All date tags are formatted YYYY-MM-DD.
All time tags are formatted HH:MM:SS. Note: SS can be set to 00 when not needed.
The event_link is the linking number that links several events together that are involved in the same
mission being performed at the same scheduled time. This can be anything as long as it is numeric.
It is recommended that and event_identifier from one of the events being linked together be used. To
be linked all events doing the same mission need this tag filled and it must be the same value for all
the linked events, including the one that may have the same event_identifier.
The status are the following: P-Pending, SA-Squadron Authorized, AA-AirOpds Authroized,
IP-InProgress, F-Finished, C-Cancelled, P-Postponed, D-Deleted, R-Rescheduled.
The status_code is a code that to provide further information about a given status. In particular it
should be used when a status of C, P, D, or R is used.
The airfield_location is a runway number or field location like grass, gravel, etc.

How to create index on a xmltype column stored as CLOB
actually i have two problems.

Creating Indexes within an XMLType column

I created following Indexes within the XML,
CREATE INDEX "OCA_DEV"."OCA_STATUS_CODE_INDEX" ON "OCA_DEV"."DOCUMENT_STATUS_XML" (EXTRACTVALUE('/ocaStatus/status/statusCode'));
CREATE INDEX "OCA_DEV"."OCA_STATUS_DATE_INDEX" ON "OCA_DEV"."DOCUMENT_STATUS_XML" (EXTRACTVALUE('/ocaStatus/status/statusDate'));
However the problem is that I will be having multiple status within each XML which violates the Indexing.
Is there any way I can still create the Indexes allowing multiple status values in each XML?
Thanks in advance.Hi,
You may want to store your document as a schema-based, object-relational XMLType to achieve that.
Then you'll be able to create indexes on the nested table used to store each "status" element.
Here's an example based on your sample document.
1) First, create and register a schema. The following is basic but sufficient here, let's call it "ocastatus.xsd" :
<?xml version="1.0"?>

DirectToXMLTypeMapping "create-tables" not generating XMLTYPE column type
Can someone tell me how to code an XMLTYPE field such that "create-tables" will generate the XMLTYPE column and such that the IntegrityChecker will not throw an error.
I am forced to run these alters after "create-tables" is run.
ALTER TABLE XML_SYS_MSG drop column message;
ALTER TABLE XML_SYS_MSG add (message XMLType);
Snippets:
<persistence...
<property name="eclipselink.ddl-generation" value="create-tables" />
</persistence>
public class XmlMessageCustomizer implements DescriptorCustomizer {
@Override
public void customize(final ClassDescriptor descriptor) throws Exception {
final DirectToXMLTypeMapping mapping = new DirectToXMLTypeMapping();
descriptor.removeMappingForAttributeName("message");
// name of the attribute
mapping.setAttributeName("message");
// IntegrityChecker requires uppercase for oracle
// name of the column
mapping.setFieldName("MESSAGE");
descriptor.addMapping(mapping);
@Entity(name = "XmlMessage")
@Table(name = "XML_MSG")
@Customizer(XmlMessageCustomizer.class)
public class XmlMessage {
@Id
@GeneratedValue(strategy = GenerationType.AUTO)
@Column(name = "ID")
private long id;
// @Column(columnDefinition = "XMLTYPE")
// private String message;
// ALTER TABLE XML_SYS_MSG drop column message;
// ALTER TABLE XML_SYS_MSG add (message XMLType);
private Document message;
public XmlMessage() {
public long getId() {
return id;
public void setId(final long id) {
this.id = id;
public Document getMessage() {
return message;
public void setMessage(final Document message) {
this.message = message;
Secondly if I turn on the IntegrityChecker it will fail
public class EnableIntegrityChecker implements SessionCustomizer {
@Override
public void customize(final Session session) throws Exception {
session.getIntegrityChecker().checkDatabase();
session.getIntegrityChecker().setShouldCatchExceptions(false);
}Adding:
mapping.getField().setColumnDefinition("XMLTYPE");to the customizer should solve the problem.

Disable Schema validation in XMLTYPE Column
Hi all!
I have created the following table with an Schema-based XMLTYPE column:
CREATE TABLE ADR1 (
idnr NUMBER,
FileType XMLTYPE,
constraint pk_idnr primary key (idnr))
XMLTYPE COLUMN FileType STORE AS CLOB
XMLSCHEMA "http://localhost:8080/home/usr/xsd/cc.xsd"
ELEMENT "File";
Now i want to disable the schema - validation for the XMLTYPE Column. I have done this before for an XMLTYPE Table. But in this case of an XMLTYPE Column i cant find the Constraint, that belongs to the Column.
Thanks for your help!

ORA-00904 on create table with xmltype column
Hi,
I am trying to create a table with syntax
CREATE TABLE ss_test(docid integer primary key, content varchar2(4000),acl XMLType)
XMLType column acl store as object relational
XMLSchema "acl.xsd" element "acl"
varray xmldata."ace" store as table ace_tab;
and getting ORA-00904.
acl.xsd is registered as

Couldnt figure out whats wrong with the syntax. Any pointers ?
Thanks,
RakeshHmmmm ... 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...)

