Keeping pl/sql portlets state...

Hi!
I'll keep this as short as possible :)
On my Portal I have one pl/sql menu/navigation-portlet and one or more java portlets.
The menu portlet expands end extracts depending on where you click.
The menu knows its own state (the way it is extracted) by posting parameters (id's) whenever it's clicked on.
Url example:
http://host/portal/page?_pageid=35,66260&_dad=portal&_schema=PORTAL&menu.id=111&menu.p_id=222
By getting the parameters above the menu can restore/reload its own state.
Now to my problem:
When the user navigates to a page where I have a java portlet, the menu is extracted a certain way.
My javaportlet has navigation on itself.
When the user navigates by clicking a link on the java portlet the menuparameters are lost because the javaportlet can't see them, thereby the menus state is lost and "closed".
I find it very awkward/clumsy to put "menulogic" on all portlets in order to be able to keep the state of the menu.
The menuparameters must always be present somehow so that the menu knows how to restore its state!!!
Public parameters perhaps? (how do I make the parameters public for a pl/sql portlet?)
Any hints on how to solve this?

You would need to generate MobileXML from the portlet if it has to work with mobile devices. There is no automatic conversion from a regular portlet to a mobile portlet simply because the layout issues are vastly different on each mobile browser. However, you would only need to specify content in MobileXML once and this should work with most mobile browsers including WAP/WML, CHTML, TinyHTML etc. and cover most devices including PocketPC, Palm, Symbian etc. For the exact details of mobile-enabling a portlet, please refer to the Portal documentation. For advanced details on writing content for a mobile portlet, please see the wireless developer's guide.

Deepak

Keep log sql statement

Dear all,
Is there any ways to keep log sql statement after insert,update,delete as the example below :
==========================================
user01 client01 prog01.exe update emp set name='test';
user02 client02 prog02.exe delete from emp1;
I 'm not sure.Can use trigger? Is anybody have the example code?

Hi,
Here is a small resumen About Basic Auditing in Oracle.
For any Oracle versions prior to 9i you will need to set audit_trail parameter in the pfile ie.g.:
audit_trail = DBFor later Oracle Versions:
SQL>alter system set audit_trail = DB;To enable auditing for a specific object run the following command:
SQL>AUDIT SELECT, INSERT, UPDATE, DELETE ON SCHEMA.TABLE;To stop auditing use:
SQL>NOAUDIT SELECT, INSERT, UPDATE, DELETE ON SCHEMA.TABLE;Or to audit any statement that queries, delete, insert or updates any table, issue the following statement:
SQL>AUDIT SELECT TABLE, DELETE TABLE, INSERT TABLE, UPDATE TABLE;If you want to audit a specific user will need to run the following commands:
SQL>AUDIT ALTER TABLE, SELECT TABLE, INSERT TABLE, … ,GRANT PROCEDURE by <USERNAME>;To stop the audit for the user you will need to run:
SQL>NOAUDIT ALTER TABLE, SELECT TABLE, INSERT TABLE, … ,GRANT PROCEDURE by <USERNAME>;To see the results of the auditing use please run:
SQL> select * from dba_audit_trail;This is an excellent Oracle documentation to learn how to implement it:
- http://download-uk.oracle.com/docs/cd/B19306_01/network.102/b14266/cfgaudit.htm
Also I’ll recommend you to take a look on the following links:

Problem with public pages having PL/SQL portlets

I am having problem with a public page which has PL/SQL portlets.
When I try to access that page without doing login, it displays everything but the portlets which are database driven.
Is this the way this public page should behave?
Is there anyway by which I can display data to my public pages from PL/SQL portlets without doing login?
FYI PL/SQL portlets are in portal30 schema.

Yes, it has is_runnable function and it looks like this :
function is_runnable
p_provider_id in integer
,p_reference_path in varchar2
return boolean
is
begin
If p_reference_path is null the caller may be the provider
framework (i.e. the Refresh operation of the Portlet
Repository).
if (p_reference_path is null) then
The following if statement is the security mechanism that
the portlet implements. It does not have any other semantic
meaning. Any portlet is expected to implement their own
security mechanism.
This security mechanism checks if the current user is logged
on or just accessing the portal through the public account.
if (wwctx_api.is_logged_on) then
return true;
else
return false;
end if;
else
If p_reference_path is not null the caller makes this call as
a security check against the portlet instance.
The security mechanism implemented by this portlet for portlet
instances is null so true is returned. Returning this value
indicates that all users have access to this portlet instance.
return true;
end if;
end is_runnable;
+++++++++++++++++++++++++++++++++++++++++++
What should I need to change with that function? And what exactly is its use?
FYI : The code which I wrote for my portlet is by doing some modification in downloaded service portlet. But I have not altered is_runaable function.

