Data moving between Oracle 10g with CLOB fields

Hi all,
I have a trouble in migrate data between Oracle 10g with different platform. The worst thing is that I don't have a DBA account for the DB importing data. I think I can't use IMP or IMPDP in this way. So I seek help from sql developer, but it seems having another problem with CLOB data moving.
Re: EA2 : SQL Developer 1.5 : export data CLOB columns
in the thread, I found someone wrote this:
- SQL Developer v1.5 EA2 - exports first 4000 chars (which is anyway too small for me, because my CLOBs are larger - if they were smaller, I would have made them VARCHAR2s instead!).
I would like to ask:
1, What SQL Developer v1.5 EA2 is? Is it the Data Modeling one?
2, How to export table data with CLOB with SQL Developer v1.5 EA2? Since 4000 chars is enough for me to use.
OR any other method to export CLOB but not IMP / IMPDP ?
Now I am using the spool of sqlplus to export CLOB.
Many thanks,

1. The EAs are Early Adapters, betas, so you should expect the same behaviour from the latest 1.5.4 production release.
2. Exports can be done with the Database Export tool, through the table's context menu in the navigator tree or the result grid's context menu.
Have fun,
K.

Using Oracle Text with CLOB field containing multiple languages

I'm using Oracle 10g (NLS_CHARACTERSET is set to. AL32UTF8) and have a table with a CLOB field which is storing text written in either English and/or Simplified Chinese.
The following index has been created on this field:
CREATE INDEX text_index
ON text_table(text_field)
INDEXTYPE IS CTXSYS.CONTEXT
PARAMETERS('FILTER CTXSYS.INSO_FILTER');
I'm having issues in returning text which matches the Chinese text using the CONTAINS operator. For some reason the following query is returning rows which do not contain any Chinese text:
SELECT *
FROM text_table
WHERE contains(text_field,'炫%') > 1;
A newsgroup user advised me to produce an explain plan using ctx_query.explain.
I created 2 explain plans, one which was searching the index for 'A%' and the other searching for the Simplified Chinese character '炫%'. The results for the first test were as expected whereby the values contained within the OBJECT_NAME field all began with the letter 'A'.
The second test however produced somewhat unexpected results. The OBJECT_NAME field this time contained various words, both English and Simplified Chinese. I could be wrong but it appeared to store every individual word in the CLOB field. Both tests produced different EQUIVALENCE rows, the first test was:
OPTIONS = Null
OBJECT_NAME = A%
Whereas the second test produced:
OPTIONS = (?)
OBJECT_NAME = %
Am I right in thinking the Simplified Chinese character is for some reason being converted to a '?' character?
Any help on this will be much appreciated.

As you're not specifying a lexer to use, it will use the BASIC_LEXER, designed for space-separated European-type languages. This won't work effectively with Chinese.
If you know which documents are Chinese and which are English, you can write this into a LANGUAGE column and use the MULTI_LEXER - this will allow you to specify BASIC_LEXER for the English texts, and CHINESE_LEXER or CHINESE_VGRAM_LEXER for the Chinese texts.
If you don't know the language, you must use either WORLD_LEXER (10g) or AUTO_LEXER (11g). These lexers will automatically determine the language of the documents and index them appropriately. In general. MULTI_LEXER will be faster and more accurate than either of the automatic alternatives.
When querying for Chinese characters you need to be very careful with your NLS_LANG settings. You need to make sure that the character set defined in NLS_LANG is the same as the character set from which you've pasted (or typed) the chinese characters.
The "?" in output usually just means "I don't know how to translate this character into your output character set". Sometimes it may appear as a reversed question mark.

Data Sync between ORACLE and SQLServer

Hi,
I would like to here the possible options for "Bi-Directional Data Sync" between ORACLE 10g (Enterprise Edition Release 10.2.0.4.0) and SQL Server 7.0 (7.00 - 7.00.961 Standard Edition on Windows NT 5.0 ).
Please let me know the available tools or any other addons.
thanks and regards,

Are you looking for transactional replication between Oracle and SQL Server? Take a look at Wisdomforce [DatabaseSync.|http://www.wisdomforce.com/products-DatabaseSync.html]
It can perform a [real-time change data capture|http://www.wisdomforce.com/products-DatabaseSync.html] of transactions from redo log files and apply them into Oracle or SQL Server

