How to avoid multiple DataConnections with LCD ES2

Hi, we are just starting using the data connections to connect via a database with LiveCycle Designer. It seems we are missing something important regarding to manipulation of data from the PDF.
At first we have tried to apply a INSERT command to our first table and be able to browse through the items in the database. We are able to browse through the database only before we have inserted something.
If we insert an item and then try to browse through the database with (Next, Previous, Last or First) it will crash and have an error of the following :
(Next, Previous, Last or First) failed. Multiple-step operation generated errors. check each status value [ID:@11]
So then we have decided to create a second data connection which would have each of the column in the database except for the ID which appears to make everything crash.
E.G.: Table_1
DataConnection1 --> ID, Field1, Field2, Field3, Field4 SELECT Command connection
DataConnection2 --> Field1, Field2, Field3, Field4 INSERT Command connection
Seems like we can't have a SELECT and INSERT in the same DataConnection because with those 2 different connections it works fine....
Then we are trying to show multiple data's in a table which is linked with the ID of the Selected ID in DataConnection1.. To show the data is all fine using a 3rd connection for that Table_2, then we are making sure a blank row is always there at the end of the table to be able to add this new entry to the database with a Add button to INSERT into the Table_2... Unfortunately we do not have a 2nd connection to that table because we cannot link those fields with the database for the purpose of a multiple entry view.
We have tried to make a 2nd connection for the purpose of the INSERT but it doesnt work at all.
We are basing ourselves on the sample provided by Stefan Cameron in his blog http://forms.stefcameron.com/2006/12/18/databases-inserting-updating-and-deleting-records/
I am wondering if we are using the right functionalities and if it is the simplest way to work with databases...
If anyone can help, it would be greatly appreciated!!
Thanks in advance!

Don't forget to activate the RESOURCE_LIMIT parameter, which default is FALSE :
alter system set RESOURCE_LIMIT = true;
Laurent, I had a similar problem some time ago : I didn't want to avoid multiple access, but only control who was doing what. That's because moving from Client/Server to Web the TERMINAL column in V$SESSION becomes useless.
I tried your solution, but I had to give up with it, because in my Forms9i application some forms call Reports, which generate a new session.
I decided to use DBMS_APPLICATION_INFO, and this is satisfactory for my requirements, but I'm interested to discover other solutions.
P.S. with my solution I'm able to limit accesses, because in the CLIENT_INFO string I put, among other things, the
application user, so I can control if an user is already connected. The problem is that existing applications have to be modified .....:-(

How to avoid multiple copies of data in page refresh

If you are talking about a page with an insert query, ignore the fact that it's a page refresh. It's just another way that someone can insert duplicate records. I like to handle this in my insert query.
insert into thetable
(f1, f2, etc)
select distinct
value1, value2, etc
from some_small_table
where you don't already have that record

How to move multiple clips with transitions?

Im still transitioning from FCP7 to FCP 10.1.2 and can't believe I have missed the lesson that explains how to move multiple clips with transitions.
Up till now I have tried several work arounds including deleting all the transitions then using the (P) Position tool to move the clips from the primary track to some track above it then re adding all the transitions. This is a function I do on a daily basis. Am I missing something? Please help!
Thank you

With some further investigation, the transitions have nothing to do with my problem. In my case there was a tiny “Black gap slug” within the group that was preventing me from being able set it on top of another group of clips or gap someplace. But even with the gap removed… I can move the clips on top of another group but the transitions stay behind on the primary (Magnetic)
In the screen shot you can see what happens when I move a group out of the primary (magnetic) timeline onto a gap. All the transitions get left behind.
Ive notices that Cutting and pasting will only paste the sequence some other place on the primary (magnetic) timeline for me.
An example of why I would want to put a cropped/ resized group on top of another group is to do picture in picture effects or if I wanted to create a background behind a set of adjusted clips.

How to avoid multiple listing for same artist?

How to avoid multiple listing for same artist?

Sounds like there might be blanks in the artist name.
For instance "Lou Reed" and "Lou Reed_" will not match.
(Pretend the underscore _ is a blank).
Select all the Lou Reed songs, Get Info, and type "Lou Reed" in the artist field. That should fix it.

How to avoid multiple password prompt for intarnet portal

we have developed a intranet portal in Share Point 2013 with multiple site collection. when accessing through IE, Chrome, we can do settings to avoid multiple password prompt by adding the domain name of site in Trusted sites. How we can achieve the same in Safari while accessing through MAC or IPAD

first time when you call the BSP application from the browser (or by double clicking the BSP_APPLICATION link from SAP GUI) you need to pass user credentials. For further windows this will not be required as browser will remember your info.
if you need to <b>somehow</b> avoid this then the only option is to hard code the user id and password in the service in transaction SICF or by passing the same via URL.
Another option is that if you port this application in a SAP portal environment, SSO can be used .
Hope this helps.

