Parameters to pl/sql pages

Hi all,
I installed the pdk examples showing how to pass parameters betweens pl/sql portlets. I saw it but not understand very weel. This is the same way to pass parameters between pl/sql pages? Is there any step-by-step that explain how to make the parameters passing more simple?
Best regards,
Joao Vitor.

Hi Mick,
Thanks for your reply. However my problem is still not resolved.
I have created a Omniportlet with lists the staff details. When I click on the staff link I am passing to parameters as follows
http://servername/pls/portal/url/PAGE/CCM_MIS_PORTAL/TUTOR_HOME/Course_Info?Param1=10017031/M2523&Param2=001434
on the receving page I have a omni portlet which must receive these 2 parameters and pass it on to the query and filter the results.
On the received page I have created 2 page parameters (Param1 and Param2)
I have assigned these 2 paramaters to the portlet paramers through page parameters' section
on the omni portlet in the query I have created 2 bind variables (p1, p2) and the default value of the bind variable is set using ##Param1## and ##Param2## so the received values from page is passed to to bind variable and hence to the query.
However the omni portlet is not received the parameters and I can not figure out whats wrong?
Is there any problem with my URL (guide says I should use relative URL)
Please help

Page Parameters in PL/SQL Pages

The OAS User's Guide says:
"You can define page parameters for PL/SQL Pages. Values for these parameters are passed to bind variables in the PL/SQL code. For example, if the PL/SQL page 'myplsqlpage' contains the PL/SQL statement 'a:=:param1'; and a page parameter is specified named 'param1' with the value '123' (param1=123), this URL is used to access the PL/SQL page in Oracle AS Portal:
http://myportal/myplsqlpage?param1=123
In the PL/SQL code, the bind variable 'a' is assigned the value '123'."
But I did that but I have the following message:
ORA-01008: not all the variables have been binded (WWS-22518).
Please I have an example.
Thanks in advance.

Hi Patrick,
Your suggestion seems interesting and simplistic and I wonder if you could make it working. Because, I worked on a similar suggestion some months ago and it did not work. unless I am confusing your idea with something else, it is not designed to work - although it was claimed in the documentation to work. On talking to Oracle we were able to pin down that it was a documentation bug and a new note was created to state that.
You may wanna see the following Metalink Note which says that passing parameters from a PLSQL page is not allowed.

Subject: Unable To Pass Parameters To A PL/SQL Page
Doc ID: Note:550373.1
Cause
Page parameters were not designed to work with PL/SQL pages. However the Oracle® Application Server Portal User's Guide states that this is possible.
This is a documentation bug and it is related to the following unpublished bugs:
BUG 5007570: GET PARAMETERS IN PL/SQL PAGE
BUG 3473023: PASSING PARAMETERS TO PL/SQL PAGE IS ERRORING OUT - ORA-1008
Solution
-- To implement the solution, please execute the following steps::
PL/SQL pages do not support to pass parameters. If you need to pass page parameters to a database provider components such as forms and reports, then you need to create a simple page and follow notes below:
Note 265180.1
Title: How to pass parameters to a form, which is placed as a
portlet inside a page?
Note 287545.1
Title: How Pass Parameter Via URL to a Report Using Page Parameters

Pass parameters from JSP Dyn Page to WDJ Application

Hi,
I am trying to pass parameters from my JSPDyn Page to WDJ Application.
I am using NWDS 7.1 EHP1
My code is :
function to_WEBDYNHK()
      EPCM.relaxDocumentDomain();
      EPCM.doNavigate
    ('ROLES://pcd:portal_content/Himanshu.Himanshu/TestDynUIApp?DynamicParameter="hkparam%3Dqwertyuio"');
This method is being called on click of a button.
hkparam is the parameter in question.
The JSPDyn page is an iView and the WDJ application is a page and both have been assigned to a role.
In the properties of the WDJ Page, I have removed DymanicParameter from "Do not Forward These Parameters To Web Dynpro" property.
However I am getting null as the value of hkparam in my WDJ application.
The code used is :
IWDRequest request = WDProtocolAdapter.getProtocolAdapter().getRequestObject();
       String param1= request.getParameter("hkparam");
What seems to be missing here.
Please help.
I went through the documentation on SDN but it does not seem to help.
TIA,
Himanshu

Hi Himanshu,
Try this code.
EPCM.doNavigate("ROLES:portal_content/Himanshu.Himanshu/TestDynUIApp?hkparam=Dmypass1123")
if the parameter is hkparam and the value to be passed is Dmypass1123. You need not change any design time property of the WD page, and WDProtocolAdapter should retrive the parameter.

Vishweshwara P.K.M.

Named parameters in Native SQL

A little background first:
Our website uses Hibernate as it's JPA provider, but we've run into several issues with it, one of which they actively refuse to fix out of pure arrogance, even when we gave them a good patch for it. The other one is a performance issue that can be greatly improved by passing arrays as parameters, which I've read rumours is supported in EclipseLink. I first tried implementing a Hibernate UserType as they've specified and it turns out they never read them into the Map that looks-up parameter types during binding, even though it's loaded from their hibernate.cfg.xml. In other words, they're only pretending to support custom user types, but unless you're writing-out the full manual loading of their configuration, there's no way to do it.
After a day of trying to fix all the relation annotations that EclipseLink finds unacceptable in our project (which only uses native SQL and EntityManager.find for selects) I finally got it running and came to discover you don't support named parameters in native SQL. That was really disappointing, because a few months ago we migrated all our queries to named parameters, because positioning ones were too difficult to track and caused more bugs when we had to add more criterias.
My questions are these:
Are named parameters for native SQL not supported by JPA specifications or because they are considered low priority?
Would you accept a patch that supports them?
Can we really use arrays and/or lists as parameters in queries like this "SELECT * FROM some_table WHERE my_column_a IN ? AND my_column_b NOT IN ?"
If yes to above, would it still work if the first one is an array of integers and the second is an array of strings?
Would it work if it's in native SQL and the column types cannot be resolved due to query complexity?

