OptimisticLockException, no version number in identity map

A project using TopLink is getting the following exception randomly. Any suggestion on what might cause the exception?
Local Exception Stack:
Exception [TOPLINK-5004] (OracleAS TopLink - 10g (9.0.4.4) (Build 040627)):
oracle.toplink.exceptions.OptimisticLockException
Exception Description: An attempt was made to update the object
[com.ford.mss.wdmo.wiqs.business.model.VehicleConfigurationOptionEconomics
(CR Key: 0; Row Num: 0; Code: ; Desc: ;)], but it has no version number in the
identity map.
It may not have been read before the update was attempted.
Class> com.ford.mss.wdmo.wiqs.business.model.VehicleConfigurationOptionEconomics
Primary Key> [null, 0] The problem seems to occur after certain sequence of operation: update an object
in a graph and commit; update another object in a graph and commit; fails in
commit when trying to update the graph by inserting a new object in the graph.
The problem does not occur whey only trying to update the graph by inserting the
new object in the graph.
It appears that some 'empty object' (i.e. PK null, other attributes not set) got
registered in the UnitOfWork, though we have not determined how it happened.
Just wondering if anyone has experienced the exception or knows what can cause the exception...
I appreciate your comments.

Worked with the project and solved the problem.
The exception was caused by some unwanted 'empty object' (i.e. object whose PK is null) in the object graph that's registered with UnitOfWork. It appears that the cached object graph was corrupted with the 'empty object' for some user execution sequences. After removing the original source where an 'empty object' was created/added to object graph, the problem has not been seen.
Thanks.

Where can I find a mapping of the Mac Powerbook version number (e.g., 3.1) to the dates (e.g., "late 2007") that Apple uses for indicating compatibilty with OS upgrades?

Where can I find a mapping of the Mac Powerbook version number (e.g., 3.1) to the dates (e.g., "late 2007") that Apple uses for indicating compatibilty with OS upgrades?

There were no PowerBooks made in 2007. By then Apple had switched over to Intel and they were making MacBook instead.

Powershell update Field Value without changing version number

I want to update a value in a field in a list for a lot of list items.
However, this list has major and minor versioning turned on, and an approval process.
When I update the field's value for all the required list items, I don't want the approval process to start and I don't want the version number to change.
How can I do this?
This is my code so far:
$siteUrl = "http://portal"
$listName = "list name"
$field1_Name = "category"
$web = Get-SPWeb -Identity $siteUrl
$list = $web.Lists[$listName]
$items = $list.Items
ForEach ($item in $items)
    if ($item[$field1_Name].ToString() -eq "testing")
$url = [String]::Format("{0}/{1}",$web.Url, $item.File.URl)
    $file = $web.GetFile($url)
$file.CheckOut()
write-host $item.name
       $item[$field1_Name] = "testing again"
       $item.Update()
$file.CheckIn("updated category name", [Microsoft.Sharepoint.SPCheckinType]::MajorCheckIn))
$web.Dispose()

Instead of calling $item.Update() call $item.SystemUpdate($false); That will update the fields without incrementing he version number of the listitem. Read about it here:

AppManifest.xml is being generated with the wrong version number

I am having a interesting problem which is preventing me from submitting an update to my app to the Windows Phone Store. I have done this 100 times and something is wrong with visual studio building the .xap file. Steps I am taking:
Update all version references in project settings and appmanifestWM to 1.4.0.0
Build Release version
Copy .xap from /bin/release
Upload as an app update to windows phone dev site
What happens is that the current version of the app (1.3.1.0) is still listed as the version of the app that the submission page is parsing out of the version (1.4.0.0) .xap file. I unzipped the xap file and looked at the appmanifest files and found that
the AppManifest.xaml has the correct version number but the AppManifest.xml still has version 1.3.1.0. If anyone could help me resolve this issue it would be greatly appreciated.

Thanks for your reply. I believe it is a bug with my solution because I have now tried all of these steps on two computers and uploaded using two different browsers and I still get a AppManifest.xml file that has version 1.3.1.0. I will copy and paste the
unzipped code from the AppManifest.xml file.

As you can see the package version being generated is wrong. Can you explain where exactly in the solution that value is taken from? I thought it was from WMAppManifest but I could be wrong.
Edit: In looking at the code above and then rereading what I wrote I realized my blaring error. I completely forgot that Silverlight 8.1 apps have an appxmanifest as well and that data is drawn from that as well as WMAppManifest. I never updated the version
in that appxmanifest. Thank you for the help and I apologize for my stupidity.

