Business Logic - Success of Tag and SQL Queries

Greetings All,
I have a Logic flow from an old NQL process.
The process Gets some SQL and Tag Data then checks to see if data was returned and notifies via email if data wasn't returned. So this would translate into the Tag and SQL Queries followed by a Logic Conditional block.
HERE's the questions:
In BLS, if the SQL and/or Tag Query fail, the entire process quits (at least when Executed locally) and never gets to the Logic Conditional block to verify the tagQuery.success or SQLQuery.success.
Is this what it does when run as a scheduled task also???
Is there any onError then do... type of parameter???
Any Suggestions would be appreciated...
Thanks
Dennis West

Dennis, it shouldn't "quit". The Success property should be set to false, and the error caught (typically). Sounds like a bug.

PLSQL Blocks and SQL Queries in APEX

Hello,
Is it possible at all to view undelrying Oracle PLSQL and SQL queries in a run time APEX 3.2 application?
More elaboratively, can a smart APEX Site user or visitor find a way to see underlying SQL queries and PLSQL code objects?
Thanks,
R

Hi,
If you just want to see what sql is executed by a session you can use sql trace. This can be switched on for a whole system but is usually more usable when switched on for individual users. The problem with a system like APEX is that database sessions are not directly associated with APEX users and APEX sessions can share database sessions.
I haven't tried it, but one method that may work is to put a schema logon trigger on the APEX_PUBLIC_USER which switches on tracing when ever this user logs on to the database. It may take a little detective work to understand the sequence of things but all the SQL executed by this user will be recorded and can be analyzed for performance etc. The command to enable SQL tracing could be embedded in the APEX app, but it may be a little random as to which db session has it enabled.
Perhaps a better tracing option could be seen as a feature request in a future version of APEX.

How exit for a script having set of pl/sql blocks and sql queries

HI,
I have set of blocks and sql queries in a script.
In some cases I want to stop the excution of next statements and blocks.
As in pl/sql block We can use return , in case of loop we can use exit, so what is to be use in case if sql script which contain set of blocks and sql queries.
Thanks and Regards in Advance,

Hi,
how to exit from the script if confirm_to_continue is set to 'N'.
i.e in this case I want the preceding statements not to be excuted.
Please suggest.
script:
declare /*BLOCK NO1*/
begin
IF &&confirm_to_continue = 'N'
THEN
---exit from from whole script
RETURN; -- this will only exit from this block
END IF;
end;
host IF EXIST &file_name (del &file_name) ELSE (echo missing)
declare /*BLOCK NO 2*/
begin
end;

JSP and SQL Queries

Hello,
If a JSP application needs Database connectivity to display some values, what is the best approch for the same.
1. Using SQL connections with resultset
2. Using Java Class and using the same in JSP.
3. any other??
what is the industry standard for the same.
Thnx,,
Girish

JSP's are used to display a view (such as a user interface or a report). Database connectivity is business logic and you don't do business logic in JSP's. I would create a servlet to handle business logic and then put the database logic in seperate classes that you can call from the servlet. Then use a JSP with JSTL to display the results of the database query. Putting the business logic in seperate classes makes it reusable.
Frameworks such as Struts, Spring, JSF, etc. work in similar ways, so I guess you can call it an "industry standard". In software development there is no such thing however, you develop to solve a problem, not to follow standards.
If you want to do it this way I suggest you lookup these two things:
1) how to make servlets and JSP's work together
2) the Model View Controller pattern

Business logic behind 2lis_12_vahdr ,itm and sch

Hello friends,
Could u help me in explaining the business logic behing the extractors 2lis_12_vahdr,VAitm,VASCH for deliveries?
Also why we use process keys and where do we use process key??
Thanks in advance
srini

Hi Srinivas!!!
The logic is like this.
When an order is made, it will have order number, line item number and schedule line item number. The order number is the header data and all information related to the header data is stored in 2LIS_11_VAHDR. Each order may have different line item, (different material may be ordered) that is stored in 2LIS_11_VAITM. Each Line item may be need to be delivered at different time because the users requested or may be there was no enough material in the store, this is stored in 2LIS_11_VASCL.
When delivery (2LIS_12_VDITM)gets created, it will abide by the schedule line agreement.
that is the logic.
thanks.

