Attach existing Schema in Apex

Sorry All,
I have to post this tread here as the link to [Apex Forum|http://forums.oracle.com/forums/forum.jsp?forum=137|Apex] is not working since weeks.
I need Oracle (sample) HR database in Apex workspace, when I requested for it (request existing schema) I got reply as The requested schema already exists. Can someone suggest me any alternate way to get it...?
Thank for reading this post

Hi damorgan ,
Thanks for the reply,
well there are lots of reasons to believe so,
1st is, I don't see the schema name in the drop down list of schema
2nd SELECT object_type, COUNT(*)
FROM dba_objects
WHERE owner = 'HR'; this SQL does not work, ORA-00942: table or view does not exist (My schema does not have dba rights)
3rdSELECT COUNT(*)
FROM all_objects
WHERE owner = 'HR'; returns
COUNT(*)
0
1 rows returned in 0.21 secondsregards

Is it posible to use existing schema in APEX??

Hi gurus,
I need to know that how i can use my existing schema table/objects in Oracle Application Express v.2.2, for ex: i want to SCOTT or HR schema tables in APEX
Is it posible ?? kindly help me...
regards
Qamar

You can request that an additional schema be added to an existing workspace, i.e. one workspace can have one or more schemas associated with it. If you're the ApEx administrator you can create the request from the workspace where you're doing your development, then login to the internal workspace and approve the request. If you don't have user credentials for the internal workspace then ask your Oracle/ApEx DBA to approve the schema request.
Use Administration>Manage Services>Request Schema to make the request. It allows you to request a new one or use an existing one.

Mapping workspaces to existing schema

I have recently installed apex and am trying to map a workspace to an existing schema. The only schemas that show up in the drop down list are BI, IX and any new schemas I have created. I would like to map the workspace to SCOTT, OE, HR etc... How do I get these schemas to show up in the drop down list.... The only related posting I could find suggested grant select on at least one of the tables to the application schema. In this case, what is the application schema? I haven't created any applications yet...
Ken Rubesh

I found a table called flows_020200.wwv_flow_restricted_schemas. I deleted the record for schema OE and now it appears in the drop down. Is there a safer way to un-restrict schemas in apex??

Add schema into APEX

Hello
I'm new in the APEX World..So I download oracleXE.exe and install it on my windows XP. All fine, I have the web admin interface and I have the HR schema enable.
I start to do some reports and so on..But
I would like now to add a existing schema of our TEST database, in order to create report on it.
I have the TNSNAMES of oracle XP filled with the alias of the TEST database.
The TEST database is: Oracle 9i (9.2) and it's hosted by server HP UX... This is an individual dedicated oracle server. So what are the steps to do so? in the doc I didn't see any tab talking about how to add a schema.
Thanks a lot in advance
Cheers

Hi
mm ok
then, if I want to manage my database TEST and not the HR sample schema, just by creating the schema into the local database and import data should be enougth, no?
When you said to use a dblink.. I don't get this because when I connect to the home page, I must LOGIN with user/password of the schema I want, after this I can create an aplication end so on...So in this case the option, if I can not attatch an external schema, should be to create and import, write?
Look at this moment I have this:
SQL> select username from dba_users;
USERNAME
SYS
SYSTEM
ANONYMOUS
HR
MDSYS
OUTLN
DIP
TSMSYS
FLOWS_FILES
CTXSYS
DBSNMP
USERNAME
FLOWS_020100
XDB
13 filas seleccionadas.
We can see the HR schema.

Add User Schema to APEX

APEX is currently setup to create objects in schema XYZ. I have some test tables I've created under my personal schema. What is the process of allowing APEX to see my personal schema via APEX.
Thanks,
Blake

Hi Blake,
you need to create a Workspace Schema Assignment.
To do this, log in at apex using Workspace INTERNAL and your admin user/password. There you go to Manage Workspaces -> Existing Workspaces -> Choose your Workspace -> Edit Schema Assignment

Creating a new schema or adding some more tables in existing schema ??

