Oracle hangs on CLOB indexing

Hello.
I use Oracle 8.1.7 at Solaris OS.
I have table with CLOB field. This field is indexed.
create index IDX_CLOB on QX_CLOB (DATA) indextype is ctxsys.context parameters('filter ctxsys.INSO_FILTER');
I tried to add records in this table from another and resync index, but system hangs on this operation. I found what is a problem. The problem is data which can not be parsed. System hangs when I try to filter problem record by this comand:
ctx_doc.filter('IDX_CLOB', 194, 'filtertab', 0, TRUE);
The problem record has plain text clob data.
Could anybody help me ?
Thanks,
Evgeny.

Are there any errors in the alert logs or any trace file for ora-600 generated?

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:

GM_NBR                  NOT NULL       NUMBER(4)    (Primary Key)
GM_DESC                                       VARCHAR2(40)

DM_NBR                  NOT NULL         NUMBER(4)    (Primary Key)

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>
          <DE_PAYLOD_XML1>
     </Record1>
     <Record2>
          <OP_PAYLOD_XML2>
          <GM_PAYLOD_XML2>
          <DM_PAYLOD_XML2>
          <DE_PAYLOD_XML2>
     </Record2>
     <RecordN>
          <OP_PAYLOD_XMLN>
          <GM_PAYLOD_XMLN>
          <DM_PAYLOD_XMLN>
          <DE_PAYLOD_XMLN>
     </RecordN>
</resultSet>
Now i want to change my SQL query so that i get following output structure:
<resultSet>
     <Record>
          <OP_PAYLOD_XML1>
          <GM_PAYLOD_XML1>

          <DM_PAYLOD_XML1>
          <DM_PAYLOD_XML2> .......
          <DM_PAYLOD_XMLN>
          <DE_PAYLOD_XML1>
          <DE_PAYLOD_XML2> .......
          <DE_PAYLOD_XMLN>
     </Record>
     <Record>
          <OP_PAYLOD_XML2>
          <GM_PAYLOD_XML1'>
          <GM_PAYLOD_XML2'> .......
          <GM_PAYLOD_XMLN'>
          <DM_PAYLOD_XML1'>
          <DM_PAYLOD_XML2'> .......
          <DM_PAYLOD_XMLN'>
          <DE_PAYLOD_XML1'>
          <DE_PAYLOD_XML2'> .......
          <DE_PAYLOD_XMLN'>
     </Record>
<resultSet>
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 to prevent Oracle from using an index when joining two tables ...

How to prevent Oracle from using an index when joining two tables to get an inline view which is used in an update statement?
O.K. I think I have to explain what I mean:
When joining two tables which have many entries sometimes it es better not to use an index on the column used as join criteria.
I have two tables: table A and table B.
Table A has 4.000.000 entries and table B has 700.000 entries.
I have a join of both tables with a numeric column as join criteria.
There is an index on this column in table A.
So I instead of
where (A.col = B.col)I want to use
where (A.col+0 = B.col)in order to prevent Oracle from using the index.
When I use the join in a select statement it works.
But when I use the join as inline view in an update statement I get the error ORA-01779.
When I remove the "+0" the update statement works. (The column col is unique in table B).
Any ideas why this happens?
Thank you very much in advance for any help.
Regards Hartmut

I think you should post an properly formatted explain plan output using DBMS_XPLAN.DISPLAY including the "Predicate Information" section below the plan to provide more details regarding your query resp. update statement. Please use the \[code\] and \[code\] tags to enhance readability of the output provided:
In SQL*Plus:
SET LINESIZE 130
EXPLAIN PLAN FOR <your statement>;
SELECT * FROM TABLE(DBMS_XPLAN.DISPLAY);Usually if you're using the CBO (cost based optimizer) and have reasonable statistics gathered on the database objects used the optimizer should be able to determine if it is better to use the existing index or not.
Things look different if you don't have statistics, you have outdated/wrong statistics or deliberately still use the RBO (rule based optimizer). In this case you would have to use other means to prevent the index usage, the most obvious would be the already mentioned NO_INDEX or FULL hint.
But I strongly recommend to check in first place why the optimizer apparently seems to choose an inappropriate index access path.

Queries on oracle hang after index creation

Hi,
I have a problem where queries issued on an oracle database hang after I create indexes on some of the tables used by these queries.
I have a script where I drop indexes :
DROP INDEX EVP_PCON00_CDSITC_IX;
DROP INDEX EVP_PCS202_STIMP1_IX;
DROP INDEX EVP_PECT00_ONAECT_IX;
DROP INDEX EVP_PVAL01_ONAVAL_IX;
After this script I load data into those tables.
Then I launch another script where I recreate the indexes I just dropped :
CREATE INDEX EVP_PCON00_CDSITC_IX ON EVP_PCON00(CDSITC) TABLESPACE TS_ODS_INDEX;
COMMIT;
CREATE INDEX EVP_PCS202_STIMP1_IX ON EVP_PCS202(STIMP1) TABLESPACE TS_ODS_INDEX;
COMMIT;
CREATE INDEX EVP_PVAL01_CDORIV_IX ON EVP_PVAL01(CDORIV) TABLESPACE TS_ODS_INDEX;
COMMIT;
When the script ends, I try to execute a query using some of the tables I created indexes on :
SELECT ...
FROM ....
WHERE ....
The query never return a result set, it just hangs, I look at the session browser in toad and the scan of the first table used in the query hangs.
When I drop those indexes and re execute the query everything works fine.
Thanks

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.

