Backup the database without shuting down the database

Hello All,
Just want to ask if any one can tell me if it is possible to backup the database without shutting it down
When can you do so if it is possible?

A hot (or on-line) backup is a backup performed while the database is open and available for use (read and write activity). Except for Oracle exports, one can only do on-line backups when the database is ARCHIVELOG mode.

Shutdown CRS without shuting down database?

hi forum
It's all know that if I shutdown the CRS, the CRS daemon will shutdown the database as part of it shutdown procedure.
How can I shutdown the CRS without shuting down the database ?
Thank you for your time.

hi all
I have found the solution:
follow steps below:
1) use crs_stop to stop the database resource
2) use srvctl remove to remove the database
3) startup the database
Now the database is not under control of the CRS.
You can later use srvctl add database back to the CRS if you want the CRS manages the database for you.
Thanks for your time.

Following the latest upgrade how to exit Firefox without shuting down

Computer type: Mac BookPro Mac OS X Version 10.6.8
I use both the Mac Safari & Firefox browsers for blogging. Since yesterday when I downloaded the Mozilla Firefox upgrade I am unable to exit Firefox at all (no button or tab to select an exit to return to desktop and Safire). To exit Firefox I must press the manual quit button to restart the computer. I need a Firefox exit link out to reenter the Safire browser and desktop without shutting down the computer.

You should see the Firefox menu bar on Mac as that is controlled by the Mac OS and have Firefox > Quit.
Try to remove the Firefox plist file (org.mozilla.firefox.plist).

What is your reason? RMAN=hotbackup means you dont need to shutdown db or apps. For our client we never close appstier while we are taking RMAN backup

Is it possible to reload Handler files without shuting down OC4J

Is it possible to reload the Handler files in OC4J ?
When a new Handler file is generated by the JAG I need to restart OC4J otherwise I get a Handler not found exception.

Handlers are java-classes so I would say yes.
Classes (including BC4J View and Entity objects) must
be recompiled and your server should be restarted.
Anything XML-related (including UIX) does not immediately
force you to restart OC4J, although the MVC Framework
descriptor-xml should be reloaded by for instance re-
entering the service you changed. This is where those
home-page services become handy.
Note that setting existing BC4J-attributes to (in)visible
or wider/smaller mostly just changes the BC4J Jheadstart
metadata and generates new UIX, so it doesn't change
anything in the java-classes.

DAG - Backup failing on 1 DB only with error - The Microsoft Exchange Replication service VSS Writer instance ID failed with error code 80070020 when preparing for a backup of database 'DB012'

Hi Board,
i´ve search across the board, technet and symantec sites but did not found a hint about my problem.
we drive a 2 node DAG (Location1-Ex1-mb1
Location2-exc1-mb1), on SP2 RU4 patchlevel with 40 Databases.
Since some time the backup of one - and only one DB - is failing with these events, logged on the Mailboxserver on which the passive DB is hosted.

Symatec suggests within http://www.symantec.com/business/support/index?page=content&id=TECH184095
to restart the MS Exchange Replication Service – BUT the mentioned eventID
8229 isn´t present on any of the both Mailboxservers.
The affected Database is active on Location2-Exc1-Mb1 Server and in an overall healthy state. I found during my research, that below Location2-Exc1-Mb1 Server, there are not removed shadow copies present!
This confuses me, since all Backups are normally taken from the passive copy of a Database.
So my questions to the board are:
* Does anyone is facing similar issues?
* Can someone explain why snapshots are present on the Mailboxserver hosting the Active Database, whilst the errors are logged on the passive one?
-          * Does someone know the conditions, why shadows copies remain and
aren´t removed in a proper manner?
What can cause the circumstance, that only 1 DB is facing such issues?
Any suggestion is welcome!

