Bug APEX 4.2 Instance Settings

Hi
I upgraded my APEX instance from 4.1 to 4.2 and now I can't go to (INTERNAL) Manage Instance->Instance Settings I see only ORA-28817: PL/SQL function returned an error. :(
Who can help me ?
Regards

As with some others reporting, I got the dreaded ORA-28817 when attempting to manage the instance settings.
I upgraded from 4.1 to 4.2 a few months back. After reading some of the comments here, I tried applying the Patch Release 4.2.1.00.08 which claims to fix it - but alas - no joy - still can't manage the instance settings.
I can also get the error via the command line:
exec apex_instance_admin.set_parameter('WALLET_PWD',Null);
BEGIN apex_instance_admin.set_parameter('WALLET_PWD',Null); END;
ERROR at line 1:
ORA-28817: PL/SQL function returned an error.

Manage Workspace Instance settings in APEX Administration

I would like to change the printing settings in my workspace Instance settings. But, I can't find the "Manage Instance" option mentioned in the tutorials. Can anyone offer any guidance?

What version of APEX are you using?
This is where the printing settings are in 4.2:
1) Login as the Admin User (Internal)
2) Click on the 'Manage Instance' Icon/Tab.
3) Click on 'Instance Settings' in the Instance Settings section.
4) Scroll down to the 'Report Printing' option

BUG APEX 4.1 IR Download/Subscription

My happiness was short.
Apex 4.1 has SMTP authentication, it's fantastic news.
But when I started testing it I found that Download and Subscription Interactive Report features not working. Problem is in field "To:" This field is use to "From" variable it's a bug:
- you can't use multi adress in To field
- SMTP permanent error: 553 5.7.1 <[email protected]>: Sender address rejected: not owned by user service_user

Andy,
Yes, we are aware of To address is getting used as From. Currently multiple email address issue happens in Interactive report Email download not in subscription. We had request of defining From address in subscription, so we might let user enter in or use the instance settings. Not decided, yet. We will take a look.

Christina

Programmatically configure email instance settings

I am looking to configure the Email Instance Settings of our Production apex environment and am hoping this can be done programmatically to reduce the complexity of the pending release.
Is there an API, Procedure or Package I can call that will set the required values (Servername and Port) without having to unlock the builder, log into the INTERAL workspace and make the changes via the GUI?
Thanks for any help.
Duncs

Hi Duncs,
you may have a look into the APEX Administration Guide concerning managing runtime environments, especially section "Configuring Email in a Runtime Environment".
http://download.oracle.com/docs/cd/E17556_01/doc/admin.40/e15521/adm_mg_service_set.htm#BEJBCEEH
The above link is for APEX 4.0. If you use an older version of APEX, use the corresponding document.
-Udo
P.S.: I just found a little doc-bug. The documentation refers to
BEGIN
APEX_INSTANCE_ADMIN.GET_PARAMETER(PARAMETER_NAME, PARAMETER_VALUE);
END;where of the call should be
BEGIN
APEX_INSTANCE_ADMIN.SET_PARAMETER(PARAMETER_NAME, PARAMETER_VALUE);
END;Parameters SMTP_FROM, SMTP_HOST_ADDRESS and SMTP_HOST_PORT appear to be correct.

Instance Settings: Wallet path and wallet password

What is the purpose of the wallet settings in the instance settings for apex if you are using the modplsql instead of the XDB http server. Do you still need to set the wallet if you are doing ssl and the oracle app server with modplsql.

Am I understanding correctly that if I select "Replace the default Microsoft template" in my GPO that ONLY my custom templates will be used? This means that, for instance, the IE settings that are available out of the
box will not be captured?
It will use all of the templates in the settings template catalog only. The local copies that are installed by the agent will be deleted. This setting must be used with the configuration setting parameter ‘RegisterMSTemplates’ set to true. Please see the
section titled ‘Replace the inbox Microsoft Templates’ in the TechNet article ‘Planning for Custom Template Deployment for Desktop Applications in UE-V 2.0’.
If that's the case how do I use a template such as this one from the template gallery that says, "To use it just delete or move the original DesktopSettings.xml from your Location Template store and copy EnhancedWorkSpace.xml
to the store location."
The creator of that template states that ‘I just mentioned to disable the DesktopSettings.xml template because my template already includes the Default values from that template.’
In the Q&A section of that template
Would it be better to just remove all the default templates and use only the ones I need? Where would I get a copy of the default ones so I can put them in my settings template path if I want to use them?
When you install the agent on a client, the default templates are stored in the
install\templates directory. The default is c:\program files\Microsoft User Experience Virtualization\Templates. You can copy these to the settings template catalog location to use them even with the above settings. Note: Once you
set the GP to replace the default Microsoft templates, the default templates on the clients are deleted. If you have this setting turned on, you may need to install to a machine that is not governed by this GP setting in order to get the default templates.
Hope this helps,

