROM TABLE_STRUCTURE e";
st = con.createStatement();
rs = st.executeQuery(sql);
while (rs.next()) {
Object value[] = { rs.getString(1), rs.getString(2), rs.getString(3), rs.getString(4) };
list.add(value);
DOMParser parser = new DOMParser();
parser.parse(rs.getString(4));
doc = (Document) parser.getDocument();
System.out.println(": DOM = " + doc.getClass().getName());
Please do guide in this scenario.
Thanks in advance.

Retrieve specific range data from oracle table

Hi, Dear friends,
I want to retrieve all the data from oracle table and then save them to mysql table using JDBC ResultSet. The problem is that some oracle table is too big, if I retrieve all of them to memory at a once time using excuteQuery, the program will become no response out of memory limitation. So my question is if I can retrieve just specific range data once a time. I can¡¯t find this function through JDBC API. Also, I don¡¯t want to use the specific sql sentence, for example ¡°select ¡ from¡ where someid>¡ and someid<¡¡±, because there are many different tables, I want to transfer them automatically. So I can¡¯t construct such sql sentence in advance. Does anyone know if oracle JDBC driver provide such kind of function or does there any other way?
Any suggestion will be greatly appreciated!
Sammy

Dear Justin,
thank you so much for your prompt reply!
as your suggestion, I do check the performance while my program is running, after the program become nearly no response, I found the memory usage is nearly 100%, while disk usage and process usage is pretty low. that's the reason why I guess maybe the memory limitation, but the strange thing is that no any error reported by JBuilder, it just nearly no response and don't transfer any data any more. my os is windows xp, the version of JBuilder is 7. my main memory is 768M. just as you said, the total 6,000 records in not very large, just no more than 400K. another strange thing is that why my program works well when there is little data records in the table.
the big picture of my program is first I retrieve oracle table metadata, according to this information, I construct DDL sql words and then create the corresponding table in mysql database. this part works well. in order to save your time, I will not paste the code here. then there is a method to transfer oracle data to mysql table, whenever creating the mysql table, then I will call this method to transfer datat to it. the following is the code of this method, I am very sorry to take your time. please read it when you are available.
thank you very much!!
Sammy

Exporting Data From Oracle 10g to Access

Hi Experts,
I need to export data from oracle apps shcema(each and every object in it) to MS ACCESS File.
Please let me know how to do it
Thanks and Regards,
Andy

Since you did not provide details of what you are planning to do, a very simple, however, depending upon the number of your tables, very labour intensive solution:
Although being not very familiar with access, I think access offers a means to import csv files.
So e.g. using SQL*Plus you can execute the following steps.
set pagesize <nnn>
set linesize <nnn>
set colsep ',' -- You may choose other special characters to separate columns of your output
spool <csv-file>
select * from <tab>;
spool offWherever you see <nnn> exchange by appropriate numeric values to get just one page as result and to configure your line size to hold a complete record in one output line.
Replace <csv-file> and <tab> by the name of your output file to be read in to access and by the name of your table, respectively.

Export Data from Oracle 10g and import in SQL server

Hi Guys,
I have assigned a task in which I am required to transfer data from oracle database to SQL server. I have not done this before. Can anybody help me the easiest way to accomplish this. Thanks

One way of doing this is setup Heterogeneous Database connections

I am sure there's other options out there.

