Sequences used within Oracle TExt

Are there any sequences that are used by Oracle Text which might benefit from increasing the cache_size?
Regards

Hi,
IDGEN1$ is not only used for indexing, but for more general cases in Oracle. There is bug 7694580, which is solved in 11.2. Simply stated, if the sequence cache size is 20, then you may increase the value to 1000. This is not only applicable for RAC, but for all large systems. So indeed it is allowed to increase the value (as user SYS):
alter sequence sys.IDGEN1$ cache 1000;Herald ten Dam

How to use all oracle text features under ifs?

i'd like to know that is possible to use a oracle text features like a Theme Capabilities to do a classification when documents its incoming.....

You will probably need to use dynamic SQL.
See the discussion at:
http://asktom.oracle.com/pls/ask/f?p=4950:8:::::F4950_P8_DISPLAYID:53140567326263
(while the question deals with SQLX, the answer is the same - Pro*C can't parse all SQL, but dynamic SQL is not parsed by Pro*C)

Using of Oracle Text functions not working in JDev

Hi,
I'm confused about using Oracle Text functions in JDeveloper.
It's not possible for me to pass the sql syntax test while creating a view object with a custom query:
SELECT score (1) myScore,
dokumente.titel,
ctx_doc.snippet ('idx_dokumente_titel',
TO_CHAR (dokumente.dkt_id),
'searchstring'
) snippet
FROM dokumente
WHERE contains (titel, 'searchstring', 1) > 0;
I retrieve "ORA-00911: invalid character" for the contains-function.
(Using this statement in sql-worksheet works.)
Any ideas?

Hi william,
Yes you need code abap to maintein your data. look at <a href="http://help.sap.com/saphelp_erp2005vp/helpdata/en/2f/696d360856e808e10000009b38f839/frameset.htm">Business Data Toolset</a>, in the part of Dialog.

Oracle Text query: Escaping characters and specifying progression sequences

How can I combine the escaping of a search string and the specification of progression sequences within an oracle text query
so that in all cases the correct results are delivered (see example below)?
The scenario in which to use this is the following:
+ Database: Oracle Database 10g Enterprise Edition Release 10.2.0.2.0
+ Requirement: Hitlist of results ordered by score whereby the different part within
the result list are specified using progression sequences within oracle text query
Example:
create table service_provider (
id number,
name_c varchar(100),
uri_c varchar(255)
insert into service_provider values (1,'ABB Company Mgmt','http://www.abb-company-mgmt.de');
insert into service_provider values (2,'Dr. Abbas Ming','http://www.dr-abbas-ming.de');
insert into service_provider values (3,'SABBATA United','http://www.sabbata-united.de');
insert into service_provider values (4,'ABB','http://www.abb.de');
insert into service_provider values (5,'AND Company Mgmt','http://www.and-company-mgmt.de');
insert into service_provider values (6,'Dr. Andas Ming','http://www.dr-andas-ming.de');
insert into service_provider values (7,'SANDATA United','http://www.sandata-united.de');
insert into service_provider values (8,'AND','http://www.and.de');
Query 1: works correctly in this case
select * from (
select /*+ FIRST_ROWS */ score(1), this_.*
from service_provider this_
where
CONTAINS ( this_.NAME_C , '<QUERY><textquery grammar="CONTEXT">' ||
'<progression>' ||
'<seq>abb</seq>' ||
'<seq>abb%</seq>' ||
'<seq>%abb%</seq>' ||
'<seq>fuzzy(abb,1,100,WEIGHT)</seq>' ||
'</progression></textquery></QUERY>', 1 ) > 0
order by score(1) desc, this_.NAME_C
) where rownum < 21
delivers
76     4     ABB     http://www.abb.de
76     1     ABB Company Mgmt     http://www.abb-company-mgmt.de
51     2     Dr. Abbas Ming     http://www.dr-abbas-ming.de
26     3     SABBATA United     http://www.sabbata-united.de
Query 2: procudes error
select * from (
select /*+ FIRST_ROWS */ score(1), this_.*
from service_provider this_
where
CONTAINS ( this_.NAME_C , '<QUERY><textquery grammar="CONTEXT">' ||
'<progression>' ||
'<seq>and</seq>' ||
'<seq>and%</seq>' ||
'<seq>%and%</seq>' ||
'<seq>fuzzy(and,1,100,WEIGHT)</seq>' ||
'</progression></textquery></QUERY>', 1 ) > 0
order by score(1) desc, this_.NAME_C
) where rownum < 21
produces ORA-29902, ORA-20000, DRG-50901 because AND is a reserved word in oracle text
So we need escaping ...
Query 3: does not work correctly
select * from (
select /*+ FIRST_ROWS */ score(1), this_.*
from service_provider this_
where
CONTAINS ( this_.NAME_C , '<QUERY><textquery grammar="CONTEXT">' ||

