Hi Team,
I need some real time stuff how does at Enterprise level one backup and restore archived log files?
What kind strategies do they follow.
I want know more on this topic. Can anyone please help me out.
Please dont say that we take the backup's of archives on tapes and CD's. What i want to know is that how exactly the Database Adminstrator's
restore the backup of the archives generated and how many sets of Archived log file Backups are generally maintained in the Production Environment.
I just want to know various strategies that would be implemented especially on Archive log files are concerned.
Best Regards
frank

Here is what I do.
Each night the operators run a job. We have 5 versions, that is 5 nights of backups at any time. By changing the directory name we move directory 4 to directory 5, directory 3 to directory 4 and so on. Then we build a list of all table spaces in plsql, excluding temporary tablespaces. The job puts the tablespaces, one by one, into and out of backup mode and copies the tablespace to directory 1. Then we switch logfiles and include it in the directory 1, which is our 'destination directory' and backup the controlfile and logfiles as well. Then we compress all the files.
I have all the code for you if you wish. This code is for any unix running any version of Oracle. Let me know if you need the code.
The operator needs to be sure the backup completes because you do not want to leave a tablespace in backup mode any longer that necessary.
Restore is a little tricker. It requires Knowlege of tablespace and archivelog locations. You NEVER want to restore a controlfile unless it is your only option. The controlfile does not know anything that happened after the backup so you lose data.
We run live backups usually after the batch jobs run.
Another option is the export/import mode. I do not use it because of the limitations.
I am glad I have only had to restore 2 times in the last 10 years. Both times we because of a 'user' error. You have to do a 'point in time' recovery.
Good luck and let me know if you need the shell scripts for the backup.
Neil.

Here is a start.
We use hotbackups via scripts, and version them to have 5 sets.
Don't copy the control file or you will lose everything done after the control file was taking.
Here is how we do it.
>cat hotbackup_start.ksh
#!/bin/ksh
#@(#)hotbackup_start -- starts S2000 hotbackup
###
# Korn script to start hot backup of the S2000 database
#
# Autor: Neil MacDannald
# Date: 8/10/2005
###
#
# Inform operator what job they have requested
# Ask if they wish to continue
#
echo " "
echo "*****"
echo Starting hot backup of S2000 database
echo "Continue? (Y/N)"
read answer
echo " "
if [[ "$answer" = [Yy]* ]]
then
df -k /u26
echo `date`
thedir=`pwd`
echo " "
echo Enter password for S2000 ORADBA
sttyops=`stty -g`
stty -echo
echo "Password: "
read password
echo " "
stty $sttyops
#
# Start the hot backup job
#
sqlplus ORADBA/$password << EOF
@$thedir/hotbackup_start
exit
EOF
sleep 20
`cp /u01/oradata/os2p/ctl/*.ctl /u05/oradata/os2p/budir`
`cp /u01/oradata/os2p/ts/*.log /u05/oradata/os2p/budir/`
df -k
echo `date`
fi
which calls:

Hi,
In the place iam working they want weekly,monthly and yearly backups of the whole data in such a way that after taking the backup of the whole year we want the whole old data to be removed from that system and be backedup to elsewhere but should be able to retrieve the data whenever required.
Thanks.
