Oracle 8i - XML Storage

Hi
For my project, I am thinking of saving XML files in the CLOBS
columns in the database. I was wondering if there is any limit
for using the number of CLOBS in the database. Also, I am not
sure of the maximum capacity a CLOB can store. I need help on
both the above concerns.
Also, I want to know some method to about developing the
system. Is there a tool available for storing XML docs in CLOB
cloumn? If not, How should I go about developing one?
What will be the best way to extract contents and show them on-
line in HTML format?
I would appreciate any kind of help from someone developing
similar application. A small example would be great.
Hoping to get some quick help...
Premal.

I am not sure to which features you refer? If you are asking
about the CONTAINS operator that works in 8i now. The document
registration to a schema will be delivered in the iFS beta.

Clob vs. Blob XML Storage

Hi, we're currently using Oracle 8i to store XMl and are wondering which to use for large XML pieces CLOB or BLOB. Although I saw an earlier post differentiating CLOBS from BLOBS. Which is better for XML storage. I noted that Oracle always seems to favor Blob fields. Does Clob flatten character formatting such as umlauts, etc.? Any help would be greatly appreciated.
- A. N.

I have been using a CLOB column for some time now and have found no differences. The Indexing that Intermedia Text offers is super fast as well.

Xml storage

we can storage xml into oracle correctly if we had alreadly created the tables in it,but if we have not,how can we do it.Can the tables be automaticly created,if the xml have more than one lever.
if anyone know something about that ,please tell me.

In case you may choose DBMS for your project, i'd prefer another stategy and attact your attention to co-called ""post-relational"
DBMS. In comparison to Oracle, which XML support and services are built around old relational core (forex XMLtype in reality is nothing more than usial CLOB type), post-relational databases offer direct storage and work with XML.

I'm using 11g TP4 on Windows Vista Home Premium. This is my first time crying out for help in any forum (after 19 years of development) so I'm really desparate for help. I'm new to JAVA development and JDeveloper; hence a lot of this stuff is greek to me.
I did post in the JDeveloper forum and John Stegeman re-directed me to the "JDeveloper and OC4J 11g Technology Preview" forum.
I was leaning more toward an operating system issue since 11g TP4 works just fine on my Windows XP SP2 desktop. It is just so slow on it (504 MB of RAM) that I decided to run it on my laptop (3062 MB of Ram) where the performance is awesome, but I can't test a damn thing since I can't get the embedded server to work/start. Just hoping others have solved this issue and can pass that knowledge on to others.

XML storage and retrieval in/out of 8i

Please take into consideration my lack of exerience in XML and
Oracle8i when you read this question....
Our project is considering using Oracle8i to store, query &
retrieve XML documents. Having read several Oracle web sites on
XML, I'm left with the impression that the Oracle iFS is at the
conerstone of Oracle's XML implementation. The idea of a
drag-n-drop approach to place XML data files into the database is
interesting, but I suspect our project needs a more "programatic"
(i.e. background/automatic) approach to conveniently storing and
retrieving XML data. I've read only "hints" that O8i will support
this. My question: where can I find out more about what Oracle8i
has to offer the developer in this area?
Thanks

Multiple DataControls - oracle.bali.xml.model.XmlInvalidOnCommitException

I have an ADF BC/Faces application with 2 model projects, each having their own app module so I can connect to 2 different schemas for different pages. I am seeing multiple data controls appear in the DC palette - why? In DataBindings.cpx there are only 2 data controls.
For example, I just added a new view to one AM. It appeared in the DC palette under a new DataControl (AppModuleDataControl3) instead of in the existing DataControl for that AM. When I dragged from the view to the page, I got "could not complete findOrCreateDataControlInApplication because it would result in an invalid document." The full error is below.
The only unusual thing I can think of is that I am using AM configurations with JDBC DataSource for the connection type. My Jdev version is 10.1.3.3.

This issue was caused by an import of a reusable library of business components which contained app modules. In the application where I maintain the BC library, I created app modules so I could verify the model before using it in other applications.
From looking at the .jpx files for my models it appears that these app modules
were imported as part of the library. So I removed the app modules and corrected my .jpx files.
I'd suggest a note be added to the section about reusable BC libraries to make sure that any test app modules are excluded when jar files are generated.

Oracle hardware and storage solution configuration questions

Hi all,
I am configuring hardware and the storage solution for a project and am hoping to have some questions answered about using Oracle as the storage solution.
The current setup will have 2 Dell NX3100 NAS gateways each with dual quad core processors, 24GB of RAM, 12x2TB data disks, and running Windows Storage Server 2008 64bit as the OS.
Will also have direct attached storage of 2 Dell PowerVault MD1200 disk arrays, each disk array with 12 x 2Terabyte SAS disk drives giving a total of 36TB of storage space for each NAS Gateway.
Based on this information, is there any problem with two Oracle Standard Edition installation (1 per NAS) holding up to 36TB of data (mostly high res images) in this hardware configuration?
Does Oracle have a built in solution for replicating data between the 2 NAS heads and down to the disk arrays? Where the application sever will write to one of the NAS+disk arrays and then that data is written from the first NAS to the 2nd NAS+disk array? Currently I've used DoubleTake in other projects but am wondering if Oracle has something similar that is built in.
Finally, will Backup Exec Oracle agent work with this configuration for backing up the data to a Dell PowerVault ML6020 Tape backup device?
Thanks in advance for any insight.

