OFFLINE BACK & ONLINE BACKUP

I want to take a offline backup as well as online backup also.
Operating System is Windows NT 4.0.
Oracle version 8.0.6.1.0
what are the preventive steps should i follow and what are the commands to be use to complete this task.

You are using ANCIENT software! Neither NT 4.0 nor Oracle 8.0.x is any more supported...

Whether to take Offline (or) Online backup

Hi
      I am planning to apply support pack 14 now I am in SP13 before applying SP14 I am planning to take Database backup.
      What is recommended whether to take Offline or Online backup,
      Can any one explain which the best way to take backup is.

Hi,
Taking a successful backup is must(suggested) before Support pack implementation.
However online/offiline anything will be ok.
As online backup is taken to minimise the downtime for SAP application.
If you can get a downtime you can go for offline backup..
Say if you can not get downtime then go for online backup.Given you are running in archive log mode.During this performance will be little degraded.that is why suggested to run online backup in off -peak hours
You can go for a online backup before night(starting of SP implementation) and before starting the support packs do a log switch and then do a archive backup and make a note of that log number and start the SP implementation.
In case of problems when you have to restore the backup restore the backup and recover until the log number which we generated just before the SP implementation...
Thanks.

Offline or Online Backup after switching off and on the archving mode

Hello guys,
I am doing an SAP (on Oracle) upgrade. In the upgrade guide there are two completely different statements about making a backup of the Oracle database during upgrade.
1st statement:
"If you deactivate archiving, you have to make a full backup of the database after the downtime before you switch archiving back on. This must be executed as an offline backup."
2nd statement:
"Backup: Database Was Operated in NOARCHIVELOG Mode
Activate ARCHIVELOG mode again and create a full backup of the database. This must be executed as an offline backup."
Quotes from: "Upgrade GuideSAP ERP 6.0 Including Enhancement Package 4 Support Release 1 ABAPBased on SAP NetWeaver 7.0 Including Enhancement Package"
I understand the fact that the backup has to be offline if you do it before you activate archiving. This is logical.
1) Why does SAP do these two proposals before and after switching on archiving which are completely contrary?
2) Why does the backup has to be offline if you do it after switching on archiving?
May be somebody knows the background for this.
Thanks
Nik

Hi,
Two kind of Recovery play an important role in Database Recovery after DB Restore. The Database recovery can be Compete recovery, point-in-time recovery or partial recovery.
Media Recovery (due to media failure/corruption or loss of Data files) can be performed by applying all Offline Redo Log files which are generated from Online Redo-log file in Archive Mode.
Instance Recovery can be done with the help of Online Redo log file and undo table-space to achieve consistent status of Database. In this recovery the committed transactions (which are logged in Online Redo Log files) are roll forward and the uncomplete transactions (which are also logged in Online Redo Log Files) are rolled back into DB using Undo space info.
If you deactivate archiving, you have to make a full backup of the database after
the downtime before you switch archiving back on. This must be executed as an offline backup.
                   With Archive log Mode , one can deal with Media Recovery and Instance Recovery. Upon deactivating Archive log mode, the Archive log files will not be generated and the circular logging will take place within the group of online redo log files.
                   So, after deactivating Archive Log mode, Its recommended to take immediate offline backup to have consistent Backup copy of Database which may be required to deal with demanded media recovery by restoring that immediate latest offline Backup. If the database operates in NOARCHIVELOG mode, the database can ONLY be completely recovered from instance failure but not from media failure. This means that, in case of media failure you will lose all work done after the last valid offline backup. The database can be backed up only while it is completely closed.
                   Upon media failure after deactivating the Archive log mode (..rare chance, but we can not ignore it...),the complete recovery can not be achieved if the large time gape is there between the last successful offline backup and DB crash because between this time it may be the chance that the Online Redo log files are overwritten so many times in circular manner.

