Handling SQL exceptions

Hello

I have a problem to understand how to manage the SQL Exceptions when using JdbcService in LiveCycle ephemeral process.

Could you guide me to an article on handling sql exceptions?

I see, that many services a 'bolt' in its visual representation (for example the Document FileUtilsService/Write) and it is possible to define alternative workflows by dragging the new road of bolt.

What is the standard way to handle the sqlException exception then?

Thank you.

The latest version of LiveCycle contains a 'bolt' to catch exceptions.

If you use 8.2, you can try to take advantage of the Exception event.

Create a separate process and add an Exception start Point event. It must catch the exception.

PL/SQL exception handling and return values
Hi all

I use Oracle 10.2.0

I have a problem in the return values of the procedures if there is no exception.

For example:

procedure a.
(
P_in number,
p_out on varhar2
)
as
p_valid varchar2 (10);
number of p_no1;
Select 1 in double p_no1;
B (p_valid, p_no);
exception when others then
c (errmsg);
end;
put an end to;

procedure B
(
p_in number,
p_valid out varchar2
)
as
fake number;
Select 1 in double dummy;
dummy cases = 1
then
p_valid = "OK".
C (MSG);
end;
exception when others then
p_valid = "OK".
C (errmsg);
end;

end b;
In the example if theres no exceptions or dummy = 1 in procedure B, then I need to return the value as 'OK' in the setting out of the parent procedure "A".

I could not this value, returning null. How to get this...

Please advice...

TIA,

Ok

The code you have posted is not valid code if you have forgotten some important things. However, we will make it simple...

If you have a set OUT that will not be filled if an exception is thrown, unless it is set to NOCOPY.

Obviously, when the procedure B raised an exception it went directly to the procedure exceptions A manager that indicates that an exception has happened and the value returned in the OUT parameter was NULL.

Now, if procedure B just handles the exception rather than erect in...

Here, procedure B fills the output parameter and just returns execution to the block to execute procedure A, so A procedure isn't aware of no exception, but the output parameter does not contain the value B populated with.

But if you want the procedure B to throw the exception and pass out a value in the output parameter, you must set the out parameter as NOCOPY...

Now, as in the first example, procedure B defines the output parameter and throws the exception, causing execution to go directly to the procedure A exception handler, but this time, A procedure return parameter value out.

To understand the execution of blocks and managing exceptions take a look at this article...

Pure SQL Exception: Caused by java.lang.NullPointerException.

Could not invoke the 'Query_XX_Flag' against the 'db' operation due to: []
LIAISON. JCA-11633
Pure SQL exception.
Pure SQL select DECODE Execute (MSI. ATTRIBUTE5, 'Y', 'True', 'False') XX_flag of msi mtl_system_items_b where inventory_item_id =? and rownum = 1 failed.
Caused by java.lang.NullPointerException.
The pure SQL option is for only border use cases and provides simple but minimal functionality. Maybe try the "Run an operation on a table" option instead. This exception is considered non reproducible, probably due to an error of modeling.
Version: Oracle soa suite 12.1.3 - jdk1.7 - (local) Windows 7 operating system
I get the above exception in one of our Async BPEL of the process, and it happens like 1 in 5 cases.
As you can see, the reason for the error is not really clear and I see nothing diagnosis either connects.
And when I start this process from the console, it's getting completed successfully.
We are not exceeding the number of DB connections either.
Here's our design:
BPEL Poller-> (several calls) Async BPEL process-> database adaptor with above query
What could be wrong? What is the reason for this odd behavior?
Thank you
Prasanna

This error could not be reproduced on the test environment, where the SOA server with oracle DB of the backend rather than javaDB on integrated server is installed...

So if someone were unexpected exceptions on the local server and then try to test on the test/UAT/pre-production environments.

SQL exception while stretching, error object standard display - oracle.apps.per.selfservice.deployperson.PositionLovVO

Hello

SQL exception while stretching, error object standard display - oracle.apps.per.selfservice.deployperson.PositionLovVO

When I extend the standard above mentioned display object, with a substituted view object, the region of lov throws a sql error.
I just added an extra column in the viewobject.
I also tried to extend the view object without adding additional columns to the query of the view object, and it always up with the exception of sql.

I've provided steps to reporduce and test cases.

Thank you
Kind regards
