Delete attribute with objectclass=nstombstone

Hello,
I changed the replcation ID of one server in a three-way multimaster configuration, and found that the original value of the ruv is still exists in the search result of objectclass=nstombstone. That is there should be value of the replica ID of the three servers but now there are four value instead of three and I found the old value is not delete change the replica ID. Therefore I tried to delete this extra attribute, but it fails. Does it because of the objectclass=nstombstone? and could I delete such value?
Thanks in advanced.
Best regards,
PH

you can delete them but ONLY if you have replication disabled. i have a script that will clean up those things. at some point sun told me that all those unused ruvs could cause problems...i think they were taking a stab in the dark and cleaning them up never solved anything...only going to 5.2 with hotfix did. of course you could export, delete the ruv entries, and import...if u have a small db that might be the easiest thing.

Perl script to delete attributes with space value

Hi,
We are using Iplanet Ldap Directory server on hp-UX 11i.
I have a problem here with the attribute values.There is a space (a blank space) for few attributes across the directory server.
They seem to be normal when lokked through the ldap console. But when retrieving data through ldapsearch utility they appear as Junk character.
The only solution for this may be find and delete those attributes and add new one's.
eg: telephoneNumber :: RASWD== ( when the attribute has one space value,nothing else)
My issue is iam not able to trace the attributes through perl ldap scripts.
If anyone can help me out with a script it would be great.There are few thousand employees data appear corrupted.
Thanks in advance.

This is how SunOne avoids storing lots of extra spaces (and thus using disk/memory) It base 64 encodes the entries. I believe you can use the -B flag to ldapsearch to display the entry as it really appears not encoded.
If you really wanted to ideantify them I would write a perl script to locate attribute:: in a db2ldif of the install.
That would at least tell you which ones have the issue with spaces

AD user script to populate the IPPHONE attribute with the last 4 digits of the Telephonenumber attribute

Good Afternoon Scripting Guys. I have a script that I have been working with pretty much all day today and just cant quite get it to play nice. Our objective is to search AD for specific users (say filtering them out with a username that starts with a "T")
and User account is "Enabled" then grab the last four digits of their phone number (phone number is set up as follows: (800) 123 456 ) then populate the IPPHONE attribute with the last four digits of their phone number. I have read a ton of online
blogs with users successfully making this happen but it appears that they are all using Quest (as the commands are all Get-qaduser and Set-qaduser). I need something that runs strictly in native Active Directory Module PowerShell on a Windows Server 2008r2
Domain Controller. I am also trying to keep it as simple as possible by using a Get command, then piping a Set command. I have saved the script into a .ps1 file with the logic as follows:
$SelUsers = Get-ADUser -filter {(SamAccountName -like "t*")} -Properties ipphone,telephonenumber -searchbase "OU=Test Users,OU=Temporary Org,OU=Test_Domain Users,DC=mydomain,DC=com" | where {($_.enabled -eq $True)}
foreach ($user in $SelUsers)
{$user.ipphone = $user.telephonenumber(4,$User.telephonenumber.length-4)
set-aduser -instance $user}
What is happening is kind of funny, but aggravating at the same time. When we run the script, it completes with no errors. When I pull up the properties of a user in the OU, the IP Phone field is populated with the number 8. If the User
account did not have a telephone number, the IP Phone field is populated with a -4. So, apparently, the script is somehow subtracting the "-4" from the number of all of the Telephone Number field's characters. Basically 12-4 is 8.
If there is no telephone number, then 0-4 is -4. I have run the Get-ADUser portion of the script independently so I know its getting the correct users. I also know it is populating the IPPHONE attribute but not with the last 4 digits of the telephone
number. Can you guys help out and maybe get this to work correctly? Also, can you add logic to it to the script to delete any value in the IPPHONE field first, then replace it with the last 4 digits of the telephone.
Any help would be GREATLY appreciated!!!!! Thanks Guys...
Lee

