Session variable type in repository

Hi,
I would like to define a session variable with type INT, where in the Admin tool that I can define it?
ex: I first created a initialization block,( select a from b where id =:USER) a is a NUMBER type in the database, but it always returns an integer, when I create a session variable to contain the return of this init block, it gives me 4.0 instead of 4. I tried to use cast (a as INT) it still gives me 4.0. How can I define the session variable as INT type?
Thanks,

Hi Meli,
one thing do you want to int type or real type value in the out put..
As you said,
it gives me 4.0 instead of 4. I so, you want decimal value then why did you cast it to int?
And at last your question again
How can I define the session variable as INT type?the example you given (with 4.1) and your question is not matching..
please give clear picture what do you want?
Anyhow, Check that particular column datatype in physical layer, is that int or some other?
if you want decimal values like in database, physical column data type must be non int.
change it.. and try

Session Variable in filter view error

Hello,
My prompt is defaulted to current 12Weeks. I used session variable in the prompt to capture 12 Weeks (Current Week and Current+12).
so the default value is @{biServer.variables['NQ_SESSION.PERIOD_STDATE']} where PERIOD_STDATE is my session varible.
I am using a filter view to display the filters being applied.
When the user opens a tab, the filter view is throwing error
***The syntax of the expression to be evaluated is invalid.***
***Expression: @{biServer.variables['NQ_SESSION.PERIOD_STDATE']}***
My report is running fine. I just have the date column as prompted in my report request.
When the user hits go button on the prompt then the filter view comes up just fine.
What is that I am doing wrong? Why does the filter view gives result after hitting GO button?
Please help.
thanks,
deep

Hi,
1. Set the default using logical SQL. Select <presentation table>.<presentation column> from <subject area> where <presentation table>.<presentationation column> =valueof(NQ_SESSION.<session variable>)
2. You dont have to write the exact syntax for entering the session variable in the default values. You just need to use the session variable name after selecting the session variable type in the drop down.
Hope this helped/ answered.

Problem with Session variable initialization block

Hi,
I'm getting strange results when using session variables in my repository files.
I have created session variables as specified in the document which is available at
http://www.oracle.com/technology/obe/obe_bi/bi_ee_1013/bi_admin/biadmin.html
The main problem getting with the system session variable (USER) in the select statement.
My select statement is as follows,
select ':USER',case when upper(':USER') = 'KUMAR' then 'APR-05' end from Dual
The problem is while logging into the BI Answers it is allowing all the invalid users to login who does not exist.
when i remove the quotes and simply use :USER in the select statement it is not allowing the invalid users to login but giving error while displaying the results.
when i remove the user variable from select statement its giving correct results.
Can i know what is causing the problem.
Thanks,
Kumar.

Passing Session variable of DATE data type to opaque view filter

Hi Everyone,
Can you guys please help me in passing session variable of DATE data type in RPD's physical layer 'opaque view' filter for Oracle database
I tried following syntax, syntax wise I didn't got getting any error, but at the same time this opaque view is not fetching any records as well. my session variable is "END_DATE" and its value is 1998/12/31:00:00:00(as shown in RPD session windows, datatype is DATETIME)
SELECT AMOUNT_SOLD, CHANNEL_ID, CUST_ID, PROD_ID, PROMO_ID, QUANTITY_SOLD, TIME_ID FROM SH.SALES
WHERE TIME_ID =TO_DATE( 'VALUEOF(NQ_SESSION.END_DATE)','MM/DD/YYYY')
SELECT AMOUNT_SOLD, CHANNEL_ID, CUST_ID, PROD_ID, PROMO_ID, QUANTITY_SOLD, TIME_ID FROM SH.SALES
WHERE TIME_ID = TO_DATE( 'VALUEOF(NQ_SESSION."END_DATE")','MM/DD/YYYY')
SELECT AMOUNT_SOLD, CHANNEL_ID, CUST_ID, PROD_ID, PROMO_ID, QUANTITY_SOLD, TIME_ID FROM SH.SALES
WHERE TRUNC(TIME_ID) = TO_DATE( 'VALUEOF(NQ_SESSION."END_DATE")','MM/DD/YYYY')
In past, I was able to pass a session variable into a opaque view filter using DATEOF function, but that was in DB2.
I appreciate your time and help

Finally, I got right format. here it is
to_date(substr('valueof(NQ_SESSION.END_DATE)',1,10), 'yyyy-mm-dd')
and here is the source from where I got this information

Session Variable : How to find out where all it is used in the repository?

