How do I work around a JDBC driver "unsupported function"?

We have a JDBC driver to a Unidata [multivalue, a truely interesting concept] database. It does not support setMaxRows(). The 10.1.3dp3 version throws an exception:
Internal Exception: java.sql.SQLException: setMaxRows(int) not supported by eTools JDBC.Error Code: 0
Query:DataReadQuery()
     at oracle.toplink.exceptions.DatabaseException.sqlException(DatabaseException.java:280)
     at oracle.toplink.internal.databaseaccess.DatabaseAccessor.basicExecuteCall(DatabaseAccessor.java:567)
     at oracle.toplink.internal.databaseaccess.DatabaseAccessor.executeCall(DatabaseAccessor.java:442)
     at oracle.toplink.threetier.ServerSession.executeCall(ServerSession.java:453)
and our application fails.
The driver maker suggests the JDBC spec says the function must be present but it may throw an unsupported exception.
And toplink does not appear to handle the unsupported exception gracefully.
So we appear to be stuck between the rock and the hard place.
Any help would be appreciated.

We can add setFetchSize to the list of work arounds required.
Internal Exception: java.sql.SQLException: setFetchSize(int) not yet implemented by eTools JDBC.Error Code: 0
Query:ReadObjectQuery
     at oracle.toplink.exceptions.DatabaseException.sqlException(DatabaseException.java:280)
     at oracle.toplink.internal.databaseaccess.DatabaseAccessor.basicExecuteCall(DatabaseAccessor.java:567)
     at oracle.toplink.internal.databaseaccess.DatabaseAccessor.executeCall(DatabaseAccessor.java:442)
     at oracle.toplink.threetier.ServerSession.executeCall(ServerSession.java:453)
     at oracle.toplink.internal.queryframework.DatasourceCallQueryMechanism.executeCall(DatasourceCallQueryMechanism.java:117)
So the question becomes, in general, how does one indicate to toplink that the driver has unsupported functions and it should (a) ignore them or (b) deal with it.

I upgraded my macbookpro hard drive to 1 TB then migrated my files from time machine. I'm now locked out of the computer because the password is not the same as my usual one and one that was years old and not retreivable. How do I work around this?

Whether or not you are able to recover the data off the drive yourself will depend on if the drive suffered any impact damage in the crash. You can buy USB SATA or IDE adapters (Intel and almost all G5 use SATA) that will let you connect your hard drive to a computer (like a flash drive) to see if you can recover the data. If the drive has suffered physical damage if may not mount.
If you know someone who has one of these adapters you could try using theirs, otherwise you could buy one but you take the risk of the data on the drive being non recoverable. Regardless, both are much cheaper than $1699!
(Alternatively, if you know of someone with a Mac Pro or PowerMac G5 they may be able to install the drive in their machine and try to boot from or mount it and copy the data off.)

How to know which type of jdbc driver used in my application

How to know which type of jdbc driver used in my application.

My approach will be....
Type1: you have to have ODBC s/w install on your machine...even the connection string starts with jdbc:odbc....so it can be identifed easily
Type2: you have to install client s/w in your machine...if you are using oracle oci driver ...you need to install oracle client s/w
Type3: you use servername / port to connnect to middleware
Type4: you do not need any client s/w
So, If your application works without any client s/w on your machine....you might be using Type4/Type3 driver.....otherwise Type2
Someone pls add more ....

I had been getting this all morning and checked other messages from the community. THe one which worked was trying a different brand of disc.
I had been using Verbatim which had copied the music fine off the Real Player on my PC at school, but wouldn't work with I Tunes. Tried a Staples and an Office Depot CD-R , both of which did the job.

Itunes 11.1.5 will not sync new apps with iPhone 5 iOS 7.0.6 and gives grayed out "install" no message? How does one work around this?

Itunes 11.1.5 (MacBook Pro,OS 10.6.8) will not sync new apps with iPhone 5 iOS 7.0.6 and gives grayed out "install" no message? How does one work around this?

Just reboot your laptop... While its rebooting try to reboot your phone also by holding the home and power buttonn for 10-15 seconds...When your phone is turned off try to connect it to iTunes and it will recognize your phone in recovery mode.
If you have the .ipsw file for iOS 7.0.6 saved in your desktop then in itunes press shift and click on Restore.
Select the ipsw file and let it restore.
If you dont have it downloaded then simply click on restore.
I hope it works
Cheers !

That is wrong advice and you appear to have repeated it all over the forum.
All Pages files no matter what version have the same file extension, .pages, despite being radically different formats and that is the problem. The System does not distinguish between them when you double click on the file, it opens the first version of Pages it encounters.
You need to right click on the file and choose the correct App version for the file. Unfortunately there are no clues to tell you which is which.
If you are unhappy with this and the removal of over 100 features plus the problems with transmitting files across devices, servers and different versions of OS X, rate/review Pages 5.5.2 in the App Store.

This article, from the FAQ list at the top of this forum, is valid for all versions, since it may be a problem for any.

The problem is not so much with Premiere Elements as it is with challenges faces in the operating system registry. Basically, DVD burner programs, like Nero, which are installed on your computer at the factory, refuse to share access to the DVD burner with other programs.

Work around to get Drive files to display thumbnails in Bridge

My company recently installed Adobe Drive using a CMIS connection to Alfresco community edition (bear with me, I'm the art director not IT so I hope all that made sense) only to find out that CMIS connections don't support thumbnails and previews in bridge. I then inquired with Adobe about their DAM solution and they said that was for larger enterprises. I would like to know if anyone knows of a work around? I can't imagine we are the only company who wants to use the versioning drive offers AND maintain our workflow with bridge. Any help would be appreciated..

Hmmmm. Not so sure about that one.
Actually, it might be worth checking through the iPod + iTunesdownloads page to see if there are any useful widgets and whatnot for that there. (There's a few notes-related items showing up there too, which might work better than my suggestions about performing unnatural acts with your lyrics tags.)

How do i work around 2 different frame rates in same sequence??

hello,
a client of mine just shot a video using two frame speeds...24PA and regular 24p.
how can i get around this? so far i captured the 24PA footage using the pulldown in the FCP, and the 24P in a regular 48k capture...
i am currently editing in a 23.98 timeline, but the 24p footage looks slower...HELP!
thanks,
steve

hi kyle,
sorry, but just to elaborate on your response a little while ago here:
- i captured the 24PA footage using the advanced pulldown
- i captured the 24P footage using no pulldown
- i am editing in a 29.97 timeline now, as most of my footage was shot with 24P
please let me know your thoughts on how i should go about working with this footage!
thanks!
