How to hot backup 11.1.1.3 Planning application

I readed Backup and Recovery Guide. But still have no ideal about how to hot backup for planning application.
Have any metrial talk about this or it's impossible in real world. Thanks!

From version 11.1 on the "hot" backup method is:
- (1) archive the database to a file (in this time the database is read only) every night or weekend
- (2) enable transaction logs
- (3) backup these files (archive and logs) regularly
If there's an issue:
- (1) Restore from archive (gives you a downtime)
- (2) Replay transaction logs until before the issue occured
The database would available for read 24x7 - writing will be disabled only during backups.
Backup and Restore are high performance actions that will depend on disk and cpu speed. A normal Server will do 20MB/sec.
OK?

How to know the Cluster name for Hyperion Planning Application

Hi,
We have 2 Hyperion planning clusters in our Planning environment. As per new requirement, we need to make the copy the existing planning application.
We are not able to get the defined cluster information for existing planning application.
Please help on how can we find the cluster name for a Hyperion Planning application.
Quick help will be appreciated!!
Thank You.
Mohit Jain

Hi John,
Thanks for your quick response!!
We tried to run this command on Planning system command. but it did not return any record. We found that table "HSPSYS_APP_CLUSTER_DTL" does not have any record.
is there any other way, where we can check the planning cluster name.
Please help on this further.
Thank You.

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.

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 !

How to restore RMAN hot backup to another database on another server?

I want to know how to restore RMAN hot backup from production server to another database on a testing server.
The hot backup is from a database named PROD on the production server
The database to be restored with the hot backup is TEST on the testing server. There is already a PROD database on the testing server and this PROD database must be kept.
I have read some threads about changing initTEST.ora to PROD to restore such backup but (I think) will not work in my case since I already have a PROD database on the testing server.
The version is 11gR2 on Linux but the compatible parameter is set to 10.2.0.1.0.
Thanks for any help.

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.

Recovery from hot backup

I have a problem with recovery hot backup from production database to test database and open it to use.
I have 'hot backup' without temporary tablespace and roll tablespace, I cant shut down production database (24x7), please give me a regulations how to recover database from hot backup, without online redo logs, temp tablespace, roll tablespace only with archive logs, and.....after this ..rename database sid.
Every time when I recovered database, it's still want to recover...and recover from archive logs and I cant open it, it's still inconsistent.Please send me an answer for [email protected]
thanks!

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?

Using Data Guard and hot backups - 9.2.0.6.0

Hi all,
I have an existing 9.2.0.6.0 database that is setup in a DataGuard environment - one primary database with a physical standby in a separate datacenter. It is all setup and it works beautifully. On our primary database, we currently have 2 different types of backups we are doing - we do an export of the main schema (all of the application data is all in this one schema) 4 times a day, and we do a full database hot backup once a night.
My question is in regards to the hot backup - I don't know that it is even worth doing a hot backup of this database? I am trying to think of a situation where we would actually want to restore a hot backup of the primary database... If we ran into some kind of a data issue, it would probably be quickest and easiest to restore data from one of the exports, and when we did that restore (import), I assume that data change would be replicated through DataGuard to the standby site. But if there was some kind of situation where we wanted to restore a recent hot backup of the primary database, that would essentially break the Data Guard configuration, and I assume that after the hot backup was restored, we would have to somehow re-instantiate Data Guard on the standby site.
Does anyone have any input on this? If you are running with DataGuard, is it even worth it to be doing hot backups? What kind of situation would call for restoring a hot backup, instead of just failing over to the standby?
Thanks!
--Brad

If we ran into some kind of a data issue, it would probably be quickest and easiest to restore data from one of the exportsIt would be quickest to failover to stand by database than restroing from dump file. After all you maintaing stand by db for that reason.
How can you restore database up to the latest changes using export/import ? You may have to restore using rman and apply the logs.
You can backup from stand by database. You do not need to back up primary.

Steps to create the standby with Hot Backup........?????

Hi All
I am planning to create the Physical standby with Hot backup ....
Can anyboby give me the link/steps which explains how to do this?
Thanks
Gagan

To copy the file from the primary, you can use RMAN, or manual hot backup copy with begin backup and end backup mode.
You can read the doc about creation of standby database :

When i start my hot backup my database getting very slow

Hi,
I am using following commands for enabling hot backup
SQL>ALTER SYSTEM ARCHIVE LOG CURRENT;
SQL>ARCHIVE LOG LIST;
SQL >ALTER DABATBASE BEGIN BACKUP;
Database altered.
SQL>SELECT FILE#,STATUS FROM V$BACKUP;
FILE# STATUS
1 ACTIVE
2 ACTIVE
3 ACTIVE
4 ACTIVE
and using cp -rp command to copy the file (backup copying speed good) but database performance very slow
How to improve performance ...
Regards

It is very likely that you experience slow performance with ALTER DATABASE BEGIN BACKUP , because until you do ALTER DATABASE END BACKUP , every modified block is additionally written into the online logfiles . Doesn't that happen only the first time the block is modified?

