Intermedia Text/Hide Tags.

I use intermedia text to store files with tags like internet (i.e <Start> bla ..</End>.
I use developer 6 to search and retrive information, but developer show me the tags,
How can I do to hide the tags?
Thanks for the help.

Problems clause within (Intermedia text)

I have problems using the clause within in a XML file. I suspect that is impossible for the intermedia text to find words within tags with attributes, could you help me, my friend?
Thanks a lot.
And Merry Christmas.

Hi Ralf,
please define first your own preferences like this:
exec CTX_DDL.drop_preference('MY_LEXER');
exec CTX_DDL.create_preference('MY_LEXER','BASIC_LEXER');
exec CTX_DDL.set_attribute('MY_LEXER','ALTERNATE_SPELLING',
'GERMAN');
exec CTX_DDL.set_attribute('MY_LEXER','BASE_LETTER','YES');
exec CTX_DDL.set_attribute('MY_LEXER','MIXED_CASE', 'NO');

exec ctx_ddl.Create_Preference ('MY_FILTER','NULL_FILTER');
exec ctx_ddl.drop_section_group ('MY_SECTION');
exec ctx_ddl.create_section_group
('MY_SECTION','NULL_SECTION_GROUP');
and then create your index with this preferences. You only need
an INSO filter if you want to index pdf,word,...
create index test.alldocs_ctx on test.alldocs(data)
     indextype is ctxsys.context
     parameters ('DATASTORE CTXSYS.MyUserDS FILTER
CTXSYS.INSO_FILTER LEXER BASIC_LEXER');create index test.alldocs_ctx on test.alldocs(data)
     indextype is ctxsys.context
     parameters ('
DATASTORE CTXSYS.MyUserDS
lexer MY_LEXER
filter MY_FILTER
section group MY_SECTION');
Then see in the token table what tokens are in the index:
select token_text from dr$alldocs_ctx$i;
If you got also an ORA-3113 see in alert.log if there is a trace
referenced with this error and have a look in this file to find a
better error message.
Good luck.

How do I use XSLT & XML is stored in InterMedia Text.....

I use interMedia Text to store XML document. How do I use the XSLT Processor API to transform the data which is searched by XML SQL Utility??
//***Source Code
public Document xmlquery(String tabName,String xslfilename)
Document xmlDocToReturn = null;
String xmlString;
try
DriverManager.registerDriver(new oracle.jdbc.driver.OracleDriver());
//initiate a JDBC connection
// initialize the OracleXMLQuery
OracleXMLQuery qry = new OracleXMLQuery(conn,"select XML_TEXT from bookstore where contains (xml_text,'John WITHIN authorsec')>0");
// structure the generated XML document
qry.setMaxRows(2);
// set the maximum number of rows to be returned
// get the XML document in string format
xmlString = qry.getXMLString();
// print out the XML document
System.out.println(" OUTPUT IS:\n"+xmlString);
// get the XML document in string format
xmlDocToReturn = qry.getXMLDOM();
conn.close();
catch (SQLException e) {
return xmlDocToReturn;
xml = (XMLDocument)query.xmlquery(args[1],args[0]);
// Instantiate the stylesheet
XSLStylesheet xsl = new XSLStylesheet(xsldoc, xslURL);
XSLProcessor processor = new XSLProcessor();
// Display any warnings that may occur
processor.showWarnings(true);
processor.setErrorStream(System.err);
// Process XSL
DocumentFragment result = processor.processXSL(xsl, xml);
Thank you.

Your problem here is that when you store an XML document in a CLOB and search it using intermedia, when you do a query like:
SELECT xml_text
FROM bookstore
WHERE CONTAINS(xml_text,'John WITHIN authorsec')>0
The output from the XML SQL Utility using getXMLDOM() looks like this:<ROWSET>
<ROW>
<XML_TEXT><![CDATA[
<bookstuff>
<authorsec>
<name>Steve</name>
</authorsec>
etc.
</bookstuff>
]]>
</XML_TEXT>
</ROW>
</ROWSET>with the document as a single text value (it's actually just a text node, not a CDATA node) but the above illustrates conceptually that the whole XML document is one big text node.
To transform this you'll need to parse that XML text into an XML document in memory by passing constructing a StringReader() on the text value and parsing that reader.