How to handle multiple clients with DatagramSocket

I am trying to handle multiple clients with 1 datagramSocket bind to one port (basically I have only one port to use, and I can not use TCP or any other ports). At the server side I have two threads one for receiving packets and buffering them, another for processing the packets in the buffer and sending replies.
I can have multiple clients sending datagramPackets to me and I will have to process the packets and send them to DIFFERENT clients. Ex. Client 1 sends datagramPacket to Server which sends the processed packet to Client 2. Also Client 2 sends a datagramPacket to Server which again processes the packet and sends it to Client1. May have Client 3 and 4 doing the same thing at the same time... and so on...
My root class is creating the datagramSocket(somePort) and two threads (receiver and sender). How can I use the socket that I created in these two threads??
I have done the following and I am getting "java.net.bindexception". When I am sending stuff from Client1 to Client2 everything is fine but when I start sending something from Client2 to Client 1, I get the bindexception... Client 1 is using port 3000, Client 2 is using port 4000.
I really don't have a lot of experience in socket programming so I am not sure if there is a much simpler way to do this. I appreciate all the tips and help that I can get...
Thanks...

      static void processDataMsg()
         DatagramPacket op;
         InetAddress DA = null;
         int DP = 0;
         byte [] outPacket = null;
         // POP FROM RECEIVE BUFFER
         // SOME PROCESSING HERE
         // Set Destination Address (DA)
         // Set Destination Port (DP)
         // DA and DP are the forwarding IP and Port addresses
         // not the addresses original packet was sent from.
         try
          op = new DatagramPacket (outPacket, outPacket.length,DA, DP);
          udpSocket.send(op);
         catch (IOException e)
          e.printStackTrace();
}Also for development and testing purposes, I am running the two clients and the server on the same machine (windows xp-32b) so all of the Destination IP Addresses are 127.0.0.1. and as I said Ports that I am using are 2000, 3000, 4000 (Server, Client1, Client2).

Hmm I have minimized the code and it seems to be working now.
I think I have an error in the header portion of the data I am sending, where I am storing the source IP/Port and destination IP/Port. I think the server in the middle is messing these values up while sending them to the destination Client. Because the destination client actually receives the stuff and sends the reply back to the server, but the reply packet's headers has 0/0 as the dest IP / Port...
Server is giving me java.net.BindException: Cannot assign requested address error when it tries to forward the reply it received from the client2 as the address it is trying to send is 0!
I guess it doesnt just give this error when you try to open two sockets to the same port...
Paul, Thanks for the direction on how to proceed... took me a while get the minimized code but at least figured out the problem. Well still have to make sure that is THE problem though :)
As far as the statics goes how can I change those to non static ones? Where do I make an instance of the top level class that creates the threads? and how do I pass the DatagramSocket to the threads/ if I dont need to pass how do I call or use the datagramSocket I created in the top level class? I mean do I still kinda have it like a global variable on the top?? A very simple example would be much appreciated...
I think these might be really basic questions but I am having a rough time with the hierarchy in java...

How to avoid multiple call to function:

In our datawarehouse we have a huge receipt row table where all metrics ar stored in the local currency. On top over that we have views which calculate metrics to the desired currency.
So basically all views looks like this
select geo_region,
product_group,
customer_group,
metric1 * (select get_exchange_rate(currency_id) from dual) metric1,
metric1 * (select get_exchange_rate(currency_id) from dual) metric2,
metric1 * (select get_exchange_rate(currency_id) from dual) metricx,
group by..
As we have about 20 metrics we notices that the function is called 20 times per row.
Is there really anyway to avoid that? Shouldn't it be it's just the exact same call with the same in-parameters over and over again.
We've tried with local sys_context and the performance is better but the call to the context is still performed 20 times. Any Ideas?

Can you avoid multiple function calls? Maybe, if as in your example all the function calls values are computing the same result. If they operate on different columns then you'll have to perform the function call anyway.
Either way you should be able to eliminate the (near as I can tell) pointless subquery from dual
You might be able to avoid the repeated function calls if the values are always the same. If every computation you could save the function call (and subquery!) by doing it once and then using assignments after the initial query using variables after the initial query, perhaps using NULL in the query as placeholders to select into a record - something like
select inital_region,
         product_group,
         customer_group,
         metric1 * exchange_rate(currency_id) metric1,
         null metric2,
v_metric2 := metric1;

How to schedule multiple reports with different local to change static field language ?

Hi all,
we have requirement that we will place multiple schedule request on same server ,This schedule request will be different local setting with parameter value like: en-GB,en-US,Chinese...etc .We used translation Manager for this and it takes this parameter and change report language for static fields.
problem is that ,on server it is not working properly,we tested for one report .if we pass prompt value to change local setting in report the we need to log off and login again in CMC to reflect new local or on BI Launchpad we need to refresh page then it shows new language.
How we can do this with multiple scheduled report which will have different local value like en-GB,en-US,Chinese,German....?These schedule request are getting placed in server by one user .
Please help us with sample code.
Thanks
Madan

Hi,
The only approach I can think of is to create a template report which uses variables
For each column you would need to variable
v_columnAName and v_columnAValue
v_columnAName would have a if statement in it
=if([client]="clientA" or [client]="clientC";NameOf([firstName]);if([client]="clientB";NameOf([SSN]);NameOf([lastName]));
v_columnA would have a if statement in it
=if([client]="clientA" or [client]="clientC";[firstName];if([client]="clientB";[SSN],[lastName]));
This would only work when you had a small set of clients.
This might be more managable if it was done in the universe

How to avoid multiple votings?

Hello All. How can I avoid, that there are multiple votings from one person?

I think there is no option to avoid multiple votings. Adobe has not implemented this funktion.
Formstack is as alternative to Formcentral. The Fieldoption there is called - Unique.
Unique allows you to restrict submissions of the same value in this field. For example, you can allow only one submission for a particular email address or physical address.
That is the option i was looking too.
Formcentral is useless for me in this way.
