Workspace for java in APEX ?

Hi, am new to APEX and I got a new workspace for 10 MB and am working in SQL, PLSQL in my workspace in Apex. Also for my apex workspace I got a message that it will expire in 10 days, is that so?
Can i work in Java, as i wanted to practice Java and do a sample project. I hope Apex will be of great help in this regard. Can someone suggest me how to get a workspace for Java start my sample projects.
Thanks

APEX SSO and Load balancing: Could not determine workspace for application

We had a single HTTP Server serving APEX in a 10.2.0.2 database configured with SSO to be used by the developers. APEX has been registered as a partner application and the login url has been CA Siteminder protected so that the SM_USER details are forwarded in the header for the application to use for authorization. Everything is fine so far.
Now we have added a HTTP Server on another host and have it all set up for APEX and its pointing to the same database. APEX_ADMIN access works as normal, but applications previously using SSO now get the following error after entering the URL.
Expecting p_company or wwv_flow_company cookie to contain security group id of application owner.
Error ERR-7620 Could not determine workspace for application ().
Using HTTP Watch I find that the application is not even trying to redirect to the login page.
What is wrong here?

APEX has been registered as a partner application as described in
http://www.oracle.com/technology/products/database/application_express/howtos/sso_partner_app.html
In the meantime I found metalink document 368746.1 which describes the cause of this problem. Please read carefully what I wrote, it all works when the the new APEX web server is turned off in the server farm on the load balancer and directed through the original web server. When running regapp.sql the hostname in the listener token was using the virtual hostname. This works fine if the request comes from the original APEX server which proofs that there is nothing wrong with the installation and set up of SSO. When directing the request to the new APEX web server the APEX_ADMIN page still works only existing work spaces using SSO don't seems to work anymore resulting in a error as described in the subject.
As for metalink document 368746.1 naming the causes of this error:
- there are no duplicate entries in WWSEC_ENABLER_CONFIG_INFO$
-LISTENER_TOKEN clearly works for requests coming from the first web server
-theoretically the web server listener port could be changed from 7777, but port 80 needs to be maintained here as production is mimiced as far down as possible.
Is there some cache table which can be cleared? How is it that the flows schema (apex engine) can not find the work space when the request comes from a new web server which can however access the APEX_ADMIN pages.
anyone?

APEX log in: ERR-7621 Could not determine workspace for application (:) on application accept.

Hi All,
APEX 4.0
Sometimes, I am getting the below error when I tried to logging into APEX workspace (after giving workspace name, User name and password),
Expecting p_company or wwv_flow_company cookie to contain security group id of application owner.
Error
ERR-7621 Could not determine workspace for application (:) on application accept.
I found some threads related to this but in different way not exactly when I am getting this error.
After 2 or 3 times, this error will not come and I can able to logging into workspace.
Can anyone tell me, What is the cause for this issue??
Thanks
Lakshmi

Hi Lakshmi,
Works sometimes and fails sometimes. Hmm. Do you have a Webserver for your APEX that is accessible sometimes and not at other times?
I also had this same message. I was trying to import an APEX application when I got it. Perhaps the cause is related althought the symptoms are different.
Please see: https://forums.oracle.com/message/11096438

Apex 5 on PDB Not working,. works fine on Root - ERR-7620 Could not determine workspace for application (4500)

Hello All,
I recently installed Oracle 12c and Apex 5 on a new server.
My apex 5 install went fine. I can access it without a problem on the root on it's default port 8080.
Afterwards, I created a new pdb (cloned from pdborcl) and created a new schema.
as sysdba, I started a new Apex instance on port 8888, but when I try to access it via http://ipaddress:8888/apex/ or http://ipaddress:8888/apex/apex_admin, I get an error (See images below)
Can someone please point me in the right direction.
Should I be doing a fresh apex 5 install on the PDB? I thought that if I installed as sysdba on the cdb, the pluggable DB's would inherit apex 5. Please help
ERR-7620 Could not determine workspace for application (4500)
ORA-01403: no data found

(WORKING ON ROOT)

