Oracle XML Indexing

Hi I have to index around 40 differnet property because my application is seraching on it.If create separate 40 column and index it then my indexing cost will be huge and maintaining 40 index will be i guess problematic.So Can anybody tell me if I want to store this different 40 propety in one XML doc and index XML doc then will oracle has in built feature to index XML.Any document or link or any suggestion will be highly appriciated.

I have to index around 40 differnet propertyBecause of this business need any way you will be facing indexing cost on dml operations, especially updates - http://download.oracle.com/docs/cd/B19306_01/server.102/b14211/data_acc.htm#i2678
will oracle has in built feature to index XMLOracle XML DB supports the creation of three kinds of index on XML content:
* Text-based indexes – These can be created on any XMLType table or column.
* Function-based indexes – These can be created on any XMLType table or column.
* B-Tree indexes – When the XMLType table or column is based on structured storage techniques, conventional B-Tree indexes can be created on underlying SQL types.

Also there may be some other ideas using XML and Oracle together - http://www.oracle.com/technology/tech/xml/index.html

If you have not specified an external WSDL file in your webservice where the arguments (with their types are defined) then you cannot use the type="any" in your webservice arguments.
If you want to use an external WSDL and define the argument types there you can do this by adding wsdlfile="nameOfExternal.wsdl" style="document" to your cfcomponent tag.

No, I don't think that explanation is correct. I don't think it has to do with user privs. besides, we don't
adjust rowids on an import -- we recreate the index, just like a b-tree index import would.
This should be working. It's most likely a bug in our (i.e. Text) import code -- SYS.XMLTYPE is a little
strange because under the covers it's actually a function-based index.
I will test it out and file a bug if I can reproduce the behavior on solaris.

Performance issues - which oracle xml technology to use?

Our company has spent some time researching different oracle xml technologies to obtain the fastest performence but also have the flexibily of a changing xml schemas across revs.
Not registering schemas gives the flexibity of quickly changing schemas between revs and simpler table structure, but hurts performance quite a bit compared to registering schemas.
Flat non xml tables seems the fastest but seeing that everything is going xml, this doesn;t seems like a choice.
Anyhow, let me know any input/experience anyone can offer.

Using Oracle Text in Oracle XML DB .

Hi all ,
The idea is simple ,i need to index all stored files in Oracle XML DB and the index should stay in Oracle DB . Using some 3 party index software is also possible but you need to write a mapping to move the index file in Oracle DB .
So i thought of using Oracle Text but i am not sure about how to retrieve such a document from Oracle XML DB , let me say over ftp or http ? . And if these documents are password protected -> how can Oracle Text allow this ?

For document display, there a bunch of potential solutions, you can look at [XML DB Repository|http://download.oracle.com/docs/cd/E11882_01/appdev.112/e10492/xdb03usg.htm#insertedID18], or the Text Application Developers Guide [Presenting Documents in Oracle Text|http://download.oracle.com/docs/cd/B28359_01/text.111/b28303/view.htm#i1006687] .
Password protected documents can't be indexed using the auto_filter.

Oracle.xml.xsql.XSQLServlet in Java Web Server 2.0

I have the alias *.xsql set to map to the servlet named oracle.xml.xsql.XSQLServlet under the Servlet Aliases section, but I'm not sure how to add the servlet under the Servlet section, as I'm guessing that this is the problem I'm now experiencing. I tried adding oracle.xml.xsql.XSQLServlet as both the servlet name and class, but this is not working.
Any help would be greatly appreciated. Thanks!

