Training an SVM on table with schema flexibility fails

Dear colleagues,
I'm trying to train a Support Vector Machine on a table with schema flexibility.
On a small test table with only a couple of columns both the training and the prediction using the PAL libraries work fine. However, on my large sparse table with more than 1000 columns and "schema flexibility" set at creation time, I constantly run into the following error:
Could not execute 'CALL SYSTEM.AFL_WRAPPER_GENERATOR ('PAL_SV', 'AFLPAL', 'SVMTRAIN', PAL_SV_SIGNATURE)' in 30 ms 529 µs .
SAP DBTech JDBC: [423]: AFL error: [423] "SYSTEM"."AFL_WRAPPER_GENERATOR": line 32 col 1 (at pos 1346): [423] (range 3) AFL error exception: AFL error: registration finished with errors, see indexserver trace
The indexserver trace gives me something strange like:
AFLPM_SQLDriverObj.cpp(02439) : aflpm_creator : direction must be in or out
As far as I see it, all parameters are fine, though.
Is there a limitation that does not allow PAL functions to be executed on tables with schema flexibility? I suspect so, because I'm running into similar problems with the SUBSTITUTE_MISSING_VALUES function.
Thanks for any help,
Daniel

Hey there,
isn't there anyone who came across this issue? I'd love to know if this is a known technical limitation with tables that use the "schema flexibility" or rather a bug. In the former case, can anyone suggest a workaround?
I'd be grateful for any help or any pointer to further documentation.
Best,
Daniel

Adding a document to XMLTYPE table with schema

Hi all:
I am doing an example to create a table with a
registered schema associated (in Oracle9ir2), and i am
trying to insert a document that fits to schema into the
table.
The example is very simple:
I have the following schema:
<schema xmlns="http://www.w3.org/2001/XMLSchema">
<element name="items">
<complexType>
<sequence>
<element name="item" type="string" maxOccurs="unbounded"/>
</sequence>
</complexType>
</element>
</schema>
I succeed in registering the schema:
begin
DBMS_XMLSCHEMA.registerSchema(
'http://localhost/items.xsd',
getDocument('items.xsd'),
TRUE, TRUE, FALSE, FALSE
end;
I succeed in creating a table with this schema:
CREATE TABLE items of XMLType
XMLSCHEMA "http://localhost/items.xsd"
ELEMENT "items";
And i have the following document:
<?xml version="1.0"?>
<items xmlns:xsi="http://www.w3.org/2000/10/XMLSchema-instance"
xsi:noNamespaceSchemaLocation="http://localhost/items.xsd">
<item>Item1</item>
<item>Item2</item>
</items>
But when i try to insert it into the table with:
INSERT INTO items VALUES (XMLTYPE(getDocument('items1.xml')));
(getDocument is exactly the same as in XML Database
Developer's Guid[i]Long postings are being truncated to ~1 kB at this time.

truncated mail continuation...
(getDocument is exactly the same as in XML Database
Developer's Guide - Oracle XML DB Release 2 (9.2))
I get:
SQL> INSERT INTO items VALUES (XMLTYPE(getDocument('items1.xml')));
INSERT INTO items VALUES (XMLTYPE(getDocument('items1.xml')))
ERROR at line 1:
ORA-19007: Schema and element do not match
Do you know which is the problem?
I have proved changing the headers of the xml document
and schema in severals way, but it doesn't work.
Could be a problem with Oracle configuration?
Thanks in advance,
Mario Barcala

Problem naming table with schema prefix in Trigger

Hi,
When i try to compile the trigger having that body :
BEGIN
Insert into TechDb.DocumentTransfers(DocumentNumber, DocumentTypeID, StaffCodeFrom,
StaffCodeTo, TransferType, TransferDate)
values (:New.DocumentNumber, :New.DocumentTypeID, :New.StaffCode,
:New.StaffCode, :New.LastOperation, :New.DocumentDate);
END;
I get the following error :
Line # = 2 Column # = 4 Error Text = PLS-00201: identifier 'DOCUMENTTRANSFERS' must be declared
I noticed that the error disappears works if i don't need to prefix the DOCUMENTTRANFERS table with the schema name.
I am missing something ?
Thanks very much for your help.
Christian Moungou

Thanks John and Todd. It works exactly as you said.
But, does that mean i will have to directly grant the access right to all the users who will do the action which activates the trigger ?
Just to confirm : I assume that the user who executes the trigger is the user who does the action that activates the trigger ?

