Proxy plugin - Debug parameter values

Up until a few months ago the proxy plugin documentation for WLS 8.1 included multiple values that the Debug parameter could be set to (e.g ALL to see just about everything, ones to see just headers etc). Now it only seems to have True|False. http://e-docs.bea.com/wls/docs81/plugins/plugin_params.html#1154491
Is there a reason this was changed? The old way was much more flexibile.
Has this been changed for the latest SP?
I am holding out some hope that maybe the documentation is incorrect.... Debug=ALL still works for 8.1 sp4

all the options seem to be there and working.
we are using DEBUG=ERR, since ALL crashes linux when the log grows to 2GB!

Dear elving,
I am facing the problem to configure reverse proxy plugin.From webserver 6.1 sp8 I want to serve pages that are on application server
our evirnonment

only webserver is visible to internet & appserver is in intranet environment.
no one will give hit directly to appserver.

ReportDocument.ExportToStream raises "Missing Parameter Values" exception

Hi,
I have a web app built using VS 2008 which runs many reports developed in CR 2008. Most of these reports take parameters and many have embedded subreports. Many of the reports can either be viewed directly or e-mailed. For the latter, I use ReportDocument.ExportToStream(ExportFormatType.PortableDocFormat) to export a PDF file which then gets attached to the e-mail.
One set of reports works fine when viewed directly, but raises a "Missing Parameter Values" exception when I try to generate the PDF. All the other reports, seemingly similar in most respects, including the number and type of parameters, work fine when calling ExportToStream.
Here is the really strange part: the exception is spurious. I wrapped the whole thing in a try/catch block to better examine the exception, hoping to find which parameter value is actually missing. I could not identify the missing parameter value, but once I handled the exception, the report runs fine and converts to PDF.
Any hints as to what could be causing this problem? It seems like a really bad hack to solve the problem using a try/catch in this way.
Thanks.
Dan

Thanks for the quick response. Your code was very instructive, but did not help yet. Here is what I have:
(This response is too long for a single post, so I will split it and finish in the next post.)
ReportDocument rptDoc = new ReportDocument();
rptDoc.Load(strReportSourceFolder + strReportName + ".rpt");
rptDoc.SetParameterValue("ClientID", lngKeyFieldID);
rptDoc.SetParameterValue("Role", "Client");
This is followed by an amazing chunk of code, provided to me by a guy at SAP Tech Support, who said it was necessary to pass database credentials programatically. It iterates the tables in the ReportDocument and individually sets the LogonInfo. (I say "amazing" because it astounds me you have to jump through such hoops for something that should be routine and easy.) The commented lines are just to help in debugging.
ConnectionInfo conn = new ConnectionInfo();
conn.ServerName = "myServer";
conn.DatabaseName = "myDB";
conn.UserID = "myUserID";
conn.Password = "myPassword";
Tables tables = rptDoc.Database.Tables;
foreach (Table table in tables)
//string str= table.TestConnectivity().ToString());
TableLogOnInfo tableLogonInfo = table.LogOnInfo;
tableLogonInfo.ConnectionInfo = conn;
table.ApplyLogOnInfo(tableLogonInfo);
//table.Location = table.Location;
This is followed by the viewer stuff:
CrystalReportViewer1.DisplayGroupTree = false;
CrystalReportViewer1.DisplayToolbar = true;
CrystalReportViewer1.HasToggleGroupTreeButton = false;
CrystalReportViewer1.HasToggleParameterPanelButton = false;
CrystalReportViewer1.Page.Title = strReportName;
CrystalReportViewer1.ReportSource = rptDoc;
Up to here, it works fine, displaying the report. If the report is also to be e-mailed, the following is executed:
if (bEmail)
// export to PDF, then mail that
SmtpClient client = new SmtpClient();
MailAddress from = new MailAddress(ConfigurationManager.AppSettings["ReportMailFrom"].ToString());
MailMessage message = new MailMessage();
message.From = from;
message.SubjectEncoding = System.Text.Encoding.UTF8;
message.Subject = "E-mail BackOffice report: " + strReportName;
try
    foreach(ParameterField field in rptDoc.ParameterFields)
      Logger.LogEvent("test", "", field.ToString(), "Trace", null, true, true);
      Logger.LogEvent("test", "", "Name: " + field.Name, "Trace", null, false, false);
      Logger.LogEvent("test", "", "PromptText: " + field.PromptText, "Trace", null, false, false);
      Logger.LogEvent("test", "", "IsOptionalPrompt: " + field.IsOptionalPrompt, "Trace", null, false, false);
    MemoryStream memStream = (MemoryStream)rptDoc.ExportToStream(ExportFormatType.PortableDocFormat);
    Attachment data = new Attachment(memStream, MediaTypeNames.Application.Pdf);
    ContentDisposition disposition = data.ContentDisposition;
    disposition.CreationDate = DateTime.Now;
    disposition.ModificationDate = DateTime.Now;
    disposition.FileName = strReportName + ".pdf";
    disposition.DispositionType = DispositionTypeNames.Attachment;
    message.Attachments.Add(data);
catch (Exception ex)
    Logger.LogEvent("error", "Page_Load", strReportName + " Exception: " + ex.Message, "Trace", null, true, true);
// ... do the rest of the stuff to create & send the e-mail
(The rest of this message will be in the following post. Sorry it is so long.)

