Oracle Text (schema CTXSYS): additional licence costs?
Hi,
it's my understanding that through installing and using Oracle-Text (schema CTXSYS) no additional licence costs arise (for Oracle Enterprise Edition).
I'm asking this question in this forum just to be sure that my understanding is not wrong...
Many thanks
JH
As far as I know this is correct.
Oracle Text is neither listed as an Entreprise Edition option in US price list:
http://www.oracle.com/us/corporate/pricing/technology-price-list-070617.pdf
nor in Licensing Information:
http://download.oracle.com/docs/cd/E11882_01/license.112/e10594/toc.htm .

Oracle Text in installing Oracle 10g without licence!!
Hi. Everyone.
I've read some thread , but I am still confused about "oracle text".
Now, I am testing oracle10g database.
I downloaded 10g software from www.oracle.com, and installed it sucessfully
on windows xp.
When I was trying to import a dump file from oracle9i to
the unlicenced oracle10g database, I got the error , IMP-00017, which
is related to "Oracle Text".
I checked "dba_users" dictionary, but ctxsys user is locked and expired.
I read some thread on this site, and according to the advice, I tried to
enable oracle text, using "DBCA".
However, every database option on DBCA is disabled, I was not able to
check oracle text.
Lastly, how can I enable "Oracle Text" with unlicenced oracle 10g ?
Is this possible without licence?
I am very confused about this.
I am looking forward to hear your experience and advices.
Have a nice day.
Best Regards.
Ho.Well, instead of being confused, you could go to http://www.oracle.com/pls/db102/portal.portal_db?selected=1 and look at
1) the licensing document, which would tell you whether you need a separate license, and
2) under the 'Books' tab, look at the Text Application Developer's Guide or the Text Reference manuals for details.
You could also look for the Oracle Text forum (from the http://forums.oracle.com page, under Database - More, or Text and ask the people who concentrate on that set of features.
In general, Oracle Text is a set of extensions, the definitions for which are stored under user ctxsys. You would use these extensions by creating your own objects that are based on the extensions.
For example, suppose your tables contain varchar2 columns. Create indexes that are based on ctxsys's 'context index type' and your application can then use the 'CONTAINS' keyword search capability (which is effectively a ctxsys-owned extension to the select)
However, you would never log on to ctxsys and do anythibng with that as you risk changing the template code that Oracle has supplied.

Oracle Text Index Error - DRG-10700: preference does not exist: CTXSYS.DEFA
Hi we are having a Oracle 11g db.And we have installed CTX SYS package and provided the grants to the required schema.
But while creating the oracle text index, following error is thrown:
ORA-29855: error occurred in the execution of ODCIINDEXCREATE routine
ORA-20000: Oracle Text error:
DRG-10700: preference does not exist: CTXSYS.DEFAULT_LEXER
ORA-06512: at "CTXSYS.DRUE", line 160
ORA-06512: at "CTXSYS.TEXTINDEXMETHODS", line 365
Following grnats are given :
GRANT EXECUTE ON CTXSYS.CTX_DDL TO <schema_name>;
GRANT APPOWN TO <schema_name>;
GRANT CTXAPP TO <schema_name>;
I have verifyed the ctxsys.CTX_PREFERENCES view which is having an entry as :
SELECT PRE_OWNER, PRE_NAME
FROM CTXSYS.CTX_PREFERENCES
WHERE PRE_NAME = 'DEFAULT_LEXER';
The Result is :
PRE_OWNER PRE_NAME
SYS DEFAULT_LEXER
Can you please assist if there is a way to update the permission on this DEFAULT_LEXER preference to set the PRE_OWNER as CTXSYS ?
ThanksThat's odd. If I run the same query I see:
SQL> SELECT PRE_OWNER, PRE_NAME
2 FROM CTXSYS.CTX_PREFERENCES
3 WHERE PRE_NAME = 'DEFAULT_LEXER';
PRE_OWNER PRE_NAME
CTXSYS DEFAULT_LEXERAre all your defaults like thsi? What do you see if you run
select pre_owner, pre_name from ctxsys.ctx_preferences where pre_name like 'DEFAULT%';
It would be easy enough to update the underlying table DR$PREFERENCES to fix the owner, but who knows what else might be wrong.
Has this database been updated from a 9i installation by any chance? -

