Protect DesignTime Object In GP
Hai All ,
I Developing objects in Gp at Designtime . By creating the Folder under that callable Objects , Actions,Blocks,Process.
I want Protect my Objects.
No other user will not able to modify.
How to Do this !
if any one know tell me..
Hi there,
Maybe you should take a look at which portal roles to assign to the user that is procssing a task, or executing a process. For example, some roles permit users to only view a DO without editing it, other roles permit users to see only runtime tab, etc.
Take a look at this doc for NW 7.0:
http://help.sap.com/saphelp_nw70ehp1/helpdata/en/ff/1b3a4209a6ae04e10000000a1550b0/content.htm

Protect object from accidental deletion
When I first tested this, I noticed that protect object from accidental deletion adds and explicit deny for everyone to delete and delete subtree for that object only. However, after testing a bit further, I noticed that if you create a protected OU inside
another protected OU, the parent OU will also gain the ACE deny Delete All Child Objects for the everyone group.
Now, why on earth would that be a good thing?? I know most of you will answer "because of accidental deletion" but if that's the case then the child OU should also have the same rights (and all the problems that are inherited with the having of
these rights).
A move of an object is a create on the target OU and a delete on the parent OU. This basically means that if you have:
An OU named "Groups" that is protected from deletion, with a child OU called "Specific Groups" also protected from deletion, with a Group called "My Test Group" under "Groups" OU and another group called "My Specific
Test Group" under "Specific Groups" OU then "My Test Group" cannot be moved, deleted, etc whilst "My Specific Test Group" can, despite the fact that both OUs are protected from deletion. Even if you then delegate rights to
Create, Move and Delete groups because the deny takes precedence the delegation would be useless...
Unless you are an organization where you never have an OU inside an OU containing other objects, how would you possibly benefit from this, and is there a way (without doing it manually) protect ONLY OU's from deletion without protecting child objects?
JohhHi Marcin,
It does facilitate OU protection, but by default in 2008 R2 when you create an OU it is set to be protected. Ensuring people untick the box and then manually protect that OU (by assigning rights directly to it rather than ticking the box) every time an OU
is created for something as futile as preventing an OU from being deleted is almost a complete waste of time and the effort vs utility almost dictates that we'd be better off not having the prevent accidental deletions there at all. After all, we've survived
Windows 2000 and 2003 without this functionality...
As for the scenario, I'll give you a very simple example:
You have Workstations under Workstations>Department Name>Desktops. You obviously have several GPOs linked at either one of those 3 places. All of a sudden, as part of testing a new deployment, you are required to add another GPO to the existing ones.
As part of the testing phase, you create a Dev OU under Desktops and link the new GPO to the new Dev OU. At the same time that you do this, do you really go and create a new OU under Desktops to hold all the already existing objects under desktops and therefore
prevent having any leaf-level objects and an child OU under the same parent OU? You could claim that a better way of doing it would be to create a Test OU at the top level of Workstations, but then you'd have to work out the effective permissions and GPOs
at the other OU level and replicate it on the newly created one... -
Smartview Problem with Protected Sheets
Hello,
We use Hyperion Smart View in our company and discovered a problem while using protected excel sheets while the addin is active. Excel asks for the password but doesnt accept it even if it is the right password. If we disable the addin the problem disappears. Has somebody else such a problem ?
Has somebody a solution or a workaround ?
Thanks for the helpThis issue was logged under Bug 6591401 - When Smart View is active and the worksheet is protected, the following error message is encountered ''Drawing Objects in one or more sheet(s) in the workbook are protected. Please unprotect them and try to save again.'' However, Bug 6591401 has been closed as not a defect.
The following is an explanation of how Smart View handles protected cells and a workaround for this issue:
Smart View needs some place to store it's own metadata within the Excel spreadsheet and it has been using a certain non-obtrusive object for the same. In versions 9.2 and prior, Smart View attempted to unprotect the Excel worksheets to be able to write it's metadata. That led to unexpected behavior when there were passwords used with the protection. This was fixed in 9.3.1.1.2 to make Smart View elegantly honor the spreadsheet protection and not touch objects which are specified as out of bounds by the user. However, when a spreadsheet is protected, this object can become inaccessible to Smart View, after which even a simple save operation cannot go through. In that sense, the current behavior is indeed the correct behavior, where the user placed restriction is honored correctly. The next question will be how can customers then work with protected sheets.
While protecting a worksheet, the following dialog appears which is where the user will have to establish what kind of operations will be allowed on this worksheet. By default the top two options are the only ones that come pre-selected. Just allowing these two options is not sufficient for Smart View to be able to work with the worksheet.
What also needs to be enabled is the option for "Edit Objects" which appears towards the end of the list. It is this option that helps Smart View to be able to persist it's own metadata within the worksheet in a non-obtrusive fashion. The guidance to all Smart View users should be to start enabling this option too, if they choose to apply worksheet protection.

