Recover DB which don have backup and not in archive log mode

Hi
today one of our DB in oracle 10gR2 in AIX got crashed which is not in archive log and which does not have any backup. It was maintained by the Developers and they need it to be recovered. When trying to open it says message like getting error with system01.dbf needs to more recover. Can any body help me. Very Urgent... Is there any way to recover the db??
Thanks
Ram

Hello Mr.Sybrand Bakkar,
Thanks for your suggestion. Being a DBA i myself knows that without anything I wont be able to. I m just trying to get some suggestions whether is there any way to recover it or has some experts came across these situations and got some answers. When we are not able to think beyond our limit, we come to the forums and post question. I know that this is not the place to write where i can be rude, Hence please change ur perception. When i say urgent, it means that unfortunately they have messed up their DB and came to DB Team for assistance to get their data back which has to be given to their process partners and As a support team we are trying our best to recover it. Anyhow thanks for your reply and suggestion. Have a great day.
Thanks
Ram

DB backup and removal of archive log files?

I have an application that uses Oracle 10gR2 on Linux RedHat EL 4.5. The DB is fairly simple, so backing up daily or weekly by using expdp (Datapump) is fine for our needs. We have an install that uses Data Guard, which in archivelog mode is filling up the disks fast.
What is the best way to clean up archive log files in a Data Guard configuration? I have seen posts that indicate RMAN is tough to work with and has problems with recovery, so I would rather avoid it.
I would like script something on a daily or weekly basis.
Thanks,

RMAN not easy? Lets see how hard it is:
rman target /
RMAN> backup database;Surely that isn't too challenging.
Now if you want to do it properly you are talking about setting up a repository ... much more complex:
-- on the repository database server
CREATE USER repos
IDENTIFIED BY oracl1
DEFAULT TABLESPACE users
TEMPORARY TABLESPACE temp
QUOTA UNLIMITED on users;
GRANT create session, recovery_catalog_owner TO repos;
-- on the target server (your production db)
rman target / catalog repos/oracle1@<tnsnames_entry_for_your repository>
RMAN> create catalog;
RMAN> register database;
RMAN> backup database;If this is too much perhaps you should look into MS Access. <g>
All of this is documented at the top of the RMAN page in Morgan's Library at www.psoug.org so you can cut-and-paste your way through it if you want.
How is an export not a backup you ask?
The Oracle docs can be found at http://tahiti.oracle.com. You should consider reading them some time.
As I said before ... an export can NOT be used to recover ... ever. That says it all.
Your resistance to change. Your resistance to doing things properly. Your resistance to reading the docs. You'd better watch out. There are people who would like to have your job ... a lot of them.

Backup and Recovery from Archive Log

Dear all,
I implemented hot backup with oracle9i and
Can anybody suggest me how to backup and recovery archive log ?
Thanks for advance.
Chara

assuming you are using RMAN for backup -
backup ( archivelog all );
backup ( archivelog all delete input ); - to delete from file system.
If you are not using RMAN but backup using a script which puts the tablespaces in hot backup mode then you just need to backup archive log directory.
The archive logs are required when you need to do a database recovery. You don't recover archive log files.

I am trying to use a website that requires that my computer have the latest version of Java, which I have updated and installed Java 7 Update 51 (64-bit), however Firefox does not recognize that I even have Java on my computer. My computer is 64-bit
When I run "Verify Java Version" it show nothing is installed... but it is, I know that for a fact because it shows in my "Control Panel/Programs/Programs and Features".
When I go back to the Java Download page, the following message is visible:
"We have detected you may be viewing this page in a 32-bit browser. If you use 32-bit and 64-bit browsers interchangeably, you will need to install both 32-bit and 64-bit Java in order to have the Java plug-in for both browsers."
My question is this:
Is there a way to change my Firefox browser from 32-bit to 64-bit.... because it appears that this is way Java is not functioning properly?

Firefox needs 32-bit plugins, so you'll need to install 32-bit Java for Firefox.
No, you can't change Firefox from 32-bt to 64-bit. There is a Nightly 64-bit version (alpha) of Firefox, but it is used only to test for regressions until development is resumed.

I have just updated to Pages 5.1 and now the templares which I have saved do not displat the header and footer which they were saved with in the previous version. How can I have the header and footer included when I open a template?

I have just updated to Pages 5.1 and now the templares which I have saved do not displat the header and footer which they were saved with in the previous version. How can I have the header and footer included when I open a template?

That is becuase Pages 5.1 has numerous unnounced surprises for the unwary user. Among the surprises:
- it strips out images from headers and footers without warning
- it strips out bookmarks without wanring (yes, all those bookamrks you laboriously put into a document: poof! Gone.)
- it strips out alternating left/right margins, without warning.
There are many more suprises, as you'll see from glancing through these discussions. They fall into two main categories: things that are present in version 4.3 but that are missing in 5.1, things like
-mail merge
-meaningful Applescript/Services support
-non-contiguous text selection
-ability to set defaul zoom
-ability to see comments while editing
-ability to print comments
-ability to read RTF files
-ability to drag in hyperlinked ted from a browser
These about about 90 other features are gone.
Then there are the bugs. Hyperlinks do not reliably export to a PDF file any longer. There have been multiple problems with printing report. Some fonts place stray characters in the headers. Many reports of the program crashing, courrupting files, etc.
Fortunately for you, the previous version of Pages is still on your system. Export any documents you may have created or edited with Pages 5.1 (another great surprise: files created with version 5.1 cannot be read by any previous version of Pages: not just 4.3 but even 5.01!). Then trash 5.1 and use 4.3 until (unless?) it is stable and has a reasonably robust feature set.

James Ward4 Thanks for your suggestion. I have tried the video app and it appears to have some, but not all of the downloads which are viewable without wifi, so I will now review the download process and see if I can capture the missing episodes. Thanks again.

I assume you mean the phone is asking for the 4 digit password you set at the time of the backup of the phone...

I have just bought an iPhone 5 and it won't sync to iTunes. It says it needs iTunes 10.7, which I have downloaded and installed. I still get the error message and looking at "about iTunes" it says 10.6.3. What do I do??

Perhaps check to see if you're accidentally running two different versions of iTunes. There's some information on troubleshooting that in the Opening iTunes section of the following document:

I have an iPad1 which I have reset and am preparing to give to a kid. I now find that I can't reinstall many apps as they now seem to require IOS 6 or greater. This is IOS 5 and can't be upgraded. Is there a way to find the older versions of the apps?

One of these links may help:
iOSSearch - search the iTunes store for compatible apps.
Vintapps 3.1.3 - paid app.

If you were given an ID and password by your IT department, it's their problem. If you created one yourself, you can retrieve it at https://iforgot.apple.com/appleid.
There's nothing anyone else can do about it.
If your IT department handed it to you without clearing the iCloud account that was already set up on the phone before doing so, and you didn't even try to turn it on, just plugged it in and restored it, which updated it to iOS 7, then it's activation locked using the account that was already on it. If it's company owned, they will have to take the phone and proof of ownership to Apple to have it reset.

When you buy software to download it's VITAL to archive what you download, preferably to a CD/DVD. I write the serial number on the disk for completeness.
That said, you may be able to log on to My Adobe and see if they have a record of your purchase, and it's recent enough to still have a download. If it's the CURRENT version you can just download the demo.