Hello Everyone,
We have a requirement where we need to convert a few session variables into repository variables. For this we need to figure out where all is that session variable used in the repository and webcat (which all logical columns use it, which all prompts use it etc). We tried the query repository utility but that didnt help. Is there any other way to find that out? Will really appreciate any pointers from your side.
Thanks in Anticipation,
Karan

Hi,
To find the variables used in,
Rpd : Open the rpd->Navigate to Tools Menu->Select "Utilities"->"Repository Documentation".This will generate a csv file with the associations
Webcat :Open the webcat using catalog Manager->Tools Menu->Create Report-.Select the desired columns (Include Xml column)->Open the rpeort in excel find "Variable"->from this you can find the various variables used in the catalog.

To pass new session variable value to stored proc before running a report.

Hi,
Below is summary of the report requirement -
Database level design
1. Created a view and a global temporary table (GTT)
2. Created an Oracle package procedure to accept from and to business dates on basis of which it will fetch, process and populate the GTT.
Repository level design
1. Created a business model containing the view and the GTT (mentioned above)
2. Created two SESSION variables "from_dt" and "to_dt" to be initialized by their respective init blocks. Each of the variable is initialized with a DATE column value (of type DATETIME) from a database lookup table. I have also set the option "Enable that variable to be set by any user" for both variables.
Query for these variables :
from_dt = select from_date from <table>
to_dt = select add_months(from_date,12) from <table>
Presentation level design
1. Using a text box, i display the default/initialized values of these variables like this -
Current business date:@{biServer.variables['NQ_SESSION.from_dt']} Future business dt:@{biServer.variables['NQ_SESSION.to_dt']}
Dates get displayed in YYYY-MM-DD 00:00:00 format
The text msg displays these default dates and allows the user to specift different date range for which i create prompts as shown below.
2. Using any random two columns of date type from the business model, i create two date dashboard prompts with labels "From Dt" and "To Dt".
i select Calender Controls for both; setting Default To = Report Defaults.
The Set Variable is set to Presentation variables - such that pv_from_dt maps to "From Dt" and pv_to_dt maps to "To Dt".
3. i create the report using the business model created above. In the report "Advanced Tab" => "Prefix" field i specify the following -
SET VARIABLE from_dt='@{pv_from_dt}',to_dt='@{pv_to_dt}';
Note : The logic here is to display the default dates and allow user to specify different date values which will be stored in presentation variables.
If the user does specify different "from dt" and "to dt" values, then using the presentation variables, i want to "write" back these new values to the corresponding session variables mentioned above.
If the user does not specify different date range, then the default/initialized dates must be considered.
I also display the default and new date values in the report title.
Back to Repository level design
To execute the stored procedure that will load the GTT before running the report I need to pass two date parameters to the stored procedure on basis of which it will fetch data, process and populate the GTT.
In the Connection Pool --> Connection Script Tab --> Execute before query, I wrote the below query using the repository variables FROM_DT and TO_DT to execute the procedure -
DECLARE
v_from_dt date;
v_to_dt date;
BEGIN
v_from_dt := VALUEOF(From_Dt);
v_to_dt := VALUEOF(To_Dt);
package_name1.package_body(v_from_dt,v_to_dt);
END;
Now when i try to run the report i get the following error :
[nQSError: 10058] A general error has occurred. [nQSError: 23006] The session variable, NQ_SESSION.to_dt, has no value definition. (HY000)..
Need help on this.
Is it possible to "write back" a new value to a session variable ?
Any other alternatives.
Thanks
Nusrat

Sandeep, I found a several topics where users describe saving values in DB through stored procedure or function. For example, [How to store OBIEE presentation level variable values in DB |http://forums.oracle.com/forums/thread.jspa?threadID=892006] I tried it and get an error
*10058. [NQODBC] [SQL_STATE: HY000] [nQSError: 10058] A general error has occurred. [nQSError: 17001] Oracle Error code: 14551, message: ORA-14551: cannot perform a DML operation inside a query ORA-06512*
It's not a BI error. This error are generated by Oracle DB. If I write next:
SELECT MyPLSQLFunction(p1,p2) FROM DUAL
I get the same error.
Oracle doesn't allow DML operations in SELECT.
Did you relalize this feature yourself? Where did I mistake?

