Triggers in a package

I need to create a lot of audit triggers.
Is it possible to put them all inside a package or a procedure so that they are all together instead of seeing 200 triggers under triggers in TOAD.

No. Triggers are database objects, like tables or views, and no more capabale of being packaged.
If organisation bothers you, you could create an auditor account to manage you audit system and have it own the audit triggers, rather than the table owner. In general we just have to live with cluttered schemas for big apps.

Triggers inside a package

How do I use triggers within a package?

You don't. Triggers are pieces of code that we attach to database objects that contain events (tables, views) or events (logon, execute ddl). Of course, a trigger can execute stored procedures.
As I type this answer it occurs to me that you might be wanting to attach a trigger in order to do something every time a pacakage is excuted. If that is the case, then tell us what that something is and we may be able to ssuggest a workaround.

Query: Can we write Triggers in a Packages??

Hi Al

Triggers provide a way of executing PL/SQL code on the occurrence of specific database events. For example, you can maintain an audit log by setting triggers to fire when insert or update operations are carried out on a table. The insert and update triggers add an entry to an audit table whenever the table is altered.
The actions that Informix Dynamic Server triggers perform are constrained to multiple insert, update, delete, and execute procedure clauses; whereas, Oracle allows triggers to execute arbitrary PL/SQL code. Oracle triggers are similar to stored procedures in that they can contain declarative, execution, and exception handling code blocks.if you mean trigger call package, yes!

Creating triggers in a package

Does any body has an example on how to create triggers in package/package body.
Here is an example of one of many triggers that I need to create in a package.
CREATE OR REPLACE TRIGGER distributor_q_i

Hello
That idea is pretty much fine. If you're on 9i the values(rec1) will work, if you're on 8i you'll have to specify each column i.e.
SQL> CREATE OR REPLACE PACKAGE dt_test_package
2 AS
3 PROCEDURE proc1 (rec1 IN dt_test_tab2%ROWTYPE);
4 END;
5 /
Package created.
SQL> CREATE OR REPLACE PACKAGE BODY dt_test_package
2 AS
3 PROCEDURE proc1 (rec1 IN dt_test_tab2%ROWTYPE)
4 IS
5 BEGIN
6 INSERT INTO dt_test_tab2 VALUES(rec1.col1,rec1.col2);
7 END;
8 END;
9 /
Package body created.
SQL> CREATE OR REPLACE TRIGGER dt_test_trigger BEFORE INSERT ON dt_test_tab1 FOR EACH ROW

5 BEGIN

7 rec1.col2 := :NEW.col2;
8 dt_test_package.proc1(rec1);
9 END;
10 /
Trigger created.
SQL> insert into dt_test_tab1 values('col1','col2','col3');
1 row created.

Creating Info-Package Groups

Hi All,
We are running a Job through Process chain. But due to some bug it is taking 4 Hrs to complete. We tried executing the Info-Packages manually. It completed with in 30 Mins. So we are planning to create IP group to trigger that Job instead of through Process chain.
Can you please explain how to create the Info Package Group and how to include info packeges in to the IP Group.
After creating IP group we have to schedule a Job to trigger this IP group which inturn triggers the Info packages.
If possible please explain the steps for the above process.
Million of thanks in advance.
Regards,
Reddi.