Getting table script using dbms_metadata.get_ddl, but with clob field

So, Oracle 11g R2..
I'm using dbms_metadata.get_ddl to get table scripts and it's working fine..
now, I have a table with clob field, and it's not working... I got an 'missing right parenthesis (ora-0907)' error...
I could paste a script that I got, but I don't think it makes any sense..
does anybody have some experience on using this package on clob tables?
tnx

this is script that I got... it's long, and it looks like it's not good

Problem to connect between Oracle 10g xe and VB2010 at Vista sp2

Introduction
Hi guys, good day... NEED RESCUE!! SOS!! Hmm.. i have trouble been 1 weeks trying connect between Oracle 10g xe and VB2010 on window vista sp2. Actaully im very new at Oracle 10g xe and VB2010 but i got a project is going to build up system database and i figure out Oracle 10g xe and VB2010 can use free so i just chows these appication to be my project. I been search around internet and there is several things i was found about the connection but i has try and tried still it wont work out.
Things i found and learned
Oracle
1. I have download Oracle 10g XE and installed in my windows vista sp2.
2. I notice the Oracle Developer Tools is needed for VB2010 (To add reference 'Oracle.DataAccess'). So i was downloaded ODT11beta and installed
3. I also edit TNSNAMES to following below:
OraDb =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = shin-PC)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = orcl)
4. My sqlnet like following below:
SQLNET.AUTHENTICATION_SERVICES = (NTS)
NAMES.DIRECTORY_PATH= (TNSNAMES, EZCONNECT)
5.I have try tnsping OraDB and its works.
6. I monitoring task manager and OracleServicesXE is running.
7. ora_dba is added in Group.
Problem in SQLPLUS
When i try connect SQLPLUS in cmd i get ERROR: ORA-12560: TNS:protocol adapter error.
i . In cmd i type sqlplus and enter then i been ask for username and password.
ii. After i insert my username and password and enter then i get the error of ORA-12560.
Visual Basic 2010
1. First i created my project, drawing label and button for test connection.
2. Then, i add reference Oracle.DataAccess into my project.
3. I type following script into my vb form:
Imports System.Data
Imports Oracle.DataAccess.Client
Imports Oracle.DataAccess.Types
Public Class Logon
Private Sub cmdLogon_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles cmdLogon.Click
Dim oradb As String = "Data Source = OraDb; User Id = system; Password = shin;"
Dim conn As New OracleConnection(oradb)
conn.Open()
Dim cmd As New OracleCommand
cmd.Connection = conn
cmd.CommandText = "select SName from Staff where SName = shin"
cmd.CommandType = CommandType.Text
Dim dr As OracleDataReader = cmd.ExecuteReader()
dr.Read()
lblOra.Text = dr.Item("SName")
conn.Dispose()
End Sub
End Class
Problem in VB2010
When i run my project and press the button i get error message ORA-12514: TNS:could not resolve the connect identifier specified at conn.Open()
Extra Question*
1. Im notice in my netbook xp home sp2, before i install ODT11beta my sqlplus look fine thought cmd but after i installed ODT11beta its same problem with my Vista sp2 now. Get error ORA-12560: TNS:protocol adapter error :( I tried uninstall ODT11beta again and restart its work fine again. Which i really dun understand. Izzit the version ODT11 is not suitable for 10g xe? And i dunno this problem is related with my connection between oracle 10g xe and vb2010 or not. So confuse@@
2. I wish to know more about connect between Oracle and VB, is there still a things i miss?(I mean steps or configuration that should i done)
3. Or i just lower my VB version could make more easy? If yes, what version VB should i use that could work out with oracle 10g xe?
4. Sorry for too bad my english but i really wish somebody could help me. Please try to understand my written or you could ask me mean if dont understand. Im stuck!! Stuck feel not really that good.....

Huhu..
Yo, henry
I thought the OraDb is just a name for entry but im not sure it is a service. I was refer http://www.oracle.com/technology/pub/articles/cook-vs08.html at topic Connection Strings and Objects.
Here is my lsnrctl service

Izzit ok? I notice there is no listed OraDb. but tnsping OraDb seem fine.
Actually there is somethings as a newbie i wondering long time alreadly ><
1. The origin of tnsname.ora is no OraDb or ORCL but i just simple add it by open tnsname.ora with notepad. Im just not sure it is function or not.
Also please check at my TNSNAME.ORA:
XE =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = shin-PC)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = XE)

OraDb =

I got the feeling there is so close~~~!!!