Rani,
The following is part of a message that was posted back on Nov. 7 of '99 from Steve Muench. I just followed this exactly with the Java Web Server 1.0.1 and it worked fine (including adding the classpath settings and xsql servlet mappings as it says below). Thanks,Dan
Here's the steps I just followed to run all the XSQL Demos under JSWDK 1.0.1
(1) Downloaded jswdk1_0_1-win.zip from Sun
(2) Installed in D:\jswdk-1.0.1
(3) Edited "startserver.bat" to add the
classpath entries needed by XSQL Servlet:
set CLASSPATH=%CLASSPATH%;d:\xsql\lib
set CLASSPATH=%CLASSPATH%;d:\xsql\lib\classes111.zip
set CLASSPATH=%CLASSPATH%;d:\xsql\lib\oraclexsql.jar
set CLASSPATH=%CLASSPATH%;d:\xsql\lib\oraclexmlsql.jar
set CLASSPATH=%CLASSPATH%;d:\xsql\lib\xmlparserv2.jar
(4)Edited d:/jswdk-1.0.1/webpages/WEB-INF/servlets.properties and added the line:
xsql.code=oracle.xml.xsql.XSQLServlet
(5) Edited d:/jswdk-1.0.1/webpages/WEB-INF/mappings.properties
and added the line:
.xsql=xsql
(6) Copied D:\xsql\demo to D:/jswdk-1.0.1/webpages/xsql/demo
(7) Started the Webserver with "startserver.bat"
(8) Browsed http://localhost:8080/xsql/demo/index.html
(9) Exercised all the demos.
Hope this helps.

Is Oracle XML DB...right solution?

Background:
I'm working on a system, which gets content from various providers and our engine processes the content and extracts the key information and stores them in relational tables. End users can view this information using our web application. Our web application supports multiple levels of filtering (in other words n levels of filters - described below). In addition, application also supports users to and, or, not one or more filters.
Problem:
With relational schema we were not able to support n number of filters.
Here's why it's difficult with relational schema:
- get base data set
- apply filter 1 (value 1, 2, 3)
- filter 1 results
- apply filter 2 (value 90, 91, 99) on filter 1 results (trick part is applying filter2 constraints on filter1 results)
- filter2 results
- apply filter n on filter n-1 results and so on.
not exact query.. sample version for demonstration (for simplicity sake i've used only one table...in reality each exists query will be using more than one table)
select *
from content f1
where filter in (1, 2, 3)
and exists (select null from content f2
 where f2.contentid = f1.contentid
 and f2.filter not in (90, 91, 99))
and so on...
As number of filters increases in number, it's difficult to generate efficient queries.
As interim solution, we have decided to store the entire data in memory and operate on it. It works very well (really fast too). But, we are limited by memory size. Above solution is not scalable for large volumes of data.
Solution (using Oracle XML db):
Then, I stumbled on to XML db option and I did some preliminary investigation. Seems like, nice solution for above problem.
This is what I did so far using XML db:
Step 1:
Created and registered schema.

Finally, Here are my questions:
1. Currently, I'm running my queries against 122k rows (data growth rate is ~2million rows per month) . I feel, it's taking too much time for such a small data set. How can i improve the performace of above queries? Or Is there a better way to write them? Since, its in evolution stage, i'm open to restructuring the schema if needed for better performance.
2. Is this correct approach? If not, Is there a better way to solve the above problem?
3. Any suggestions/tips are welcome.
I apologize, for such a lengthy post (my intention was to provide as much information as possible).
Thanks in advance.

Org Index Overflow makes it an index organized table (IOT) as distinct from a heap table (HT). In the original design we expected to see some performance enhancements from the use of IOT (In particular when re-serializing entire XML documents that had been persisted with Nested table storage), practice the benefits of IOT over HT in the XML DB use case have been marginal. We still create IOT by default when the tables are generated via Schema Registration, however it is likely that this will become controllable via a Schema Annotation in the not too distant future.
There are cases where the use of IOT causes problems, the most noticalbe of which is where you want to create a Text Index on a specific element or attribute which is mapped to a column in the Nested Table. If the NT is an IOT this is not possible, where if the Nested Table is an HT then there is no problem

Problem to create Explain Plan and use XML Indexes. Plz follow scenario..