Hi Lenora,
I´ve encreases VSS / Exchange Backup Log levels to expert, before starting
those things i´ve all tried now:
- Backup from passive DB (forced within Symantec Backup Exec)
- Backup from active DB (forced within Symantec Backup Exec)
- Backup from passive DB without GRT enabled (forced within Symantec Backup Exec)
- Backup from active DB without GRT enabled(forced within Symantec Backup Exec)
All those attempts failed.
But brought some more details - the backup against the active DB states, that there is still a backup in progress and therefore this backup is cancelled by VSS.
The Solution was, that i´ve needed to restart the Exchange Replication Service on the Mailbox Server hosting the passive DB.
Backups are working again on all DBs!
THX for your replys.
Best regards
Markus

Cloning without shutting down the db

Hi,
Can you please suggest how to clone apps and db without shutting down the database? Apps is just copying the files, is there a recommended way to do the db cloning without shutting down the db.

SAP System copy without shutting down the source and the target system

Hi,
We need to need to System refresh without shutting down both the source and the target system, i read the docs from SAP looks like we need to shutdown the source system during export and import phase, is there any way to do the system refresh without shutting down the system.
Sathish

Hi,
Think a little bit about what is a database and you'll get the answer that what you "need to need" is impossible.
Of course it is possible to keep the source running (hopefully, because ususally it is the production system !) by using an online backup, but you need to stop the target system because you will restore a backup on it.
If you use the export/import way, you have to stop both source and target system.

How to upload files in cluster without bringing down the cluster.

Hi,
Here is my problem:
My weblogic portal 7.0 application should run in 24x7 environment. The production
system is running in a cluster mode with external staging. Both the managed servers
are pointing to the same application sync database.
So to give a solution to this problem, we are trying to bring down one managed
server down and apply the patches into that managed server without bringing down
the other. Since webflow files and entitlements needs to be synchronized with
the portal database. If we perform a sync on the portal database, there might
be a chance that it might corrupt the existing portal database state. Our deployment
would not be complete unless we perform a sync on the other managed servers. So
we could not able to update the latest pathces into the cluster without bringing
down the cluster.
What I would like to know is "Is there any work around to get rid of this problem?".
I would be delighted if any one provides the solution.
Thanks & Regards,
Ratnakar

Hi Ratnakar,
When you perform sync you do it against the admin server which in turn does it
to the managed server. If you want to apply any changes to webflow you can do
it on the live system itself. I mean apply the new webflow and entitlements and
do the sync on the live system. Also while doing sync there are two modes. One
mode will sync only the modified changes and the other will apply all of it. You
can opt for the first option by which you can sync only the modified changes.
This may bring a small disturbance but it will be unnoticed.
The other option is to have two separate domains(each having one admin & one or
more managed servers) which may be having two separate portal databases. In this
way you can apply patches to one domain while other domain may provide the service.

Can we put RAC database in Archivelog mode without shutting down

All,
Can we put RAC database in Archivelog mode without shutting down.
Currently our new production database (2 node RAC) is in no archive log mode, Need to enable archive log in the database...
I believe we need to set the cluster_database=false and then put the DB in archive log mode then we need to bounce the database to take effect...
Just curious to know in 11gR2 ...Can we put the RAC database in archive log mode without any downtime ...?

Even RAC or non-RAC, database should bounced and enable/disable archive log mode from mount status.

Is it possible to backup my iPhone without getting into the phone?

I have a white iPhone 5c 16GB. It's my second time owning one, and the current one I have is from Asurion insurance company. I have heard those have been refurbished, so when I received my current phone I felt like it had already been old. iPhones don't have long life spans, for one. I would drop it a couple times and the edge of the screen would pop out but i would just push it back in using some force. Another problem it had is that it would die even when it had about 30% of battery left. Earlier today, it did the same. Trying to get my charger, the phone accidentally fell off of the bed while it was dead. As usual i check for cracks or the screen popping out and that didn't happen. I charged it and when i tried going on my phone I was only able to use half of the screen. The other half was covered in those lines that appear when the screen is damaged. My immediate reaction was to plug it into my laptop to backup the phone before more damage happened to the phone but I had procrastinated on updating itunes. It took about two hours for iTunes to completely download. Meanwhile the screen had just completely failed on me showing only the colorful lines, but i was still receiving calls and the phone could still vibrate, i just couldn't see or check anything at all. Once i was going to back it up, itunes said my phone was in recovery mode and that i had to restore my phone. I have precious photos that i want to keep when i get a new phone. Is it possible to backup the phone without using itunes and just using icloud? its saying my phone is connected yet im unable to see any proof of that other than the sound my laptop makes when i plug it back in. Also, if that doesn't work or is not possible, will i be able to just stick my sim card into a new phone and will i be able to keep my data?

