User X must not be deleted ? :-(

Hi Guys,
When I try to delete a user I receive the message: "User <login> must not be deleted"
Somebody knows why ? or .. should I block the user only ? or force a deletion ?
Thanks for your advice guys !
REgards,
Diego

Hi
Please read this ->
What happens if I delete the user who has created the shopping cart ?
<u>Answer -> If the user is deleted, and the shoping cart exists in the application, then the shooping cart cannot be displayed. If you want to view/ process those shopping carts, then you have to create a dummy user and retrieve the document. In CRMD_PARTNER table, the old user GUID should be replaced with the new user GUID.</u>

WLC 4400: User Account must not expire

Hi all.
Currently we have wireless guest user accounts added onto the wlc and they expire in 30days. No problem with this.
However, the wireless infrastructure is to be used by internal employees with local account db held on wlc. Can this be setup such that their account will never expire?
thanks a lot
Ajaz

Hi Ajaz,
Most possible my friend
Local Net Users
You can change a guest user account with a non-zero lifetime to another lifetime value at any
time while the account is active. However, to make a guest user account permanent using the
controller GUI, you must delete the account and create it again. If desired, you can use the config
netuser lifetime user_name 0 CLI command to make a guest user account permanent without
deleting and recreating it.
From the Lifetime drop-down boxes, choose the amount of time (in days, hours, minutes, and seconds)
that this guest user account is to remain active. A value of zero (0) for all four fields creates a permanent
account.

The list you saw that shows what drivers are available from Apple Software Update is based on what drivers are supplied by the vendor to Apple. So it would appear that HP has not provided Apple with a scanner driver for 10.9 (known as an ICA driver), or provided an update if one was available for a previous version of OS X, so that you can scan from Image Capture.
I checked the HP web site for your model and they don't show any scanner driver or scanning software. If there was a scanner driver, you would be able to use Vuescan.
As for the Scan button not working, the following is documented by HP
Scanning to the computer from the printer control panel is not available when you scan with Preview, Image Capture, or Printer browser methods. You must use HP Scan software to scan from the printer.
But there does not appear to be any version of HP Scan software available for 10.9. So unless someone else has some workaround, it seems that you won't be able to scan with this model of HP.

Block deleting DMS Document from user that is not initiator

Hi All
Hello
I Want to Block deleting DMS Document ((CV02N)
form all users that are not the initiators of the Document or
Bolcking for all user
for that I created new user authrization for CV01N,CV02N
without authorization for delete
I created a DOC in SPS (production) No 3001591
but I successed to delete the doc through cv02n
in the buttom icon for delete original
There is an option to block any user or specific form delete document ?
If there is no option for that there is an user exit that I can used ?
Thanks in advanse for your help

ORIGINAL_PATH must be a directory of application server.
By background is not possible (I don't know how can we do that) download thsi file to PC.
Then with the file in application server we can :
- to map application server directory in a drive unit of Pc
- to transfer with a ftp client from Pc
- rfcexec
But always the bapi can not download the file: it must be a process in Pc who transfer the file.

Unable to set PIN - Error: "PIN must not be the same as the user's phone number"

We are in an ongoing Lync Server 2013 deployment and have elected to set default conference PIN numbers for anyone that doesn't have them currently set. We decided to make the default PIN the same as the person's telephone extension. I realize
this is not a secure PIN setting, but please bear with me.
When I use PowerShell to loop through the people that do not have a PIN set and attempt to set the PIN to their five-digit extension, PowerShell returns the following exception:
Set-CsClientPin : PIN must not be the same as the user's phone number (Error "18005").
At line:1 char:1

+ FullyQualifiedErrorId : UserPin::SetPin::PinDoesNotMeetConstraints,Microsoft.Rtc.Management.UserPinService.SetOc
sUserPinCmdlet
I know what you are thinking: by default, Lync has the AllowCommonPatterns setting set to $false on the Global (default) PIN policy. But I have created another PIN policy called "Low-restriction PIN Policy" that has this setting set
to $true and assigned this new policy to the users I am trying to set the PIN on.
According to
Microsoft's documentation on the Set-CsClientPin cmdlet, the description for AllowCommonPatterns is as follows:
"Indicates whether or not "common patterns" are allowed in PINs.
Common patterns include repeating digits (225577); 4 or more consecutive digits (991234); and
PINs that match a user's phone number or extension number.
If set to True common patterns (such as the PIN 123456, which includes consecutive digits)
are allowed; if set to False common patterns are not allowed. The default value is False."
Given this information, I do not understand why Lync Server 2013 is preventing me from setting a default PIN that matches their extension number when AllowCommonPatterns is set to $true on the PIN policy assigned to the user.
Any ideas on what might be wrong?