Sql Developer 3.0.04 hangs displaying CLOB data

I have two different Oracle instances.
First is Oracle9i Enterprise Edition Release 9.2.0.5.0 - 64bit Production.
Second is Oracle Database 11g Release 11.2.0.1.0 - 64bit Production.
Data have been exported and imported in the newest instance. With the same client Sql lDeveloper 3.0.04, I run a query on the same table (in both instances) containing a CLOB column I have different behaviour.
In the Oracle 9 instance the query returns the right data.
In the Oracle 11 instance the query hangs without a result.
Do you have any idea about this behaviour?
Thanks, Silvio.

Right, the query does not return any data.
1. Knowing that the query does not return any data, I got the dump just few seconds after I executed it.
2. I was opening the table with Object Viewer Data Tab.
below you will find a dump taken after 30 seconds I executed 'select * from .....' into SQL Worksheet with F5.
3. I am using the driver inside sql developer installation, I have Oracle 10g client installed but sa far as I know Sql Developer connect Oracle database by java driver.
4. I am running Sql Developer 3.1.06.44 with Java 1.6.0_11. For other purpose in my machine I have also Java 1.6.0_25.
Thank you for your replies.
Silvio.

Oracle Text - CTX Context Index Soundex Problem

Hi,
I'm running into a problem with Oracle Text when searching using the ! (soundex) option. I've created a simple test example to highlight the issue.
Oracle Database 10g Enterprise Edition Release 10.2.0.4.0 - 64bit
Windows 2008 Server 64-bit
create table test_tab (test_col varchar2(200));
insert all
into test_tab (test_col) values ('ab-tönes')
into test_tab (test_col) values ('ab-tones')
into test_tab (test_col) values ('abtones')
into test_tab (test_col) values ('ab tones')
into test_tab (test_col) values ('ab-tanes')
select * from dual
select * from test_tab
begin
      ctx_ddl.create_preference ('test_lex1', 'basic_lexer');
      ctx_ddl.set_attribute ('test_lex1', 'whitespace', '/\|-_+&''');
      ctx_ddl.set_attribute('test_lex1','base_letter','YES');
      -- ctx_ddl.set_attribute('test_lex1','skipjoins','-');
end;
create index test_idx on test_tab (test_col)
indextype is ctxsys.context
    parameters
      ('lexer        test_lex1'
select token_text from dr$test_idx$i;
TOKEN_TEXT
AB
ABTONES
TANES
TONES
select * from test_tab where contains (test_col, '!ab tones') > 0;
TEST_COL
ab-tönes
ab-tones
ab tones
select * from test_tab where soundex(test_col) = soundex('ab tones');
TEST_COL
ab-tönes
ab-tones
abtones
ab tones
ab-tanes
So my question is, can anyone suggest an approach whereby I can get the Oracle Text Context index (or CTXCAT index if it's more appropriate) to return all 5 rows like the simple Soundex is doing?
I can't really use soundex as this search query will form part of a search screen for a multi-language application. Soundex is limited to English sounding words, so I need the solution to be able to compare strings that may not "sound" English.
It must be an attribute of the BASIC_LEXER, and I've tried skipjoins, start/end-joins, stop lists, but I just cannot get the Soundex feature of Oracle Text to function like the SOUNDEX() function!
Looking at how the tokens are stored dr$test_idx$i I need Oracle Text to almost concat 'AB' and 'TONES' to search as a single string.
Any help greatly appreciated.
Thanks,

I am not getting the same problem that you are getting with the umlat, but I don't see what is different. Please post the result of:
select ctx_report.create_index_script ('test_idx') from dual;
Here are the results on my system. Perhaps you can spot the difference. I added an empty_stoplist, so that it won't print out a long list of stopwords.

Andy,
You appear to be working a problem one step ahead of our problem. Ourproblem
is how do you get data into a Clob in the first place?
If you could give us an example that works within WLS, we would greatlyappreciate
it.
Thanks,
Cully.

After more investigation and help from Daniel Hoppe (THANKS!), the

has been narrowed down to the jDriver/Oracle driver. Using the Oracle

Cannot convert type class java.lang.String to class oracle.jbo.domain.Clob

Cannot convert type class java.lang.String to class oracle.jbo.domain.ClobDomain.
Using ADF Business Components I have a JSFF page fragment with an ADF form based on a table with has a column of type CLOB. The data is retrieved from the database and displayed correctly but when any field is changed and submitted the above error occurs. I have just used the drag and drop technique to create the ADF form with a submit button, am I missing a step?
I am using the production release of Jdeveloper11G

Help - Inserting an XML document into a Oracle 8i Column (CLOB Type)

Hi JavaGurus,
I am looking for a simple java code which will take my XML document as input and insert the same into a Oracle 8i database's column which is of type CLOB.
Insert statement won't work and I can not use SQL Loader.
Any one?
JK

Maybe you can adapt some of the code in Oracle's "LOB Datatype" example, which is a complete working program that stores and retrieves BLOBs and CLOBs.

