Forms 9i sizing metrics/ network bandwith

I have a potential customer who are evaluating Forms 9i for their intranet. Their biggest concern is the size of the Forms deployed to the client compared to JSP pages and HTML/Javascript, the size of any java classes that would need to download to the client, on-going communication between the client and app server, and any Jinitiator programs that would need to be installed as all program applications are managed by local IT teams and not the end user.
I need some ballpark facts and figures on the size of Forms and their relative % reduction in footprint in comparison with previous releases of Forms and JSPs.
Also, I need to confirm what exactly other than a browser (the customer's corp standard is IE 5.0.1) has to preinstalled on an end user's PC.

Hi Grant,
Thank you for the info thus far.
I've read through the capacity planning guide. It gives me a good indication of resource usage on the middle tier. However, what about the client?
I understand from what you have stated that the JAR files are cached once regardless of the JVM used. Is this true for JVM supplied with Internet Explorer 5.01? Will this 'older' version of the browser even have a JVM modern enough to cope with the demands of forms 9i? Or will I need JInitiator?
How big is Jinitiator if I do need to download it? 5mb, 10mb, 50mb?
What about the one off JAR file that will get cached? I heard a ball park of 8mb.
When I launch a medium form as a servlet, the capacity planning guide says approx 6.2mb per user. What is this 6.2mb? Is it an approximate .FMX file size, memory, or a combination of the two? Where is this 6.2mb allocated? Is this memory/swap space allocated on the servlet engine on the application server machine or is this 6.2mb downloaded/allocated on the client PC?
What for a typical form is downloaded to the client when I launch a Forms based application as a servlet? Is the entire Forms file downloaded after which there is only minimal traffic going back and forth between the client and middle tier. Or does the servlet act like a screen scraper (i.e., Citrix) and the already cached classes are used to render everything and the extend of the network traffic limited to rendering differences in screen appearance?
I understand that a Forms application is typically aimed for more complex interactive applications. However, if you have skills in both Web PLSQL (to render HTML and Javascript), Java and Forms, it would make sense to leverage those skills that would make you more productive. It is very quick to build a large number of screens in Forms - it would take longer coding from scratch with HTML/Javascript. The application we need to build is large in terms of the number of screens, but not too complex in terms of a demand for a high level of client side validation.
If the trade off in performance is small it would be prudent to develop in Forms if you could get the application built and live in a quarter of the man days. If the trade off is going to be significant then it would be more prudent to go down the HTML/Javascript or JSP route.
I hope this makes sense.
Cheers,
John

John please post Forms questions on the Forms discussion forum.
Anyway, What you should understand is that there is only one Java applet that runs any Form.
This applet is cached on the client - so it is a one time download. The FMX is not downloded to the client at all it remains on the server and the client only gets instructions on how to render the Form.

Forms Recognition - Sizing

Hi,
Does any one have sizing metrics for Oracle Forms Recognition? I need to know how big has to be the server to process 12k pages per month (about 600 per day).
Thanks,
Fabio

If you haven't already resolved this, you need to contact Oracle Sales to license your OFR (aka WFR) implementation. it is licensed by the processor.

Limiting network bandwith for SAP printing

We are usinge ERP 6.0 (Win / MSSQL). One of the issues we are facing is that SAP printing take too much network bandwith.
Our network bandwith between Datacenter and office is 1Mbps.
Is ther any way to limit the use of network bandwith for SAP printing. Let's say up to 30 % of bandwith is assigned to SAP printing.
Thanks.

Hi,
I am not aware of such way to "assign" bandwidth. For this reason you need to do precise network capacity planning and start the printing only when you do not have a peak of other important activities.
Best regards.

Tabular form with a metric/imperial selector

Hi,
Oracle 10g database and APEX 3.2.
I have a tabular form based on a simple query (SELECT rock_type, depth FROM rock_samples) with an editable "depth" field. The user cannot add or remove records, but can make updates to that one field. MRU process is handling that.
The underlying table "rock_samples" stores "depth" in meters.
I need to somehow allow the user to select either metric system (meters) or imperial (feet). Based on that selection the displayed deths should change. However, regardless of the selection the updated values should be saved as meters.
Any suggestions on how to implement this would be most welcome, as I cannot think of anything.
Thanks,
Constantine

Hi Constantine,
Sorry my code was slightly confusing. :P1_SELECTOR would be the name of your selector with "Metric" and "Imperial" in it, and this would have to submit the page on select. You can still use the decode in your select statement to display the initial value.
SELECT col1, col2, DECODE(:P1_SELECTOR, 'M', depth, 'I', (depth*3.2808399)) depth_result
from table_nameSaves/Inserts will be trickier. This could probably done with Javascript, but seems like it would be best handled by a trigger just before insert/update on your table. But then you need a way of knowing if the :NEW values are in Metric or Imperial, so you would need a "dummy" value or flag in your table that the incoming values are in Imperial and need converting to Metric.
Hope this helps,
Aaron

