Is it possible to use dependent parameters in discoverer

Dear All,
Is it possible to use dependent parameters in discoverer... Like in RDF's(concurrent program)
Reddy.

Hi Hussain,
I think In Discoverer 4i there is no optional parameters Option.I wrote in condition(Desktop addition) like Org = :Org_param or org = DECODE(:"Org Parameter 1",'All',Org) .
At the time of running work book I am passing 'All' in parameter it's taking all orgs and giving org's data.
But in application i am not able give 'All' in parameters.
how to do optional parameters in 4i.
In 10G Optional parametes are there.
Regards,
Reddy

USE OF PARAMETERS IN DISCOVERER

Hi, from El Salvador my question is? in a query that have parameters, when customize the parameters, how can put TO_DATE(SYSDATE)-1 in default value ?

Hi,
You cannot more a worksheet, only a workbook. To move a workbook between instances you have to either use Discoverer Desktop and save the workbook to the desktop, or you can use the Discoverer Admin 4i command line and export the workbook to a .eex file then import the workbook into the new instance.

Dependent Parameters in Discoverer Desktop

Hi All,
I am using discoverer 10g. i dont know how to filter the second parameter based on the first parameter selection in the Discoverer Desktop.

Hi,
It only exists in the Plus.
There are some differences between the plus and desktop for ex sub queries that can be done in desktop and not plus.
Any way if you'll create it in plus you will be able to use it in desktop but you cannot create it using the desktop edition.

How to use event parameters?

Hi
I've made simple eem applet for shutdown the port which trigered storm control event.
It is look like that:
event manager applet shut-storm
event storm-control
action 1.0 cli local python bootflash:shut-storm.py
and the script is
from cisco import CLI
from cisco import cli
import sys
import datetime
import time
import re
whitelist = [
"Ethernet1/1",
"Ethernet1/2"]
shlog = CLI('sh logg last 100 | i ETHPORT-5-STORM_CONTROL_ABOVE_THRESHOLD | last 3',False).get_output()
pat = re.compile(r'(\d{4} \w{3} \d{2} \d\d:\d\d:\d\d) \S+ \%ETHPORT-5-STORM_CONTROL_ABOVE_THRESHOLD: Traffic in port (Eth\S+|[Pp]o\S+)')
now = datetime.datetime.now()
delta = datetime.timedelta(seconds=180)
for l in shlog:
mobj = pat.match(l)
if mobj:
    port       = mobj.group(2)
    logTimeStr = mobj.group(1)
    logTimeObj = time.strptime(logTimeStr, "%Y %b %d %H:%M:%S")
    logTime    = datetime.datetime(*logTimeObj[:6])
    if now-logTime < delta:
      if port not in whitelist:
        cli("conf t")
        cli("interface %s" % port)
        cli("shutdown")
But the python script is a bit complecs because it shoud find triggered interfece in log.
Is it possible to use event parameters? And how?
I know that they are:
sw1# sh event manager history events det
Event ID Time of Event        Event Type                   Slot       Policies
32       09/30/2013 15:40:51 storm_control                active(1) shut-storm
    interface = "Ethernet1/16", cause = "storm-control"

Thank you Joseph.
It works.
Now the applet looks like:
event manager applet shut-storm2
event storm-control
action 1.0 cli local python bootflash:shut-storm2.py $interface
And the script:
from cisco import cli
from syslog import syslog
import sys
whitelist = [
"Ethernet1/1",
"Ethernet1/2"]
port = sys.argv[1]
if port not in whitelist:
cli("conf t")
cli("interface %s" % port)
cli("shutdown")
syslog(2, "Interface %s was shutdown due to storm conditions" % port)

Is it possible to use a case statement when joining different tables based on input parameters?

Hi,
I have a scenario where my stored procedure takes 5 parameters and the users can pass NULL or some value to these parameters and based on the parameters, I need to pull data from various tables.
Is it possible to use a case statement in the join, similar the one in the below example. I'm getting error when I use the below type of statement.
select a.*
from a
case
when parameter1=1 then
inner join a on a.id = b.id
when parameter1=2 then
inner join a on a.id = c.id
end;
Please let me know, if this type of statement works, and if it works will it create any performance issues?. If the above doesn't work, could you please give me some alternate solutions?
Thanks.

