Wwctx_api !

Hi Dmitry,
Thanks for the reply .
If i hardcode it and run the report then it gives the results within no time .
The problem is when i directly compare it using the api in the SQL, it takes a lot and lots of time only to give the mesg ' page expired / timed out '.
I did a work-around by calling the api in the before page display plsql and then pass it as a parameter to the report .This works fine .
( However this gives a problem when i have a parameter report , the user parameter gets un-necesarily displayed in the parameter form .)

Vijaya

What schema is your procedure running in?
Is it called from the web?
You need to do the following...
- the request needs to come from the web, so that the session context is set, with an appropriate session cookie.
- if your code is not in the portal schema, then it must be in another schema on which you have run the script provsyns.sql
in order to gain access to the appropriate APIs (such as wwctx_api).
- if the user has logged into the portal, then you need to run the session context check against the portal schema, e.g.,
portal30.wwctx_api.get_user -- not in orasso.
Hope that helps.

How do you use PORTAL .WWCTX_API.GET_USER

Hi. I'm a newbie at Portal and Oracle and am having a problem extracting the userID for the logged user. I have
a form that needs to be populated with the login ID for that session. What exactly do I need so that the field will
auto-populate with the user's ID. Do I enter the api in the "Default Value" box of the form for that field? What do I need
to select from the "Default Value Type" dropdown?
Also, because I'm populating the form with data from the database (it's an update record form), I'd like to "blank" the
comment field rather than populate it with the info from the DB record. Is that possible?
Finally, is there any recommendations on manuals or other books to purchase that would answer these types of
questions. I feel that this is a pretty basic task and should be in a manual somewhere.
Thanks,
Ron

Hi,
In the default value column specify <portalschema>.wwctx_api.get_user. In the default return type make it "function returns varchar".
This should help.
Thanks,
Sharmila

Wwctx_api.get_user in Dynamic Page?

Can API calls be made from select statements within the <ORACLE></ORACLE> tags in Dynamic Pages? The following query should list courses that someone has signed up for but the query cannot be saved within the Dynamic Page:
<ORACLE>
select course_name
from course
where user_id = wwctx_api.get_user
</ORACLE>

Jay,
Just prefix the function with "PORTAL30" (or the name of the schema where Portal is installed, if not PORTAL30).
<ORACLE>
select course_name
from course
where user_id = PORTAL30.wwctx_api.get_user
</ORACLE>
null

WWCTX_API.GET_USER

I created a custom folder and typed following sql in that:
SELECT WWCTX_API.GET_USER from dual
there was no problem in creating this folder.
When i create a worksheet in plus and while running a query, its giving following errors
ORA-14551: cannot perform a DML operation inside a query.
ORA-06512: at "PORTAL.WWCTX_SSO",line 2954
ORA-06512: at "PORTAL.WWCTX_SSO",line 3483
ORA-06512: at "PORTAL.WWCTX_SSO",line 1735
ORA-06512: at "PORTAL.WWCTX_SSO",line 2954
ORA-06510: at PL/SQL: unhandeled user-defined exception
ORA-06512: at
Actually one of my query is based on SSO user id.
When i use this "SELECT WWCTX_API.GET_USER from dual;" on SQL prompt. Its doesn't give any error.
I need to use this WWCTX_API.GET_USER in my query. Any idea why its giving error in discoverer plus?
Thanks

Using wwctx_api.get_user in dbms_rls policy

We have not been able to succesfully use a call to wwctx_api.get_user in the function we use as a policy for row level security. The package compiles fine. The policy adds fine. When we try to select from the table where the policy is on from portal (LOV, REPORT, DYNAMIC PAGE) we get Ora-28112.
Help?

The error code maps to the following message:
ORA-28112 failed to execute policy function
Cause: The policy function has one or more error during execution.
Action: Check the trace file and correct the errors.
Could you try returning a static value from the security policy and do your select and see if that works.

