Recreating indexes of type: ctxsys.context
For a database on Oracle 10g, I need to output a script that recreates all indexes of type of ctxsys.context type. I can do it running this query:
SELECT owner, index_name, DBMS_METADATA.get_ddl('INDEX', index_name, owner)
FROM all_indexes
WHERE ityp_owner = 'CTXSYS' AND ityp_name = 'CONTEXT';However, if an index has parameters like this:
CREATE INDEX <MySchema>.<Index_name> ON <MySchema>.<Index_name>
(BL_RESOLUCION)
INDEXTYPE IS CTXSYS.CONTEXT
PARAMETERS('sync (every "FREQ=DAILY; BYHOUR=1")')
NOPARALLEL;If I run DBMS_METADATA.get_ddl function, I get this output script:
CREATE INDEX <MySchema>.<Index_name> ON <MySchema>.<Index_name>
(BL_RESOLUCION)
INDEXTYPE IS CTXSYS.CONTEXT;How to include the parameter line?

When you post always provide your 4 digit Oracle version (result of SELECT * FROM V$VERSION); 10g is not a version.
Works for me on Oracle Database 10g Enterprise Edition Release 10.2.0.1.0 - Prod
CREATE INDEX "SCOTT"."NDX_TEST_CONTEXT" ON "SCOTT"."DEPT" ("DNAME")
INDEXTYPE IS "CTXSYS"."CONTEXT" PARAMETERS ('sync (every "FREQ=DAILY; BYHOUR=1")')Post information about which user is running that query and which user owns the index that is giving the problem.
Have you tried the query using a DBA user?

Question: create index indextype is ctxsys.context whith NOLOGGING
Dear All,
I would like to ask a question about
CREATE INDEX <index_name> ON <table_name> ( <index_col> ) INDEXTYPE IS CTXSYS.CONTEXT PARAMETERS ( ... )maybe you experienced that ctxsys.context index creation takes long time.
When you create a ctxsys.context index it is obvious to reduce the workload of the RDBMS. In this case I would like to reduce the I/O load with NOLOGGING option.
Firstly, I try to put the index into a tablespace with no logging option. I don't know why but it is not working. Watching the alert.log file I diagnose that redo log generated simultaneously while index generated (there are no other activity on RDBMS).
Q1 (optional): Why generating redo on object of NOLOGGING tablaspace ?
I think there are better solution: use the NOLOGGIN option of the create index command which is very simple to use at column indexes.
Which unclear to me how should I use in CREATE INDEX .. INDEXTYPE IS CTXSYS.CONTEXT command.
Fllowing the CREATE INDEX command syntax seems oubvious - but it provides sytax error.
Maybe this is why CREATE INDEX .. INDEXTYPE IS CTXSYS.CONTEXT needs something different for options: PL/SQL
example captured (for options):
begin
ctx_ddl.create_preference ('mystore', 'BASIC_STORAGE');
ctx_ddl.set_attribute ('mystore', 'I_INDEX_CLAUSE', 'tablespace users storage (initial 32k) compress 2');
end;
CREATE INDEX docs_idx ON my_docs(doc) INDEXTYPE IS CTXSYS.CONTEXT PARAMETERS ('STORAGE mystore');Q: How can I specify NOLOGGING option? In the index command? In the attribute? What is the exact syntax if NOLOGGING is allowed at ctxsys.context?
Oracle version: 11.1.0.6.0
Any advice, highly appreciated.
IstvanYou have to specify nologging in storage preference.
See Avoiding Redo Logging for an Oracle Text Domain Index (Doc ID 432762.1)
Example:
begin
ctx_ddl.drop_preference('my_storage');
end;
begin
ctx_ddl.create_preference('my_storage','BASIC_STORAGE');
end;
begin
ctx_ddl.set_attribute('my_storage', 'i_table_clause','tablespace foo1 storage (initial 5M next 10M pctincrease 0 freelists 24 freelist groups 24) nologging');
ctx_ddl.set_attribute('my_storage', 'k_table_clause','tablespace foo2 storage (initial 5M next 10M pctincrease 0) nologging');
ctx_ddl.set_attribute('my_storage', 'r_table_clause','tablespace foo3 storage (initial 5M next 10M pctincrease 0) lob(DATA) store as (nocache nologging) nologging');
ctx_ddl.set_attribute('my_storage', 'n_table_clause','tablespace foo4 storage (initial 5M next 10M pctincrease 0) nologging');
ctx_ddl.set_attribute('my_storage', 'p_table_clause','tablespace foo5 storage (initial 5M next 10M pctincrease 0) nologging');
ctx_ddl.set_attribute('my_storage', 'i_index_clause','tablespace foo6 storage (initial 5M next 10M pctincrease 0) compress 2 nologging');