That's what I figured. When i go on icloud it shows the bar of the storage, and since i havent purchased extra, i only have the free 5gb. in icloud the bar shows the amount ive used and it says "backup" on the bar. It's not a link it's just a label. Does that mean it's backed up automatically on icloud?

Is there a way to backup the iphone without entering a passcode that was previously set?

I have a passcode on my iphone, which I recently dropped. Both the front and back screens are cracked severely. I can see when someone txts / calls, so the phone appears to be working, however it is not usable. I cannot access anything on the phone using the touch screen. The screen continues to shake as if there are multiple fingers trying to operate it at once.
Although it would be nice to get back into the phone, I would prefer being able to back it up just one more time. I sync frequently to icloud, but the last time I backed it up to my pc was 11/16/2011. I can access everything I've backed up(txts, images, etc via other applications), but I have some important correspendeces that took place between then and now that I would like to have.
Is there way for me to backup the phone without entering the passcode? Also, I have read through some of the discussions, and pardon my ignorance but I wanted an unequivocal answer to this question: If I restore the phone from the backup of 11/16, will I lose everything after that date? And, are there other alternatives?
I have tried some things which I thought would be clever ways to bypass this problem, but alas...here I am asking for help. I find it frustrating that I can sync to icloud (still) yet I cannot backup to my pc without passcode. I guess a good alternative would be if I could access my txts on icloud? I may consider replacing the screen, but I don't know if this will fix the problem since the phone looks pretty bad. I also prefer not to replace the screen since I wont be using this phone any longer.
Your comments / suggestions will be greatly appreciated.
Thanks,
reaL

Restoring a phone from a backup will put the device back to the state it was when the backup took place, i.e. all info that you had on that phone before using the backup will be gone.
You could try to restore the phone, which will back up the actual data on the phone, including the passcode, and use this backup to set up a new phone with. The passcode will still be the same, because it is part of the backup.
More info here, iPhone and iPod touch: Wrong passcode results in red disabled screen
Not being able to fill in the passcode is not much different from forgetting it.
If you cannot remember the passcode, you will need to restore your device using the computer with which you last synced it. This allows you to reset your passcode and resync the data from the device (or restore from a backup). If you restore on a different computer that was never synced with the device, you will be able to unlock the device for use and remove the passcode, but your data will not be present. Refer to Updating and restoring iPhone, iPad and iPod touch software.

How do i backup the list of load images automatically exceptions under Options- Content. I want to transfer to another comp without re-adding one at a time

How do i backup the list of load images automatically exceptions under Options->Content. I want to transfer to another comp without re-adding one at a time. EVen if there is no way to backup, what is the system file for Firefox that stores these, so i can transfer this file or open it in an XML or similar editor to copy them out?

The permissions.sqlite file stores 'allow' and 'block' exceptions for cookies, images, pop-up windows, and extensions (software) installation.

What's happening on my iMac? There are two choices of selected start up disks appearance without hold down option key. On the other hand, it start up normally show apple picture when I hold option key.

There are two choices of selected start up disks:Main HD and Recovery HD, appearance without hold down option key. On the other hand, it start up normally show apple picture when I hold option key.

Hi artdiva28
Welcome to Apple Discussions
First go to *System Preferences > Startup Disk* > select the *Mac OS X 10.5. on Macintosh HD* > click the Lock > hit the Restart button.
Then if the iMac is still having trouble starting up, insert your Install Disk and restart holding the Option key. In Startup Manager select the Install Disk and boot into it, choose your language, skip the Installer and go up on the menu bar to Utilities and open Disk Utility. In Disk Utility select your Macintosh HD and hit the Repair button. Once finished note any errors and what was repaired for future reference. Quit Disk Utility and restart once again holding the Option key boot back into the Macintosh HD and eject the Install Disk.
