Issues with accessing forms applications behind a firewall & caching proxy

We have web enabled an forms application and has the following set-up at server end.
Machine no 1. Oracle Forms Server 6i with patch level 1 listening on HTTP/Port 80 on a windows NT box.
Machine no 2. Apache Webserver. listening on HTTP/Port 80
Both the machines are behind a firewall which allows only HTTP on port 80.
At clients end we have
1. a firewall which allows only HTTP on port 80.
2. a caching proxy server
The client machine connects through the caching proxy server.
When the client connects the applet gets downloaded and initialised, the form server log shows the following
-Forms Server Log-----
[09/27/00 15:01:09 India Standard Time]::LISTN: Connection Request [ConnId=13, Addr=194.120.163.251:16278]
[09/27/00 15:01:09 India Standard Time]::RUNFORM Client Connected [ConnId=13, PID=188]
at the same time at the client side we get a FRM-92050 error: Failed to connect to server fs.formserver.com:80
Please help
Thanks

Thanks Henrique.
This is not very promising but it confirms there is a potential issue
How did you manage to solve the problem, allowing the NW server/application to perform direct accesses?

Unifiers for drag & relate with oracle forms application

Hi All,
Is it possible to do drag & relate functionality in the portal with oracle forms application?? Is there any unifiers already available for drag & relate functionality with oracle forms application ?? If yes, then can anyone share the information.

Moses

Hi Moses, you can use D&R with querys in Oracle using query iviews.
You can find a lot of information in:https://www.sdn.sap.com/sdn/ep.sdn?page=unification_welcome.htm

Issues with accessing HD on Time Capsule

I have a Windows 7 32 bit machine that I just built. I have a Windows XP system and a Mac Book Pro running Snow leopard. My XP and Mac are able to access the HD of my Time Capsule. My Windows 7 is having issues logging into the Time Capsule HD. When trying to log into the base station using the Airport Base Station Utility I get a message stating "Unknown user, incorrect password, or login is disabled. Please retypre the login information or contact the disk's administrator (86)." I have the AirPort Utility installed on my Windows 7 and am able to log into the settings to modify the settings of the Time Capsule. Does anyone have any insight as to how to assist me?

Note: Mac 3 had a single user on it, my son. He was the admin. I created a new non-admin acct and moved all his stuff there (Not sure I did it the right way so it took a long time.). Now I am admin on that Mac. Not sure if that is relevant here (leading to the problem identified above) but thought I would mention it.
Thanks in advance for your help.
The fact that you cannot access the backup now only on this Mac does suggest this is part of the issue. Did you do this before or after the issue with access?
Permissions can be pretty tricky things.. certainly to do backups or to retrieve them from an existing backup created with different user permissions might be a mess.. Pondini is perhaps the only one who can tell you the ins and outs of that.
On the more general note.. lots of people are having issues with USB drive on the TC from Lion.. for many it stops working forever the moment the disk spins down from a reboot.. making it useless.
But it is dog slow for everyone.. The reality is USB is less than half its native speed on the TC cf on the computer.. and it wasn't that fast to begin with.
Plug the hard drive directly into the computer and mount the sparsebundle and see if the TM then can access it.. but you might need to use your admin login not your son's.
Personally if the TC disk is not big enough.. replace the TC with a larger disk version.. or the disk in the present one.. do not use disks hanging off TC. It has enough reliability issues without adding to them.

Accessing HTMLDB application outside of firewall....

If I develop an HTMLDB application on my database server that is inside my corporate firewall, how do I have people outside the firewall access it. Do I need to open one or more ports on the firewall? Using the same situation, is it possible to access this application externally from a Portal page?
Thanks,
Brett

As already mentioned this issue is not really an Apex issue, but an issue between your webserver ports and your InfoSec firewall folks. You also want to consider whether the data is sensitive enough to warrant HTTPS with SSL encrypted traffic rather than straight HTTP. At our institution we generally require HTTPS for corporate data but since the encryption requires a lot of processing it affects your application server performance. We have gone to a BigIP switch for all our HTTPS public ports, then from BIgIP to the app server we are behind the firewall and run http. So the Public Portal URL is https to the BigIP which then negotiates with the App servers. Our Network BigIP engineer works out the fiewall rules with our InfoSec folks. This approach offloads all the encryption processing to a dedicated hardware switch rather than to the app server. BigIp also allows for additional rules that can be set up to force certain URLs to require a VPN, for example.