InterMedia Text with USER_DATASTORE and ORA-03113

Hi,
I have problems using Oracle's InterMedia Text-index with a
USER_DATASTORE. I'm using Oracle 8.1.7 on Windows NT 4.0.
What I try to do is to create a context-index on multiple columns
of multiple tables. I created a table containing the original
tablenames and primary keys plus a char(1)-column to index, a
user_datastore, a procedure in a user-schema, a
wrapping-procedure in ctxsys' schema and finally the index. All
works fine so far but I get an ORA-03113 "end-of-file on
communication channel" error when querying the table with
contains. The procedure itself works.
Here's what I tried in detail:
I created a table "alldocs" containing the tablename and
primary-key-value of each line of each table plus a dummy-column
for the index:
create table alldocs(
table varchar2(30) not null,
id number not null,
data char(1),
primary key(tabelle, id)
I filled this table:
insert into alldocs (select 'MYDOCS', id, 'a' from mydocs);
insert into alldocs (select 'OTHERDOCS', id, 'b' from otherdocs);
The user's procedure - only dummy for testing - is:
create procedure test.GetAllDocsData(row IN ROWID, data IN OUT
NOCOPY CLOB) IS
     tabname varchar2(30);
     myid     number;
     tmpclob clob;
begin
     dbms_lob.createtemporary(tmpclob, TRUE);
     dbms_lob.writeappend(tmpclob, 34, 'Ein Text mit ca. 20
Zeichen Ldnge.');
     data := tmpclob;
end;
In ctxsys' schema I defined the following procedure and the
datastore:
create or replace procedure sysGetAllDocsData(rid in rowid, tlob
in out clob) is
begin
test.GetAllDocsData(rid, tlob);
end sysGetAllDocsData;
grant execute on sysGetAllDocsData to test;
call ctx_ddl.create_preference('MyUserDS', 'user_datastore');
call ctx_ddl.set_attribute('MyUserDS', 'procedure',
'sysGetAllDocsData');
call ctx_ddl.set_attribute('MyUserDS', 'output_type', 'CLOB');
Finally I defined the index:
create index test.alldocs_ctx on test.alldocs(data)
     indextype is ctxsys.context
     parameters ('DATASTORE CTXSYS.MyUserDS FILTER
CTXSYS.INSO_FILTER LEXER BASIC_LEXER');
This all works without errors. But when querying like this:
select * from test.alldocs where contains('data', 'Text')>0
the answer is
ORA-03113: end-of-file on communication channel
I hope someone can help.

Using intermedia text

Hello,
I'm working on a website at the moment which is cgi based and has an Oracle 8i backend.
On this website users can upload word documents etc into an knowledge base. These documents are physically held on the file system
What I want to do is to upload the documents to an Oracle table and then use intermedia text to search on these documents. I would like to avail of intermedia Themes & Gists and the "ranking" system it uses. In other words I would like the search to return something similar to the search results you find in Oracle Portal.
Any information on how to incorporate oracle intermedia into an existing cgi based website would be much appreciated.
thank you.

Hi,
For documentation see here on technet: products -> Oracle Text.
You don't have to load the documents into the database when they are already in the filesystem.
You can create a table with an entry for each filename.
Here is a sample script for FILE_DATASTORE with INSO FILTER (for filtering word and other documents).
=========================================================

drop table datastores;
create table datastores(id number primary key, docs varchar2(2000));

Using InterMedia Text with FrameMaker, StarOffice...

I'm planning to use InterMedia text with various kinds of documents, but inso filter does not support them. In particular, it does not support:
- Framemaker
- PostScript (I know it works on encapsulated PostScript)
- Applix
Where can I find the right filters?
Is there a way to use InterMedia text with these documents?
Thank you
Paolo Bonanomi

I'd suggest searching the web - there are a number of little freeware filters out there that could be used as user-filters.>Have anybody found a postscript filter and can post it here ?

InterMedia Text Search results

We have interMedia Text enabled on our 3.0.9.8.2 install and, for Search Results, I need to understand how the percentage score is calculated and, if results have the same score, how the order is determined. Is it possible to reorder the results because it appears to be random? Can anyone point me to the relevant documentation?