First thing I would do is modify your filtering. This will remove the unneeded piping to the Where-Object cmdlet and also allow us to only return users who already have something in the telephoneNumber field. It is possible this could return all of your
users, but if you have service accounts, etc. that do not have a telephoneNumber then they will not be included in your results. It's just a little cleaner.
$SelUsers = Get-ADUser -filter {(SamAccountName -like 't*' -and Enabled -eq $True -and TelephoneNumber -like '*')}
I suspect you may have a made a mistake when you entered what your phone numbers looks like. I assume that you forgot a final digit. If this is correct, and you have a space in the phone number between the three digits and the final four then you can use
the split method to grab the last four digits.
Foreach ($User in $SelUsers) {
$Number = $User.telephoneNumber.split(' ')[-1]
Set-ADUser -Identity $User -Replace @{ipPhone=$Number}
There's no reason to delete what's in the field first because that's part of what the -Replace parameter will do anyway. This should help get you started!

Master data deletion - text with compounding

HI All,
I have " 0PYMT_METH" Info object which is having "0PYMT_METH_TEXT" Data source. " 0PYMT_METH" Info object is having text and 0country with compounding attribute.
- First , I did not load this master data , I loaded transactional data. so some values for key are loaded without text and country in master data.
- Later i came to know we need text for paymnt method, then i loaded again master data. but i am not able to delete previous entries which have blank text.
-i deleted data with SIDS and deleted all the transactional data , still i am getting that entries with blanks.Because of this in report output i am getting # value for the text.
How to solve this? Is it because of compounding attribute ? If so can u please suggest regarding this ASAP?
Thanks in advance,
Jo

Hi,
Please check the data load for the text as you must be loading
MAster Data CHAR , Country , LANGUAGE and TEXT as fields in your data source.
As the Text can be over written so if the porper key fields are matched the text should be modifyed everytime.
SO please check what combination you r loading .
ANyway if that is one time , and very less data you can manually maintain th text for master data .
In order to delete teh data you use SE14 use the text table there to delete the data. PS : This is not recommended solution .

Delete attributes and text of particular hierarchy

Hi All,
I'd like to know if it is possible to delete attributes and texts of a particular hierarchy in an infoobject (with hierarchy), e.g. product hierarchy?
I do not want to delete it manually?
Could this be done using process chain?
-WJ-

HI ,
GO to se80 -> select function Group -> give RSHI and press enter . In the section below it shows all the function MOdules belonging to this Function Group . In this there are function Modules related to Hierarchy Maintenance . SO i think this Function Modules will help u .
IF u find any function Module , then u can create a custom program and call the function MOdule in it . THen u can include the program in the Process Chain .
Assign points if it helps....

Object would have more then one attribute with the tag :VALUE

I'm creating a new component in Ultiboard - a 100 pin connector. This connector (Hirose) has 4 rows of 25 pins. Alternate rows are staggered. I'm trying to name each pin with it's appropiate name: A1, A2, A3 ....A50. Then B1, B2, B3 .....B50.
When I change the VALUE or NUMBER attribute, I get the DRC error message:
This action cannot be completed because the resulting Object would have more then one attribute with the tag :VALUE
Please remove one of the attributes and try again.
Okay, so I've tried deleting the tag and now I can't name the pin at all.
What am I missing?

You should be in the footprint editor to edit the pin name. Select tools>>Database>>Database Manager, highlight the component in your database and click on the Edit icon. In the footprint editor, double click on the pad and a SMT or THT pin Properties dialog appears, select the Attributes tab and highlight the Number row, press the change button and you should be able to change the pin name.

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. But we could extend this to the ALL_* views). I never met a system where different tables have the identical FK constraint names, however just make this fool proof.</li>

Deleting rows with missing values in field in start routine of update rule

Hello experts,
how can I delet rows with missing values in a specific field in the start routine of update rules?
I think ABAP code should look something like this:
delete ... from DATA_PACKAGE where Z_NO = ''.
thanks in advance for any suggestions!
hiza

Write:
delete data_package where field = value.
Hope it helps.