Hi All,
We have a new requirement from the client asking us to include a few new functionalities(pages--- all together a new application has to be embedded into our application) in our application. By adding these new functionalities, the number of hits to our application can be doubled.
As per the above requirement, I would like to know that whether to create a new schema or to create some new tables in the existing database for the new functionalities.
By what way, can I handle the number of requests in a better way? by creating the new schema or by creating the new tables for the new functionalities.
Also I would like like to know what kind of factors will differ between creating a new schema or creating new tables for the new functionalities in the existing schema.
FYI... We are using Cold Fusion as front-end and Oracle 9i for back-end

This the forum for Oracle's SQL Developer tool. You will get better answers in the Database - General forum.
The short answer is that from a performance point of view there will be no difference. The issues are more to do with maintenance.

How to create an database account authentication scheme in apex

Dear
I have an apex installation (embeded) on oracle 11g.
I want to create a database account authentication scheme in apex. I have seen the page with different tab like name,subsription,source,session not valid, login processing, logout URL,session cookie attributes and comments.
I want to know what are the things to be specifed on these tabs and the effects. I have gone thru the documentation 'Application Builder User’s Guide Release 4.1' , but the functionalities of these tabs are not mentioned.
Please help.
Dennis

Thanks to dear Jit
I am new to apex.
I have gone thru that documents but I couldn't find any detailed documentation about the database account authentication scheme configuration
The database account authentication scheme creation interface will show tabs like name,subsription,source,session not valid, login processing, logout URL,session cookie attributes and comments.
I want to know what are the things to be specifed on these tabs and how it will reflect in the login. The specified documentation is not giving any detail about the above mentioned tabs of authentication scheme creation iwizard.
And also I want to know how the applciation user will be mapped to the database account?
As per my understanding a database user (for each run time user) is required for to authenticate the apex run time login other than the applciation schema user (holds the objects of applicaiton)
run time user means - end user who uses the applcaition, not the developer.
Please help.

I agree with VD in that it all depends on how closely the new features ties into your existing application structure.
The second major factor to consider is since you mention "for client" is if your application has more than one client and if you will be rolliong this feature into the application for all clients. If you have multiple clients but only this one gets this feature then it may make more sense to use a second schema, but it really depends on how easy to identify and separate this feature's objects for the purpose of maintaining it through future upgrades is going to be.

Problem in mapping existing schema in SunOne8

I am trying to deploy an CMP application in Sun Java System Application Server Platform Edition 8.0.0_01 (build b08-fcs) and facing the following issues:
1. I am generating an existing oracle schema file using deploy tool. I am able to choose the schema file, but the tables are not getting populated from the schema file. (I even tried creating the jdbc datasource, but no luck).
2. I tried mapping the existing schema manually. After mapping the cmp entites to corresponding table, RED mark is shown in the Physical Tables.
When i try to deploy the Jar, deployer is throwing the below error.
Deploy action running...
Deployment failed on target localhost:4848_server : Deployment Error -- Error while running ejbc -- Fatal Error from EJB Compiler -- Caught java.lang.IllegalArgumentException while processing CMP beans for application [TestCMP]; module [D:\servers\Sun\AppServer\domains\domain1\applications\j2ee-modules\test]: null. See log for details.
!! Operation Failed !!!
Any help..... very urgent.
thanks,
Bobby.