Authorisation Groups and SQL Queries

I want to give some employees access to certain SQL queries in SAP1.
I've created a Category Name and have ticked the Authorisation Group 1. Within this Category I've saved my queries that I want users to access.
I've then gone to Authorisations, General Authorisations, Selected the Employee, then Reports, Query Generator, and then allowed full authorisation to Saved Queries Group No. 1 and Read Only rights to Query Manager.
When user goes to Tools Queries, and selects Category name and any SQL query therein, cannot open.
I've tried allowing them full authorisation to Query Manager but this gives users access to ALL queries.
Any thoughts anyone?
D

Where is your Query Manager Authorisation ? I could only find Query Generator. If the same apply to you, then you don't need to assign any right to this category but only the selected group to full. Query Generator Authorisation will automatically become Various Authorisation.
Thanks,
Gordon

Indexes and SQL queries

I want to know if the index would be used with this query.
>
I have a table with 4 columns -- columns A,B,C, and D.
I have a unique index on columns A,B,and C.
If my SQL statement includes only columns A and B in the where clause, would this index be used?
The user arrived at from
The user appears to be using Microsoft Internet Explorer 4.0 (compatible; MSIE 4.01; Windows NT)null

Yes the index is used.
It's important that your clause contains column A (the firsto of the index)

SQL Queries in Code V/s Stored Procedures

Hi Friend,
Can any one of you guide me with following..
What is faster ? using SQL Queries in Java code or using Stored Procedures which are called from code?
I understnd Stroed Procedures are faster and definitely it provides more maintainability.
If any one can give me any links or resources which outlines pros and cons of using Stored Proc and SQL Queries embedded in Java than it would be a great help..
If there are any articles which proves either of the above is a preferred way, that would also help..
Appreciate the effort in advance !!
Thanks
Gurudatt

Well one benefit of Stored Procs is that you "compile" it on the database whereas you might build your query on the fly in java... test coverage is important in order not to have such things as a typo in a column name....
Still, if you change a table, you have to go through all the procedures in SQL and likely to do so in some of your business object... and trust me, that can be hell!
It all depends on the use of the app...
From my experience, Stored procedure are much faster than built-on-the-fly SQL (and quite faster than prepared statements depending on the JDBC driver, the re-use of connections etc...)....
IMHO, you'd probably be wise to start of with prepared statements, and when the schema seems stable enough (ie unlikely to change), look for the slower queries and convert them to stroed procedures.
If you don't have to support several databases and are tight on performance, you can even include some logic in your stored procedure (e.g. update several tables, based on various selects...etc...). The language is usually quite powerful, and that can save you the run-time of selecting, converting to object , process and update (i.e. several roud-trip between DB and app)...
Tshcuss!

ADF11g: business logic in ADF BC or PLSQL?

Hi All,
For a new development in ADF 11g , where we should put our business logic: In ADF BC or in PLSQL?
What if we write all the bussiness logic in plsql? Because if tomorrow ADF goes(which I know is not ging to happen soon), we can expose pl/sql as web services, and new UI technology can use it. And we will not struggle on migration, as we are struggling today from Forms to ADF.That's what my manager says......
Though I know that we can write our business logic in ADF BC, and that too can be exposed as web service.
But I still need more suggestion on this, which one is better to write bussiness logic.
Thanks
Vikram

We have a team with mixed skill sets, so consequently some of our business logic is in ADF/BC and some is in PL/SQL.
Having some in PL/SQL allows my project manager to divide and conquer the work to be done on an adf project easier than I can train the pl/sql guy to be an adf guy...supposedly.
Also our project manager is also a techy with a primarily pl/sql orientation.
I like Java better because it is new and fun for me, but that is not much of a reason.
I have been to many presentation's of Paul Dorsey's BRIM product. Paul is absolutely certain that you and your manager are doing good when you put business logic in the database. Paul goes even further. I respect him and his arguments are sound.
I still like Java better...mostly because I have done pl/sql for ages and am tired of it. :-)

Windows 2003 server and SQL 2008

Hi
Does SAP Business one support windows 2008 and sql 2008 platforms?
When i checked the partner portal it says that these platforms are not supported.Is there any update?
Regards
Louis

Hello Louis,
The only way to determine this is via the supported platforms page in the portal. This is the most up to date, and will include information for the future when this data is available. So for not I would only plan with what information is available.

