How to develope application with multiple schema

Hi,
In my application, there is 3 schema, forms are from different schema, but the database is one. How should I manage it, When i open the form with different schema I am not getting the expected result,
I am using Oracle 10g Forms & Database
Thanks in advance
Rizly

hi,
what database-user is the user connected with, when executing the forms ? Is it one of the three schemaowners or has each logical user his own database-user?
About your db-objects:
I would create 3 roles, one for each schema, and grant the needed privileges for one schema to the according role
Example:
CREATE ROLE RL_SCHEMA1;
GRANT SELECT, INSERT, UPDATE, DELETE ON SCHEMA1.TABLE RO RL_SCHEMA1;
...Then you can grant the roles to the databaseuser you are connected with at runtime.
If you use named users (each logical user has it's own database-user) then you assign each user only those roles he needs.

One application with Multiple schemas- common application frame work

Hi All,
I am trying setup a common application frame work in apex. Please help me.
How to achieve this.
Creation of one application attached to different schemas at run time. So that my application maintaince is going to be easy instated of creating copies of same application.
More details:
1. I have one application with 100 pages pointing to a schema dev_common in one workspace APP_COMMON. I have 50 schemas with same structure of dev_common schema with different set of data ( because of large amount of data).
So I want to create one application attached to different schemas.
2. And another thing is I have 100 users, the user can work on 1 or multiple schemas ( I mean same application with different schemas attached)
Any help much appreciated.
Thanks,

Thank you for the reply.
>> b) I think you have to give access rights for the dev_common and app_common to all users.
Dev_common schema is a kind of placeholder. I have 50 schemas same as dev_common because of different business requirements but the front end is same for all 50 schemas. How can we create one application used for 50 schemas instead of creating 50 applications and 50 workspaces.
Please help me.

How to use one application with multiple schema without copying application?

Hi,
Previously we are using oracle forms and by that we can manage by using a set of folders containing fmx and use different schema/database for different customers. so the source code comes from one individual file but used for different database users.
is it possible to do this without copying application in apex?
reason is because if applications are copied for each customer, and in a situation where a page has a bug, the developer must correct multiple pages across all the application. This would not be appropriate to manage.
could this be done in apex? or is there any other approach?

Hi,
An application is tied to its parsing schema, so it is not possible to have one code base which you can then point to different schemas. I have seen some threads relating to dynamically setting the parsing schema, but I don't think it has worked to well, and would not be a supported configuration by Oracle.
The normal way to do this is to have one schema and for each entity where it is logical you will have an extra key which is the customer id. I mention where it is logical, because not every entity needs its own data defined by customer. Some data will be common across all customers, such as lookup data and some entities will comprise child entities by which the data separation will be implied by the parent. You can then use Oracle's Virtual Private Database feature to implement a seperate view of the data through the application, based most likely on the customer who is logged on.
Hope this helps.

Andre

Help With Multiple Schemas In Multiple Environments

Dear Oracle Forum:
We have a bit of controversy around the office and I was hoping we could get some expert input to get us on the right track.
For the purposes of this discussion, we have two machines, development and production. Currently, on each machine, we have one database with multiple schemas, say, one for sales data and another for inventory. The sales data has maybe 200 tables and the inventory has another 50. About 12 times a year, once a month, we have a release and move code from dev to prod. The database is accessed by several hundred Pro*C and Pro*Cobol programs for online transaction processing.
The problem comes up when we need to have multiple development environments. If I need to work on something for May that requires the customer address field to be 50 characters and somebody else is working on something for July that requires the customer address field to be 100 characters, we can’t both function in the same schema. We have a method of configuring running programs to attach to a given schema/database. Currently, everything connects to the same place. We were told that we should not have the programs running as the owners of the schemas for some reason so we set up additional users. The SALES schema is accessed with the connect string: SALES_USER/[email protected]. (I don’t know where we got dot world from but that is not the current discussion.)
One of the guys said that we should have 12 copies of the database running, which is kind of painful to think about in my opinion. Oracle is not a lightweight product and there are any number of ancillary processes that would have to be duplicated 12 times.
My recommendation is that we have 12 schemas each for sales and inventory with 12 users each to access them. We would have something like JAN_SALES_USER, FEB_SALES_USER, etc. Each user would have synonyms set up for each of the tables it is interested in. When my program connects as MAY_SALES_USER, I could select from the customer table and I would get my 50 character address field. When the other user connects as JUL_SALES_USER, he would get his 100 character address field. Both of us would not know anything different.
Another idea that came up is to have a logon trigger that would set the current schema for that user to the appropriate base schema. When JUL_SALES_USER logs in, the current schema would be set to JUL_SALES, etc. This would simplify things by allowing us to avoid having something like 2400 synonyms to maintain (which could be automated without too much difficulty) but it would complicate things by requiring a trigger.
There are probably other ways to go about this we have not considered as yet. Any input you can give will be appreciated.