HELP!!! wwctx_api.get_user

I created a PL/SQL Server Page just to show the login information from a login portlet.
The code follows:
<%@ page language="PL/SQL" %>
<%@ plsql procedure="logininfo" %>
<HTML>
<HEAD><TITLE>This is a PSP Page!</TITLE></HEAD>
<BODY>
<%
declare
myname varchar2(50) := portal30.wwctx_api.get_user;
begin
htp.print(myname);
end;
%>
</BODY>
</HTML>
My Login portlet on success "P_request_url" calls for the above procedure.
My problem was no matter what user I logged on with, it always dispays "PUBLIC" as the login user. What I need is to get oracle portal user who is curently using the session. WHY? Please Help!
Thanks!

there is a diffence between portal.wwctx_api.get_user and portal_sso.wwctx_api.get_user. Check and make sure you are using the api from the right context. You're probably getting the sso user and not the portal user.

However, you are probably looking for the default group name for a given user. Please see wwsec_api.get_defaultgroup.
look into wwsec_api.get_list_members for a list of members in a group.
The links to APIs that Opportalist presented should lead you to the descriptions of both functions.
hope that helps!

Lov populated with wwctx_api.get_user

Hi Friends ,
I am trying to pull the records in to LOV based on the user login .."select dist from sometable where sname ='wwctx_api.get_user' ,,,But it is not returning any records ..Any help ..thanks in advance ..
Vi

Hi,
I think the single quotes is the problem. It is trying to find a record with the sname = 'wwctx_api.get_user'. It should be
select dist from sometable where sname = wwctx_api.get_user
Thanks,

Lack of performance using portal30.wwctx_api.get_user to limitrecords in portlets

Hi,
I have a portal page using 5 reports as portlets each of them use
"where personid = portal30.wwctx_api.get_user"
to limit the amout of data retrieve for each user.
I have 250 users registred in login server whose can use this page.
The 5 portlets fall in timeout every time, except if I replace "portal30.wwctx_api.get_user" by a constant,
which is not very useful but works.
Any idea to avoid usage of this API.
Thanks in advance

Hi,
Instead of using the api in the query, use a bind variable and then customize the report to pick up the value from the api. Here is an example
1) Create a sql report
select * from usertab
where user_id = :userid
2) Publish this report on a page
3) Now edit the page and go to the edit defaults of the report.
4) You will have a textbox against userid. Here you enter #<portalschema>.wwctx_api.get_user
Please replace the portalschema with the name of your portal schema.
Thanks,

Wwctx_api.NO_SESSION_EXCEPTION

Hi,
I have the following problem (I'm very new to writing portlets, so maybe I'm just overlooking something stupid..?):
I have created a new schema "portal_pckg" (via 'Create new schema' in Portal) in which we are planning to store plsql-packages to use in portlets.
In a plsql_package I wrote a function that returns portal30.wwctx_api.get_ip_address();
I then make a call to this function from a Javaportlet.
When I test the portlet (logged in as portal30-portal30) the portal30.wwctx_api.NO_SESSION_EXCEPTION is raised.
why ?
Thanks in advance for any ideas,
Heidi

Thanks Dietmar. Yes this is cool behavior :-) Now I have the user how do I check in the OID if the user is member of a certain group? I was planning to use portal.wwsec_api.is_user_in_group but when this is not possible what then? dbms_ldap?
I just found another post that suggested using wwv_flow_ldap.is_member. It't works fine:
wwv_flow_ldap.is_member
( p_username => v('APP_USER'),
p_pass => null,
p_auth_base => 'cn=users,dc=wmdata,dc=dk',
p_host => 'wmsi0q2071',
p_port => 389,
p_group => '101vis_global_sag',
p_group_base => 'cn=users,dc=wmdata,dc=dk'