System session variable USER

Hi,
i have setup-ed the action links and used the USER variable for the EBS secuirty context init block as this
EBS_RESP_ID
EBS_RESP_APPL_ID
EBS_SEC_GROUP_ID
EBS_RESP_NAME
EBS_USER_ID
EBS_EMPLOYEE_ID
USER
Now for the sso configuration in the RPD i need to use the USER variable again as per the document (section A.1.1 )http://docs.oracle.com/cd/E14571_01/bi.1111/e10543/legacy.htm#BABFJEJF
"To set up LDAP authentication:
Create an LDAP Server as follows:
Select Manage then Identity in the Oracle BI Administration Tool to launch the Security Manager.
Select Directory Servers from the left pane in Security Manager.
Right-click in the right pane in Security Manager and select New LDAP Server. The LDAP Server dialog is displayed.
Create the LDAP server by completing the fields.
Create an LDAP initialization block and associate it with an LDAP server. For more information. see "Creating Initialization Blocks" in Oracle Fusion Middleware Metadata Repository Builder's Guide for Oracle Business Intelligence Enterprise Edition.
Define a system variable named *USER* and map the USER variable to an LDAP attribute (uid or sAMAccountName)."
So how can i use the same user variable and assign it to LDAP init block as well the EBS security context init block.
can you provide your valuable inputs here.

Trying to move a list of form variables to session variables of the same name

I am trying to move a list of form variables to session variables of the same name and I am having a lot of trouble.
I have never had to post of this forum with a language question in all the 10 years I have been using ColdFusion. I was a qa Engineer @ Allaire/Macromedia back when it was going from one to the other. I have a pretty good grasp of the language.
I have software that runs off a list. The fieldnames are variable and stored off in an array. It's survey software that runs off a "meta file". In this example; I have the number of fields in the survey set to 12 in the "metafile". I have each field declared in that file in array Session.SurveyField[1] and the above loop works fine. I include this "metafile" at the start of the process.
I cfloop around a struct and it works wherever I have needed to use it; such as here - writing to the database for example;
<CFQUERY NAME="InsertRec" DATASOURCE="Survey">
INSERT into #variables.SurveyTableName#
(EntryTime
<cfloop from="1" to="#Session.NumberOfSurveyFields#" index="arrayindex">
,#Session.SurveyField[arrayindex]#
</cfloop>

   VALUES
    ('#EntryTime#'
<cfloop from="1" to="#Session.NumberOfSurveyFields#" index="arrayindex">
<cfset thisname = "Session." & Session.SurveyField[arrayindex]>
,'#evaluate(variables.thisname)#'
</cfloop>

