Forms client-side pl/sql procdures run in DB or Forms server?

Hi,
Does anyone know where Forms client-side pl/sql procdures and pll actually run?
We plan to convert forms application to web-based application. We want to take out and re-use only business logic in forms procdure/pll and still want to keep them in pl/sql language.
Our first option is to put the business logic as pl/sql stored procedures in DB server. But my clients worry about the DB server performance. My clients think that forms procedures run in forms server and moving them into DB server will result in additinal workload in DB server.
Every body says that the best place to execute pl/sql is
in the database. However if Forms client-side pl/sql procdures run in Forms server, is my client right?
If so, does anybody know how to make pl/sql procedure in a client-side PL/SQL package and call it from other language (Java or else)?
Hyunsu Kim

Forms PL/SQL will run in the Forms Server - if y want to share business logic accross multiple applications you could put it onto the database as you mention. You won't know if performace will be good or bad until you do some tests but its a pretty common scenario - and remember - what you MAY lose in terms of slower processing because of load, you will gain by eliminating network transfers between the Forms server and the database.

Which SQL Server Edition support how many sessions to the instance from SQL Management Studio on the client side

Hi,
I'm looking for some help on the below query to verify which version of sql server edition supports multiple or N number of sessions to the SQL server Instance using the SQL Server Management Studio tool from the client side.
SQL Standard Vs Enterprise.
your urgent help is much appreciated.

Hello,
See Maximum Capacity Specifications for SQL Server =>
User connections = 32,767; and this value is independent of use SQL Server Version, edition or the used tools, like SSMS in your question

Merging randomly-named XML data file on client-side with pdf designed in Livecycle 7.0 (and addition

Okay, as a heads up I work for a financial institution and we are converting our legacy "jetforms" to pdf format. I have in my staff for the project, 2 code developers and myself- a form designer. We have currently spent 2 months in trial and error attempting to resolve this problem, please let us know anything you can have. All client-side (internal) machines are running Windows XP and Adobe Reader 7.0.7
The software we use as a financial institution allows our users to export a customer's data file onto their machine which is then renamed to include the member's account number and first and last name for our staff to determine which data file they need more accurately. In legacy jetforms, we have developed a program that pushes the data from the customers file that they select, into the jetform that they want to open and the matching fields in the data file fill in the fields of the jetform. Clean and simple.
Now, i have hit nothing but frustration when attempting to perform the same process with pdfs using a form designed in livecycle designer 7. First, i see no obvious command for opening a pdf and importing a data file using a command line, like pdfmerge or something of the sort in which an xml data file can be specified and a pdf can be specified. I saw something like it using an fdf format and attempted to do this but apparently reader cannot import the data into the pdf that was designed adobe livecycle 7. All i have been seeing is database connections and using javascript inside the form to populate fields based on these database connections, etc. etc. or doing a manual file>import data>etc. which we don't want to have our staff do. We do not have reader extensions enabled, simply because i cannot get an adobe representative to call me and discuss pricing nor see any estimated pricing chart around. I don't know if reader extensions are necessary for this or not but i'm becoming very very frustrated with it.
We don't want a complex server-side data connection binding with dynamic input. No, we just want it where our developers can say "if this data file is selected, and this pdf form is selected run this command" which would be a simple pdfmerge type solution. Is this possible or do i need to stay with jetforms until our software the billion dollar financial institution uses does form building inside its own application? I don't want to fight about who is better, what version to use, etc. I just want the straight up honest truth. If you need to know the pricing that the reader extensions would have to go by, assume there will be 500 client computers that will need to use it.

From your post it sounds like you are Central Pro (a product for which I am by no means an expert), but you say you want to upgrade to a newer product from your "legacy" one. Is there a reason for this? Have your requirements change so that it no longer fits them? Central is still in the current Adobe roster and as far as I know there is no plans to get rid of it any time soon, so if it does everything you want I don't see why you would want to change.
There is no product in the LiveCycle suite that merges xml data into a form from the command line. LiveCycle (with the exception of Designer) is a suite of server products, so the closest you would come is LiveCycle Forms (merge the xml and create a fillable PDF) or LiveCycle Print (merge the xml and print the form).
Hope this helps somewhat.

Need to run one query to know total rows and size of table in MB , this i need to repeat for all tables which i got from input file.
finally write 'table name | total rows | size of table in MB' whole info in another CSV file at client side. this output CSV file name will contain timestamp.
Please guide me in detail how to read and write file avail at client side.

Password hashing on client side

Hi. I would like my users to have their passwords hashed in SHA1 at the client side when they login so that when the html form comes to the server, the password is hashed and in case if the form is being eavesdropped on , I do not need to worry about the passwords in plain since it's hashed.
I am not using SSL because there isn't much things to encrypt or hide secret other than just for the login passwords or users changing their user profile like updating their passwords. And SSL can add quite abit of cost to my client's web hosting budget.
So simply, is there anyway to hash passwords in client side using JSP before it is sent to the server ?

