UnitOfWorkChangeSet and deleted objects

I would like use the UnitOfWorkChangeSet for auditing changes made to the objects. It seams that the UnitOfWorkChangeSet contains new objects and updated objects, but I cannot find deleted objects. The function UnitOfWorkChangeSet.getDeletedObjects always returns an empty set.
1) How to get deleted objects?
2) Where can I find the best information about usage of the change sets?
3) Can I process the change set after calling the method commit or is it better do it in any SessionEvent method (if so - which method should I use?)?
Thank you in advance for any help
Jan Kostrhun

Hello Jan,
For effeciency reasons the deleted objects are only placed in the UnitOfWorkChangeSet in the case of Cache Coordination (Cache Synchronization). If your application is not configured to use Cache Coordination the deleted objects can be found in unitOfWork.getObjectsDeletedDuringCommit(). Please note that this is an internal method in TopLink that may change in future released.
Accessing the UnitOfWorkChangeSet after you have called commit is fine.

Cfldap and deleted objects container in Active Directory

Hello,
I am trying to use a CFLDAP query to bind and search in the
Deleted Objects container of Active Directory. This would allow me
to get the sAMAccountname values of the users who have been deleted
within the last default 60 days (searching tombstone objects in
Deleted Objects).
I have tried various methods including <cfldap
start="CN=Deleted Objects, DC=<domain>, DC=<com>> (I
am omitting the rest of the CFLDAP attributes in the example
above). I'm not sure if CFLDAP can even query the deleted objects
container. Has anyone had any experience with this?
Thanks,
Ben

Hi Michael,
Thanks for your help! I have however already explored those
solutions offered by Microsoft. Sadly, they only work in separate
programs (i.e. ldap.exe which comes with Windows Server tools).
After lots of research I have found a Java method that can bind
with the container and return the results. CFLDAP, I'm afraid is
just not capable of doing this - or at least I have had no luck
with it (I was connecting as domain admin btw).
The challenge now is to get the Java class to communicate
with the rest of my cf code.
Thanks again,
Ben

How to identify and delete objects after failure of registering XML schema

Hi,
I have tried to register a XML schema with many global elements but failed.
I have checked the view DBA_XML_SCHEMA and found that there is an entry for this failed XML schema and the disk spaces would not be freed after the failure of registration as well.
I have tried DBMS_XMLSCHEMA.deleteSchema() with DELETE_CASCADE_FORCE but failed with ORA-31000: Resource is not XDB document.
How can I identify and delete the objects for this failed XML schema and free up the disk space ?
I would not prefer to use 'DROP USER ... CASCADE' since there are other objects owned by this user.
Thanks in advance.

you can get them from user_objects.
but you have to identify them manuallly if your schema has other objects other then created by the xml schema creation process.
Note these objects will be cases senistitive. so you should enclose them with double quotes during deletion.

Process Chain - mark and delete objects

Hello Experts,
i have the Process Chain with many e.g. DTPs. I would like to modify its, it means delete some DTPs.
I would like to mark several DTPs and delete them by using one "click". ( delete them ALL at once).
not to mark one and delete, mark second and delete ...and so on
Is it possible ?
Thanks for help in advance
Martin

Hello,
As per my knowledge , there is no such option. But you can go to particular DTP's Context menu and select the option remove from process.By this it will be removed from the process chain.
Hope i understand your requirement.

Archive and delete sap event management objects

Team, I need to configure the archiving objects and residence time to Archive and delete EM objects. there are three steps of configuration, and I have never done this before.
Can any one of you help me in setting up this config and the programs that need to run to archive and delete these objects.
I would really appreciate you help and quick response on this.
Define Archiving-Object-Specific Customizing
Define Residence Times for Archiving or Deleting
Define Settings for Deleting Document Flow
Thank you!!!

Hello Steffen,
I was told that it would be possible to display archived and deleted event handlers using BAPI /SAPTRX/BAPI_EH_GET_DATA_GEN. I tested it, but could not verify this statement. SAP Help reads:
"The archiving object /SAPTRX/A0 only supports a technical view in the Archive Explorer of the Archive Information System. This view is similar to the display in transaction SE16."
It would be great if you could help clarify this. Thank you!
Best regards,

Bitlocker to Go and deleted computer object

When encrypting a USB drive using Bitlocker to Go and storing the recovery information in AD, where does it get stored? Is it in the computer object like regular Bitlocker? If so, if the computer is retired or the AD computer account is deleted,
do you lose the recovery information for that drive?