Bobby,
The tables do not get populated from the schema file.
Basically, the captured schema is used to provide
e the persistence engine with information about the
structure of the database. I'm not exactly sure
what the IllegalArgumentException stems from, but did
you define a cmp-resource in deploytool as well. Is
there more information in the server.log than what is
provided.Thanks for your reply.
If the tables are not displayed, how can we map the tables to corresponding entity beans. As a result, the sun-cmp-mapping file is empty.
Another problem, if i manually provide the mapping file and the schema file, the tables / fields are getting displayed correctly, but "RED coloured icon is getting displayed in the Physical Tables" dropdown box in deploy Tool.
No idea what is the problem.
I have defined the cmp-resource in deployment tool, still i am getting the same error message.
sun-ejb-jar.xml

User application-id and existing schema: Enhancer doesn't work properly

I want to use JDO, but I have an existing schema and I need to use my own

Unfortunately the documentation and examples show only one thing at a
time.
Either it describes how to use an existing schema or it shows how to use
application-controlled keys.
Below I pasted a simplified example which shows my problem.
Is there something obviously wrong in my setup? Do I forget something
maybe quite simple?
Thanks for any help - I am pretty much stuck here,

Indicator on object that an attachment exist

Hi SAP Gurus,
My clients sometimes attach Doc/PDF/Xls files (scanned invoices) to documents posted in SAP using service to the object option. Its not full fledged DMS, but in one-off instances they attach files.
My question is - Is there any way (or indicator/flag) to tell that there's a file attached to a particular document (say when one goes to view a document in FB03).
Current process of clicking service to the object icon and looking for attachment list to find out whether there's any attachement to the posted doc or not is very time consuimg/painful.
Is there some easy way to put an indicator so that if a person goes to document display in FB03, he can see a flag if an attachment exists.
thanks for looking.
Nainesh

Hi,
you can call
CALL METHOD cl_gos_attachment_query=>count_for_object
    EXPORTING
      is_object = [YOUR_FI_DOC_KEY]
      ip_atta    = 'X'
      ip_note    = ''
      ip_url     = ''
      ip_arl     = ''
      ip_private = ''
    RECEIVING
      rt_stat    = lt_counter.
to get number of attachments. If you include this in some customer extensions to FB03 you can do anything with this information (e.g. display an Information message, or display an icon if transaction supports custom dynpros).
Hope that helps,
Frank

Creating user for existing schema

Hi,
A colleague of mine created a schema and now we would like to create a user with the same name. How can this be done? When I try it it says that I cannot create a duplicate schema, but dropping the old one is not an option because it's already been filled with data.
Thanks,
Michael

You can't. When you create a user, the system must automatically create a schema with the same name. This is used for certain system, temporary objects. You therefore can not have an existing schema with the same name.

Which privileges are needed to create workspace for using existing schema

Hi,
until now I always created new workspaces creating new schemas.
today I decided to use existing schemas. i created an user (default tablespace "users", with a lot of privileges (create any context, create table, etc..)
i tried to create a workspace.
now i got an error: no sufficient privileges for tablespace "users".
how to solve ?
Leo

Leo, you might try altering your site preferences using the apex_admin app so that it doesn't try to install the sample/demo applications during workspace creation. Then repeat the provisioning attempt. If it works, then you'll know the error had something to do with sample/demo app creation in the schema. If it still gives you an error we'll know that too.

Calling existing pages from Apex

Hi,
I am working on Apex as a part of my in-house applications upgrade. At present, the intranet is written on javascript and html.
Is there a way that I can call the existing forms/reports / pages from Apex. I want to achieve that I need not re-write all the logics written, but embed already existing login into Apex screens.
Any help will be much appreciated.

So, you effectively want to embed existing (presumably custom-made) reports within the apex environment - sort of like wrapping your existing intranet in an APEX front-end?
Well, for the relevant page/report, you could create an HTML region and maybe call your existing reports via ajax methods - it would require a bit of custom javascript to achieve though. Namely it would involve invoking your remote HTML page, return the resulting HTML output into your request object, then replacing the relevant elements in the DOM with this output.
I suppose if your particular reports were too fiendishly complicated to entirely re-implement in APEX, this would be the way to go, but I have a feeling that it will require a bit of work to get going properly, indeed you could also potentially lose out on some of the benefits of using APEX (or at least, you'd be stuck with this halfway house implementation forever).
Sorry to be quite general and high-level about this, but there isn't enough detail to work with.
