Oracle Text - procedure refreshing index doesn't run

Hi,
I'm experiencing problems refreshing an index using a procedure (see below). When running the command instead of the procedure everything is fine.
Reading through this forum I found that ctxapp role is needed, which I have. Since this didn't work the admin granted execute privileges on any procedures and programmes (for a short test). Even that didn't help.
The admin can run the procedure without any problems.
Help appreciated

---The procedure---
create or replace procedure indizes_erneuern
as
begin
ctx_ddl.optimize_index('ind_nachname_assistent', 'REBUILD');
end;---The error message

Oracle Text - CTX Context Index Soundex Problem

Hi,
I'm running into a problem with Oracle Text when searching using the ! (soundex) option. I've created a simple test example to highlight the issue.
Oracle Database 10g Enterprise Edition Release 10.2.0.4.0 - 64bit
Windows 2008 Server 64-bit
create table test_tab (test_col varchar2(200));
insert all
into test_tab (test_col) values ('ab-tönes')
into test_tab (test_col) values ('ab-tones')
into test_tab (test_col) values ('abtones')
into test_tab (test_col) values ('ab tones')
into test_tab (test_col) values ('ab-tanes')
select * from dual
select * from test_tab
begin
      ctx_ddl.create_preference ('test_lex1', 'basic_lexer');
      ctx_ddl.set_attribute ('test_lex1', 'whitespace', '/\|-_+&''');
      ctx_ddl.set_attribute('test_lex1','base_letter','YES');
      -- ctx_ddl.set_attribute('test_lex1','skipjoins','-');
end;
create index test_idx on test_tab (test_col)
indextype is ctxsys.context
    parameters
      ('lexer        test_lex1'
select token_text from dr$test_idx$i;
TOKEN_TEXT
AB
ABTONES
TANES
TONES
select * from test_tab where contains (test_col, '!ab tones') > 0;
TEST_COL
ab-tönes
ab-tones
ab tones
select * from test_tab where soundex(test_col) = soundex('ab tones');
TEST_COL
ab-tönes
ab-tones
abtones
ab tones
ab-tanes
So my question is, can anyone suggest an approach whereby I can get the Oracle Text Context index (or CTXCAT index if it's more appropriate) to return all 5 rows like the simple Soundex is doing?
I can't really use soundex as this search query will form part of a search screen for a multi-language application. Soundex is limited to English sounding words, so I need the solution to be able to compare strings that may not "sound" English.
It must be an attribute of the BASIC_LEXER, and I've tried skipjoins, start/end-joins, stop lists, but I just cannot get the Soundex feature of Oracle Text to function like the SOUNDEX() function!
Looking at how the tokens are stored dr$test_idx$i I need Oracle Text to almost concat 'AB' and 'TONES' to search as a single string.
Any help greatly appreciated.
Thanks,

I am not getting the same problem that you are getting with the umlat, but I don't see what is different. Please post the result of:
select ctx_report.create_index_script ('test_idx') from dual;
Here are the results on my system. Perhaps you can spot the difference. I added an empty_stoplist, so that it won't print out a long list of stopwords.

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.

Oracle Text, multi_column_datastore describe index

Referring to Re: Oracle Text, ctxsys.context problem with number column
In TOAD or SQL Navigator you can click on some object (like table, index) and click on tab "script" where is generated the code to create it.
Assuming that I am a person who sees the index for the first time where/how I can find multi_columns/parameters with which the index was created ?
For example:
exec ctx_ddl.drop_preference( 'myds' );
exec ctx_ddl.create_preference( 'myds', 'MULTI_COLUMN_DATASTORE' );
exec ctx_ddl.set_attribute( 'myds', 'COLUMNS', 'item_barcode, item_title, item_subtitle' );
CREATE INDEX i_index_test
   ON item (item_title)
   INDEXTYPE IS ctxsys.context
   PARAMETERS ( 'datastore myds' );And script says:
CREATE INDEX PLSQL.I_INDEX_TEST ON PLSQL.ITEM
(ITEM_TITLE)
INDEXTYPE IS CTXSYS.CONTEXT
PARAMETERS('datastore myds')
NOPARALLEL;
Where I can find datastore "myds" ?