Object Version Number column

Hi all,
In the OAF dev guide,they have given some information on object version number column which can be used to store the version of the row data entered.
This can be achieved by mapping a attribute to ObjectVersionNumber attribute.
I tried mapping it i didn't see any attribute with the name ObjectVersionNumber in the BC4j EO wizard.
Can somebody please give more information on this
And do correct me if i gone wrong somewhere
Thanks in advance
Ashwini

Another use of this column is to maintain the history record. So each time you update the record, another record with same primary key, but with an increased OVN.

Number of class maps (QOS) supported on 7200 and 7600

Hi,
Have few queries on class maps for QOS, putting forward for your comments/inputs.
1. Want to know if there are any limitation (s) on the number of class maps (to be applied inbound/outbound) that can be configured on the 7200 and 7600 routers.
2. Is there any imitation on the numbers (of class maps) in general or will it depend on the sum total of BW configured in the classes? I mean which one will be the deciding factor i.e. if the limit is wrt to the configured classes or the number of classes can't go beyond the consolidated bandwidth configured on the interface.
Kindly share details on the same and if there are any recommendations.
Thanks! in advance.

From: http://www.cisco.com/en/US/tech/tk543/tk545/technologies_q_and_a_item09186a00800cdfab.shtml
"Q. How many classes does a Quality of Service (QoS) policy support?
A. In Cisco IOS versions earlier than 12.2 you could define a maximum of only 256 classes, and you could define up to 256 classes within each policy if the same classes are reused for different policies. If you have two policies, the total number of classes from both policies should not exceed 256. If a policy includes Class-Based Weighted Fair Queueing (CBWFQ) (meaning it contains a bandwidth [or priority] statement within any of the classes), the total number of classes supported is 64.
In Cisco IOS versions 12.2(12),12.2(12)T, and 12.2(12)S, this limitation of 256 global class-maps was changed, and it is now possible to configure up to 1024 global class-maps and to use 256 class-maps inside the same policy-map."

After Active Directory System Discovery, some computers have Operating_System_Name_and0 as only the version number

Good morning,
We've been experiencing some odd behavior with discovery. After Active Directory System Discovery, some computers have Operating_System_Name_and0 as only the version number; for example, " 6.1" (note the space before the 6) vs.
"Microsoft Windows NT Workstation 6.1" (although, not limited to Windows 7 workstations).
Here are two seemingly identical machine records in Active Directory WCBWIN7VDI10 and WCBWIN7VDI11.
After discovery
select Name0, Operating_System_Name_and0 from v_r_system where Name0 LIKE 'WCBWIN7VDI1[0,1]'
yields
Name0 Operating_System_Name_and0
WCBWIN7VDI10 6.1
WCBWIN7VDI11 Microsoft Windows NT Workstation 6.1
For discovery on a new domain yesterday we have the following distribution:
select count (*) as [count], convert (nvarchar, Creation_Date0, 110) as [creation date], Operating_System_Name_and0
from v_r_system where Full_Domain_Name0 like 'aaa.bbb.ccc'
group by Operating_System_Name_and0, convert (nvarchar, Creation_Date0, 110)
order by Operating_System_Name_and0
count
creation date
Operating_System_Name_and0

Hi Terence,
What is the value in Active Directory for the computer account?
Do you have the same behavior if you run this query?
SELECT DISTINCT Operating_System_Name_and0 FROM v_R_System ORDER BY 1
You are talking about a space before 6.1. Do I see also a space for all Microsoft Windows like "Microsoft Windows NT Workstation 6.3" ?

PO Ammendment and version number

Dear Experts,
We have version management active at out client.
When we save the PO after changes version number is generated and changes are saved against that version number.
We want the report where we can see the Ammendment details in the PO , that is changes thet were made in that particular PO.
What are the tables and which are the fields where we can find these details.
Is there any standard report available where i can see those changes in PO.
Pl. guide.
Best Regards,
Vikram

Hi
I dont think standard report is there to show versions created in purchase orders.
You can use the table EREV, doc type F which shows version numbers with status active or completed..
Thanks

I am new to Teststand software interface. While doing my first software release under the guidance of a more experienced colleague, we discovered that Teststand will not run if it detects version number conflicts between custom data types on my machine vs. the production test machine. I verified differences between all .seq files in my test program directory, but I did not realize that the version number difference exists in the StationGlobals.ini file, which is stored in a different location. After discovering this, I modified the version number in one of the files. However, two releases later, I discovered that the version number mismatches in another two files. This raises several questions for me :
1. Is there a way in Teststand to view all the .seq files where a custom data type is used and then change its version number in one attempt?
2. Under what instances does Teststand upgrade the version number of a custom data type?
3. Are there any tools or scripts within Teststand that can allow the version number of custom data types to be changed in all .ini files when a difference is discovered between the current production test station settings and a new release?
Please help.