Oracle hangs on query with multiple joins

To test the sotftware from the LMS-vendor that are out partners we use virtual machines where we install Windows 2003 servers and Oracle XE
While we were testing the software I've found that a particular query with multiple unions causes the CPU of the virtual machine totally claimed by oracle
The query causes oracle to hang.
I've found that the subcomponents of the query all return 0 rows (and response all immediately) combined into a query with at least 2 unions the query hangs the system
I'm not familiar with with Database Management at all
I've read something about SGA and PGA that could be the issue and tried to increase the target for both but it doesn't seem to do anything
Some characterics

Some pointers, help would be appreciated.

Oracle 8i Function-based index

Hi,
i have problem with making Oracle8i to use function-based index. I am using version 8.1.6 Enterprise Edition.
So here is the test I did
CREATE INDEX first_name_index ON customer ( UPPER(first_name)) ;
alter session set QUERY_REWRITE_ENABLED = TRUE;
alter session set QUERY_REWRITE_INTEGRITY=TRUSTED;
ANALYZE TABLE customer COMPUTE STATISTICS;
alter index first_name_index compute statistics;
Everything seemed to be as required by Oracle but it doesn't use this function-based index when I make
select *
from customer
where upper(first_name) like 'J%';
I test it on large table and with table with few hundred rows. I don't have NULLs in that field.
Can anyone help me with this.

I would not create an index to have it prepared for an ORDER BY. An index is quite costly in DML opperations and space as well. More, a function based index will be costlier as the function has to be called for every read and/or write.
Do not forget that indexes a created for a direct access to data and not for sorting purposes.

OMWB 10.1.0.2 Ms Access to Oracle strange migration of Indexes

Hi
I am migrating from MS Access 2000 to Oracle 10g with OMWB 10.1.0.2 .
My Access source model has 123 indexes in it.
1.The Access source model is creating index for the same column of the same table and names it like ~~temp~index~name0 for some indexes
2.In some cases the index is created again in the source model for the same column of the same table with just the UNIQUE ,NON UNIQUE property differing.
3.Is it necessary to migrate indexex to oracle?
4.How the non-migration of indexes would affect the database performance?
Can anyone help me on this issue?
Thanks.

Hi Vinod,
To assist in resolving your issue, I would firstly recommend that you carry out the following steps on the MDB file you wish to export:
1. Analyze the objects in your .mdb file using the Documenter facility in Microsoft Access. From the menu bar, select Tools, Analyze, Documenter, and then select the objects (for example, tables or queries) for analysis. Remove or resolve any erroneous objects.
2. Ensure the application contains no missing references. Launch the design IDE (use the Alt+F11 keys), and from the menu bar, select Tools, References. Remove or resolve any missing references.
3. Ensure the application compiles successfully. In the IDE view, select Debug, Compile from the menu bar. Resolve any reported errors.
4. Carry out a compact and repair on the database, using the Tools, Database Utilities, Compact and Repair Database menu option.
5. Ensure that all linked tables are valid links. Using the Tools, Database Utilities, Linked Table Manager menu option, verify that all links are up to date and pointing to an existing .mdb file that is not read-only.
If you still experience issues using the exporter tool, please supply the following information:
* Operating System
* Service Pack version
* MS Access version installed
* Version of MDB file to be exported
In your posting you mention the fact that the tool extracts the table data, generating a file with a .DAT extension for each table extracted. This is the expected behaviour of the tool. I would recommend that you read the documentation that accompanies the release, namely the Oracle Migration Workbench Exporter for Microsoft Access online help, and also the Oracle Migration Workbench User's Guide, to give you an understanding of how the tools work.
I hope this helps.
Regards,
Hilary

DB Link between Oracle 10g and Oracle 9i for CLOB data type

How do I transport XMLType or CLOB from oracle 9i to Oracle 10G using DBLink?
Is any restrction to DBLink, while transfering CLOB with XML data from oracle 9i to Oracle 10G?
Please let me know how i resolve this issue.
Thanks in advance.
DK

Well... it depends on what type of link you wish to create.
If you have same user with same password on both databases (9i and 10G), then you can create a public database link as
CREATE PUBLIC DATABASE LINK dblink USING 'dbalias';
Note: dbalias is the value from your TNSNAMES.ORA. The database from which you are creating the db link has to have the entry in TNS for other database.
Other method is to create a private db link
CREATE DATABASE LINK dblink CONNECT TO user IDENTIFIED by pwd using 'dbalias';
The number of open connections from a particular database is governed by init parameter DB_LINKS (this was in 8i.. not sure about higher versions)