Insert performance on a table with schema based XMLType column

Hi,
We are inserting around 500K rows into a table which has one XMLType column (schema based). Schema is simple and the size of the XMLType column is also not very large (on an average only around 100 bytes (max might be around 1k-2k), but it takes around 1 hr for every 20K rows, which seems very slow.
The schema is like this :
<schema targetNamespace="http://www.citadon.com/xml/test.xsd"
xmlns="http://www.w3.org/2001/XMLSchema"
xmlns:xdb="http://xmlns.oracle.com/xdb"
xdb:storeVarrayAsTable="true"
version="1.0" elementFormDefault="qualified">
<element name="cas">
<complexType>
<sequence>
<element name="ca" minOccurs="0" maxOccurs="unbounded">
<complexType>
<sequence>
<element name="id" type="string"/>
<element name="value" type="string"/>
</sequence>
</complexType>
</element>
</sequence>
</complexType>
</element>
</schema>
Any thoughts on how to improve performance?

You need to have sufficient data.. Also the event show in the following code may help depending on the nature of the query....
Note in the PurchaseOrder Example if I only have 133 docs, instead of 10,000 I will get tablescan and index full scans

Migrating MySQL5 database to Oracle 10g - table with blob data fails

During data migration phase from MySQL5 to Oracle, noticed that the tables that have record length greater than 64K fails. It just says FINISHED for those tables without migrating any data. This is specially happening in the tables that have text and blob columns with data more than 20Meg in the blob fields.
Is this a bug? If not is ther any configuration file to increase the record size? Does it use SQL*Loader underneath to transfer the data or some other mechanism?

Thanks Spain, but using Offline scripts does not work for me as my record length is around 28MB and SQL*loader allows maximum record length of 20MB.
Is there any way to dump just the blob column data out of MySQL into a separate file?

Replication on the table with XMLType column and schema registered

Dear All,
Does Oracle XML DB 11g support replication for tables with schema registered?
Is there any recommended approach?
Thanks and regards,

Hmmmm ... I don't know if I should smile or frown with the implication that I am an OO guy :D :D
Most of my colleagues when I started working as a software engineer, treated me as too low-level because of my C background (started doing C in 1985).
In my last job, my colleagues hated my guts because I was asking them to squeeze every bit of performance out of C++ by using STL which is definitely not OO (although C++ is).
My current colleagues treat me as a DB guru (which I most definitely am not) and they overlook/forget the fact that most of them use Java libraries in their projects, that I wrote for them !
I am inclined to believe that I do not fall into any category in the end...
The only thing I am for sure - and I am proud of it - is inquisitive. I want to know everything there is about the tools I use, and so I end up spending hours and hours investigating... (Microsoft found that out the hard way when I filed 16 bug reports in 8 days when Visual C++ 6 came out ! Not that it hurt them though...)
This is where my confession ends (and my working on the XML validator starts...)

Hello Anybody, I have a question. Can any of you please suggest me how to make an xml file from the database table with all the rows? Note:- I am having the XSD Schema file and the resulted XML file should be in that XSD format only.

Hello Anybody, I have a question. Can any of you please suggest me how to make an xml file from the database table with all the records?
Note:- I am having the XSD Schema file and the resulted XML file should be in that XSD format only.

The Oracle documentation has a good overview of the options available
Generating XML Data from the Database
Without knowing your version, I just picked 11.2, so you made need to look for that chapter in the documentation for your version to find applicable information.
You can also find some information in XML DB FAQ

SSIS 2012 is intermittently failing with below "Invalid date format" while importing data from a source table into a Destination table with same exact schema.

We migrated Packages from SSIS 2008 to 2012. The Package is working fine in all the environments except in one of our environment.

But when we reorder the column in "Updated" in Destination table, the package is importing data successfully.
This looks like bug to me, Any suggestion?