T-sql case statement in a select

When I execute the following t-sql 2012 statement, the "NO Prod' value is not
being displayed from the sql listed below:
SELECT DISTINCT
IsNull(cs.TYPE,'') as type,
CASE IsNull(Course.TYPE,'')
WHEN 'AP' then 'AP Prod'
WHEN 'IB' then 'IB Prod'
WHEN 'HR' then 'HR Prod'
WHEN '' then 'NO Prod'
END AS label
FROM CustSection cs
INNER JOIN dbo.Person p on P.personID = cs.personID
Left join customCustomer cs564 on cs564.personID = p.personID and
cs564.attributeID ='564'
   where ( cs.type is null and cs564.attributeID = null)
     or
    (cs.type IN ('HR','AP') OR
      (cs.type='IB' AND SUBSTRING(cs.code,1,1)='3'))
ORDER BY label
What I want is for 'NO Prod' to be displayed when
cs.type is null and cs564.attributeId is null.
Thus can you tell me how to fix query above so the 'NO Prod' value is displayed in the
select statement listed above?

There is no CASE statement in SQL; we have a CASE expression. We do not use the old 1970's Sybase*- ISNULL(); we have COALESCE().
There is no such thing as a magic generic “type” in RDBMS. There is no such thing as a generic “code” in RDBMS. They have to to be “<something in particular>_type” and “<something in particular>_code” in a valid data model. How about blood_type
and postal_code??
There is no such thing as a generic “person” table in RDBMS. First of all, do you really have only one person, as you said?? But the important point is that these persons play a role in the data model – customers, students, etc. You are doing the wrong thing
and doing it badly. This table should not exist any more than a table of “Things” such exist.
And the reason you are beyond any real help is “attribute_id” which tell us that your schema is a total disaster of data and meta data mixed together in a non-RDBMS written in awful SQL. Based on cleaning up bad SQL for 30 years, it looks like you are an OO
programmer who never unlearned his prior mindset.
Why did you allow an encoding schema with blanks? Why do you have so many NULL-able columns?
SELECT DISTINCT is very rare in a properly designed schema. The DRI references assure that rows cam be matched. To get you started, look at this skeleton:
CREATE TABLE Products
(product_gtin CHAR(15) NOT NULL PRIMARY KEY,
product_type CHAR(2) DEFAULT 'XX' NOT NULL
CHECK (product_type IN ('AP', 'IB', 'HR', 'XX'))
The table name is a plural noun because it models a set (NOT an OO class).
The GTIN is an industry standard identifiers, and not have to invent our own.
The product_type (not blood_type, not automobile_body_type!) has a constraint that assures it is never NULL and never blank; I invented 'XX' as a default.
You need more help than you can get in a forum, but if you will follow Netiquette and post the DDL, we can get you started.

Sample PL/SQL Portlet Source Code for Oracle Portal 9ias

Hi, I'm a newbie of Oracle Portal technology, and I have a problem:
I would create a PL/SQL portlet that realizes the following functions:
1) Retrieve the username of the portal user logged from WWCTX_API.GET_USER function.
2) Insert into an oracle db table two values about two hidden fields in the HTML FORM of the portlet.
3) Realize the insert commit through the click on the submit button on the Html form of the portlet. I would redirect by the same button to an other page url also.
I've never developed in Portal, and may be useful if someone could post me the source code of the SHOW MODE SECTION in the PROCEDURE SHOW of a SAMPLE PL/SQL PORTLET that realizes the upper functions.
Thanks a lot....