Issue with Custom Form opening in Oracle apps

Hello,
I am not sure if this is correct place for this question.
Hi,
I have created a custom form and tested in forms 6i. I have moved the fmb and fmx files from my local machine to unix box and registered the form in oracle apps (11.5.10).
However, when I open the form from oracle apps, form opens OK but some of the field in form are blacked out-I am able to see the field but its black in color. When I type in field and highlight it with my mouse, the value I typed shows up.
What can be issue here?
I moved both fmb and fmx from my local machine to UNIX box.
Please help...

NV,
Have you resolved your issue? I've run into this before. I failed to subclass all of my objects properly from the APPSTAND.fmb in accordance with the [Oracle Applications Developers Guide | http://download.oracle.com/docs/cd/B25516_18/current/acrobat/115devg.pdf]. If you have your items subclassed correctly, double check to make sure your Forms Builder is using the correct color pallet.
Hope this helps.
Craig...

Data Integration issue with Adobe form

Hi,
We have been using many xACF forms in our WebDynpro java based application.
For one of the xACF adobe form sometimes I'm not getting the data from adobe form to webdynpro context.
Anyone can pls tell what may be the problem other then binding because that part i have already checked and it's working fine in some of the PC.
Regards
Ravindra Singh

Hi Chintan,
thanks for your reply.
I tried that part already by converting xACF form to ZCI but facing issues with the drop-downs.
Actually some of the dropdowns have values more than 1000. The value help for these drop downs comes as pop up in case of ZCI forms and the mazer problem is that in offline scenario doesn't even shows values for such dropdowns as a pop up or normal drop down.
As per the SAP Note 1013227 we are using the enumerated type of drop downs for such larger values but no help in offline scenario. I tried by changing the parameter value in visual admin as suggested in sap note which prevents pop-up for lager values but it's not recommended by SAP. Only because of this issue we are not able to migrate from xACF to ZCI.
Do you have any idea how to get values for such drop downs in offline scenario.
Thanks & Regards
Ravindra Singh

Big Issue with access applicationwise using SSO (windows AD)

Hello BO Guru's,
I have one big issue. i will try to explain my scenario here in brief.
Scenario
Currently we have 3 application A,B & C in production and SSO is configured using windows AD auth
application -> User group -> Access -> Win AD group
A | UG1 | Infoview | WD1
B | UG2 | Infoview | WD2
C | UG3 | WebIntl | WD3
Here Infovew acces refers to: View objects & refresh object of applicationwise.
WebI refers infoview access in addition to that copy document from corporate to personal folder\ category and scheduling access.
Note: corporate Folder\category & universe\connection right given appropriately.
Issue
Suppose user a belong to WD1 means wuld have access to application A with infoview access. now after some time i.e. 2-3 days when user a is deleted from WD1 and and added to WD3 means would have access to application C with WEbi access. But issue is
When user a logs on to infoview sometimes appllication A is also visible along with application C which is not correct securitywise.
Could you please help me as how resolve it? and please share your views if anybody has faced same prob before
I think some where userwise security setting will be stored causing same.
Thanks & Regards

Many Thanks Julian Jimenez,
FYI, I am on BOXI R3.1 with FP1.8
I dont have access to SIA to restart CMS.
any i will get it done.
But what i was thinking of, there would be some cache maintned for user profiles of last logins. so it may remember last user profile login which may causing apllication A still shown under corporate folder for him\her.
But i am not able to get how can i achieve it?
Please share some workaround if any body has faced same issue before.
Thanks & Regards

Full craw issue with specific web application

We are using SharePoint 2013 Enterprise (15.0.4569.1000). We have public facing (publishing site) with anonymous access enabled on it. While crawling this site we are using default Content Source called "Local SharePoint sites" where we have following
settings.
Start Addresses - http://SP2013APPSRV
Crawl Settings - Crawl everything under the hostname for each start address
Crawl Schedules - Enable Incremental Crawls
With this configuration we try to perform Full Crawl of this content source. the status of this content source goes to "Starting" then to "Crawling Full" and after some time then to "Idle" state. The overall crawl duration never
goes beyond 3-4 minutes. With this if we check the "Crawl Log" screen then except for "Successes" = 1 every other column shows 0 even the "Errors" or "Top Level Errors" column shows no record. Getting into the Success
items we found that the crawling was only done for the single item which is nothing but the start address that was specified into the content source settings (http://sp2013appsrv). Because of this it seems the crawling is not working correctly to pull all
the sub contents of the given host URl, instead it only pulls the top level link. There is nothing helpful in Verbose - ULS logs or event viewer either.
With further analysis of this we found that this issue only exists with single web application only. Because adding another web application URL into the same Content Source does crawls all the contents properly of that web application but still shows single
index item for problematic web application.
Could someone please help us with this issue ?