Here's a technique for joining A to B or C depending on the input parameters. In theory, you are joining to both tables but the execution plan includes filters to skip whichever join is not appropriate. The drawback is that you have to do outer joins, not inner ones.
CREATE TABLE A AS SELECT LEVEL ak FROM dual CONNECT BY LEVEL <= 100;
CREATE TABLE b AS SELECT ak, bk
FROM A, (SELECT LEVEL bk FROM dual CONNECT BY LEVEL <= 10);
CREATE TABLE c(ak, ck) AS SELECT ak, bk*10 FROM b;
variable p1 NUMBER;
variable p2 NUMBER;
exec :p1 := 1;
exec :p2 := 20;
SELECT /*+ gather_plan_statistics */ A.ak, nvl(b.bk, c.ck) otherk FROM A
LEFT JOIN b ON A.ak = b.ak AND :p1 IS NOT NULL AND b.bk = :p1
LEFT JOIN c ON A.ak = c.ak AND :p1 is null and :p2 IS NOT NULL and c.ck = :p2
WHERE A.ak <= 9;
SELECT * FROM TABLE(dbms_xplan.display_cursor(NULL,NULL,'IOSTATS LAST'));

LEFT JOIN b ON A.ak = b.ak AND :p1 IS NOT NULL AND b.bk = :p1

SELECT * FROM TABLE(dbms_xplan.display_cursor(NULL,NULL,'IOSTATS LAST'));
Now table B is not accessed.

Possible to use parameters in MDX Studio?

Is it possible to use parameters in MDX Studio? I've tried using SSRS2008 for query design but...
SSRS2008 query designer complains that parameters do not exist when they quite obviously do ( in the report)
LaCie drives. Failing when you need them most."La" meaning "Terrible", "Cie" meaning "customer service"

You can declare parameters in XMLA format after the MDX query - see examples in this post:

Possibility to transfer additional parameters in outbound XML message

Hi,
is there any possibility to transfer additional parameters in outbound XML message using (BADI: BBP_SAPXML1_OUT_BADI).
Additional parameters are,
1. Communication Method for the Business Partner
2. R/3 Vendor # & logical system for Business Partner
3. Relationship between Business Partner Number and R/3 Vendor Number is BP GUID.
How can we extended the structure in the BADI.
Please give me qucik response.
Thanks & Regards.
Surya

Look for structure which the interface parameters are referring, there you should see some dummy structures referring to INCL_EEW* for e.g. in PO header INCL_EEW_PD_HEADER_SSF_PO. Add additional fields and pass the data accordingly.

[CS3 JS SDK] Possible to Use HTTP URLs for Links?

I am attempting to use JavaScript to implement a connector from CS3 (InDesign/InCopy in my case) to our content management system. Our CMS provides an HTTP-based API. By using the HttpConnection object (from the Bridge code, see posts on "httpwebaccess library") I can access our repository using HTTP URLs and, for example, get an InDesign document or INX file (and the UI support in CS3 scripting makes it possible for me to build all the UI components I need without having to write a true plugin).
However, what I *can't* seem to do is create Link objects that use a URL, rather than a File, to access resources.
My goal is to be able to store in our repository InDesign documents that use URLs to other resources in the repository for links (e.g., to graphics and InCopy articles).
However, as far as I can tell from the scripting documentation and my own experiments, the URL property on Link is read-only in JavaScript (even though the scripting API HTML indicates it's a read/write property) and Link instances can only be constructed using File objects.
My question: have I missed some trick in the scripting API (or elsewhere) that would allow me to create links that use URLs instead of files (and having done so would InDesign resolve those URLs?)? Our repository does support WebDAV, so that might be an option, but it would depend on mounting WebDAV services in consistent places on client machines, which is dicey at best, given the weak nature of the WebDAV clients on both Windows and OS X).
Or are my only options to either copy linked resources to the client's local file system (or a shared network drive) or implement a plugin that implements my desired behavior for links?
And if the answer is a plugin, will that even work?
This is in the context of CS3. Has the Link mechanism changed at all in CS4 such that I could do what I want in CS4 where I cannot in CS3?
Thanks,
Eliot

Hi,
It is not possible to use HTTP URLS in CS3. You will have to create a plug-in to use Custom Data Links.
I think it is possible to use HTTP URLs in CS4 as per the User Guide.

Is it possible to use BAPI-ALE to send an idoc using the message control?