Hi,
Backed up BitLocker recovery information is stored in a child object of the computer object. That is, the computer object is the container for a BitLocker recovery object. If you delete a computer object from AD, you will also delete the BitLocker recovery
information, which is a child object.
But you can use AD restore mode to retrieve the deleted object.

Deleted objects and nstombstone objectclass

Hi,
When i delete objects in DS5.0 with ldapdelete, DS5.0 create an objectclass nstombstone for all the deleted objects.
I can see them with ldapsearch ... (objectclass=nstombstone). Then, the size of the file id2entry.db3 increase.
I use a multi master replication between two servers and the id2entry's file sizes increases on the two server.
Why does DS5.0 create this objects and how can i delete them ?
Thank you for you help,
Guillaume

Directory Server 5.0 provides support for MultiMaster Replication. As changes can be done on 2 masters as the same time, the server may have to resolve some conflicts and therefore must maintain an historic of all changes that occured. The way to keep track of deleted entries is by marking them with a special objectclass and making sure they are not returned in regular searches (actually the only way to retrieve them is by specifying a filter objectclass=nsTombstone).
The server does some cleanup on a regular basis and has a thread that removes very old deleted entries. By default, these entries are removed after a week. You can reduce this age by changing the nsds5ReplicaPurgeDelay attribute value but note that this will also reduce the accepted delay of broken replication (and the age of a restored backup).
The result of setting a too small value would be that in case of problem, all the consumers will need to be re-initialized.

Ludovic.

Difference in the count of deleted objects in recyclebin and user objects

Hi
I m using Oracle 10G in windoes 2003 server. We queried on the recycle bin and the user objects for the deleted objects and found that the count is different. Here are the queries which i used to check.
1. select object_name from user_objects where object_name like 'BIN$%';
2. select * from recyclebin;
When i ran 1. in our user mshist and msmodel, the counts were 343 rows in mshist and 514 rows in msmodel.
when i ran 2. in our user mshist and msmodel, the counts were 353 rows in mshist and 530 rows in msmodel.
Kindly advise me why exactly is thr the difference as they both are checking the deleted objects in a schema.
Thanks
Ram

How to delete objects created in IR and ID

Hello ,
What is the right way to delete the SWCV from IR and Configuration scenario from ID .
I am using PI 7.11 version. Also, want to know that ,if i want to take backup , then how to do that.
Thanks in advance.
Ravi

Hello,
What is the right way to delete the SWCV from IR and Configuration scenario from ID .
You start from the top to the bottom, by this I mean you delete objects in this order
ESR:
Operation Mappings -> Message Mappings -> Imported Archives -> Service Interfaces -> Message Types -> Data Types -> Context Objects -> External Definitions
ID:
Receiver Agreement -> Sender Agreement -> Interface Determination -> Receiver Determination -> Communication Channels -> Business Component/Business System -> Party
I am using PI 7.11 version. Also, want to know that ,if i want to take backup , then how to do that.
Transport your SLD, All ESR objects under that SCV, All ID objects under that SCV as a file and then save in your local directory. That way, even if you deleted the objects you can still reimport them when the need comes.
Hope this helps,
Mark

Dreamweaver deletes objects (and is super laggy)

It took my 2 months to get rid of the slow laggy typing issue and now Dreamever decides to delete objects from my page. Every time I make a link, edit a photos properties, change a table, anything, as soon as it applies the change it deletes the object from the page. Luckuly I can "Command Z" it back but it is the most annoying thing in the world right now.
Also it goes through periods of being super slow to even select and highligh text or tables.
Please get a stable release out and forget all the fancy new stuff without making sure the basic functions work!

My problem:
1)
I am not able to write to the file. I want to know, where i am going wrong.
It is giving error message like
"Canot resolve Symbol: temp,"
But, FileWriter Constructor should accept a File type parameter.
here temp is a file parameter.
If i am not using file=new file();
i can't delete the file after the use. i.e if i use
PrintWriter p = new PrintWriter(new BufferedWriter(new FileWriter("cute.txt",true)));
how can i delete cute.txt after the use?
2)
I am not able to write to the text file. file is created but, a blank file.
"Hello" is not written into the text file.
can anyone help me in this regard
Thanks in advance
Ashvini