</CFQUERY>
NOW HERE'S THE PROBLEM: I am running into trouble when trying to move the form variables to session variables of the same name. It is the only part of the software that I still need the datanames hard coded and that is a roadblock for me.
<cfloop from="1" to="#Session.NumberOfSurveyFields#" index="arrayindex">
<cfset thissessionfield = "Session." & Session.SurveyField[arrayindex]>
<cfset thisformfield = "Form." & Session.SurveyField[arrayindex]>
<cfset #thissessionfield# = #evaluate(thisformfield)#>
</cfloop>
I have tried it with or without the "evaluate"; same result. It doesn't give an error; it just ignores them (session variables look as such in the next page in the chain)
q01_name=
q02_acadtechorna=
q03_water=
q04_firstaid=
q05_cpr=
q06_lifeguard=
q07_aed=
q08_projadv=
q09_color=
q10_santaclaus=
q11_supervisor=
q12_supervisoropinion=
Note: they exist because I CFPARAM them in a loop like the above at the start of the procedure) - and this works just fine!
<cflock scope="Session" type="EXCLUSIVE" timeout="30">
<cfloop from="1" to="#Session.NumberOfSurveyFields#" index="arrayindex">
<cfset dataname = "Session." & Session.SurveyField[arrayindex]>
<cfparam name="#variables.dataname#" default="">
</cfloop>
</cflock>
I EVEN tried exploiting the Form.Fieldnames list using CFLoop over the list and the same sort of logic within and it still gives me nothing....
Here's the FORM.FIELDNAMES value
"Q01_NAME,Q02_ACADTECHORNA,Q03_WATER,Q04_FIRSTAID,Q05_CPR,Q06_LIFEGUARD,Q07_AED,Q08_PROJAD V,Q09_COLOR,
Q10_SANTACLAUS,Q11_SUPERVISOR,Q12_SUPERVISOROPINION"
Here's the logic; SAME RESULT - The session variables don't get set.
<cfoutput>
<cfloop list="#Form.FieldNames#" index="thisfield">

<cfscript>
thisSESSIONfield = "Session." & thisfield;
thisFORMfield = "Form." & thisfield;
#thisSESSIONfield# = #thisFORMfield#;
</cfscript>
</cfloop>
</cfoutput>
The CFPARAM in a loop with variable output name works just fine; so does the post (which I included above) as does the SQL Create, Param Form Variables, Param Session Variables, etc.
THIS even works for moving BLANK to each session variable, to zero them all out at the end of the process;
<cflock scope="Session" type="EXCLUSIVE" timeout="30">
<cfloop from="1" to="#Session.NumberOfSurveyFields#" index="arrayindex">
<cfset thislocalfield = Session.SurveyField[arrayindex]>
<cfscript>
thissessionfield = "Session." & thislocalfield;
</cfscript>
<cfset #thissessionfield# = "">
</cfloop>
</cflock>
Expanding on that code, you would think this would work, but it doesn't;
<cfloop from="1" to="#Session.NumberOfSurveyFields#" index="arrayindex">
<cfset thislocalfield = Session.SurveyField[arrayindex]>
<cfscript>
thissessionfield = "Session." & thislocalfield;
thisformfield = "Form." & thislocalfield;
</cfscript>


<cfoutput>
<cfset #thissessionfield# = "#evaluate(thisformfield)#">
</cfoutput>
</cfloop>
And see that debug code in the middle? To add insult to injury... When I uncomment that it shows me this. So it certainly looks like this should work....
Session.q01_name = "Me"
Session.q02_AcadTechORNA = "N/A"
Session.q03_Water = "Yes (certificate expired)"
Session.q04_FirstAid = "Yes (certificate is current)"
Session.q05_CPR = "No"
Session.q06_LifeGuard = "Yes (certificate expired)"
Session.q07_AED = "Yes (certificate expired)"
Session.q08_ProjAdv = "Yes (certificate expired)"
Session.q09_Color = "Gray"
Session.q10_SantaClaus = "Yes"
Session.q11_Supervisor = "Da Boss"
Session.q12_SupervisorOpinion = "Not a bad thing"
There must be some simpler way to do this. This way won't work against all odds even though it seems so much like it should.
So I end up having to hardcode it; still looking for an automated way to set these #@%$*@!## session variables over the list from the form variables of the same @#@!$#%$%# name. Do I sound frustrated???
No matter what I do, if I don't HARDCODE like this;
<cfset Session.q01_name = Form.q01_name>
<cfset Session.q02_AcadTechORNA = Form.q02_AcadTechORNA>
<cfset Session.q03_Water = Form.q03_Water>
<cfset Session.q04_FirstAid = Form.q04_FirstAid>
<cfset Session.q05_CPR = Form.q05_CPR>
<cfset Session.q06_LifeGuard = Form.q06_LifeGuard>
<cfset Session.q07_AED = Form.q07_AED>
<cfset Session.q08_ProjAdv = Form.q08_ProjAdv>
<cfset Session.q09_Color = Form.q09_Color>
<cfset Session.q10_SantaClaus = Form.q10_SantaClaus>
<cfset Session.q11_Supervisor = Form.q11_Supervisor>
<cfset Session.q12_SupervisorOpinion = Form.q12_SupervisorOpinion>
I always get this from my next page because the session variables are empty;
You must answer question 1.
You must answer question 2.
You must answer question 3.
You must answer question 4.
You must answer question 5.
You must answer question 6.
You must answer question 7.
You must answer question 8.
You must answer question 9.
You must answer question 10.
I tried duplicate as well, but I can not get the above to work...
Can anyone help me do this thing that one would think is simple????