CrystalReportViewer: "Missing parameter values with implemented error event

I'm using the CrystalReportViewer in APS.net (C#), and try to display a report in it.
I've implemented the error event of the viewer to show the user a different error message than the viewer itself does.
         this.CrystalReportViewer.Error += new CrystalDecisions.Web.ErrorEventHandler(CrystalReportViewer_Error);
      protected void CrystalReportViewer_Error(object source, CrystalDecisions.Web.ErrorEventArgs e)
         var msg = "Error in CrystalReportViewer\r\n{0}".FormatInvariant(e.ErrorMessage);
         throw new InvalidOperationException(msg);
But.... Now if I want to show a report that has parameters in it, the parameter page does not appear before the report itself. How can I make my code work (without removing the implementation of the error event), so the viewer first shows the parameter page, before showing the actual report?

And in the Page_Load method:
this.CrystalReportViewer.Error += new CrystalDecisions.Web.ErrorEventHandler(CrystalReportViewer_Error);
I've done this so i can show my own error page to the user of the website. Otherwise the CRViewer shows his own error, and I do not want the user of the website to see this 'technical' error.
So i've implemented the CrystalReportViewer.Error method:
protected void CrystalReportViewer_Error(object source, CrystalDecisions.Web.ErrorEventArgs e)
   // Missing parameter values.
   var discardToShowParameterPrompt = (e.ErrorMessage.ToUpperInvariant() == "Missing parameter values.".ToUpperInvariant())
     || (e.ErrorMessage.ToUpperInvariant() == "Ontbrekende parameterwaarden.".ToUpperInvariant());
   if (discardToShowParameterPrompt)
      _Log.Debug("The parameter screen should be displayed now.");
   else
      var msg = "Error in CrystalReportViewer: {0}".FormatInvariant(e.ErrorMessage);
      throw new InvalidOperationException(msg);
If I load a report with no params in the report, the page shows immediately the report.
If I load a report with params in the report, the params page is shown, the user can enter the param values, and after pressing OK, the report is shown.
If an error occurs (for example the report cannot connect to the database), the viewer does NOT show the error (because i've implemented the _error event) but my code throws an InvalidOperationException, and this is handled by code so the error is logged to a file, and the user gets a user friendly message on the website.
If i do not implement the _error event, the user will see the technical error in the crystal reports viewer.
If I comment out the code where I'm looking for the string "Missing parameter values." (or "Ontbrekende parameterwaarden") the parameter page will not be shown, and an error will be thrown by the Crystal Reports viewer.
If I put e.handled = true in the _error event, and there is an error (for example the database cannot be found), no error will be thrown, and there is nothing to see in the viewer.
So for now the only way to get the params page is to implement the _error event the way i've done in the above code, checking the error message on a string value.