Ctxsys.context index on registered schema xmltype column
9iR2
Is it possible to create a text index (indextype is ctxsys.context) on a schema registered xmltype column?
I tried it, the index creation works fine.
After the first insert statement the Oracle process seems to hang. (CPU 100%, increasing memory consumption)Yes, I previously entered some data.
Test case:
1. register schema
begin
DBMS_XMLSCHEMA.REGISTERSCHEMA('http://localhost/JobPositionSeeker-1_1.xsd',
getDocument('JobPositionSeeker-1_1.xsd'), TRUE, TRUE, FALSE, FALSE
end;
2. create table
CREATE TABLE application_xml of XMLType
XMLSCHEMA "http://localhost/JobPositionSeeker-1_1.xsd" ELEMENT "JobPositionSeeker"
3. entered some data
4. created the index
create index applicant on application_xml ( SYS_NC_ROWINFO$)
indextype is ctxsys.context
5. select using index
select value(a).getClobVal() from application_xml a
where contains( value(a),'%ai% INPATH(//PersonalData/PersonName/FamilyName)')>0
6. insert another record
-> crash -
Creating CTXSYS.CONTEXT type index for orddoc
Hi,
We tried to create a index for a orddoc datatype , the syntax used was as below
CREATE INDEX CIX_DLX_ASSET1 ON DLX_ASSET(TEXT_ASSET.source.localdata) INDEXTYPE IS CTXSYS.CONTEXT;
where DLX_ASSET is the table name and TEXT_ASSET is of the type Orddoc.
When we tried to create the index we are getting the below error message

But the index is being created but it is not proper and contain query doesnot work properly on it
However we were able to create an index for TEXT_ASSET.comments as below
CREATE INDEX CIX_TBL_ASSET1 ON TBL_ASSET(TEXT_ASSET.comments) INDEXTYPE IS CTXSYS.CONTEXT;
The step we had followed are as below

Hello everybody,
I have from time to time to create Intermedia or Oracle text indexes in Oracle databes, most 10g ones.

6) connect sa/*****;
7) CREATE INDEX pj_index ON sa.tpiecejointe(pjcontenu) INDEXTYPE IS ctxsys.context parameters ('sync (every "SYSDATE+12/24")');
My issue occured at the 7th step:

for using the sync parameter, the user needs to be granted to execute a job. Oracle makes a job to do the sync. So issue:

Indexing pdf documents with indextype ctxsys.context
I have an application that stores the contents of uploaded documents in BLOB data fields. We provide web pages which search through the uploaded documents based on text entered by the user. We currently upload both MS Word .doc and HTML documents. For the HTML documents, which are made available to the public, we index the table with the following procedure:
CREATE OR REPLACE procedure WEBADMIN.index_redacted_docs is
begin
declare
cur PLS_INTEGER;
exec_int PLS_INTEGER;
counter number;
begin
select count(*) into counter
from user_indexes
where index_name = 'DOCS_CTX_REDACTED_IDX';
if (counter = 1) then
ctx_ddl.sync_index (idx_name => 'docs_ctx_redacted_idx');
else
cur := DBMS_SQL.OPEN_CURSOR;
DBMS_SQL.PARSE (cur, 'create index docs_ctx_redacted_idx on documents_ctx_redacted (blob_content) ' ||
'indextype is ctxsys.context parameters (''filter ctxsys.null_filter'')', DBMS_SQL.NATIVE);
exec_int := DBMS_SQL.EXECUTE (cur);
DBMS_SQL.CLOSE_CURSOR (cur);
end if;
exception
when others then
DBMS_SQL.CLOSE_CURSOR (cur);
raise;
end;
end;
We run this process after every uploaded HTML file and are able to locate documents which contain any text entered by the user. The portion of the command we use to query the documents_ctx_redacted table (blob_content is the BLOB field in this table) is (using "corn" as a sample query text):
WHERE (contains (BLOB_CONTENT, 'corn', 10) > 0)
Our customer is now asking that PDF files be uploaded as well and searched in the same manner. After the PDF files are uploaded (into the same table as the HTML files) and the index updated, with the above command ctx_ddl.sync_index (idx_name => 'docs_ctx_redacted_idx'), since the index already exists, we cannot get any rows returned with the above WHERE (contains .... ) clause. We know the text we're looking for (such as "corn") is contained in the PDF files, but the search does not find them, although it finds the HTML documents just fine. I've also tried dropping the index entirely and recreating it, but that also only finds the HTML documents but not the PDF's.
What are we doing incorrectly with the PDF files? Thanks.We are using Oracle version 10.2 . I looked at the relevant Oracle Text documentation for that version, and the best I could glean was that PDF files are supported by the filter ctxsys.auto_filter (rather than null_filter) when creating the index. I dropped the existing null_filter index and created a new index with the auto_filter parameter, but the end result was the same. I still get no PDF records found when issuing the command (using "corn" as the text query)
WHERE (contains (BLOB_CONTENT, 'corn', 10) > 0)
although the HTML records show up fine again. -

hi all,
i've a problem with index with ctxsys.context index
i created it on a table has a field (description of a certain component)
the field's type is VARCHAR2(256)
The query performed is
select count(*) from Loaded_Table_Test
where contains(F8,'%Resistor%') > 0;
it returns many records
THE PROBLEM IS
after many days of perfoming the same query it seems like its
not working :the query returns nothing
I wounder if anybody can help me,Thanks in advance
Rasha FayezDoes it return an error message? If you're doing this in a application,
try it in SQL*Plus to see.
Most likely reason for this is that you're getting "query too complex".
This could start happening, even though the query used to work, if more records
have been added to the table and therefore increased the number of
expansions for '%resistor%'.
Double truncation like this is not generally a good idea. Even if you don't
get the 'query too complex error', the query will perform poorly unless you
have the SUBSTRING_INDEX option in use.

Oracle Text, ctxsys.context problem with number column

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

DRG-50857 and ORA-12838 error while INDEXTYPE IS CTXSYS.CONTEXT
Hi Experts,
I've been encountering an issue while creating INDEX.
If I execute the below script from SQLDEVELOPER line by line, then the index gets created but the weirdest thing is, if I executed the same as one sql file from SQLPLUS or SQLDEVELOPER, I get the error shared below. As we need to deliver as one sql file to customer, how can we fix this issue?
Below is the content of my sql file
ALTER SESSION ENABLE PARALLEL DML;
ALTER SESSION FORCE PARALLEL QUERY;
CREATE INDEX APPS.TEST_N1 ON APPS.EMP_TABLE
EMP_NAME
INDEXTYPE IS CTXSYS.CONTEXT PARALLEL 32;
ALTER INDEX APPS.TEST_N1 NOPARALLEL;
COMMIT;
Below is the error
Session altered.

Commit complete.I get the same error in 11g, as shown below, but not in 12c, as shown below that. So, it looks like there has been a change in the way that Oracle Text does things between versions. When you create an Oracle Text Context index, it creates some domain index tables. Apparently there is some change involved behind the scenes in the dripref.set_preferences procedure that perhaps does an append or some such thing. If you post this question in the Text space/sub-forum, with a link to this thread, you may get a more detailed explanation and perhaps a workaround from Oracle Text product manager Roger Ford or others. Or, perhaps some moderator will move this thread there.