The command was introduced for split mirror backups, when this period is very short. Else ALTER TABLESPACE ... BEGIN/END BACKUP for every tablespace one at a time reduces the amount of additional redo during non-RMAN Hot Backup. There appear to be only 4 files. We don't know how big or sparse they are.

RMAN doesn't need that at all - much less redo - and also archive - generation then.
Furthermore, you can use BACKUP AS COMPRESSED BACKUPSET DATABASE to decrease the size of the backup even more - if space is an issue.
In short: Use RMAN :-)
Agree with that! Unless the copy is actually going to an NFS mount or something, where I would be concerned whether it is the type of NFS that Oracle likes. I'd also advise a current patch set, as the OP didn't tell us the exact version, and I have this nagging unfocused memory of some compression problems of the "oh, I can't recover" variety.
I'd like to see some evidence on I/O and cpu usage before giving advice. When I used to copy files like this, it would choke out everyone else. RMAN was a savior, but had to wait for local SAN upgrade.

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

What are the consequences of not backing up controlfile in hot backup.

Hi All,
We have 8i,9i, 10g and 11g database. The unfortunate thing is that we are using this user managed hot backups for backing up our database. and I have no idea for what reason, we are not backing up the controlfile. Anyway, I would like you to comment on this, they said, they will recreate a text based controlfile and do the recover database until cancel using backup controlfile ; I know, if we have the path of all the datafiles , we can use this, but is this a right strategy ? of course, no one would agreed on this. I really appriciate, if somone could express his opinion in detail.
Regards

Hi,
The database consists of the following files:
Spfile/Pfile
Controlfile
Datafile
Redo Log
archivelog
When we talk about backing up the database, (no matter how) must take backup up of all these files.
If you are not taking these files in your backup you have a incomplete backup.
Why not take a back up of control file to a binary file. Is more simple and fast restore controlfile using binary file.
ALTER DATABASE BACKUP CONTROLFILE TO '/oracle/backup/control.bkp';To Trace should be used to produce SQL statements that can later be used to re-create your control file.
ALTER DATABASE BACKUP CONTROLFILE TO TRACE;Why not use RMAN? A resource with endless options and features.
Using user-managed backup you have none options/feature compared with the use of RMAN.
It can be used in all Oracle databases without additional license.

Hot backup - best practice

I have written a simple TimerTask subclass to handle backup for my application. I am doing my best to follow the guidelines in the Getting Started guide. I am using the provided DbBackup helper class along with a ReentrantReadWriteLock to quiesce the database. I want to make sure that writes wait for the lock and that a checkpoint happens before the backup. I have included a fragment of the code that we are using and I am hoping that perhaps someone could validate the approach.
I should add that we are running a replicated group in which the replicas forward commands to the master using RMI and the Command pattern.
Kind regards
James Brook
// Start backup, find out what needs to be copied.
backupHelper.startBackup();
log.info("running backup...");
// Stop all writes by quiescing the database
RepositoryNode.getInstance().bdb().quiesce();
// Ensure all data is committed to disk by running a checkpoint with the default configuration - expensive
environment.checkpoint(null);
try {
     String[] filesForBackup = backupHelper.getLogFilesInBackupSet();
     // Copy the files to archival storage.
     for (int i=0; i<filesForBackup.length; i++) {
          String filePathForBackup = filesForBackup;
          try {
               File source = new File(environment.getHome(), filePathForBackup);
               File destination = new File(backupDirectoryPath, new File(filePathForBackup).getName());
               ERXFileUtilities.copyFileToFile(source, destination, false, true);
               if (log.isDebugEnabled()) {
                    log.debug("backed up: " + source.getPath() + " to: destination: " + destination);
          } catch (FileNotFoundException e) {
               log.error("backup failed for file: " + filePathForBackup +
" the number stored in the holder did not exist.", e);
               ERXFileUtilities.deleteFile(new File(backupDirectory, LATEST_BACKUP_NUMBER_FILE_NAME));
          } catch (IOException e) {
               log.fatal("backup failed for file: " + filePathForBackup, e);
saveLatestBackupFileNumber(backupDirectory, backupHelper.getLastFileInBackupSet());
finally {
     // Remember to exit backup mode, or all log files won't be cleaned
     // and disk usage will bloat.
     backupHelper.endBackup();
     // Allow writes again
     RepositoryNode.getInstance().bdb().quiesce();
     log.info("finished backup");
The quiesce() method acquires the writeLock on the ReentrantReadWriteLock.
One thing I am not sure about is when we should checkpoint the database. Is it safe to do this after acquiring the lock, or should we do it just before?
The plan is to backup files to a filesystem which is periodically copied to offline backup storage.
Any help much appreciated.