Hi Guys
Is it possible to use BAPi-ALE to send an IDOC using a message control?
I have configured the system to send an IDOC when a outbound delivery is saved in the system.
I have done the following.
1). I am using the std BAPI-ALE interface provided by the object type LIKP.
2). I am using the method SAVEREPLICA for which an interface already exists in BDBG transaction.
3). I hace created a distribution model in BD64 and added the BAPI - LIKP and SAVEREPLICA
4). Created a partner profile ( using the generate partner profile option in the BD64 transaction )
QUESTION:
1). How do i associate the custom OUTPUT type created for Delivery ?
2). I tried to associate the custom output type in the Partner profile definition under the message control tab but i am not sure which Process code to be used? Since the partner profile was generated automatically from BD64 it has an entry for SHP_OBDLV_SAVE_REPLICA as a message type in the outbound parameters. and i am unable to find a process code for this Message type in WE41. So what process code should i use in the Message control tab against the custom output type?
3). Do i need to leave the message control tab empty without making any entry? If yes then how would the system come to know that it needs to trigger this partner profile when the custom output type is proposed by the system?
will award points for useful answers

Is it possible to use a Linksys By Cisco Wireless-G Internet Home Monitoring Camera with Labview

I was wondering if it is possible to use a 'Linksys By Cisco Wireless-G Internet Home Monitoring Camera' with Labview
http://www.dabs.com/productview.aspx?Quicklinx=53PX&SearchType=1&SearchTerms=network+cameras&PageMod...
I wan't to be able to get the raw data from the camera and analyse it.
Message Edited by Jam.hall on 03-25-2009 09:03 AM
Solved!
Go to Solution.

Hi Jam.Hall
I am somewhat hesitant to say you will be able to use this camera with LabVIEW. It all depends on what functionality you are wanting to utilise on the camera, and how much video you want to analyze.
- If you want to use the wireless functionality, I am concered that the on board web server will compress and embed the video stream. I do not beleive this is something we can access in LabVIEW.
- If you wish to use the ethernet connection, if it is Gigabit Ethernet, then you should be able to use our IMAQ for GigE driver to bring in the feed, but looking at the specs for the camera, I'm not sure that this is an option.
- My other suggestion might be to utilise the record video stream function that the camera has. Depending on the format of the video file, you may be able to read in the recorded file and analyse it in LabVIEW.
If you could explain the purpose of your application, and what you would like to achieve with the system, there may be more suitable products that you can use.
Kind regards,

Is it possible to use a camera phone as your webcam?

I have a Nokia N73 camera phone is it possible to set it up to use it as my camera for iChat?

My reply would be .....
It will depend on the type of Output the camera has.
It may just be possible to use the iChatUSBCam Utility http://www.ecamm.com/mac/ichatusbcam/ which does have a trial period.
As the camera is unlikely to have Mac Drivers it is less likely.
Although iChat may see it as being Self contained like a Camcorder and the format will be the key if the input is over USB.

Using named parameters with an sql UPDATE statement

I am trying to write a simple? application on my Windows 7 PC using HTML, Javascript and Sqlite. I have created a database with a 3 row table and pre-populated it with data. I have written an HTML data entry form for modifying the data and am able to open the database and populate the form. I am having trouble with my UPDATE function. The current version of the function will saves the entry in the last row of the HTML table into the first two rows of the Sqlite data table -- but I'm so worn out on this that I can't tell if it is accidental or the clue I need to fix it.
This is the full contents of the function . . .
     updateData = new air.SQLStatement();
     updateData.sqlConnection = conn;
     updateData.text = "UPDATE tablename SET Gsts = "Gsts, Gwid = :Gwid, GTitle = :GTitle WHERE GId = ":GId;
          var x = document.getElementsById("formname");
          for (var i = 1, row, row = x.rows[i]; i++) {
               updateData.parameters[":GId"] = 1;
               for (var j = 0, col; col=row.cells[j]; j++) {
                    switch(j) {
                         case 0: updateData.parameters[":GTitle"] = col.firstChild.value; break;
                         case 1: updateData.parameters[":Gsts"] = col.firstChild.value; break;
                         case 2: updateData.parameters[":Gwid"] = col.firstChild.value; break;
Note: When I inspect the contents of the col.firstChild.value cases, they show the proper data as entered in the form -- it just isn't being updated into the proper rows of the Sqlite table.
Am I using the named parameters correctly? I couldn't find much information on the proper use of parameters in an UPDATE statement.