Hi Mohideen,
Based on my research, the issue might be related to one of the following factors:
Memory pressure. Check there is a memory challenge when the issue occurs. In addition, if the package runs in 32-bit runtime on the specific server, use the 64-bit runtime instead.
A known issue with SQL Native Client. As a workaround, use .NET data provider instead of SNAC.
Hope this helps.

ORA-19007 when coping a table with an xml type in it to a new schema in the

ORA-19007 when coping a table with an xml type in it to a new schema in the same database.
Hi all,
When I copy a table with an xml type in it to a new schema in the same database I get an ora-19009.
The setup is as follows I have a schema a with table TABLE_WITH_XMLTYPE where data is:
CREATE

END;
when I try to do the following insert:
insert into schemaB.TABLE_WITH_XMLTYPE ( FOLDER_ID, SEARCH_PROPERTIES)
select FOLDER_ID, SEARCH_PROPERTIES from schemaB.TABLE_WITH_XMLTYPE;
I’ll get an ora-19007.
Can some one point me in the right direction how to solve this error.
Thanks Roelof.

Who did you create the second table, in other words, how did you COPY the table as you said...
If you created the second table via a CTAS (create table as select) then you will have created a table that is not the same as the original one. AFAIK I have once created an enhancement request for this after discovering that JDeveloper, for example, creates a "copy" via a CTAS which creates the wrong structure. Double check via package DBMS_METADATA.
SQL> set long 1000000
SQL> select DBMS_METADATA('TABLE','TABLE_WITH_XMLTYPE','SchemaA') from dual;
SQL> select DBMS_METADATA('TABLE','TABLE_WITH_XMLTYPE','SchemaB') from dual;If you have got two different tables, than Mark's solution should help.

ORA-00600 problem when create XMLType table with registerd schema

Hi,
I am using Oracle9i Enterprise Edition Release 9.2.0.4.0 on RedHat Linux 7.2
I found a problem when I create table with registered schema with follow content:

Does Oracle not support element reference to other element with dot?
For instance, body -> body.content
Thanks for your attention.

Sorry, amendment on the schema

How to share data in "User_*" tables with another schema

I would like to share the data in the USER_SEGMENTS table with another schema. If I create a view and grant select on the view, when the other schema queries the view the data is identical to themselves querying the SYS.user_segments table directly.
create view sys_user_segments as select * from sys.user_segments;
grant select on sys_user_segments to A;My guess is that the SYS.user_segments table is a view based on the current user.
Is there a way to share this data without creating a copy of the table?
Oracle: 10g
Thanks

Hi,
All the data dictionary "tables" whose names start with user_ (or all_ or dba_) are actually views, and what results they bring back depend on what schema you logged in to. I don't think there's any way to allow user A to directly see what's in user B's version of user_segments.
Why do you need this? Can you use the all_ views instead, by giving A some privileges on B's objects?
Failing that, you can replicate the data into a regular table. Inside a AUTHID DEFINER stored procedure, the data dictionary views (such as user_segments) are the versions of the procedure owner, so B can write a stored procedure (let's call it populate_my_segments) that populates a regular table (let's call it my_segements), and then grant EXECUTE privilges on populat_my_segments and SELECT privileges on my_segements to user A. A can then refresh the table and look at it whenever he wants to.
If A only needs to see a little information, e.g. the total number of bytes, from B's user_segments, then B can write a function just to return that information.

Indices and constraints on XML Tables/Columns (with Schema)