Not using jsp no, because JSP stands for Java SERVER Pages. Meaning that java/jsp only runs on the server.
You can do it in javascript client-side: http://www.movable-type.co.uk/scripts/sha1.html
But whats the point?
Now instead of sending what they user typed in, you send the hash of it.
If anyone is monitoring the line, they can just send the hash of it as well.
No protection is afforded you by doing this.
Hashing the password doesn't stop someone stealing it by tapping into the line.
What is DOES stop is somebody querying your database and saying "give me a list of username/passwords"

Client-side file I/O

hi,
we are trying to do client-side file I/O from PL/SQL. we have Oracle 8.1.7 here and looks like they have discontinued TEXT_IO after Ora-8. can someone give any ideas how we could write stuff in a file on the client-side in Oracle 8.1.7 ?
alternatively, how can i increase the display of DBMS_OUTPUT so i can print out a VARCHAR2(4000) variable.
thanks in advance,
Briti

TEXT_IO is a Forms built-in package, which is available to the client-side PL/SQL engine and accesses the client's filesystem.
UTL_FILE is a database package that is usuable from server-side code only, and accesses the server's filesystem.
I'm not quite sure what your problem is - could you elaborate?

How to call methos form server to client

Hello Friends
I m working in flex3.0 and i just want to know that how can i call a function from fms server to my AS3.0 (Client Side) code.
i tried the syntax client.call(methodname,null,null); but my flex code throw exception unable to call the method.
here can i use clientobject.call(methodname,null,null) and is there some special way to declare that method at client side.
can anyone put some demo code of both server side as well as client side so that i can undersatnd it properly.
Thanks and regards
Vineet osho

Hi,
You can try it the following way. On client side define the function on the netconnection object as
nc = new NetConnection();
nc.connect("rtmp://server-ip/app");
nc.client = new Object();
nc.client.someMethod = function(msg) {
//logic here
trace(msg);
On the server side you can use
clientObj.call("someMethod",null,"Hello");
I think this should get you some idea. However if you need more info or still run into issues please revert back,
Thanks,
Abhishek

ACE30 - PING to VIP and Client side SVI not working

Hi Guys,
Having setup the ACE30 based on the configuration guides, I've been able to get basic load balancing working, probes, stickness etc. However in testing connectivty, I've noticed that from the real server on the backend I cannot seem to PING:
1. The VIP for the web service that the server is a part of
2. The Client side SVI
I'd like this to work to ensure full connectivity.
I've applied ACLs to the Client side SVI (on the ACE) to allow this in both directions, and also removed any ACLs attached to the client side SVI on the MSFC where the subnet is actually homed. However I just cannot seem to PING the Client side SVI on the ACE, or the VIP. Trying to understand if this is normal behavior.
Have inserted my config below for completeness.

To ping your VIP of the webserver, you should apple the service-policy input command on VLAN 186 too. Currently the VIP only listens on VLAN 11. For the SVI i think that was forbidden by security reason, but i cant remember anymore. Maybe you just need to put the management policy on the interface VLAN 186. If it dont work, then my first guess was right

Popping up a dialog box on client side for authentication in a proxy server

hi all,
we have wriiten a code for proxy server.now we want to add the authentication code in the same which will authenticate client by popping up a dialog box on the client side.though no code runs on the client side.only the client has to open the browser and enter the credentials.
we dont know how to pop up this authentication window on the client side when he requsts for the service.
Its almost like a SQUID where the pop up box appears.

"ORA-03113: end-of-file on communication channel error" in client side

Problem Description: we have a production server that oracle 11gr2 installed and oracle clients (application servers) with 11gr2 clients. Sometimes we encounter internal server error 500 at the application server side; and when we check out the application server logs we see ORA-03113 error code.
when we look at the corresponding error on the Oracle Database Server side we saw the following output in the alert_orcl.log :

what could be the problem or how can i trace it in order to determine the exact problem? is there any parameter that i need to adjust in client side to ensure that every connection reaches the production server ?

There is often an ORA-0600 or ORA-7445 behind these.
These should produce an entry in the alert log and an associated trace file which a) can be used in the ORA-600/7445 lookup tool on Metalink and also uploaded to Oracle Support.

A bit quick to answer - I didn't see the large section of TNS information from the alert log.

Can we create export dump files on client side??

Hi,
Please see this link
http://download-uk.oracle.com/docs/cd/B19306_01/server.102/b14215/dp_overview.htm#i1010293
Check the "NOTE" which says that
All Data Pump Export and Import processing, including the reading and writing of dump files, is done on the system (server) selected by the specified database connect string. This means that, for nonprivileged users, the database administrator (DBA) must create directory objects for the Data Pump files that are read and written on that server file system. For privileged users, a default directory object is available
So does this mean, the dump files can be created only on the server???
What if i want to create the dump file on my client c:\
Is it possible??
As per my knowledge, this was possible in 9i
Thanks

Yes in the "orignal" export ,it was possible to have a client side dump file.But the Export DataPump uses the Directory parameter which maps to a directory on the server side only and the option to give an absolute path for the dump file on the client side is removed,the files can be only on server side.

