Blob data and upgrade

I'm going to be upgrading from Oracle 9 to 10 (or possibly 11), and we have a lot of BLOB data. Is there any thing that I should be aware of? I actually am going to do this on a new system, so I'll install 10 or 11, and then put the data over (please feel free to comment on that).
Thanks,
Victoria

Pl post full source/target database versions, along with source/target OS versions. There should be nothing specific you need to do for BLOBs. If the source and target OSs are binary compatible, I assume you can copy over the database files and upgrade the database. If they are not binary compatible, you will need to use exp/imp to upgrade the database.
Pl see the 11g Upgrade Guides for more information

BLOB data and SQL Loader

Has any one used SQL Loader for BLOB data? I would think you can only use it for text type data.
Thanks,
Vic

If each blob is in a separate file, then you should be able to use LOBFILES to load them. Each row in the data file would need to have the name of the file containing the blob for that row. File ulcase9.ctl in the demo directory shows an example of using LOBFILES to load a lob column.
If you want the blob in the data file, then the data file needs to use types that have include length information in then, such as VARRAW, LONG VARRAW or VARRAWC. Also, the records for the data files cannot be terminated by a character string or newline. That's because the blob data might contain the character string or newline in the middle of its data. Instead, you would need to use the VAR record type.

Backed up data and upgrading itunes

I've backed up my ipad to itunes. Apple erased and updated my ipad to enable icloud.Went to restore ipad from itunes but it says itunes must be upgraded sync now. Will upgrade lose my backed up data?!

My oh my, slightly exceeds your lifespan.. three score and 10 or if you are strong four score..81,000 years hmmm..
Are you using Lion.. 10.7.5 to be exact .. you are subject to a serious bug, created by Apple and not fixed before release to all computers.. great the level of testing Apple does now.. think of yourself as a beta tester..
Here is the patch to update to the patch.
http://support.apple.com/kb/DL1599
If you are on a different OS tell us.. ML can have similar if not quite so bad issues.
The bug may have corrupted the old backup which is why it needs to be replaced. Unfortunately once it restarts the backup I doubt you can recover what was there.. it seems your backups now need backups if there happened to be anything you actually want.
I strongly recommend at the moment getting another software backup program.. superduper, CCC, chronosync.. something designed to create a single image.. and not self corrupt.

Oracle 01g and forms 6i with BLOB Data type

Dear All,
I have upgraded my database from oracle 9i R2 to oracle 10g R2. i have an application developed using oracle forms and reports 6i. this application have a form where it stores and retirive an image from the database, this image is stored in a table with a BLOB data type, it was being retrieved fine until we did the upgrade and now it is impossible for me to see the image and i am getting an error every time i retrive the data. it always pop a message saying that "INCONSISTENT DATA TYPE"
please guys help.
Regards

you can try this procedure
DECLARE
t_blob BLOB;
t_len NUMBER;
t_file_name VARCHAR2(100);
t_output UTL_FILE.file_type;
t_TotalSize number;
t_position number := 1;
t_chucklen NUMBER := 4096;
t_chuck raw(4096);
t_remain number;
BEGIN
-- Get length of blob
SELECT DBMS_LOB.getlength (PHOTO), ename || '_1.jpg'
INTO t_TotalSize, t_file_name FROM DEMO WHERE ENAME ='moon';
t_remain := t_TotalSize;
-- The directory TEMPDIR should exist before executing
t_output := UTL_FILE.fopen ('TEMPDIR', t_file_name, 'wb', 32760);
-- Get BLOB
SELECT PHOTO INTO t_blob FROM DEMO WHERE ENAME ='moon';
-- Retrieving BLOB
WHILE t_position < t_TotalSize
LOOP
DBMS_LOB.READ (t_blob, t_chucklen, t_position, t_chuck);
UTL_FILE.put_raw (t_output, t_chuck);
UTL_FILE.fflush (t_output);
t_position := t_position + t_chucklen;
t_remain := t_remain - t_chucklen;
IF t_remain < 4096
THEN
t_chucklen := t_remain;
END IF;
END LOOP;
END;
it will work