Oracle Data Provider for Oracle 10g

We have an application certified on the ODP 9.2.0.2102, Oracle Client and Oracle ODBC 9.2.0.6. We have a client who is moving to Oracle 10g client within the next few months but will still be hitting an Oracle 9.2 backend.
My question is: Is the 9.2.0.2102 ODP compatible with the 10g client, or do we need to certify against a newer version of the ODP? And if the latter, what version of ODP is recommended?
We plan to certify against the latest of both this year, but for now, we need the path of least resistence.
Thanks for your help.

It is not "hard" to create your own geocoding schema though you will need to know how to create tables (with Oracle Spatial columns) in Oracle and before you do create the tables you should read through the documentation to be certain you have all of the required data and metadata.
Navteq, a data provider, also has sample geocoding data (http://www.oracle.com/technology/products/spatial/htdocs/spatial_partners_data.html) as well as data for sale. Downloading and importing the Navteq data might give you a good idea about what you will need to do if you were to build your own geocoding schema using your data.
I hope this helps.

Understanding logminer results -- inserting row into table with CLOB field

In using log miner I have noticed that inserts into rows that contain a CLOB (I assume this applies to other LOB type fields as well, have only tested with CLOB so far) field are actually recorded as two DML entries.
--the first entry is the insert operation that inserts all values with an EMPTY_CLOB() for the CLOB field
--the second entry is the update that sets the actual CLOB value (+this is true even if the value of the CLOB field is not being set explicitly+)
This separation makes sense as there may be separate locations that the values are being stored etc.
However, what I am tripping over is the fact the first entry, the Insert, has a RowId value of 'AAAAAAAAAAAAAAAAAA' which is invalid if I attempt to use it in a flashback query such as:
SELECT * FROM PERSON AS OF SCN #####' where RowId = 'AAAAAAAAAAAAAAAAAA'The second operation, the Update of the CLOB field, has the valid RowId.
Now, again, this makes sense if the insert of the new row is not really considered "+done+" until the two steps are done. However, is there some way to group these operations together when analyzing the log contents to know that these two operations are a "+matched set+"?
Not a total deal breaker, but would be nice to know what is happening under the hood here so I don't act on any false assumptions.
Thanks for any input.
To replicate:
Create a table with CLOB field:
CREATE TABLE DEVUSER.TESTTABLE
        ID NUMBER
       , FULLNAME VARCHAR2(50)
      , AGE NUMBER
      , DESCRIPTION CLOB
       );Capture the before SCN:
SELECT DBMS_FLASHBACK.GET_SYSTEM_CHANGE_NUMBER FROM DUAL;Insert a new row in the test table:
INSERT INTO TESTTABLE(ID,FULLNAME,AGE) VALUES(1,'Robert BUILDER',35);
     COMMIT;Capture the after SCN:
SELECT DBMS_FLASHBACK.GET_SYSTEM_CHANGE_NUMBER FROM DUAL;Start logminer session with the bracketing scn values and options etc:
EXECUTE DBMS_LOGMNR.START_LOGMNR(STARTSCN=>2619174, ENDSCN=>2619191, -
           OPTIONS => DBMS_LOGMNR.DICT_FROM_ONLINE_CATALOG + DBMS_LOGMNR.CONTINUOUS_MINE + -
           DBMS_LOGMNR.COMMITTED_DATA_ONLY + DBMS_LOGMNR.NO_ROWID_IN_STMT + DBMS_LOGMNR.NO_SQL_DELIMITER)Query the logs for the changes in that range:
SELECT

Scott,
Thanks for the reply.
I am inserting into the table over a database link.
I am using the new version of HTML Db (2.0)
HTML Db is connected to an Oracle 10 database I think, however the table I am trying to insert data into (via the database link) is in an Oracle 8 database - this is why we created a link to it as we couldn't have the HTML Db interacting with the Oracle 8 database directly due to compatibility problems (or so I've been told)

Need help for SQL SELECT query to fetch XML records from Oracle tables having CLOB field

Hello,
I have a scenario wherein i need to fetch records from several oracle tables having CLOB fields(which is holding XML) and then merge them logically to form a hierarchy XML. All these tables are related with PK-FK relationship. This XML hierarchy is having 'OP' as top-most root node and ‘DE’ as it’s bottom-most node with One-To-Many relationship. Hence, Each OP can have multiple GM, Each GM can have multiple DM and so on.
Table structures are mentioned below:
OP:
Name                             Null                    Type
OP_NBR                    NOT NULL      NUMBER(4)    (Primary Key)
OP_DESC                                        VARCHAR2(50)
OP_PAYLOD_XML                           CLOB
GM:
Name                          Null                   Type
GM_NBR                  NOT NULL       NUMBER(4)    (Primary Key)
GM_DESC                                       VARCHAR2(40)