Parameter Form Fields Sizing

So here's a weird problem, and I know I've solved it before a few years ago. Basically when our reports parameter form renders the html table columns are all being sized to like 60,000, which is causing the parameter form to render as a huge website (involving lots of scrolling to get to each subsequent parameter). When running it locally or on one of our other servers its not a problem.
I vaguely remember there being a configuration file under Oracle Forms that I corrected to fix this, however I can't seem to find what I need to fix. Any help would be greatly appreciated.
Thanks

Hello,
Try to set :
REPORTS_DEFAULT_PIXEL_SIZE=80 ; export REPORTS_DEFAULT_PIXEL_SIZE
in the file reports.sh and restart the Reports Server

Could Form server use the network device

Can anyone tell me?
When i used the form server, I had to type a full nework device path on the "serverArgs" parameter because my applications are on network device.<PARAM NAME="serverArgs" VALUE="module=\\servername\device\main.fmx>
When i ran the html page on web ,it will appear the message (cannot read the form \\servername\device\main.fmx) . What can i do to fix the problem?

Try changeing the DSN server. See:

Medium sized wireless network topography help.

Hi.
I need to set up a wireless network for a three story vacation rental condominium complex. Each floor has 12 units for 36 in all. The idea is to give renters wireless access to the internet. My plan is to use an Airport Extreme to connect to the building's single cable modem and then use Airport Expresses strategically positioned around the complex to create a WDS. Will this work? Is it the best way to accomplish my goal? How many users could be connected at once?
Thanks for the help.

The limitations with WDS is that you can only have 5 wi-fi routers total. There can only be one relay router between a main router and remote router.
What is a relay router and what is a remote? Look at this "diagram":
Main router <-> RouterA <-> RouterB
RouterA is a relay router because it acts as a relay station between Main and RouterB
RouterB is a remote router.
And then check out this diagram:
Main router <-> Router1
Router1 in this case is known as a remote router also even though there is no relay.
So, you can only have 5 routers total so the largest network you can have will be in the shape of a partial star. Look at this poor diagram:
Main router <-> Router1 <-> Router2
Main router <->RouterA <-> RouterB
In the above diagram, there is really only ONE main router (but due to limitations of using ASCII drawing to make parallel diagrams, this is why there looks like two main routers). Router 1 and 2 are shooting off on their own network trunk. Router A and B are also shooting off on their own network trunk. Router1 and RouterA both connect to the SAME main router.
Also don't forget: Airport Express can at best only handle 10 clients at a time. Airport Extreme can handle 50.
This should not be a problem if your Airports are scattered adequately.
Give all of this, it is possible, I think, to use Apple's routers to form your WDS system but of course as the other reader said, depends on the construction of your building and other interferences.
HINT ON HOW TO REMOTELY RESET WDS SYSTEM
And here's my hint on how to remotely reset a WDS system using Airport Utility. You always want to work backwards from where you are connecting. So for instance, if you are connecting from RouterB, rest Router 2, then 1, then the main, then A, then finally B. If you don't do it this way, you have to keep waiting for one router to be back online before you can reset the other routers.

APEX vs Forms 6i - Processor/System/Network Overhead

We have been developing and deploying applications using Forms 6i for some years, have moved to web forms and are now developing in APEX. The IT department of client of ours has asked us to provide the relative performance merits and impact on CPU performance for each of the three technologies with particular focus on the server on which the Oracle database is running, in order to determine a basis for charging.
Assuming that the application is the same. i.e. There is a common set of PL/SQL commands across the deployment technologies. Would it be true to say that this would be relatively the same for Forms and Web Forms, since these are generally deployed with separate forms or application servers, but would be higher for APEX, since APEX PL/SQL commands are required to build web pages before being sent (in this case) to the Oracle HTTP server? If so, are there any figures available to substantiate this case?
Taking this one step further. Given that there is a network overhead for each of the deployments (in addition to the database overhead) has anyone conducted an analysis on the relative efficiencies of the three in presenting the same content? Or any insight as to what that might be? This could potentially be offset against an increase in datbase server cycles, if the former is true.
Thanks very much for your help.
Regards, Malcolm

This will be hard to quantify without running your own tests, but based on feedback from other customers, the server resources required for APEX are somewhere in the neighborhood of 1/3 to 1/10 that required for Forms. This is especially true for memory, since every Forms client requires a dedicated server connection whereas APEX uses connection pooling. So, lets say you have 1,000 Forms users with an average memory requirement of 5mb per client (just guessing here), that's 4.8gb of RAM just for client connections. The typical number of sessions in that size APEX deployment is 10-20 = 50-100mb of RAM for client connections. The CPU impact of rendering APEX pages is VERY insignificant compared to the CPU required for most of the queries your developers will write. One of the busiest internal APEX instances has over 200,000 page views per day and is a 4 processor machine.
Regarding network traffic, I'm not sure but you could measure the Forms traffic with Wireshark. You can probably estimate your average page view for an APEX to be somewhere between 35 and 50kb excluding CSS, JavaScript, and Images which should only need to load on the first page view. I highly doubt either client-server forms or web forms are less than that.