So Stephen, if I understand correctly, you have URL items, where the URL references the content in the IFS repository. This means that these items are being indexed by the WWSBR_URL_CTX_INDX. It'd be interesting to see if the results are returned as you would expect them to be using this index alone. This will tell you if there is a problem with Intermedia Text or if the problem lies with the way that Portal is using Intermedia Text and combining the scores from the multiple indexes.
Try running a SQL query like
select i.title, score(10) scr from wwv_things i, wwsbr_url$ u
where i.id=u.object_id
and contains (u.absolute_url,'${oracle}',10) > 0
order by scr desc
This will match your search term against only text which was indexed by the URL index and returns the display name of the corresponding item. Here I've searched for the term 'oracle'; change this to whatever you were using in your testcase. Note also that the $ implies the stem operator which is used by default in Portal.
If this query doesn't return you the scores that you were expecting then the problem is to do with the way that Intermedia Text is indexing your PDF documents. If it does return what you'd expect then we need to look more closely at what Portal is doing with the scores.

Is the listener up and running?
Installation
1.What are the steps to install interMedia Text manually, AFTER installing the code via the
installer?
A.
cd $ORACLE_HOME/ctx/admin
B. as SYS:
@dr0csys.sql ctxsys system temp
where ctxsys is the ctxsys password
system is the default tablespace for ctxsys
temp is the temporary tablespace for ctxsys
C. as CTXSYS:
@dr0inst.sql
/oracle/db/dev118/ctx/lib/libctxx8.so
(on Solaris)
where /oracle/db/dev118 is $ORACLE_HOME
D. as CTXSYS:
@defaults/drdefus.sql
Note: this is assuming you want U.S. to be your language default, otherwise run the
corresponding drdef for your language.
2.What are the steps to install interMedia Text manually, with a Net8 Configuration?
A. Configure an IPC listener address.
For example, change:
LISTENER =
(ADDRESS_LIST=
(ADDRESS=
(PROTOCOL=tcp) (HOST=ap118sun.us.oracle.com) (PORT=1521)
to:
LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = IPC) (KEY = EXTPROC0))
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP) (HOST = ap118sun) (PORT
=1521))
This shows the full LISTENER definition in your listener.ora. Note: EXTPROC0 ends in a
zero.
B. Add a system identifier (SID) name of PLSExtProc and a program name of EXTPROC in the server's LISTENER.ORA file.
For example, in the SID_LIST_LISTENER definition, insert:
SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC = ...
(SID_DESC =
(SID_NAME=PLSExtProc)(ORACLE_HOME=/oracle/db/dev118)
(PROGRAM=extproc)
C. Add a net service name description entry for EXTPROC0 in the server's tnsnames.ora
file, using SID rather than SERVICE_NAME in the CONNECT_DATA section.
For example, add this to the end of tnsnames.ora:
extproc_connection_data =
(DESCRIPTION=
(ADDRESS_LIST =
(ADDRESS=(PROTOCOL=IPC)(KEY=EXTPROC0))
(CONNECT_DATA=
(SID=PLSExtProc)
(PRESENTATION = RO)
This entry should be added exactly as you see it here (do NOT substitute your SID
anywhere, do NOT change the case of any text). Note: EXTPROC0 ends in a zero, RO
ends in an Oh
1.How do I check my interMedia Text installation and setup?
A.
lsnrct1status
should give you the following:

Services Summary...
PLSExtProc has 1 service handler(s)
oco815 has 3 service handler(s)
The command completed successfully
The important information to understand here is the service handler for PLSExtProc.
B. Create a user/table/index/query thus:
As SYS or SYSTEM:
create user ctxtest identified by ctxtest ;
grant connect, resource, ctxapp to ctxtest ;
Do any other grants, quotas, tablespace etc. for the new user. As CTXTEST:
create table quick
quick_id number primary key,
text varchar(80)
insert into quick ( quick_id, text )
values ( 1, 'The cat sat on the mat' );
insert into quick ( quick_id, text )
values ( 2, 'The quick brown fox jumped over the lazy dog' );
commit;
create index quick_text on quick ( text )
indextype is ctxsys.context;
At this point, if your Net8 setup is NOT correct you will get:
create index quick_text on quick ( text )
ERROR at line 1:
ORA-29855: error occurred in the execution of ODCIINDEXCREATE routine
ORA-20000: ConText error:
DRG-50704: Net8 listener is not running or cannot start external procedures

ORA-06512: at "CTXSYS.DRUE", line 122
ORA-06512: at "CTXSYS.TEXTINDEXMETHODS", line 34
ORA-06512: at line 1
If everything is OK, you will get:
Index created.
Now try some queries:
SQL> select quick_id from quick where contains(text, 'cat')>0;
QUICK_ID
1
SQL> select quick_id from quick where contains(text, 'fox')>0;
QUICK_ID
2
Congratulations !! You now have a successful interMedia Text V8.1 installation.