Grant privilage to access diff database objects
How can we grant access to user1 from db1 to access user2 schema objects in db2 database ? Well, the user1 needs to perfrom insert, update and delete on db2's user2 schema.
hare krishna
AlokYou may create a new schema on DB1 and create all synonyms with appropriate privileges for all the tables which need access.
Create a database link from DB2 to access this new schema.
This way you will be protecting other objects from getting modified from DB2. -
I have an Object that I pull from a Hashtable. I don't know what type of Object it is, nor do I care. But I need to make a copy of it and .clone() is protected on Object.
eg.
Object obj1 = hashtable.get(key);
Object obj2 = obj1.clone(); // WILL NOT COMPILE (even in a try block)
Any ideas?If these objects were created by your code, then they each need to implement Cloneable and also implement a public clone() method. If you call the clone() method of Object via super.clone(), then it is a shallow copy and you'll need to copy any embedded objects yourself.
Assuming that all the classes in your Hashtable implement a public clone() method, then you'll need to either cast the reference to the appropriate class , or else use reflection to invoke the clone method.
e.gimport java.lang.reflect.*;
Object obj = yourHashtable.get("key");
try {
Method meth = obj.getClass().getMethod("clone", null);
try {
Object x = meth.invoke(obj, null);
...do something with cloned object x...
} catch (Exception ex) {
System.out.println("cannot call clone method: " + ex);
} catch (NoSuchMethodException nsmex) {
System.out.println("No public clone method exists: " + nsmex);

I would like to create a listener for java.util.LinkedList, so that when ever something is added or removed an event is fired.
Does any one have a good way about tackling this problem???If you don't care about using Swing classes then you can use EventListenerList wich is the most generic class extended by all the swing listeners. In fact if you are not using Swing then the best way is to copy this class to your application so you don't depend on Swing just to use a list of listeners (this class does not depend on any other swing class so you will not have any problem doing this).
The following is the source code of this class
package yourPackage;
import java.io.*;
import java.util.*;
import java.lang.reflect.Array;
* A class that holds a list of EventListeners. A single instance
* can be used to hold all listeners (of all types) for the instance
* using the list. It is the responsiblity of the class using the
* EventListenerList to provide type-safe API (preferably conforming
* to the JavaBeans spec) and methods which dispatch event notification
* methods to appropriate Event Listeners on the list.
* The main benefits that this class provides are that it is relatively
* cheap in the case of no listeners, and it provides serialization for
* event-listener lists in a single place, as well as a degree of MT safety
* (when used correctly).
* Usage example:
* Say one is defining a class that sends out FooEvents, and one wants
* to allow users of the class to register FooListeners and receive
* notification when FooEvents occur. The following should be added
* to the class definition:
* <pre>
* EventListenerList listenerList = new EventListenerList();
* FooEvent fooEvent = null;
* public void addFooListener(FooListener l) {
* listenerList.add(FooListener.class, l);
* public void removeFooListener(FooListener l) {
* listenerList.remove(FooListener.class, l);
* // Notify all listeners that have registered interest for
* // notification on this event type. The event instance
* // is lazily created using the parameters passed into
* // the fire method.
* protected void fireFooXXX() {
* // Guaranteed to return a non-null array
* Object[] listeners = listenerList.getListenerList();
* // Process the listeners last to first, notifying
* // those that are interested in this event
* for (int i = listeners.length-2; i>=0; i-=2) {
* if (listeners==FooListener.class) {
* // Lazily create the event:
* if (fooEvent == null)
* fooEvent = new FooEvent(this);
* ((FooListener)listeners[i+1]).fooXXX(fooEvent);
* </pre>
* foo should be changed to the appropriate name, and fireFooXxx to the
* appropriate method name. One fire method should exist for each
* notification method in the FooListener interface.
* <p>
* <strong>Warning:</strong>
* Serialized objects of this class will not be compatible with
* future Swing releases. The current serialization support is appropriate
* for short term storage or RMI between applications running the same
* version of Swing. A future release of Swing will provide support for
* long term persistence.