Thank you for the notes. Yes, the misplaced quotes were typos. I'm handtyping a truncated version of the function so I don't put too much info in the post. And yes, i = 1 'cuz the first rows of the table are titles. So the current frustration is that I seem to be assigning all the right data to the right parameters but nothing is saving to the database.
I declare updateData as a variable at the top of the script file
Then I start a function for updating the data which establishes the sql connection as shown above.
The correctly typed.text statement is:
        updateData.text = "UPDATE tablename SET Gsts=:Gsts, Gwid=:Gwid, GTitle=:GTitle WHERE GId=:GId";
(The data I'm saving is entered in text boxes inside table cells.) And the current version of the loop is:
        myTable = document.getElementById("GaugeSts");
        myRows= myTable.rows;
          for(i=1, i<myRows.length, i++) {
               updateData.parameters[":GId"]=i;
               for(j=0; j<myRows(i).cells.length, j++) {
                    switch(y) {
                         case 0: updateData.parameters[":GTitle"]=myrows[i].cells[y].firstChild.value; break;
                         case 1: updateData.parameters[":Gsts"]=myrows[i].cells[y].firstChild.value; break;
                         case 2: updateData.parameters[":Gwid"]=myrows[i].cells[y].firstChild.value; break;
                         updateData.execute;
The whole thing runs without error and when I include the statements to check what's in myrows[i].cells[y].firstChild.value, I'm seeing that the correct data is being picked up for assignment to the parameters and the update. I haven't been able to double check that the contents of the parameters are actually taking the data 'cuz I don't know how to extract the data from the parameters. ( The only reference I've found so far has said that it is not possible. I'm still researching that one.) I've also tried moving the position of the updateData execution statement to several different locations in the loop andstill nothing updates.
I am using a combination of air.Introspector.Console.log to check the results of code and I'm using Firefox's SQlite manager to handle the database. The database is currently sitting on the Desktop to facilitate testing and I have successfully updated/changed data in this table through the SQLite Manager so I don't think I'm having permission errors and, see below, I have another function successfully saving data to another table.
I currently have another function that uses ? for the parametersin the .text of a INSERT/REPLACE statement and that one works fine. But, only one line of data is being saved so there is no loop involved. I tried changing the UPDATE statement in this function to the INSERT/REPLACE just to make something save back to the database but I can't make that one work either.I've a (And, I've tried so many things now, I don't even remember what actually saved something --albeit incorrectly --to the database in one of my previous iterations with the for loops.)
I'm currently poring through Sqlite and Javascript tomes to see if I can find what's missing but if anything else jumps out at you with the corrected code, I'd appreciate some ideas.

Using Custom Parameters

Hi, I have been asked to ensure that the isolation level is set to read uncommitted when a business objects query is executing. I have had a read around the forums and it appears that this should be possible by using the custom parameters in the universe but I have'nt been able to get it to work. Using XIR2, I have a universe set up pointing at AdventureWorks on SQL Server 2005 and the report is based on this. The parameter I have set is called ConnectINIT and I have given it the value of "SET TRANSACTION ISOLATION LEVEL READ UNCOMMITTED". In order to test the results I have created an object ('Isolation Level') that contains the select statement
(select transaction_isolation_level from sys.dm_exec_requests where command = 'SELECT')
so in my report I am expecting to see this object return 0 for all rows if the isolation level is 'Read Uncommitted'. However it is returning 2. The sql generated by Business Objects is:
SELECT
HumanResources.Employee.Title,
Person.Contact.FirstName,
Person.Contact.LastName,
Person.Address.AddressLine1,
Person.Address.AddressLine2,
Person.Address.City,
Person.Address.PostalCode,
Person.Contact.Phone,
Person.Contact.EmailAddress,
(select transaction_isolation_level from sys.dm_exec_requests where command = 'SELECT')
FROM
HumanResources.Employee,
Person.Contact,
Person.Address,
HumanResources.EmployeeAddress
WHERE
( HumanResources.Employee.EmployeeID=HumanResources.EmployeeAddress.EmployeeID )
AND ( HumanResources.Employee.ContactID=Person.Contact.ContactID )
AND ( HumanResources.EmployeeAddress.AddressID=Person.Address.AddressID )
Can someone tell me if this is a valid test, and offer some advice on what I am doing wrong?
Thanks,
Colin

my understanding was that these parameters only worked with Oracle not with SQLServer. I am open to correction.

Is it possible to use page-scope beans in value expression ?

Is it possible to use page-scope beans in value expressions ?
For example,
<c:forEach items="${DataScreens.records}" var="record" status="status">
<tr>
<td><h:command_link action="#{DataScreen.editRecord}">
                <h:output_text value="#{DataScreen.modifyLabel}" />
               
               <f:parameter name="id" value="#{status.count}" />
          </h:command>
</td>
<td>...</td>
<td>...</td>
</tr>
</c:forEach>In my case, I want to use JSTL instead of <h:dataTable>, because of some special
requirements in this screen. Can someone please provide me with a workaround ?
I get the following error on execution..

Hello Ajay,
I cant really understand how a particular style can be applied to only an individual column.In the simplest case the attribut 'columnClasses' of data_table contains
the same number of style classes as you have columns in your table. These
classes are then applied one to one to the columns.
If there are fewer classes than columns then you can think of the classes
beeing repeated until there is one class for each column. In the extreme
case of only one class this means that this class is applied to all columns.
The following example shows the simplest case of three columns
and three classes. Just remove one or two classes from the columnClasses
attribute to see the 'repeating' behavior.