I think if you use structure array syntax you should get the results you want.
<cfloop from="1" to="#Session.NumberOfSurveyFields#" index="arrayindex">
      <cfset session[Session.SurveyField[arrayindex]] = Form[Session.SurveyField[arrayindex]]>
</cfloop>
Or probably even easier.
<cfset session = duplicate(form)>

Compare data record to session variable

I am completely stumped. It should be easy.
I am trying to compare a field from a database to a sesssion variable on a JSP page and even though the fields print out the same when I call them in JSP, my "If" statement never gets activated.
Here's the last version of the code I tried:
String usernamev = UserSession.getValue("username").toString();
String custname = RS.getString("ORCUST");
if (usernamev.equals(custname))
userrole="Customer ";
I've also tried this:
String usernamev = UserSession.getValue("username").toString();
String custname = RS.getString("ORCUST").toString;
if (usernamev.equals(custname))
userrole="Customer ";
And I've also tried this:
if (RS.getString("ORCUST").equals(usernamev))
userrole= "Customer ";
And This:
And I've also tried this:
if (usernamev.equals(RS.getString("ORCUST")))
userrole= "Customer ";
When RILLI is the field I'm trying to compare this works:
if (usernamev.equals("RILLI"))
userrole= "Customer ";
Somehow my data type must be wrong but I can't figure out why. When I print out
<%=usernamev%>
and <%=RS.getString("ORCUST")%>
they show on my webpage as RILLI. I can also assign a constant value to userrole without a problem.
What the heck am I doing wrong?

I think limeybrit was on the right track and I hadn't trimmed because I got a no trim method error before because I hadn't converted session variable to a string.
When I used this:
String usernamev = UserSession.getValue("username").toString();
usernamev = usernamev.trim();
String custname = RS.getString("ORCUST").trim();
I think its working now. Thanks for help all.

Session variable getting reset when leaving dashboard

I have created a session variable with the 'Enable any user to set the value' option. I'm using the session variable as the default for a dashboard prompt. I'm able to set the variable with that dasboard prompt, and I can confirm that it is indeed getting set properly. So the interaction of the variable and the prompt seems to be in order.
After I make a selection from the dashboard prompt, as long as I stay in the dashboard, the session variable stays set to my selection. I can move from page to page and everything is fine. The selection stays put as I have set it. However, the moment I leave the dashboard, the session variable is reinitialized back to its default value as specified by the SQL in its initialization block. I can go from dashboard to catalog and back to dashboard - boom, it's back to the default. My selection has been replaced. ???
And here's an odd thing: I can look in the query log and see the initialization block code getting run when I log in. So far, so good. I can run the dashboard, make a prompt selection, and see the query log updated just fine. Still OK. BUT... when I switch from dashboard to catalog and back to dashboard, the value of the session variable is reset (I see the default month in my analysis and as the prompt default upon redisplay of the dashboard page), but there's no indication in the query log that the initialization block SQL ran again. The last SQL in the query log still shows my "selected" value in the SQL. The dashboard page is showing the "default", while the last entry in the query log shows the "selected".
Can anyone else confirm this odd behavior? And is there a reason that a session variable should not retain its value throughout the session? I've always viewed session variables as little buckets of single-cell data whose contents are consistent and static for the duration of a session, unless manually changed by a dashboard prompt. If the behavior that I'm seeing is both replicatable and expected, it would appear that my understanding is flawed.
Running 11.1.1.7.0 on Windows Server 2008. Same behavior is occurring in both Firefox 21 and IE 9.

