Cascading dependencies

i read some about the term 'cascading dependencies' which packages eliminates??? but what is that???
and speaking about packages, is it true that i cannot call a procedure in a remoter database using db links if that particular procedure references a packaged variable???
and what are global variables in a package??? where are they declared in spec or body???

Hi,
Cascading dependencies i will explain you latter. i have to check once.
Regarding your query:
is it true that i cannot call a procedure in a remoter database using db links if that particular procedure references a packaged variable???
It is written very clearly in restrictions on packages that :
You cannot reference remote packaged variables directly or indirectly. For example, you cannot call the following procedure remotely because it references a packaged variable in a parameter initialization clause:
CREATE PACKAGE random AS
seed NUMBER;
PROCEDURE initialize (starter IN NUMBER := seed, ...);
Also, inside a package, you cannot reference host variables.
Regarding your second question :
what are global variables in a package??? where are they declared in spec or body???
Global variables are always defined in specification of a package and advantage of using global variable is that use can use that variable in any where in your application by using package_name.variable_name. They are simply any variable defined in the specification of the package. But Some issues like persistent state has to be keep in mind.

Advantage of a package???

hi,
is is very well know that packages help in performace improvement, that is when a package member is referenced, all the package's contents are loaded into the memory, but how long are they stored??? is a LRU algorithm used or does it stay in the memory till that particular session is terminated??? its urgent kindly reply as soon as possible???

Hi,
According to oracle documentation :
When you call a packaged subprogram for the first time, the whole package is loaded into memory. So, later calls to related subprograms in the package require no disk I/O. Also, packages stop cascading dependencies and thereby avoid unnecessary recompiling. For example, if you change the implementation of a packaged function, Oracle need not recompile the calling subprograms because they do not depend on the package body.
Yes, its true that LRU is used for package swaping. But you can stop it also.
According to oracle documentation:
Another way to improve performance is to pin frequently used packages in the shared memory pool. When a package is pinned, it is not aged out by the least recently used (LRU) algorithm that Oracle normally uses. The package remains in memory no matter how full the pool gets or how frequently you access the package.
You can pin packages with the help of the supplied package DBMS_SHARED_POOL.
Hope this will clear your doubt.

[SOLVED] effective way to clean my system?

I would like to sort my packages by size in descending order, see what their names are and their descriptions, and then delete them if I don't want them anymore. Anyway to do this in an efficient way other than sifting through "pacman -Q", picking a package, doing "pacman -Qi package" and then deciding to remove with "pacman -Rsc package"?
Thanks!

nice, thanks shark and bohoomil, I was able to get almost a gig worth of cruft thrown out. Is there a script that allows me to specify number of dependencies? For example, when I do "pacman -Rs package" or "pacman -Rc package", I run into innocent-sounding packages that pull in hundreds of megabytes worth of packages (essential ones, at that). I am wondering if I can ask through a script something like "give me all packages that pull in at maximum X packages as recursive-/cascading dependencies, so I can identify packages that are less likely to be needed...
Thanks!

Perfomance points in packages

Hi all
sorry for asking an old question, just hoping to get some new answers, i recently went for an interview and i was asked "what are the advantage of packages?", i said
1.overloading,
2.encapsulation,
3.When you call a packaged subprogram for the first time, the whole package is loaded into memory. Therefore, subsequent calls to related subprograms in the package require no disk I/O
4.packages stop cascading dependencies and so avoid unnecessary recompiling
the interviewer said i'm missing one vital point in performace perspective and refused to tell that,
hi gurus can you kindly tell me what are the other points that can be added in the list of "advantages of packages in performance perspective"
Thank u

No. Procedures are basically used to create basic building blocks to extend the language - making it more flexible and powerful. And these are most definitely re-usable code.
Here is a basic example of how procedures are used in PL/SQL to extend the language by creating procedures to serve as "new language commands":
SQL>
SQL> -- a wrapper procedure that wraps raise_application_error
SQL> create or replace procedure RaiseError( errNo number, errMsg varchar2 ) is
2 begin
3 -- for debugging we can turn the following on: DBMS_OUTPUT.put_line( 'Error '||errNo||': '||errMsg );
4 -- we can also log the error to a log table via atonomous transaction, etc.
5 raise_application_error( -20000-errNo , errMsg );
6 end;
7 /
Procedure created.
SQL>
SQL> -- a utillity procedure to introduce a new command in PL/SQL
SQL> create or replace procedure Assert( condition boolean, errNo number, errMsg varchar2 ) is