WebLogic proxy plugin: getPooledConn: No more connections in the pool

Hi,
We have weblogic proxy plugin installed in Sun One web server. but frequently we are getting following errors in proxy log:
<1670612410085901> attempt #0 out of a max of 5
<1670612410085901> Trying a pooled connection for '<IP>/<port>/<port>'
<1670612410085901> getPooledConn: No more connections in the pool for Host [<IP>] Port[<port>] SecurePort[<port>]
Can anybody please tell how this proxy plugin manages connection pools? I don't find any minimum / maximum number of conection to mention anywhere or how exactly it works?

Try increasing the "AcceptBackLog" settings on the weblogic server and then verify for any changed behavior.
Raise the Accept Backlog value from the default by 25 percent. Continue increasing the value by 25 percent until the messages cease to appear.

IP address lost in Weblogic proxy plugin

          Hi,
          We have 4 web servers that forward requests for jsps to 10 weblogic instances
          working in a cluster. The web servers have IPlanet with weblogic proxy plugin.
          One of the jsps has logic to retrieve the client's IP address and then return
          the name of the country to which the IP address belongs. But since the jsp always
          receives requests from one of the 4 web servers on the same LAN, it gets only
          the internal IP address of the web server and returns no country code. To retrieve
          the IP address of the caller in the jsp, I'm using
          ipAddress = request.getRemoteAddr();
          How can I make my jsp know the actual source IP address of the client (i.e the
          end user)?
          Any help would be appreciated.

Bug while using string parameter values in postgresql query

I have the following query for the postgresql database:

WHERE
$P!{mysortfield} LIKE '$P!{searchvalue}' || '%']]></queryString>
That is I try to select only the records where the field which is
selected by user as report parameter ($P{mysortfield}) contains data
starting with the text entered by user as a report parameter
($P{searchvalue}).
When I try to run the report in iReport with active connection to the
database the report is generated as expected.
But when I try to run the report from Sentinel Log Manager I get the
following error: "java.lang.String cannot be cast to
net.sf.jasperreports.engine.JRValueParameter".
After several detailed debug sessions I finally came into a conclusion
that this error is related to the use of parameter values (
$P!{mysortfield} and $P!{searchvalue} ).
I even tried using the following WHERE clause (which emulates the
queries as used in standart reports (especially at VendorProduct related
SQL queries ) with no success:
Code:
WHERE
($P{mysortfield} = 'evt_src_mgr_name' AND evt_src_mgr_name LIKE ($P{searchvalue} || '%')) OR
($P{mysortfield} = 'evt_src_collector_name' AND evt_src_collector_name LIKE ($P{searchvalue} || '%')) OR
($P{mysortfield} = 'evt_src_grp_name' AND evt_src_grp_name LIKE ($P{searchvalue} || '%')) OR
($P{mysortfield} = 'evt_src_name' AND evt_src_name LIKE ($P{searchvalue} || '%'))
Any suggestions?

Thank you for the suggestions:
While trying to implement your suggestions I realized that there was a
error at the parameter name I used inside the where clause (it should be
$P{searchfield}).
Here are my results:
Code:
vt_src_mgr_name LIKE '%' || '%'
worked as expected.
Code:
$P{searchfield} LIKE '%' || '%'
produced PDF but wrong output.
Code:
$P!{searchfield} LIKE '%' || '%'
resulted with the error "java.lang.String cannot be cast to
net.sf.jasperreports.engine.JRValueParameter" and no PDF.
Then I tried the following where clause which resulted in exactly as
expected PDF:
Code:
WHERE
($P{searchfield} = 'evt_src_mgr_name' AND evt_src_mgr_name LIKE ($P{searchvalue} || '%')) OR
($P{searchfield} = 'evt_src_collector_name' AND evt_src_collector_name LIKE ($P{searchvalue} || '%')) OR
($P{searchfield} = 'evt_src_grp_name' AND evt_src_grp_name LIKE ($P{searchvalue} || '%')) OR
($P{searchfield} = 'evt_src_name' AND evt_src_name LIKE ($P{searchvalue} || '%'))
As a summary:
* The query which works in iRepord do not work in Sentinel Log
Manager.
* I found a workaround for my case.
* I did not checked, but the reports provided in Sentinel RD which use
the same technique for VendorProduct parameter (i.e. the reports with
query string containing
Code:
LIKE ($P{VendorProduct} || '%')
will most probably not work as expected IF Sentinel RD uses the same
code as Sentinel Log Manager.

