Migrating Access DB to Oracle Hosted APEX environment

I was wondering if there was a way to migrate an Access DB to the Oracle Hosted APEX environment using the Oracle Migration Workbench? You have to specify the location of the DB and schema and I don't know this information since the DB location is on the Oracle Hosted site. I would like to evaluate the migration functionality of the APEX tool without having to download it locally along with Oracle 10G. Is there a way to do this using the Hosted website?
Thanks!

The quick answer to this is no.
However, there are some services (http://www.appshosting.com) which do offer that type of access at no charge.
Thanks,

How to recreate APEX environment

I posted recently about best practices for prod / dev environments with APEX, and this grows from that. I have reviewed the suggested solutions with developers and met with some, shall we say, resistance. So, here is what they want to do. Please help me understand whether it's possible, and how I might accomplish it.
Our test/development server contains APEX 4.2 and Banner (our ERP) data, all in a database called DALY11G.
Developers want to to develop daily on this server, and they need current data in order to do so.
I recreate this database nightly via RMAN duplicate, and so the entire database is dropped, and recreated from production backups.
They want me to export the APEX environment nightly, before I drop and re-clone the DALY11G database, thus preserving any development they've done during the day. Then, after the clone (RMAN duplicate) process runs, they want the APEX environment dropped and reimported from that previous night's export. Once this is done they will have the up to date data they want, along with the in process development that they don't want to lose nightly.
I realize the supported method for doing this sort of thing is to export the apps and reimport them through the GUI development tool, but my users refuse this method, saying it will add too much time to their work load.
SO... is what they ask possible? And if so, how might I accomplish it? I have tried exporting (before the DALY11G database gets re-cloned) the APEX_040200, APEX_DOC, APEX_WORK, APEX_DATA, and APEX_READONLY schemas (I realize some of those are specific to us). After the clone, then, I drop the production versions of those schemas, recreate them, and then import from the exported file. But the exports throw errors, and I end up with invalid objects. Is the means of importing / exporting the entire 4.2 environment like this documented somewhere? I've been unable to locate it.
Thanks for any advice. And if you have any suggestions for how I can convince the developers to export / import their apps through the GUI, let me know that, too!
Regards,
Bill Johnson

Hi Bill,
I've never known an example of being able to move or recreate an Apex installation by exporting and importing the schemas associated with Apex. I think the relationships between schemas and objects are just too complicated for this to work easily.
I would have thought it would be easier to move the application you are developing against, but given I know nothing about Banner ERP, this may also not be an option. Also what I don't understand, given that you are trying to save any changes the developers make to their application in development, if you are refreshing the whole environment, aren't you also losing any changes the developers make at the database level. What about custom versions of DB objects they may be using for development purposes? How do you allow for this?
My preference for overcoming this would be rather than dropping the refreshed Apex environment at the schema level, but to do it at the Apex level. In order to automate this, and please you developers, there are command line options for exporting and importing applications that you can use to automate this process.
Applications can be exported through a tool Oracle supplies with the Apex download called APEXExport.class and as applications are simply sqlplus scripts, they can be imported using sqlplus command line. I haven't done this personally, but I think it would be possible.
Hope this helps.

Apex_util.get_print_Document not working outside apex environment

I am working on one of the assignment in Apex 4.0.2 .
The requirement is to dynamically generate reports and mail to User using the Scheduler program(Pl/sql) -> dbms_scheduler.
I have used BI publisher to create the template and xml data for the report(Excel) and used Apex_util.get_print_Document
in the scheduler program (which is written outside Apex), but this is not working properly,sends blank report to email.
Please suggest how to set the apex session and use Apex_util.get_print_Document to work properly outside apex env.

Apex (PL/SQL web-enabled) code needs to execute inside an Oracle server session that has been properly and correctly initialised for executing web enabled PL/SQL code.
An example of how to execute such PL/SQL by intialising a proper environment, is shown in {message:id=2251131}.
Note that this will not be able to execute Apex pages (via the flow engine) that are not public - that needs a proper authenticated Apex web session. Which could be a tad complex to emulate in this fashion.

