CTX_DDL.SYNC_

ctx_ddl.sync_index(index_name) and have not been able to get it to work. Are you suppose
to "exec" it or use the "@".

I have use the exec and it still does not work I get the error

Trigger calling ctx_ddl.sync_index problem

Dear,
In order to keep my context indexes up-to-date, I'm trying to write a trigger calling this PL/SQL procedure on update/insert/delete statement.
However, there must be a problem in my trigger definition since it gives compilation errors! I don't see what 's wrong!
This is my trigger definition:
=========BEGIN==================
create or replace trigger update_lexicon_expl_nl after insert or delete or update on lexicon begin execute ctx_ddl.sync_index('lexicon_expl_nl'); end;
=========END===================
The compilation error is something like:
"Encountered ctx_ddl when expecting one of the following :=.(@;immediate"
PS. calling 'execute ctx_ddl.sync('myindex') in SQL Plus is workigng OK
Please help.
Dirk

You do not need to trigger that table,there are two way to 'update' index.
1.Alter index your_index_name rebuild.
2.Set up background DML process, which need you work with an DBA or you have ctxsys role.

Calling CTX_DDL.SYNC_INDEX Package but reflected

Hi All,
I have a table Customer_Tif_Detail which is having   9383428 rows:
select count(*) from Customer_Tif_Detail;
COUNT(*)
9383428
And I have a query which taking too much time to execute, below is teh query:
Select ZIP_STATUS From Customer_Tif_Detail Ctd Where Ctd.Tif_Name Like '%231079_0068.tif%'
AND 0= ( select count(*) as CNT From Customer_Document_Detail Cdd Where Cdd.Tif_End Is Null
And cdd.id = ctd.id AND Cdd.Submit_Flag = 'Y');
Then I created a Index Type Index, below is the process I did:
BEGIN
     CTX_DDL.CREATE_PREFERENCE ('tif_details', 'BASIC_LEXER');
    CTX_DDL.SET_ATTRIBUTE ('tif_details', 'PRINTJOINS', '_.');
   END;
CREATE INDEX idx_customer_tif_name ON Customer_Tif_Detail(tif_name) INDEXTYPE IS CTXSYS.CONTEXT
   PARAMETERS ('LEXER tif_details');
And I am using below query with using contains, below is query:
Select ZIP_STATUS From Customer_Tif_Detail Ctd Where Ctd.Tif_Name contains(tif_name, '%231079_0068.tif%' )
AND 0= ( select count(*) as CNT From Customer_Document_Detail Cdd Where Cdd.Tif_End Is Null
And cdd.id = ctd.id AND Cdd.Submit_Flag = 'Y');
Now its working fine, but when I check from below query them I am gettimg lot of missing data from index:
select count(*) from dr$IDX_TIF_NAME_CTX$i;
COUNT(*)
7953605
Even I used below CTX_DDL.SYNC_INDEX package to do syncronization even I am getting same records:
   call CTX_DDL.SYNC_INDEX('idx_customer_tif_name', '1073741824');
what I am missing here to do proper syncronization between index and original data?
and how miuch memory I need to apply after some insertion goes on Customer_Tif_Detail table to syncronization index on CTX_DDL.SYNC_INDEX package?
Thanks

What is the result of;
select count(DISTINCT tif_name) from Customer_Tif_Detail;

CTX_DDL.SYNC_INDEX gives ORA-03113 error

I am trying to use the CTX_DDL.SYNC_INDEX command in order to update the full Text Index on a table, which contains a word document as a binary object, but I get an ORA-03113 error every time I do this. I get the same error if the table contains an Excel file. It works perfectly OK if the table contains simple text files.

Hi Barbara - thanks for your response.
In answer to your questions;
Oracle version is 9.2.0.1.0
Table structure is created with following sql;
CREATE TABLE DOCUMENTFILE
     (DOCUMENTFILEID      NUMBER (10,0) NOT NULL,
     DATA                LONG RAW,

Ctx_ddl.sync_index problem

Hi,
When I try to use the ctx_ddl.syn_index procedure to synchronize index I've got the following error:
ERROR at line 1:
ORA-20000: Oracle Text error:

I think that a main reason of the error that procedure AllocateDocids tries to return this value through P_STARTID parameter or use this variable to store a value from the above-mentioned query. As appears from documentation the limit of BINARY_INTEGER is 2147483647, so we have exception "numeric overflow".
Is I am right in conclusions? If yes, is there any workaround to eliminate this error?
Thanks.