I am using above SQL select statement for fetching the XML records and this gives me all related xmls for each entity in a single record(OP, GM, DM. DE). Output of this SQL query is as below:
Current O/P:
<resultSet>
     <Record1>
          <OP_PAYLOD_XML1>
          <GM_PAYLOD_XML1>
          <DM_PAYLOD_XML1>

     </Record1>
     <Record2>
          <OP_PAYLOD_XML2>
          <GM_PAYLOD_XML2>
          <DM_PAYLOD_XML2>

          <DM_PAYLOD_XMLN>
          <DE_PAYLOD_XMLN>
     </RecordN>

Now i want to change my SQL query so that i get following output structure:
<resultSet>
     <Record>
          <OP_PAYLOD_XML1>
          <GM_PAYLOD_XML1>

          <DE_PAYLOD_XML2> .......
          <DE_PAYLOD_XMLN>
     </Record>
     <Record>
          <OP_PAYLOD_XML2>
          <GM_PAYLOD_XML1'>

Appreciate your help in this regard!

Hi,
A few questions :
How's your first query supposed to give you an XML output like you show ?
Is there something you're not telling us?
What's the content of, for example, <OP_PAYLOD_XML1> ?
I don't think it's a good idea to embed the node level in the tag name, it would make much sense to expose that as an attribute.
What's the db version BTW?

How can we do the data migration between Oracle Applications and SAP R/3.

Hi All,
How can we do the data migration between Oracle Applications and SAP R/3 system.What are all the possible ways to move bulk data from Oracle Apps to SAP r/3 system.
Provide any 3rd party tools which supports data migration and also pls rpovide the SAP's own data migration tools with supports the above feature.
Awaiting for best possible solution.
Thanks in advance.
Regards
Dharmaraju

the 3rd party tool is ETL , you can use ETL tool and the prepare the load files then you can use LSMW method to upload the data to SAP.

How we create new data base in oracle 10g express edition

hello every body.. i student of B tech n new user of oracle so please help me how we creat new data base in oracle 10g express edition

Hello, Oracle XE can not create more than one instance, the other editions yes, but like other editions XE allows you to create database schemas, schemas logically grouped objects like tables, views, indexes created by a user. By creating an Oracle user is associated with a schema of the same name.
Using SYS or system accounts for creating user accounts.
Syntax to create a user:
create user Your_user
IDENTIFIED BY password
default tablespace users;
grant connect, resources to your_user;

Important differences between oracle 10g and 11g

Hi friends, can anyone tell me (pointwise) what are the major (and minor) differences between Oracle 10g and 11g.
Please point me to some documents if possible.
Thanks in advance

The name of the link says it all: "top_features."
In short it is Oracle's list of what they have for marketing and sales reasons designated "top features."
It is not intended to be, and is not, a complete list of features. Often the features Oracle does not
talk about are the most important.
Let me give you some examples. I have never seen Oracle announce DBMS_XPLAN as a new feature
yet you should not run an explain plan without it. Neither have I ever seen Oracle announce the new
NO_DATA_NEEDED predefined exception. I have listed literally hundreds of new features you will not
find in Oracle's new features docs.
I did a presentation at OpenWorld this year as part of the unconference titled "New Features in
Database 11gR2 that Oracle will not announce." It was easy to prepare a one hour presentation with
little fear of being proved incorrect. As I turned out only one of the features I presented was mentioned
by Oracle.
You can find the presentation slides here:

Is it possible to perform network data encryption between Oracle 11g databases without the advance security option?

Is it possible to perform network data encryption between Oracle 11g databases without the advance security option?
We are not licensed for the Oracle Advanced Security Option and I have been tasked to use Oracle Network Data Encryption in order to encryption network traffic between Oracle instances that reside on remote servers. From what I have read and my prior understanding this is not possible without ASO. Can someone confirm or disprove my research, thanks.