Weblogic proxy plugin closes keep-alive connections to clients randomly

In short we have following arhitecture:
clients ---> wl proxy plugin 1 ----> weblogic 1
clients ---> wl proxy plugin 2 ----> weblogic 2
Beacuse of the application/installation specific requirements, we are not using failover, one wl proxy always forwards requests to one weblogic (simple configuration).
Application is TR-069 protocol based (SOAP over HTTP) so it very much relays on persistence TCP connections (Connection: keep-alive). This TCP persistence has to work correctly in order that TR-069 messages are exchanged in required order, otherwise we have a error on application layer.
Here and there we've noticed applications errors which suggest that we have some problems in TCP connection between the client and the weblogic server. After sniffing, we've noticed that weblogic proxy plugin (Apache) randomly, or because of some other reason we do not know, decides to close TCP connection to client, even app on weblogic did not request so ???
As a result, client opens new connection to the server with new TR-069 session and it gets bounced beacuse it allready has one open on weblogic server.
We've sniffed, traced everything we could, we were searching for patterns in time, etc... but we can not find the reason why proxy plugin decides to close the connection to the client (not to the weblogic server).
Trace (replaced sensitive information):

!!!! Now it closes the TCP connection and inserts "Connection: close" HTTP header !!!
WL proxy plugin conf params are:
WebLogicCluster $IP$:$PORT$
DynamicServerList OFF
KeepAliveTimeout 90
MaxKeepAliveRequests 0
KeepAliveSecs 55
Apache worker configuration is:
<IfModule mpm_worker_module>

LockFile var/run/accept-worker.lock
StartServers 2
MinSpareThreads 25
MaxSpareThreads 75
ThreadLimit 200
ThreadsPerChild 200
MaxClients 2000
MaxRequestsPerChild 0
AcceptMutex pthread
</IfModule>
Why weblogic proxy plugin ignores Keep-alive directive and decides to close connection to the client by itself?
Any help?

If a WebLogic Server instance listed in either the WebLogicCluster parameter or a dynamic cluster list returned from WebLogic Server fails, the failed server is marked as "bad" and the plug-in attempts to connect to the next server in the list.
MaxSkipTime sets the amount of time after which the plug-in will retry the server marked as "bad." The plug-in attempts to connect to a new server in the list each time a unique request is received (that is, a request without a cookie).
Note: The MaxSkips parameter has been deprecated as the MaxSkipTime parameter.

You said the problem arises under significant load. Maybe, it is wise to tune the number file descriptor's on your operating system. HTTP connections are nothing more than TCP sockets on the operating system. All modern operating systems treat sockets as a specialized form of file access and use data structures called file descriptors to track open sockets and files for an operating system process. To control resource usage for processes on the machine, the operating system restricts the number of open file descriptors per process. You should be aware that all TCP connections that have been gracefully closed by an application will go into what is known as the TIME_WAIT state before being discarded by the operating system.
On most unix systems you can use netstat -a | grep TIME_WAIT | wc -l to detemine the number of socket in time_wait state. You have to check with your system adminstrator how to tune the tcp_time_wait_interval. On solaris you can use: /usr/sbin/ndd -set /dev/tcp tcp_time_wait_interval 60000

Debug BAPI Values

Being a newbie to Abap ,i am looking, howto debug BAPI input values-variables? Values(values of BAPI Import parameters ) are being passes to BAPI from Mobile app.
How/where can we check the values being passed to BAPI in R3 i.e the values with which the BAPI is being executed ?
Following the post Debugging , i understood a break point might help to debug the values, but i am confused at which line of code ?

Before starting the mobile app, you set external break-point for that particular bapi and run the app..
Set the external point at the line where you are passing the input to mbo. (import parameter of the BAPI).
Under Source code, you will find the details. e.g. for the given screenshot i have 2 inputs (at line # 23, 24) so i can set the external break-point at 23.
You can check this thread How to debug RFC function module in ECC 6.0

"New" error during ApplyLogOnInfo(...): Invalid parameter value: exceeds...