'Sensible' Definition & Security settings for a Production APEX environment

Hi Folks.
What's the feeling on Definition and Security settings for a production APEX application?
Here are my settings for my UAT environment (not quite in production just yet)
Debugging: NO
Status: AVAILABLE
Build Status: RUN APPLICATION ONLY
Authorization Scheme : MUST NOT BE PUBLIC USER
Session State Protection: ENABLED
In the APEX Administration setup, access to my site is restricted by IP also. As a consequence I think it's buttoned down quite tightly but, eventually, we plan to open this up to the Big Bad Web!!
What are your thoughts on the pro's and con's, the why's and wherefore's of one setting or another.
I'm hoping this thread will prove to be a good forum for discussing APEX application security configurations and a reference for others.
Please feel free to link to whitepapers of relevance.
Maybe someone could take up the challenge of producing an 'UNHACKABLE' :-) APEX website?
Simon.

Hi Simon,
If you're just talking about instance settings, then you might also add to that using the 3.1 runtime only instance.
If we're opening it up to application design, well...that's a whole other matter ;)

Tasks to run your own apex-environment ?

Hi,
we are preparing to have our own apex production-environment.
the management wants to know what tasks have to be done to run such an environment.
does anyone have an overview and can we get a copy of it ?
any thoughts,comments will be appreciated, too
Leo

In an EJB environment, you have absolutely no control over threading issues. (It was purposefully designed that way.) However, you do have your own little "sandbox" in the EJB ClassLoader - which is why there is a lot of use of the Singleton pattern for factories and (very carefully!) as small caching mechanisms. You might want to look into that avenue - but you have to know how your EJB vendor's ClassLoader scheme works (there does appear to be a convergence in this area) and you must be very sensitive to potential thread-blocking operations that may take a while to complete.

How to create an HTML editor on Apex with the buttons for editing?

Hi,
I would like to have an online editor similar to the one I am using to post this thread with a bold, itallic and links button.
I see there are HTML editor items, however it doesn't have the bold, font buttons when I create the page?
Below are from the HELP section.
HTML Editor Standard - Provides more editing functionality, such as font, format and color, than HTML Editor Minimal.
Text Area with HTML Editor - Provides basic text formatting controls. Note that these controls may not work in all Web browsers.
Thanks.
Edited by: Samantha on Oct 21, 2011 2:12 PM

Hi,
Thanks. I went to the item area and did not see it after selecting 'Text area'
Only these items which do not have the cool editing features.
Textarea
Textarea (auto-height)
Textarea with Character Counter
Textarea with Character Counter & Spellcheck
Textarea with Spell Checker
HTML Editor Minimal
HTML Editor Standard
Textarea with HTML Editor (deprecated)

TNS info for internal apex environment

We are using

We are looking for TNS info for the above.
This is needed to query the DB to run SQL from any client against our schema in apex.
We are also thinking of creating a DB link to this env from our internal applications.

Best Practice for implementing dual APEX applications environment

Question:
We are in the early stages of building an APEX application for Oracle SaaS consumption. The question I wanted to ask you is what would be the best way to deploy this app for production? Would it be easier just to create a new workspace in apex.oraclecorp.com and export the app definition or create a new instance of APEX container? Also, if we were to create a new container then what are all the hardware/middleware required?
Follow up questions:
1. What are you building and for what purpose?
We are building an application for oracle employees (development, operations, and support) to assist in interacting with the CRM Saas environments. Entering bugs, tracking patch level, obtaining relevant environment contacts & urls.
2. Who will be installing this application? Oracle customers? In their own on-premise APEX instances? Oracle Cloud?
For the foreseeable future, there will only be the one internal install for internal use (CRM SaaS Enablement Team, DevOps).
3. What are the database and APEX version requirements you'll have for this application?
We do not have a particular requirement. The latest GA version would be the best candidates.
4. Is it safe to say that there is minimal understanding & experience of APEX on your team?
All we know is self-taught and from forum responses. Part of the problem we face is that we don’t know how to frame the questions in a way they can be understood.
APEX container - By this I mean a fully functional APEX environment where applications can be deployed to.
Use Case - We want to be able to make our Apex app available to the consumer (see above) and also continue to develop new features into that app for use at a later date. We are asking for information about a development model that works well for Apex apps.
Thanks!!

