Deleting a Schema

Hi,
How can i to delete a schema by Apex System Administrator?
I made an application, but now I want to delete everything.
Thanks,
Marcelo

Why the whole workspace? You can drop the tables and associated database objects and delete the application through either APEX's development environment or through SQL developer..
Thank you,

How to delete a schema?

Is there anyway to delete a schema (in the meta data) for the project view as opposed to just turning it off?

Yes it appears to,
Though I'm curious how this will work across different computers. I usually create a custom Column display for my music editing. Simple enough really. Usually the show and what act I've used a music cue in. So I know not to repeat a cue for at least one act. If i pass a project on to a different editor on a different machine, will it automatically create that schema? or just the columns that have data entered into them? Not sure, I'll have to experiment and see.
Thanks again.

Error deleting registered schema

Hello all,
I have registered a Schema in oracle through PL/SQL with the following script created by Console Management Client:
DECLARE
xclob CLOB;
BEGIN
dbms_lob.createtemporary(xclob, FALSE,dbms_lob.SESSION);
? := xclob;
end;
BEGIN
DBMS_XMLSCHEMA.REGISTERSCHEMA(schemaurl=>'http://www.gimo-armada.es/ICR/ICR.xsd', schemadoc=>:XMLSchemaTextCLobPtr, local=>FALSE, gentypes=>TRUE, genbean=>FALSE, gentables=>TRUE, force=>FALSE, owner=>'DAVID');
DBMS_LOB.FREETEMPORARY(:XMLSchemaTextCLobPtr1);
END;
The schema is registered without problems and the file ICR.xsd can be found in /sys/schemas/PUBLIC/www.gimo-armada.es/ICR
Now, I try to delete this schema with the script:
DECLARE
Res BOOLEAN;
BEGIN
Res := dbms_xmlschema.deleteSchema('http://www.gimo-armada.es/ICR', dbms_xmlschema.DELETE_CASCADE_FORCE);
END;
But the system returns an error:
PLS-00222: no function with name 'string' exists in this scope
I do not understand where is the problem, because the function are in the same package.
The current user has been defined as SYSDBA.
Thanks in advanced,
David.

I think you are still a little confused between namespace and schemaURL or SchemaLocationHint...
<?xml version="1.0" encoding="WINDOWS-1252"?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema"
xmlns:xdb="http://xmlns.oracle.com/xdb"
xmlns:icr="http://www.gimo-armada.es/ORSWE/ICRI"
targetNamespace="http://www.gimo-armada.es/ORSWE/ICRI"
elementFormDefault="qualified" attributeFormDefault="unqualified">So the target Namespace for your XML Schema is 'http://www.gimo-armada.es/ORSWE/ICRI'
I have uploaded the XSD to the folder /ORSWE/Esquemas/ICRI through WebDAV.
I have registered the new XSD with the following script:
begin
dbms_xmlschema.registerSchema(schemaurl=>'http://www.gimo-armada.es/ORSWE/ICRI', schemadoc=>xdburitype('/ORSWE/Esquemas/ICRI/ICR.xsd').getXML(), local=>FALSE, gentypes=>TRUE, genbean=>FALSE, gentables=>TRUE, force=>FALSE, owner=>'DAVID');
end;
/This means that you have also used the value of the namespace as the SchemaLocationHint. This is allowed, but probably not what you intended. Remember to XDB the SchemaLocation hint becomes a key which is can use to look for the XML Schema internally. It is never used as a URL to actally do and look for the schema externally.
I would have exected the schemaLocationHint or SchemaURL to be the logical location of the XML Schema, not the namespace or the actual location of the XML Schema in the XDB repository. The one advantage of using the actual location in the XML DB repository iss that it allows 3rd party tools like XMLSPY to locate the XML schema.
Eg
begin
dbms_xmlschema.registerSchema(schemaurl=>'http://www.gimo-armada.es/ORSWE/xsd/ICRI/ICR.xsd', schemadoc=>xdburitype('/ORSWE/Esquemas/ICRI/ICR.xsd').getXML(), local=>FALSE, gentypes=>TRUE, genbean=>FALSE, gentables=>TRUE, force=>FALSE, owner=>'DAVID');
end;
/At this point the value of the schemaLocation tag is a tuple consisting of the targetNamespace and the SchemaLocationHint
eg
<ICR xmlns="http://www.gimo-armada.es/ORSWE/ICRI"
xmlns:xdb="http://xmlns.oracle.com/xdb"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.gimo-armada.es/ORSWE/ICRI
http://www.gimo-armada.es/ORSWE/xsd/ICRI/ICR.xsd">hope this helps..

Hi,
It seems you're trying to delete something that's not there... Or the script can not found it for some reason - permissions?