Any way to protect changes to our code?
Hi All.
There are 2 implementors for the SAP Implementation that we are currently involved in.
For ease of use of client, both are supposed to follow the same naming convention.
Now, is there any way we can protect our objects from being changed by other party? For eg, I could think of an authorization group which gives access to only those SAP ID's we want. We can attach such an auth group to programs.
But is there any way to protect all possible changes - programs, dict objects etc?
Hope my query is clear.
Any clues?
Thanks in adv.Hi
If your developers use own users (and nobody else can use those users), you can insert the flag to protect the editor.
This flag (is in the attributes of the report) can be removed only by the user setted it.

Exchange 2003 running on Windows server 2003. ~50 Users all in same OU on same domain with primary email address [email protected] objective is to create smtp contacts from each of the user objects imported back into the same domain in
a different OU with mail, targetAddress, proxyAddresses/SMTP on the contacts being [email protected] and the options 'automatically update email addresses based on recipient policy' disabled and hidden from GAL for all. At a later time will require
a method to bulk forward all of the user objects to their corresponding [email protected] contact object and a way to to bulk disable the forwarding at a later time.
ldifde created the contacts via export/import but Exchange seems to like rewriting the mail & proxyaddresses or replacing domain2.com with one of the internal recipient policy domains requiring manual change in AD.
ldifde -f export-01.ldf -s dc1.domain1.com -d "OU=Users,OU=people,DC=domain1,DC=com" -r "(&(objectCategory=person)(objectClass=user)(givenname=*))" -l "cn,givenName,objectclass,samAccountName,mail,physicalDeliveryOfficeName,displayName,name,description,sn,targetAddress"
ldifde -i -f import-test-01.ldf -s dc1.domain1.com
I'm then using ADModify.net to bulk modify hide from address lists attribute and correct the mail, targetaddress, proxyaddress attributes, possibly forwarding as well. The process is clunky compared to something like powershell on Exchange 2010.
Am I going about this the wrong way?users will remain on the domain. decommissioning or altering access to the old mailboxes until some point post-migration would be unwanted so there's a fallback method in case anything goes wrong. until testing reveals a better method, the strategy
for Exchange 2003 / Server 2003 environment will remain as is for now using ldifde export of select user object attributes followed by ldifde import of select attributes to contact objects, followed by admodify.net / admodcmd updating of the necessary mail/exchange
attributes via %’mailNickName’% similar to what's described below to forward internal mail to the external host.

Audio/Instrument objects "locked" in place??
Hello on this rainy Sunday, at least for me in Canada! Perfect day to stay in and work on music.
While building a new template for myself in Logic, all of a sudden I was unable to move my audio and instrument faders in the audio view of the enviroment. It was as if they were suddenly "locked" in place. Have I hit a key command that does this by accident?
Any ideas as to why this is happening, and how to reverse it?Turn off protect environment objects, it's in one of the environment local menus. When this is on, no environment objects can be moved or deleted.

Why are these protected- finalize() & clone()
Why are the methods finalize() and clone() declared as protected in Object class when any class that we write extends java.lang.Object? I mean what design considerations made them being declared as protected?
Object.clone() is protected so that it cannot be called unless the person writing the code intends it to be cloned.
In other words to make a class cloneable one must over-ride Object.clone() with a public method that does the cloning. In this way the method can only be called if an implementation of the mehtod has been coded.
Convinced this is poorly explained so reply if you don't get it!