Hi, Srini Chavali-Oracle
As for http://www.oracle.com/technetwork/database/options/advanced-security/advanced-security-ds-12c-1898873.pdf?ssSourceSiteId… ASO is mentioned as TDE and Redacting Sensitive Data to Display. Network encryption is excluded.
As for Network Encryption - Oracle FAQ (of course this is not Oracle official) "Since June 2013, Net Encryption is now licensed with Oracle Enterprise Edition and doesn't require Oracle Advanced Security Option." Could you clarify this? Thanks.

Two problems in BSBM benchmark of Oracle 10g with Jena Adaptor 2.0

Hi, all.
I'm proceeding BSBM benchmark for Oracle 10g with Jena Adaptor 2.0.
I'm using the codes that were introduced in Jena Adaptor 2.0 guide document, and I've applied Jena patches to Oracle 10g (10.2.0).
But, two problems are occured in benchmark process.
The first problem is
     that 250k dataset(consisted of 250030 triples) loading time elapses over several hours, (See below code snippet.)
and the other is
     that exceptions are occured in some sparql query execution.
I used below queries which have no error in query syntax.
I confirmed that through other benchmark tests.
In case of oracle benchmark test, quey1 is ok. but, query2 makes exception.
Please, look about the Exception message below.
What should I do for getting much better benchmark result?
I appreciate any help or any hint.
Best regards ~

Hi,
The data loading was slow because incremental loading API was used. Please take a look at OracleBulkUpdateHandler. There is an addInBatch API that you can use.
Now regarding queries, Jena Adaptor v2.0 was primarily designed for Oracle Database 11g Release 1.
Recently, a new version of Jena Adaptor has been released and it's optimized for Oracle Database 11g
Release 2.
Is it possible to run your BSBM benchmark tests against Oracle Database 11g Release 2 using the latest
Jena Adaptor (http://forums.oracle.com/forums/ann.jspa?annID=1179) ?
Thanks,
Zhe Wu

Data source from Oracle 10g problem

Dear Sir,
We met a problem when we moved on Oracle 10g from Oracle 9i in the loading process. The scenario is that SQL Server as Data Warehouse, SSIS as ETL tool. But the length of string column as data source table in SSIS grows up 4 times when using Oracle 10g. For example, ABC table x varchar2(8) --> x varchar(32) -->x varchar(8) --> x varchar(8) {Oracle 10g SSIS(source) }
This doesn’t influence the loaded result (I did not find any problem until now), but that influence loading performance and we worry about potential problems.
Do you have any idea or have you met the same problem before? Is I need setup some parameters like "code page"
Thanks,
Jacob

You could try General Database Discussions the main db foum.
What are you using to migrate your database? Why is it being mapped from varchar2(8) to varchar2(32). It sounds like someone/something is intervening here.

Compare Oracle 10g with Teradata

hi.
How can we compare Oracle 10g with teradata under warehouse environments. While looking at Teradata the biggest advantage they are showing is that Teradata can support a very very big database and support Far better query support than oracle also oracle is design for oltp processing. But i am not able of find any technical papers regarding this claim.

AFAIK, Teradata uses hash-based indexes to do their work. Oracle centers around B-tree indexes. Each class of index has a specific group of problems that it solves extremely well - based on the type of query as well as the size of the data set.
Teradata demonstration teams will deliberately demonstrate the queries that perform better than on other systems, and will gleefully point at how much better they are than the others.
Oracle, DB2 and SQL Server tekkies will do the same.
This is one of the reasons why an intelligent customer will benchmark with their own applications. Another reason for running your own benchmark is that all major licenses tend to include a paragraph saying that benchmarks may not be published without approval of the vendor. So any benchmark that show Teradata better than Oracle will probably not get Oracle's approval. And vice versa. Unless the relevant marketing departments have an answer.
IMO, there are two considerations to think about:
1) There is proof that Oracle, DB2 and Teradata run extremely well in the world's largest warehouses, which exceed 100 TB. (Google the web for 'worlds largest database warehouse'). In general, one will be the leader in size and performance for a few weeks, then another will flip into that position ... such are the joys and benefits (to us) of competition.
So ... does your proposed warehouse come anywhere close to those sizes.
2) There are special skills needed to keep extremely large warehouses running. Those skills are no longer commodity skills, are tailored to the specific warehouse, and require both the individuals (plural) and the company to invest in long term relationship, including training.
So ... is your organization prepared to invest in, and support those special skills?
If the answer to either question is 'NO' then I submit that you are dealing with a commodity warehouse and the decision is not as much a technical one as 'which vendor provides you the most comfort'!