INTERMEDIA TEXT INDEX를 사용하는 QUERY의 TUNING

제품 : ORACLE SERVER
작성날짜 : 2002-04-12
INTERMEDIA TEXT INDEX를 사용하는 QUERY의 TUNING
===============================================
Purpose
Intermedia text를 사용하는 query의 속도를 향상시킬 수 있는 방안을
알아보자.
Explanation
1. Make analyze all the table in the query
text index를 이용하는 Query 안의 모든 Table을 analyze 해 주십시요.
예를 들어 다음의 command를 이용할 수 있습니다.
ANALYZE TABLE <table_name> COMPUTE STATISTICS;
or
ANALYZE TABLE <table_name> ESTIMATE STATISTICS 1000 ROWS;
or
ANALYZE TABLE <table_name> ESTIMATE STATISTICS 50 PERCENT;
2. Using FIRST_ROWS hint
더 좋은 response time 을 위해서 first_rows hint 를 사용해 보십시요.
database에 기본적으로 설정된 optimizer mode는 choose mode입니다.
이것은 전체 처리시간(throughput)을 가장 빠르게 하기 위한(all_rows mode)
plan을 따르기 때문에 user의 입장에서는 first_rows 보다는 늦다고 느낄 수
있습니다.
Query에 다음과 같이 hint를 주고 performance를 확인해 보십시요.
select /*+ FIRST_ROWS */ pk, col from ctx_tab
where contains(txt_col, 'test', 1) > 0;
단, first_rows hint를 이용하는 경우 자동으로 score 순서대로
ordering 되지 않습니다. 왜냐하면 단어에 부합하는 문서를 찾는대로
즉시 결과로 나타내 주기 때문입니다.
3. Make sure text index is not fragmented
insert, delete 가 많이 되는 table의 경우 index fragment를 제거해 주어야
합니다. Index fragmentation 은 다음과 같이 확인할 수 있습니다.
select count(*) from dr$<indexname>$i; -> A
select count(*) from (select distinct(token_text) from dr$<indexname>$i); -> B
위의 결과가 A/B 의 값이 3:1 보다 크면 optimize_index 를 실행해 주시는
것이 좋습니다. 다음과 같은 command로 index optimization을 할 수 있습니다.
alter index <index_name> rebuild online
parameters('optimize full unlimited');
index rebuild중에 online option을 주면 rebuild하는 중에도 계속 index를
사용할 수 있게 됩니다. 하지만, 가능하면 사용자가 없을 때 rebuild하는 것이
좋습니다.
4. Check execution plan and sql trace.
기본적인 여러 가지 작업들에도 속도가 별로 향상되지 않는다면, 직접
sql trace를 떠서 Execution plan등을 확인해 보는 것이 필요합니다.
예를 들어 SQL*PLUS에서 다음과 같이 sql trace를 뜹니다.
alter session set timed_statistics=true;
alter session set sql_trace=true;
select ..... -> execute the query
실행 후,
exit
user_dump_dest 에 지정된 directory에 trace 가 떨어지면 다음과 같은
command로 tkprof 를 떠서 내용을 확인합니다.
$ tkprof <tracefilename> <outputfilename> explain=username/password