My last Time Machine back-up is 45 days old and only of User Account files (not entire HD) and I must now reinstall Lion (via internet) without performing a new back-up. Will any new User Account files, since my last back-up, be lost when Lion reinstalls ?

Reinstalling OS X doesn't affect user data, provided nothing goes wrong. But it would be very unwise to assume that nothing will go wrong, especially if you're having (unspecified) system issues. You should try to back up all data before you reinstall or do anything else. There are ways to do that, even if you're unable to boot.
If your backups include only user files, you won't be able to access them in Setup Assistant.

"The CREATE USER statement must be the only statement in the batch" in SQL Azure - why? what to do?

I'm getting an error on a line in the middle of a larger sql script, only in SQL Azure.
IF NOT EXISTS (SELECT * FROM sys.database_principals WHERE name = N'foouser')
CREATE USER [foouser] FOR LOGIN [foouser] WITH DEFAULT_SCHEMA=[dbo]
GO
Error: "The CREATE USER statement must be the only statement in the batch."
I don't actually understand what 'the only statement in the batch' means.
What is a batch? Is it a SQL file? Is it related to a 'GO' statement or an 'IF' statement? What is the reason for the error? And how do I avoid it?
Thanks,
Tim

>IF...ELSE imposes conditions on the execution of a Transact-SQL statement
I understand the general purpose of an If statement. I could let go of our definition of statement counting disagreeing too except that because of the error I'm stuck.
It's less important for Create User but what I am really puzzled over now is a very similar issue how am I supposed to do a safe version of CREATE LOGIN, when I don't know whether a login has been previously created on the server or whether I
am setting up the database on a clean server?
IF NOT EXISTS (SELECT * FROM sys.server_principals WHERE name = N'foouser')
CREATE LOGIN [foouser] WITH PASSWORD = 'asdfasdf'
GO
If I try and execute this script, it throws the same error as above.
The first unworkable workaround idea is to omit the if statement
CREATE LOGIN [foouser] WITH PASSWORD = 'asdfasdf'
GO
But if the login already exists on the server (because a similar script was already run), then the script throws an error.
The second unworkable workaround idea is to do
DROP LOGIN [foouser]
GO
CREATE LOGIN [foouser] WITH PASSWORD = 'asdfasdf'
GO
Obviously this throws an error in the second block if the login doesn't already exist on the server.
The third workaround idea I have is to go conditional by putting an IF condition around DROP instead of CREATE:
Unfortunately that doesn't work for me either!
"The DROP LOGIN statement must be the only statement in the batch"
(This is despite the fact that 'drop login' is listed on the
supported commands page, not the partially supported page..?! Which disagrees with the notes on
this page.)
Anyway the real question I am interesting in addressing is: is there actually a way to have a 'Create/Delete login
if exists' operation which is SQL-Azure compatible and doesn't throw me error messages (which messes with the sql execution tool I am using)?
If there is no way, I would like to believe it's because it would be a bad idea to do this. But in that case why is it a bad idea?

AT USER COMMAND is not getting triggerd

Hi Techie's
I have two fields on the selection screen
1) Name:   ___________
2) Id:         ___________
I have some buttons say on the Application toolbar say::
Save            Delete            Modify           Exit
I have created these buttons in the INITIALIZATION event.
I am using AT Selection Screen OUTPUT for some logic purpose.
Later I am writing AT USER COMMAND and pressing SAVE The function code for SAVE is "SAV".
But the drama is that AT USER COMMAND is not getting triggered at all.
It goes first to Initialization--->At selection Screen OUTPUT>Then screen appears> I give the values and press the SAVE button--
again it goes to the At Selection screen OUTPUT.
Not even getting the hang of it. Please help if anybody know the story of it.
ITS SO URGENT.