Problem with retrieving data from Oracle 10g / PHP4.3 / Apache 1.3.27

Hi,
I re-open a new thread following the opened post 'Getting RPMs for php-oracle for PHP4.3 on RHEL 4.0 and issue with OCI8 '
I could re-installed PHP4.3 and apache 1.3.27 from the normal tar package (./configure then make) - I had some issues with the RPMs packages before.
I could connect successfully PHP4.3 to my Oracle 10g DB with no issues by using some of the (deprecated) functions contained in oracle.so library in command line mode by executing a simple PHP script ;-)
But ...when I try to execute the same script (a simple log on to the DB) or the application throught my web browser there are some errors in the apache error_log file that crash the process:
[Wed Jul 25 13:19:23 2007] [notice] child pid 25450 exit signal Segmentation fault (11)
[Wed Jul 25 13:19:31 2007] [notice] child pid 25451 exit signal Segmentation fault (11)
*** glibc detected *** realloc(): invalid size: 0x08338898 ***
[Wed Jul 25 13:19:42 2007] [notice] child pid 25441 exit signal Aborted (6)
*** glibc detected *** realloc(): invalid size: 0x08338898 ***
[Wed Jul 25 13:54:52 2007] [notice] child pid 25508 exit signal Aborted (6)
[Fri Jul 27 04:39:56 2007] [notice] child pid 20550 exit signal Segmentation fault (11)
After some investigations it looks like this is due to the connection of Oracle 10G and php.
I tried to recompile Apache as the following:
# cd /usr/src/apache_1.3.xx
# make clean
# LIBS=-lpthread ./config.status
# make
# make install
but the issue is the same ...
How can I workaround that issue and fix it in order to connect to Oracle 10 G by using PHP4.3 / apache 1.3.27 ?
I need to use the oracle.so library to avoid to re-rewrite all my application ...
Any help much very appreciated !
Cheers
Dominique

You are in unchartered territory. But check the common "gotcha" and
make sure that all the Oracle environment variables are set in the
shell that starts Apache. Load the script <?php phpinfo(); ?> in a
browser and see that whatever variables you need are set in the
Environment section. See the section "Oracle Environment Variables
for Connections" in Underground PHP and Oracle Manual
I suspect it would be beneficial to migrate the PHP code to oci8.
Check table 16-1 in Underground PHP and Oracle Manual for the mapping
between 'oracle' and 'oci8' functions.

Help ! Cannot retrieve Object table data from Oracle 8i

Dear All,
Created the object and object table in SQL*Plus. If query from SQL*Plus, return rows selected.
But if query from SQL*Plus worksheet and ODBC Test program, return "0 rows selected".
Similary, if created the object and object table in SQL*Plus worksheet and query from SQL*Plus worksheet, return rows selected.
But if query from SQL*Plus or ODBC Test program, return "0 rows selected".
Appreciate advice from anyone. Thanks in advance.
Oracle version. 8i Enterprise Edition Release 2
Scrip to create object and insert record:
CREATE TYPE stockitem_objtyp AS OBJECT (
STOCKNO NUMBER,
PRICE NUMBER,
TAXRATE NUMBER
CREATE TABLE stock_objtab of stockitem_objtyp (stockno primary key) object id primary key;
INSERT INTO Stock_objtab VALUES (1, 1000, 3);
select * from stock_objtab;
null

First, I suspect that this question probably belongs on the ODBC forum, since it doesn't appear to be at all related to the JVM.
That said, I don't seem to have any problem retrieving the data, either through ODBC or SQL*Plus. If you post your question to the ODBC forum, perhaps some other folks will be able to try this and we can narrow down the problem.

Guide me for exporting and importing data from oracle 10g to oracle 9i

I have been trying export and import options in oracle but m not very clear about the procedure..
Also when i am logging in as Scott/tiger i am facing an error
ORA 1542 - tablespace 'USER' is offline and cannot allocate space in it.how to resolve it

Hello,
I see two questions.
ORA 1542 - tablespace 'USER' is offline and cannot allocate space in it.how to resolve it About the error ORA-01542 you have to bring the Tablespace USERS online:
http://www.error-code.org.uk/view.asp?e=ORACLE-ORA-01542
If you cannot bring it online you may have to Recover it first.
I have been trying export and import options in oracle but m not very clear about the procedure..About the Export in 10g and Import in 9i (9.2 or 9.0.1 ?), you have to export with the Export utility of the Target Database (the lowest Database version here: 9.0.1 or 9.2) then, you have to Import to the Target Database using its Import utility (in 9.0.1 or 9.2).
The following Note of MOS may guide you:
Compatibility Matrix for Export And Import Between Different Oracle Versions [Video] [ID 132904.1]
NB: You cannot use here the DATAPUMP.
Hope this help.

