Oracle Text Wizards (CatSearch)

Will the Oracle Text wizards (CatSearch and Text search) be made available for JDeveloper 10g? When? If not, what did they do and how could I recreate manually? Thanks.

Is there any ETA.
I have to work out a POC for a customer and the only have 905 JDeveloper. When will this extension be available.

Thank you

I believe that extension was built for JDeveloper 9.0.4. The extension API changed slightly after 9.0.4, so it may not work in 9.0.5.1.
You might want to check on the database forums to see if they have any plans to update this extension.

Oracle Text performance -- failed attempts

We are trying to implement a simple search of text data stored in a heavily used table (inserts/updates). There are 3 columns to index --
Headline (varchar2(255))
Subheadline (varchar2(255))
Teaser (varchar2(4000))
The first attempt to implement Oracle text w/ CATSEARCH
begin
ctx_ddl.create_index_set('cms_iset');
ctx_ddl.add_index('cms_iset','poolid_cp, mediaid_cp'); /* sub-index A */
end;
---- We knew we were going to filter on poolid_cp and mediaid_cp ---
CREATE INDEX cms_headlineidx ON con_properties (headline)
INDEXTYPE IS ctxsys.CTXCAT
PARAMETERS ('index set cms_iset');
CREATE INDEX cms_subheadlineidx ON con_properties (subheadline)
INDEXTYPE IS ctxsys.CTXCAT
PARAMETERS ('index set cms_iset');
CREATE INDEX cms_teaseridx ON con_properties (teaser)
INDEXTYPE IS ctxsys.CTXCAT
PARAMETERS ('index set cms_iset');
*********THE RESULTS*************
Our application server would spin up threads that would appear to be hanging. The load on the DB servers (RAC) were higher than normal. This implementation would have saved on having to do resync's manually.
The next attempt was implementing w/ CONTEXT:
alter table con_properties add (dummy varchar2(1));
begin
ctx_ddl.create_preference('con_propsearch', 'MULTI_COLUMN_DATASTORE');
ctx_ddl.set_attribute('con_propsearch', 'columns', 'headline,subheadline,teaser');
end;
CREATE INDEX con_properties_searchidx
ON con_properties(dummy)
INDEXTYPE IS CTXSYS.CONTEXT
PARAMETERS ('datastore CTXSYS.con_propsearch')
Records getting put into the ctx_user_pending table a few hundred per hour.
********THE RESULTS*************
Same issue with the application servers spinning off threads that seem to be hung. Spikey load on the DB servers (RAC).
NOTE: In both implementations, running search querys ran OK. However, dropping the text index in BOTH cases caused the application servers to behave normally.
Can anyone tell me what's going on internally with Oracle TEXT when a table is heavily inserted and updated? What is going on in the background. Is there some sort of lock that the app servers are waiting on? I know there is "overhead" with inserts on a normal b-tree index. Is it "exponential" with Oracle Text?
Thank you!

When documents in the base table are inserted, updated, or deleted, their ROWIDs are held in a DML queue until you synchronize the index. You can view this queue with the CTX_USER_PENDING view. Apparently, you are not synchronizing your context index, so the queue is building infinitely. You need to establish some method of synchronizing your index. You can use parameters('sync(on commit)') in your index creation or create an after insert or update statement level trigger, not row trigger, that uses dbms_job.submit to schedule ctx_ddl.sync_index to synchronize the index upon commit of the dml or you can manually run ctx_ddl.sync_index periodically or schedule it or you can alter and rebuild your index periodically or you can drop and recreate it periodically. Which method you choose depends on how current the information that you query needs to be. If your data needs to be current up to the moment, the you should sync on commit. Otherwise it may be better to do it in periodic batches.

Oracle text catsearch sub index query

Hello,
I wonder if you can help me with a query about Oracle Text Catsearch.
I have a database which has 10Gb of data.
There is a text column in the database on which I have to find a partial match on the data contained in it
I have indexed this column with a CTXSYS.CTXCAT index.
In addition I have added a sub index to the index set for a Date Field and ran EXEC DBMS_STATS.GATHER_TABLE_STATS to make sure the query execution path is optimised
Here's my Question:
How can I make sure that the Date sub query always runs before the finding the Partial Match on the text column?
Caveat I am a programmer not a DBA, but I've ended up doing some databasey type stuff, apologies if question is thick.
Cheers
Mark
p.s. Performance is good, but I have a feeling that the Date subquery is not being used as efficiently as it should be (the subquery should massively reduce the result set to be searched for the partial match)

You can't - ctxcat doesn't support the "functional invocation" which would be needed if another index is used first. So reducing the set of docs to index doesn't help.
If you can find a way to denormalize the information used in the sub-query such that it can be included in the main query index set, that should help performance considerably.