Hi John,
The issue you reported is the exact issue you will encounter if database patch 20618595 is not applied prior to upgrading APEX to 5.0. In addition to the opatch apply step, did you also run $ORACLE_HOME/OPatch/datapatch? When you ran that, did you ensure all pluggable databases were open after starting the database back up by issuing alter pluggable database all open?
Finally, you indicated that you installed this on a new server. Is your main interest simply to have a new 12c CDB with APEX 5.0 in it? If so, you can do the following to avoid the issue you are currently encountering.
1) Create a new 12c CDB
2) Connect as SYS as SYSDBA to CDB$ROOT and run a 4.2.5 or later version of apxremov_con.sql. If the database you created in step 1 is 12.1.0.2, you can simply use $ORACLE_HOME/apex/apxremov_con.sql
3) Connect as SYS as SYSDBA to CDB$ROOT and run apexins.sql from the 5.0 source specifying the positional parameters as you normally would

Runtime environment for the production apex instance

My first goal is to export a full application from a full development environment to a runtime environment.
The two environments are on dedicated servers.
From Oracle Application Express documentation and Oracle Application Express Forum, I realized that to install an exported application into a runtime installation, you must:
1) Export the workspace from the Application Express instance where the application was developed. The export file created contains information about the workspace, all the users in the workspace, and any groups in the workspace (if applicable).
2) Use SQL*Plus to import your workspace in to the runtime environment.
3) Export and then import your application (with Supporting Objects) using SQLPlus in to the runtime environment. The related files
This means that to be able to import an application via SQL*Plus from a development environment to a runtime environment, the workspace must exist (with the identical workspace ID) in the runtime environment. And the best way to ensure that the workspace IDs are the same is to export the workspace from the development apex instance and import it into the runtime apex instance.
Also, you can't change the application ID through SQL*Plus - so if you're importing the application via SQL*Plus, either a) that application ID can't exist, or b) if it does exist, it will be overwritten by the import (of course, in case b we don't export/import also supporting objects).
I know that there are some tricks, like editing the application export file just to import into a workspace with a different ID in the production runtime environment. But i wuold like to be official supported ;)
So in my case i think i could, for the first export/import:
1) Convert the production apex instance from runtime environment into a full development environment.
2) Export the workspace from the development instance using the apex administration services (in a text file).
3) Import the exported workspace into the production instance using the text file created and SQLPlus connect as APEX_030200.
FOR THE NEXT POINT 4 I ASSUME THAT EXPORTING/IMPORTING A WORKSPACE DOES NOT INCLUDE THE SCHEMAS ASSOCIATED WITH THE WORKSPACE.
4)
a1) Create a new schema for the supporting objects of applications in the production instance with a DBA tool.
a2) Assign the schema created in the production instance to the workspace imported from the development instance, using the apex administration services.
or, if you want apex creating the schema for the supporting objects of applications:
4)
b1) Create a new workspace (with a new schema) in the production instance using the apex administration services.
b2) Delete the workspace created in the production instance: the schema will not be removed.
b3) Assign the schema created to the workspace imported from the development instance.
5) Delete the users and eventually the groups in the imported workspace in the production instance, using the apex administration services.
6) Change the name of the imported workspace in the production instance, using the apex administration services.
7) Convert the production apex instance from full development environment to runtime environment.
8) Export the application (with supporting objects) from development instance, using the export page.
9) Import the application (with supporting objects) to the production instance using SQLPlus connect as APEX_030200.
10) Export all associated files (related files) of the application (CSS, Images, Themes, ...) from developmente instance, using the tabs located at the top of the export page.
11) Import the related files to the production instance using SQLPlus connect as APEX_030200.
So, for next the next releases of the application i can again export the full application:
1) Export the application (without supporting objects) from development instance, using the export page.
2) Import the application (without supporting objects) to the production instance using SQLPlus connect as APEX_030200.
3) Export all updated associated files (related files) of the application (CSS, Images, Themes, ...) from developmente instance, using the tabs located at the top of the export page.
4) Import the exported related files to the production instance using SQLPlus connect as APEX_030200.
or i can export and import single pages of the application.
Excuse me for the long introduction, but the question is:
what i have written is correct? Please let me know also your advice.
Thanks a lot.
Silvio

HI,
Thanks for responding.
Should the APEX_ADMIN be available in a runtime environment?
If so, we have missed a step in our installation.

