Session Variables Disappearing

This issue of disappearing session variables keeps coming up
again and again. I am reading about session variables work from
Adobe site and it say this
Click
Here
Session variables have the following
traits:
In order for session variables to
work, the visitor's browser must be set to accept cookies.
The pages for
the site all must be located within a single directory on the web
server.
Information stored in session
variables is site visitor specific. Different site visitors cannot
access each other's session variable information.
My question is this (about the highlighted). since my
application.cfm is located in the root directory and the session
variables are set from different directories under the root, will
this be the problem? Users login into the site from the members
directory and the sessions for that user are set after successful
login. when the user tries any other link from a different
directory the session disappears. Is this a recurring problem with
CFMX (6.1)or am I the only one experiencing this. I wish someone
from ADOBE should also respond to this.

The session variables are good for the entire application.
And the application is defined as any file at the same level or
beneath the application.cfm. If you are trying to access files that
do not fall under or at the same level as application.cfm then your
session variables would be invalid.

Please Help Session variables disappear

Hi. I am having issues with the developer's version of CF MX
7. I recently set up the developer's version on a test server, and
moved over code from a properly working site using MX 6. I have an
application.cfm file set will the correct <cfapplication> tag
attributes, and the session management is set in the CF admin. When
working on MX 6 the session variables I set were working. Now using
MX 7 none of my sessions are holding. When I first login the
sessions exist, if I click any other page, the variables disappear.
Again, this does not happen on MX 6.
Please help!
Thanks,
jlg

Double-check your sessiontimemout
Try setting up a simple test application using something
similar to the example at

Use of session variables disappeared

Hi - I have a really old CF site that has worked perfectly all these years.
Sometime over the past 7 days, my all of my session variables have ceased to work.
These session variables appear on the pages where I set them up, but the minute I transfer to a new page, they are completely gone. They do not appear in the debug information at all.
I think that there has been some change in CF Server 8, but my system administrator says that he did not change any settings. (If he had, what would it be? I don't have admin access.)
Like I said, they worked perfectly until very recently and luckily, I don't use a load of them.
If push comes to shove, I can use cookies, but I really don't want to sit through an evening of debugging.
What do you think went wrong?
Help!

Well - thank U. My system admin said he did not touch a thing, and furthermore, my test works well for him.
Here is my test:
http://www.littleviews.com/test/test_1.cfm
Page 2 should fail, or at least it does for me (I live on the East Coast in Weehawken), but it does not to him (the Milwaukee/Waukesha area in Wisconsin)

Disappearing session variables

Using xppro & cf9--I have session variables that I created on page A, but when I move to page B the session variables disappear. I can't figure out what I'm doing wrong....can't even firgure out where to look, although I've gone through page B to see where I might accidentally invalidate the session variables. The CFID is the same for both pages. Any thoughts?

Seeing the code would help.
Here are some things to check.
1. What session related settings are setup in the CF adminstrator?

Problem: variable disappears from Session after cfquery

I have the following problem in my CFML script. I added a
variable MyVariable in Session variable. Then I call
<cfquery>. When the <cfquery> finishes, the variable
MyVariable does not exist in the Session!

In fact, name of the MyVariable was loginresult. The sequence
was approximately as the following:
<cfset Session["loginresult"] = 0>
<cfif Session["loginresult"] eq 0>
<cfquery ...>
<cfif Session["loginresult"] eq 0>
</cfif>
</cfquery>
</cfif>
The problem happened on SECOND line "<cfif
Session["loginresult"] eq 0>" - one that follows
<cfquery>. The line produces exception :
coldfusion.runtime.UndefinedElementException: Element
loginresult is undefined in a Java object of type class
coldfusion.runtime.MemorySessionScope referenced as
What is most misterious, I have teh same CFM code on two
computers (ColdFusion MX7 on both). One of them the code works OK;
on other it causes the problem I described.

Session Variables Randomly Lost between Pages

My web page uses a session to keep track of who logged in.
What I noticed is that the session variables stored appears and
disappears randomly on different pages. The wierd thing is that my
code is very simple.
For the life of me I can not figure this out....

I go through a hosting company and do not expect them to do
any load balancing.
What are sticky sessions?
The cflocation tag also has the addtoken="yes" to it now and
symptoms persist.
I tested the case with
sessiontimeout=#CreateTimeSpan(0,2,0,0)# instead of the
sessiontimeout=#CreateTimeSpan(0,0,120,0)# and symptoms still
persist.
Any other suggestions? I think I ran into a wall
here....