At user command is for list processing, you need something like this:
Pushbuttons in the Application Toolbar
In the application toolbar of the standard GUI status of the selection screen, five pushbuttons are predefined with the function codes FC01 to FC05, but are inactive by default. You can activate them during the definition of the selection screen as follows:
SELECTION-SCREEN FUNCTION KEY i.
The numbering i must be between 1 and 5. The individual function texts must be assigned to the functxt_0i components of structure sscrfields before the selection screen is called. You must declare this structure as an interface work area using the TABLES statement.
If the user chooses one of these buttons, the runtime environment triggers the AT SELECTION-SCREEN event and the function code FC0i is placed into the component ucomm of the structure sscrfields.
After the AT SELECTION-SCREEN event has been processed, the system displays the selection screen again. The only way to exit the selection screen and carry on processing the program is to choose Execute (F8). Consequently, the pushbuttons on the application toolbar are more suitable for controlling dynamic modifications of the selection screen than for controlling the program flow.
REPORT demo_sel_screen_function_key.
TABLES sscrfields.
PARAMETERS: p_carrid TYPE s_carr_id,
            p_cityfr TYPE s_from_cit.
SELECTION-SCREEN: FUNCTION KEY 1,
                  FUNCTION KEY 2.
INITIALIZATION.
sscrfields-functxt_01 = 'LH'.
sscrfields-functxt_02 = 'UA'.
AT SELECTION-SCREEN.
CASE sscrfields-ucomm.
      WHEN'FC01'.
      p_carrid = 'LH'.
      p_cityfr = 'Frankfurt'.
    WHEN 'FC02'.
      p_carrid = 'UA'.
      p_cityfr = 'Chicago'.
ENDCASE.
START-OF-SELECTION.
WRITE / 'START-OF-SELECTION'.
This defines a standard selection screen with two parameters. In the application toolbar, two pushbuttons are assigned the texts LH and UA and activated.
When the user clicks one of the buttons, the AT SELECTION-SCREEN event is triggered and there the input fields are preassigned correspondingly.

Af:query saved search not getting deleted.

hi,
I have a af:query component in which I am setting saveQueryMode="default".
As per the docs, setting this value to default implies: "default: all saved searches are displayed. In addition any saved search can be created but only user saved searches can be deleted/updated."
I fire a search on the query component and then save it as "mysearch".
I then try to personalize it.
However, here I don't find the Delete button enabled for it.
I want the user saved searches to be deletable.
Am I missing anything here?
Thanks.

Simo,
I guess you have to look for MDS or Meta data service. MDS stores changes to the ui like table layout and query state for each user in a central store (db or file).
To use MDS you must use ADF security as this gives MDS the user ID.
I can't search for more info right now as I'm not in front of my pc. Check the doc for MDS and you find more info.

Your Solid State Drive and having enough space inside your Macbook Air & Pro
Solid State Drive usage premise, or the “more space / upgrade SSD” question
There have been questions posed and positions taken by many people who are trying to use their Macbook Air or Pro’s solid state drive (SSD) as a mass media storage device, for either pictures, videos, massive music collections or all three combined; but this should not be the working premise of a ‘limited’ SSD and its use.
In which, it’s the case of those users with either 128GB, 256GB, or even 512GB of internal SSD space, that have or are running “out of space”, that questions are raised. The immediate premise of some users can sometimes be “(how to / if) upgrading my SSD” when in fact in nearly all instances another approach is the logical and sensible one that needs to be looked into and exercised.
Any Macbook containing a SSD should be idealized as a ‘working platform’ notebook containing all your applications, documents, and weekly or bi-weekly necessary files. All collections of media files such as pictures, music, and videos, unless directly needed should be kept off the notebook and on an external hard drive or likewise. While the ‘working platform’ premise is also the case with larger internal conventional hard drives of 1TB+, its implementation isn't as critical except in terms of data protection.
Realistically, you should at most coordinate roughly 20 to 25% of your total SSD space to all audio-video personal use media (picture / music / video collections), leaving the remaining amount on an external HD.
Nobody should consider any notebook a data storage device at any time under any circumstance, rather a data creation, sending, and manipulation device; and in the case of a SSD, this is more important for purposes of having sufficient working space on the SSD and reducing SSD ‘bloat’ in which cases someone is wrongly attempting to use the SSD space as a large media storage nexus.
The rare exception to the collective usage and premise of SSD use in which a much larger SSD is truly needed are for those in video and photography professions that require both the extremely fast speeds of the SSD and the onboard storage for large and or many video and photography files. However this also falls under the premise of a ‘working platform’ for such peoples rather than the intent of many who are using the SSD as passive and static data storage for media files very infrequently needed or accessed.
All on-notebook data collections should be logically approached as to necessity, and evaluated as to whether it is active or passive data that likely doesn’t need to be on the notebook, allocations of space-percentages to as-needed work and use, apportioning space for your entertainment media, and questioning whether it should it be on the notebook for more than short-term consumption.
Considerations should be made in the mind of any user in differentiating the necessary system data (System hub) comprising the Mac OSX, applications, necessary documents that both must and should be on your internal SSD, and that of the users personal data (Data hub) comprising created files, pictures, music, videos, PDF files, data created or being created and otherwise, that likely unless being used soon or often should be parked on an external hard drive for consumption, or temporarily loading onto the internal SSD.
You both can and should purchase whichever SSD size you need or see fit, but even in the case of the largest of SSD, unless use-considerations are made, and SSD spaces are allocated as should be the case indicated above, one can easily and immediately run into this quandary of “needing more internal SSD space”, in which instance a different approach in usage must then be implemented.
However it is almost always the case, that such large media files are wanted to be stored internally rather than actually needed, in which case the external HD is both prudent as well as necessary. Additionally costs per MB are infinitely less on an external HD than an internal SSD in any consideration of data expansion needs.
A Professional Example
In the case of a Macbook Air or Macbook Pro Retina with ‘limited’ storage on the SSD, this distinction becomes more important in that in an ever rapidly increasing file-size world, you keep vital large media files, pics, video, PDF collections, music off your SSD and archived on external storage, for sake of the necessary room for your system to have free space to operate, store future applications and general workspace.
You should also never be put in the position of considering “deleting things” on your Macbook SSD in order to ‘make space’. This is especially what your external HD is for.
Professionals who create and import very large amounts of data have almost no change in the available space on their notebooks internal SSD because they are constantly archiving data to arrays of external or networked HD.
Or in the case of the consumer this means you keep folders for large imported or created data and you ritually offload and archive this data for safekeeping, not only to safeguard the data in case your Macbook has a SSD crash, or gets stolen, but importantly in keeping the ‘breathing room’ open for your notebook to operate, expand, create files, add applications, for your APPS to create temp files, and for general operation.
Slim USB3 1TB external hard drive
External Hard Drives
External hard drives are both extremely cheap and regardless of the size of your internal SSD (or even internal hard drive if the case), you need an external hard drive with your SSD equipped Macbook for several reasons:
1. Data backup and protection.
2. Redundancy for important data.
3. Necessitated ideal space for large media files for collections of pictures, videos, and music etc.
While ever changing in price, typical portable 2.5” external hard drives in USB3 run roughly $65 for 1TB or $120 for 2TB small portable USB3 hard drives. Such drives range in thickness between 5mm and 15mm, with recent improvements in storage of 500GB drives in 5mm profiles.
There is almost no premise in which a small 12mm thick 1 Terabyte USB hard drive cannot be taken along with any Macbook as an external large storage extension inside any Macbook carry case or pouch. Typically such external HD profiles are not much bigger than a deck of cards.
External hard drives are a foregone necessity for purchase with any Macbook for at the very least Time Machine backups, data redundancies, and ideally for large media storage.