Exploring AW (analytic workspace) in Java

Hello,
I am creating a java program that can retrive data from analytic workspace that is also built with java program, but I don't know how, so I have a couple of questions for those that can help me.
1. Is there anyway that I can insert data into aw dimension with java program?
2. If not how can I map existing tables within Database with analytic workspace dimension?
3. Is there any posibility to connect to aw dimension with MdmDimension class and retrive data with that class ?
4. Can anyone provide any example programs on this?
5. Can anyone provide me a simple example how to explore data within the analytic workspace in Java. I want to retrive data from aw cube or dimension if it is posible.
I appreciate any help,
Thanks

Have you considered using the BI Beans? Just a thought...
Regarding your questions, 1 and 2 are probably best addressed with the OLAP Analytic Workspace API (a.k.a. AW/XML). You might want to take a look at the Javadoc. You can find the latest Oracle OLAP documentation at the following OTN site:
http://www.oracle.com/technology/products/bi/olap/olap.html
As for the other questions, here is some help from an OLAP API developer:
3. Is there any possibility to connect to AW dimension with MdmDimension class and retrieve data with that class?
The simple answer is no. The OLAP API divides functionality into metadata and data. The Mdm and Mtm classes deal with metadata. These classes represent the relationships between AW objects. The Source and Cursor classes deal with data. They are used to define queries and retrieve data. But the getSource() method can be used on just about any Mdm object to get a Source.
4. Can anyone provide any example programs on this?
The "Developer's Guide to the OLAP API" has a lot of examples. But here's a brief example of getting the member IDs of a dimension.
// given objects
DataProvider dp;
MdmPrimaryDimension dimObj;
// we will commonly work with hierarchies rather than dimensions
MdmHierarchy hierObj = dimObj.getDefaultHierarchy();
// get the Source for the hierarchy
Source hier = hierObj.getSource();
// get a Cursor
CursorManagerSpecification cursorManagerSpec =
dp.createCursorManagerSpecification(hier);
SpecifiedCursorManager cursorManager =
dp.createCursorManager(cursorManagerSpec);
Cursor cursor = cursorManager.createCursor();
// retrieve the values
do {
System.out.println(((ValueCursor) cursor).getCurrentValue());
} while (cursor.next());
5. Can anyone provide me a simple example how to explore data within the analytic workspace in Java. I want to retrieve data from AW cube or dimension if it is possible.
The preceding is one example of exploring data from a hierarchy. Getting data from a dimension is nearly identical -- don't call getDefaultHierarchy(), and call getSource() on dimObj. Getting data from a cube is a little more involved. Again, there are excellent
examples in the documentation, but here's a brief one:
// Given objects
DataProvider dp;
TransactionProvider tp;
MdmMeasure salesObj; // dimensioned by customer and time for this example
MdmHierarchy customerHier;
MdmHierarchy timeHier;
// Get Sources
Source sales = salesObj.getSource();
Source customer = customerHier.getSource();
Source time = timeHier.getSource();
// Create the query. We must join the measure to its dimensions.
Source query = sales.join(customer).join(time);
// We have created a new Source, so we need to commit the OLAP API
transaction.
tp.prepareCurrentTransaction();
tp.commitCurrentTransaction();
// Create the Cursor. This Cursor has a more complex shape because the query is more complex.
CursorManagerSpecification cursorManagerSpec =
dp.createCursorManagerSpecification(hier);
SpecifiedCursorManager cursorManager =
dp.createCursorManager(cursorManagerSpec);
CompoundCursor cursor = (CompoundCursor) cursorManager.createCursor();
// retrieve the values
do {
Iterator iter = (cursor.getOutputs().iterator();
boolean first = true;
while (iter.hasNext()) {
if (!first)
System.out.print(", ");
System.out.print(((ValueCursor) iter.next()).getCurrentValue());
first = false;
System.out.print(": ");
System.out.println(cursor.getValueCursor().getCurrentValue());
} while (cursor.next());
Hope this is helpful.