I deleted Scramble with friends on my iPad. It wasn't working properly. Then I couldn't find it to reload it. I found it with my iPhone 6 but it is not in the cloud to use on my iPad. What's up?

I Deleted Scramble with Friends Free from my iPad because it was not working. It closed every time I tried to play a game. Then I tried to reload it. It's not in the App Store. Then I found it on my iPhone 6 and loaded it. It still doesn't show up on my iPad. I have not upgraded to the ios8 operating system as I heard it would make my iPad not work properly. where is Scramble with friends and why cant I find it in the app store on my iPad?

That app is made for the iPhone - the app will work on the iPad but is not specifically designed to take advantage of the larger screen.
When searching for an app, look at the top of the screen for a button that says iPhone Apps. Tap on it to switch to apps meant for iPhone and Scramble with Friends should show up.

Change page attribute with JavaScript

Hi,
hope someone can help.
Is it possible to change a BSP page attribute with JavaScript??
I have a JavaScript array with some serialnumbers. After push a save button, i want to save the array data into a page attribute.
Some ideas?
Regards Anton

Hi,
The only way of passing vars from JS to page attributes is submitting them via (hidden) values in a form or via params in an URL.
Alternatively, you can try to let JS store things in a client cookie and let the BSP read that cookie.
I didn't try that out yet though.

How can I move or delete files with PL-SQL???

I have Oracle 9i and Sun Solaris 5.8
I have a table (TABLE_FILENAME) with the files name in one directory. (I read the files name in a directory and put it in a table). I charge some files with external tables and then I have to move some fields to another directory and delete others files.
How can I delete files with PL-SQL and How can I move files with PL-SQL?
I have the names of files and the actions (Delete o Move) in a table (TABLE_FILENAME) (The files in this table are dynamics).

If you're using 9i then you will find that the new functions UTL_FILE.FCOPY and UTL_FILE.FREMOVE will allow you to do what you want. Check out the documentation for more details.

one Windows Server 2012 R2 as file share server (SMB), stores all VM files. The share is managed by SCVMM . uses local SSD disk. two gigabit ethernet ports connected to a switch.
two hyper-v hosts running Windows Server 2012 R2, non-clustered, managed by SCVMM, each hosts has three gigabit Ethernet ports connected to the switch.
Everthing works including live migration. Here is the problem:
When I deleted a VM with checkpoint, it appeared that SCVMM/Hyper-V merges something, it took a lot of time on reading each AVHDX and write to VHDX, this results two problems:
1. It took a lot of time and bandwidth. I am about to delete the VM (and all its files). Why SCVMM/Hyper-V wants to merge all files? The deletion took 29 minutes for a 36GB VM. This VM is just plain standalone VM, no usage of template.
The expected result is to just delete all VM files and remove VM, don't do merge. (BTW: VMWare doesn't do merge, the deletion is done in a few seconds))
2. although all data file are on the file share, the hyper-v host still reads each file from file share, then write to another file on the same file share. It consumes significant network bandwidth. Can they offload the work to file server?
The expected result is that Hyper-V offload the transfer to file share server. It should not create huge amount of network io.
3. The merging operation is incredibility slow. around 24MByte/sec data being copied.
The hyper-v has 2xgigabit links, benchmark shows the file share access can easily go 200Mbytes/sec, and the file server side is SSD drive with 200+MByte/sec bandwidth. The expected result is if hyper-v ever merge, the speed is least 100MByte/s and hopefully
go up to 200MByte/sec. 21MB/s is just painfully slow.
Did I miss anything?

Thanks for the info. Even there may be use cases where merge is necessary, there are plenty of use cases where merging is overkill -- can Hyper-V have a CLI option that deletes VM without doing merging?
If such option won't be available soon, can SCVMM do this on deleting a VM:
1. revert to the latest checkpoint, delete the checkpoint
2. repeat the step 1 until all checkpoint removed.
3. delete the VM.
This workaround avoids the Hyper-V's merging. It is not as clean as VMWare's (they just delete the VM files, no extra merge), but at least it is much faster and less resource consumption than merging.