INTERMEDIA TEXT - INSO FILTER의 사용방법과 한글 설정

제품 : ORACLE SERVER
작성날짜 : 2003-02-05
INTERMEDIA TEXT - INSO FILTER의 사용방법과 한글 설정
====================================================
Purpose
Intermedia text에서 INSO filter를 사용할 때 한글을 설정하여 이용하는
방법을 알아보자.
Explanation
INSO Filter 에는 자체적인 속성이 없기 때문에, 한글 환경을 설정하기
위해서는 ‘ctxhx’에 적절한 입력 값을 제공하는 새로운 script 를 만
들어야 한다. 그 방법은 다음 두 과정을 거쳐야 한다.
첫번째, 새로운 shell script 작성 : ctxhx 에 원하는 매개 변수 설정
두번째, INSO_FILTER 대신 USER_FILTER 를 사용하여 작성한 script 를
command로 설정
다음은 INSO filter 를 이용하여 한글 문서를 검색하는 과정을 보여준다 .
데모 환경은 다음과 같다 .
* KOREAN_LEXER 사용
* Acrobab PDF, Word97, PPT97, Excel, Html 문서 검색
* 한글 검색을 위해 , INSO Filter 를 변형한 USER_FILTER 사용
1. 한글 검색 용 INSO Filter 생성
다음은 INSO Filter‘ctxhx’를 이용하여 한글 문서를 필터링하도록
'autofilt'의 내용이다. 이 파일은 실행 권한이 주어져야 한다.
$ cd $ORACLE_HOME/ctx/bin
$ vi autofilt
#!/bin/sh
$ORACLE_HOME/ctx/bin/ctxhx $1 $2 hangeul koreanhangul T
$ chmod 777 autofilt
* NT의 경우
메모장 등으로 oracle_home\ctx\bin directory에 autofilt.bat 라는
이름의 화일을 다음과 같이 생성한다.
oracle_home 이 E:\ora815 인 경우
set oracle_home=E:\ORA815
E:\ora815\ctx\bin\ctxhx.exe %1 %2 hangeul koreanhangul T
2. 테이블 생성
SQL> create table mydocs (
2 docid number primary key,
3 title varchar2(256),
4 fname varchar2(30),
5 document blob );
3. Pro*c 나 sql*loader등을 이용하여 long raw 또는 blob type에
file을 입력한다.
[예제] sql*loader를 이용한 방법
sql*loader를 이용하여 , ‘mydocs’ 테이블에 있는 BLOB 에 5개의 문서를
입력하기 위한 과정을 위해 쓰이는 file들은 다음과 같다.
* controlfile : mydocs.ctl
INFILE 'mydocs.dat'
FIELDS TERMINATED BY ";"
optionally enclosed by '"'
(docid, title, fname,
ext_fname filler char(40),
document lobfile(ext_fname)
terminated by eof )
* datafile : mydocs.dat

Intermedia text problem setup

Hi,
I've got a problem with creating a certain index. I have created a table an filled it with data:
create table ctxsys.quick
quick_id number
constraint quick_pk primary key,
text varchar(80)
I tried to create and index but I am getting the following "group of errors":
create index quick_text on ctxsys.quick ( text )
indextype is ctxsys.context;
ORA-29855: error occurred in the execution of ODCIINDEXCREATE routine
ORA-20000: interMedia Text error:
DRG-11422 linguistic initialization failed
DRG-00100: internal error, arguments : [52100],[drxs.c],[553],[gxtopen],[1]
DRG-11208: ORACLE_HOME is not set.
ORA-06512: at "CTXSYS.DRUE", line 126
ORA-06512: at "CTXSYS.TEXTINDEXMETHODS", line 78
ORA-06512: at line 1
I have also defined the enviromental variables:
LD_LIBRARY_PATH = C:\oracle\ora81\ctx\lib
and add to PATH = C:\oracle\ora81\ctx\lib
I am using win2k with oracle personal 8.1.7.
Any ideas what might have been setup wrongly?!
Thanks,
Kostas.

Well,
By using:
PARAMETERS ('NOPOPULATE')
was the only way so far, that I managed to create an indexer.
An indexer creation with different parameters would create the following errors:
ORA-29855: error occurred in the execution of ODCIINDEXCREATE routine
ORA-20000: interMedia Text error:
DRG-11422 linguistic initialization failed
DRG-00100: internal error, arguments : [52100],[drxs.c],[553],[gxtopen],[1]
DRG-11208: ORACLE_HOME is not set.
ORA-06512: at "CTXSYS.DRUE", line 126
ORA-06512: at "CTXSYS.TEXTINDEXMETHODS", line 78
ORA-06512: at line 1
Looking ways to overcome this problem...
Regards,
Kostas.

Intermedia text index creation error

My intermedia text was working fine, but now when create one index, it failed and it gave me the following error message:
ERROR at line 1:
ORA-29855: error occurred in the execution of ODCIINDEXCREATE routine

The listener itself is fine, is it because some library need to be re-created?

I've installed Intermedia text. During sample index creation i've get following error messages:

seems to be incorrect NET8 settings. How can I solve this problem?

Post Installation of interMedia Text

What scripts do you need to run if interMedia Text was installed after Portal was installed? The client now wants to use interMedia type searches.
Thanks.

Intermedia text is now Oracle text. Oracle text has it's own forum. The text people do not monitor this forum. Please ask your question in the Oracle Text Forum. You will get a quicker, more expert answer there.
Thanks,
Larry