Hi Ajay,
Based on your description, you have some problems in doing full crawl of a specify web application.
1. Check if the crawl account has 'full read' access to affected web application.
2. Check if allow this site to appear in search results in the search and offline availability in the site setting.
3. Check if you have
opened the urlMappings in SharePoint that will hinder the search function crawls. If you add the code as below into the web.config to open the
urlMappings, it will not crawl the web application.
<urlMappings
enabled="true">
<clear
/>
<add
url="~/Home.aspx"
mappedUrl="~/Default.aspx?tab=home"
/>
<remove
url="~/Home2.aspx"
/>
</urlMappings>
4. Try to reset your search index and then do a full crawl.
The article gives you the details about how to reset your search index.
Best regards,

Issue while accessing Hyperion Applications

Hi,

Did you register the Essbase application with Shared Service, do the following steps:
(EAS) console. Right click on the application name and select 'Register'.
application successfully registered. Log on to Shared Services and select the application to assign access control.
If the error is occurring with all Essbase applications, you can register all of them at one time:
Click 'Register all'. Confirm that all applications were successfully registered. Log on to Shared Services and try assign access control for all applications.
If the re-registration does not work from EAS you may need to reregister Essbase as a product.
Locate the product_config_#.xml in the directory EPM_ORACLE_INSTANCE/config/foundation/11.1.2.0/product/product_name
For example; the Essbase product file is located in EPM_ORACLE_INSTANCE/config/foundation/11.1.2.0/product/Essbaseserver/11.1.2.0
Open the file product_config_#.xml and locate the line:
<property_name>="hubRegistration">Configured</property>
Change the status from Configured to Pending.
Rerun 'startconfigtool.bat' or 'startconfigtool.sh' or the EPM System Configurator again and select the product. This enables you to reregister the product with Shared Services.
Now check with ur ULS

Performance issue with Adobe forms

Dear SAP Experts,
We have the following issue/requirement from our client. The client is on SAP ECC 6.0 - production environment.
The client is highlighting performance issue while accessing the adobe forms for HR and FI business process ( both static and interactive ).
                Examples are
    FI – Invoice Approvals
                HR – Job Salary Change
The client is asking us to provide best practices surrounding:
1.       How to improve the performance of the adobe forms while accessing in SAP.
2.       Is there any other technology which we can use in SAP to replace the adobe forms which has better performance factor.
3.       Are there solutions such as webdynpro floor plan manager, UI Fiori which can be alternately used?
Regards,
Sakthi

Hello Priya,
     Adobe forms are easy to develop and much more comfortable than SAP Scripts and Smartforms. Initially they are a bit difficult but once you have your hands on, they are the most simplest things in ABAP.
Performance in Adobe forms is a mix of both fine tuning the Layout as well as back end coding.
Performance in Adobe forms cannot be done overnight. A lot of care has to be taken during the initial stage of development.
As far as my experience is concerned, please consider the below points while developing SAP Adobe forms.
1) Avoid Scripting (Javascript/Formcalc) as much as possible inside the form. It drastically reduces the performance and makes the form to execute slower. If you still want to use scripting(which cannot be avoided for some requirements), use Formcalc since it is comparatively faster than JavaScript.
2) Try to avoid the coding inside the Form Interface. You can always handle the maximum coding in the Driver program and pass it to the form.
3) Use Form Caching.
For forms that have fixed layout, its a good way to increase the performance of form rendering. In the layout, go to Form Properties. Then Click on Defaults tab and select Allow Form Rendering To Be Cached On Server. Then Click OK.
For forms that have flowable or dynamic layout, render the forms on the client side because it improves performance.
Last but not the least, please go through the below post by Otto Gold which is worth a read at least once.

Issues with Apple's Application Loader

I have been having some issues delivering my ePub to iBooks through Apple's Application Loader device. I've contacted Adobe, who says my file is fine. Then Apple, who says there is an issue with my file. Then back to Adobe, who says their help ends with inDesign. Then back to Apple, who says I have to talk to Adobe.
Ever since kicking us publishers off Adobe DPS, I have been having unanswered issues with producing iBooks, which is the way that we have to produce inDesign files now. Namely, I get an issue saying an image, that isn't in my inDesign file, is too big to upload to Application Loader.
Has anyone had similar issues? Please help?