Invalid objects and ORA-00600 after deleting XML schema

I am running Oracle 10.2.0.3 on Solaris 10. I am new to XML DB but my developers requested it for a new application. Recently we have noticed the following issue:
My developers have attempted to re-register several schemas using:
DBMS_XMLSchema.deleteSchema(SchemaURL => l_strSchemaURL,
Delete_Option => DBMS_XMLSchema.Delete_Cascade_Force);
And then re-register.
DBMS_XMLSchema.RegisterURI( SchemaURL => l_strSchemaURL,
SchemaDocURI => l_strImportURL,
Local => True,
GenTypes => True,
GenBean => False,
GenTables => True,
Force => False,
EnableHierarchy => DBMS_XMLSCHEMA.ENABLE_HIERARCHY_RESMETADATA);
Afterwards I have noticed several invalid objects:

I opened a TAR with oracle but they have not made much headway. Are we attempting to de-register the schemas improperly? Has anyone seen this issue before?
Thanks,
Brian

SR 6204906.993. Up to this point oracle was able to help me identify that the invalid objects were related to the ORA-00600 but it was just recently that it appeared the Issue was possibly related to the delete schema procedure. The informed me that they were not aware of any known issues with this procedure.
Thanks

Generate script to delete all schemas

Hello All,
I'm going to do a reimport and i want to delete all the schemas in the db....
I've written this script:
select 'DROP TABLE schemaname.' || TABLE_NAME || ' CASCADE CONSTRAINTS;'
from dba_tables
where owner = 'schemaname'
order by TABLE_NAME;
how can i generate the script for all the schemas? The above will only list one schema...
Basically i want to do another import and get a clean log (as clean as possible).
Thanks.

You modify your query to select a distinct list of object owners. In fact you might want to look for some other objects besides tables. If you are only interested in tables you should probably change the subquery to look at dba_tables.
select 'DROP TABLE '||owner||'.' || TABLE_NAME || ' CASCADE CONSTRAINTS;'
from dba_tables
where owner in (select distinct owner from dba_objects
where owner not in ('SYS','SYSTEM','OUTLN','PUBLIC')
order by TABLE_NAME;
You should look the list of owners over very carefully before running the resulting DDL commands. There are other owners, depending on your Oracle version and features in use, that you will not want to touch.

Delete and schema statistics

Hi,
every week i will compute statistics with dbms_stats.gather_table_stats.
First :
May i delete statics before compute them again ?
Second :
Is it beter to compute statistics on all schema against on each table ?
Thanks.

Is it beter to compute statistics on all schema against on each table ?Well, if you have big tables, compute statistics, which is estimate_percent=>100% would take good amount of time.
Estimate_percent=10 would be an ideal one on most of the databases. However, you need to test queries with the estimate_percent size.

Error when deleting schema

Hi,
When I perform a 'select * from dba_xml_schemas' I see something like this:
OWNER SCHEMA_URL LOC SCHEMA INT_OBJNAME ...
TEST http://xmlns.europe.bd.com/broadvision/editorial.xsd NO XMLTYPE() ...
XDB http://xmlns.oracle.com/xdb/XDBSchema.xsd NO XMLTYPE() XDbD/PLZ01TcHgNAgAIIegtw== ...
Notice that the INT_OBJNAME is empty for the 'http://xmlns.europe.bd.com/broadvision/editorial.xsd' schema.
When I try to delete this schema, I get the following error:
SQL> exec DBMS_XMLSCHEMA.deleteSchema('http://xmlns.europe.bd.com/broadvision/editorial.xsd');
BEGIN DBMS_XMLSCHEMA.deleteSchema('http://xmlns.europe.bd.com/broadvision/editorial.xsd'); END;
ERROR at line 1:
ORA-31000: Resource 'http://xmlns.europe.bd.com/broadvision/editorial.xsd' is not an XDB schema document
ORA-06512: at "XDB.DBMS_XMLSCHEMA_INT", line 0
ORA-06512: at "XDB.DBMS_XMLSCHEMA", line 80
ORA-06512: at line 1
What am I doing wrong here? I also tried to delete the schema with Enterprise manager, but I get the same error there also...
Anybody any idea?
Kristof

Was the user you were using to delete the schema the same one as the one who created the schema ?.
Was the schema registered globally or locally ?
Were any other SQL sessions or FTP / WebDAV sessions active that were using the schema ?
Deleting from the XDB$ table is not generally a good idea. I would strongly recommend against this process.

This happened to me when I manually deleted objects generated during the schema registration.
I have now a couple of schemas registered in the database that I cannot delete anymore.