Thank you for your answer MK,
I try to write a SQL in my prompt but not work for me:
-In default selection I choose SQL Results and I type: Year(Current_date) and save my prompt and I don't see any value in my dashboardpage, if I click in prompt I can see all members of my year dimension but by default is empty.
I modify the other solution: I have 1hour refresh time and I change for 1 minute, but doesn't work.
the default initializer is in RPD (variable year that belongs to BI_Year Block) and I have written 2009.

Javacard and session variables

Hello,
I'm trying to find a reasonable Javacard technique to handle "session variables" that must be kept between successive APDUs, but must be re-initialized on each card reset (and/or each time the application is selected); e.g. currently selected file, currently selected record, current session key, has the user PIN been verified...
Such variables are best held in RAM, since changing permanent (EEPROM or Flash) variables is so slow (and in the long run limiting the operational life of the card).
Examples in the Java Card Kit 2.2.2 (e.g. JavaPurseCrypto.java) manipulate session variables in the following way:
1) The programmers group session variables of basic type (Short, Byte, Boolean) according to type, and map each such variable at an explicit index of a vector (one per basic type used as session variable).
2) At install() time, each such vector, and each vector session variable, is explicitly allocated as a transient object, and this object is stored in a field of the application (in permanent memory), where it remains across resets.
3) Each use of a session variable of basic type is explicitly translated by the programmer into using the appropriately numbered element of the appropriate vector.
4) Vector session variables require no further syntactic juggling, but eat up an object descriptor worth of permanent data memory (EEPROM or Flash), and a function call + object affectation worth of applet-storage memory (EEPROM, Flash or ROM).
The preparatory phase goes:
public class MyApp extends Applet {
// transientShorts array indices
    final static byte      TN_IX = 0;
    final static byte      NEW_BALANCE_IX=(byte)TN_IX+1;
    final static byte      CURRENT_BALANCE_IX=(byte)NEW_BALANCE_IX+1;
    final static byte      AMOUNT_IX=(byte)CURRENT_BALANCE_IX+1;
    final static byte   TRANSACTION_TYPE_IX=(byte)AMOUNT_IX+1;
    final static byte     SELECTED_FILE_IX=(byte)TRANSACTION_TYPE_IX+1;
    final static byte   NUM_TRANSIENT_SHORTS=(byte)SELECTED_FILE_IX+1;
// transientBools array indices
    final static byte      TRANSACTION_INITIALIZED=0;
    final static byte      UPDATE_INITIALIZED=(byte)TRANSACTION_INITIALIZED+1;
    final static byte   NUM_TRANSIENT_BOOLS=(byte)UPDATE_INITIALIZED+1;
// remanent variables holding reference for transient variables
    private short[]     transientShorts;
    private boolean[]   transientBools;
    private byte[]      CAD_ID_array;
    private byte[]      byteArray8; // Signature work array
// install method
    public static void install( byte[] bArray, short bOffset, byte bLength ) {
         //Create transient objects.
        transientShorts = JCSystem.makeTransientShortArray( NUM_TRANSIENT_SHORTS,
            JCSystem.CLEAR_ON_DESELECT);
        transientBools = JCSystem.makeTransientBooleanArray( NUM_TRANSIENT_BOOLS,
            JCSystem.CLEAR_ON_DESELECT);
        CAD_ID_array = JCSystem.makeTransientByteArray( (short)4,
            JCSystem.CLEAR_ON_DESELECT);
        byteArray8 = JCSystem.makeTransientByteArray( (short)8,
            JCSystem.CLEAR_ON_DESELECT);
(..)and when it's time for usage, things go:
    if (transientShorts[SELECTED_FILE_IX] == (short)0)
        transientShorts[SELECTED_FILE_IX] == fid;
    transientBools[UPDATE_INITIALIZED] =
        sig.verify(MAC_buffer, (short)0, (short)10,
            byteArray8, START, SIGNATURE_LENGTH);I find this
a) Verbose and complex.
b) Error-prone: there is nothing to prevent the accidental use of transientShorts[UPDATE_INITIALIZED].
c) Wastefull of memory: each use of a basic-type state variable wastes some code; each vector state variable wastes an object-descriptor worth of permanent data memory, and code for its allocation.
d) Slow at runtime: each use of a "session variable", especially of a basic type, goes thru method invocation(s) which end up painfully slow (at least on some cards), to the point that for repeated uses, one often attain a nice speedup by caching a session variable, and/or transientShorts and the like, into local variables.
As an aside, I don't get if the true allocation of RAM occurs at install time (implying non-selected applications eat up RAM), or at application selection (implying hidden extra overhead).
I dream of an equivalent for the C idiom "struct of state variables". Are these issues discussed, in a Sun manual, or elsewhere? Is there a better way?
Other desperate questions: does a C compiler that output Javacard bytecode make sense/exists? Or a usable Javacard bytecode assembler?
Francois Grieu