Could not determine workspace for application... OWA_UTIL or REQUEST_CHARSE

Hello,
I have a problem with our production/test server running Oracle 10g and APEX 3.0.
Sometimes, when I try to log into APEX I get that Could not determine workspace for application... error... After few page refreshes, it works.
I had the same problem with my localhost (running Oracle 9g) and I solved it by updating OWA_UTIL to 10.1.2.0.6 from APEX 3.1 installation. I checked, and on production/test UWA_UTIL version is 10.1.2.0.0.
Another difference is in settings is:
Production/test:
REQUEST_CHARSET EE8ISO8859P2
REQUEST_IANA_CHARSET ISO-8859-2
Localhost:
REQUEST_CHARSET AL32UTF8
REQUEST_IANA_CHARSET UTF-8
What is actually causing my problems? If I would have to ask system administrator to do some changes, I would definitely like to ask him to fix all necesary things at once.
Can any change affect something else besides APEX?
Thanks a lot!
Adam

OK, so I asked our DBA to update even the DAD settings, however, sometimes the error pops up again.
What is strange is that nobody except me ever complained about this and it only appears in InternetExplorer (I never got this error in Firefox). My charset settings in explorer is "Autodetect".
So, I have definitely the correct version of OWA_UTIL and correct configuration of charset in DAD.
Any ideas what else should I check?
Thanks!

Error ERR-7621 Could not determine workspace for application (:) on applica

Hello!,
We have a simple template based report in apex, it has 2 tabs, each displays a very small, static table
(about 30 records, 3 columns each). There is 1 user accessing apex, who is logged into the db server
that has the apex app. We've tried several browsers, all same have behaviour as outlined below;
When selecting either tab, we frequently get this error;
"Error ERR-7621 Could not determine workspace for application (:) on application accept
Expecting p_company or wwv_flow_company cookie to contain security group id of application owner.
OK."
The user clicks "OK" and it takes them back to the tab they were viewing but not the one they selected
OR sometimes it displays the wonderful, "Page Cannot Be Displayed" etc.. Refreshing browser either
then displays the error message (above) or stays with "Page Cannot Be Displayed".
The environment:
Application Express 3.0.1.00.08 using PL/SQL gateway
Oracle db 11.1.0.6
Windows 2003 SP2
Browsers IE(6,7,8), Chrome, FF
Additionally APEX is very, very slow whether it errors or not and in any browser.
Any ideas where to start troubleshooting? Thanks in advance, Donald

Hi Suzi,
Have you got the fix for this error ?
I have an application in 3.2, and when migrated to Apex 4.0 I get this error. The page has Anychart xml's. When I debug using firebug console, I see the AJAX processes executing successfully. I can clearly see the Headers / Post & Response from the AJAX call. But when I view the XML I see the below error:
XML Parsing Error: not well-formed Location: moz-nullprincipal:{53b4be08-1c99-4d82-8936-a906246d86ad} Line Number 1, Column 6:

</script>Not sure if this error is due to the corrupt XML or something related to Authentication. The Production application (which is in 3.2) has an SSO authentication. Currently, we are in the process of migrating to 4.0 and our SSO has not been configured yet. I have turned off the Authentication for now part of my testing in our Dev (which is 4.0).
I made sure the Anychart libraries are setup similar to how we have in production, and they are using the same set of Anychart JS.
Can someone please help ?
Thanks!

Danny Layne

Danny,
I don't know why you get that message, probably when the engine is trying to redirect to an error page. I see that your login page has a number of after-submit processes that depend on :P101_USERNAME. These are placed after the clear process which would clear P101_USERNAME, so that's one problem. The other problem is that when you authenticate to your application as a different username from the username you use to authenticate to the development environment (the Builder, etc.), you may get a different session ID for the application that you are testing (using the Run links) as distinguished from the session you have in the Builder. This is explained in more detail here: Re: ERR-1002 on login after switching authentication to LDAP (2.2) The best place to put after-authentication logic is in the authentication scheme's post-authentication process. Just edit the authentication scheme and put your process code in there (or call a stored procedure). This process is guaranteed to run in the same session as that allocated to the user just authenticated.
The final problem to mention with putting processes on the login page (after the login process) is that they continue to run even after the "login" process redirects to the after-login page. Even if everything runs in the same session, there is no guarantee that the after-login page and its on-load events will be executed after the after-login processes on the login page.

Utilizing the Workspace for end users

Trying to see how can I utilize the existing workspace for "end users" who are supposed to access the application, I have two questions:
1- How to remove the extra regions, logos and etc.
2- How to add link to the application
Thanks,
Mehr

I'm not clear on your question, but I'm going to take a wild stab in the dark and think you would like to customise the workspace login

Why not provide them the appropriate URL in the first place?