5 end if;
6 end;

Cascading parent/child inserts while avoiding uniqueness constraints

Assume that I have two classes that I'd like to persist: MyObject and
InternalObject. MyObject has an InternalObject field. That is, MyObject is
the parent, InternalObject is the child in this one-to-one relationship.
Steps involved:
1) Enable ForeignKeyConstraints property in kodo.properties. That is add
the line,
kodo.jdbc.ForeignKeyConstraints=true
2) In package.jdo, add the following kodo extensions for MyObject's
InternalObject field mapping, i.e., io in my case.
<field name="io" default-fetch-group="false">
<extension vendor-name="kodo" key="jdbc-delete-action"
value="cascade"/>
<extension vendor-name="kodo" key="dependent" value="true"/>
</field>
The reasons that we have done these steps: we'd like kodo to properly
re-order the sql statements if necessary in order not to violate
parent/child dependencies during insertion, and also force cascading
deletes in case we delete the parent object.
Now comes the bulk of the algorithm.
String sKey // key of the object to insert
String sValue //value of the object to insert
MyObject o = new MyObject(sKey, sValue);
InternalObject io = new InternalObject(sKey,sValue); //using same values :)
o.setInternalObject(io); //parent-child relation
Object id = ((PersistenceCapable) o).jdoNewObjectIdInstance();
((PersistenceCapable)o).jdoCopyKeyFieldsToObjectId(id);
kpm.currentTransaction().begin();
try {
Object trio = kpm.getObjectById(id, true);
kpm.deletePersistent(trio);
kpm.flush(); //apply deletes on the datastore
} catch (ObjectNotFoundException oe) {
System.out.println("First time!");
kpm.makePersistent(o);
kpm.currentTransaction().commit();

If this is a question, the extension you have is only a directive to
mappingtool to create cascade foreign keys. However, at runtime Kodo
will rely upon the foreign key definitions in the schema. You should
verify that the foreign key exists as you like in the schema. If you
want to have child relationships to be deleted, you should use the
dependent and element-dependent extensions.

Cascading LOV in a Query panel (af:query)

Hi
I have a requirement to implement few Cascading LOV's in a Query panel. I have created the VO's for the LOV's with bind variable and view criteria and linked them. It works for the BC viewer. But to enable in the ADF UI, the partial trigger needs to be enabled on individual field. And the af:query encapsulates the fields and they are not exposed. Can someone help me with a solution or a pointer
Many thanks

Thanks for the pointer
Well I followed the the steps, and implemented the same for two LOV's. I'm getting "Server Exception during PPR, #1". Would be able to identify where I'm going wrong please.
FYI: I'm using a UI template that is stripped won from Oracles Dynamic tab template

Cascading List of Values & Query Panel

Hello all! ADF BC JDev 11
I should use Cascading List of Values in Search Query Panel. I build CLOV like in this sample http://www.oracle.com/technology/obe/obe11jdev/11/adfbc_new_features/adfbc.html .
But when i use it in Search Query Panel it does not work. :(((
I thik that i need to set partial triger on detail LOV field. How can i do that?
Help!
Edited by: Victor_V_S on 23.11.2009 7:45

Hello,
Thanks for a nice solution.
I have a similar situation.
I have a query panel with auto make name list of values returning make as name and make id into the hidden view attribute.
Based on this, i have another list of values namely auto model which is also a name field returning a name and id(hidden).
I tried choosing the auto model name field and editing dependencies as auto make id and later auto make name as well.
But i get this error in the Weblogic Log every time i selected the auto make LOV or auto model LOV and auto model does not filter based on auto name .
<SimpleSelectOneRenderer><_getSelectedIndex> Could not find selected item matching value "SomeNameViewCriteria" in QueryRenderer$2[UIXEditableFacesBeanImpl, id=null]
I have no clue how to handle this.
Any help is greatly appreciated.
Thanks.