Hi
Here's the code from Helloworld_Portlet example:
procedure show
p_portlet_record wwpro_api_provider.portlet_runtime_record
is
l_portlet wwpro_api_provider.portlet_record;
begin
if (not is_runnable(
p_provider_id => p_portlet_record.provider_id
,p_reference_path => p_portlet_record.reference_path)
) then
raise wwpro_api_provider.PORTLET_SECURITY_EXCEPTION;
end if;
Retrieve the portlet information.
l_portlet := get_portlet_info(
p_provider_id => p_portlet_record.provider_id
,p_language => p_portlet_record.language
if (p_portlet_record.exec_mode = wwpro_api_provider.MODE_SHOW) then
if (p_portlet_record.has_title_region) then
Draw the portlet header and specify what links are available
from that header (i.e. details, customize, help, and about).
The has_title property is set at the page region level.
wwui_api_portlet.draw_portlet_header
p_provider_id => p_portlet_record.provider_id
,p_portlet_id => p_portlet_record.portlet_id
,p_title => l_portlet.title
,p_has_details => true
,p_has_edit => true
,p_has_help => true
,p_has_about => true
,p_referencepath => p_portlet_record.reference_path
,p_back_url => p_portlet_record.page_url
end if;
Draw the portlet borders.
The has_border property is set at the page region level.
wwui_api_portlet.open_portlet(p_portlet_record.has_border);
Display the content of the portlet in the show mode.
Use the wwui_api_portlet.portlet_text() API when
generating the content of the portlet so that the
output uses the portlet CSS.
htp.p(wwui_api_portlet.portlet_text(
p_string => 'Hello World - Mode Show'
,p_level => 1
if (p_portlet_record.has_border) then
wwui_api_portlet.close_portlet;
end if;
elsif (p_portlet_record.exec_mode = wwpro_api_provider.MODE_SHOW_ABOUT) then
Display the about page for the portlet.
htp.p('Hello World - Mode Show About');
elsif (p_portlet_record.exec_mode = wwpro_api_provider.MODE_SHOW_EDIT) then
Display the edit page for the portlet.
htp.p('Hello World - Mode Show Edit');
elsif (p_portlet_record.exec_mode = wwpro_api_provider.MODE_SHOW_HELP) then
Display the help page for the portlet.
htp.p('Hello World - Mode Show Help');
elsif (p_portlet_record.exec_mode = wwpro_api_provider.MODE_SHOW_EDIT_DEFAULTS) then
Display the edit defaults page for the portlet.
htp.p('Hello World - Mode Edit Defaults');
elsif (p_portlet_record.exec_mode = wwpro_api_provider.MODE_SHOW_DETAILS) then
Display the details page for the portlet.
htp.p('Hello World - Mode Show Details');
elsif (p_portlet_record.exec_mode = wwpro_api_provider.MODE_PREVIEW) then
Display the preview page for the portlet.
htp.p('Hello World - Mode Show Preview');
end if;
end show;
I think you need to add this:
You can get the values of your html-form with this command:
v_hidden_1 varchar2(256);
v_hidden_2 varchar2(256);
v_hidden_1 := wwpro_api_parameters.get_value('name_of_hidden_1_in_html_form','p');
v_hidden_2 := wwpro_api_parameters.get_value('name_of_hidden_2_in_html_form','p');
You can get the actual URL with this command:
v_url := p_portlet_record.page_url;
Hope that helps.

Mark

MS SQL Server Statement could not be prepared. (WIS 10901)

Here is my situation. We are running Edge 3.0 using SQL Server 2005. I have a Webi report that I created with an existing Universe and the report is able to run fine. I didn't create the Universe, but I had to add new tables to the Universe.
For some reason when I went to create a System DSN to connect to the Universe, it didn't save the System DSN, but I was able to save it as a User DSN using the same name as the System DSN created on the BOXI Server. I was able to add the new tables and objects.
I then went to add the new objects to the existing web report and ran the query, I then received the error "A database error occured. The database error text is: [Microsoft][ODBC SQL Server Driver][SQL Server]Statement(s) could not be prepared.. (WIS 10901)". If I removed the new objects, I am able to run the Query fine.
When I add the new objects, I can look at the SQL, copy it and run it in MS SQL Server. Once I try to run the query with the new objects, I get the previously stated database error. Then I try to generate the SQL and get the message that Webi can't generate the SQL even though I was able to see the SQL if I hadn't run it.
I am not sure why I am getting this error, because the report is able to run before adding any new objects. Any suggestions would be helpful. Thanks

The issue was that I needed to get permission on my computer to create a system DSN and not use a local DSN. My local policy was changed on my computer.
But I am now writing a different report and getting the same error. Let me explain the situation.
The report was created and running fine, but the database was created by someone and it only contained partial data. The database is created in a star schema. I had to add more dimension tables. The fact table already had all the columns for the new dimension tables but had a default value of -1. Once I added the missing dimension tables, I reran the DI job that re-populated the fact table with data from all dimension tables. When I go now and run the report if I only run a query with the old dimensions, then the report runs fine and returns data. If I add a object from the newly created dimension fields then I get the error 'A database error occured. The database text is: ... Statement(s) could not be prepared. (WIS 10901)'.
I am not sure where the problem is. The report is using the same System DSN and the SQL created from the new dimensions works just fine in SQL Server Management Studio. We use Windows AD authentication and use an Windows users as our system account to access the database and it has read permissions.
Any help would be great. Thanks

Templates with pl/sql portlets

We plan to have several custom pl/sql providers. What do we have to do if we want to use templates and styles with our custom portlets?