'<seq>{abb}</seq>' ||
'<seq>{abb%}</seq>' ||
'<seq>{%abb%}</seq>' ||
'<seq>fuzzy({abb},1,100,WEIGHT)</seq>' ||
'</progression></textquery></QUERY>', 1 ) > 0
order by score(1) desc, this_.NAME_C
) where rownum < 21
delivers
76     4     ABB     http://www.abb.de
76     1     ABB Company Mgmt     http://www.abb-company-mgmt.de
Query 4: does not produce an error, but also does not work correctly
select * from (
select /*+ FIRST_ROWS */ score(1), this_.*
from service_provider this_
where
CONTAINS ( this_.NAME_C , '<QUERY><textquery grammar="CONTEXT">' ||

delivers
76     8     AND     http://www.and.de
76     5     AND Company Mgmt     http://www.and-company-mgmt.de

Anywhere that you just use the word by itself, enclose it in {}, but anywhere that you add % on either side or both don't enclose it in {}. Please see the demonstration below.

Product Search Using Oracle Text or By Any Other Methods using PL/SQL

Hi All,
I have requirement for product search using the product table which has around 5 million products. I Need to show top 100 disitnct products searched in the following order
1. = ProductDescription
2. ProductDescription_%
3. %_ProductDescription_%
4. %_ProductDescription
5. ProductDescription%
6. %ProductDescription
Where '_' is space. If first two/three/or any criteria itslef gives me 100 records then i need not search for another patterns
Table Structure Is as follows
Create Table Tbl_Product_Lookup
    Barcode_number                Varchar2(9),
    Product_Description Varchar2(200),
    Product_Start_Date Date,
    Product_End_Date Date,
    Product_Price Number(12,4)
Could you please help me implementing this one ? SLA for the search result is 2 seconds
Thanks,
Varun

You could use an Oracle Text context index with a wordlist to speed up substring searches and return all rows that match any of your criteria, combined with a case statement to provide a ranking that can be ordered by within an inner query, then use rownum to limit the rows in an outer query. You could also use the first_rows(n) hint to speed up the return of limited rows. Please see the demonstration below. If you decide to use Oracle Text, you may want to ask further questions in the Oracle Text sub-forum on this forum or space or whatever they call it now.

SMB Server using Oracle Text Index

Hi folks,
I am looking into IFS and can't find any info
on whether IFS is able to use the Oracle Text
indexing, when accessed through SMB (directory mount).
If I search for a file containing a given string
is that search executed within IFS and only the
resultset returned to the client, or is every
file read from IFS delivered to the client,
searched there and then thrown away if it doesn't
contain the string (rendering the Text Index useless)?
Does anybody have background info / experience with this?
Regards
Jan-Peter

Jan-Peter To answer your question, it would help to have a little more context (pardon the pun). Are you trying to (1) understand how the 9iFS Windows UI uses Oracle Text, or (2) are you trying to write a client application that somehow uses the Text index on 9iFS content?

Document management system using oracle text

i plan to create document management system using oracle text with following features
1) document comparision
2) document search
and more...
can oracle text be used to display documents of various formats by converting them to HTML. and can search keywords be highlighted in the document.
please help!

Have you ever considered doing this in Oracle Application Express (free on top of the Oracle database)? How about something like:
http://download-west.oracle.com/docs/cd/B31036_01/doc/appdev.22/b28839/up_dn_files.htm
Index the files using the CONTEXT index, and perhaps the docs' meta with it using the Oracle Text MULTI_COLUMN_DATASTORE, and then when you write your query for a report on the documents include a search string.
I've created a number of APEX-based document management systems and it is quite easy once you get the hang of using this environment. I suggest looking at some of the tutorials/how-to documents and you'll be on your way quickly.
Start with the upload application. Once you can get your documents in, create a report that shows everything except the document. Verify all of this works correctly.
Add some "items" to the page for the report, and include them as bind variables in the where clause.
After that, add your Oracle Text index to the database, and toss in a "text-field" item to the APEX page. Modify your report query, adding the CONTAINS clause, and use the newly created item as a bind variable. There's your keyword search.
Linking to Oracle Apps is done through API's and may be over database links.
Hope it helps. Though not a step-by-step how to document, this should point you in the right direction. Get familiar with APEX as that covers most of what you described.

Extracting an oracle text indextype

oracle version 10.2.0.5
I am working on an old legacy database that has a custom indextype used by oracle text. I am not sure how to extract it. Export does not get it. I tried using
dbms_metadata.get_ddl, I get object of type indextype not found in the schema. I am using the correct object and schema name. I found it in DBA_INDEXTYPES.
I am not sure how to issue a create indextype based on what I found in dba_indextypes
I cannot use data pump due to a bug that is version/platform/upgrade specific (not looking for help on this).
I have not used oracle text often and whenever I used it, I used the built in create indextype.

What does DBA_OBJECTS say about that index?
:p

Running Oracle Text Manager w/o DBA

We've been using the Oracle Text KB and our own thesaurus to index documents on help.unc.edu for two years now. We upload the new thesaurus files with ctxload each time new terms need to be added. I have to ask my DBA to run it in the shell on the DB server. I'd really like to manage the thesaurus and KB directly using the "Oracle Text Manager" application. Can this be run without DBA privledges, by granting select privledges to some other user? Can it be run from a client instead of on the server itself?
Does anyone have recommendations in this regard?
Many thanks,

No. You can still create and distribute profiles but not through a push solution. Look at MCX in WGM or even Apple Configurator and manually distribute.
If this is a lab with no internet, how much change management do you need?