Help: Portal calendar error when using wwctx_api.get_user

Hi,
I am trying to create a calendar based on some table data and results should be specific to portal user logged in. So I have created following query but it does not filter the data based on the user logged in. I have checked and there are no issues on data side.
select
a.EVENT_START_DT the_date,
a.EVENT_NAME the_name,
( ) the_name_link,
null the_date_link,
null the_target,
null the_intermedia
from TBL_EVENTS a
where a.Event_Status = 0
and a.event_personal = 1
and a.event_recorded_by = (select entryid FROM ods.CT_UID where upper(ATTRVALUE) = upper(wwctx_api.get_user))
order by a.event_id desc
Failing above I also tried other way using bind variable and then passing the page paramater (selecting system variables USER_NAME) to the bind variable
Select a.EVENT_START_DT the_date,
a.EVENT_NAME the_name,
( ) the_name_link,
null the_date_link,
null the_target,
null the_intermedia
from TBL_EVENTS a
where a.Event_Status = 0
and a.event_personal = 1
and a.event_recorded_by = (select entryid FROM ods.CT_UID where upper(ATTRVALUE) = upper(:username))
order by a.event_id desc
However it still dont work.
Can anyone please give me any suggestion or way to resolve this.
Any help much appriciated.
Thanks
Ganesh

Hi,
I am storing OID user id but I am comparing as follows
select
a.EVENT_START_DT the_date,
a.EVENT_NAME the_name,
('' ) the_name_link,
null the_date_link,
null the_target,
null the_intermedia
from TBL_EVENTS a
where a.Event_Status = 0
and a.event_personal = 1
and a.event_recorded_by = (select entryid FROM ods.CT_UID where upper(ATTRVALUE) = upper(portal.wwctx_api.get_user)
order by a.event_id desc
but this comes with following error
Unable to describe SQL statement. Please correct it (WWV-13010)

I then tried creating bind variable as follows
select
a.EVENT_START_DT the_date,
a.EVENT_NAME the_name,
('' ) the_name_link,
null the_date_link,
null the_target,
null the_intermedia
from TBL_EVENTS a
where a.Event_Status = 0
and a.event_personal = 1
and a.event_recorded_by = (select entryid FROM ods.CT_UID where upper(ATTRVALUE) = upper(:musername)
order by a.event_id desc
and then passing system variable USER_NAME to musername in page parameter settings to the portlet.
Please advise help
Thanks

WWCTX_API equivalent in 9.0.2.6

Jerry/Oracle,
Will 9.0.2.6 see the re-introduction of what was in old speak the Content Area APIs into Portal?
I'm assuming it must be the case otherwise it would not be much of an upgrade release! The 9iAS 9.0.4 white paper did not mention anything in this important area.
Cheers,
John

Yes, the 9.0.2.6 release will re-introduce the content area APIs and views. They are backward compatible with 3.0.9 for the most part - there are a few minor changes, some deprecated parameters, and some new functionality. The documentation will be much improved as well.
Regards,
Jerry

Wwctx_api.get_user only returns PUBLIC

I am trying to determine the user who has logged onto Portal, but this package only returns PUBLIC. I've seen in previous postings that this is the package to use - what am I doing wrong?

Well, I'm almost stumped. As far as I know, you are in a different context when executing a PL/SQL routine directly through the DAD. The username & password are stored with the Portal DAD (similar to old OAS functionality), so the engine doesn't know who you are. You can try using a different DAD w/o username and password stored, but then you'd have to create database schemas for all of your users. In this case, you would probably have to use an OWA package to find out who they are, because they are not logged in to Portal.
A better solution might be to create Forms based on Stored Procedure components for all of your procedures, which would enable you to keep the users in the Portal context. You would just have to create at least one (dummy) parameter for each, because forms based on stored procedures need a parameter.

Wwsec_api / wwctx_api JPDK implementations

PL/SQL PDK provides functionality to programmatically work with security and portal context. Does there exist JPDK implementations for this functionality and to what extend are these implemented?

guess not! How about it Sue, or maybe we should post this question in the Oracle9iAS Portal Content Areas discussion?

Wwctx_api !
