Hot Backup Cloning

Hi Hussein and Fadi,
Do you have any experience on doin Hot Backup Cloning of Oracle Apps 11.5.10.2.
Can you please share your experience

the issue here is in the database part
i use the following steps
-run preclone
-Copy the Application tier file system (same as normal cloning)
-Copy the Database tier file system
here i put all the tablspace in backup mode
alter tablespace tablesacpe_name begin backup;
-Copy the data files
When finish the copy we have to execute the following sql statement on the source database:
-Put the database back in normal mode.
Alter tablespace tablesacpe_name end backup;
ALTER SYSTEM ARCHIVE LOG CURRENT;
-Copy Archive logs
after that you can start working in the target env. for the database you have to
-fix init.ora to reflect new paths and new sid
-start the database nomount.
-create control file manual.
-alter database mount.
-recover the database.
hope that helped

Unique Error while doing hot backup Cloning!

Dear All,
I am using EBS 11.5.10.2 with DB 9.2.0.6.
I am doing hot backup cloning by referring *[Cloning Oracle Application 11i /R12 with Rapid Clone - Database (9i/10g/11g) Using Hot Backup on Open Database|https://metalink2.oracle.com/metalink/plsql/ml2_documents.showDocument?p_database_id=NOT&p_id=760772.1]*
I am facing a unique issue, when I run adcfgclone.pl dbconfig <my_context_file>, application of my Production Server start misbehaving and it gives me an error:
Node Id does not exist for the current application server id.When I check the FND_NODE table I found that there server id was empty in it.
I have to run than run the following steps as the resolution:
1. Shutdown all the services.
2. EXEC FND_CONC_CLONE.SETUP_CLEAN;
3. COMMIT;
4. Run AutoConfig on all tiers, firstly on the DB tier and then the APPS tiers,to repopulate the required system tables.
5.start all the services and verify the issue.
Than application behaves normally.
Is there any additional step to be followed while Hot Backup Cloning other than mentioned in the above mentioned ML Doc?
Please suggest,
Anchorage :)

This is very strange, how come this happens in Production, when you are doing cloning in TEST/DEV instance.
Is there any additional step to be followed while Hot Backup Cloning other than mentioned in the above mentioned ML Doc?I feel there are no other additional steps, as I Recently did successfully hotbackup cloning using the same document.

RMAN & Hot backup cloning taking long time

Dear DBAs,
We are doing both RMAN & Hot backup cloning foe that taking more time to restore data files to TEST instance. scp taking too much time to copy to target server because of its volume of data (1.5 TB) & Mounting the RMAN backups drive on test server and restoring from that drive taking more than 8 hours.
I heard that some companies are using some device to move heavy volume Hot backup copy from source to dest faster for clone the instance easily with in minutes. What is that device name to take hot backup copies from source and restore it in target server.
Test server Specs
Processor 8 cores with 32GB Memory.
Thanks
DBA

Hot backup is not recommanded for the database size more than 1T.
RMAN backup and restore is the only opiton available for a DBA.
Other option is to use EMC Symmentrix/BCV's/Snapshots. EMC uses pair of disks to achive synch the produciton data with test server. read more about EMC symmentrix or ask your storage team.

Hot backup cloning in ebs r12

HI i was doing the hot backup cloning in ebsr12.
i have backed up the control files and datafiles and the trace file also.
i have done the steps till copying the db and apps tier.
next is
2) Create the target database control file manually
Open the backed up control file
a. remove all lines before the startup nomount statement
b. Modify the REUSE to SET
c. Modify Source DB SID to Target SID (Here PROD to TEST)
d. Modify NORESETLOGS TO RESETLOGS
e. delete all lines after the CHARACTER SET statement
i am not sure about editing the control file ....
I am a started in db's
can anyone help me in this?

