Migration--Bitmap to Jpeg from Oracle8 to Oracle9i
I'm having few thousand bitmap photos stored in Oracle8 database in a Long Raw column. It's taking lot of space.
I'm planning to migrate to Oracle9i. Please advise how to convert these few thousand photos from bitmap to Jpeg format in Oracle9i database.
How are you going to store the images in 9i?
My hunch is that the only way that you could convert from BMP to JPEG inside the database would be to have the data stored as interMedia image objects. I don't know for sure whether interMedia can do that conversion, but that's the only Oracle technology I can think of that could (well, unless you want to write Java or PL/SQL code that does the conversion).

Database link from Oracle8i to Oracle9i
Hi,
I am trying to create a database link from an oracle 8i database to connect to an oracle 9i database ... When testing the connection , I always receive an error "The Database link is not active"
Notes
1- Creating a database link that connects from the same 8i database to another 8i database succeeds. This gave me the impression that it is a compatibility problem but I am not sure.
2- I changed the initialization parameter
global_names = falseand restarted the Oracle database
3- the 2 databases are on the same domain
Did anyone pass through this problem before ??
thanksWell, I was testing the database link via DBA studio and there was no ora error associated with the message.
A friend helped me to identify and sove the problem. here is what he did.
Lets assume that the oracle8i database called Ora8i
and the oracle9i database called Ora9i
and that the network domain name is OraTest.com
When i select * from global_name; on both databases
Ora8i database return ==> ora8i
Ora9i database return ==> Ora9i.us.oracle.com
We then execute the following statement on Ora9i database
alter database rename global_name to Ora9i.OraTest.com;
Testing the database link after that went fine.
Thanks -
Recover during systemcopy between Oracle8 and Oracle9
Hello!
This is my first question in a forum, therefore sorry for mistakes.
We perform a systemcopy from Oracle8 to Oracle9. If we use a Offline-Backup there is no problem. After the restore we migrate the databse to Oracle9 and everything is ok
Now we try to use a Online-Backup for this. The restore is no problem but the recovery of the database end with following error:

I don't think, that the Redologs are corrupt. Have anybode an idea, what should i do???
ThomasHello!
I don't think so. Because i got this message for every log since 89797. Every try to recover the database i got this message for the next log.
It is possible to recover a Oracle8-Databse to a Oracle9 Database during systemcopy?

How do I export 72ppi jpegs from InDesign without losing quality?
I need to export indesign files that I design to 72ppi for web without losing any quality (or as minimal as possible). Countless times I have tried different methods, but alwasy manage to create a workaround, whether it be good quality, or just readable text. ITs really the small text I have the problem with. I explain in the below video my problem in further detail. But basically, I have tried many things such as pasted from indesign to photoshop, exporting to 300ppi jpeg and resizing in photoshop, exporting to 72ppi jpeg and viewing (not good at all), exporting as PDF, opening in photoshop ticking anti alias and inputting my dimensions... how can I get this to work?? Someone please help.. I have battled this problem for to long and my boss is getting annoyed with it. We need to fix this.
Many people say to export to PDF and then open in photoshop and save as a jpeg from there.. but how can i export a PDF to 72ppi?? Please Adobe fix this issue in future editions of InDesign. Thanks in advance to anyone who can help
Here is a link to the video if yu can't view it below: http://www.youtube.com/watch?v=0uqsGnhT3gY&feature=youtu.bebec-white wrote:

You have it backwards. You export a PDF, and when you open it in Photoshop, that's when you pick the resolution. Any text in the PDF will likely be vector data, and it will be changed into bitmap data at the resolution you choose. I'll give you an example:
I placed a 300ppi image (5.7MB Photoshop tiff) into an InDesign page with three captions (12pt, 9pt and 6pt). I exported the page as two different PDFs. One was set to High Quality Print (a1) and the other to Smallest File Size (a2). A1 came in at 446KB and a2 came in at 37KB. When opened in Photoshop, I picked 72ppi as the resolution, flattened and saved as an RGB Jpeg without color profile and quality setting of 12.
The a1 jpeg was 180kb in size and a2 was 156kb, so not too far apart, considering the difference in file size between the PDF versions. If you open the jpegs in Photoshop, you will see that the size of the letter F at the beginning of the 12pt caption is nine pixels high in each, so if the problem you are having is that small text isn't readable, maybe the text is just too small to be readable at 72ppi. -
Oracle8i and Oracle9i with BWLS5.1
Hi, I need help!!!
I ve a Oracle8i and an Oracle9i connection pools in WLS 5.1
The Oracle9i connection pool is not stable, and have been told to upgrad the drivers for it. I wonder if there is any problem use connection pool to an Oracle8i and Oracle9i, without any conflicts.
Can WLS5.1 handle it? how should I do ?
Pleaaaase!
regards / John CokouloHi Sree,
Sorry, I was wrong, I found the JDBC drivers for the Oracle9i.
The JDBC pack contains the OCI and Thin drivers.
Thanks alot.

I was looking for Oracle 9i Thin driver, but could not find any!

