Hot backups in Oracle 10g R2

Hi
How to take up Hot backups (On-line backup) in Oracle 10g Release 2 in Windows environment.
Pls give me the link or steps for do the hot back-ups.
Thanks

I think you are test ENV?
Did you archive the current log file which i mentioned in the earlier post
if so and if you the archived log
Shutdown the DB
Rename the file you copied
move the D:\oradata\*.dbf(whihc was backed up by you)in the original directory and
from sqlplus issue
SQL>startup mount
SQL>recover database
this hould work
But make sure you have the backup before deleting/renaming the the file you backed up by HOTbackup

How to take a Hot backup of Oracle database

1: put the db in archive log mode
2: set the db_sid to correct one
3: login to sqlplus
4: verify the name of the db that you are connected to
select name from v$database;
5: check if the db is in archive log made
select log_mode from v$database;
if not in archive log mode
another command to check
archive log list;
6: find where on disk oracle writes archive log when it is in archive log mode
sql> show parameter log_archive_dest_1;
if the value is found to be 0, that means no values will be recorded, so we need to change it
sql> alter system set log_archive_dest_1='LOCATION=c:\database\oradata\finance\archived_logs\'
scope=spfile;
7: shutdown immediate; < this is done just to prepare the db for hot backups >
8: startup the db in mount mode
startup mount;
( 3 startup types : nomount - just starts the instance, mount - locates the control files and open up according to the values, open - finds the datafiles from the control files and opens up the db )
9: put the db in archive log mode
alter database archivelog;
10: open the database
alter database open;
11: check the status of the db
select log_mode from v$database;
SQL> archive log list;
12: create a directory for archived log
check if its empty, if empty we need to switch
sql> alter system archive log current;
run it 5 times < need to put / and enter > , then check the archive log dir , we will find files
13: make a table in the database and insert data in it
create table employees (fname varchar(2));
check the table
desc employees;
insert values
insert into employees values ('Mica');
14: tablespace must be in hot backup mode
check the status
select * from v$backup;
if found not active, then we need to change
we cannot put the db in hot backup mode, unless it is archive log mode
change to hot backup mode
alter database begin backup;
check the status
select * from v$backup;
15: now we can only COPY DBF FILES
copy *dbf <distination location>
16: need to take the db out to hot backup mode
alter database end backup;
17: need to make another archive log switch
alter system archive log current;
18: need to copy control files now, need to do a binary bckup
alter database backup controlfile to '<location>\controlbackup';
19: insert more values to the table
insert into employess values ('NASH')
COMMIT;
make another archive log switch : alter system archive log current;
do the same process for more values
20 : backup all the archive logs to a new location
21: shutdown the db and simulate a hw error, delete all the files from the database folder
22: try to start the sqlplus and db ::: error
23: copy all the backups to the db dir
need to copy the control files, rename the binary backup of the control file and make the copies as needed
24: try to mount the db, error < must use reset logs or noreset logs >
25: need to do a recovering of the database
shutdown
restore the archive logs
startup mount;
recover database until cancel using backup controlfile;
it will ask for a log file :
yes for recovery
cancel for cancelling recovery
26: check status: open the database in readonly
alter database open read only;
check the tables to see the data
shutdown immediate
shartup mount;
recover again : recover database until cancel using backup controlfile;
if oracle is asking for a log that do nto exist , all we have to do is type cancel
27: open the database
alter database open;
need to do reset logs
alter database open resetlogs;
28: check the db that you are connected, check the tables
thanks and regards

A very long list ... let me make it shorter.
SQL> archive log list;If I see this:
Database log mode No Archive ModeI put the database into archivelog mode and leave it there forever.
If it is in archivelog mode:
RMAN> TARGET SYS/<password>@<service_name> NOCATALOG
RMAN> BACKUP DATABASE PLUS ARCHIVELOG;Though there are a lot of things one could do better such as incrementals with block change tracking, creating an RMAN catalog, etc.

Hot Backup for oracle database?

Dear all,
I want to change Cold Backup to Hot Backup. Does anyone how to do Hot Backup and has some simple document I can follow? If the database is running in ARCHIVELOG mode, is the size grow very fast or other effect will overcome?
Please advice,
Amy

I want to change Cold Backup to Hot Backup. Does
anyone how to do Hot Backup and has some simple
document I can follow?online/hot backup don’t need to shutdown the database we can put the database in backup mode and then start taking backup even though users database activity read/write data going on. This strategy useful if ours database goes for 24x7.
For online/hot backup the database should be in archive mode.
I hope you know how to turn on archive.Before turning on check the archive on or not.
SQL> archive log list
Database log mode              Archive Mode
Automatic archival             Enabled
Archive destination            USE_DB_RECOVERY_FILE_DEST
Oldest online log sequence     1
Next log sequence to archive   2
Current log sequence           2
SQL> you may also check it by connecting to database as sys
SQL> select log_mode from v$database;
LOG_MODE
ARCHIVELOG
SQL> if yours database is not in archive mode then first enable archive,please before turning on the archive take cold backup.
SQL>shutdown immediate
SQL>startup mount
SQL>alter database archivelog
SQL>alter database open;
SQL> archive log list
Now you are able to take hot/online backup ,its upto you you use user managed backup and recovery or use RMAN oracle own shipped free tool for backup and recovery ,however my recommendation would goes for RMAN.
http://download-uk.oracle.com/docs/cd/A97630_01/server.920/a96572/toc.htm
http://www.oracle.com/technology/deploy/availability/htdocs/rman_overview.htm
ARCHIVELOG mode, is the size grow very fast or other
effect will overcome?However, the growing size pace either fast or slow everyday can be impractical it alls depends on activity of yours database operation.You will have to observe it yourself by turning on archive log its vary database to database activity.