Cascade delete of products in APO

Hi,
I´m wondering if there are predefined ways for deleting a product and all it´s dependencies totally in APO. (Cascading deletion). I.e. setting a flag in the product master and getting rid of all connected PPM:s, location/product split, quota arrangements etc etc... Anybody knows how to do this efficiently?
BR
Karl

Hi,
I wish SAP has provided something like this.
UNfortunately there is no one button where in you can delete all the dependencies
Let me list you the steps to my best knowledge
(1) Supply Chain Engineer -- TRansaction-- /n/sapapo/SCC07
You can delete most of what you have asked
Location, LOcation Product, Product, Resource, Trans Lane, PPM
(2) Remember before this step, you will have to delete all the orders in all versions for this particular product location.
Use report: /sapapo/rlcdelete to do this.
Sometimes not all the orders get deleted and when you try to delete the master data in SCEngineer, it will say that there are dependencies.
Then you would have to use the " WHERE USED LIST" for each master data and then it will display you the order numbers.
You would have to manually delete each order number using the RLCDELETE report.
Hope this helps.
Regards
Kumar

Hi,
I have de same problem.
I think that it could be a bug, cause if i check "show in list" option in the View criteria the messages are no prompted, and are prompted with that option unchecked.
Although there's no problem during execution.

What is the proper way to deal with cascading triggers in AcroForms?

(this has already been posted in the Scripting forum. Due to the lack of response, I am coming here to the Land of C/C++ Developers)
What is the proper way to deal with cascading triggers in AcroForms?
My question refers to the forms in which there is a binary question such as:
"Are you interested in travel?"
When the user clicks "Yes", there are further questions whose interactive fields are dot.hidden (or "!"), depending on the answer.
So far, I can handle the 1-level cases fine, but my doubt is how to implement nested dependencies. For the sake of simplicity, I would prefer to define the cause-effect relationship once ("Every time the 'Interested in Travel' box is checked, the field 'International or Domestic' should be visible") and send some sort of message/trigger downstream.
I would like the right things to happen (cascading triggers included) when the "Clear Form" menu command is selected.
Are those desirable features available in JavaScript (the particular JS used by the traditional AcroForms)?
Maybe I should look into C/C++ programming?
TIA,
-Ramon

I guess my problem is that I have some basic college experience in digital circuit design, and would like the forms to be programmed and behave in the same fashion as digital logic.
The "Clear Form" menu item, of course, would be equivalent to the reset button.
Perhaps it is possible to hook my code onto the "Clear Form" menu item?

Sql query to find dependencies for a table

Hi All,
I am having a table (REPT_ALL) with dependent objects on it ( child tables, indexes, constraints, views, synonyms, sequences , packages,procedures,functions,triggers).
I want the query to find out all the above dependencies for the above table(REP_ALL).
I m looking for the query to find dependencies inorder to find out the risks before dropping the above table(drop table REP_ALL cascade constraints)?
Thnx

To find foreign key constraints for a table you cannot use DBA_DEPENDENCIES but you have to use DBA_CONSTRAINTS.
Example Re: Find out foreign key column

Is there a way to remove packages that are installed as dependencies?

Hi,
I recently tried out GDM, and found that I don't like it. I now wish to remove it, along with all the dependencies that were installed along with it.
However, I cannot find a way to list the dependencies of GDM, so that I can remove those as well.
The pacman manual mentioned --cascade and --recursive , however cascade does not list anything else, and recursive includes WAY too many extra packages, many of which I actually need.
Is there a way to remove the packages that were installed along with GDM, but nothing more and nothing less?
Thanks,
James

I also remove packages with the -Rs switch. I occasionally check for orphans. In fact, I wrote an 'orphans' function in in my ~/.bashrc for this purpose.
orphans() {
if [[ ! -n $(pacman -Qdt) ]]; then
echo no orphans to remove
else
sudo pacman -Rs $(pacman -Qdtq)

Get('XML') doesn't work, but get() does in javascript - CASCADING LOVs

I'm trying to get cascading LOVs working in Apex 3.1.0 in Oracle 11g. When I call get.get('XML') it returns null in firefox and empty string in IE6. If I change it to call get.get() then it returns the XML as a string into Javascript.
The Application process is getting called in both scenarios as i've put PL/SQL logging to disk in order to prove it. The XML being returned is very basic so i'm sure it's not a problem with formatting. I'm not getting any exceptions thrown in javascript either.
Is it possible to use get.get() and then convert the text into an XML object which is returned as per get.get('XML') which at least will allow me to get something working ?
thanks

Hi,
I've been trying to replicate your problem here: [http://apex.oracle.com/pls/otn/f?p=37055:1]
My application process is:
BEGIN

<a href="javascript:getMyXML();">Click</a>Click on Click at the bottom of the page. The first DIV gets the get.get('XML') object and the second one the get.get() and a popup message tells you how many "select" items are in the XML version.
As far as I can see, this works fine.