Searching using Oracle Text instead of LIKE '%'

Hello all,
I hope you help me in this:
I have a table looks like this
create table subscribers (
id numer(10),
first_name varchar2(30),
father_name varchar2(30),
grandfather_name varchar2(30),
last_name varchar2(30))
The application is built using Oracle Forms. Many times, the end users are not so sure of the spelling of the name, therefore they use the "%" wildcard with name fields. This will be reflected to the queries the application will send them to the Oracle Server.
We have the following queries
1) select *
from subscribers
where last_name like '%family_name%';
2) select *
from subscribers
where last_name like 'family_name%';
3) select *
from subscribers
where last_name like '%family_name%' and first_name like '%first_name%';
4) select *
from subscribers
where last_name like 'family_name%' and first_name like 'first_name%';
As well as searching on the father_name and grandfather_name fields. But most of the search are on the first_name and the last_name.
These queries are killing the server since we have millions of records. BTree indexes will not help here because of the LIKE and the "%"
I am thinking to use Oracle Text here, but I am not sure whether I have to go for a CONTEXT index on each individual column, or I can use the MULTI_COLUMN_DATASTORE indexing.
Any idea will be appreciated

The ctxcat index and catsearch operator are generally intended for usage with one text column and one or more columns of structured data. You would have to pick just one of your columns as the text column and the others as structured columns. I would be more inclined to use the multi_column_datastore with a context index and contains operator, so that you can search all of your columns as text columns.

Oracle Text and webDAV

Hello, I am using Portal 9.0.2.6.
I have many html items which were added through the webDAV interface. My Oracle Text search doesn't seem to pick them up. The Oracle Text search is picking up items which were added through the Portal wizard interface, so I believe Text is working.
Should it be working with the webDAV objects too?
Thanks.

Are these same HTML files searchable when you uploaded them as Portal file items through the browser?
Look at the ctx_user_index_errors view in the Portal repository schema. Are there indexing errors for the HTML files? It sounds like you are familiar with Oracle Text but if not take a look at the Portal Configuration Guide. If you don't have this to hand you can find it on Portal Center. There's a section on Search which includes all of the behind the scenes configuration of Oracle Text with Portal.

ORACLE TEXT INDEX ON VARCHAR2 COLUMN

Hello All,
I find a search in our application very slow so i thought of using ORACLE TEXT CTXCAT index based search but i find certain inconsistencies . How can this be avoided....The following query should not return result if i can replace with oracle text but i find few values....why is that...i have also given few sample results below....
SELECT first_name

The script used for creating index is
begin
ctx_ddl.create_preference('mylex', 'BASIC_LEXER');
ctx_ddl.set_attribute ( 'mylex', 'index_themes', 'NO');

Where am i wrong i could not guess a trend in the results other than all being in lower case.....

Catsearch does not support leading wildcards. As a workaround, you can use a query template with context grammar. Please see the reproduction and solution below.

using oracle 10gr2 on windows server 2003
i have tried 1)dropping the index and creating it again, the index type is "CTXSYS"."CTXCAT"
2) deleting the stats -checking
3)recreating the stats- checking
the table here is a materialized view
i need to tell you people that
there are two indexes cat_types_ind and cat_ids_idx on cat_types and cat_ids columns respectively
the inner query uses cat_types_idx index when executed and seen in sqladvisor
1)removing the order by clause will make the query work but i really want that order by clause
2)the inner-query-only works fine
3) i have seen the forums and they have helped regarding the things i tried above but it does not work
please tell me if i need to further elaborate on anything
thanks in advance

Oracle Text:Problems in starting

hi all
i am working on Oracle 10g in windows and i want to do Text Mining,but i am having some problems.when i use the JDeveloper and start the text wizard it createa a jsp file but it is not loading properly.is there any document from which i can learn how to do it.i think i missed out some configurations for the http server.i really need it very soon.
thanks in advance

hello
i had followed the tutorial "Building JSP Applications that Use Oracle Text to Search Content in the Database using JDeveloper" and using that now i am able to load the jsp file but cant search as it shows the following error.
The requested method POST is not allowed for the URL /textsearch/mysearch.jsp.
i dont know what is the problem.can u help me.i am using Oracle 10g and i have added a Alias in the httpd.conf instead of the ojsp.conf file that has been mentioned in the tutorial as there is no such file in 10g.can u help me

Oracle text indexes

Can anybody know is it possible to create two oracle text indexes on one column, for example, CTXCAT index and CTXRULE index and what will be during the querying of that column? is it a good practise?
Thanks in advance.