2 Bugs - Apex 4 - Websheets & Query Builder

Hello,
Just to make someone from the Apex Dev team aware if they aren't already.
I've come across what i think is a bug in Websheets where if you create a data grid or interactive report and then save a Named Copy of the report (so that the select list appears at the top of the report/grid with the saved report names). When you then click on any of the drop down menus like Actions, Manage, or any of the drop down tabs at the top of the page (Page, Data, Annotations, Administration) the background of the menu goes transparent making it really difficult to read the options in the menu if there is some text behind it.
If you then delete the saved report so that you just have the one version, and refresh the page the problem dissapears. I've only found this issue when using Internet Explorer 8 (not sure about earlier versions), as far as I am aware this doesn't happen in Firefox or Chrome.
Also if you log into Apex using Google Chrome and go to the Query Builder under SQL Workshop. If you click and add a table with quite a few columns (10 or more) the scroll bar is missing down the right hand side which means there is no way to select/view all of the columns in that table.
Thanks.

Better make that 3 bugs.
Create a data grid from spreadsheet data. There must be a very small limit on the data you can actually upload using this thing, I just tried to upload 50 rows of data containing 12 columns (not exactly a massive amount). The data is a fictional list of employees, I have pasted the tab delimited data below.
It fails, but rather than giving an error message like "Too Much Data" it just clears out the text area and says "Data Must Be Provided". Also it doesn't seem to say anywhere what the limit on pasted data is.
I'd really appreciate it if somebody could respond to this ticket to let me know that these issues have been acknowledged.
Thanks.

Two APEXs on one Instance

We have a requirement to be able to have two copies of APEX running on the same Oracle instance, one available inside the firewall and the other outside the firewall. Each version would be running different applications, public and private, but sharing a common database.
Currently we've worked round this by having the public applications running in their own FLOWS0200 schemas on a seperate instance connected to the data on the main instance through links and views. While this works for the simpler queries and reports, other things like the MRU updates and pre-fetches fail.
If we can't have a second copy (installed in OUTFLOWS_0200), has anyone any suggestions how we can just expose a sub-set of our apps through the firewall, while keeping everything else safe.
I would also like to be able to shut down the access to the application development side of APEX on this outside instance so no one can try and get through to internal or any of the workspaces.

Gavin,
Installing Apex more than one time per instance is not a good idea. Consider it on par with editing an Oracle Database file with vi or performing a cold backup on a running instance - it SEEMS like it works, but a catastrophe is simply waiting to occur.
Having said that, you can solve most of your problems by adding some directives to the HTTP server via mod_rewrite (http://httpd.apache.org/docs/1.3/mod/mod_rewrite.html)
This tool will let you prevent certain URLs from being called from certain places - for example, you can restrict all access to the 4000-series (Apex Developer, SQL Workshop, etc) pages by using mod_rewrite. mod_rewrite could also be used to limit which apps are allowed to run from where, based on source IP address, for example.
You may want to use a 2nd HTTP server for the internal apps, which would be unrestricted, and then the external HTTP server could be very tightly locked into only displaying certain applications no matter what. This would insulate you from IP spoofing to some degree.
Hope this helps,
- Scott -

GUI Bug / Suggestion - View Network Connection Settings

I'm currently running Windows Server Technical Preview in a VMware Workstation environment. When I click on the network icon in the system tray, and then proceed to click on "View Network Connection Settings", nothing happens. Is this
a bug?
I know in the desktop OS this opens PC Settings which doesn't exist in Server, but it makes sense for this button to link to "Network Connections" or even "Network and Sharing Center" in Server.

Enable Desktop Experience. Server with a GUI is not the full GUI, you need to enable Desktop Experience (on User Interface options), Fax Server (for Windows Fax and Scan), Server Backup, wireless, XPS Viewer and GUI for Windows Defender, to make use of
the full graphical experience. Some shortcuts and elements in the GUI make sense only after you activate thoose functions. Windows Server seems a modified version of Windows client x64, more or less, some leftovers from the client origin still remain
in the server version. Some client features are present, but turned off by default, if you want to experiment, you can enable them. Windows Server can become very close to the Windows client, if you know what to turn on.