Problem in Business Logic Callable Object execution

Hi All,
We are working on a workflow scenario where 2 approvals are present. Second approval is optional.
Second approval is required or not is decided by a business logic callable object.
This callable object is assigned (user role0 to initiator.
Issue is, when first approval is completed, flow goes to business logic callable object. A UWL entry comes in initiators inbox. And from there, flow doesn't move forward. It simply shows message 'The next activity is not yet available: try again later using the "Refresh" button".
I have tested this business logic callable object individually, and it works fine.
But in process, it doesn't move further.
What can be the solution to this?
Thanks,
Deepti

Hi,
I have the similar issue.
In my case it is taking too much time for completion.
It is a background step so it should execute automatically.
I have also checked Queue's for this.
But could not understand why it is taking soo much time?

Pratik

Future support for using PL/SQL core business logic with ADF BC

We want to migrate our large Forms client/server (6i) application to ADF, possibly using a migration tool like Ciphersoft Exodus.
One scenario could be to use ADF BC and ADF-Faces or a different JSF-Implementation for presentation and business layer but keep our heavy PL/SQL-businesslogic inside the Oracle database in packages, triggers, functions and procedures.
This scenario could be chosen due to the huge amount of interconnected logic inside the database (10 years of development; no technical components; any package may access any table and more of this kind of dependencies). The business logic nowadays held in Forms client will be moved mainly into the database as a prerequisite to this scenario.
Choosing this "keep-logic-in-DB"-scenario we need a good support by ADF BC to do so. We know and prototyped that it is possible to call some PL/SQL via JDBC from ADF BC and it is possible to use stored procedure calls for standard business entity data access (ins, del, upd, ..). But this does not solve our problems. We want to reuse core business logic coded in PL/SQL. This is much more than change the ADF standard behavior for an update with an own PL/SQL-call.
Now my question:
Will there be a kind of sophisticated support to use ADF BC in combination with database-kept logic?
If so, when will this happen and how will the common problems of transactional state inside the database and inside the ADF BC be solved? Any plans or ideas yet?
Many other clients do have similar applications built in Forms and PL/SQL and would be glad to hear about a path of direction.
I've read the technical article 'understanding the ADF BC state management feature' which you have contributed to. One current limitation is pointed out there: Using PL/SQL with ADF BC limits ADF AM pooling to 'restricted level' which reduces scalability.
Are you aware of additional main problems/tasks to solve when using PL/SQL heavily with ADF BC, which we have to think about?
Thank you for any response.
Ingmar

My main problem is two 'concurrent' areas holding state in an application system based on DB-stored PL/SQL-logic in combination with ADF BC.
For a new System everything can be made ok:
Sure, it is possible to build a new system with the business logic included in ADF BC only. All long-living state will be handled in the BC layer ( including support for UnitsOfWork longer than the webside short HTTP-requests and HTTP-sessions and longer than the database transactions.
For an old system these problems arise:
1. DB data changes not reflected in BC layer:
Our PL/SQL-logic changes data in tables without notifying the ADF BC layer (and its cache). To keep the data in ADF BC entity objects identical to the changed database content a synchronization is needed. BC does not know which part of the application data has been changed because it has not initiated the changes through its entity objects. Therefore a full refresh is needed. In a Forms4GL environment the behavior is similar: We do frequently requeries of all relevant (base)tables after calling database stored logic to be sure to get the changed data to display and to operate on it.
-> Reengineering of the PL/SQL-logic to make the ADF BC layer aware of the changes is a big effort (notifying BC about any change)
2. longer living database transactions
Our PL/SQL-logic in some areas makes use of lengthy database transactions. The technical DB-transaction is similar to the UnitOfWork. If we call this existing logic from ADF BC, database state is produced which will not be DB-committed in the same cycle.
This reduces scalability of ADF BC AM pooling.
Example:
a) Call a DB-stored logic to check if some business data is consistent and prepare some data for versioning. This starts a DB-transaction but does not commit it.
b) Control is handed back to the user interface. Successful result of step a) is displayed
c) User now executes the versioning operation
d) Call another DB-stored logic to execute the versioning. DB-transaction is still open
e) Business layer commits the transaction automatically after successful finishing step d). Otherwise everything from a) to e) is rolled back.
-> redesign of this behavior (= cutting the 1to1 relation between LogicalUnitOfWork and the technicalDatabaseTransaction is a big effort due to the big amount of code.

Business logic in PL/SQL?