ORA-01450 when trying to create index on xmltype column
Hi,
I have a table that contains an xmltype column. It is a schema-based column and uses object-relational structured storage. When I tried to create an index like:
create index ssual_sipuser_idx on ssua_line (extractValue(ssual_configuration, '/ssuaLineApplication/sipUser'));
I got the following:
ORA-01450: maximum key length (3118) exceeded
The sipUser tag is of string type. I have also tried creating the index on the extract function.
create index ssual_sipuser_idx on ssua_line (ssual_configuration.extract('/ssuaLineApplication/sipUser/text()').getStringVal())
Gave me the same error message. My database block size is 4k. This is Oracle 9.2.0.4 running on Solaris.
Any help will be appreciated.
Thanks,
GloriaThanks for the reply, Coby.
My field is really small, probably around 10 bytes. Actually I've been testing on two servers, a 9201 and a 9204. I know that Oracle doesn't support XML DB on 9201 anymore but our company hasn't switched over yet. Anyways, here's really what I saw:
9201
- creating an index with extractValue() or extract() doesn't work
9204
- extractValue() works
- extract() still doesn't work
Now I'm using the substr() workaround. I should also mention that extractValue() with a numeric field works (using getNumberVal()).
I wonder if specifying the field length in the XML Schema would make a difference. I may try that next. -
How to create index on XMLType column extension?
I have an XMLType column named "info" whose corresponding global element has a complexType "InfoType" in namespace "http://example.org/ord". The "InfoType" complexType is extended in two namespaces, "http://example.org/info/zipcode" and "http://example.org/info/street". How do I create a unique index using an "InfoType" element contributed from one of the extension namespaces?
I have included below a SQL script that completely describes the problem.
Thanks in advance for your assistance?

4) Creating the index :
SQL> create index CHANGE_HISTORY_IX1 on "SYS_NTr0U7dPWyRu6OVvDN2f5HEg==" ("CN");
Index created
If you're going to create multiple indexes like this, you could really benefit from renaming all the nested tables to meaningful names. That can be done via DBMS_XMLSTORAGE_MANAGE as well. -
How to create index on xmltype column
I have a table having only one column xmlcontent (xmltype). This table stores xml data of about 10GB size. I'm using extract value to move the data to staging tables.
How can I create index on xmltype column?
Create index indexname on table (column) doesn't seem to work.
Sample xmlstructure is given below
<Root>
<Type>Insert</Type>
<Date>2006-12-29</Date>
<Source>8</Source>
<id>data</id>
<key_flds>
<fld><id>Key1</id><val>C</val></fld>
<fld><id>Key2</id><val>429672</val></fld>
<fld><id>Key3</id><val>8</val></fld>
</key_flds>
</Root>
I need to do extract value on all tags and move them to corresponding relational tables.Hi, you need to create them using something like this (what I have used and work rather well - if I did not load the xml into an xml table, the processing took about 10 minutes, while the indexed xml table took just a few seconds). statute_xml is the table name and sxmldoc is the xml column/field.
create index desc_idx on statute_xml
(sxmldoc.existsNode('/SimpleTypeCompanion/EnumerationValue/@description'))
create index sid_idx on statute_xml
(sxmldoc.existsNode
('/SimpleTypeCompanion/EnumerationValue/Text')
create index effdate_idx on statute_xml
(sxmldoc.existsNode
('/SimpleTypeCompanion/EnumerationValue/@effectiveDate')
Hope this helps.

XMLType column based on XML Schema: several questions
Hi,
I've a table on an oracle db version 10.1.0.4 where I stage the xml files containing orders created on a third party's system using BizTalk.
Although the storage I opted for is based on an XML Schema, defined by this third-party, I am facing big perfomance issues with files bigger than a few hundreds of kBs.
For instance, a 32Mb file takes more than 2 hours to be processed.
Now, after reading other threads in this forum and the documentation, my understanding of the problem is that the whole issue is with the correct indexing of the nested tables.
Here is my current XML Schema definition:

When I registered the XMLSchema, the following types and tables were automatically created and you can see the hierarchy below:
(by the way, I could not find any xdb_utilities.printNestedTables mentioned elsewhere)
XML_ORDERS
|_PickData381_T
|___ProdRun382_T
|_____PickWave388_COLL
|_______PickWave383_T
|_________Customer387_COLL
|___________Customer384_T
|_____________InvOrder386_COLL
These objects are then used in the following nested tables:
TABLE_NAME TABLE_TYPE_NAME PARENT_TABLE_NAME PARENT_TABLE_COLUMN
SYS_NTaK/5zar5S0WitSsgu6OKPQ== PickWave388_COLL PickData389_TAB "XMLDATA"."ProdRun"."PickWave"
SYS_NTf6QvwVm8SFKz+K/YYWq+WQ== Item408_COLL ProdData409_TAB "XMLDATA"."Item"
SYS_NTtu05ilrRQqmuEN4k+07VDA== Customer402_COLL OutboundParty403_TAB "XMLDATA"."Customer"
SYS_NTK6fhWq5uTJ+vKcgBpNm1Fg== InvOrder386_COLL SYS_NTIIzv7bkXQSSS43igtfi5eg== InvOrder