Ubuntu 2014 LTS - (offline vs. online) Backup questions

Hey guys,
I have a brand new Ubuntu LTS machine and can back it up properly.
But I don't understand why the machine is offline within DPM.
What I have is a small test System of Ubuntu Server 04.2014 LTS and i installed the
VSS Snapshot daemon –
"This daemon is required to create live Linux virtual machine backups."
and KVP daemon as well.
Following the TechNet entry:
http://technet.microsoft.com/en-us/library/dn531029.aspx
Live virtual machine backup
2012 R2
√ Note 3, 4, 5
So I'm not sure where the Problem is. Shouldn't the machine visible as online due to creation a protection Group of DPM?
Everytime I'm creating a recovery Point and run a backup the machine is still online and I couldn't see an offline behavior which i would expect (save state).
May I understand something wrong? Is there a backup guy here who has more Expertise with Debian and or ubuntu machines and can give me a hint?
P.S.
guest Services are enabled and the usual stuff like rebooting and dynamic Memory seems to be working very well.
I have also an VMM 2012 R2 running but I'm pretty sure there shouldn't be a problem?!

Hi,
<snip>
Everytime I'm creating a recovery Point and run a backup the machine is still online and I couldn't see an offline behavior which i would expect (save state).
>snip<
At the time of adding the VM to protection, DPM queries the hyper-V writer on the Hyper-V host to get a list of guests and their backup state (caption). At the time, that state reported (offline) so that is what was used in DPM UI. If the machine
later can be backed up in (online) state, then it will be backed up online, but the DPM UI is still going to show (offline). To make the DPM UI show online, you need to stop protection, retain the replica, then reprotect. At that time hyper-V writer
will report (online) and DPM UI will reflect going forward.
To list hyper-V writer captions for guests to see if online or offline state backups will be done:
From an administrative command prompt on the Hyper-V server:
a. Type: copy con script.txt and press enter
b. Type: list writers and press enter
c. Press CTRL + Z + enter (to save)
d. Type: diskshadow /s script.txt | find /i "caption: O"
Output will be displayed for each guest as follows.
C:\temp>diskshadow /s script.txt | find /i "caption: O"
 - Caption: Online\SCS2012R2-DC
 - Caption: Online\SQLSERVER
 - Caption: Offline\MJLC-WSS-V14
 - Caption: Offline\MJLC-DPM2012Sp1

How to confiuge RMAN offline and online back-up at a pre-determined time.

Hallo!I am an Oracle newbie currently studying the Oracle 10g Database Administration Certification.Still very new to Enterprise Manager.
My query is that can you configure an offline database back-up such that you can set up an offline backup at a pre-determined time?
I am assumng a real-office scenario where a DBA would like to have an offline back-up at night e.g. at 1 am when they are no users in the office.If the DBA can set the system such that everday at 1 am ,the instance shuts down,back-up is done e.g a backup set that can be stored on tape,then after backup the instance re-starts itself.All this should be automated such that by the time staff report in the morning ,the instance is up and running and users can work seamlessely
How can I automate this entire process using RMAN and/or Enterprise Manager or a sript to achieve this?Also,I would like to know if you can automate the same for online back-up such that it can backup while instance is still running and users are accessing the DB.
Please help me on this and I shall be infinitely grateful.Thanks in advance.

Hi,
On UNIX server, you can use shell script and sql scripts that can do this job for you. Once the scripts are tested succesfully, you can put them in the crontab.
Crontab entry should reflect the time, day, week, month details as you thought to schedule it.
This link may help you. http://www.dbasupport.com/oracle/scripts/Backup_Recovery/RMAN_Backup/

Offline and online back up

what is the offline back up and online back up,

hi s reddy,
in general words,complete backup is called offline backup which needs to schedule downtime and complete backup is taken.
online backup is nothing but daily backup when the system is up and running and no system downtime is required.

Offline & online backups????

Hi all,
Why are the advantages & disadvantages of offline & online backups??

Hi Ravi,
Joydeep has described it very well.
Just to add a bit:
If you are wondering what happens to the online redo log files while the online backup is running:
During online backup, BRBACKUP does not backup the online redo log files. Instead, BRBACKUP generates online redo log switches so that all the online redo log files written during the online backup are copied into the archive directory. These offline redo log files then need to be backed up, since an online backup is consistent only in conjunction with these redo log files. The BRARCHIVE program backs up the offline redo log files.
So the idea that during an online backup some redo files might be missed, is explained from the above paragraph.
Regards,
Loukas

When I open Mail, all accounts are offline. It takes time to get them back online. This is an on-going problem that has been chronic and it has finally gotten me "inspired" to ask the Community

When I open Mail, all accounts appear offline. I have to get back "online" before mail is delivered or sent. Hassle. Any Ideas??