I'd rather see you with 12 schemas than with 12 databases. Unless you have lots of CPUs to spare ... and lots of cash to pay for those extra CPU licenses.
Then again, I'd take it one step further and ask to investigate the base design. There should be little reason to change the schema based on time. Indeed, from what little I know of your app, I'd have to ask whether adding a 'date' column and appropriate views or properly coded SQL statements might simplify things. Interesting. If we were to have one big Customer table with views for each month, how would we handle the case where the May people have to see 50 character address and July have to see a 100 character address field. I guess we could have MAY_ADDRESS VARCHAR2(50) and JULY_ADDRESS VARCHAR2(100) and take care to make sure that people connecting as May can only see the May columns, etc. This is simpler than multiple schemas?
I may have overly simplified things in my effort to get something down that would not require too much explanation. The big thing is that multiple people are doing development and they have to be independent of each other. If we were to drop a column for July, the May people will have trouble compiling if we don’t keep things separate. It is not a case of making the data available. The data in development is something we cook up to allow us to test. The other part is the code we compile now will be released to production one of these times. In production, there is only a need for one database.
We are moving from another database product where multiple databases are effectively different sets of files. We have lots of disk space so multiple databases were no problem. Oracle is such a powerful product; I can’t believe there is not some way to set up something similar.

How do I select from multiple schema's

How do I select from multiple schema's
Tried:
SELECT * FROM schema1.table1, schema2.table2

Errored......

Thanks
We finally got in touch with our DBA and he said the same thing.

How to run applications with options in IDEs like Netbeans

Hi, I'm new to the Netbeans IDE and I'm wondering how to run applications with options.
Normally I'd enter the following in the command line:

java -Djavax.net.ssl.trustStore=mytruststore -Djavax.net.ssl.trustStorePassword="..." TLSClient localhostProblem is, I've no idea how to do the same thing in IDE's like Netbeans and I can't any settings to add options like "-Djavax.net.ssl.keyStore=mykeystore" before running the application. Any help will be appreciated.

Webdynpro application with multiple DCs

Hi,
I have an application where it is splitted in to multiple DCs for the team development. Now at runtime there are navigation happenening across DCs, means on click of a button in view1 of DC1, it needs to call view2 of DC2. What is the best way to achive it? Is there a way to direcly call a DC component at runtime?
Any help?
regards,
Sujesh

Hi Sujesh,
First I want to point out, that DCs do not communicate with each other. DCs are designtime constructs which comprise development entities with runtime and/or designtime relevance. Inter-DC calls are Inter-DC-object calls.
Is your question related with the problem how to communicate between Web Dynpro components of separate DCs? To answer this question you must know how to develop Web Dynpro applications based on using separate DCs. This is done by defining DC-usage relations based on Public Part Definitons. When these DC-relations are correctly set up you can use Web Dynpro entities from other child DCs in a parent DC as if these entites would be contained in the parent DC. The runtime dependencies (sharing references etc.) are defined automatically.
Regarding your "Best Design" question I reply with a simple but quite effective principle: <b>"Favor DC-separation of Web Dynpro development entities!":</b>
- Separate Web Dynpro components in separate DCs
- Separate Web Dynpro Models in separate DCs
- Separate Local Dictionaries in separate DCs
- Separate Web Dynpro Component Interface Definitions in separate DCs
- Seaprate reusable Web Dynpro components in seaprate DCs.
Best regards, Bertram
P.S.: Look at my corresponding tutorial dealing with multi-component application design: https://www.sdn.sap.com/irj/sdn/downloaditem?rid=/library/uuid/bd0e0401-0801-0010-aaab-d0e1742da383

Deploying a large Oracle BPM Application with multiple UI projects

Hi everyone
I'm working on a large application with Oracle BPM 11.1.1.5.0.
I'm using JDeveoper 11.1.1.5.0 to build the application.
The application has lots of user tasks with lots of UI projects (one for each user task).
My problem is, each time I make a small change in the project, I have to deploy the whole thing, which includes one main project and five or six UI projects (for now) for the user tasks.
As the application gets bigger I'm sure this will definitely become an issue.
So my question is if I'm doing this the right way? or should there be a more efficient way?
Thanks in advance
Edited by: luke on Apr 17, 2012 12:16 AM