Read committed isolation level must not produce nonrepeatable read

Hi,
I am sql server DBA. But i am trying to improve myself in oracle too.
I read isolation levels in oracle. And it says, In read committed isolation level , oracle guarantees the result set that contains committed records at the beginning of reading operation.
İf it is guaranteed , how does nonrepeatable read can occur? It must not occur then.
I think , I misunderstood something .
can you explain me?
Thanks

See the 'Multiversion Concurrency Control' section in the database concepts doc. It discusses this and has a simple diagram (can't post it) that shows it.

As a query enters the execution stage, the current system change number (SCN) is determined. In Figure 13-1, this system change number is 10023. As data blocks are read on behalf of the query, only blocks written with the observed SCN are used. Blocks with changed data (more recent SCNs) are reconstructed from data in the rollback segments, and the reconstructed data is returned for the query. Therefore, each query returns all committed data with respect to the SCN recorded at the time that query execution began. Changes of other transactions that occur during a query's execution are not observed, guaranteeing that consistent data is returned for each query.
Statement-Level Read Consistency
Oracle Database always enforces statement-level read consistency. This guarantees that all the data returned by a single query comes from a single point in time—the time that the query began. Therefore, a query never sees dirty data or any of the changes made by transactions that commit during query execution. As query execution proceeds, only data committed before the query began is visible to the query. The query does not see changes committed after statement execution begins.

The first sentence is the key:

Oracle will only query data AS OF that SCN that was determined.
If you now rerun the query Oracle repeats the process: it determines the SCN again which could be newer if other users have committed changes.
That second execution of the query may find that some rows have been modified or even deleted and that new rows have been inserted: nonrepeatable read.
If you use the SERIALIZABLE isolation level then that second query will use the SCN that was determined at the very START of the transaction. For the simple example above it means the second query would use the SAME SCN that the first query used: so the same data would be returned.
Table 13-2 in that doc (a few pages down) lists the isolation levels

Read committed
This is the default transaction isolation level. Each query executed by a transaction sees only data that was committed before the query (not the transaction) began. An Oracle Database query never reads dirty (uncommitted) data.
Because Oracle Database does not prevent other transactions from modifying the data read by a query, that data can be changed by other transactions between two executions of the query. Thus, a transaction that runs a given query twice can experience both nonrepeatable read and phantoms.
