CTXCAT index and VPD?

Hi all,
after looking into the logfile of IMPDP, i found this:
Failing sql is:
CREATE INDEX "Q1"."CTX1_AX_CODE" ON "Q1"."XREF" ("CODE") INDEXTYPE IS "CTXSYS"."CTXCAT" PARAMETERS ('STOPLIST CTXSYS.EMPTY_STOPLIST
             LEXER global_lexer
             WORDLIST global_wordlist
             STORAGE CTXSTORE')P
ORA-39083: Object type INDEX failed to create with error:
ORA-29855: error occurred in the execution of ODCIINDEXCREATE routine
ORA-20000: Oracle Text error:
DRG-50857: oracle error in drsxsopen
ORA-28100: policy function schema LICENSE is invalidI think the first 8 lines are saying some errors regarding ORACLE TEXT, and the last line is a VPD error, right?
it's confusing, how could an ORACLE TEXT index have anything to do with VPD? I don't see any relations between them.
anyone have any ideas?
thanks in advance

Hi,
Cause:
Starting with 10g CTXSYS no longer has DBA privileges. Traditionally, in previous releases, CTXSYS has been allowed to sync any index. But we have been moving toward the model that only the index owner or DBA can sync a given index.
Solution
To implement the solution, please upgrade to 11gR2, 11.2.0.2, where the problem is fixed.
Prior 11.2.0.2 you should change your PL/SQL code and use the owner of the index to SYNC, or a DBA user.

CTXSYS.CTXCAT index and CATSEARCH problem

I have table with just one column indexed (CBG_COMPANY_HOUSE_STREET_DIST) with CTXSYS.CTXCAT index. And the problem is that
words like 'OR', 'IF', 'MR', 'MRS', 'A' and some more like these are NOT INDEXED at all..! So simply when I try to use CATSEARCH like
select * from ros_dev.MAD_PLACES_DEDUPE where CATSEARCH(CBG_COMPANY_HOUSE_STREET_DIST,'MRS',null) > 0
I get no results at all...
What is the reason? What is the solution? Please, it is URGENT, I develope some software , I am not a DBA, and I have a deadline on Friday :(
Thanks for any help!

Ok - I just responded to your post over in the database forum. Same answer applies here. If you need help redoing the index, best to post here rather than the General Database forum though since it is definitely Text specific.
Thanks,
Ron

CONTEXT index vs a CTXCAT index

I'm puzzled as to which of these indexes is meant for what purpose. I like the auto-update feature of the CTXCAT index, so I'm leaning that direction.
Here's our situation. We have a table with about 2 million rows, where there's an EMPLOYER_NAME field. Users are constantly executing queries like:
where EMPLOYER_NAME like '%CHEVRON%'The CTXCAT index is also described as "Typically, with this index type, you index small documents or text fragments". I would consider this EMPLOYER_NAME column (VARCHAR2(50)) to fit this description, more or less.
The main thing that has me confused is that our vendor is pushing for a CONTEXT index, as they've got experience setting these up. We're not storing "text consists of large coherent documents.", but we are storing plain text.
Could someone offer some guidance? Thanks for your help,
--=Chuck

Depends on whether the words are predictable. You indicated in your first post they are employer names. If they are then presumably there is a table/list of valid values. Otherwise a CTX index may be your best shot but understand that you will be indexing every word and, I assume, most will be irrelevant.

Error while importing table having ctxcat index

Hi
I created a table and ctxcat index on the same. I exported the same. While importing, table got imported but for index creation it gave error imp-00017 with ora-29855.
Though the index have been created but with some errors. I can see the index in all_indexes table but if i try to see the entry in dba_segments, record is not found.
Seems that index is not created properly.
Pls suggest ASAP.
Regards
Rajiv

What's your source and target Oracle version ?
1) make sure context option is installed on target DB
2) create a user ctxsys, the schema where the context related objects resides

Ndata is new to Oracle 11g. Your other posts indicate that you are using Oracle 10g, so you don't have ndata, so you get an error when you try to use it. If you want to use the 11g features that enable context indexes with contains to do all of the things that ctxcat indexes with catsearch do, then you need to upgrade to 11g.
The online documentation is searchable. Most things regarding Oracle Text are contained in either the Oracle Text Reference or the Oracle Text Application Developer's guide.
I suggest that you start with something very simple, then build from there.
The following is similar to your other post that used catsearch:

CTXCAT index problem: SUBSTRING_INDEX parameter doesn't work

Hi,
I need a help with ctxcat index on Oracle 10g. I need to improve searching using CTXCAT index. All is working quite well except SUBSTRING_INDEX parameter. I thought that following was necessary and sufficient:
EXEC ctx_ddl.create_preference('KEVFT_WL', 'BASIC_WORDLIST');
EXEC ctx_ddl.set_attribute('KEVFT_WL', 'substring_index', 'YES');
EXEC ctx_ddl.set_attribute('KEVFT_WL', 'prefix_index', 'YES');
EXEC ctx_ddl.set_attribute('KEVFT_WL', 'prefix_min_length', 1);
EXEC ctx_ddl.set_attribute('KEVFT_WL', 'prefix_max_length', 6);
This BASIC_WORDLIST preference set is used for index creation. But the problem is, that when I try to search using query:
SELECT * FROM TMP_FULLTEXT
WHERE CATSEARCH(fulltext, '%abc', null)> 0;
then I get no rows in results. Despite the fact that row with the text 'aabc' exists in the table.
Can anyone tell me what the problem is?
Thank you,
Julius Chrobak

With a catsearch query operator, the wildcard is an asterisk (*), not a percent sign (%) as with a contains query operator. However, even with the correct wildcard, left truncation is not supported with ctxcat. However, if you use a query template, then you can use the context grammar with the % wildcard for context grammar and left truncation is supported. Please see the demonstration below that reproduces the problem, then corrects it.

Error when hit ctxsys.ctxcat index

I use SQL query to generated report page in HTML DB, the query hit Oracle ctxsys.ctxcat indexes, after sent query, I got this error message. My question is: Does HTML DB support ctxsys.ctxcat index?
report error:
ORA-20000: Oracle Text error:
DRG-10849: catsearch does not support functional invocation
My sample query:
SELECT distinct(FEATURE_ID),
FEATURE_NAME
from maint_query_view
where FEATURE_NAME_OFFICIAL = 'Y'
and feature_id in (select feature_id from maint_query_view
where (catsearch(:FEATURENAME, 'index',null)>0);
Thanks
Lei

Lei,
1) HTML DB does support the CTXCAT index type.
2) The error you've encountered seems specific to Oracle Text and not HTML DB (I would suspect you would encounter the same error if you issued the query from SQL*Plus).
It's best to file a TAR with Oracle Worldwide Support on this one.

Ctxcat index supporting multicolumn datastore

I've been looking to see if a ctxcat index supports something like a multicolumn datastore.
What I'm trying to do is to search multiple columns (all 256 bytes in size or less) using a like query on each of those columns with the result being ordered by up to 3 different non searched columns
For example, the book scenerio
A table with the following columns
title
publisher
author
publication_date
quantity
location
I want to be able to search on title, publisher, and author all at once (optionally searching the tokens with % symbols), and then sorting on publication_date, quantity and location.
Now doing the context index, it worked fine, until I started ordering the results. Straight "like" queries with the ordering were returning quicker.
So I've started looking at ctxcat indexes to provide the flexibility of mixed query searching using the "order by" in the catsearch function.
The question is, how do I setup and search all three columns(title, publisher, author) at once with ctxcat index? Since ctxcat indexes don't support support the datastore option, how do you search on multi-columns? Do I need to make a concatenated column with title, publisher and author, or is there something in the configuration of the ctxcat index that I'm missing?

i have exactly the same situation - that is i need to search on four columns and am trying to use ctxcat ...
but the twist i have is - based on what coulmns the user wants to search - i want to limit the serach to ONLY those columns
Is there some way to do that using ctxcat ? ... other than creating a large number of extra columns containing different combinations of searchable columns... yikes ... wont even go there ....

CTXCAT index support MULTI_COLUMN_DATASTORE?

I've been using a CONTEXT index in my app, however, having to re-synchronize the index is an issue with my high insert rate. So, I'm considering using a CTXCAT since all db updates are transactional.
However, my CONTEXT query uses a MULTI_COLUMN_DATASTORE to query multiple columns via the concatenated column and it doesn't look like the CTXCAT index will support MULTI_COLUMN_DATASTORE? Does anyone know?
If the MULTI_COLUMN_DATASTORE is not supported, is there an alternative query I could use whilst still being able to use CTXCAT index?
Many thanks!

Hi David,
Until you get to 10g would a job that sync's frequently work? It sounds like the new sync on commit is what you need (provided it wouldn't cause performance problems for you), so would the job be an acceptable workaround until you upgrade?

Create CTXCAT index in parallel mode

I am using Oracle Database 11g Enterprise Edition Release 11.2.0.2.0 - 64bit Production with oracle text version 11.2.0.2.0.
Following script is used to create the ctxcat index but I noticed it is not creating the index in parallel. We have 16 cpu server. The table onto which text index is created has no partition.

What should be done to create this index in parallel? Is there any other thing that can be done to speed up creation without disabling prefix index.
Thanks. I appreciate you time and effort.

Hi,
in the manual some remarks are made for parallel indexing, see http://download.oracle.com/docs/cd/E14072_01/text.112/e10945/ind.htm#CIHCBABI
So it is possible to index in parallel, but you don't have control, the oracle db decides this for you. So it is possible that Oracle thinks that single indexing is faster, more work is done in the database besides the index creation, and many more factors (also mentioned in above document).
I did many parallel indexing on systems, but always on quiet moments, so I have the most resources for creating indexes. Furthermore I noticed that system statistics can influence the creation. If the statistics are good for the CPU and I/O, the parallel creation can be optimised by the db.