Oracle 9i backup onto Oracle 10g

Hi All,
Is it possible to restore the SAP backup taken in Oracle 9.i onto the Oracle 10g.
If possbile, can anyone share the documents for the same?
Thanks in advance,
DVRK

> You won't be able to use 9i DBFs on a 10g DB. You need to go 9i -> 9i then upgrade your "new" DB to 10g.
This is not true as stated. There is no difference in upgrading an installed 9.2 database (as shutdown, install 10.2 software and upgrade) and copying files over and doing the upgrade directly.
See (as written already)

If on other system is installed 10.2.0.3, but You still see that import is using 9.1., then probably YOu have more than one ORACLE_HOME on that machine.
set correct env variables in order to use 10g ORACLE_HOME and imp utility from it.
echo $ORACLE_HOME
echo $PATH
both should return path to 10g ORACLE_HOME.

Database cold backup in oracle 10g

Hi,
oracle-10.2g
solaris-10
The oracle database i connected with the sun cluster 3.2(two node cluster), for taking the cold backup one of the resource(instance). When I shutdown the resource(instance) for taking the cold backup. The resource(instance) starts automatically again on the same node.
Kindly provide me the solution for taking the cold backup by shutting down the instance.

Here is the procedure for taking coldbackup:
First shutdown the database then copy all the datafiles, tempfiles, control files and logfiles to a safe place using the select command. Then run the script as described here: http://tinyurl.com/bp85dmj

It seems, that the OS can´t read the label from the tape.
Is the tape device correctly configured - can you access the tape from OS level?

Importing compressed backup in Oracle 10g

Hi everyone,
I have to restore a dump from a compressed file with .exp as extension on Windows OS.
After searching the web, there were more import samples on UNIX than on Windows.
Has anyone restored a dump from a compressed file(.exp) in Windows OS? Please help.
Oracle Version:10.1.0.4.0
OS Name & Version: Windows 2003
Thank You,

Sunny.

Sunny.As an expansion on Hemant's comments, you need to be aware (if you aren't already - I'm surprised at the number of IT "professionals" who aren't) that there is no magic in the "extension" part of a file name. There are certain conventions, but they really mean nothing as far as the actual contents (data AND format) of the file. Putting a "Corvette" nameplate on my Honda Civic doesn't make it a Corvette. Putting a ".exp" extension on some unknown file doesn't make it a compressed dump file.

I see in Oracle Database 10g Product Family [Oracle Database 10g Product Family|http://www.oracle.com/technology/products/database/oracle10g/pdf/twp_general_10gdb_product_family.pdf] not support the Data Guard.
Can I do it in Oracle 10g SE ?

hi,
trouble is the cost of EE can be quite expensive
another way of creating a psuedo (hope I spelt that correctly) dataguard would be to script a method of shipping archive files to a DR server.

Oracle Hot Backup Script Windows Server 2003

Hello,
Does anyone here have a working Oracle 10I database hot backup script for Windows Server 2003? If so can you please post it here.
Thanks.

Here is a basic batch script I have used for a hot backup of Oracle databases using RMAN
Will just need to update some locations based on you environment just check all the comments and change what you need to but this can be scheduled to run regularly through the windows scheduler for database backups.
This will take a hot backup and backup the archive logs.
Let me know if you have any quesitons.

How to include Date for backup of Oracle in a script !!! LINUX

hi,
I need to add date & time for the backup of Oracle 10g on OEL 5 32 bit.
and also how do I get an email when Rman finishes its job
Thanks in advanced.

I need to include the date & time in this script.
Thanks in advanced.That's not a backup, it's an export.
I don't have my linux system handy to debug, but what you want would be something like:
expdp ..... dumpfile=exp_`date`.logThe reverse single quote (I don't know the official term, but it's the character just to the left of the one/exclamation on a US keyboard) tells the shell to substitute the value returned by the command enclosed by the marks. In the example above, it would substitute the value returned by the "date" command. That command has many, many arguments to control the format of what is returned. Look them up an any good nix reference, or just "man date". (As for any good nix reference, you should at a minimum have a copy of "Unix In A Nutshell" on your desk.)

Hot Backups - Oracle 9i, 10g and 11g

Are all hot backups run outside of RMAN as an OS file copy? If so, isn't this a very risky exercise.
I understand that RMAN will check for corruption where as hot backups won't. RMAN can also track backups in a recovery catalog.
If using a hot backup, it seems like corrupt data could be backed up with the good data.
What exactly are the advantages of using a hot backup. It is understood that the databases can be up during a hot backup, but can't they also be up with an incremental RMAN backup?

I think you need to read the documentation again. Check on tahiti.oracle.com
A cold backup is when the database is shutdown (can be done by file copy or rman)
A hot backup is when the database is running (can be done by file copy or rman)
RMAN has the advantages of backing up at block level, and going directly to tape, and compression, and incremental backup, and block checking, and backup from ASM, and catalog ......
File copy has the advantage of being logically simple (e.g you can see exactly what is happening when you copy a file).

Pls help

do we still need to take cold backupYou need to take backup. Hot or cold depends on how your DB is running (archivelog or not).
Will we have file permisions for copyng Use RMAN and don't worry about that.
