DBMS_XMLSave AND trigger

Why isn't possible to use DBMS_XMLSave into an INSTEAD OF TRIGGER context !
XSU want to set a savepoint and this is not allowed into a trigger.....

How about a trigger with autonomous Transaction ? as you said there would be performance issue with this approach . but for the sake of invoking a trigger through shell script , i think this may work . I could invoke a procedure using DBMS_SCHEDULER through a Trigger. have to try a shell script.Perhaps you're not understanding the transactional issue here.
In the simplest example...
You insert a record
Your trigger fires
The trigger calls the shell script (autonomous transaction or not)
The shell script does it stuff
For some reason, the transaction is rolled back rather than committed
Now the record isn't inserted, but the script has been run anyway.
Firing non-transactional processes from within a trigger is Wrong! It's bad design, it's flawed, it just shouldn't be done, this is NOT what triggers are for. There's also the risk of a trigger firing more than once per insert under certain circumstances.
There is nothing wrong with having a scheduled task running periodically (and that can be very frequently) to pick up flagged records and do what is needed. That ensures transactional integrity because it will only pick up things that are committed. It also prevents performance issues. The end result is more robust and can meet the requirements to have a process fire for any newly inserted records. It has the added benefit that if the external process (a script in your case) needs to be turned off, that can be done without effecting the rest of the application, as it is running independently.

Creation of sequence and trigger for each table!!!!!!!1

Hi
I am new to trigger and Sequence field. In one of my database we have many tables with fields for specifing ID numbers. Iam planning to insert the ID field with help of a Sequence and trigger...that trigger fires by adding the sequence value from the dual table. Now the point is here we r having around *60* table with ID field. And i am planning use the above process for each table by creating sequences and trigger for each table.
Will this affects the performance of database.
Is there any other option other than the above process, I mean other than creating sequences and trigger for each table.
PLzz help to resolve this issuee......

Tiger, I didn't mind about your comment, but the point is try to use
select NVL(max(a) + 1,1) into i from p1_temp;This line in your trigger code and see what is happening. The problem is with your trigger. You are using group by function and you will not get no_data_found !
For more help, this is some modification of your code.

Check for duplicate invoices and trigger a workflow

Hello All,
I have a requirement to check for duplicate invoices in AP(Accounts payable) and trigger a workflow when duplicate invoices are found. I a not sure how to do any of the above. Please let me know if you have any information on:
1) Checking for duplicate invoices in AP
2) Trigger a workflow
Are there any standard workflows that checks duplicate invoices?
Thanks.
--Mithun

Hi MD,
I doubt if system gives an error on FI side when a duplicate invoice is posted.
I feel you would require a BAdi for it, where you can call your WF using FM SAP_WAPI_START_WORKFLOW.
Hope it helps.
Aditya
P.S also ask your Func Consultants, if there are any settings in the Customization, where you could capture Inv Dt, Inv Amt, Vendor, Company code.

How to assign output type and trigger printing in ABAP

hi all,
i have create invoice by using BAPI_BILLINGDOC_CREATEMULTIPLE and create header/item text with CREATE_TEXT.
please advise how to assign the output type and trigger immediate printing after this.
thanks.

Hi Reetha ,
This is a functional setting , and should be done by some functional guy. The setting can be done by NACE.
Just follow the path : NACE - > Select V3 for Billing - > Press Output type Button Just above - > Assign Output Type and
then Assign Output program and form in PROCESSING ROUTINE comes into left. Set this output type for immediate print.
Whenever You create a billing document by BAPI with this document type , the print out will be fired immediately.
Hope it will solve your problem.
Thanks.

OIM: Create new link and trigger a process.

Hi,
I am customizing the OIM admin and user console. My aim is to add a new menu item and trigger a new process (say a provisioning process of a resource).
I have the menu link. I can point it to any servlet I want.
I have a resource object.
I have the form made using form designer in designer console.
I have a provisioning process attached to my resource object.
Now, how should I connect all these things together as to make an end to end flow.
Like how should I link such that a user can try to provision (self provision) my resource to himself by clicking on that link.
Thank you.

My second problem:
I want a way to say invoke a servlet (that I can do, but dont know which servlet to invoke.) so that my form (from the form designer) pops up, and I can fill data in it to create its instance. And this would trigger an approval process and provisioning process.
At last a page is returned stating that provisioning was successful or unsuccessful.
Thank you.