Hello,
I am designing a 3-tier, web-based intranet application for my client. It's going to be a WebSphere portal app with Struts, running on Oracle 8.1.7.
One of the requirements is to implement the business logic in the back-end (PL/SQL), not in Java (although that is what I'm used to do). The reason probably has something to do with fear of performance issues ("the more code runs in Oracle, the faster") and resource planning ("more people here know Oracle better than Java").
This unusual (?) choice in my humble opinion leaves me with two major issues; how to cache database results and how to perform the O/R mapping.
I know how to use CallableStatements and JDBC, but I'd really like to avoid such a solution now we have EJB 2.1 and Hibernate and everything. And without caching as done by any sensible app server I fear performance issues.
Does anyone know a tool that can perhaps generate Java code and performs the O/R mapping? Or a tool that avoids me having to implement up to a hundred (!) CallableStatements and ResultSet-To-JavaBean mappings. I've seen Apache's commons-dbutils that seems to do this.
Does anyone have experience implementing business logic in PL/SQL and calling procedures from Java? Is performance really an issue here?
Thanks in advance for any input,
regards,
Bram Rooijmans

This unusual (?) choice in my humble opinion leaves me
with two major issues; In non-trivial applications excluding all business logic from the database is usually an architecture or design bug. Businesses do use the database directly due to legacy, tools, comfort level, etc. And in those cases the data still needs to be consistent. Not to mention that for some business logic the database can be orders of magnitude faster in running it versus external logic.
On the other hand I would consider it a bug as well if someone told me that all the business logic must be in the database and no where else. (At the very least I would suspect and question their definition of business logic in that case.)
I know how to use CallableStatements and JDBC, but I'd really like to avoid such a solution now...How are you going to implement any non-trivial business logic in oracle without using stored procs?
Does anyone have experience implementing business logic in PL/SQL and
calling procedures from Java? Not sure of the question. Certainly I have implemented business logic in PL/SQL. And many people have used stored procs via java.
Is performance really an issue here?No idea. That is a dependency of your system, not of java/databases in general.
I have seen java only solutions that even with scalling take hours to do operations that could be done in much less time using the database itself.
I have seen requirements which would have taken hours even in the database and changing the requirements meant it took less than 2 minutes. (It had nothing to do with java nor the database.)
I have seen code implementations which took significant database processing time where the entire solution could have been done without the database at all.
I have seen solutions where, due to business requirements, the same business logic was implemented in different languages and in slightly different ways in each. Implementing the logic in stored procs meant that all of the systems that used it now would be using the same rules. In that case it is possible that the solution was actually slower. But if it was it was not noticed and the consistency was much more important.

Bean containing both UI components and business logic

Hello ADF design experts, please guide me.   I came across a critical design aspects. I have main page having bunch of UI components,   Region 1, Region 2. I will have to bind the UI components of the page to a managed bean having session scope and the reason is, when control goes to region 1 or region 2, I will be doing lot of processing of business logic and then based on this, I will have to update the UI components of the page.   Same thing with region 2 also. And then, I should be able to access the information    across regions and also across other UI components etc.
I am seeing only session scoped bean will be able to help me here to get my tasks done across regions and across all other UI components of the page because I am not in a position to pass too many parameters across regions.     Now the problem is, I can not serialize this bean because as I mentioned lot of UI components are updated based on logic.
If I do not serialize the bean, I may have problem in future when application has to be deployed to cluster envt.
I do not know how should I go with my design now.   Please provide me brilliant ideas and very thankful to your guidance.
thanks

Hi ADF,
I dont want to disturb the discussion with you and Alej. I'm rising some question from your first post.
I have main page having bunch of UI components,
ok fine.
Region 1, Region 2. I will have to bind the UI components of the page to a managed bean having session scope
1.why need to do this binding for all ui components .?
2.this question lead ask another question are you using ADFBc.? if so binding layer will take care why you bind all those things.
3.why you need to put session scope.?
if you are using region. the region can only be bounded TF right, then communicate with help of pageflow. inside the bounded you may have jsff/jspx,
reason is, when control goes to region 1 or region 2, I will be doing lot of processing of business logic and then based on this, I will have to update the UI components of the page.   Same thing with region 2 also.
from the reason i have question? why you need to communicate between two region instead of using Taskflow communication.
And then, I should be able to access the information across regions and also across other UI components etc.
ok fine.
I am seeing only session scoped bean will be able to help me here to get my tasks done across regions and across all other UI components of the page because I am not in a position to pass too many parameters across regions.     Now the problem is, I can not serialize this bean because as I mentioned lot of UI components are updated based on logic.
from my point of view. your are using all powerful feature session bean, region communication to do your requirement.
mixing all those things so only you can't able to get consistent results.
I do not know how should I go with my design now.
could you please explain your usecase.
Please provide me brilliant ideas and very thankful to your guidance.
yeah sure. people will do.
thanks