Hi,
Procedure to create InfoPackage Group
Go to InfoSource tree in modeling of the Administrator Workbench and choose in the standard toolbar of the right area of the screen Show InfoPackage Group.
On the right-hand side of the screen, you will see the InfoPackage group tree.
Highlight a node of the InfoPackage group tree and create a new InfoPackage group using the context menu (right mouse click). This is always inserted underneath the highlighted node.
Select an InfoPackage (in the InfoSource tree in the middle area of the screen) that you want to transfer to the InfoPackage group and move it into the InfoPackage group you want by using drag & drop.
You can assign as many InfoPackages as you like to an InfoPackage group.
InfoPackages with the same selection conditions, same assignment for combination of InfoSource / DataSource / source system, same data type (transaction data or master data), and same data target cannot be assigned to the same InfoPackage group.
Alternatively to the above procedure, you can also create an InfoPackage group in the monitoring view of the Administrator Workbench. However, in this view it is not possible to insert InfoPackages into the InfoPackage Group.
You have created an InfoPackage group and have inserted InfoPackages into the InfoPackage group. You can now
Scheduling an InfoPackage Group
Choose Show InfoPackage Groups in the InfoSource tree of the Administrator Workbench Modeling, or choose the InfoPackages view in Monitoring of the AWB.
Select an InfoPackage group from the InfoPackage group tree and choose Schedule.
You arrive in the scheduler (InfoPackage group maintenance) with the InfoPackages and Scheduling tab pages.
Select the InfoPackages you want to load.
By default, all InfoPackages are selected.
On the tab page InfoPackages, number the InfoPackages that are assigned to the group according to the sequence in which the loading process is to be carried out.
For the InfoPackages, select whether you want the monitor to run a check during the data update to see if the first request from the list has been completely and correctly processed. Only then will the request for which this indicator has been set be processed.
Define a fixed delay of one minute for the individual InfoPackages. The delay represents the wait time until the next request is carried out.
Schedule the InfoPackage group in the background.

How can i access all the objects of one schema from another schema

Dear All,
How can i access all the objects(Tables,Views,Triggers,Procedures,Functions,Packages etc..) and do the modifications of one schema from another schema (Without using synonyms concept).
Thanks in advance,
Mahi

First of all, synonyms only help you easy reference the object. It doesn't have any implication of object privilege.
As long as you have proper privilege on target object. You can access it with or without synonyms.
Assuming you have proper privilege of objects, you can use following command to assume schema owner.
ALTER SESSION SET CURRENT_SCHEMA = Schema_owner

Reference to uninitialized composite

Lately we experience intermittent problems deleting data from tables with TAPI/TAPI triggers and CAPI packages (Headstart 6i). When deleting a relatively large number of rows, in this case 900, we get an ORA-06530 error which seems to be caused by the TAPI del procedure. Below is an example of the delete statement and subsequent error.
If we limit the number of rows to be deleted at once to e.g. 100 the problem disappears !
Has anyone experienced a similar problem and does somebody know what the cause and solution is ?
Thank you, Marcel.

CDM RuleFrame is optimized for very fast interactive processing. There are a number of known issues related to performance of the CAPI during batch operations. In the Headstart User Guide, in the Business Logic Layer section, we have documented a number of strategies to address this problem. It sounds like you are probably running into some kind of stack overflow. That would explain why both limiting the number of rows processed and disabling the rules in question both resolve the problem.

