JPA @Version annotation with Timestamp and insert

Hi. I have the @Version annotation specified on a Timestamp field of my entity. The versioning works correctly as long as the Date is populated in the database, but when I insert an entity, I get a StaleObjectException. After some research, I found several references saying that the @Version attribute should not be set manually. So my question is: Does the @Version annotation initialize a Timestamp on insert by default, or is there some other annotation (eg - @Temporal or something) that has an attribute that specifies a default value on insert?
Thanks for your time.

I create the 3 dates in Eastern time, then change the JVM default to UTC: the 3 inserts work.
I create the 3 dates in Eastern time, then leave the JVM to Eastern time , the 3rd insert gets the unique constraint error.
To me, the PK principle is not broken: these are 3 different UTC dates.

My hard drive died last week, and I needed to install a new one. Previously, I was able to save a .doc with text and inserted photo to .pdf and then to .jpg. Now I can get the .pdf but can't determine what to do to convert to .jpg. Does anyone know ?

Rather than do that, which means starting over from scratch, losing all your edits, organisation and so on, why not simply use iPhoto Library Manager to revert the Library to the older version? Easier, less destructive.
The instructions on that are here
If you really want to start over: you can access the Originals folder simply by going to your Pictures Folder and finding the iPhoto Library there. Right (or Control-) Click on the icon and select 'Show Package Contents'. A finder window will open with the Library exposed.

Problem with overwrite and insert keyboard commands

I'm a new user, switching from FCP. I edited one project successfully with no trouble a couple of weeks ago. Now I'm in a second project and having a weird difficulty. Using a pretty new Mac 8 core tower.
The insert and overlay keyboard commands (comma and period keys) don't work. They still work in the old project but not this one. If I start a new sequence and copy my timeline to it, the commands will work for awhile but ONLY with video, not with the audio tracks. Drag and drop works fine but that really slows me down.
The clips I'm using are all the same format (H.264 from Canon 5DII and some still photos) as the first project. Only difference in this project is lots of chroma keying and some resizing of background still photos. Nothing unrendered.
I started a new project just now and imported the problem project into it, started a new sequence, copied old sequence, and I get the same problem. I can drop in video with a keyboard command but not audio. Earlier it was not even doing video. Yesterday when I'd start a new sequence and do the same thing, it would give me video on the keyboard command but then eventually that would stop and it would do nothing. At one point the cursor would move over the width of the clip, as if it had been dropped into the timeline, but then that stopped as well.
I've trashed preferences and that didn't work. I did that according to a procedure I found online. It said open up PP while holding down the Shift and Option keys. I did that twice. Nothing.
To summarize: Keyboard commands for overwrite and insert edit do not work in this project but do in an older project.
Any ideas?
Thanks.

Well, thanks to an email from another person who was having the same problem, it's all solved not.
Operator error. Dang. Who knew--in FCP you select a track by clicking on the V or A buttons to the far left. In Premiere Pro you have to make sure BOTH the far left button and the one to the right that says Video 1, Audio 1, etc. are also clicked. They BOTH have to be light gray. In my first project, everything was properly activated but in the next project apparently they were not and that carried over to succeeding projects (even though I didn't change anything...at least consciously).
So all as well now. No glitch, no bug. Just good ol' fashioned operator error. I will wear the dunce hat today.

Use of the "updlock" hint with update and insert statements

I have inherited some stored procedures and am trying to figure out why the developers decided to use the "updlock" hint on many of the update and insert statements. I have looked around everywhere and have found only one explanation of why "update...with
(updlock)" can be useful, namely when a table has no clustered index:
http://www.sqlnotes.info/2012/10/10/update-with-updlock/ I have found nothing yet that mentions why "insert into...with (updlock)" might be used. I understand why the hint
might be useful on select statements in some cases, but if all of the tables have clustered indexes, is there any good reason to use it on update and insert statements?
Thanks,
Ron