Smart forms - Dynamic sizing of the windows.

Hi gurus, iam working on smartforms, i have a problem.
My requirement is: Printing a table data on the smart form. Is the window which prints this table data is resized with the amount of table data, if so, what is the procedure i should follow for to print this data in the window.
Please give me the steps to go with the above issue. iam new to smartforms. what is the size of the window i should give in the Form painter and what all the attributes i should declare.
Plz give a detailed explanation..

What is command in Oracle form 10g to check network which using webutil?

All friend have know command to check network which using webutil then let's tell for me know, example as using client_host('cmd /c ping dantri.com').
But i don't know express. Let's me find it. Thanks you very much!

Ok,thanks you very much, because i doing a program at company, it related to server. I want to check network of this server to if ping local server is reply then will do upload data to folder on server file, if ping server is not connect then keep in C driver local. Now i not yet find solution about this problem. I hope all friend may be help me find way. Thanks you!

Why does my Macbook always ask to connect to BTOpenzone even after removing it form my wi-fi networks?

Everytime I open my Macbook to go online it automatically selects the wifi network of BTopenzone or BT Wifi with Fon. I have only ever connected to the Internet in this way once, over a year ago, and have removed it from my networks list several times and asked not to be connected in this way.
If I want to connect to my home wifi I have to join other networks and search for it there. It frustrates me every time. Does anyone have any idea why my laptop is doing this?
As you can probably tell I am not the most computer literate. Possibly this is an easy thing to rectify and I am just being naive? I hope so! Any suggestions will be gratefully received.

Hi Eric, thanks for replying. I've tried the above, deleting BTOpenZone and moving my home Wi-Fi to the top of the list but it's not working.

Network bandwith for oracle

Hi,
we should size our network (LAN and WAN) bandwidth regarding Oracle database and Oracle Applications that we will install. how to determine Bandwidth ? What is the relation between number of users, number of transactions and bandwidth ? Any Oracle documentation ? Please ?
Many thanks.

The answer is 'it depends'. It depends on which modules you have purchased, on your user distribution (geographic and role), and ...
Surely you have hired consultants who are familiar with Oracle Applications to do the implementation. They should have information based on your specific configuration and needs.
If nothing else, contact Oracle Sales - your presales consultants have access to that information as well.

'Good form' rules in designing networks

Are there some simple rules (as best practice) witch we must follow in designing LAN?
I debated with a customer’s specialist how to build LAN in his new edifice.
There is a building with the next planned desktop distribution per floor: 50, 40, 130, 50 and about 10 various servers. Customer is a bank.
Client is sure the next structure will satisfy his requirements: as core will be used 3750G-12S + 3750G-48TS (two for each for resilience). On floors there will be groups of two 3560G-48. Each group will be connected with 2 ports Etherchannel to “core”. 3560G in group will be interconnected with CAB-SFP-50CM (Catalyst 3560 SFP Interconnect Cable).
I am sure this is wrong way. But I have only intuition and theoretical arguments.
At first I think the 48:1 oversubscription on wiring closet is too much. I saw somewhere the recommended value is up to 20:1.
Next: for LAN with 250-500 workplaces Cisco recommend using Catalyst 4500 as core. 4500 Supervisors had at least 64Gbps and 48Mpps (Sup-II) and I think it is may be not enough for him. Client solution has 32GB bandwidth (3750 StackWise bus). But may be he’s right? For his 8GB all uplinks speed this is enough?
Has anybody any ideas? May be offer me any useful links, where such questions are discussed.

Take a look at the design guides. They are guide, not hard and fast rules.

Optimizing the network bandwith

So this is the problem, i have a really crappy internet connection, so crappy that while running ktorrent opening web pages is too slow. So is there a way to limit net access of some apps while others and trying to connect to the net, and the unlimit when the program has finished downloading.

I'd also like to know if there is some app in the repos that can shape outgoing bandwidth on a per-application basis and/or act as an outbound firewall (aaaaah, the vestiges of being a Windows user). Before anyone slaps me with an iptables links, iptables does NOT work on a per-application basis. (I'm not installing it, but if anyone knows a bit about the capabilities of SELinux in this regard, feel free to share some info).
piotrk: Do you know:
a) of an app that can handle QoS on Arch
b) how to configure QoS manually in Arch (i.e. on the local machine)