HI i was doing the hot backup cloning in ebsr12.
i have backed up the control files and datafiles and the trace file also.
i have done the steps till copying the db and apps tier.Looks like you are doing cold backup and not hot backup! Was the database cleanly shutdown before copying the database files?
a. remove all lines before the startup nomount statementCorrect -- Or you could leave those lines if they are commented.
b. Modify the REUSE to SETCorrect.
c. Modify Source DB SID to Target SID (Here PROD to TEST)Correct.
d. Modify NORESETLOGS TO RESETLOGSCorrect.
You will also have to change ARCHIVELOG to NOARCHIVELOG -- If your source instance is in ARCHIVELOG mode.
e. delete all lines after the CHARACTER SET statementKeep the lines/command that open the database and create the temporary tablespace.

Hot Backup cloning vs Cold Backup CLoning

Hi,
when we do cold backu cloning...we get same data as production database..
when we do hot backup cloning..i think we will loose current transactions which are recorded in redo log and not archived ....am i right?????
when we do hot backup cloning....all the database files headers are freezed..means...all latest changes are not copied while we copying datafiles to test machine...but those changes are logged in archived log files...we will get these changes in archived log files...
am i right?????
please correct me if i am wrong.....

When all is said and done there is really no difference in the clone database made from a cold backup or a hot backup as both are point in time recoveries.
In the case of the cold backup the source database was made unavailable to users while the backup was taken. If you have that luxary then that is fine, but many sites would need or want to keep the source available while the backup runs.
The backup type should not be an issue unless you really need to capture the source database with the data in a specific known state where no changes were taking place.

RMAN hot backup cloning problem..need a way out

I took hot backup from server A using RMAN
I prepared server A by running preclone on apps and db tier
I copied apps tier and dbTier(tech_st) from server A to server B..Apps and db tier were up and running during the copy.I also copied the RMAN backup sets
now on server B, what should i do..RMAN backup is in backup sets and i need to restore it on server B(Target server)
I am following note 406982.1 for cloning steps..
in advanced clonign options, it doesnt specify to run adcfgclone on apps tier too
please guide
help appreciated

Hi,
The document assumes that you are aware of the RMAN backup, and you know how to duplicate the database.
Oracle Database Documentation
http://www.oracle.com/technology/documentation/database.html
Search this forum for "RMAN Duplicate" there are many documents referenced as this topic was discussed many times before.

RAC Cloning using hot backup

Hi,
can somebody help me with the steps for cloning 2 node to 2 node RAC, using hot backup.
Thx.

Actually, the procedure to clone a RAC database do not differ substantially from those of a single-instance database.
You can perform your cloning as if it is a single instance database and once you have your single instance up, you just have to add another instance - and the high level steps would be:
1) Preparing the init.ora file for the second instance.
2) Adding the redo logs for thread 2;
3) Updating the OCR

Clone from hot backup failing with ORA-19870, 19505 unable to find backup

Ok, the steps I am taking worked previously, the only thing that I know changed was the underlying file system and I am perplexed but then again I am not the most experienced dba so please forgive if I miss something obvious.
My steps are: create backup using:
backup database tag= tagname format '/archive/stage/DBNAME/%U';
backup archivelog all format '/archive/stage/DBNAME/%U';
backup current controlfile '/archive/stage/DBNAME/%U';
Then on the new server, I copy the files over to the new server and:
connect target username@prod
connect auxillary
set until time
duplicate target database to "PRODSBX"
etc...
The problem is the duplicate is not looking at my '/archive/stage/DBNAME' directory for the backup. It's looking in the normal backup directory on that prod box that it can't connect to... can anyone give me clues as to what I should be looking at to figure out why? I looked at file permissions in case it couldn't access this directory, I looked at id, group etc... and I am not seeing anything. These exact same scripts worked before... the only thing I have edited is the set until time so I just can't figure out why it's not going to the /archive/stage.
Any light shed in my general direction would be greatly appreciated.
Thanks!
Va.