This form of deadlock error can occur on a table which has a clustered index.
If you are doing updates on a table which has a clustered index and that table also has a nonclustered index and the nonclustered index is used to find the row to update you can see this type of deadlock. For example create a table with a clustered
primary key index and a nonclustered index by running
Create Table Foo(PK int primary key identity, OtherKey varchar(10), OtherData int);
go
Insert Foo Default Values;
go 10000
Update Foo Set OtherKey = 'C' + Cast(PK As varchar(10))
Create Unique Index FooIdx On Foo(OtherKey);
That creates a table with 10000 rows, a clustered index and a nonclustered index. Then run
Begin Transaction
Update Foo Set OtherData = 1 Where OtherKey = 'C5'
That will use the FooIdx index to find the row that needs to be updated. It will get a U lock on the index row in the FooIdx index, then an X lock on the row in the clustered index, update that row, then free the U lock on FooIdx, but keep the X lock
on the row in the clustered index. (There is other locking going on, but to simplify things, I'm only showing the locks that lead to the deadlock).
Then in another window, run
Begin Transaction
Update Foo Set OtherData = 2 Where OtherKey = 'C5'
This will get a U lock on the index row in the FooIdx index, then try to get an X lock on the row in the clustered index. But that row is already exclusively locked, so this second window will wait holding a U lock on FooIdx row and is waiting for
an X lock on the clustered index row.
Now go back to the first window and run
Update Foo Set OtherData = 3 Where OtherKey = 'C5'
This will once again try to get the U lock on the FooIdx row, but it is blocked by the U lock the second window holds. Of course the second window is blocked by the X lock on the clustered index row and you have a deadlock.
All that said, I certainly do not routinely code my updates with UPDLOCK. I try to design databases and write code so that deadlocks will be rare without holding excessive locks. The more locks you hold and the longer you hold them, the more
blocking you will get and the slower your system will run. So I write code that if a deadlock exception occurs, it is properly handled. Then if too many deadlocks occur, that is the time to go back to the code to see what changes are needed to
decrease the number of deadlocks (one way to do that may be to get locks earlier and/or hold them longer.
But I wouldn't worry much about this form of deadlock. It is, in my experience, vary rare. I don't recall ever seeing it in a production environment.

PK with TIMESTAMP causes insert unique constraint error at DST switch

Hi,
I have a test that inserts rows in a table that has a TIMESTAMP in its PK.
When inserting rows that cross over the November DST change, it tries to insert these dates:
--- Sun Nov 02 02:00:00 EST 2008
--- Sun Nov 02 01:00:00 EST 2008
--- Sun Nov 02 01:00:00 EDT 2008
This is the output of 3 different UTC dates. We can see that there are 2 x 1am, but they differ in their DST. They are really 3 different UTC dates.
But I get this error:
--- Expected error: ORA-00001: unique constraint (DDLTEST1.SYS_C00142622) violated
But I can get around that error and can insert these same dates if I set my JVM to UTC. The inserts work so I suspect this to be a JDBC issue.
I am using the Oracle Thin driver in a spring app:
<property name="driverClassName" value="oracle.jdbc.driver.OracleDriver" />
<property name="url" value="jdbc:oracle:thin:@localhost:db" />
I can post the sample code but wonder if there is an obvious answer to this.
Note that MySql had the same problem. I fixed it by specifying the UTC timezone in the connection string, like this:
jdbc:mysql://[host]/[db]?useLegacyDatetimeCode=false&useTimezone=true&sessionVariables=time_zone='UTC'
Any idea how to get around that problem without setting JVM to UTC ?

Problem with SDO_FILTER combined with Timestamp and Order By using JDBC

I'm having a problem with using SDO_FILTER. I've included a test driver below. It seems that I'm having a problem with combining the SDO_FILTER, Timestamp, ORDER BY and a nested table using the Oracle 11.1.0.7.0 driver against Oracle 11g. The below query queryNoWork results in the following error:

Is the TRACK_SEGMENTS table partitioned ?
It looks like in the case where the SQL does not work, it is not using the Spatial index. So can you add some index hints
in the query to force it to use the spatial index TRACK_SEGMENTS table ?

DBMS_TYPES with timestamp and interval does not seem to work.

I have a PL/SQL script that seems to work for char,varchar,numerics, dates, but not for intervals. I basically took example code out of the Oracle manuals and stitched it together.
The code in question is the function colTypeString. Apparently, interval is not being recognized as a type, so the function is returning back unknown. The documentation seems a bit spartan, so I thought perhaps you can help me out.
Thanks.

The issue is that DBMS_SQL and DBMS_TYPES have different typecodes. Which means you can't interrogate the DBMS_SQL.DESC_REC using DBMS_TYPES constants. You could create yourself a package of DBMS_SQL_TYPES.

Version incompatibility with UCM and WLS

Dear All,
I just have some confusion.
I have installed WLS 10.3.4 and houses the Webcenter 11G PS3 (11.1.14) also.
But when I download the UCM 11GR1, I notice that it says it is not compatible with my Weblogic.
I think I have downloaded the wrong version, I am looking for UCM 11G download to match my already
setup domain but when I check the older release at OTN, i only can find Oracle Universal Content Management 10gR3 Downloads.
Is this the same or is this copatible with my WLS?
Thanks

Hi Jose,
This is a known interoperability problem with MS SOAP toolkit, which send what is refered to as untyped request. You have an option to accept untyped request in oc4j - look at section 12.2 of the 10.1.2 Web services guide [http://download-west.oracle.com/docs/cd/B14099_04/web.1012/b14027/custom.htm#BABEJDEC]. The tag is <accept-untyped-request> .
Hope this helps,
Eric

TDMS with timestamp and configurable channels

I am trying to figure out a good way to determine how to line up data in a TDMS file with corresponding timestamps when the user in my application adds channels.
Here's the scenario,
Lets say I've been recording 10 channels (called Ch0,Ch1...Ch9) in a group called 'Data'. My data appears as follows in the TDMS file:
(10 Ch's, 3 Samples)
Timestamp
Ch0
Ch1
Ch2
Ch3
Ch4
Ch5
Ch6
Ch7
Ch8
Ch9