Suppress auto sequence and trigger DDL for surrogate keys?

Is there a way to suppress trigger and sequence creation for surrogate keys when export to DDL file?
I know most of the time the automatic sequence and trigger creation is welcome and very handy.
However I'm migrating from an old Designer model and there only the needed sequences are created.
They have a different name and trigger logic is custom (and generated outside designer).
There is a lot of package code depending on this. So I prefer to create and use different sequences.
Is there a way to achieve this? Any tips are welcome.Create

Hi,
Note that generating the DDL for Oracle 12c means that it will attempt to use your Oracle 12c Physical model. So if you normally use Oracle 10g or 11g, you will find that any details from your Oracle 10g or 11g Physical Model will not be included. So this approach may have other implications for you.
If you are not using Oracle 12c, there are some relevant properties on the Auto Increment tab of the Relational Model properties dialog for the Column which may help:
Sequence Name - allows you to specify the name of the Sequence (which can be the name of a Sequence defined in the relevant Physical Model).
Trigger Name - allows you to specify the name of a Trigger (which can be the name of a Trigger that is defined for the Table in the Physical Model).
Generate Trigger - unsetting this will stop the Trigger being generated.

If his user id exits in table A
Then allow him to update the TABLE A

He will do all this process using forms
But i need to have trigger or procedure in database level for table
2) I have another table like 10 tables

3) I need to have a common Procedure and call that procedure in all tables in UPDATE TRIGGER

Sequencing and Trigger on Oracle 9i lite database

We created a schema (TESTSCHEMA) on Oracle 8.1.7 Enterprise edition and have a created a trigger which will use the sequence object to generate primary key for the table (TEST_TABLE)
Sequence creation:
CREATE SEQUENCE TESTSCHEMA.TEST_TABLE_SEQUENCE START WITH 6000 INCREMENT BY 1 MINVALUE 6000 MAXVALUE 6999 NOCACHE NOCYCLE NOORDER ;
Trigger creation:
CREATE OR REPLACE TRIGGER TEST_TABLE INSERT BEFORE INSERT ON TEST_TABLE FOR EACH ROW
DECLARE
pkValue NUMBER;
BEGIN
pkValue := 0;
Select TEST_TABLE_SEQUENCE.NextVal into pkValue from dual;
:NEW.TEST_KEY := pkValue;
END TEST_TABLE_INSERT;
We have created a snapshot of the schema on mobile server, synchronized the data with the client (Win32 for testing purpose).
The trigger works fine on the server, but when I run the same query on the lite database with msql it gives me an error:
[POL-3221] null key in primary index
I was wondering if Sequence generation and Triggers are supported on Oracle 9i lite database ? Or am I missing out something ??
Any information/ help is appreaciated
Thanks

You can't use SAVEPOINT / ROLLBACK TO SAVEPOINT statements in the database trigger:
ORA-04092: cannot SET SAVEPOINT in a trigger
ORA-04092: cannot ROLLBACK in a trigger
I am not sure what you need exactly, but you can try this:

How can I execute a button-process and trigger a branch??

I create a button (ADD),
a process (seq:30 condition:ADD button)
and a branch (seq:50 condition:ADD button point: on commit:after process).
I wanna execute this process by click button, then trigger this branch to other page.
but now, only process had executed, not to to other page.
Please help me If you know it. Thanks a lot!!

Hi
If you amend the button to redirect then surely it won't fire the the process?
Check to ensure that there is no Unconditional Branch before your Conditional Branch. If there are, this will be firing before your branch.

HTML DB 1.6 (Apex) htmldb_util.set_session_state and Trigger

Hi everybody,
I have two “1.6 HTML-DB applications”: “Number 1” and “Number 2” which I use the same « before insert » trigger.
But, in application “Number 2”, I want to skip some instructions, I want to put a condition.
Firs of all, I would add an element “abc” in the page 1 of application “Number 1” to affect it the “Yes” value and in the page 1 of application “Number 2” to affect it the “No” value.
First of all, I taught to add a condition in the trigger.
begin
If abc = ‘yes’ then
def……..
Xyz……
End if;
Azb…..
Yjn……
End;
But, someone told me to use “htmldb_util.set_session_state”, but I’m not sure to fully understand the reason to use that. Can someone could help me ?
Thanks. Bye.