You can use ctx_report to get all the information about an index.
I use it from SQL*Plus like this:
set pagesize 0
set heading off
set trimspool on
set long 500000
spool index.sql
select ctx_report.create_index_script('MyIndexName') from dual;
spool offThe only thing this won't give you is the source for any procedures used in the user_datastore. You can get that from user_sources.

Oracle Text location of Indexes

I am creating an Oracle Text index as per example given in documentation. I have set my storage preferences to point all the created tables / indexes to a given tablespace. This works fine, however I still get one index (domain) being created in the SYSTEM tablespace. Is this normal ? Can it be moved ?

The command used is
create index abstract_text_idx on abstracts(merge_text)
indextype is ctxsys.context
parameters('lexer abstract_lexer storage abstract_store memory 52428800')
The index left in SYSTEM tablespace is ABSTRACT_TEXT_IDX. All the DR$$ indexes have used the storage parameters in the abstract_store preference O.K.

Problem with blob column index created using Oracle Text.

Hi,
I'm running Oracle Database 10g 10.2.0.1.0 standard edition one, on windows server 2003 R2 x64.
I have a table with a blob column which contains pdf document.
Then, I create an index using the following script so that I can do fulltext search using Oracle Text.
CREATE INDEX DMCS.T_DMCS_FILE_DF_FILE_IDX ON DMCS.T_DMCS_FILE
(DF_FILE)
INDEXTYPE IS CTXSYS.CONTEXT
PARAMETERS('DATASTORE CTXSYS.DEFAULT_DATASTORE');
However, the index is not searchable and I check the following tables created by database for my index and found them to be empty as well !!
DR$T_DMCS_FILE_DF_FILE_IDX$I
DR$T_DMCS_FILE_DF_FILE_IDX$K
DR$T_DMCS_FILE_DF_FILE_IDX$N
DR$T_DMCS_FILE_DF_FILE_IDX$R
I wonder what's wrong with it.
My user has been granted the ctx_app role and I have other tables that store plain text which I use Oracle Text are fine. I even output the blob column and save as pdf file and they are fine.
However the database seems like not indexing my blob column although the index can be created without error.
Please advise.
Really appreciate anyone who can help.
Thank you.

The situation is I have already loaded a few pdf document into the table's blob column.
After I create the Oracle text index on this blob column, I find the system generated index tables listed in my earlier posting are empty, except for the 4th table.
Normally we'll see words inside the table where those are the words indexed by oracle text on my document.
As a result, no matter how i search for the index using select statement with contains operator, it will not give me any result.
I feel weird why the blob is not indexed. The content of the blob are actually valid because I tested this by export the content back to pdf and I can still view and search within the pdf.

Jap.

Problem creating Oracle text index

Oracle Text will not index the content inside the portlet of the pages. The portlet is treated as a portlet instance item and only the relevant attributes are searched for, like display name of the portlet, etc.

Does Oracle Text need to be "enabled"?

We want to start using Oracle Text. Does it need to be "enabled"? Any scripts that need to be run first?
Oracle version 10.1.0.4

Hi,
There is nothing to "enable" in order to use Oracle Text. But you need to create domain indexes(CONTEXT, CTXCAT, CTXRULE etc) depending on which features of Oracle Text you want to use. Also, in order to use some of the Oracle Text procedures and packages, you will need the CTXAPP role assigned to you.
Enjoy searching!

Oracle Text Help with XML column values

Hello. In addition to being new to Oracle Text, I am inheriting an Oracle Text application and have a couple of questions.
First, A context-based index has been set-up on a CLOB column which contains an XML formatted document. The Auto Section Group parameter has been set to created zones for each tag of the XML document. I have found that when using a browser to display the content of the CLOB, some of the column values have trouble displaying in the browser, where I receive an XML processing error. I believe this is due to the fact that some of the XML document rows contain URLs that are not embedded in the CDATA tag. In any case, if the browser has trouble displaying the XML, will oracle text have trouble indexing the XML and creating the section group zones?
Second, I understand that the NOT operator takes a right operand term and left operand term. Can either of the terms be the results of the WITHIN operator, i.e. "dogs not (cats within animals)".
Thank you.