I would appear you've exceeded the docid limit of 2 billion. That can only happen if you have more than 2 billion rows added or updated in your table.
Is this likely? Is this a very highly-used table with a huge number of updates?
The only solution here is to rebuild the index so that allocates new docid values throughout. If the table is large, that obviously could take a while. Is this 11g? If so you can use the "recreate index offline" feature.

Will frequent execution of CTX_DDL.SYNC_INDEX causes slow performance

Hi:
We currently execute CTX_DDL.SYNC_INDEX every 5 mins (using a DBMS_JOB) to synchronize oracle text indexes on VARCHAR2 columns. We are planning on increasing the frequency to 1 min. It looks like performance will not be impacted based on the information in http://download.oracle.com/docs/html/A95995_01/oraclete.htm.
My question is has anyone seen database performance problems after increasing the frequency of sync_index.
Thanks!

Hi,
our load is not that big, about 1500 new documents (stored in blob) and about 250 updates on documents. The size varies between 2k and 50MB. Even the biggest one goes fast although "Sync on commit". About 10 seconds to insert and index. BTW running on AIX 5.3 and Oracle 10.2.0.3. What helps in this indexing that we made the parameter for memory for text indexes increased to 128MB.

Is ctx_ddl.sync_index an offline operation?

Sorry if the answer to this is staring at me in the documentation: I couldn't find it if so.
We run Standard Edition 11.2.0.1, so RECREATE_INDEX_ONLINE is not available to us.
Instead, we regularly (about every 2 hours) use ctx_ddl.sync_index to get our Text index to pick up new arrivals in the underlying table.
My question is where ctx_ddl.sync_index is an online operation or not? Does the table become unsearchable whilst it's happening, in other words? Our resyncs take about 8 seconds to complete, and I haven't been able to test for this because if there is an outage, it's over too quickly to spot. But there's talk about us resyncing more frequently -so if it does make the thing unsearchable for even a few seconds, I think we need to know that!

See "3.5 Managing DML Operations for a CONTEXT Index"
at http://download.oracle.com/docs/cd/E11882_01/text.112/e16594/ind.htm#i1007544
and "SYNC_INDEX"
at http://download.oracle.com/docs/cd/E11882_01/text.112/e16593/cddlpkg.htm#CCREF0652
Yes, reading them doesn't make it clear the the existing index is usable, queryable while a Sync is running.
However, it is apparent that new entries from DML are not visible in the index until the SYNC_INDEX is done. The SYNC_INDEX commits new entries in batches -- so it is concurrent with existing entries being queryable.
Your Text Indexes may need periodic re-optimization.
see "OPTIMIZE_INDEX"
at http://download.oracle.com/docs/cd/E11882_01/text.112/e16593/cddlpkg.htm#i998200
(OTOH : DROP and CREATE is something which you wouldn't do !)
Text Indexes aren't really "index structures" in the manner of, say, regular B-Tree indexes. They are actually "Tables" that are seen as Indexes -- somewhat like "Lookup Tables".
(The last time I worked with Text Indexes was in 8.1.7 , but 11.2 doesn't negate any of my knowledge of Text Indexes).

CTX_DDL.SYNC_INDEX 'memory' argument

According to the Oracle Text manual,
http://download.oracle.com/docs/cd/B28359_01/text.111/b28304/cddlpkg.htm#i998469
The memory parameter specifies the amount of memory Oracle Text uses for the synchronization operation before flushing the index to disk.
Does this memory come out of the shared pool, or the PGA?
I want to allocate as much memory as possible for a one-time index sync following a massive data intake, but I need to know where the memory is coming from.
Thanks

According to the Performance FAQ,
http://www.oracle.com/technology/products/text/x/faqs/imt_perf_faq.html#q21
It helps to size your SGA downward during an index rebuild to make more room for the indexing process. So the 'memory' referred to in CTX_DDL.SYNC_INDEX must be external to the SGA. That's what I needed to know.

Ctx_ddl.sync_index

The sql below synchronizes all the pending context:
set echo off
set heading off
set feedback off
set pagesize 50000
spool c:\sync.sql
select distinct 'exec ctx_ddl.sync_index(''' || PND_INDEX_OWNER || '.' || PND_INDEX_NAME || ''')' from ctx_pending;
spool off
@c:\sync.sql;
Would it be possible to transform the above code into a procedure?
So I could run that procedure at regular intervals using dbms_job ?
Can Anyone translate the above into a procedure ?
Thanks.