When in doubt, test and see. Yes, you can create two different types of Oracle Text indexes on the same column. If you create a CTXCAT index and a CTXRULE index, then queries using CATSEARCH will use the CTXCAT index and queries using MATCHES will use the CTXRULE index. When querying with CATSEARCH, it will find all rows where the terms searched for are found within the column value. When querying with CTXRULE, it does the opposite, and finds all rows where the column values are found within the terms searched for. Please see the demonstration below. As to whether it is a good practice, it depends on what you need. If you need both types of searches, then yes. If not, then no, it would be unnecessary overhead.

Process for Oracle Text

am working as a dba and we plan to introduce oracle text for text search. since I am new to this concept, I would like to know step by step implementation of Oracle text. I've searched some web sites but still not clear on the implementation part.
Please help me out

Hi,
Oracle Text is included in both standard and enterprise editions of the data server. When you are creating your database, select Oracle Text during configuration (one of the options). You will then have Oracle Text available on your database. The schema name is CTXSYS. You need to unlock this account just like any other.
To use Text, either grant permissions on the specific objects you need for the user, or use the CTXAPP role. It is up to you to know the permissions required for the objects (in other words, I can't tell you your requirements), so research this in the reference manual.
At this point, it is ready to use. Just create your indexes according to the Oracle Text Developer's Guide (you can find this with all of the documentation - look at the Application Developer's tab in Doc Library). Your search syntax depends totally on your requirements, and the type of index you choose to create. For example, the CONTEXT index uses the CONTAINS operator, and the CTXCAT index uses CATSEARCH (unless of course you want to use templates, but let's not go there just yet...).
There are two references you will want to review: The Oracle Text Developer's Guide and the Oracle Text Reference.
Hope this helps,
Ron

I just noticed that I forgot to use an empty stoplist, so I have added that to the revised example below. Otherwise, it uses a default stoplist that would not index common single-letter words like A and I.
1. Whtat is Just search on single character 'L'? It give me error.
Since it uses the NEAR operator, searching for just one letter causes incomplete syntax, asking it to search for L near a missing second value. So, I have added additional code to allow for just one letter.
2. How do I do auto refresh on this index on datastore?
If I add "sync        (on commit)" it does not refresh the previously set token.
Sync(on commit) does synchronize so that the data is immediately searchable. You have to either optimize or rebuild or drop and recreate the index to condense the rows in the domain index table.
3.lastly explanation of
<seq>NEAR((' || letters_func (:search_string) || '),1,TRUE)</seq>
                  <seq>NEAR((' || letters_func (:search_string) || '),100,TRUE)</seq>
                <seq>NEAR((' || letters_func (:search_string) || '),100,FALSE)</seq>
why 100 true and 100 false
100 is just a default value that I used for the second parameter of near, indicating how close the letters need to be to each other. True and False are values for the third parameter of near, indicating whether or not the letters must be in the same order or not. So, it returns the results in the order of first those that are very close to one another and in the same order, then those that may be further away but in the same order, then those that may be further away and in any order.

Announcement - New JDeveloper Text wizards

The Text and Catalog Search Wizards are add-ins for JDeveloper9i which provide a menu-driven interface for generating simple Text and Catalog Search applications.
The source code is generated through JDeveloper and can be easily modified.
You can download the wizards from the Text page (otn.oracle.com/products/text -> software).
There is an OBE lesson that shows how to use them: http://otn.oracle.com/products/oracle9i/htdocs/9iober2/obe9ir2/obe-cnt/html/jdevtext/jdevtext.htm

Hi,
has anyone tried to use the Text Wizard using the OC4J Server in JDeveloper9i (v 9.0.3)?
I've followed the OBE lesson instructions to the letter (many times!) but omitting the Apache alias setup.
I get Error 404 every time.
Any suggestions?
Brian