Also
SELECT * from DBA_XML_TAB_COLS WHERE TABLE_NAME like 'TNAME1';Output is like:

- Can I change AnySchema to YES from NO for -column_name = XML_MESSAGE ? May be that will solve my problem.
- SYS_NC00025$ is the XML Index, Why don't I get any values for ANYSCHEMA, NONSCHEMA on it. Is this what is causing the problem.
Kindly suggest.. Thanks..

The problem sounds familiar. Please create a SR on http://support.oracle.com for this one.

Configuring Web Services for Oracle XML DB

Hi all...
I think I need some help one this subject....
We have a 10G Release 2 Oracle single instance ( not RAC) install on a Linux Redhat v5.3 64 bit server. Are developers are user Visual Studio .Net and wnat to send xml files to a web service so that the xml file (containing data) can call a PL/SQL package (to be written) which will take the data out of the xml input file and insert rows into a prefined table within the instance. Now they have browsed the web and have come upon the following links...
http://docs.oracle.com/cd/B28359_01/appdev.111/b28369/xdb_web_services.htm
http://docs.oracle.com/cd/B28359_01/appdev.111/b28369/xdb22pro.htm#i1026724
Currently, within the database I looked at the schema XDB and have unlocked the account and connected as the user XDB. There are some 680 objects in the following groups...
SQL> select object_type, count(*) from dba_objects where owner='XDB' group by object_type;
OBJECT_TYPE COUNT(*)
SEQUENCE 2
PROCEDURE 5
OPERATOR 8
LOB 334
LIBRARY 12
PACKAGE 20
PACKAGE BODY 17
XML SCHEMA 25
TYPE BODY 5
TRIGGER 12
TABLE 36
INDEX 51
FUNCTION 5
INDEXTYPE 2
VIEW 2
TYPE 144
16 rows selected.
Now in the links above it mentions that the xdbconfig.xml needs to be altered etc. However, I have searched the entire $ORACLE_HOME and there is no file definition of that description.
From a DBA prospective...what do I have to install on the Linux server? I assume from the Oracle Database 10g Companion Products I need to lay down Oracle HTTP Server in a new Oracle home as the first step...or not? Does the HTML DB need to be installed as well?
And for Configuring Web Services for Oracle XML DB...what else has to be installed? And from what product line?
Thanks in Advance....
Cheers
Roegr

Hi Marco...
First of all ...thanks for the reply.
I followed the link and the infor in that web page. However, there were a few things that did not work....
1. The http://localhost:8080/ as is brought up a web page withe the heading as
==========
ORACLE DATABASE 10g EXPRESS EDITION LICENSE AGREEMENT..
==========
The other browser test ftp://localhost:2100/
did not find any page?
2. Then I went onto running (as the sysdba) the pl/sql to enable the ORAWSV Entry Service
however it error out. So I did a describe on DBMS_XDB and the function deleteServlet does not appear
then I had a look and this link to > http://www.liberidu.com/blog/?p=471
was for 11G and the other link > http://docs.oracle.com/cd/B28359_01/appdev.111/b28369.pdf
was for 11G.
However, we are on 10G
=================
SQL> select * from V$version;
BANNER
Oracle Database 10g Enterprise Edition Release 10.2.0.3.0 - 64bi

NLSRTL Version 10.2.0.3.0 - Production
==================
So is there must be other sql for 10G?

Use JDBC to Access XML Documents in Oracle XML DB

Hi folks,
From the Oracle XML DB Developer's Guide 10g Release 1 (10.1) Chapter 12 Java API for XMLType, it show several examples for how java application use JDBC to access xml in XMLDB:
1. use getOPAQUE() on XMLTYPE table/column and then call XMLTYPE.createXML();
2. use getCLOBVal()/getStringVal()/getBLOBVal() in SQL statement;
3.use getObject on the result and cast directly to XMLType;
Among these 3 options, which is supposed to be the fastest way? Any difference between thin and oci?
I have run some tests about that and the result is the second option (with thin driver) is the fastest. It surprises me because I think oci should be faster than thin. Does the result make sense?
Thanks.