How do I delete cascade with a PL/SQL procedure?

This script will create a PL/SQL procedure that deletes cascade. This is a post to contribute to the Oracle community. Take the code as is and test it before you use it in production. Make sure this is what you want.
Procedure Delete Cascade (prc_delete_cascade)
Description
=============
The principle is very simple. The procedure uses a table called TO_BE_DELETED to keep a list of records to be deleted. This
table keeps the table name and the rowid of those records that need to be deleted. The procedure also uses a function called
DELETE_BOTT_ROW which takes one record of the table and tries to delete it. If the deletion fails with a foreign key constraint
violation, the function parses the SQL error message (SQLERRM) to get the name of the constraint. With the name of the constraint,
the function finds the name of the child table, all the child records that have references to the parent table primary or unique key,
and the parent key primary or unique key column name. Once the child records of the failed delete are identified, the function takes their table name and rowids
and records them into the TO_BE_DELETED table by inserting records of their table name and their rowids. Al the records inserted also contain the level (which
is 1 for the original records, 2 for child records, 3 for granchild records, etc.) and the sequence number of the order in wich they
are recorded. This way, when the function picks up a record to be deleted, it takes the one with the highest level and the highest
inserted sequence, or the "bottom" record. Once all the child records of the failed delete are appended to the TO_BE_DELETED table, it calls itself
recursevely, and the function takes the record at the "bottom" of the table and tries to delete it. If it succeeds, it calls
itself recursevely to delete the next record. If it fails, it goes and finds the child records as described before and once they are
inserted into the TO_BE_DELETED table, it calls itself again recursevely to try to delete again the "bottom" record. All records
that are successfully deleted are flagged as deleted usig the flag_del column so they are not pickt up again. Once all the (parent,
child, grandchild, etc.) records are deleted, the procedure ends without commiting, giving the option to the user to commit or
rollback deletions. The table TO_BE_DELETED is, at the end of the procedure, a list of all the records that were deleted, including their table names
and the order in with they were deleted. The user then can review its content and decide to commit or rollback.
Restrictions
============
1. Single tables only. The procedure only takes one table name and a WHERE clause to identified the records to be deleted.
2. Single columns only. Ther procedure only works with single-column primary, unique and foreign key constraints.
3. Single schema only.
4. Unpredictable results with circular references.

Interesting.
I see a few areas where this could be useful. Elimiating specific test records from a Test DB for example.
Some comments:
<li>Since this is a recursive logic you must add a stop criteria. In this case I would add a max iteration variable. If that one is reached, raise an error message and let the procedure stop with that error.</li>
<li>The when others exception at the end should be removed completely</li>
<li>The when others exception in the middle should be replaced by a specific exception that handles the -2292 error</li>
<li>A list of tables where no record should be deleted could be usefull. If the logic would encounter such a table, it should also stop. This would be to prevent that data from some system critical tables could be deleted per accident.</li>
<li>The reference from the FK constraint to the PK constraint should include the table name and if possible the owner (as long as you use user_* views the owner is always the same.

Issue in EHP5 Talent Management (Team Goals) Cascade goals functionality

Hi Friends,
Issue in EHP5 Talent Management (Team Goals) Cascade goals functionality.
Under Team Object While try to cascade goals, it pop-Up Warning Msg u201CChoose Save to save the goal in the employee document. The goal can no longer be deleted, only set to obsoleteu201D.
If we click Ok to proceed further, I am getting error stating u201CYou have made no selection" and " No appraisal template defined ".
Same functionality is working fine in u201CPerformance Management (Predefined)u201D
With Regards
Seranjeeve Kumar

Please set the parameter PROCESS "PMP" in the iview configuration.
ie
ROLE_ID=PA&PROCESS=PMP in application parameters
content provided by SAP ->
specialist ->
Talent management Specialist ->
iViews ->
COmpany goals etc
and you can confirm using this
CL_HAP_CASCADE_GOALS > meth0d GET_VALID_APPRAISAL_TEMPLATES
The parameter mentioned in the note 1457057, the one that you enter in
transaction SE80 is the default value. However, if you call application
with parameter PROCESS=PMP then the PMP process for cascading goals will
be used.
check note 1523527