Interesting post.
I don't have a solution to your problem, but caching the session variables arrays in local variable arrays is a good start. This should be only done when the applet is in context, e.g. selected or accessed through the shareable interface. This values should be written back to EEPROM at e.g. deselect or some other important point of time. Do you run into problems if a tear happens? I don't think so since the session variables should be transactional, and a defined point will commit a transaction.
Analyzing the bytecode is a good idea. I know of a view in JCOP Tools (Eclipse plugin) where you can analyze the bytecode and optimize it to your needs.

Session variable and initialization block issues

We are using OBIEE 10.1.3.3 and utilizes built in security features. (No LDAP or other single sign on). The user or group names are not stored in any external table. I have a need to supplement Group info of the user to the usage tracking we implemented recently as the NQ_LOGIN_GROUP.RESP column contains username instead of group name. So I created a session variable and associated with a new initialization block and also had a junk default value set to the variable. In the initialization block, I wrote the following query and as a result it inserted correct values into the table when the TEST button was clicked from the initialization block form.
insert into stra_login_data (username, groupname, login_time) values ('VALUEOF(NQ_SESSION.USER)', 'VALUEOF(NQ_SESSION.GROUP)', SYSDATE)
My intention is to make this execute whenever any user logs on. The nqserver.log reports the following error and it doesn?t insert values into the table.
[nQSError: 13011] Query for Initialization Block 'SET_USER_LOGIN_BLOCK' has failed.
[nQSError: 23006] The session variable, NQ_SESSION.USER, has no value definition.
[nQSError: 13011] Query for Initialization Block 'SET_USER_LOGIN_BLOCK' has failed.
[nQSError: 23006] The session variable, NQ_SESSION.GROUP, has no value definition.
When I changed the insert statement as below, this does get populated whenever someone logs in. But I need the values of GROUP associated with the user as defined in the repository.
insert into stra_login_data (username, groupname, login_time) values ('TEST_USER', TEST_GROUP', SYSDATE)
Could someone help me out! As I mentioned above, I need the GROUP info into the usage tracking. So, if there is another successful approach, could you please share?
Thank you
Amin

Hi Amin,
See [this thread|http://forums.oracle.com/forums/thread.jspa?messageID=3376946&#3376946]. You can't use the GROUP session variable in an Init Block unless it has been seeded from an Init Block first. There isn't an easy solution for what you want, but here are some options:
1) Create a copy of your User => Groups assignments in your RPD in an table so you can use it in your Usage Tracking Subject Area. But this means you will have to replicate the changes in two places so it's not a good solution.
2) As the GROUP session variable is populated when you login you could theoretically use it a Dashboard and pass it a parameter to write the value to the database. But as I am not sure how can you make fire only once when the user logins it sounds like a bad idea.
3) Move your User => Groups assignments from your RPD to a DB table. Use OBIEE Write Back or something like Oracle APEX to maintain them.
I think 3) is the best solution to be honest.