Nilay,
PL/SQL portlets can (and should) utilize the wwui_api_portlet user interface portlet API package to render the portlet content. For additional font classes (not availble through the API) you can simply generate the appropriate HTML output using PL/SQL Web Toolkit (htp.p).

SQL CASE statement in XML template- End tag does not match start tag 'group

Hi All,
I am developing a report that has the SQL CASE statement in the query. I am trying to load this into RTF with report wizard and it gives me below error
oracle.xml.parser.v2.XMLParseException: End tag does not match start tag 'group'
Does XML publisher support CASE statement?
My query is something like this
SELECT customercode,
SUM(CASE WHEN invoicedate >= current date - 30 days
THEN balanceforward ELSE 0 END) AS "0-30",
SUM(CASE WHEN invoicedate BETWEEN current date - 60 days
AND current date - 31 days
THEN balanceforward ELSE 0 END) AS "31-60",
SUM(CASE WHEN invoicedate < current date - 60 days
THEN balanceforward ELSE 0 END) AS "61>",
SUM(balanceforward) AS total_outstanding
FROM MyTable
GROUP BY customercode
ORDER BY total_outstanding DESC
Please advice if the CASE statement or the double quotes are causing this error
Thanks,
PP

I got this to work in the XML but the data is returning zeros for all the case statements. When I run this in toad I get results for all the case conditions but when ran in XML the data displayed is all zeros. I am not sure what I am missing. Can someone shed some light on this please
Thanks!

Parsing an OPEN SQL select statement

Hi all,
I want to parse an open SQL select statement to get the list of tables and the corresponding fields in the select statement.
Is there some ABAP-internal syntax from the SAP Database Interface that does this? or is the only option to do this is to manually break the statement?
Thanks.
Girish

Hi,
I doubt if there is something like that available to use. It think you will have to write a parser for yourself.

Java.sql.SQLException: Statement cancelled, probably by transaction timing

Hi all,
I have a problem with transaction handling over 2 applications. I have 2 EAR files (*A.ear* and B.ear) which are deployed on a WLS 12.1. The WLS contains a XA datasource which is connected to a Oracle XE database. Both applications are using the same datasource. The datasource is configured to use the driver oracle.jdbc.xa.client.OracleXADataSource.
EAR A contains a Remote EJB which is is calling a local EJB. The local EJB calls a Remote EJB from EAR B.
Here is an example how the code looks like:
@Remote
@Stateless(mappedName = "AnyRemote", name = "AnyRemote")
public class AnyRemoteBean implements AnyRemote {
    @EJB
    private AnyLocal anyLocal;
    @Override
    public void doIt() {
        anyLocal.doSomething();
@Local
@Stateless(mappedName = "AnyLocal", name = "AnyLocal")
public class AnyLocalBean implements AnyLocal {
    @PersistenceContext(unitName = "A")
    private EntityManager entityManager;
    @EJB(mappedName = "AnyCompositeService")
    private AnyCompositeService anyCompositeService;
    @Override
    @TransactionAttribute(TransactionAttributeType.REQUIRES_NEW)
    public boolean doSomething() {
            try {
                 // do some stuff and save to database within another local EJB
                anyCompositeService.doSomethingOnEAR_B();
                return true;
            } catch (final AnyException e) {
                LOGGER.error("doSomething failed", e);
                return false;
    @Override
    @TransactionAttribute(TransactionAttributeType.REQUIRES_NEW)
    public boolean stayOnEar_A() {
            // do some stuff and save to database within another local EJB
            return true;
}AnyCompositeService located in EAR B looks like this:
@Remote
@Stateless(mappedName = "AnyCompositeService ", name = "AnyCompositeService ")
public class AnyCompositeServiceBean implements AnyCompositeService {
    @Override
    public boolean doSomethingOnEAR_B() throws AnyException {
        // do some calls to some local EJBs and some other remote EJBs and save something to database
        return true;
}In this process of EAR B I'm using the entitiy manager:
    @PersistenceContext(unitName = "B")
    private EntityManager entityManager;persistence.xml for EAR A looks like this
    <persistence-unit name="A" transaction-type="JTA">
        <provider>org.hibernate.ejb.HibernatePersistence</provider>
        <jta-data-source>MyDatasource</jta-data-source>
       