I have no way to copy the output of the files as this is on a closed network. If there is any particular information you are looking for I'd be happy to post it.
The restore is looking for the default backup location as specified in my rman configuration but in my backup script, I specify a different location that I do the hot backup to. The first time it took this location and successfully cloned to the new server and now it seems to be ignoring it. I am not sure why, any suggestions in what I should look at, if this is a possible configuration issue on my clone server or on my primary?
Thanks,
Va.

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.

How to find out which archived logs needed to recover a hot backup?

I'm using Oracle 11gR2 (11.2.0.1.0).
I have backed up a database when it is online using the following backup script through RMAN
connect target /
run {
allocate channel d1 type disk;
backup
incremental level=0 cumulative
filesperset 4
format '/san/u01/app/backup/DB_%d_%T_%u_%c.rman'
database
}The backup set contains the backup of datafiles and control file. I have copied all the backup pieces to another server where I will restore/recover the database but I don't know which archived logs are needed in order to restore/recover the database to a consistent state.
I have not deleted any archived log.
How can I find out which archived logs are needed to recover the hot backup to a consistent state? Can this be done by querying V$BACKUP_DATAFILE and V$ARCHIVED_LOG? If yes, which columns should I query?
Thanks for any help.

A few ways :
1a. Get the timestamps when the BACKUP ... DATABASE began and ended.
1b. Review the alert.log of the database that was backed up.
1c. From the alert.log identify the first Archivelog that was generated after the begin of the BACKUP ... DATABASE and the first Archivelog that was generated after the end of the BACKUP .. DATABASE.
1d. These (from 1c) are the minimal Archivelogs that you need to RECOVER with. You can choose to apply additional Archivelogs that were generated at the source database to contininue to "roll-forward"
2a. Do a RESTORE DATABASE alone.
2b. Query V$DATAFILE on the restored database for the lowest CHECKPOINT_CHANGE# and CHECKPOINT_TIME. Also query for the highest CHECKPOINT_CHANGE# and CHECKPOINT_TIME.
2c. Go back to the source database and query V$ARCHIVED_LOG (FIRST_CHANGE#) to identify the first Archivelog that has a higher SCN (FIRST_CHANGE#) than the lowest CHECKPOINT_CHANGE# from 2b above. Also query for the first Archivelog that has a higher SCN (FIRST_CHANGE#) than the highest CHECKPOINT_CHANGE# from 2b above.
2d. These (from 2c) are the minimal Archivelogs that you need to RECOVER with.
(why do you need to query V$ARCHIVED_LOG at the source ? If RESTORE a controlfile backup that was generated after the first Archivelog switch after the end of the BACKUP ... DATABASE, you would be able to query V$ARCHIVED_LOG at the restored database as well. That is why it is important to force an archivelog (log switch) after a BACKUP ... DATABASE and then backup the controlfile after this -- i.e. last. That way, the controlfile that you have restored to the new server has all the information needed).
3. RESTORE DATABASE PREVIEW in RMAN if you have the archivelogs and subsequent controlfile in the backup itself !

Question on recovery from Hot backup

Whenever I tried to recover from my hot backup using recover database untill cancel (or any other until option)..
I get messages similar to the following :

I have all my archive files in the archive dest location.
Is there any way to prevent this warning messages and let oracle find all the archive files?
As you can see from the messages, Oracle is finding the correct file, then why there is an error message and why we have to provide the file names one-by one.
Please help !!!

Oracle will look for needed archive logfile from your log archive destination.
If you are sure all these files are under /d01/oradata/devl/arc/, you can input AUTO, Oracle will work down the list until done.

Complete Recovery from HOT BACKUP

One of our server had media failuer. We are rebuilding new server and reinstalling oracle on it. I have hot backup of instance which I would like to recover.
Can I have steps please. I will appreciate your help...!

Hi,
What is the OS and version of Oracle?
Do you have all the archivelogs after the hot backup? Is the backup a valid backup? Is it a RMAN backup or normal file system backup of the datafiles?