Solving "COMMIT business rules" on the database server

Headstart Oracle Designer related white paper
"CDM RuleFrame Overview: 6 Reasons to get Framed"
(at //otn.oracle.com/products/headstart/content.html) says:
"For a number of business rules it is not possible to implement these in the server
using traditional check constraints and database triggers. Below you can find two examples:
Example rule 1: An Order must have at least one Order Line ..."
But, one method exists that allows solving "COMMIT rules" completely on the database level.
That method consists of the possibility of delaying the checking of the declarative constraints (NOT NULL, Primary Key, Unique Key, Foreign Key, Check Constraints) until the commit
(that method was introduced first in the version 8.0.).
E.g. we add the field "num_emps" to the DEPT table, which always has the value of the number
of the belonging EMP rows and add DEFERRED CK which uses the values from that field:
ALTER TABLE dept ADD num_emps NUMBER DEFAULT 0 NOT NULL
UPDATE dept
SET num_emps = (SELECT COUNT (*) FROM emp WHERE emp.deptno = dept.deptno)
DELETE dept WHERE num_emps = 0
ALTER TABLE dept ADD CONSTRAINT dept_num_emps_ck CHECK (num_emps > 0) INITIALLY DEFERRED
Triggers that insure the solving of the server side "COMMIT rules" are fairly simple.
We need a packed variable that is set and reset in the EMP triggers and those value
is read in the bur_dept trigger (of course, we could have place the variable in the package
specification and change/read it directly, thus not needing the package body,
but this is a "cleaner" way to do it):
CREATE OR REPLACE PACKAGE pack IS
PROCEDURE set_flag;
PROCEDURE reset_flag;
FUNCTION dml_from_emp RETURN BOOLEAN;
END;
CREATE OR REPLACE PACKAGE BODY pack IS
m_dml_from_emp BOOLEAN := FALSE;
PROCEDURE set_flag IS
BEGIN
m_dml_from_emp := TRUE;
END;
PROCEDURE reset_flag IS
BEGIN
m_dml_from_emp := FALSE;
END;
FUNCTION dml_from_emp RETURN BOOLEAN IS
BEGIN
RETURN m_dml_from_emp;
END;
END;
CREATE OR REPLACE TRIGGER bir_dept
BEFORE INSERT ON dept
FOR EACH ROW
BEGIN
:NEW.num_emps := 0;
END;
CREATE OR REPLACE TRIGGER bur_dept
BEFORE UPDATE ON dept
FOR EACH ROW
BEGIN
IF :OLD.deptno <> :NEW.deptno THEN
RAISE_APPLICATION_ERROR (-20001, 'Can''t change deptno in DEPT!');
END IF;
-- only EMP trigger can change "num_emps" column
IF NOT pack.dml_from_emp THEN
:NEW.num_emps := :OLD.num_emps;
END IF;
END;
CREATE OR REPLACE TRIGGER air_emp
AFTER INSERT ON emp
FOR EACH ROW
BEGIN
pack.set_flag;
UPDATE dept
SET num_emps = num_emps + 1
WHERE deptno = :NEW.deptno;
pack.reset_flag;
END;
CREATE OR REPLACE TRIGGER aur_emp
AFTER UPDATE ON emp
FOR EACH ROW
BEGIN
IF NVL (:OLD.deptno, 0) <> NVL (:NEW.deptno, 0) THEN
pack.set_flag;
UPDATE dept
SET num_emps = num_emps - 1
WHERE deptno = :OLD.deptno;
UPDATE dept
SET num_emps = num_emps + 1
WHERE deptno = :NEW.deptno;
pack.reset_flag;
END IF;
END;
CREATE OR REPLACE TRIGGER adr_emp
AFTER DELETE ON emp
FOR EACH ROW
BEGIN
pack.set_flag;
UPDATE dept
SET num_emps = num_emps - 1
WHERE deptno = :OLD.deptno;
pack.reset_flag;
END;
If we insert a new DEPT without the belonging EMP, or delete all EMPs belonging to a certain DEPT, or move all EMPs of a certain DEPT, when the COMMIT is issued we get the following error:
ORA-02091: transaction rolled back
ORA-02290: check constraint (SCOTT.DEPT_NUM_EMPS_CK) violated
Disvantage is that one "auxiliary" column is (mostly) needed for each "COMMIT rule".
If we'd like to add another "COMMIT rule" to the DEPT table, like:
"SUM (sal) FROM emp WHERE deptno = p_deptno must be <= p_max_dept_sal"
we would have to add another column, like "dept_sal".
CDM RuleFrame advantage is that it does not force us to add "auxiliary" columns.
We must emphasize that in real life we would not write PL/SQL code directly in the database triggers, but in packages, nor would we directly use RAISE_APPLICATION_ERROR.
It is written this way in this sample only for the code clarity purpose.
Regards
Zlatko Sirotic