I bet you just whipped that out, and I thank you with all my
heart, its amazing to me how many ways I tried to do what you did.
Thanks
I have a second question relating to the same problem and
that is in referencing the over state. Currently, I can write
'text' into the text field and see what I have coming in from xml
in its place during the 'up' state.
However, when the timeline hits the 'over' state, the
textfield will display nothing, or 'text' if I have that written
in. I suspect that I am not referencing the'over' state correctly.
Should I add one line of code sort of referencing the text
field and not just the button while in the over state?

Passing arrays to Oracle Stored procedure.

Have any body passed arrays to Oracle stored procedures while the app is running in Weblogic app server. I am able to pass the arrays with regular JDBC connection. If I run the same piece of code using a connection recieved from the datasource of weblogic server, its not working. I am getting serialization errors with the ArrayDescriptor class. Looks like the ArrayDescriptor is not serializable.
Does anybody know solution/workaround to pass arrays ?
Thanks in advance

you could write a wrapper class that extends ArrayDescriptor and implements serializable...
for example your class would look something like this.
public class MyArrayDescriptor extends ArrayDescriptor
implements Serializable
in your regular code use the wrapper class in place of the ArrayDescriptor (it will contain all the same methods as the real ArrayDescriptor) and you should be able to toss your wrapper class anywhere you please.

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,
OrauserN

How about check the following?

Index rules in oracle text and query using matches

Dear All,
I would like to ask about rules and matches function in oracle text.
I followed an example in oracle text application developer's guide.
I have a rule table like this :
1 oracle
2 larry or ellison
3 oracle and text
4 market share
then, I create an index to that table. This is needed for calling matches function. Here is the syntax :
create index queryx on queries(query_string)
indextype is ctxsys.ctxrule;
then, I noticed that the result on DR$QUERYX$I table as follows :
LARRY 0 2 2 1 (BLOB)
MARKET 0 4 4 1 (BLOB) {MARKET} {SHARE}
ORACLE 0 1 1 1 (BLOB)
ORACLE 0 3 3 1 (BLOB) {TEXT}
ELLISON 0 2 2 1 (BLOB)
What I want to ask is why doesn't the words 'share' and 'text' appear in the DR$QUERYX$ table?
When we use matches function, it then search on the index result and consequently it wion't find the 'share' word. so when for example I do query like this :
select query_id from queries where matches(query_string,' It only share ten percent of all products sold')>0
it will give 0 result since the no word in ' It only share ten percent of all products sold' was in index table. But actually it could possibly be categorized as the 4 category which rules is 'market share'
I tried this in a larger set of data and get same result.
Here is my generated rules from my document collection :
1 {REQUIREMENTS} & {ELICITATION}
1 {REQUIREMENTS} ~ {ELICITATION} & {ACTOR}

INTERPRETATION
so when I try to classify a document with the word ouline inside it, it should produce category 1 (based on the rules) but since there are no word 'outline' in index tabel, the matches will return 0 means that the document is not classifiedto any category. I don't understand why it happen. Anybody knows about this? I would really appreciate any help.
Thank you very much.

Hm, I see. It do make sense. so nice to know.
But then in the second example I gift where I used larger table, as shown below :
Here is my generated rules from my document collection :
1 {REQUIREMENTS} & {ELICITATION}
1 {REQUIREMENTS} ~ {ELICITATION} & {ACTOR}
1 {REQUIREMENTS} ~ {ELICITATION} ~ {ACTOR} & {FURPS}

2 {DESIGN} ~ {REPRESENTATION} ~ {MAY}
3 {PM} & {TESTING} & {ATTRIBUTI}
As far as I know, the sign ' ~ ' means 'OR' and '&' means 'and' . So based on the 4th line in my table :
1 {REQUIREMENTS} ~ {ELICITATION} ~ {ACTOR} ~ {FURPS} ~ {OUTLINE}
it can be concluded that if any of the words stated there been queried, so the category '1' will appear as a result. But then before we can use 'matches' to query it, we need ti create index for the rules table . I did it and the result were :