Note that I cancelled this operation before it was over so I imagine that these figures refer to the statistics as of the time when the operation was interrupted.
So, here are finally my questions.
In order to create the constraints on the nested tables as shown in other threads, do I need to drop the existing xml_orders table and ancillary object types and recreate them or is there a way to add such constraints using the existing system generated object names?
Secondly, the xml_orders table may contain severale documents, not just one and his current primary key is the column ID. So, in order to uniquely identify the deepest element in the xml document, I need first to select the relevant document by means of the id column.
Would it be better to create the indexes containing this id column together with the nested_table_id and array_index?
Thanks for you help.

PS: I wrote a 10 lines xsl transformation that I passed on to Saxon together with the 32Mb file. It took less than 1 minute to produce a flat file that was loaded almost instantly by SQL*Loader. So, what I am looking for is a procedure loading this stuff in less than 2 minutes or possibly less.Does the following help

Range partitioning on virtual column based on binary xmltype column
Alright, our DBA finally got around to upgrading to 11.2.0.2. Now I'm running into another issue:

PARTITION BY RANGE (ts)
PARTITION d_p2012_07 VALUES LESS THAN (TO_DATE('1-8-2012','DD-MM-YYYY')),
PARTITION d_px VALUES LESS THAN (MAXVALUE)
);On our old 11.2.0.1 install this command works fine (tho due to other issues 11.2.0.1 doesn't work for our search queries)
On our 11.2.0.2 install, I get the following error:

Error report:

*Cause: Partitioning column specified by the user was an object datatype
(object, REF, nested table, array) which is illegal.
*Action: Ensure that no partitioning column is an object datatype.Anyone know what's up with that? What changed between the 2 DB versions that could cause this to fail?Alright, seems that's just a display issue then.
Looking in user_lobs like suggested above gives

I'd like to use the suggested xmlcast/xmlquery solution, however it doesn't seem to play well with our custom timestamp format.

Import is very Slow with xmltype column in oracle 9.2.0.7
Hi
We are using oracle 9.2.0.7 on Solaris
The import without XMLTYPE column is faster the import of the table with XMLTYPE column.Also when we do the export in direct path it is still going for Conventional(I suppose this is correct for XMLTYPE).
Is this the general behaviour of XMLTYPE...if so how to improve the performance of the import.
Can anybody help us out in resolving the issue.here is the output

Problems sorting larger sets of XMLType columns/tables
Hi,
Here's something I tried to wrap my head around:
I'm using Oracle 11g r1 for Windows Server 2003.
I've imported a fairly large set of XML files into a temporary XMLType table. Now
I want to sort the contents of the table and put them into another table which
uses a sequence to get primary keys (would be a longer story to explain, basically
sorting by this non-XML primary key is super-fast as opposed to everything else
I've tried, plus I need something unique):
INSERT INTO realtable SELECT 0, object_value
FROM tmptable ORDER BY extractValue(object_value, '/some/*/field');It works fine for a very small number of rows but when I tried with about 30000 rows,
still not too much, two kinds of things can happen. Either, Oracle gobbles up a huge amount
of memory (>1,5GB) until the statement breaks:
ORA-04030: Zu wenig Prozessspeicher fⁿr Versuch 33292 Bytes zuzuweisen
(callheap,kllcqgf:kllsltba)Or I get something like this:
ORA-00600: Interner Fehlercode, Argumente: [kqludp2], [0x1F31EC94], [0], [], [], [], [], []I haven't wasted too much time looking into this. I tried storage options clob and binary xml
for tmptable. Clob seems to induce the latter problem and binary xml the former but I haven't
made further experiments.
I can create a workaround from outside Oracle I think, so it's not serious however I'd would
be interesting to know what happened or if there is a better way to do this.
Thanks!Unfortunately, the problems are not reproducible in a meaningful way. All I can say is that once a statement will result in a kqludp2, it will always fail with the exactly same error message until I reinstall the database from scratch. On the other
side, when I found a configuration that works, I could delete and rebuild/refill a table multiple times without the thing ever breaking.
As the most recent example, after the latest trouble I deleted the database and changed my DDL scripts to the last configuration I wanted to try and broke the last time (several tables with two normal columns and an XMLType column each), everything worked like a breeze.
I can file a TAR when I get a support ID from my employer, however I installed the database on a virtual machine (I should have mentioned that earlier) and Oracle doesn't officially support that configuration from what I know so I'll doubt they'll do anything about it. I've procured a physical computer now and try to reproduce any of the problems when I get to it. -
Help creating a form on xmltype

I would like to create a form on an xmltype column and be able to update the tags.
I have a view with the tags extracted from a clob column.