I just got iphone 5c and i am not happy with it. It uses to much data and i don't even know how. I can't get the ringtones i want for my contacts.I got it on my free upgrade but i want to take it back and get something else but where i got it they say i c

I just got iphone 5c and i am not happy with it. It uses to much data and i don't even know how. I can't get the ringtones i want for my contacts.I got it on my free upgrade but i want to take it back and get something else but where i got it they say i can't because i don't have the earbuds and i have serches or them. now i am suck with a phone i don't like at all until my next upgrade. this is very dishearten

1. If you are this unhappy with that phone, and the lost earbuds is the only thing stopping you from taking it back, why do not just buy some earbuds. That way you can get rid of that phone. It all depend upon how much you want to get rid of that phone.
2. Yet if you are stuck with that iPhone, here is something might help you to control the data usage. By design, iPhones do turn off WiFi when they go dormant. So if a download is in progress and so forth when the phone goes dormant, it will switch to use cellular data, if this setting is left on. Therefore, from multi-sources I have learned that if you keep your iPhone connected to a power source, then it will stay connected to the available WiFi.

If you have unlimited data and plan to upgrade "BE WARNED"

This is just an FYI to all those who may fall into the trap I did. I wish I had know about this prior so I would have made my choices accordingly.
VSW has changed the upgrade plans for those with older unlimited data plans. If you use a line upgrade to get a smartphone that line not only gets the 24 month contract but you will also be forced into a min of $30/month data plan.
I have 3 phones on my account. 1 of them have unlimited data and the other two are simple flip phones (no data).
For 3 years I have used one of these non-data plan lines to upgrade the smartphone and then would move the phone to the unlimited line and the flip phone back to the non-data line. This worked great as my 2 non-data lines had contracts that ended on opposite years.
This last time I upgraded, In January, I explained to the sales person what I wanted to do, they told me they do this all the time and they would take care of it.
My Feb bill was a bit higher than I expected so I called support. I showed them the $30 data fee and how I did not want this on a flip phone. They stated oh yes we understand, will fix it and credit you. Perfect I thought. Sure enough March's bill came and the credit was there but the $30 data charge had not been removed. I called support again and this time they dropped the hammer on me.
My credit was an "Inconvience" credit, it was a range of $3-$8 per line, it was not a reversal of the $30 data charge. This is when I find out that VZW has now changed thier smartphone plan upgrades for accounts who are on grandfarthered in plans. If I switch to thier current plan, ie lose my unlimited data then they are more than happy to remove the data charge. So now I'm stuck paying $30 a month for the next 22 months = $660 in charges for something I will not use. A full contract 24 months $30/month is $720 which is more that the cost of most smartphones.
If this is your situation please be sure you have all the facts prior to getting tricked into a contract worth more that the darn phone you get for "FREE!!!!"

According to VZW support this was a policy change in 8/14, 7 months ago(ish), I'm not claiming this is brand new but I am telling others who have been with VZW for many years and still like the less expensive package they have had for those many years need to be aware that this is the rule now. In attempts to force those long term customers to go to a more expensive plan that offers far less service they have implemented this.
I do understand this policy now and certainly will no longer use the upgrades however I wanted to offer my story as a heads up to any other potential person from running into this situation.

How can I get missing contacts, notes, calendar dates and reminders that are just on my old iphone onto the iCloud for transfer to my new iPhone upgrade?

Dear wise & wondeful people:
How can I get missing contacts, notes, calendar dates and reminders that are just on my old iphone onto the iCloud for transfer to my new iPhone upgrade? Half of my contacts, notes, ect. were on my iCloud so have happily moved to my new iPhone but the rest are completely resistant. For example, on my iCloud I have 14 missing contacts starting with the letter A alone, however they are happily viewable on my old iPhone 4S and won't budge over into the iCloud.
There are also 3 notes missing yet still acessible on my onld iPhone 4S, the list goes on.
Your help would be most appreciated. Thank you so much.