Deleting a Deployed Categorization Schema

*Hello,*
*I was wonder if anyone knows how to delete a categorization schema with deployed status? After playing in the IC web client it only appears draft categorization schema's can be deleted.*
*Is there a way to delete deployed schema's in back end? Such as a t code that allows the deletion of master data?*
*Any assistance would be appreciated.*
*Thanks*

Hi.
You have to create a new version of your categorization schema, and for this new version you release it under a smaller limit of time, for instance valid to (1 minut ahead current time).

Connect role allows user to update/delete row of a table of another schema

I am using oracle 9i r2, I created a user and only give him CONNECT role. Then I opened the sqlplus and found that he could query table of another schema which doesn't belong to the new user, but the thing which scares me most is that when I tried to update/delete a row from a table of another schema, it succeeded. Also, I created a new role with system priviledges CREATE_SESSION and SELECT_ANY_TABLE then granted to new user and revoked the CONNECT role but the same thing happened like before. What I am doing wrong? By the way, I am trying to create a read only user. Any help is greatly appreciated.

Thanks guys for the tips. I have forgotten to mention that this situation happened only in a new created schema which has only a table and the table was exported from another oracle db( I pre-created the user with connect role and assign the tablespace etc), the import worked fine. Then I used a read only user(in different schema) to update/delete row to the imported table.The read only user can't update/delete other schemas besides from the new one. Is that I missed something when importing the table or pre-create user, tablespace, etc? Thanks in advance.

Deleting Schemas: What am I missing?

Hi.
I am on 11.2.0.3.0 - 64bit Production.
I have deleted a schema using DBMS_XMLSCHEMA.DELETESSCHEMA and delete_option 3.
I have then also deleted the resource using DBMS_XDB.DELETERESOURCE.
I then execute the XMLTYPE schemaValidate method on a record that was based on the schema just deleted and the result is an error that could only occur if the schema as still there (being more than one occurrence of an element that must have only one occurrence).
What am I missing?
Context: This is a development database and I am trying to replace an incorrect schema without having to spend a lot of time (slow performing system) migrating data using that schema.

OK. I have formulated a hypothesis while trying to get together a test case for this forum and Oracle support.
Originally I replaced the XSD only as a resource using the DBMS_XDB.DELETERESOURCE method. Life went on and eventually testing hit an error that lead me to believe I should have done something more.
I then discovered the DBMS_XMLSCHEMA.DELETESSCHEMA method and tried to use that in conjunction with the DBMS_XDB.DELETERESOURCE method. It was after this, when I could see the schema said one thing but the XMLTYPE schemaValidate method said something different, that I started this discussion and raised an Oracle Support call.
Since then, I have been restoring the DB and repeating tests in order to produce a test case, but everything has then been working as expected.
Hypothesis: Removing the XSD originally using only the DBMS_XDB.DELETERESOURCE method left the system in some sort of inconsistent state that the subsequent use of the DBMS_XMLSCHEMA.DELETESSCHEMA method could not correct.
Thanks to anyone who spent some time giving this some consideration.

Can not delete schema with RCU (Repository Creation Tool)

Hello together,

That sounds a little bit crazy for me then i have already give in the database connection details?
So why is the reason why i can not delete my choosen schema.
Give it another way to delete the schema.
I look forward for you help:)

Schema of a new Object Type: message pass the BIU without validation

Hi,
i've defined a new Object Type for send messages to Web Service. I've created the schema files and i've uploaded there in repository with the "Import" function of GUI. After, i've defined the XML file for the "Execute" function of the B1i GUI.
After the load of files, in the repository the files are in correct position.
In my BIU the definition of sender and receiver system type is correct, and also the definition of SenderMainObjectTypeID and ReceiverObjectTypeID. The message from B1 pass through the IPO chain without problems and the message is received by teh Web Service.
If modify the file XSL into the BIU, a message with less elements than a schema pass without problem.
If delete the schema from repository, the message pass without validation.
I would know because the schema is bypassed...
Thans

Ok,
solved with introduction of validation point in a customized IPO using a branch / unbranch atoms.
Bye.

9.2.0.6 performs better if stats are deleted

I have this behaviour with 90% of queries where deleting the schema stats makes it perform the best in some cases improvement of 300%.
The query was written for 9.2.0.6 and we never had 8i.
I have modified the optimizer settings in init.ora but never got close to the way rule based performs. What could be causing this?
I can post the query with 3 scenarios if anyone wants to look.
Thanks

Check the explain plans for the queries with and without statistics, that will tell you what's causing the performance difference. You may end up having to re-work some of the queries if you plan on switching to the cost based optimizer. We have applications that have never used statistics, generating them degraded performance and they were deleted. Application area decided they did not want to spend the time to rework the queries, I guess they'll do it when rule based goes away.
Good luck.