I was having this same issue all week. I'm also using 10.8.5 It was driving me crazy. I think I found a solution. I downloaded and installed the latest security update from Apple in the App Store. I have not had a reoccurance since (?). Maybe that will help you as well.

I updated my iMac, and my mail no longer works. It says all of my accounts are "offline". Safari is fine. How do I get my accounts back online?

I updated my iMac and now my Mail does not work. It says all of my accounts are"offline". Safari is fine. How do I get my accounts back online?

Hello there, Lynn.
The following Knowledge Base article explains and offers up some troubleshooting recommendations for issues with email acounts showing offline on Mac Mail:
Mail (Mavericks): If a mailbox is offline
http://support.apple.com/kb/PH14925
Lightning bolt icons next to mailboxes in the Mail sidebar identify accounts that are offline.
To take an account online, click the lightning bolt icon. Or choose Mailbox > Online Status > Take [account name] Online, or Mailbox > Take All Accounts Online.
If you can’t take an account online, make sure you’re connected to the Internet. If a warning icon appears after the account name, click it for more information.
Use Connection Doctor
Some mailbox names can appear dimmed if you don’t have permission to access them, such as “public” mailboxes on a server, or if the mail server is unavailable.
Thanks for reaching out to Apple Support Communities.
Cheers,
Pedro.

TS2774 on my iphone, in Safari(not limited to) I get the message unable to connect to server,now the message says the internet is offline, how do I get it back online?

On my Iphone4 3G, which I have upgraded to 6.0, and, have had many issues but this is my main concern: Everytime I go to Safari (or dif. sites) I get msge that reads "cannot connect to server", today it upgraded to "that msge plus this "the internet is offline". How do I get it back online?

Wi-Fi, Cellular Data, or both?
Do you actually pay for a data plan from your carrier?
Are you in an area with a Wi-Fi hot spot to connect to?

TS1307 my "outgoing Mail server is offline and I can't get it back online

I can send and receive emails from my iphone, ipad and online mac account, but can not send emails on my mail from my macbook, it stopped working suddenly a few weeks ago and says all my outgoing smtp's are offline, how do i get them back online?

Thanks so much for the quick response.
I did repair permissions and tried Mail again, then decided to double check the Mail Prefs of my MB Pro (where Mail works fine) and the iMac (G5 I think?). And do I feel stupid: the outgoing mail server on the iMac was smtp.mac.com whereas the server on the MB Pro was smtp.me.com! So I changed that and now Mail can be sent from the iMac.
Thanks so much, I love these forums. Whenever I have a problem, I check the forums first!
Cheers,
Laurie

N96 offline - can't get it back online!

Hi all - my N96 (had it about 2 months) keeps doing some annoying things:
-randomly it will come up Insert Sim and require restarting
-it will turn itself off
and the killer one
-when I restart it, it comes up frequently in Offline Mode.
Sometimes I can restart it again and get an option to continue Offline or Online, so I can select Online and use it again as normal. There is not always this prompt...this time, it's Offline and staying that way. I have restarted about 10 times now and I can't get it to come Online again. Is there an option somewhere in the phone that I can't find?
I updated the firmware when I first got it but find the thing ridiculously slow, who should wait minutes to open a text message? Am seriously tempted to take it back in case it's a dud - or are these common problems?
When I wanted the phone at my upgrade, the person dealing with my upgrade warned me off the phone saying they were almost 100% faulty...but reading here, some people seem to not have the problems that I do!
Thanks in advance for your help re: my various questions!

Not all N96 behave like this-certainly mine does not. However, there might be something wrong with your SIM card. I had an similar issue in a previous phone and it turned out to be the SIM card-it does not recognise it and it goes offilne. Other than that, try to change the settings so you can save sms to phone memory not mass memory- this helped some people..

No Online backups due to datafiles offline than I canu0092t recover. How...?