Alternate method to writing filter for recordset using session variable

I'm not sure if this can be done. I have a user page which I'd like to return database info based upon a userid entered on another page. So far, the session variable (userid) is captured on the user page however it is supposed to return the user's name rather than displaying the session variable.
My problem is this. Within dreamweaver, I am able to create recordsets however I cannot create a filter. The connection works. At this point, I am searching for a workaround where I can tie in the session variable to recordsets. I should make mention that whenever I update the sql statement using the recordset widget, my recordset disappears. ? At any rate, heres a sample of the code sans connection strings, etc.
<%
Dim Recordset1
Dim Recordset1_cmd
Dim Recordset1_numRows
Set Recordset1_cmd = Server.CreateObject ("ADODB.Command")
Recordset1_cmd.ActiveConnection = MM_newuniversity1_STRING
Recordset1_cmd.CommandText = "SELECT name FROM table WHERE userid = '" & Session("userid_my") & "'"
Recordset1_cmd.Prepared = true
Set Recordset1 = Recordset1_cmd.Execute
Recordset1_numRows = 0
%>
On the user page, I have a 'Welcome' and the following code
{Request.userid_my}
Any suggestions? I'm afraid I'm a newbie to asp within dreamweaver cs3.

>When I insert request.userid_my code it returns the session variable
AFAIK, session variables are not part of the request object - so I do not understand why you are referencing them this way. I would use the standard reference method : Welcome <%Response.Write(Session("username"))%>
>when I insert the recordset associated with 'name' I get an Adobe End of file error. ?
Sounds like a possible problem with your installation. You may need to try reinstalling DW. How are you "inserting" this recordset and when does the error occur?
Regarding your next post...
>select name from table_name where userid = '" & namemy & "'"
>The statement consistently returns a 'quoted string not properly terminated' error.....
The select statement you quoted is obviously not complete. If you are refering to the select in your OP:
Recordset1_cmd.CommandText = "SELECT name FROM table WHERE userid = '" & Session("userid_my") & "'"
I see nothing wrong with that syntax and the string appears to be terminated correctly. If there is a different statement causing the error, please post the entire line and include a line above and below.

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?

Session variable size limitation (LV Webservices)

Hi community,
I read couple dozen email addresses from an XML and trying to write them into a session variable. The email addresses are comma separated and have a total string length of about 1100 characters. When I try to write it into a session variable LabVIEW drops an error message (-67158).
It is very clearly related to the size of the string as if use lets say only 200 characters I dont receive the error message.
How can I get rid of this limitation?
Thanks!

I am writing a general purpose webpage where I need email notifications. I have the workaround ready (before I send out the emails I dont read the emails from a session, but using the userID stored in the session to read the email from the xml). But generally having this limitation is annoying and unnecessary as normally you easily can store 100kB in one session. (probably even more, but that was the max I have ever did)

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)>

Can we use session variables in BI publisher's Data Model SQL Query?

Hi Experts,
We need to implement Data level security in BI Publisher 11g.
In OBIEE we do so by using session variables, so just wanted to ask if we can use the same session variables in BI Publisher as well
ie can we include the where clause in the Data Models SQL Query like
Where ORG_ID = @{biServer.variables['NQ_SESSION.INV_ORG']}
Let me know your views on this.
PS: We are implementing EBS r12 security in BI Publisher.
Thanks

Read this -> OBIEE 11g: Error: "[nQSError: 23006] The session variable, NQ_SESSION.LAN_INT, has no value definition." when Creating a SQL Query using the session variable NQ_SESSION.LAN_INT in BI Publisher [ID 1511676.1]

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.

Urgent help required...for replacing JSP session variables

I am trying to enhance the performance of a j2ee based webapp which use session variables to store the data...
Is there any alternative for session variables..The project is based on j2ee-Struts frame work..But the amount of code maintainance should be minimum ....so i can't create beanforms for all these data...
Is there any XML based methods available...??

ok... thanks... i created a fla file and inthe action script

Passing attribute value in session variable

Hi All
I need to store one field value from my SIM form as a session variable and pass them to the next page along with my session, using some jscript stuff or else. Does this make sense?
If it is possible or anyone have any prior experience please reply.
Thanks in advance

We have tested a code-snippet that 'gets' attribute-values from the session:
<invoke name='getAttribute'>
    <invoke name='getHttpSession'>
        <ref>:display.state</ref>
    </invoke>
    <s>attribute_name</s>
</invoke>You can try 'setAttribute' in the similar way.
Thanks,
Adi