Hi Luke
1. Generally, there is NO need to have One UI Project for one individual Task. Say you have like 10 Tasks (.task files) like Initiator, Approver, Reviewer, LegalApprover etc etc. You can have just One UI TaskForms Project and have taskDetails.jspx generated for each one of these Tasks. This is the preferred way.
2. Any Workflow Application should have just 2 deployers. Means one deploy is for actual Workflow stuff that will have the main BPEL or BPM Process, human Tasks etc etc. Basically all that goes into workflow project. And another deployer is the REST of the things means the TaskForms UI Project and any other supporting projects like EJB projects, utils projects, any WebServices projects (if you have WebServices). All these will be deployed as one SINGLE EAR.
Lets take an Example from JDeveloper IDE point of view.
1. Application Name: SalesOrderApp
2. Workflow Project Name: SalesProcess (This is a a jdeveloper project of type BPM Project or SOA Project and has all human tasks, bpels, bpm process, business rules etc etc).
3. UI Project: SalesTaskForms (This is a auto generated form for the very first Task that you choose. Then for rest of the Tasks use this same Project, to generate jspx for all other .TASK files. REFER online docs on how to do this. I will see if I can compile this list of urls for you).
3. Supporting EJB Projects: MyEJBProject1 (Some EJB Project that connects to some backend database specific to your project)
4. Supporting another EJB Service Project: MyExtServiceProject1 (Like another EJB Project, that pulls data from some external source)
5. Some WebService Project: SalesCreditCardValidationWebService (Some WebService Project to be deployed as .WAR file that does some service).
Try to apply SOA Concepts for each Service that your application needs. Instead of putting all the EJBs and everying in one single giant project, try to split them logically/business need wise and geenrate separate projects so that they can service as it is to other projects and other apps.
Anyhow, coming back, in above Example, you should have jsut 2 Deployement: 1 is Workflow SCA JAR File and other is full EAR file.
a) For the Workflow Project, right click and generate a Deployment profile to deploy just this workflow and NOT any other UI Projects.
b) For each individual project genereate a deployment profile like MyEJBProj1, MyEJBProj2, MyWebService1 etc etc.
c) For TaskForms project also, generate a deployment profile like SalesTaskForms. This will be a WAR file.
d) At Application Level, create a new Deployment profile of type EAR and now assemble all the projects under this EAR except for the Workflow project.
First you deploy Workflow SCA JAR file. You need to redeploy this again only when you make changes to workflow, humantasks etc etc.
Deploy full blown EAR file that has all the stuff (EJB JARs, TaskForm WARs, WebService WARs etc).
Anytime you change taskforms, or any java or ejb code, ReDeploy EAR file.
You should have one JAR and one EAR to deploy at the end of the day. Infact this is how it should go into UAT and Production. They should not have multiple JARs, multiple WARs to deploy. The reason we have separate Workflow SCA Jar file is, bcos workflow will not change frequenly. And also older versions of SOA/BPM (before 11.5 FP) have a huge disadvantage. Everytime we deploy workflow project, it will make all existing process STALE unless you deploy with a diff version. This is not an issue any more for 11.5 + FP (Feature Pack applied). Hence be careful when you redeploy workflow project.
Thanks

How to share account with multiple devices?

3 kids with 3 devices - an iPod Touch and two iPads Mini - family shares one account with Apple/iTunes and one library on our family PC. They use FACETIME and MESSAGES with their friends, and they all see each others messages and conversations. How do I fix this? Is there a setting or a way to create sub-accounts off the family account so they can still share the main library for music and video OR do I have to create separate Apple/iTunes accounts for each kid? Is there a setting on their devices that can help? Any help is greatly appreciated. I'm not even sure the right question to ask...

Hi, how to develop application , matching of userid and password to backend

hi masters ,
              , user have to give userid and password of back end sap system to see particular report. i mean there is a first view ( this first view muust not be first screen of portal ) with userid and password fields . after gave his id and password he can go to second view to see the particualr details .please suggest me about how to do custom bapi code and , in also webdynpro java how to develop .
           i know about sso. in this concept i have to use through webdynpro java only. no need of sso concept here .
          after giving the userid and password , those details must be match with backend sap database.if no one of userid and passwrod field is matching it has to show some error message. and in password field must be in encrypted letters .

hi surya,
Use JCO api to create connection to the backend.
[JCO tutorial|http://www.apentia-forum.de/viewtopic.php?t=1962&sid=9ac1506bdb153c14edaf891300bfde25]
On the webdynpro screen you can ask users to enter login id and password. Use this information to create connection to backend using JCO.
Hope this helps!