Hi,
I've read a lot of documents by know, but the more I read the more I got confused. So I hope you can help me.
Frist my Oracle Server Version: Oracle Database 11g Enterprise Edition Release 11.2.0.1.0 - 64bit
I've manages to create a table with a column with the type SYS.XMLTYPE and the storage modle "Object Relational" with an XML Schema.
I can insert data and I can execute XQuery statements.
I can also create an XMLTYPE table with my Schema, althoug the tool SQL Developer keeps telling me, that the one column wich is generated within the table is of the type CLOB instead of object realtional (which is what I defined).
The query for that is:
CREATE TABLE ENTRY_XML OF XMLTYPE
XMLTYPE STORE AS OBJECT RELATIONAL
XMLSCHEMA "BBMRI_Entry.xsd" ELEMENT "Entry";
That's where I am, now my questions:
1. What's the difference? I'm aware of the obviouse difference, that with the first way I can add relational columns as well, but apart from that? If I only want to store the xml data, is the second approach always better (especially in regard to my next question)?
2. My schema contains elements with attributes (which contain IDs), which have to be unique. So I tried to add a UNIQUE constraint, but failed. I found this (http://www.oracle.com/technology/sample_code/tech/java/codesnippet/xmldb/constraints/Specify_Constraints.html), but it just doesn't work.
Query: "ALTER TABLE ENTRY_XML CONSTRAINT ENTRY_XML_SUBID_UNQIUE UNIQUE (xmldata."SubId");"
Error: "ORA-01735: invalid ALTER TABLE option"
3. I didn't try yet, but I need to specifiy foreign keys within the XML as well (which is explained in the link at question 2). I guess the solution to question 2 will make this possible as well.
4. Since I can create a UNIQUE constaint for attributes (well, I can't yet, but I hope that this will change soon) I woundered if it would be possible to realize something like auto_increment. Although I see the problem with validating the xml input if the Ids are empty. Any suggestions on that problem? Do I have to query for the highest (free) id before I can insert the new documents?
Well, that's enough for today, I hope someone can help me!
Greetings, Florian

I've read through all the literature (again) and found out, that I did most of the stuff right in the first place. I just missinterpreted the generated tables for the types and wondered why they only contained one column. Well, at least one mistery solved.
But know to make it easier just one question, which might solve all problems I have:
How can I create UNIQUE constraints and FOREIGN KEYS when I have a table or column of the type XmlType with a schema using the object relational storage method?
I found a solution http://download.oracle.com/docs/cd/B19306_01/appdev.102/b14259/xdb05sto.htm#i1042421 (Example 5-12), but it just does not work for me.
I removed the FOREIGN KEY and tried it again and the UNIQUE Key works.
So basically the question is how to retrieve the "AId" Attribute. "XMLDATA"."AId", "XMLDATA"."Attribute"."AId" and "XMLDATA"."Subject"."Attribute"."AId" all do not work.
I've added my schema declarations at the bottom (which I've already successfully registred and used without foreign keys and constraints, so they work).
After I've registered the two schema files 3 types and 11 tables where created. One type for the attribute, one for the study type and one probably to link the attributes to the study types. The tables are one for the attribute, 4 for the content*-elements, 2 for the study type (I don't really know why two) and 4 with strange names starting with "SYS_NT" and then some random numbers and letters (looks alot like some base64 encoded string).
The Query I try to use to create the table is: (The table "Attribute" already exists and contains a field "ID", which is it's PK.)
CREATE TABLE STUDYTYPE_XML
OF XMLType (UNIQUE ("XMLDATA"."STId"),
FOREIGN KEY ("XMLDATA"."AId") REFERENCES ATTRIBUTE(ID))
XMLTYPE STORE AS OBJECT RELATIONAL
ELEMENT "StudyType.xsd#StudyType";
The error I get is:
Error starting at line 1 in command:
CREATE TABLE STUDYTYPE_XML
OF XMLType (UNIQUE ("XMLDATA"."STId"),
FOREIGN KEY ("XMLDATA"."AId") REFERENCES ATTRIBUTE(ID))
ELEMENT "StudyType.xsd#StudyType"

Dynamic Table with XML Schema

Hi, I am new to livecycle and wondering if there is any sample for setting up the dynamic table with XML schema so I can access the data through workbench's xpath. thanks.

Ivor,
Take a look at the samples shipped with Designer. For 8.2.1 release take a look at
C:\Program Files\Adobe\LiveCycle Designer ES\8.2\EN\Samples\Forms\Purchase Order\Schema\Schema\Purchase Order.xsd
and the form samples.
Otherwise, forward a request to [email protected] I would be happy to send you a sample XDP with a dynamic table and a schema.

Generating table with XML Type column while registering schema

Hi,
Is it possible to generate a table with an XML Type column during schema registering. Does the "xdb:defaultTable" always create an XMLType table?
Thanks.