Is XML-SQL Utility for Java run on Client Side?

A question about the XML-SQL Utility for Java
When a client program connect to a Oracle database (the clinet program and Oracle DB is run on two different machine. Oracle 8i is used) and use the oracle.xml.sql.query.OracleXMLQuery Class (form the XSU) to generate XML by given a SQL query. I want to know the transforation process is execute in the Clinet side or the database?
Is there any method that i can retrieve the XML directly from the database rather then doing the transformation form the Client side?

RUN form FMX from the client side

Hii
I have installed oracle forms developer 10g, i have designed simple form and i run it from the local mechine it worked, and i want to try to connect it from the client side, it didn't work
Can you help on this please

No you don't need to have an iAS to test this
Start your OC4J instance on your host
copy the file default.env to test.env (located in <oracle_home>/forms/server)
in test.env modify your forms_path to the pathe where your form is residing.
modify your formsweb.cfg file (located in <oracle_home>/forms/server)
add a named config at the end of the file (copy the example and modify to your needs)
looking like
[test]
envfile=test.env
form=test.fmx
userid=.../..@... (or you can leave this out and then you get an authentication pop up)
leave the other stuff default
now call on your other client
htpp://<your machine where oc4j is running>:8889/forms/frmservlet?config=test
if you still have troubles with your fields check wheter you have other java clients installed (I experienced also problems when other JVM's were installed with certain Jinitiator)
If so you can bypass this by making JRE the standard instead of Jinitiator
put in your named config
IE=native
and change
baseHTMLjinitiator=webutiljinit.htm
baseHTMLie=webutiljpi.htm
into
baseHTMLjinitiator=webutiljpi.htm
baseHTMLie=webutiljpi.htm
Now you will load sun's JRE instead of Jinit
Hope this helps

Why does IE8 running on XP and Win7 Virtual Machine deletes the history while I'm still browsing the same site with client-side hashbang routing?

Hello,
I have a asp.net mvc 5 web application running on .net 4.5 hosted on my local windows 8 machine on macbook pro using parallels. I'm running Internet Explorer 8 Version: 8.0.6001.18702 running on XP and Version: 8.0.7601.17514 running on Windows 7 Enterprise.
I've got both of the virtual machine source from www.modern.ie
My web application is attempting to provide single page user experience by having some client-side routing by using '#!/xxx' hashbangs in the url so that I can get and post via ajax and change the hash in the url without causing the page to reload. My
code works fine in IE9+ and other modern browsers.
However, I'm facing this strange issue in both of the IE8 versions. When running my demo app in IE8, I can login, view home page and can navigate from this home page to many details page. From the very first login page, all the pages are the result
of form's post action via ajax which then expects html from server and loads in the DOM. The page structure of my app is like summary form => Details page (can also contain summary forms) => Details...so on.
The above process works fine for few of the navigation steps. If I keep navigating from one page to another & go back, I have observed that the browser back button is removing the history items slowly. And a time comes when it totally forgets about
all the history pages that I visited to reach this current page I'm viewing!! It treats like I have just started my browsing session and this current page is the first page I've landed on with no back option. Now if I again try to navigate, I have encountered
problems like both the back and forward buttons gets disabled.
Hope, my words above is clear enough to explain this problem. The same application works fine in IE9+ and other browsers.
Till now, I have tried following steps on both VMs:
Resetting IE8.
Increasing disk space to 1024mb for temporary internet files storage.
Setting 'Never' for Check for newer versions of stored pages.
Disabling the automatic crash recovery feature didn't helped in this case. Found this on support website.
Deleted temporary files, history, cache, etc many a times.
Search many forums, posted question on StackOverflow, ASP.NET
Forums - but didn't helped.
Tried 'beforeunload' event of browser to see if any of the page is reloading because of submit or any other reason. But the page doesn't reload at all.
The issue is browser forgets about the browsing history while I'm still browsing the same site.
Is there any possible fix for the issue above? Does IE8 have any issues as many ajax form post is happening on every page?

I have really tried many things to identify any possible reason of the issue above. Even rewrote all my javascript navigation code and checked server-side code.
But the only place where I got the solution is at site: http://www.enhanceie.com/ie/bugs.asp which states that there is a bug in IE8 which reads like:
IE0012: IE Travellog broken when navigating back/away from a page with
a large POST form If there is a form input field with a value longer
than 523,659 characters, when you navigate away from the page, IE may
clear the current session's travellog (similar to history), disabling
the back and forward buttons. Repros in IE6 & IE7.
There are following solutions that you can go for:
- Check for the input field that has lots of characters as mentioned above and solve your problem.
- If you have control over the system where IE8 will be used, you can add the following registry key on that machine. There is no existing key, so, you need to add a new one:
[HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\TravelLog] "MaxSize"=dword:ffffffff
I am really relaxed to find this information as I spent really long time to solve this issue. Hope this will help someone.