Issue with Adobe Form Layout

Hi,
I have an issue with the Adobe Form Layout.Although I have added a field in the Context Menu of the Form Builder but the context has not been added to the Data View.
Could you please help me to understand how to include the parameters and structures that we define in the context and add them to the Data View in layout?As far as I know, it is done automatically.But in this case I don't understand what the problem is.
Please help me.
Thanks,
Sandeep.
<MOVED BY MODERATOR TO THE CORRECT FORUM>
Edited by: Alvaro Tejada Galindo on Jul 14, 2009 4:10 PM

it is normally done automatically. Do ANY of your fields show in your DATA VIEW? Or, are you just missing the new one?
If you're only missing the new one, make sure your Context has the field defined correctly and generated.. Then make sure you have updated the mapping in your View Context and generated that.
After those 2 things, your field should now show.
You cannot, as far as I know, define an attribute as any sort of TABLE - we have a common structure that has several Table Types in it. When we import that structure, we have to delete those attributes and create Nodes to mimick those tables.
If you've accidentally included a Table type as an attribute, you won't see any fields in your Data View.
EDIT: by the way, there's an Adobe Interactive Forms Forum where you should ask these kinds of questions.

Issue with : Stateful BSP Applications: New State Management Option

Reference:weblog by Thomas Jung - /people/thomas.jung3/blog/2004/11/09/updated-stateful-bsp-applications-new-state-management-option
I see a comment by one user to send the complete code... I am not sure what else can be sent - try it out rather than getting spoon-fed. - getting offline - sorry...
I had two issues with this ITSM way of session handling.
First - if you are using an SP42 environment, check CL_BSP_RUNTIME=>ON_SESSION_CMD() to see if CANCEL is defined as an option. If not make sure that you use &sap-sessioncmd=CLOSE" instead of the &sap-sessioncmd=CANCEL" . If CANCEL is not defined , it will give you shortdumps...
Second - when I closed the window, the session was not terminated. I used onbeforeUnLoad="exitBSPApplication(); instead of onUnLoad="exitBSPApplication(); and it worked fine. Not sure if it has any other issues.
But now I am facing a new issue... all but one application is not ending... I have no clue on why this is happening.. I am still checking..
Thanks Thomas, you are the best, as always...

Thanks for checking the code in your system.
After some investigation, I found the behavior as explained below.
If the actual url has any fields passed as parameters, e.g.. /default.htm?var1=a&var2=2 ...
- if I use CANCEL as the option, a shortdump is created and the session is not closed. if I use CLOSE, Session is terminated and no shortdump happens.
If the actual url does not have any parameters, e.g.. /default.htm ...
- CANCEL does the work, but CLOSE does not exit the session.
In my applications I used request->get_form_fields to see if there are any parameters, and if there are, then I use CLOSE as the option and else, I use CANCEL. So now, the session
management works beautifully...
There is a good chance that I am doing something wrong here too.

QSIG issue with accessing a Voice System on a Meridian

I have a Voice Gateway (2551) connecting a Meridian with the Cisco IP Telephony setup. The Callmanager is connected with QSIG to the Meridian.
Basic call feature work fine. But i do have problems with accessing the Voicemail System on the meridian. Accessing the own Voicemailbox is also fine.(Accessing from 1111 on the Voice System (5959) the Voicebox of 1111) If i now forward the calls on 1111 to the Voice System and i make a call from 2222 to 1111 i will get to the voicemail system but not to the voicebox of 1111. Seams to me that the Voice System needs more information about 1111. On the QSIG Trunk i am sending the 1111 as the redirecting number along. Does somebody expirience such issues?
Are there settings to change on the callmanager or on the meridian side? Also the MWI works fine.
Thanks for any help on this issue. Regards
Roger

Hi,
i do not know about the batches on the meridian side but i could find it out. i am only responsible for the cisco ip telefony side and i do not really know the meridian side. i'm working together with a technician who is doing the meridian side.
How can i find out which batches are needed and what is the impact to install them?
And what did you mean with little flaky...is it not supporting qsig the way it should?
Regards
Roger

F4 help issue with Webdynpro ABAP application

Hi,
I am facing a strange issue with the F4 help in my webdynpro abap application.
I have few fields for Purchase Order and Line item on the screen and they have corresponding F4 helps associated with them.
When i select for F4 help, sometimes the screen simply blanks out and a white screen is displayed. When i refresh the screen and try the same scenario again, i can see the value list correctly.
This issue occurs very randomly with no specific pattern. If anyone else has faced this issue earlier, kindly let me know how to get rid of this issue.
Any pointers to resolve this issue will be helpful.
Note: I am using SAP version 702 SP09.
Thanks,
Ramanath

Hi,
we cannot help you from offline, you need to check the standard procedures like
SICF->is your application node is active.
FQDN->check fully qualified name is configured
You can also try to execute standard SAP application, if sap application also has problem running then you may have to get the help of BASiS people to look into that and raise a support ticket.
If sap applications are running and your custom developed applications are not running then look into this application if there is any URL parameters need to supply etc.