Invalid parameter value: exceeds the Min or Max or conflicts with existing value or edit mask
error during ApplyLogOnInfo() to the tables contained within a report. Now, this is a "new" error because this was not being thrown when the application was compiled for .Net 1.1 using the Crystal Reports v9.1.5000.0 components. When the application was migrated to .Net 2.0, and set to reference the the 10.2.3600 set of managed components, this started appearing.
Also, this will only occur on certain .rpt files that are loaded, and can be thrown when also executing the VerifyDatabase() method. By certain .rpt files, I mean those that have been opened and saved with Crystal Reports 2008 (warning message when saving indicated that the report will not be able to be opened in Crystal Reports versions earilier the 9.0; should I not assume this is correct?).
' Load a report that had been created in v10, but opened and saved in v12
Dim sFileName As String = "C:\test\CR2008Report1.rpt"
crReportDocument.Load(sFileName, OpenReportMethod.OpenReportByDefault)

Right, I am aware of the IDE plugin functionality (BTW, I'm going to guess no, but is the functionality present in the "Express" editions?). When a viewer application is created in VS, you can convert/open it in #d and have all of the designer props/pages available. When manually adding the viewer in a new #d project, you can add it, but it doesn't show up visually in the forms designer window (boggle).

I will investigate this probably tomorrow...

Yes, there are parameters embedded (?) in the .rpt. There are no parameters added at runtime; only the parameter values are set at runtime.

The important parameters controlling behaviour of the Proxy Plugin

The 7.0 Proxy Plugin has various crucial parameter controlling its operation. These are n:
#1. poll-timeout parameter that determines how long it waits for a reply before
considering a request as having failed.
The poll-timeout can be increased by adding the poll-timeout parameter to the end of
the Service entry within the obj.conf file. For example:
Service type="magnus-internal/passthrough" fn="service-passthrough"
servers="http://sunflash.red.iplanet.com" poll-timeout="600000"
Default timeout is 5 minutes, or 300000 milliseconds
Maximum timeout is 6 hours, or 21600000 milliseconds
Minimum timeout is 1 second, or 1000 milliseconds
#2. connect-timeout parameter that determines how long to wait for a connection
Minimum = 10 ms
Maximum = 75 seconds (75 * 1000)
Default = 5 seconds (5 * 1000)
#3. connect-interval parameter that determines Interval between connect() calls
Minimum = 10 ms
Maximum = 30 seconds (30 * 1000)
Default = 500 ms
AND
#4. keep-alive-timeout parameter that determines Maximum time to let connections idle
Minimum = 0
Maximum = 6 hours (6 * 60 * 60 * 1000)
Default = 30 seconds (30 * 1000)

But given that the prolem at hand is Boolean, why not make a simple straightforward approach:
!((a & b) | (a & c) | (a & d) | (b & c) | (b & d) | (c & d)), which leads to
!((a & (b | c | d)) | (b & (c | d)) | (c & d)) or
boolean xor(final boolean a, final boolean b, final boolean c, final boolean d) {

}I consider this an acceptable solution, too.
EDIT:
No, not anymore! It may look nice and all, but is not quite XOR... so I apologize for being careless and not double-checking what I wrote (my "xor" returns true even if all arguments are false) -- sorry!
This should (hopefully) be correct:

Aarrgh, but it's still horribly wrong! Made the same mistake twice, now I'll take some time to really think before totally embarrassing myself today...

Iplanet proxy plugin issue; simple but iam confused; Please Help !!

Hi All,
Iam using Iplanet proxy plug-in with BEA weblogic6.1. In simple terms. the iplanet webserver proxies any dynamic requests to the application tier(wls6.1)
And we have configured the proxy plug-in to show the debugging information on to __WebLogicBridgeConfig page.
Now, could somebody explain more about the "requests:" and "successful requests:" that is been shown on the iplanet proxy plugin's __WebLogicBridgeConfig ???
I mean i understand that "requests:" are the Total # of request that proxy plugin received. And "successful requests:" are the # of requests that went pass through to the wls server. But what happen to the requests which are UN successful requests .....i have seen the fugures like this:
"requests:2000" "successful requests:1900"
then what happened to these 2000-1900=100 requests.....why is there difference and why does this happen???
how can calculate these UNsuccessful requests in my iplanet proxy logs ???
please advise. I would really really appreciate your help on this.
-san

In more simple terms and to eloborate more on what iam asking, how can an HTTP request become unsuccessful ?
Again, more specifically, is __WebLogicBridgeConfig shows information of unsuccessful for the application tier OR any unsuccessful requests for the web tier ?