Zlatko,
You are right, your method is a way to implement "COMMIT rules" completely on the database level.
As you said yourself, disadvantage is that you need an extra column for each such rule,
while with CDM RuleFrame this is not necessary.
A few remarks:
- By adding an auxiliary column (like NUM_EMPS in the DEPT table) for each "COMMIT rule",
you effectively change the type of the rule from Dynamic (depending on the type of operation)
to a combination of Change Event (for updating NUM_EMPS) and Static (deferred check constraint on NUM_EMPS).
- Deferred database constraints have the following disadvantages:
When something goes wrong within the transaction, then the complete transaction is rolled back, not just the piece that went
wrong. Therefore, it becomes more important to use appropriate commit units.
There is no report of the exact row responsible for the violation nor are further violations either by other rows or of other
constraints reported.
If you use Oracle Forms as a front end application, the errors raised from deferred constraints are not handled very well.
- CDM discourages the use of check constraints. One of the reasons is, that when all tuple rules are placed in the CAPI,
any violations can be reported at the end of the transaction level together with all other rule violations.
A violated check constraint would abort the transaction right away, without the possibility of reporting back other rule violations.
So I think your tip is a good alternative if for some reason you cannot use CDM RuleFrame,
but you'd miss out on all the other advantages of RuleFrame that are mentioned in the paper!
kind regards, Sandra

System error in program RSMDATASTATE and form RSM_DATASTATE_CHECK-10-

Hi Experts,
We found an error ABAP/P Processor: Message_type_x and Error analysis shows "System error in program RSMDATASTATE and form RSM_DATASTATE_CHECK-10-"
I found a forum that close to my issue: ABAP Dump Error - System error in program RSMDATASTATE
Also, I checked the SAP Note : 858671 and 1094948.
As for my BW system, the system component information is SAP Netweaver BI 7.0 Release 700 Level 0019. Does it mean the both sapnotes alreay apply to my sap system?
Could anyone please advices me in this issue? I am so newbie in SAP BW. I'm so apology if they already have a forum or a note that related to my issue.
Thank you everyone for further assistances
With Best Regards,
Molly

Hi Molly ,
A per my experience and and observation. Message_type_x issue will occur in two scenarios.
1) When ever Sytesm copy happend.
2) Triggering of info package twice at a same time.
Case1:
When ever system copy happens, we will have init request still pointing to the Previous targer syatem's in Init.
Thsi can be resolved by reinitilization of source request.
Note: Make sure that Init reqiuest is same in both Source and Target systems.
Case 2:
Message_type_x May occur by triggering the info package at a same time twice(some time we also get xx request is inprocess alert).
With respect to the following blog:
Kindly check the request in RSMDATASTATE.
1) Request SID for which all requests are technically o.k.
2) Request SID for which all requests checked for quality.
3) Request SID, up to which aggregates are to be rolled up.
Best Regards,
Maruthi

Business logic in Database layer or in Middle layer.

I am converting my form 6i client server application to .net 3 tier web architecture application using oracle 10g database.
My application is a very data centric, millions of records calculations happen in many processes.
I have a problem while presenting my design approach to engineering board in my company.
Approach 1
Put business logic in backend database layer.
I proposed to put business logic in backend packages rather than putting it in middle .net layer and create web shell services in middle layer which would call these packages and show the data on screens.
Approach 2
Put business logic in middle tier .net layer.
My company engineering board are more keen for this approach because they think this is the latest approach and now days nobody put business logic in database and moreover we would be having clear separation between data and logic.
But my concern is we may have network latency issues in approach 2 because we need to move millions of records data back and forth between database and application server.
Could you please suggest, which approach is best and why?

My views:
1. If it is a data centric operation, like you have mentioned, it will be a bottleneck to transfer the required data to middle tier for processing
2. If you are going to support one and only one RDBMS as a backend ever, I don't see a reason to take an approach which is mostly taken in case one needs to support databases from different vendors as back end.
3. If you are convinced that yours is the only application that would ever connect to this database, then you can add the business logic in the middle tier; If not, let it be in the database in form of triggers/procedures/functions/packages etc.
4. Last but not the least, having business logic in the database would call for faster processing and that you can use all features of that particular RDBMS to full extent, in case needed.
I always support having the business logic in the database layer (not that I hate business logic in application/middle tier) but there can be exceptions.
Just my two cents :-)