Let's say now the user decides to add an additional channel to the group. The TDMS write function will add the channel, but the new data does not line up with the corresponding timestamp, instead it start writing to the first row as follows:
(11 Ch's, 6 samples, 3 new channel samples)
Timestamp

Other than just starting a brand new TDMS file, can anyone think of a way to line the data up with its corresponding timestamp in this scenario? Or if there is a way to determine what the corresponding timestamp is when I read in the TDMS file.
Any help is appreciated
Thanks,
-CAC

From your description that the channel values have their corresponding timestamp, I assume that you are writing the waveform data rather than those basic data type(integer, double, etc.) which do not have any timestamp related information.
The reason that the new data in Ch10 does not line up with the same timestamp data in other channels is because:
When writing data to a channel, it cannot leave the first several positions vacant, and start writing from the nthe position.
From the view of TDMS as a file format, it should only be responsible for data logging, and not assume any relationship between channels.
In your case, the new data in Ch10 channel should have the timestamp starting from 12:00:04 AM to 12:00:06 AM, these data are definitely stored from the first position of Ch10, and .tdms file format cannot do anything to line up the data between channels.

For your second question, there is a approach to determine the corresponding timestamp of each channel data read out from .tdms file. The waveform data type is stored in .tdms file in the form of three components:
Value array value[ ]
Starting time stamp t0, which is the base timestamp of a channel (or the timestamp of the first value in this channel)
Time increment dt, the time interval between two data samples. (e.g. one sample per second, dt=1.0; four samples per second, then dt=0.25)
So it's very easy to calculate the Timestamp of value[index] = t0 + (dt * index) (0 <= index < num of samples in value[])
Here is a VI in the attachment that demonstrates how to get the timestamp of each value in the channel.

Can someone help with Incompatible versions error with taglib and project?

Evening all,
I am trying to import a tag library into my web project but I keep getting the error "Incompatible versions: Tag library is version 1.2, project version is version 1.1".
I am using IBM Rational Application Developer as my IDE, Tomcat 5.0 as my target server and I'm compiling my code with SUNs 1.4.2 JRE.
I created the tag library as a java project and my web site as a dynamic web project in IBM RAD.
If anyone can tell me why I'm getting this error message and, if possible, how to fix it I would be very grateful.
Thanks in advance,
Alex

Evening all,
I am trying to import a tag library into my web
project but I keep getting the error "Incompatible
versions: Tag library is version 1.2, project version
is version 1.1".1.1 and 1.2 might be referring to the servlet spec level supported by each.
I am using IBM Rational Application Developer as myIDE, Irrelevant, I believe.
Tomcat 5.0 as my target server and Tomcat version 5 implements the Servlet 2.4 and JavaServer Pages 2.0.
I'm compiling my code with SUNs 1.4.2 JRE.That's fine.
>
I created the tag library as a java project and my
web site as a dynamic web project in IBM RAD.I wonder if all you have to do is recompile and repackage your tag library. Maybe it's an older library that has to be updated to the spec supported by Tomcat 5.0
If anyone can tell me why I'm getting this error
message and, if possible, how to fix it I would be
very grateful.
Thanks in advance,

Help with CDOSYS, and insert into DB

I'm using Dreamweaver 8, SQL Server 2000, Windows 2003
Server.
This is what so far I was able to achieve. Have a form that
inserts records into the database, a confirmation page of the
insert, and a simple CDOSYS message to notify me that a record have
been inserted.
Basically on the Form action I call the insert page, wich in
turn redirects to the confirmation page that virtually includes the
file for the email.
What I would like to achieve, is the email that I've setup,
to include in the body of the message all the fields that have been
inserted, instead of a simple message that a record have been
inserted. Below is the simple code that I´m using for the
email. Can someone explain what do I have to modify or add and
where?
Thanks.
Manuel

ps when syncing it jumps through steps 1 - 4 real fast, i seem to remeber iphone showing the number of tracks transferring and names, but i see nothing? then it sits on 5 saying "waiting for changes to be applied"

TDMS with timestamp and different tab creation

Hello all,
I would like to ask you how can I get readings from two voltage sensors and save them into .tdms format. However, as these readings will be continuous and long, I need one .tdms file for each day for management purposes. For management purposes again I'd like to have reading for each hour of the day in separate tabs.
Moreover, if convenient I'd like the date/time next to each reading (total three columns - 1. date/time 2. Sensor #1 3. Sensor #3).
I know that partial solutions to this problem are all over the place but I'm not as proficient in LabVIEW to be able to assemble this information. If you could help me I would greatly appreciate it!
Thanks in advance!
Solved!

Hi Settler,
An easy way to change the chanel name would be to generate a file path that is dependent on the current time.
I've attached a simple VI that converts a timestamp into a string of the current hour. I hope this helps.