Have you read this? http://zone.ni.com/devzone/cda/tut/p/id/7060
I can tell you that your situation is not uncommon with TestStand. The key is just doing it right the first time. haha
#1- I doubt that this is possible because then TestStand would have to know every location of every .seq on the machine. You will only see it when you open the sequence file.
#2- TestStand updates the version every time you change it. You should get a message popup when you try to save that asks if you want to increment the version or not. There's also a check box that says Remove Modified Mark From Types. Look under Station Options in the File tab. There are some settings there about Type conflicts.

The same Object Version Number for the same person id multiple times

Hello all,
I am currently facing an issue with HRMS tables and the object version number for employees. I am trying to write a report but due to the same object version number for the same person appearing in several row i am getting duplicate information. For example,
person id 91 object version number 32 is on 4 rows and i have no idea why...help please guys, I'm at a lost so far 50 people are facing the same issue.

Hi Baal666bobo,
The person table is date-tracked, so the PK has effective start and end dates as well.
Get the correct record with sysdate(or any particular date) and then check the OVN.
Cheers,
Vignesh

Where is the EXACT version number shown? Where is the menu link to the Help file? Why is there no scroll bar? The new iTunes is terrible in more ways than I can list... how do I switch back to version 10?

The newest iTunes version has no Help option. Why? And, no ability to find out the version number.
The new iTunes, when in album view in Windows 7, has NO SCROLLBARS, so it is impossible to scroll the albums. Why?
Answer these questions, as I am an AAPL shareholder and I am NOT happy with these and other changes you've made to iTunes.

You may need to bring up your Menu Bar to see the Help menu.
If you're using 11.0.x, click on the wee boxy icon up in the top-left corner of your iTunes to see the "Show Menu Bar" control, as per the following screenshot:
Once you've got your Help menu showing, go "Help > About iTunes" and wait for the version number to scroll up from the bottom of the screen, as per the previous versions.

How Do I Find Out a Folio Version Number

Hi Guys,
So far, everytime I have submitted a folio to the App Store, I have received a variation of the following error:
Version Mismatch - Neither CFBundleVersion ['3.4.2.9.91210'] nor CFBundleShortVersionString ['1.0.8'] in the Info.plist match the version of the app set in iTunes Connect ['2.0'].
I'd like to be able to put the correct version number into iTunes Connect when I upload the App, but how do I find it? Where is the CFBundleShortVersionString for each folio located?
Cheers
Chris

It isn't necessary to change that number—Apple is just giving you a housekeeping warning—but if you really want to edit the version number in iTunes, you can find it in DPS App Builder.

How can I set a version number for an AppleScript application?

Subject kind of says it all... I've written a small application in AppleScript, which is used on several computers. I'd like the application to have a version number, just like normal applications have. How do I give it one?
To be clear, what I mean is: in column view, if you click once on an application, it shows the icon, name, size, version, etc. of the application. I want a version number to show up there (and in the Get Info window, etc.)

Posting to this old post, but I am trying above method on my 10.8.2 machine and it doesn't seem to work.
I added the bundle version string as in the attached image.
Recompile my app, saved it but still version info doesn't show up in finder.
Also, tried to change "Bundle version" to "CFBundle version". But still didn't work.
Any suggestions?

I have never had to enter a password to access mail. However, recently, I keep being asked for password on my ****** address. Only on my macbook. (which, btw, has a version number the drop down doesn't offer as a choice. I had to putt 9.4)

When I look up the account the "password" is a long string of gobbledygook. Something I would never do.
But when I attempt to use that pw I still can't get in.
I have no trouble accessing that email account on my mac mini. Just on the macbook.

Maiko,
I'm confess I'm still trying to get a handle on your problem. You do a fantastic job of describing it ... but I'm just trying to picture it accurately in my head.
I think, were I in your shoes, I'd begin by looking at what the debug page has to say for the specific destination in which you're interested in fixing. In other words, I'm not clear on where, exactly, this destination points ...
Destination illinois.edu.1945806043
Is that your site, or the division within your site that you want to fix? "Normally", you do not need to specify a site handle to get to your site within your transfer CGI ... if you say "uillinois.edu", it's enough to transfer your users to iTunes U ... but every site still has a handle, and you could, if you wanted to, actually specify it in your transfer CGI. For example, this:
Destination uic.edu.1139051993
is for my entire site ... it's my site handle. Whereas this:
Destination uic.edu.1991288441
is for a division within my site ... but it's impossible to tell the difference between "site" and "division" from just the handle (I mean, if I didn't say "this is a site" and "this is a division", there'd be no way for you to know). So when I look at your creds and permissions on your debug page, I can't quite tell if they give you download access for your site, or for the specific division you want to fix. If you could open the debug page with your division as destination (or confirm that that's what we're looking at), it'd rule out some things.