James,
I am using the provided DbBackup helper class along with a ReentrantReadWriteLock to quiesce the database. I want to make sure that writes wait for the lock and that a checkpoint happens before the backup. One thing to make clear is that you can choose to do a hot backup or an offline backup. The Getting Started Guide, Performing Backups chapter defines these terms. When doing a hot backup, it's not necessary to stop any database operations or do a checkpoint, and you should use DbBackupHelper. On the other hand, when doing an offline backup, you would want to quiesce the database, close or sync your environment, and copy your .jdb files. In an offline backup, there is no need to do DbBackup.
So while it doesn't hurt to do all of the steps for both hot and offline backup, as you are doing, it's more than you need to do.
You may find the section on http://www.oracle.com/technology/documentation/berkeley-db/je/GettingStartedGuide/logfilesrevealed.html informative in how it explains how JE's storage is append only. This may help you understand why a hot backup does not require stopping database operations. If you want to do a hot backup, the code you show looks fine, though you don't need to quiesce the database or run a checkpoint.
If you are running replication, you should read the chapter http://www.oracle.com/technology/documentation/berkeley-db/je/ReplicationGuide/dbbackup.html. Backing up a node that is a member of a replicated group is very much like a standalone backup, except you will want to catch that extra possible exception. Also note that backup files belong to a given node, and the files from one node's backup shouldn't be mixed with the files from another node.
To be clear, suppose you have node A and node B. The backup of nodeA contains files 00000001.jdb, 00000003.jdb. The backup of node B contains files 00000002.jdb, 00000003.jdb. Although A's file 0000003.jdb and B's 00000003.jdb have the same name, they are not the same file and are not interchangeable.
In a replication system, if you are doing a full restoration, you can use B's full set of files to restore A, and vice versa.

Rman hot backup

hello
i am using rman hot backup script to take backup database everyday but the problem is it is working but not deleting old backup older than 2 days .
also i have question .. my database is in archive log mode and everyday about 6-7 .arch files generating in my archive directory.
it is not deleting the old files but generating new files everyday so adding up to the space.
SQL> show parameter archive
NAME TYPE VALUE
archive_lag_target integer 0
log_archive_config string

log_archive_dest_1 string
also should i set dest_1 as archive location or just log_archive_dest
whats is the difference.?
my rman script is

RMAN never deletes the Backups unless there is a space pressure in the Recovery Area. Instead it marks the Backups as OBSOLETE based on Retention Policy (in your case it is 2 Days),
To confirm it SET DB_RECOVERY_FILE_DEST_SIZE to some smaller value, the RMAN will remove all the Obsolete Backups automatically to reclaim space.Be very careful with this. If you generate a LOT of archivelog files and you exceed this size, on the next archivelog switch your database will hang with "cannot continue until archiver freed". RMAN will not automatically remove anything. RMAN only removes stuff when you program it in your script.
See:
http://docs.oracle.com/cd/E14072_01/backup.112/e10642/rcmconfb.htm#insertedID4 Retention Policy (recovery window or redundancy)
things like:
set retention window and number of copies
crosscheck backup
delete obsolete <-- delete old, redundant, no longer necessary backups/archivelogs
delete expired <-- NOTE: If you manually delete files and do not execute delete expired (missing file), the DB_RECOVERY_FILE_DEST_SIZE remains the same. So, you can clean out the space and oracle will still say the location is "full".
Understand that if you also set this parameter too small and your backup recovery window/redundancy are incorrectly set, you can also exhaust the "logical" space of this location again, putting your database at risk. Your parameter could be set to 100G on a 400G file system and even though you have 300G available, Oracle will see the limit of this parameter.
My suggestion, get in a DEV/TEST environment and test to see how to best configure your environment for RMAN database backups/control file, archivelog backups also taking into consideration OS tape backup solutions. I always configure DISK for RMAN backups, then have some other tape backup utility sweep those locations to tape ensuring that I have sufficient backups to reconstitute my database - I also include a copy of the init.ora file, password file as well as the spfile backup in this location.
>
In case of Archivelogs, It is better to create and execute a Purge Job to remove Archivelogs after backup them on tape.I almost agree. I try to keep all archivelogs necessary for recovery from last full backup online. I try to keep a full backup online as well. much faster at restoring stuff instead of trying to locate it on tape.