Are there any licencing costs for Oracle Clients ?
11.2/Solaris 10
In my shop, we only install Oracle Client of type Instaclient (not the 'Administrator' type). Instaclient is very basic ; it only has some basic library files and sqlplus binary (no tnsping , exp, imp,...etc). I think they are doing this for saving licence costs.
Does oracle actually charge for Oracle Client installations ? If so, is there a significant cost difference between 'Administrator' type and 'Instaclient' type ?Max wrote:

Oracle Text, ctxsys.context problem with number column

Is there any solution to create ctxsys.context index on number column ? Or I have to create other index type ?
When I try do that (create ctxsys.context index), I get
09:01:18 ORA-29855: wystąpił błąd przy wykonywaniu podprogramu ODCIINDEXCREATE (An error has occurred in the performance of the subprogram)

09:01:18 ORA-06512: przy "CTXSYS.TEXTINDEXMETHODS", linia 366Btw, is there possible to search like "*LIKE %123%*" clause any of index (in contains) ?
Edited by: Ndejo on 2012-11-21 00:53The multi_column_datastore says that the text to be indexed should be fetched from the supplied COLUMNS list rather than from the actual column the index is created on.
So in this case we're fetching the contents of "theNumber" column, converting it to text, and indexing it.
You don't necessarily need a dummy column, if "a_title" is a varchar column you could create the index on that instead.
For example:
SQL> create table mytab( a_id number, a_code number, a_title varchar2(80), a_subtitle varchar2(80), a_info clob );
Table created.
SQL> insert into mytab values ( 12, 9812376, 'foo is the title',
2 'foobar is the subtitle', 'the info column will not be indexed' );
1 row created.
SQL> exec ctx_ddl.drop_preference( 'myds' )
PL/SQL procedure successfully completed.
SQL> exec ctx_ddl.create_preference( 'myds', 'MULTI_COLUMN_DATASTORE' )
PL/SQL procedure successfully completed.
SQL> exec ctx_ddl.set_attribute( 'myds', 'COLUMNS', 'a_code, a_title, a_subtitle' )
PL/SQL procedure successfully completed.
SQL> create index myindex on mytab (a_title) indextype is ctxsys.context
2 parameters ('datastore myds');
Index created.
SQL> select a_id from mytab where contains (a_title, '%123%') > 0;
A_ID
12
SQL> select a_id from mytab where contains (a_title, 'foo') > 0;
A_ID
12If you want to be able to search within a particular column, then add "section group CTXSYS.AUTO_SECTION_GROUP" to the parameters clause, and you can then do:
SQL> select a_id from mytab where contains (a_title, 'foobar WITHIN a_subtitle') > 0;
A_ID

Hi
We are creating a oracle text index on one table . The table contains 200 million records
The script is failing in the middle by giving the error unable to extend temp segement by 128 in temp table space.
Can you please provide any suggestions of how this issue can be rectified.
Also Can we use nosort option with text indexes.
Regards
RamakrishnaAre you using automatic PGA work area sizing?
You could switch to manual for this session and override sort_area_size.
Also, memory parameters of index can be changed.

Installation of Oracle Text in Oracle 10g
Hi All,
Could you please help me in installing ORACLE TEXT in Oracle 10g. What exactly ils this feature and how I can install it.
Regards
Harpreet SinghYou don't need the companion CD to install Oracle Text.
Oracle Text is installed by default if you have created your database using DBCA.
However, if your database has been installed manually you may need to install this feature additionally.
In order to check if the feature is already present check if CTXSYS schema exists:
SQL> select username
2 from dba_users
3 where username='CTXSYS';
USERNAME
CTXSYS
SQL>Cheers,
Mihajlo -
HI,
I have a application which runs on mod_plsql procedural concept using WebDB as DAD.
I have some schema's like "CTXSYS" AND "MDSYS" as part of the database.
My Question, is it OK, if delete these schema's ?
Thanks in advance.MDSYS provides the objects needed to run Oracle Spatial and Oracle Locator. CTXSYS provides the objects needed to run Oracle Text.
Oracle Text and Oracle Locator are free with the database.
Instead of deleting them, why not find out how you can cut the cost of your developer's code by using them effectively?
If you really want to delete them, use the installer to remove the capabilities. Do NOT drop the schemas manually. -
Error while running the Oracle Text optimize index procedure (even as a dba user too)
Hi Experts,
I am on Oracle on 11.2.0.2 on Linux. I have implemented Oracle Text. My Oracle Text indexes are fragmented but I am getting an error while running the optimize_index error. Following is the error:
begin
ctx_ddl.optimize_index(idx_name=>'ACCESS_T1',optlevel=>'FULL');
end;
ERROR at line 1:
ORA-20000: Oracle Text error:
ORA-06512: at "CTXSYS.DRUE", line 160
ORA-06512: at "CTXSYS.CTX_DDL", line 941
ORA-06512: at line 1
Now I tried then to run this as DBA user too and it failed the same way!
begin
ctx_ddl.optimize_index(idx_name=>'BVSCH1.ACCESS_T1',optlevel=>'FULL');
end;
ERROR at line 1:

ORA-06512: at "CTXSYS.CTX_DDL", line 941
ORA-06512: at line 1
Now CTXAPP role is granted to my schema and still I am getting this error. I will be thankful for the suggestions.
Also one other important observation: We have this issue ONLY in one database and in the other two databases, I don't see any problem at all.
I am unable to figure out what the issue is with this one database!
Thanks,
OrauserNHow about check the following?

Is Oracle Text the right solution for this need of a specific search!
Hi ,
We are on Oracle 11.2.0.2 on Solaris 10. We have the need to be able to do search on data that are having diacritical marks and we should be able to do the serach ignoring this diacritical marks. That is the requirement. Now I got to hear that Oracle Text has a preference called BASIC_LEXER which can bypass the diacritical marks and so solely due to this feature I implemented Oracle Text and just for this diacritical search and no other need.
I mean I set up preference like this:
ctxsys.ctx_ddl.create_preference ('cust_lexer', 'BASIC_LEXER');
ctxsys.ctx_ddl.set_attribute ('cust_lexer', 'base_letter', 'YES'); -- removes diacritics
With this I set up like this:
CREATE TABLE TEXT_TEST
NAME VARCHAR2(255 BYTE)
--created Oracle Text index
CREATE INDEX TEXT_TEST_IDX1 ON TEXT_TEST
(NAME)
INDEXTYPE IS CTXSYS.CONTEXT
PARAMETERS('LEXER cust_lexer WORDLIST cust_wl SYNC (ON COMMIT)');

PAUL HERNANDEZMy entire need was only to be able to do a search that bypasses diacritical characters. To implement Oracle Text for that reason, I am wondering if that was the right choice! More so when I am now finding that the functionality of LIKE is not available in Oracle Text - the Oracle text search are based on tokens or words and they are different from output of the LIKE operator. So may be should I have just used a simple function like below and used that for my purpose instead of using Oracle Text:
This function (remove_dia) just removes the diacritical characters and may be for my need this is all that is needed. Can someone help to review that given my need I am better of not using Oracle Text? I need to continue using the functionality of Like operator and also need to bypass diacritical characters so the simple function that I have meets my need whereas Oracle Text causes a change in behaviour of search queries.
Thanks,
OrauserNIf all you need is LIKE functionality and you do not need any of the complex search capabilities of Oracle Text, then I would not use Oracle Text. I would create a function-based index on your name column that uses your function that removes the diacritical marks, so that your searches will be faster. Please see the demonstration below.

Thanks,
VarunYou 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.

Hi Masters,
I am working on Oracle Text. I have executed the below step/commands. All are executed successfully. But I didn't seen any improvement in my task. But I have one doubt, will explain below.
create table ent_dnt as select * from entitlement_dnt;
BEGIN
CTX_DDL.CREATE_PREFERENCE ('oracletext_datastore', 'MULTI_COLUMN_DATASTORE');
CTX_DDL.SET_ATTRIBUTE
('oracletext_datastore', 'COLUMNS',
'ORDER_NUMBER, GENERIC_PRODUCT_NAME_EXT, ENTITLEMENT_REF_ID, DEVICE_ASSET_ID, DEVICE_UNIQUE_ID, SWSERVICETAG, PRODUCT_DESC');
END;
CREATE INDEX idx_oracle_text
ON Ent_dnt (search_cols)
INDEXTYPE IS CTXSYS.CONTEXT
PARAMETERS ('DATASTORE oracletext_datastore');
BEGIN
DBMS_STATS.GATHER_TABLE_STATS('EE', 'ent_DNT', cascade=>TRUE);
DBMS_STATS.GATHER_TABLE_STATS('EE', 'upd_DNT', cascade=>TRUE);
dbms_stats.gather_index_stats('EE', 'idx_oracle_text1');
dbms_stats.gather_index_stats('EE', 'idx_oracle_text');
END;
the above steps are created / executed successfully. But when execute my select query..I didn't seen anywhere oracle text index name in my explain plan.