Oracle Text and Replication

We need to use an Oracle Text index on an application table in a read-only materialised-view replicated environment. The Oracle Text index needs to exist at both the master site and the materialised-view site.
We see two possible alternatives:
(1) Replicate read-only copies of the Oracle Text Index tables and indexes to the materialised view site, in addition to replication of the application table.
or
(2) Replicate only the master application table and create local instances of the Oracle Text index at both the master and materialised view sites.
Which method is best? Any experience, advice or references that you can provide would be much appreciated.
Many thanks for your help,
Peter

Oracle Text

Hi Expert,
how can i use the Oracle text to do searching with the XML documents?
as i shredded the xml documents into the SQL view already,
i cannot create index onto those views.
what can i do with the Oracle text search?
THX a lot~!
Edith

Hi Edith:
Oracle Text can index document in UTF8 or any other encoding supported by Oracle.
Assuming that your table is LRPAPER_XMLTYPE_TBL you can create a Text index with:
create index LRPAPER_XMLTYPE_TBL_idx on LRPAPER_XMLTYPE_TBL p (value(p)) indextype is ctxsys.context;If you have documents with different languages stored in the same table you has to find some scalar column to be used as discriminator value. In my example "lang" is an scalar column of type varchar2. See the annotated schema at:
http://www.dbprism.com.ar/xsd/document-v20-ann.xsd
This annotated schema creates these Oracle types:
SQL> desc "document"
Name                                      Null?    Type
SYS_XDBPD$                                         XDB.XDB$RAW_LIST_T
id                                                 VARCHAR2(4000 CHAR)
lang                                               VARCHAR2(4000 CHAR)
header                                             headerType
body                                               CLOB
footer                                             footerType
SQL> desc "headerType"
"headerType" is NOT FINAL
Name                                      Null?    Type
id                                                 VARCHAR2(4000 CHAR)
lang                                               VARCHAR2(4000 CHAR)
title                                              VARCHAR2(4000 CHAR)
subtitle                                           VARCHAR2(4000 CHAR)
version                                            versionType
type                                               VARCHAR2(4000 CHAR)
authors                                            authorsType
notice                                             VARCHAR2(4000 CHAR)
abstract                                           VARCHAR2(4000 CHAR)
meta                                               metaListSo the syntax "XMLDATA"."lang" is referencing to the attribute (column) "lang" of the type document.
Best regards, Marcelo.

Oracle Text - Compressed (ZIP) documents support

Is it possible for Oracle Text to index files of various formats like DOC, PDF, HTML compressed in the ZIP archives?
I have read some Oracle text documentation and it seems that this feature is not available out-the-box?
Does anyone have any idea how this functionality can be implemented?
I think USER_DATASTORE might be used for this, but this does not seem like a good way how to do it.
The second option is using a Oracle Text FILTER class. But the default INSO_FILTER does not support indexing of documents in ZIP packages according to my tests.
So far I was not able to find any other filters, which support this feature.
Regards.

What version of oracle are you interested in?
11.1.0.7 (the latest) returns Oracle text to INSO filters for document processing, and in [Text Reference Section B.2.5|http://download.oracle.com/docs/cd/B28359_01/text.111/b28304/afilsupt.htm#g639477] (Archive File Format), ZIP files are supported.

Oracle Text Classification/Clustering

Is anyone using the Oracle Text classification/clustering technology? I am working on a project where we are doing research on using this type of technology for our Oracle Text searches.

Thanks for your help. I will talk to the person I am working with to see if he thinks we can go this route. I know he is the one that is the contact person for the thesaurus. If I have any more questions, I'll post to this thread. It will be the first of next week before I can get with him.
Thanks,

Oracle Text Verification

I'm have an Oracle 10.2.0.2 database that was installed and configured by someone else on a RedHat machine. My background is in Geographic Information Systems, so this may seem like a very simple question.
I need to run a service that relies on Oracle Text. Is there any way to verify that Oracle Text is installed and running? The docs say that Text is installed by default, but I can't tell if it's running. I don't see a schema named CTXSYS.
The second question, I guess, is if Oracle Text is installed, how can I get it running?
Any help would be appreciated.
-Brendan

Oracle Text should be there by default. If the CTXSYS user does not exist, then either the database has been repeatedly upgraded from an early version where it was not a default, or someone has deliberately removed it. I'm not sure how you would go about reinstalling the CTXSYS user and schema, though it's certainly possible to do. I'd strongly suggest getting Oracle Support to talk you through the process.
Nothing needs to started, as such.
To check whether Oracle Text is installed and working, try this simple test:
create table x (y varchar2(2000));
insert into x values ('the quick brown fox');
create index xi on x(y) indextype is ctxsys.context;
select * from x where contains (y, 'fox') > 0;
For more advanced use of Oracle Text your user will need the CTXAPP role.