Hi John,
WebLogic jDriver for Oracle 9i is not available for WLS5.1. Its only
available for WLS6.1SP2 and above.
I suggest you use the Oracle thin driver from Oracle to connect to the
9i
database.
when you download and install the 9i thin driver, the connection pool
can be
configured as,
weblogic.jdbc.connectionPool.O9iPool=\
url=jdbc:oracle:thin:@9imachinename:port:SID,\
driver=oracle.jdbc.driver.OracleDriver,\
loginDelaySecs=1,\
initialCapacity=5,\
maxCapacity=12,\
capacityIncrement=2,\
allowShrinking=true,\
shrinkPeriodMins=15,\
refreshMinutes=12,\
props=user=o9iusr;password=o9ipwd;weblogic.oci.min_bind_size=660
You cannot use two different OCI drivers at the same time to create
Connection pools in a single server.

Hi,
I dont know exactly what driver we use, but I know that the same driver
is
in
use for bothe 8i and 9i. And I know that the driver is old, (from 2000).
The behavior is that connection duo the 9i are rollin back sometimes,
about
30%
of all transactions are rolling back.
Thats why I ve been told to use newer drivers (9i drivers).
So, yes, I see exceptions, roll back exceptions of the transactionsthat
are
trying
to connect to the database pool.
But I wonder how to do that, and how can I see exactly what driver
we
use
now?
Please help me!!!!

John,
What driver are you using to connect to 8i and 9i? What is the behavior
you
are seeing with the pool connections, when you say pool is not stable?
do
you see any exceptions/hangs ?
Also ensure that you have testConnsOnReserve=true (on the 9i pool)
so
that
the connections get recreated if they go bad.

Re-locating metadata after migration to Aperture 3 from ACDSee photo manager
Hi all,
Do you have experience from migrating a photo library from ACDSee Photo Manager 2009 (PC-software) to Aperture 3 with relevant metadata following each jpeg picture? Specifically, how to re-locate the metadata entered to ACDSee in Aperture 3 after importing the pictures to Aperture library?
ACDSee uses XMP to embed database information in each file (MGIF, JPG, DNG, PNG, and TIF file formats). Thus the database information (e.g. categories, keywords, descripitons etc) can be embedded inside the file ... and they should be usable when using other photo libraries... but apparently not. ACDSee Photomanager apparently does not copy the database information to IPTC fields but uses some other place in the files to store it. As a result I cannot re-locate the metadata once I've imported the pictures to Aperture.
Any advises on how to use Aperture to find the "lost" metadata is appreciated.
regardsI've faced the same problem too, and am making a little progress. The most important metadata for me is the rating (I'm still working on keywords etc) and I've managed to port that to Aperture by embedding it in an unused IPTC field in ACDSee and then searching for that field in Aperture, setting the rating as I go.
Would love to hear some suggestions for setting the keywords, especially ones that don't cause Aperture to crash. -
Hi,
I would like to display jpegs from a folder, and be able to somehow scroll through them?
So far i have been able to display them by using listfolder and linking it to a for loop containing readjpeg, but this basically creates a slideshow of jpegs. I would like to control which jpeg is being displayed by having 2 buttons, one to go through the pictures, and one to go backwards. .
I hope this makes sense, I'm new to LabVIEW.
Any help would be greatly appreciated!

I migrated my software/documents from another laptop so don't have the disk to reinstall. Please help! Can't open any Microsoft Office software, like Word (for 2008), and stuck in a loop?
Whenever I select Word Microsoft Setup Assistant appears, asks for feedback, then after selecting okay (both on saying yes or no to feedback) goes on to a registration page. When I click on this it says I've already registered so I just click okay, and then move on to a update page. After this, if I click on Word, the process repeats itself.
As I said, I don't have the disk to reinstall, and can't find the Office Settings to delete as many pages have suggested I should try. Safe Boot restarting also hasn't worked... Really stuck and need Word very soon for work.
If you can help, that would be great, and feel free to ask any questions about the situation as I'm not an expert here.

Next, on both of your devices, go to Settings > iCloud and turn on contacts and select Merge. Then turn off contacts and select 'Delete form my [device]' when prompted.
Now go back to iCloud.com and select a contact (yes they will all be messed up again) and select Command+A on a Mac or Control+A on a PC to select all of the contacts. Tap the delete key on your keyboard (or right click /control click a contact and select delete).
You iPhone, iPad and iCloud.com should not be empty for contacts.
Go back to Settings > iCloud on both devices and turn on contacts again (you should not see merge this time).
Next, go back to iCloud.com and import your contacts (those exported .vcards). You can either drag and drop them into the empty contacts list in your web browser, or you can use the gear icon to import.
You cleaned up contacts should import correctly into iCloud.com and sync to both of your devices.
Good luck. -
Migration of Approved Invoices from 11i to R12
Hi All,
I am migrating all approved invoices from 11i to R12 using Invoice Interface tables and "Payables Open Interface Import" Concurrent program.But in R12 the Approval status changes and to "Required" and the Accounted status of distribution line changes to Unprocessed. We do not have the set up for approval work flow process, So the invoice should be validated by "Force Validation" by checking the ‘Allow Force Approval’ in payable options. But when I am running the "Invoice Validation" program the theere is no change in the Approval status.
Please help.
Thanks in Advance,
SubhrakantI am a newbie to Oracle Apps. I guess Oracle Apps use the "sequence" to generate the Key in the Oracle tables or is there some else mechanism.
When migrating Oracle Apps from lower version to higher version, is there any concept of setting the sequence numbers in Oracle Apps or we don't need to take care of this ie the migration handles this automatically.The migration/upgrade script/driver should take of seeded objects,
For your custom objects, you need to verify it yourself.