Oracle's XML Publisher in JDeveloper and XSQL Servlet

A While ago, in this thread JDeveloper 10g, XSQL and FOP , was mentioned an ongoing effort for the "integration of Oracle's XML Publisher in JDeveloper and XSQL Servlet", Is this still happening ?, will this be something will be able to use without having to be an Oracle Apps shop? Any additional info would be appreciated.

Hi,
is there any progress about XML publisher integration with JDeveloper. I'm right now examining XML publisher but there is no explicit directions and explanations of using XML publisher with jdeveloper.
any news !?

How to tune the performance of Oracle SQL/XML query?

Hi all,
I am running Oracle 9i and like to run the following Oracle SQL/XML query. It takes about 3+ hour and still not finish. If I get rid all the XML stuffs it only take minutes to run. Does anybody know how to what's the reason of this slow and how to tune it?
SELECT XMLElement("CUSTOMER",
XMLForest(C_CUSTKEY "C_CUSTKEY", C_NAME "C_NAME", C_ADDRESS "C_ADDRESS", C_PHONE "C_PHONE", C_MKTSEGMENT "C_MKTSEGMENT", C_COMMENT "C_COMMENT"),
(SELECT XMLAgg(XMLElement("ORDERS",
XMLForest(O_ORDERKEY "O_ORDERKEY", O_CUSTKEY "O_CUSTKEY", O_ORDERSTATUS "O_ORDERSTATUS", O_ORDERPRIORITY "O_ORDERPRIORITY", O_CLERK "O_CLERK", O_COMMENT "O_COMMENT"),
(SELECT XMLAgg(XMLElement("LINEITEM",
XMLForest(L_ORDERKEY "L_ORDERKEY", L_RETURNFLAG "L_RETURNFLAG", L_LINESTATUS "L_LINESTATUS", L_SHIPINSTRUCT "L_SHIPINSTRUCT", L_SHIPMODE "L_SHIPMODE", L_COMMENT "L_COMMENT")
FROM LINEITEM
WHERE LINEITEM.L_ORDERKEY = ORDERS.O_ORDERKEY)
FROM ORDERS
WHERE ORDERS.O_CUSTKEY = CUSTOMER.C_CUSTKEY)
FROM CUSTOMER ;
Thanks very much in advance for your time,

Why not something more like

FULL OUTER JOIN fact1 d
ON l.company = d.company
AND l.transactiontypeid = 1
AND d.transactiontypeid = 2;
Because this is not an equivalent of the original query.
drop table t1 cascade constraints purge;
drop table t2 cascade constraints purge;
create table t1 as select rownum t1_id from dual connect by level <= 5;
create table t2 as select rownum+2 t2_id from dual connect by level <= 5;
select * from (select * from t1 where t1_id > 2) t1 full outer join t2 on (t1_id = t2_id);
select * from t1 full outer join t2 on (t1_id = t2_id and t1_id > 2);
     T1_ID      T2_ID

Oracle and XML-DATA

Hello,
I have read the Oracle XML SQL Utility documentation and also
the answer of Oracle team to Johnson Scott and as far as I
understand, the XML that is produced from the database and
loaded in it must verify a given DTD syntax.
Is this DTD available somewhere ?
What I have understood about XML Data of w3c is that it gives a
way to describe the content of a database.
What is Oracle position on that subject ?
I do ask this question because we have at present an SGML file,
with its own DTD that contains data we have to
insert/delete/update in an Oracle Database.
We are thinking of converting this SGML file in an XML file,
with tools like OMNIMARK or BALISE, that could be easily
integrated in the Oracle Database.
We are looking for the best solution to our problem and think
that Oracle tools like Oracle XML SQL, parserand Class generator
could be really usefull.
What do you think of this problem and of the solution we imagine
Thanks for your help,
Best regards,
C line.

Hello,
I am actually studying the tools that Oracle offers to treat XML
data.
When reading the description of your products I can see two
solutions to my problem.
I remind it to you :
I have an SGML file with its own DTD that contains data we have
to insert/delete/update in an Oracle Database.
I can imagine two solutions :
1- one with Oracle IFs XML support :
To use this one I have to convert my SGML DTD in an XML one
(they should be very similar) and then write a program that
would convert my SGML file in an XML one.
Then create an Oracle iFS document descriptor that indicates how
each part of my file should be stored in my Oracle database.
2- an other one with Oracle XML SQL utility :
To use this one I have to convert my SGML file in an XML file
that is well-formed (i.e. that Oracle XMLSQL utility can
understand).
This convertion is much more difficult to do than the one I have
described above.
Are those two solutions correct ?
If yes, which one is the best in your opinion ?
Could you use XML Data with Oracle XML SQL utility ?
Is the DTD you have defined for this tool compiliant with XML
Data ?
If not why ?
I have not the tool from which I can get it but I would be
interested by the description of this DTD which is the best way
to see what I can do with this tool (and imagine a solution for
update if it cannot be easily done).
I would also be very interested in having the description of DTD
for Oracle iFS document descriptor files (as far I have
understood they are XML files) or an example of quite a complex
one so that I can I an idea of how it cold fit to my problem.
I have been really impressed by Oracle team very fast answer and
thank you very much for your help.
Regards,
C line.

URGENT! SEGV-errors when using Oracle C XML Parser for Solaris

I often (not always) got SEGV-error with core dump when I use Oracle Oracle C XML Parser for Solaris. This Error is always got in the call of the the function xmlinit(...) with all params as NULL but the first required for the error code and the second which i assign a macro that evaluates to "US-ASCII". Does anyone knows about this problem?
I am using a very short, wellformed and validated XML document.
I would be very glad for some help about this!

Please provide a sample program along with the version number of the XML parser.