        <properties>
            <property name="hibernate.transaction.jta.platform"
                value="org.hibernate.service.jta.platform.internal.WeblogicJtaPlatform" />
            <property name="hibernate.max_fetch_depth" value="3" />
            <property name="hibernate.connection.characterEncoding" value="UTF-8" />
            <property name="hibernate.connection.charSet" value="UTF-8" />
            <property name="hibernate.connection.useUnicode" value="true" />
            <property name="hibernate.default_batch_fetch_size" value="20" />
        </properties>
    </persistence-unit>
</persistence>persistence.xml for EAR B looks like this
    <persistence-unit name="B" transaction-type="JTA">
        <provider>org.hibernate.ejb.HibernatePersistence</provider>
        <jta-data-source>MyDatasource</jta-data-source>
       
        <properties>
            <property name="hibernate.transaction.jta.platform"
                value="org.hibernate.service.jta.platform.internal.WeblogicJtaPlatform" />
            <property name="hibernate.max_fetch_depth" value="3" />
            <property name="hibernate.connection.characterEncoding" value="UTF-8" />
            <property name="hibernate.connection.charSet" value="UTF-8" />
            <property name="hibernate.connection.useUnicode" value="true" />
            <property name="hibernate.default_batch_fetch_size" value="20" />
        </properties>
    </persistence-unit>
</persistence>As you can see the method doSomething() defines the transaction attribute TransactionAttributeType.REQUIRES_NEW.
When I execute AnyRemote.doIt() I get the following exception:

Does anybody know what is the issue here? Is there any configuration I have overseen?

That is a WLS internal message. The statement did get cancelled,
probably as a part of the process of rolling back the transaction it
was involved in. If you don't find your core problem, open an
Oracle support SR, and we could help debug this further.

Java.sql.SQLException: Statement cache size has not been set

All,
I am trying to create a light weight SQL Layer.It uses JDBC to connect to the database via weblogic. When my application tries to connect to the database using JDBC alone (outside of weblogic) everything works fine. But when the application tries to go via weblogic I am able to run the Statement objects successfully but when I try to run PreparedStatements I get the following error:
java.sql.SQLException: Statement cache size has not been set
at weblogic.rjvm.BasicOutboundRequest.sendReceive(BasicOutboundRequest.java:108)
at weblogic.rmi.internal.BasicRemoteRef.invoke(BasicRemoteRef.java:138)
at weblogic.jdbc.rmi.internal.ConnectionImpl_weblogic_jdbc_wrapper_PoolConnection_oracle_jdbc_driver_OracleConnection_812_WLStub.prepareStatement(Unknown Source)
i have checked the StatementCacheSize and it is 10. Is there any other setting that needs to be implemented for this to work? Has anybody seen this error before? Any help will be greatly appreciated.
Thanks.

     at oracle.jdbc.dbaccess.DBError.throwSqlException(DBError.java:269)Hi. Ok. This is an Oracle driver bug/problem. Please show me the pool's definition
in the config.xml file. I'll bet you're defining the pool in an unusual way. Typically
we don't want any driver-level pooling to be involved. It is superfluous to the functionality
we provide, and can also conflict.

PL/SQL Portlets accessed through WAP

Hi,
we have developed some PL/SQL portlets (using portal 10g version 9.0.4.0.99) which needs to be accessed in a WAP enabled mobile. need some documents or references for the same.
Thanks
Ramya

You would need to generate MobileXML from the portlet if it has to work with mobile devices. There is no automatic conversion from a regular portlet to a mobile portlet simply because the layout issues are vastly different on each mobile browser. However, you would only need to specify content in MobileXML once and this should work with most mobile browsers including WAP/WML, CHTML, TinyHTML etc. and cover most devices including PocketPC, Palm, Symbian etc. For the exact details of mobile-enabling a portlet, please refer to the Portal documentation. For advanced details on writing content for a mobile portlet, please see the wireless developer's guide.
Regards,
Deepak

ESI with pl/sql portlets

Is it possible to use ESI within pl/sql portlets?
The idea being to only re-execute the query and redraw the resulting HTML rather than re-load the whole portlet.
Any ideas ?

Not sure. I'll look into it. In the meantime, you may get a faster response if you repost your question to the Portal Caching forum. A lot more Portal expertise there.

Using column number inplace of column name in SQL Select statement

Is there a way to run sql select statements with column numbers in
place of column names?
Current SQL
select AddressId,Name,City from AddressIs this possible
select 1,2,5 from AddressThanks in Advance

well, ok, it's not possible with SQL, but how about PL/SQL?As mentioned, using DBMS_SQL you can only really use positional notation... and you can also use those positions to get the other information such as what the column is called, what it's datatype is etc.