Migration using data pump Oracle 10g - Oracle 11g

HI all,
1)
Right now I`m using Oracle 11g. I have a plan to import data from Oracle 10g. I would like to know if its possible to import data which was exported by datapump on Oracle 10g ?
Should I convert somehow expdp output from Oracle 10g to Oracle 11g format ?
2)
Next question is. If I will use expdp to create dump of complete database. May I use *.dmp to import selected users ? Or only full database can be restored ?

Yes, you can import 10g dump into an 11g database.
Maybe you should take some time and read the section on datapump in the fine Oracle® [Database Utilities|http://download.oracle.com/docs/cd/B28359_01/server.111/b28319/dp_import.htm#i1007324] manual.

Hi John
Well i have working knowledge in ODI, i did whole complete cycle and i did customization project for Oracle EBS to Data warehouse though ODI.

Retrieve data from a large table from ORACLE 10g

I am working with a Microsoft Visual Studio Project that requires to retrieve data from a large table from Oracle 10g database and export the data into the hard drive.
The problem here is that I am not able to connect to the database directly because of license issue but I can use a third party API to retrieve data from the database. This API has sufficient previllege/license permission on to the database to perform retrieval of data. So, I am not able to use DTS/SSIS or other tool to import data from the database directly connecting to it.
Here my approach is...first retrieve the data using the API into a .net DataTable and then dump the records from it into the hard drive in a specific format (might be in Excel file/ another SQL server database).
When I try to retrieve the data from a large table having over 13 lacs records (3-4 GB) in a data table using the visual studio project, I get an Out of memory exception.
But is there any better way to retrieve the records chunk by chunk and do the export without loosing the state of the data in the table?
Any help on this problem will be highly appriciated.
Thanks in advance...

Girish...Thanks for your reply...But I am sorry for the confusions. Let me explain that...
1."export the data into another media into the hard drive."
What does it mean by this line i.e. another media into hard drive???
ANS: Sorry...I just want to write the data in a file or in a table in SQL server database.
2."I am not able to connect to the database directly because of license issue"
huh?? I never heard this question that a user is not able to connect the db because of license. What error / message you are getting?
ANS: My company uses a 3rd party application that uses ORACLE 10g. And my compnay is licensed to use the 3rd party application (APP+Database is a package) and did not purchased ORACLE license to use directly. So I will not connect to the database directly.
3.I am not sure which API is you are talking about, but i am running an application of the visual studio data grid or similar kind of controls; in which i can select (select query) as many rows as i needed; no issue.
ANS: This API is provided by the 3rd party application vendor. I can pass a query to it and it returns a datatable.
4."better way to retrieve the records chunk by chunk and do the export without loosing the state of the data in the table?"
ANS: As I get a system error (out of memory) when I select all rows in a datatable at a time, I wanted to retrieve the data in multiple phases.
E.g: 1 to 20,000 records in 1st phase
20,001 to 40,000 records in 2nd phase
40,001 to ...... records in 3nd phase
and so on...
Please let me know if this does not clarify your confusions... :)
Thanks...

Problem in importing data in oracle 10g from 9i backup

Hi ,
Am trying to import data in oracle 10g..but it does not importing constraints, and stop doing anything by the msg.
About to enable constraints.....
after this msg it does not work.
plz help,
Regards,
Neha

Hi Neha,
You have a lot of options. I'll supose you can test first, and you're using an export file.
First forget about the data, think in your database structure. So you can do this:
exp userid=... file=exp_norows.dmp full=y rows=n statistics=none
Now you have the structure of your database. Create the database, in 10g, empty, check you have all filesystem, etc. for you new datafiles. And do the import with parameter ignore=y, you'll see a lot off errors on SYSTEM schema, don't worry about it.
Now you have the structure of you database in 10g. You can take a look in the import log file, looking for some possible errors come from your schemas. so check the objects, and check the schemas.
Bear in mind things like CONNECT role in 9i it's different in 10g, you can't create db_links in 10g with "IDENTIFIED BY VALUES" because you'll get an ORA-00600, etc.
Well, fix all problems on source database (9i) and repeate this procedure until you don't recieve any more errors (not a SYSTEM schema errors).
When you have everything solved, you can try to import the data.
I hope, this method can help you. If you have any problem do not hesitate to ask me.