Hi gurus!!!
I got into a problem with some datafiles.
We have MySAP in a BD oracle 9.2.0.6
I used Oracle Entreprise Manager Console to generate two datafiles in the tablespace PSAPPRDUSR,
but I generated them in another tablesapce (PSAPPRD) with a name of file,
size and location very different from those that there uses the tablespace PSAPPRD.
So... I put them offline later to erase them later!!!
The datafiles contains no data.
Later, in the night backup:
 BR0334W Status of database file /oracle/PRD/sapdata4/prdusr_2/prdusr.data2 is RECOVER
 BR0334W Status of database file /oracle/PRD/sapdata4/prdusr_2/prdusr.data2a is RECOVER
 BR0301E SQL error -1128 at location BrTspAlter-3
 ORA-01128: cannot start online backup - file 31 is offline
 ORA-01110: data file 31: '/oracle/PRD/sapdata4/prdusr_2/prdusr.data2'
 BR0280I BRBACKUP time stamp: 2007-04-20 03.01.21
 BR0316E 'Alter tablespace PSAPPRD begin backup' failed
 BR0056I End of database backup: bdvbtndh.ant 2007-04-20 03.01.21

And now... I neither can erase them nor can put online again.
To erase them I used:
SQL> ALTER DATABASE DATAFILE '/oracle/PRD/sapdata4/prdusr_2/prdusr.data2' OFFLINE DROP;
Database altered.
SQL> commit;
But they continue there, do not resign.
To put them online:
SQL> alter database recover datafile '/oracle/PRD/sapdata4/prdusr_2/prdusr.data2';
alter database recover datafile '/oracle/PRD/sapdata4/prdusr_2/prdusr.data2'
ERROR at line 1:
ORA-00279: change 31203204 generated at 04/19/2007 19:30:11 needed for thread 1
ORA-00289: suggestion : /oracle/PRD/oraarch/PRDarch1_2574.dbf
ORA-00280: change 31203204 for thread 1 is in sequence #2574
SQL>
But we have continued working and I don't want to lose any data.
HEEEELP!!!!
What I can do to recover the datafiles and to continue with my daily Online backups?
The BD is in production and I do not have long time to fix it, only a few hours on Saturdays night.

Hi,
alter database datafile offline drop;
This command is not meant to drop a datafile. It is meant to offline the datafile with the intention of dropping the tablespace.
For a tablespace comprising multiple datafiles you can only drop a datafile by dropping the entire tablespace, this will work even you have one datafile.
If you have 10gr2, it's finally possible to drop a datafile as long as
it's not the only datafile within the tablespace, and
the tablespace is only and in read-write status.
So since you are on 9i your situation in summary:
If you have more than one datafile in the tablespace and you wish to keep the objects that reside in the other datafile(s) which are part of this tablespace, then you must export all the objects inside the tablespace.
1. Gather information on the current datafiles within the tablespace by running some query to remember the t/s, segment, and datafile info.
2. Export all the objects that you wish to keep.
3. Once the export is done, issue the DROP TABLESPACE <tablespace name> INCLUDING CONTENTS.
4. Delete the datafiles belonging to this tablespace using the operating system.
5. Recreate the tablespace with the datafile(s) desired, then import the objects into that tablespace.
Hope this helps and good luck,
George

STILL need to go Offline and back Online to obtain mail

OK, several weeks later, and I have (1) used the OS X utility programs to check permissions, etc; (2) rebuilt my mailboxes; (3) deleted most stored e-mails; (5) run software update; and (?) tried other things that don't come to mind right this second, but STILL, my Mail frequently needs to be taken Offline, and then back Online for messages to appear. Lots of my mail comes from AOL accounts, but some from Apple Mail, and both suffer from this problem.
Can anyone suggest something else I can try to get e-mails automatically and consistently?
Steven

When you say "minimum," do you mean NOT 1 minute? Recently, I changed it to 5 minutes from one, without resolving the problem.
The problem I am trying to describe/diagnose was discussed several weeks ago. I should send myself some non-AOL mails to make sure the problem is not AOL specific (most of my discussion group e-mails come via an aol account)...
Would changing the pop port and/or imap port affect this issue?

I was connecting on my ipad to Find my ipad with the account of my sister (somebody stole her ipad..) and her ipad was obviously offline. Then i removed her device from the list (i know itd reappear on the list if it comes back online),but can i readd it?

Question above

i didnt mean to remove it, i did it unintentionally.
If the offline device is removed do i receive emails if it comes back online?
p.s.: still no answers to how i have to put the offline device back on the list of my devices?!?