What is diff b/w sy-index and sy-tabix

Hi all,
Can u plz give me the diff b/w sy-index and sy-tabix exactly and how it works.
Thanks & Regards
Venkat

Hi Venkat,
1.SY-INDEX
->Current loop pass
->In a DO or WHILE loop, SY-INDEX contains the number of loop passes including the current pass.
2.SY-TABIX
->Current line index
Current line of an internal table. SY-TABIX is set by the statements below, but only for index tables.
The field is either not set or is set to 0 for hashed tables.
APPEND sets SY-TABIX to the index of the last line of the table, that is, it contains the overall number of entries in the table.

COLLECT sets SY-TABIX to the index of the existing or inserted line in the table. If the table has the type HASHED TABLE, SY-TABIX is set to 0.
LOOP AT sets SY-TABIX to the index of the current line at the beginning of each loop lass. At the end of the loop, SY-TABIX is reset to the value that it had before entering the loop. It is set to 0 if the table has the type HASHED TABLE.
READ TABLE sets SY-TABIX to the index of the table line read. If you use a binary search, and the system does not find a line, SY-TABIX contains the total number of lines, or one more than the total number of lines. SY-INDEX is undefined if a linear search fails to return an entry.

SEARCH <itab> FOR sets SY-TABIX to the index of the table line in which the search string is found.
I think that it clears ur doubt.
Thanks,

What is difference between sy-index and sy-tabix and where both are using ?

what is difference between sy-index and sy-tabix and where both are using ?

hi nagaraju
sy-tabix is in Internal table, current line index. So it can only be used while looping at the internal table.
sy-index is in Loops, number of current pass. This you can use in other loop statements also (like do-enddo loop, while-endwhile)
SY-INDEX is a counter for following loops: do...enddo, while..endwhile
SY-TABIX is a counter for LOOP...ENDLOOP, READ TABLE...
Here is an example from which you can understand the difference between sy-tabix and sy-index.
Itab is an internal table with the following data in it.
id Name
198 XYZ
475 ABC
545 PQR.
loop at itab where id > 300.
write :/ itab-id, itab-name , sy-tabix, sy-index.
endloop.
My output will be :
475 ABC 2 1
545 PQR 3 2
Sy-tabix is the index of the record in internal table.
sy-index gives the no of times of loop passes.
So, for the first record in the output (475 ABC), 2 is the index of the record in internal table and as it is first time loop pass occured, sy-index value is 1.

Difference b/w sy-index and sy-tabix

hai all,
Could u explain the difference b/w sy-index and sy-tabix?
regards,
Selva

Hi,
sy-index - For Loops, Current Loop Pass.
sy-tabix - For Internal Table, Current Line Index in internal table.
sy-tabix is used at internal table operations (READ TABLE ... LOOP AT ...), sy-index is used at cycles (DO...n TIMES).
SY-TABIX:
Current line of an internal table. SY-TABIX is set by the statements below, but only for index tables. The field is either not set or is set to 0 for hashed tables.
it can be set by using the following:
1.append
2.collect
3.loop at
4. read
5.search
APPEND sets SY-TABIX to the index of the last line of the table, that is, it contains the overall number of entries in the table.
COLLECT sets SY-TABIX to the index of the existing or inserted line in the table. If the table has the type HASHED TABLE, SY-TABIX is set to 0.
LOOP AT sets SY-TABIX to the index of the current line at the beginning of each loop lass. At the end of the loop, SY-TABIX is reset to the value that it had before entering the loop. It is set to 0 if the table has the type HASHED TABLE.
READ TABLE sets SY-TABIX to the index of the table line read. If you use a binary search, and the system does not find a line, SY-TABIX contains the total number of lines, or one more than the total number of lines. SY-INDEX is undefined if a linear search fails to return an entry.
SEARCH <itab> FOR sets SY-TABIX to the index of the table line in which the search string is found.
SY-INDEX:
SY-INDEX is used to describe the number of iteration with in the DO..ENDDO, WHILE ...ENDWHILE....
for example,
DO.
WRITE SY-INDEX.
IF SY-INDEX = 3.
EXIT.
ENDIF.
ENDDO.
it gives output as:
1 2 3

SEARCH FOR sets SY-TABIX to the index of the table line in which the search string is found.
SY_INDEX - In a DO or WHILE loop, SY-INDEX contains the number of loop passes including the current pass.
sy-tabix is the tab index - the index of the record in the internal table you are accessing,
sy-index is the loop counter.
If you use a condition in LOOP the sy-index will go from 1 to n, but sy-tabix will refer to the line in the internal table.
Hope this helps u.