BUG: Apex 4.0.1 form on table with report. Not passing ID correctly

I'm trying to create a form on a table with report using the wizard. I opted for a classic report page.
The edit link on the report page does not work. The link looks like this:
http://ngdwpc3:7777/pls/apex/f?p=101:15:1800428764039812::::P15_ID:#ID#
This is clearly wrong because one would expect a value to be passed and not a column name.
Looking at the generated report page I get 60 columns. This seems to be a result of the setting:
no-checked :Use Query-Specific Column Names and Validate Query
checked :Use Generic Column Names (parse query at runtime only)
The ID column in the table is mapped to COL01.
Changing the value being passed in the link columns to #COL01# results in the correct behaviour.
My guess is that the option "Use Query-Specific Column Names and Validate Query" is the correct setting for the generated report.
Rene

Yes, I guess this is a Bug.
1. When you speciify a WHERE clause in the Wozard it adds extra quotes when appending the WHERE into the Report SELECT.
I think thats the root cause, all others just follow as a consequence.
a. Because the query cannot be parse ( two single quotes) the Use Generic Column Names (parse query at runtime only) is automtacillay set
b. This leads to COL01 to COL60
c. Which is turn leads to the link not working.
I could easily recreate the scenario.
To fix it I did the following
1. Removed the extra quotes from the query
2. Selected Use Query-Specific Column Names and Validate Query and Saved
It started working correct.
I suggest you edit your Thred name add BUG at the begining so that it gets spotted by Oracle folks on the forum.

ITunes 7 Bug: iPod sets iTunes' synchronization settings!

I certainly hope this is a bug and not a feature. I have a home computer and a work computer that I use my iPod and iTunes with. I want my podcasts to automatically be copied to my iPod at home, but not at work. So at home I have the "Sync Podcasts" feature turned on, and at work I have it turned off. But the iPod changes iTunes' synchronization settings based on the synchronization settings of the copy of iTunes it was last connected to! So assuming I leave home with an iPod full of podcasts, as soon as I plug my iPod into my work computer and run iTunes, ALL MY PODCASTS ARE DELETED because the iPod turns the "Sync Podcasts" feature on, and there are no podcasts on that computer to sync. And there's no way to prevent that from happening beforehand, because the "Sync Podcasts" feature doesn't even exist until you plug the iPod in and let it do its thing. So now I'm really ticked off, and I turn "Sync Podcasts" off. When I get home and plug the iPod in and run iTunes, my Podcasts don't automatically sync anymore because the iPod has turned the "Sync Podcasts" feature off. So right now, I'm using a workaround in which I leave the "Sync Podcasts" feature off on both computers, and only turn it on temporarily when I want to sync the iPod.

An update to iTunes fixed this a while ago.

PP 2007 - line break bug - not solvable with language settings

Hi
I have somewhat the same problem with my Powerpoint 2007 as this guy:
http://www.justanswer.com/microsoft-office/67fyp-inserting-comma-causes-line-break-even-when-plenty.html
Except it doesn't only occur with a comma. When I write in a textbox or a shape (speech bubble etc), Powerpoint sometimes forces a line break in the middle of a line (not in the middle of a word) without any reason whatsoever. It occurs
out of the blue, suddenly there is a line break in the middle of a line and I can't do anything about it. It looks like it turns on word wrap in the middle of the textbox, shape or whatever I am writing in.
Part of the problem can be solved using the language settings->japanese->allow latin text to wrap in the middle of a word. When I ran this procedure, the checkbox was unchecked, and when I checked it, the line breaks disappeared,
just as I wanted. BUT: now I am stuck with the another problem, namely that powerpoint wraps the text in the middle of the word which naturally breaks the word into two at the end of each line.
The only solution to this problem is doing the language settings->japanese-trick, as far as I can see after searching the web. And if I do that, if I uncheck the Allow latin...-box I get the same problem I had in the first place,
with the line break in the middle of the line.
I hope someone can help me with this.
Kind regards

I have raised a bug on this issue and I am actively looking into it.