Calling stored procedures from entity object and application module
Hello
I've put in place an EntiyImpl base class containg helper methods to call stored procedures.
I now need to call stored procedures from the application module.
Apart from creating an application module base class and duplicating the helper method code is there a way
to share the helper methods for calling stored procedures between the entity impl and application module impl ?
Regards
PaulDoes the helper code depend on features of a particular entity object instance, beyond its database transaction?
If so, I'm not sure I see how it could be used from an application module class.
If not, here's what you do:
Step 1:
Parametrize the database transaction--you might even want to. So instead of
protected myHelperMethod(Object someParam) {
DBTransaction trans = getDBTransaction();
change this to
protected myHelperMethod(DBTransaction trans, Object someParam) {
Step 2: make the method public and static--once you parameterize the DBTransaction, you should be able to do this.
public static myHelperMethod(DBTransaction trans, Object someParam) {
Step 3: Remove the method from your EntityImpl base class into a utility class:
public abstract class PlSqlUtils {
private PlSqlUtils() {}
public static myHelperMethod(DBTransaction trans, Object someParam) {
When you want to call the method from an application module, entity object, or even view object class, call
PlSqlUtils.myHelperMethod(getDBTransaction(), paramValue);
Unlike Transaction.executeCommand(), this lets you provide functionality like setting procedure parameter values, retrieving OUT parameter values, etc.
Hope this helps,

Is Object serialization secured?
Hi,
I wonder how secure is a serialized object being transported using TCP/IP Socket programming? Can someone sniff at my either server side or client side 's port to tap the object and then recover the information i send? Thank you very much.Serialized objects, by themselves, are NOT secure. You can protect the transport by using SSLSockets, or you can use SealedObject to protect the object over open transport.

How to allow users to run infopackage without giving access to Workbench
Hi,
I have certain infopackages which I want to give access to users to run. It mainly relates to loading of flat files which they want to be able to execute when they want and also loading the P&L data from R/3.
I am on 3.5..I don't want the users to have access to do anything else on the Admin workebench.
what is the best way? Is there a program or tcode which I can give access to the users where they specify the infopackage name and run it.
ThanksHi,
Create a role in transaction pfcg. Goto authorization tab-> change authorization data-> manual entry of authorization objects -> give the standard authorization object 's_rs_admwb'.
This autho-object is for protecting DWWB objects.
Inside this object , you will have option 'data warehouse workbench object' . Click change.. select 'infopackage'. In the activity you can give options display and execute. Save the authorization and generate profile. In the user tab, give the user ids of those who need to execute the infopackage. This should work exactly for your requirement..
Regards,
Krishna. -
Useful Code of the Day: Hideable Tree Nodes
Someone posted about how they could selectively hide tree nodes, and I already had this AbstractTreeModel class (which does some things DefaultTreeModel does and some it doesn't) and a concrete subclass for TreeNode objects, so I was thinking how one could do hideable nodes. So I came up with this solution.
There's 4 classes here:
- AbstractTreeModel is the base for the concrete TreeNodeTreeModel
- TreeNodeTreeModel extends AbstractTreeModel to support TreeNodes (DefautlMutableTreeNode, etc.)
- HideableMutableTreeNode which is a DefautlMutableTreeNode subclass which has a visible field (with is/set methods, of course).
- HideableTreeModel is the hideable model which is a subclass of TreeNodeTreeModel.
A HideableMutableTreeNode can be set invisible directly, but the tree still needs to be notified to update. So it's best to use the methods in HideableTreeModel which set a node's visibility which notify the tree of changes accordingly. Methods are also provided to check a full path's visibility or ensure a node including all parent nodes are visible.
A HideableTreeModel can take any TreeNode class, it doesn't have to be all HideableMutableTreeNodes, but only HideableMutableTreeNodes can be made invisible, of course. Any other TreeNode type would just be considered visible.
Hiding nodes works basically by making the tree think there's less nodes then there are. And to do this, the node counts and child index search just works by looping thru the parent's children. This has potential perfomance drawbacks of course, since one has to loop thru the node's children to get nodes every time. This could be alleviated by not supporting non-hideable nodes changing the internal maintenance of HideableMutableTreeNode contents. But I'll leave that to whoever really needs it. It shouldn't be a problem if there are are a relatively small set of child nodes in any given parent.
Also, note that the root node in the model cannot be made invisible, cuz it'd be redundant since JTree can be set to hide the root node.

I'm not trying to show anyone up here, but having just built a tree model for displaying an XML document in a tree, I thought this seemed like a neat exercise.
I implemented this very differently from the @OP. I only have one class, HiddenNodeTreeModel. All the hidden node data is stored in the model itself in my class. The advantage of what I've created is it will work with any TreeModel. The disadvantage is that I think it's not going to be very scalable - the additional computing to get the number of child nodes and to adjust indexes is heavy. So if you need a scalable solution definitely don't use this.
Anyway here you go