Direct database request and session variable value

Hi,
I have a problem by doing the following : idea is to have report with a list of all tables in user schema (which are not all in repository physical layer).
By clicking on the name of any, should bring answer report which is done as direct database request doing basically select * from table_clicked (this will be basically the same table with sufix _err holding error rows).
What I'm trying to do is having some kind report for error rows which can be in different tables in my database. So i had in mind to construct name of table i need , and pass it to database request through session variable. Am i doing right by doing direct database request like this :
select * from 'VALUEOF(NQ_SESSION.TestVar2)'
Is there another easyer way of doing this? I know this can be done by gourl by passing parameters but not sure how when i can't filter columns in direct database request (this can be different tables with different names of columns). I hope i didn't complicated this too much.
Thnx in adwance

Hi,
I know this is a hack, and would be much more easy to create one table with dimension and measures, but this is intended to be used with code generator, which can produce different error tables with different column names in different time: It is not conviniet for somebody to add them to repository every 5 minutes. For example : i run my workflow and for first run I have errors in table1(let us say customer table with 30 columns) and if click on the table name in some answer report, i want to see all the bad records in the table. Tomorrow after the run, there are bad records in table1 and in table2 (lets say products) so I would have choice to pick table 1 or table2 and see al the bad records in any of these tables. This means that I can not now which tables will I have tomorrow, and as it is generic, I can manually add some tables in my model, and would have to add err table also as a possibility to have error rows?
I saw post saying that you can pass parameter value by using go url functionality, by modifying configinstance file, but didn't suceed - http://gerardnico.com/wiki/dat/obiee/logical_sql/obiee_session_variable_go_url . Maybe some mistake or any better solution? I created session variable TestVar2, also modified instanceconfig.xml by adding this before </ServerInstance>
<ParamList>
<Param name="NQ_SESSION.TestVar2" source="url" nameInSource="SETVAR"/>
</ParamList>
and used go url in column formula : ''||"Physical Targets"."Physical Table"||''
Can I use @1 for using first column value?
Thnx

How to pass session variable value with GO URL to override session value

Hi Gurus,
We have below requirement.Please help us at the earliest.
How to pass session variable value with GO URL to override session value. ( It is not working after making changes to authentication xml file session init block creation as explained by oracle (Bug No14372679 : which they claim it is fixed in 1.7 version Ref No :Bug 14372679 : REQUEST VARIABLE NOT OVERRIDING SESSION VARIABLE RUNNING THRU A GO URL )
Please provide step by step solution.No vague answers.
I followed below steps mentioned.
RPD:
****-> Created a session variable called STATUS
-> Create Session Init block called Init_Status with SQL
select 'ACTIVE' from dual;
-> Assigned the session variable STATUS to Init block Init_Status
authenticationschemas.xml:
Added
<RequestVariable source="url" type="informational"
nameInSource="RE_CODE" biVariableName="NQ_SESSION.STATUS"/>
Report
Edit column "Contract Status" and added session variable as
VALUEOF(NQ_SESSION.STATUS)
URL:
http://localhost:9704/analytics/saw.dll?PortalGo&Action=prompt&path=%2Fshared%2FQAV%2FTest_Report_By%20Contract%20Status&RE_CODE='EXPIRED'
Issue:
When I run the URL above with parameter EXPIRED, the report still shows for ACTIVE only. The URL is not making any difference with report.
Report is picking the default value from RPD session variable init query.
could you please let me know if I am missing something.

Displaying Session Variable on Dashboard & creating presentation variable

Hi.
I read a bit more on mysupport and it seems that :xdo_user_roles somehow displayes all kind of roles not the ones that the user acutally belongs to.
Now I wonder if I can use NQ_SESSION.GROUP in the BI Publisher data model.
(A)I figured that I can create a "list of values" in the data model and there I can select Oracle BI EE as a data source. maybe in the repository I can create a column that holds the nqsession_groups that I then use in the data model sql. assuming I can use a list of values in the sql.
(B) or I pass it as a parameter to the report/data modell just like a normal dropdownlist parameter (presentation variable)
Then I tried adding a text item on the dashboard with
@{biServer.variables[NQ_SESSION.USER.displayName]}
or
Session Variable My Year : @{biServer.VARIABLES['v_USER_GROUPS']} *
BUT none of them actually display any variables. :/
*this one I created in the repository and has the correct values

When I remove "authenticated-role" from the BIConsumer Role in EM and visit my dashboard again I can see that the user is ONLY in role "AuthenticatedUser" now I wonder why this is the only one, I created a custom role in EM and added the user to that one but it does not show :/