Bug/vulnerability in wifi security settings

Hi there. I have an iPhone 4S. On about 21 January it was suddenly unable to connect to a WiFi access point at work to which it had always been able to do. So I tried to connect it to my personal WiFi access point which I always carry and to which I have been able to do since I set it up lst year. This also failed along with my connecting to my WiFi access point at home. I then read about Apple iPhone 4S WiFi issues (some prevailing since last year in September). I then disabled security on both my personal and home WiFi access points and my iPhone was able to connect. What seems strange is that an iPhone does not have an option to setup WEP, WPA, WPA-PSK or any other WiFi security option.
Is anyone aware of iPhones WiFi security bugs which seem to exist currently. Resetting the network settings has not helped. My iOS is at version 6.0.1 and is up to date according to my iPhone.
So is Apple going to release a patch to this WiFi security issue?

Hi there
I'm wondering if the following is happening to you.
When in Acrobat, you are viewing the document differently and able to make edits. When you are opening the PDF from RoboHelp (or more accurately, the browser) you are presenting it from the PDF reader and not Acrobat. Thus you have different capabiities.
Cheers... Rick

Bug: ApEx 4.2.1 Edit All Buttons report

Following the direction in this announcement (https://forums.oracle.com/forums/ann.jspa?annID=1203), I found what appears to be a simple display bug.
When clicking on the "Edit All" icon of the buttons section of the render column of a page, the "Conditional" column of the resulting report displays HTML when it appears the column should be interpreting the HTML instead of escaping it.
If I have a way to change it myself on the user end, please advise, but I do not see that option.
Shane.

Good to hear this is already being worked on.
When we tried to work around the "Automatic detection" bug - changing the "Application Language Derived From" to "Application Preference" or "Session" - we hit issue that some page processes were not firing in translated application.

WDA Personalization bug when running multiple instances of the same WDA component

I have found an issue relative to WDA personalization that it seems to be a bug for me.
Scenario:
In my scenario, I have a Web Dynpro component A which has two usages of the same Web Dynpro Component B (USAGE1 and USAGE2).There is a WDA application APPL_A defined to fire WDA component A. I have defined a component configuration COMP_CONF1 for WDA component B and an application configuration APP_CONF1 for WDA application APPL_A. This application configuration applies the same component configuration COMP_CONF1 to both usages USAGE1 and USAGE2.
Runtime behaviour:
At runtime, I execute application APPL_A using the application configuration APP_CONF1. When I personalize something in the USAGE1 of WDA component B, the effects does not appear in USAGE2 until a page refresh is done. Obviously, as both usages uses the same component configuration at rutime the effects of personalization should be applied to both, but WDA configuration framework fails to apply the changes instantaneously to USAGE2.
Have you expermiented this behaviour? Is there any workaround for this?

APEX Web Services Proxy Settings

So I have been experimenting with Web Services and I see to have a problem whenever I go through a Proxy Server; I keep getting the error below for the same request that works when I am not using a Proxy Server.
ORA-06502: PL/SQL: numeric or value error: character string buffer too small
ORA-06512: at "APEX_040000.WWV_FLOW_WEB_SERVICES", line 959
ORA-31011: XML parsing failed
ORA-19202: Error occurred in XML processing
LPX-00202: could not open "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd" (error 101) Error at line 1I am thinking that perhaps its because the Proxy Server I am using requires authentication; however, I cannot seem to find a provision for username/password when editing the definition.
Home > Application Builder > Application > Shared Components > Edit ApplicationAny ideas?

Hi Phiri,
the web services call will be made by the database server, so authentication isn't just an issue for APEX, but you would give the host running the database server access.
APEX itself only supports the simple proxy case just to provide the basic functionality.
Depending on which web server you use to host APEX, you might be able to let that host pass your proxy attributes with the request (e.g. when using OHS, you could put the values into PlsqlCGIEnvironmentList), though I'm not sure whether they are forwarded for web service requests automatically or if you have to build your own process to extract the value from the CGI environment and add it to the web service call.
Another option could be to start building the process in your own process right away. The database has the API-package UTL_HTTP which can be used to perform the proxy authentication (utl_http.set_authentication with for_proxy => true)
Have a look on these pages:
- example for a request including proxy and authentication (with the little change to be "for proxy") http://www.oracle.com/technology/sample_code/tech/pl_sql/htdocs/x/Utl_Http_Package_Enhancements/Cr_Using_Utl_Http.htm
- a nice overview on the package methods: http://psoug.org/reference/utl_http.html