Need Help: Dynamically displaying parameter values for a procedure.

Problem Statement: Generic Code should display the parameter values dynamically by taking "package name" and "procedure name" as inputs and the values needs to be obtained from the parameters of the wrapper procedure.
Example:
a) Let us assume that there is an application package called customer.
create or replace package spec customer
as
begin
TYPE cust_in_rec_type IS RECORD
cust_id NUMBER,
,cust_name VARCHAR2(25) );
TYPE cust_role_rec_type IS RECORD
(cust_id NUMBER,
role_type VARCHAR2(20)
TYPE role_tbl_type IS TABLE OF cust_role_rec_type INDEX BY BINARY_INTEGER;
Procedure create_customer
p_code in varchar2
,p_cust_rec cust_in_rec_type
,p_cust_roles role_tbl_type
end;
b) Let us assume that we need to test the create customer procedure in the package.For that various test cases needs to be executed.
c) We have created a testing package as mentioned below.
create or replace package body customer_test
as
begin
-- signature of this wrapper is exactly same as create_customer procedure.
procedure create_customer_wrapper
p_code in varchar2
,p_cust_rec customer.cust_in_rec_type
,p_cust_roles customer.role_tbl_type
as
begin
//<<<<<---Need to display parameter values dynamically for each test case-->>>>>
Since the signature of this wrapper procedure is similar to actual app procedure, we can get all the parameter definition for this procedure using ALL_ARGUMENTS table as mentioned below.
//<<
select * from ALL_ARGUMENTS where package_name = CUSTOMER' and object_name = 'CREATE_CUSTOMER'
but the problem is there are other procedures exists inside customer package like update_customer, add_address so need to have generalized code that is independent of each procedure inside the package.
Is there any way to achieve this.
Any help is appreciated.
// >>>>
create_customer
p_code => p_code
,p_cust_rec => p_cust_rec
,p_cust_roles => p_cust_roles
end;
procedure testcase1
as
l_cust_rec customer.cust_in_rec_type ;
l_cust_roles customer.role_tbl_type;
begin
l_cust_rec.cust_id := 1;
l_cust_rec.cust_name := 'ABC';
l_cust_roles(1).cust_id := 1;
l_cust_roles(1).role_type := 'Role1';
create_customer_wrapper
p_code => 'code1'
,p_cust_rec => l_cust_rec
,p_cust_roles => l_cust_role
end;
procedure testcase2
as
l_cust_rec customer.cust_in_rec_type ;
l_cust_roles customer.role_tbl_type;
begin
l_cust_rec.cust_id := 2;
l_cust_rec.cust_name := 'DEF';
l_cust_roles(1).cust_id := 2;
l_cust_roles(1).role_type := 'Role2';
create_customer_wrapper
p_code => 'code2'
,p_cust_rec => l_cust_rec
,p_cust_roles => l_cust_role
end;
end;

Not possible to dynamically in a procedure, deal with the parameter values passed by a caller. There is no struct or interface that a procedure can use to ask the run-time to give it the value of the 1st or 2nd or n parameter.
There could perhaps be some undocumented/unsupported method - as debugging code (<i>DBMS_DEBUG</i>) is able to dynamically reference a variable (see Get_Value() function). But debugging requires a primary session (the debug session) and the target session (session being debugged).
So easy answer is no - the complex answer is.. well, complex as the basic functionality for this do exists in Oracle in its DBMS_DEBUG feature, but only from a special debug session.
The easiest way would be to generate the wrapper itself, dynamically. This allows your to generate code that displays the parameter values and add whatever other code needed into the wrapper. The following example demonstrates the basics of this approach:

SQL> create or replace procedure FooProc( d date, n number, s varchar2 ) is