Moved the question to the internal Oracle forum:

Printing the data in "Textarea with HTML editor" item in APEX as pdf

Hello,
I have a requirement which goes like this.
The user enters data in the HTML editor in APEX. All the tools available in the HTML toolbar will be used (eg. bulleted points, tables etc.). This data is stored in a single cell in the database. This data needs to be generated as a pdf for printing. We have Apache FOP installed as well.
When I try to create a report region with this data and export it as pdf, the html tags are not considered. For eg. the table in the HTML editor doesn't appear as a table in the pdf, only the text appears.
Let me know if such a transformation is possible. Also, can any other tool perform this??
Note: The data in the HTML editor may not be in a fixed template. Whatever is entered there has to be converted.
Thanks in advance !!

The strip HTML attribute is set to "No" already. If you understood clearly, I need to convert the entire data in a HTML editor item to pdf. The data is stored in a single cell as HTML tags in the database. The data may inturn contain HTML tables as well. These HTML tables are not captured in the pdf, only the text within the tables are displayed.

Sys_context not working from APEX application / environment

I am struggling to retrieve a user-defined context value using sys_context(...) from APEX application / environment
I have created a global context to be used as a storage mechanism for log severity to be recorded.
CREATE OR REPLACE CONTEXT PA_LOGGER_CTX USING PA_LOGGER ACCESSED GLOBALLY;It is seeded through a function pa_logger.set_severity(1) within the package pa_logger through (excerpt):
dbms_session.set_context(c_ctx_context_label, c_ctx_severity_label, TO_CHAR(p_severity_in));
with:
c_ctx_context_label     CONSTANT NVARCHAR2(16) := 'PA_LOGGER_CTX';
c_ctx_severity_label    CONSTANT NVARCHAR2(8) := 'SEVERITY';
p_severity_in   IN PLS_INTEGERusing the following from sqlplus, other DB-tools, works as expected:
-- setting it
BEGIN
pa_logger.set_severity(2);
END;
-- displaying it
SELECT sys_context('PA_LOGGER_CTX', 'SEVERITY') FROM DUAL;returns 2
This works from different sessions, different users ... no problem.
Using it from within an APEX (accessed via embedded gateway/XE11.2 or OHS/11.2.0.2.0 ) application or even from the "SQL Commands" from the APEX Workspace returns a NULL value for :
SELECT sys_context('PA_LOGGER_CTX', 'SEVERITY') FROM DUAL;And
   SELECT value FROM GLOBAL_CONTEXT WHERE NAMESPACE='PA_LOGGER_CTX' and ATTRIBUTE = 'SEVERITY';returns the right value, which obviously defies the purpose of using the CONTEXT.
It is as well possible to set the CONTEXT to a different value, which is picked up outside APEX, but even so using sys_context does not work, always returning NULL
As a note aside: using sys_context with a standard CONTEXT, e.g. SELECT sys_context('USERENV', 'NLS_DATE_FORMAT') from DUAL works without any problems.
I guess I have a conceptual break somewhere. Does this have to do with the APEX user used, wrapping within the APEX environment, the way the context is defined ....
Any help is appreciated.
Many thanks,
- Thomas

Hi Rod,
Thanks for the time to answer. Meanwhile I found some more hints on the subject (Retrieve values from my own global context in Apex and I do now understand the concept.
I understand that I can even clear the specific CLIENT_IDENTIFIER by issuing a "dbms_session.clear_identifier()", which then subsequently works
Looking at the CLIENT_IDENTIFIER as set by APEX it is "<apex_login_user><apex_session>";
I understand it is set for every DISPLAY-SUBMIT it is reset by the APEX framework.
Hence it is not sufficient to set it for a user session; it needs to be changed for every display-submit. I can achieve this through application processes, but I am really reluctant to do so, because I do not know, if APEX relies on the CLIENT_IDENTIFIER to be set the way it is done. I suspect a purpose behind this, causing me problems elsewhere. I post this as a seprate question as this question has been answered.
On to your point about: Using a table variable. This is the way it works currently, but allegedly using the CONTEXT would give us for the logging configuration a performance gain of about 1 dimension..... but unfortunately other problems..
Thanks!