Thank you Ram,
But, i want to create a text file in Append mode.
for that i used
FileWriter fos = new FileWriter(temp,true); But, it is not accepting FileWriter constructor in
this format. if i use
FileWriter fos = new
FileWriter("c:/ash/cute.txt",true); it works fine. !!!!!Here's the javadoc
public FileWriter(File file,
boolean append)
throws IOExceptionConstructs a FileWriter object given a File object. If the second argument is true, then bytes will be written to the end of the file rather than the beginning.
Parameters:
file - a File object to write to
append - if true, then bytes will be written to the end of the file rather than the beginning
Throws:
IOException - if the file exists but is a directory rather than a regular file, does not exist but cannot be created, or cannot be opened for any other reason
Since:
1.4
Are you using jdk.13 or lower ?
>
ONe more doubt, Does flush method deletes a file?
if not, then i need to use
File temp=new File("c:/ash/cute.txt");
FileWriter fos = new FileWriter(temp,true); //which
is again a problem
if(temp.delete())
out.println("File is deleted");
}I don't know whether i am taking it wrong ! or
anything wrong with my coding ! but, after creating
and writing data into a text file. I must delete it
as it contains confidential informations.
Regards,
Thanks.'flush' writes to a file immediately. Else you should explicitly call 'flush' to write contents from buffer to underlying source.
javadoc again
PrintWriter
public PrintWriter(Writer out,
boolean autoFlush)Create a new PrintWriter.
Parameters:
out - A character-output stream
autoFlush - A boolean; if true, the println, printf, or format methods will flush the output buffer

How to search and delete an email from the mailbox

hi,
have a hybrid scenario, exchange 2013 and office 365
what command should I use to search and delete an email from the organization mailbox i.e. I do not want that email to be in any users inbox.
I have tried this command but it does not work, it says search-mailbox is not recognized as the name of the command let.
Get-Mailbox -ResultSize unlimited | Search-Mailbox -SearchQuery 'Subject:"Download this file"' -DeleteContent
kindly assist.
Kind Regards, Khuzema R.

Hi Khuzema
This can be accomplished by search-mailbox command
First you need to create a new role group
To Create – New-RoleGroup “Mailbox Import-Export Management” -Roles “Mailbox Import Export”
Then add the user to the group
To Add user – Add-RoleGroupMember “Mailbox Import-Export Management” -Member Administrator
Search the mailbox
get-mailbox -ResultSize unlimited -IgnoreDefaultScope | search-mailbox -SearchQuery ‘Subject:”virus infected”’ -LogOnly -TargetMailbox administrator -TargetFolder filter -LogLevel Full
Now we need to run the below command to search the infected emails and delete all of them in the whole organization
get-mailbox -ResultSize unlimited -IgnoreDefaultScope | search-mailbox -SearchQuery ‘Subject:”virus infected”’ -TargetMailbox administrator -TargetFolder filter -deletecontent -LogLevel Full
Also you can do a message tracking with the subject and delete them
Get-ExchangeServer | where {$_.isHubTransportServer -eq $true -or $_.isMailboxServer -eq $true} | Get-MessageTrackingLog -Messagesubject “Virus Infected” | Select-Object Timestamp,ServerHostname,ClientHostname,Source,EventId,Recipients
| Sort-Object -Property Timestamp
I have written a blog with regards to the same. You can always refer this which might mostly help you in your scenario

Is there a way to create a transport to mass-delete objects from another system?

I am facing a unique issue where I have to generate a transport that will successfully import into an external SAP system and delete over 1,000 objects (reports, data elements, UI elements, transactions, function groups, the whole lot...). All of these objects can be easily looked up because they are in the same namespace.
Essentially, I need to remove all objects with a given namespace via transport.
Is there any way to do this other than manually deleting all of the objects in the source system and adding them tediously to a single workbench request? This would take hours if not days to do manually, especially due to dependency issues.
Thanks for any and all constructive feedback!

Hi,
I did a quick test: created a new package (development class) with one table, one function group using the table in global data definitions containing one function module referring to the table in interface, and one program that's calling the function module and using table in data definitions. Released the transport to Q.
Then, in the second our dev system, I created the same package and TADIRs for the three objects manually (SM30); released transport to Q of that system. Then I manually created transport containing all the three objects, the export log looked like this:
TADIRs in second dev system were gone after export.
Then I added transport to the first development system and imported
- the objects were gone (including their TADIRs) leaving the empty package.
In retrospect, I should have deleted the empty package in second system so it's cleaned up by the same transport.
If you do have access to "clean" system, doing via ABAP the steps I did manually should not be too much of a challenge.
I may have simply gotten lucky and if this works with all objects, for all kinds of dependencies, remains to be seen... though I was until now under impression that import itself doesn't check any dependencies at all... What kind of messages were you getting?
cheers
Janis