Have you tried to trace your sessions to see how much work is happening? Traces should give you quantifiable information on exact times and access paths to the data.
Below is a link to an O'Reilly book excerpt on Java programming with JDBC. Slightly data, but may be of assistance.

Recommend Oracle XML Book?

Can anyone recommend an good Oracle XML book. I've checked out "Oracle XML Applications" by O'Reily and have heard good things about it. But it's 3 1/2 years old and doesn't discuss Oracle 9i features and no mention of XML Schema (didn't exist at that point I guess).
Thanks for any advice!!!

Hi,
Some of the books which provide good information about Oracle and XML (with a small description) are present at the following links:
1.http://www.xml-book.com/xml-and-oracle-books.html
'Building Oracle XML Applications' by Steve Muench is a good one
Huge documentation is present free on OTN at the following link:
1. http://otn.oracle.com/docs/products/oracle9i/doc_library/release2/nav/docindex.htm#index-XML
Have a look at them. Various basic to advance samples are also present on OTN on XML at
1. http://otn.oracle.com/sample_code/tech/xml/xmldb/content.html
2. http://otn.oracle.com/sample_code/tech/xml/content.html
Check them.

Intermedia XML indexing

is it possible for intermedia to index XML such as:
<PERSON>
<NAME FIRST="STEVE" LAST="DONOVAN"/>
<HAIR COLOR="BROWN" LENGTH="SHORT"/>
<DOB AGE="31">2/7/1968</DOB>
</PERSON>
and then process a query such as:
Who has brown hair?
ie select name from person where hair.color = "BROWN"
Many thanks
null

Searches based upon structural conditions are not yet available
through interMedia text. Also attribute searches are not
supported at this time. For reference you should not put data
in attributes as that will not be compliant with XML Schema when
it becomes a recommendation.

NOTE: I think Oracle is a fantastic database and the XML implementation is lovely to use - also I know these are not limited to XE and also that some are fixed in 11g enterprise however I'm not sure if all are so I am posting here in the hope that Oracle will include fixes for all if any have been missed
1. getclobval() returns a spurious carriage return on end of the value returned
2. extract does not handle mixed content tags well (for example it simply discards tags that only have whitespace between them
3. XSL: using a xsl:number level="multiple" with anything beyond a simple count= xpath value crashes the database completely
4. XSL: insists on pretty printing output XML which is extremely odd behaviour and causes problems when dealing with mixed content

Another weakness I've seen is with the appendchildxml function and mixed content xml - it appears to likewise pretty print XML causing the injection of carriage returns and whitespace into mixed content nodes

Lost iCloud Pages Document because of xml index missing- finally resolved!

This morning I opened a Pages document in the cloud and started making changes to it the same as I have a hundred times in the past. The dreaded spinning ball appeared and I force quit Pages. Upon trying to open the same document I got the dreaded "xml index is missing". I callled tech support and was told by the first person that there is no way to recover the document. I also asked if Time Machine would have backed it up and he said NO, there is no way of recovering it if I didn't make a copy of it. I called Apple Support again and this time talked to a lady who at least tried to help me, but we weren't making any progress. I then found an article online (after searching earlier for the xml issue) that said Time Machine DOES backup Mobile Documents under the ~Library/Mobile Documents unless you specifically tell it not to. Luckily this person insisted that it backs up mobile documents because I was able to recover the document from a Time Machine backup. Thank you to the person who posted about the Time Machine backup! Now Apple needs to let their Tech Support people know about this!

Hank,
You were wise to search for answers here. There's no doubt that there is more collective wisdom in these discussions than you would expect to encounter in one first-echelon phone support person. You are also wise to be using TimeMachine so you have that recovery option available to you.