Import Schema into new (production) environment in APEX 4.2

Hello,
I am having troubles with deploying developed application into new environment. I exported application, schema and workspace and I want to import it all to a new machine. Except schema, I have imported and installed it all successfully. But after I import generated script (DDL) trough SQL Workshop->SQL Scripts I am not able to find created scheme.
Let me explain my steps in sequence:
1. I have installed XE 11g Release 2, and APEX 4.2 on the new machine (Win 7).
2. New (ghost) workspace and schema were created (named as TESTWS, TESTSCH).
3. After I logged to a new workspace (TESTWS) I completed importing old schema (DEVSCH) -( I have found that the import and install sequence should be - fist Schema, second Workspace (with mapped schema), and then Application)
4. Finally I have imported old workspace (DEVWS) trough administrator console, and have tried to assign it to old (imported) schema (DEVSCH) but without any success. I was not able to locate imported schema.
I am not sure if there is a missing step or something I have doing wrongly, so please advise what to do in order to import and recognize/locate/see imported scheme into new APEX environment?
Thank you in advance,
BR
Jasmin

No.. Once you import an application into HIGHER version of APEX, it is modified to that version.. This is a suggestion, but I would advise having some sort of version control in this case, so you can go back to a prior version easily...
Thank you,

Mapviewer SVG and Content-Type http header

Hello,
We have a Mapviewer installation that seems to be serving up the wrong Content-Type header for the SVG charts. The map is being created correctly and we can get GIF's and such.
The wrong Content-Type causes the Adobe SVG viewer to never render the SVG map successfully. When I save the SVG file to the desktop it opens perfectly or if I statically link it in to the web page from the sever it also opens perfectly. Is there some configuration that is missing somewhere on the mapviewer or the application server to correctly set the Content-Type ?
Notice the content type of the failing map compared to a working SVG chart we have.

Hello,
Thanks for the reply I've tried both SVG_URL and SVGZ_URL and used a http header sniffer to watch what's getting served up and the urls associated with MapViewer SVG are definitely getting served up with that wrong Content-Type.
Our front end is an Oracle APEX environment were we use APEX's SVG charting on the same page and they are getting served up with the correct Content-Type and display correctly, which is nice cause I can watch the header difference's side by side, and we know the mapping itself is working right because we can get image files back
Is there a sever config file or something like the httpd.conf for apache that needs to be set?
Thanks for any help or insight

Rtf Templates created with BI Publisher 11.1.1.3.0 not working in APEX

I created templates using BI Publisher v10 Desktop that I used to create Report Layouts in APEX and everything worked just fine. However, I've upgraded to BIP 11.1.1.3.0 Desktop and the rtf templates don't work. I suspect that the problem is with the graphs.
Is there something in my APEX environment that needs to be upgraded or modified to be compatible with the BIP v11 templates? Are templates created with BIP v11 compatible with APEX Reporting?

I'm having a similar issue with 11.1.1.3.0
My RTF templated uploaded to APEX correctly, and seems to load and generate ok. The OUTSIDE formatting on the report (title, etc) all seem to show fine, but the actual repeating data block doesn't show any of the data or columns or boxes..... Just the column headers.
VERY FRUSTRATING......

APEX application development with an existing data model

Dear all,
We - as a company - are trying to build an application in ApEx with an existing data model. The idea is that the data model that has all sorts of TAPIs and business rules defined is going to be re-used in an ApEx environment. I am actually wondering whether this is possible, wise, feasible. When I am building some simple pages on one specific table, which has approx. 35 fields, sometimes the triggers around that table fail. Before I am actually going to dive in to try and sort these problems I am wondering whether this use of a data model in an ApEx environment is wise.
I mean, when you build an ApEx application there are usually no triggers and TAPIs available. My logic is that the ApEx application can look after validation and stuff.
Does anybody experienced have anything smart and useful to say about this. Any feedback is appreciated.
Kind regards,
-victorbax

Hey vik,
At my company we rarely use the standard APEX wizards because of multi-linguility (on data level) and error management issues.
We always create an API in PL/SQL and call the procedures for APEX making APEX the 'view' layer in a kind of model-view-controller architecture.
The main thing to keep in mind is maintainability, if you're working with an existing datamodel with an API that works it's probably best to just created forms and reports through APEX and then calling the appropriate pl/sql (packaged) procedure manually. We believe that this kind of architecture has the downside of being a little more work initially but it's much easier to maintain large projects through a self written API and take care of issues like error handling, logging and multi-linguility through a self written API.
Kind Regards,
Geert Guldentops