Read parameters in a dynamic page portlet?

Hi,
Is it possible to read input parameters in a dynamic page portlet?
Am I missing something if I want to read the input_parameter?
<oracle>
ftp.p(:input_paramter)
</oracle>
Thanks a lot.

Hi,
It is not possible to read the input parameters in the <oracle> tag. You can read it in the additional plsql code. If you have
to access the parameter deptno then do this in the additional plsql code section.
for i in 1..p_arg_names.count loop
if p_arg_names(i) = 'deptno' then
htp.p(p_arg_names(i));
end if;
end loop;
Thanks,

Now situation is after search when I will click on Details button on the search results table the custom Web PL/SQL page should be called.
But I am not able to figure out how to do it. Could anybody be able to help me on this ?

You have to set the destination property of the button to call your WebPL/SQL page.

Where can i find the SQL page in the enterprise manager?

Hi everybody
i want to execute a number of indexes on my database, so i thought of 2 ways but each way has a problem:
1) copy and paste the contents inside SQLPLUS, but this will cause an error that every line should ends with ";"
2) execute the file contains the indexes "createindexes.sql" inside SQLPLUS by using the commnad "@ createindexes" and the SQLPLUS by default will know that it is ".sql", when i try this way it gives me the following error although i am sure that i connect correctly by the right schema and password:
SQL> @D:\TPoX.v1.3\TPoX\Oracle\ddl\createindexes.sql;
CREATE INDEX security_idx ON "security" (sdoc) INDEXTYPE IS XDB.XMLIndex
ERROR at line 1:
ORA-00942: table or view does not exist
CREATE INDEX custacc_idx ON "custacc" (cadoc) INDEXTYPE IS XDB.XMLIndex
ERROR at line 1:
ORA-00942: table or view does not exist
CREATE INDEX order_idx ON "order" (odoc) INDEXTYPE IS XDB.XMLIndex
ERROR at line 1:
ORA-00942: table or view does not exist
lastely, someone told me to copy and paste them inside the SQL page exists in the enterprise manager, but i don't know where, i searched a lot for it but i didn't find it. please help
thx
Dina

Are you sure that your table name is lower case
Can you do the following commands in SQLPLUS
desc security
desc "security"
desc SECURITY
Also, can you tell us more about what your are doing with TpoX

Generic Apache calling OAS for pl/sql pages

I have a generic apache 2.2 set up using SSL and everything works fine. We are calling OAS v10.1.2 for pl/sql pages. This works fine. Now we want to use SSL certificates. The certificates are correct for the generic apache, but when I call the pl/sql it doesn't work.
1. If we have SSLVerifyclient OPTIONAL on the apache 2.2 the call to pl/sql is correct and the certificate is generated, but not for the pages on the apache 2.2. server.
2. If we remove SSLVerifyclient OPTIONAL on the apache 2.2 the ssl certificate is correct for the pages on the apache 2.2 but not for the pl/sql pages form the OAS.
Where should the ssl certificate come from for the OAS pl/sql? The OAS server or the generic apache server?

Passing System Parameters to sqlplus_exec_template.sql

Hey All,
I am running into problems passing system parameters to a SQL Loader mapping from within a shell script, and I hope someone can pick out what I am doing incorrectly. My call is as follows:

I am using the system parameters defined in Note 292399.1, and I have tried several variations on syntax. Any help would be greatly appreciated.
David

Well, I answered my own question. It appears that even though note 292399.1 lists data_file_name and log_file_name, they are not modifiable at execution using sqlplus_exec_template. Only those parameters modifiable at execution time using the Deployment Manager can be changed. I tested this using BINDSIZE=5000000, and it ran without a problem.

Passing Request Parameters to Non JSF Page

I want to pass request parameters from a JSF page (Page1.jsp) to a non JSF page (paramTest.jsp) and am having trouble.
The parameters are 'null' in the non JSF page.
Here is code (in Page1.java) that is called when 'button1' is clicked in Page1.jsp (modified from JSF, Bergsten p.167):
public String button1_action() {
        FacesContext context = javax.faces.context.FacesContext.getCurrentInstance();
        ExternalContext ec = context.getExternalContext();
        try {

think the Problem is in the Configuration from mod_plsql.
When i try to access a PL/SQL Page through the Gateway, then it comes the same issue.
I can reconstruct the Problem on a fesh installed Database XE on Windows XP and on Linux.
After installation, i can Access the Login Page from APEX. The System works correct.
After i try to get the URL "http://127.0.0.1:8080/xdbconfig.xml" i get a Browser Login.
I typed in the System Account, then i can see the xdbconfig.xml.
After that i can't access APEX or any other PL/SQL Page
I can only access the XML DB Repository Directories.
Can someone help?
Thanks
Jan Hoelscher

I noticed the same issue with session info (after login in and then unlocking anonymous) still in the cookie or in memory (at least I think so).
After restarting the browser windows (all windows of the same "brand") - problem has disappeared