ICal lost end dates and ∞ sync conflicts after iOS4 upgrade

   After upgrading my sacrificial iPod 3 (I’m waiting to upgrade my main iPhone 3GS) and synchronizing it to my home MacBook Pro 2007 17", I got huge numbers of old repeating meeting which seem to have lost their end-date, e.g., “Palm-size PC Porting Lab” on June 28th this millennium, which I assure you is an error. I restored from a desktop backup, overwrote the iOS4 Calendar data, and synced again.
   After that, I had a miserable day full of a dozen or so Resolve Sync Conflicts dialogs—sometime three or four in a row after a single, very slow, sync. Several times two sync processes used up all my real memory (using over a gigabyte, out of three) and once it even used up all my disk space (I had 29G free). I also had a few rounds of conflict on my work MacBook Pro 2009 13", synced via MobileMe.
   Some historical notes: My calendar data is quite large, going back to Newton days via PalmOS, and iPhone OS 3 never handled it properly, e.g., both search and over-the-air sync are broken on my 3.1.3 iPhone. MobileMe sync data also gets corrupted every few weeks. And “Palm-size PC” was Microsoft’s court-ordered renaming of their trade-mark infringing Palm PC.
Macaulay‘s Law of Software Upgrades:
“To think nothing of symmetry and much of convenience; never to remove an anomaly merely because it is an anomaly; never to innovate except when some grievance is felt; never to innovate except so far as to get rid of the grievance.”

Deleting my caches per http://support.apple.com/kb/TS2481, and restoring and rebooting a couple of times, seems to have shut up the warnings, at least for now, but there's still some data loss, e.g., two meetings on 6/21 and 6/22 don't show up any more on my main Mac, but do show up on both my sacrificial iOS4 iPod, and my real 3.1.3 iPhone. (I’m also having trouble with a Note failing to sync from my iPad, but I haven’t tried that yet since nuking my caches.)

I recently tried to update my iPhone 3 software via my mothers Mac book comp - during the upgrade I lost all my music and calendar dates and now the iTunes on my phone has my mothers iTunes detail - how do I get all my info back on the phone?

Restore it using the computer you normally sync with.

My iphone 5s is now a brick, i lost all my data with upgrading ios8.0.0 and ios8.01

i upgraded from ios7.1.2 to ios 8.0.0 and my wifi stoped working, it worked only few seconds in 1 minute, and my other apps start to lagg and couldn chat on them, so i was really happy when i saw new ios8.0.1 and started downloading it and tryed to install it but then all went wrong. so i lost all my data and i cant get it back, because when i try to restore my data from itunes it says restoring was incompleate... what can i do now?

Reset your device: hold down the home button along with the sleep/wake button until the screen goes black and you see the Apple, then let go. (No data loss)
If this doesn't change anything, backup and restore your software via iTunes. If the problem continues, restore as a NEW device. If this solves it, that means there is some corruption in your backup file, or maybe it's one of your apps causing the trouble. If the problem is still there, you should take it to the Genius Bar at an Apple Store for evaluation.

I just upgraded my ipad OS and now my ipad is not picking up the 3G network. Why and how do I fix this? When I go into cellular data and view account it says my ipad is activated and ready to go. What gives???

Why and how do I fix this? When I go into cellular data and view account it says my ipad is activated and ready to go. What gives???
It was working fine up until I upgraded the OS which I hadn't done in many versions so the ipad was not working as well as it should. Now it is searching for the network.
.

Hello noodles074!
Let's get your device working again! It's possible that your device just needs to be reprovisioned on our network. Please go to Settings>General>Reset>Subscriber Services>Reprovision Account. This may take several minutes. After allowing about 5 minutes for completion, please power your iPad off and back on, and test it again. Let us know if this takes care of it!
Thank you,

I upgraded to the new IOS, but lost data and apps. When I try and restore the only backup I see is the one made AFTER the lost data. How can I access an older backup from the cloud?

Why don't you talk to apple and find out if backup exists? That conversation with apple will stop your guessing.