Firstly, I would never put ApEx page item references directly in a trigger. Surely, you can refer to the underlying column value that's supposed to be coming in rather than a page item. This might mean that you create a separate procedure to do your insert operation but it keeps things a bit cleaner and, to my way of thinking, more manageable.
Second, just null out the value of the page item (with a computation or a process) when you click the create button - after the value has been used and properly inserted into the table.

ORA-00022 with Database Link and Trigger

Hello altogether,
I got a very strange behaviour with my oracle 10.2.
I have two nets N1 and N2, where N1 can access the servers in N2, but not the other way round. In both nets I have an Oracle database running (D1 and D2).
In N1 I calculate some data, which must be replicated to the database in N2. I do this by using triggers on my tables in database D1 copying the inserted or changed data to D2 by using a shared public database link.
This works fine most of the time. But sometimes I get the following error:
ERROR [STDERR] Caused by: java.sql.SQLException: ORA-02068: following severe error from D2
ORA-00022: invalid session ID; access denied
ORA-06512: at "CUSTOMER", line 13
ORA-04088: error during execution of trigger 'CUSTOMER'
When I use the database links manually, they work.
Any idea?
Thank you!!
Daniel

The ORA-02068 message might be important
02068, 00000, "following severe error from %s%s"
// *Cause: A severe error (disconnect, fatal Oracle error) received from
// the indicated database link. See following error text.
// *Action: Contact the remote system administrator.Have you searched Oracle support for any bugs associated with the ORA-02068?
Was the remote session killed, the remote database changed to restricted session, or bounced?
I take it the distributed session is created using a dedicated session and not shared server?

How to adding new operation and trigger PR

Hi guru,
I am seeking an opinion and recommendation:
We have a process flow where we need to create a purchase order when we reach a specific operation in the routing. This purchase order is send to a external vendor that gets information to arrive to the factory and finsh an operation.
The routing consist of 4 operations:
010 assembly,
020 - testing,
030 - machine polish(triggers the PO to the vendor when operation 20 is confirmed),
040 - packing and the milestone.
Normally the routing only consist of 3 steps - assembly, packing and testing. but for these special machines we add the extra operation to have the machine cleaned. We need to have a solution for how the new operation can be added to the routing and in the same time trigger a Purchase requistion.
Thanks.
tuff

Hey Gorla,
Thanks for you feedback.
two questions:
1 - currently the routing of this material consists of only three operations (i.e. 0010 - Assembly, 0020 - Testing in Production, 0030 - Packing). So if I want to adding in this subcon operation (ie. machine polish) to the between 0020 and 0030, I will have to adding it manually. Will this cause problem? sorry I am not a PP person.
2 - may i know the "external processing control key" you mention is the technical field PLPOD-STEUS appear in the "Display Routing: Operation Overview" screen in CA03?
Thanks

ILA, How to qualify and trigger on a subset of signals?

Hello Vivado ILA users,
I am trying to verify a signal processing block that is too large to verify in simulation. Instead, I am using Vivado ILA to capture the data and writing out the data using the "write_hw_ila_data" command. Then I have a special script that converts the binary strings into a matlab readable format. It was a lot of effort to get all that working but now I am hitting a situation where the ILA no long meets timing. I could turn down the clock but I think the problem is how I am using the ILA.
The data in my block flows in a streaming fashion with a datavalid signal indicating when data is available. I only want to capture valid data so I have turned on the storage qualifier mode of the ILA. It seems that trigger/qualifier logic is being generated for all the data signals that I am capturing, not just the very few signals I use for trigger and qualification. I think this super wide trigger/qualifier logic is what causes ILA to miss timing.
Is there a way in Vivado ILA to select a different set of signals for triggering and qualification?
I remember this was part of the standard flow in old ISE Chipscope but I do not see how to do it in Vivado. I looked through UG908 and PG172. I should mention that my clock frequency is only 200MHz, very moderate for 7-Series parts.
I attach my add_ila.tcl script and then the long path of the timing report below.

Update: I recompiled my design with storage qualification turned off and the ILA still misses timing by half a nanosecond.
Then I compiled the design without any ILA installed and met timing by 2ns.
I remember using large ISE Chipscope cores at 300MHz in Virtex-5. Is there some funny business here? Do I need to constrain the ILA by some means other than the clock period constraint I put on my design?