I've received the procedure from a college:
create or replace procedure sync_context
is
begin
for s_rec in
(select distinct pnd_index_owner, pnd_index_name
from ctx_pending) loop
execute immediate 'begin ctx_ddl.sync_index('''||s_rec.pnd_index_owner||'.'||s_rec.pnd_index_name||'''); end;';
end loop;
end;
Extra Question:
As user ctxsys it should be sufficient to execute ctx_dll.sync_index to sync all pending context
but this does not seem to work properly ??

Can HTMLDB 1.6 run without CTX_DDL?

Our database is Oracle 9.03 on an alpha VMS machine.
My DBA says that there are security problems with CTX_DDL on that version and platform. We cannot install CTX_DDL until she applies patches to the database (an arduous task).
I know the WWV_FLOW_HELP depends on CTX.
Will HTMLDB 1.6 run without the CTX packages (even with no help)?

Cyril,
Surprisingly, Oracle Text is not listed as an installation prerequisite like Oracle XML DB. It probably should be, but that's the future.
To answer your question "will HTML DB 1.6 run without the CTX packages", that answer to that is yes. A few things that won't work that I can think of are 1) warning issued during installation of HTML DB for grant of CTX_DDL 2) Presidential demonstration won't work and/or install, 3) searchable online help will fail, 4) any application which makes use of Oracle Text functionality will fail.
Ultimately, you should try to install Oracle Text in this database to avoid these errors. But applications you build before then should work just fine.

Ctx_ddl.optimize_index in dbms_job

I am trying to set up the jobs to optimize our various interMedia indexes at night, but am having an issue with ownership. The index exists in the user_a schema. As CTXSYS, I can successfully:
ctx_ddl.optimize_index('USER_A.INDEX_NAME', 'full');even with 'set role none' in force.
But if I submit this as a job under CTXSYS, the job fails (putting an entry in the alert log) with a DRG-10016 (I'm pretty sure this was the error number) saying that CTXSYS needs to be the owner of the object to modify the object.
Why can I do the ctx_ddl.optimize_index at a SQL*Plus prompt with 'set role none' and not through a job?
Also, is it correct to set up this job as CTXSYS instead of USER_A? USER_A cannot even execute CTX_DDL in a job without a direct grant - and I haven't seen any examples saying this is the way to do it.

As a general rule, you should never update any data dictionary directly. There may be unknown cascading effects and Oracle does not offer support once you have modified a data dictionary directly.

NLS_LENGTH_SEMANTIC = 'CHAR ' and ctx_ddl.add_sub_lexer

Hi
I have Oracle 9.2.1. The NLS_LENGTH_SEMANTIC is set to 'CHAR '. When i call the procedure
call ctx_ddl.add_sub_lexer('global_lexer','english','english_lexer','en')
to create a lexer i am getting error
The following error has occurred:
ORA-06502: PL/SQL: numeric or value error
ORA-06512: at line 1
If NLS_LENGTH_SEMANTIC is BYTE everything works fine.
Please help ASAP.
Thanks

When you say the lexer can be created using NLS_LENGTH_SEMANTIC=BYTE but not CHAR. Are you referring to the NLS_LENGTH_SEMANTIC setting at the sesssion level, system level or at the CREATE DATABASE level?
Which version of the database are you running on? And what was the value of NLS_LENGTH_SEMANTIC when Oracle Text was installed?

Explanation needed for how CTX_DDL.ADD_MDATA_SECTION works

I am having difficulty understanding conceptually how the CTX_DDL.ADD_MDATA_SECTION procedure works. Its arguments are group name, section and tag. The group name I understand. What I don't understand is why is there both a section and tag arguments.
The example in the documentation is:
ctx_ddl.create.section.group('htmgroup', 'HTML_SECTION_GROUP');
ctx_ddl.add_mdata_section('htmgroup', 'author', 'Gordon Burn');
which the documentation explains
creates an MDATA section called AUTHOR and gives it the value Gordon Burn (author of the novel Alma).
I tried this example though with a basic_group and section called title and a tag called title. I then tried to search with CONTAINS(my_column, 'MDATA(title, title)') > 0 yet I did not get results. When I used the CTX_DDL.ADD_MDATA and added the word title I got back results.
What is the significance of the tag argument in ADD_MDATA_SECTION? You cannot search on it and furthermore you don't use it in ADD_MDATA, you only use the section_name.

It is difficult to understand exactly what you did without a full example and having only one tag with the same name as your section adds to the confusion. Please see if the following example, where I have used a fiction_titles tag and a computer_titles tag, makes things clearer. If it is still not clear, then please provide a copy and paste.