Migrating a webi report from one environment to another using import wizard
Hi Everyone,
Can anyone please tell me what all access should I have on my ID to be able to migrate a webi report from one environment to another environment(e.g. from development to quality).
Regards,
Neeraj SharmaHi,
To use the Import Wizard utility, you basically need Administrator, Full Control to Top-level folder, and "Add objects to the folder" and "Edit objects" for this user on the root folder.
You need the least restrictive role, because you require absolute control for content promotion between 2 entitlement systems.
the webi document is the cherry on-top, you;ll have universes, connections, folders to bring over too.
Regards,

I used migration to transfer iTunes from pc to mac book. It had me set up another user account. Now i have 2 user accounts and i have the iTunes on the wrong one. How do i get the iTunes on the original account.
In Mail Preferences/Accounts/each GMail account, set up the SMTP Outgoing Server for each account separately, going into SMTP name/edit/Advanced and specify the Username of each account. The Outgoing servers must be two different servers, authenticated by the Username and Password of each.
Otherwise, the GMail SMTP server will change the from address to that of the account where the SMTP server was setup.

I have accidentally created another account when using Migration Assistant to a new MBA. I have read that I probably should not have skipped migration in the initial set up and the problem would have been avoided but, alas, here I am. Does anyone know how I can 'migrate' all the files from one of the accounts that has been created to the other, so then I can delete it and have a single user on the computer seeing as I am the only person using it? I have read starting again, if this is the way to go, where is the best place to start 'starting again'?
Yes definitely should see it but its not coming up (I don't think) when I log out of 2nd user and into the main account. Opening finder in the 2nd account, I can obviously find the public folder because thats where I dropped all the files, but when in the main account, it can't be found. The only public folder that comes up is the folder for that account (main account) and it does not display files I'm looking for. Frustrating....
EDIT: Have found it through a round-about way but all music and photo and movie etc files have a red stop sign disallowing them from being transferred. Can you guess what the next question will be? -
How can I migrate an Aperture library from an external HDD with Mac OS Extended (Journaled, Encrypted) format?
I used to store my pictures on an external hard drive using the latest version of Aperture. Now I tried migrating my Aperture library to Photos. However, after a short moment an error message popped up telling me that "Photos was unable to make a copy of your library before preparing it. Photos does not have the necessary permissions...".
My external HDD doesn't need any permission repairs nor is the system prohibited to read from or write to it.
Thanks for any advice in advance!

i set up my new computer using the apple ID i always use, and then later migrated all my files from my old mac book to the same new one, but under a different user (same apple ID). how do i consolidate the two users on my new mac book?
Well if you use the Finder Go menu to Computer, a window opens up double click on your boot drive and then on Users folder, open the other user folder and open Public and drop your files into DropBox
When you do this it will copy them and change the permissions and user assigned to it, so log into the other user and place them into your respective normal folders.
Once you have all your files over and don't need the old user, use System Preferences > Accounts to delete it if you wish, however it's good two Admin accounts on the machine in case something bad happens in the other. Some people for security reasons on use a Standard account for most uses and a emergency Admin account.
One can still do most Admin things in Standard user. -
Is there a way to create still jpegs from video clips in iMovie?
I shot some video on Christmas day and imported them to iMovie 9.
I want to creat some jpegs from the video clips and print them as photos.
Is there a way to create a jpeg from a video clip and save the file?
Thanks for the info!
LenHere is a method for extracting a still from iMovie 09.
Are you working in iMovie and realize that certain frames in the movie would be perfect as photographs? Here is how to extract them...
*To get a still frame from an Event*, right-click on the frame and select "Add Still Frame to Project". The still will be added to the end of the current project. Right click on the still frame in the project and select "Reveal in Finder". You will see a jpeg file that is highlighted. Drag this jpeg file in the finder to the iPhoto icon on your dock.
*If you want a still from a project*, rather than an event, the process is similar, except you right-click on the frame and select "Add Freeze Frame", and it adds the freeze frame at the end of the clip rather than at the end of the project. Right-click/reveal in Finder, drag JPEG to iPhoto icon in dock.
*If you are not using iPhoto*, and just want to save to your desktop, click Reveal in Finder as above, then COPY, then PASTE to desktop.
Hint: If you do not want to clutter up your iMovie Project with stills at the end that you would have to go back and delete, then create a separate iMovie Project just for your stills, and follow the instructions for capturing stills from an Event.
Note: If you do not have a right mouse button, then control-click will work instead of right-click.
