Questions on Oracle EBS backup strategy

Hi all,
Currently I am planning the backup strategy for the EBS. May I know apart from backup the database using RMAN, is there anything (e.g. log files) that I need to backup such that I can fully restore the system?
Thanks a lot in advance.
Alex

I see that this is your first post, and you have not searched on this forum or on google about n-number of responses to your question that various people have already asked.
You didn't mentioned the applicaiton version you are using.
Anyways, you need to take the complete backup of the application tier directories i.e., appl_top, common_top, inst_top, etc.

Few questions regarding Oracle Scorecard and strategy management.

Hi,
I have following questions regarding Oracle Scorecard and strategy management:
1. What are the ways in which i can show status of a KPI, like we have colors and symbols, what are others?
2. can we keep log of KPIs, store them, keep report of feedback/action taken on that?
3. Does Scorecard and strategy management have ability to retain history on feedback and log of
entries i.e. date/time, user name?
4. Does Scorecard and strategy management have ability to use common mathematical formulas e.g. median, average, percentiles. Describe.?
Thanks in advance for your help.

Oracle EBS Backup Compatibility

Hi
Right now we are using veritas net backup for Oracle EBS Backups.Due to some changes in our Infrastructure level they are planning to switch over from veritas net backup to commvault backup.
Could you please let me know whether commvault backup software is compatible with oracle EBA R12 backups?
Version Details - Oracle Apps - R12.0.4 DB - 10.2.0.5.0
Commvault - Version 8.0.0

Hi;
For your issue its better contact wiht your commvault sales person. If you use this tool just for db backup i belive its certified

Cold Oracle EBS backup and restore doesn't work

Hi,
I did a backup using tar while the database was open and not in archive mode ( archivelog disabled ) and restored it on another machine.
OS = AIX 5.3
Oracle EBS 11.5.9
Database 9i
When i started the database I got errors.
Is there a metalink document which will help me recover the database ?
I followed the following metalinks:

I understand that Hot backups cannot be done with noarchivelog and data will be inconsistent.
However, shouldn't the Database be able to recover whatever data is in there in the datafiles and startup normally. From where should it be recoverd, only if we store the data changes in a separate files. These files are called archive logs. The archive logs will be generated when you enable archive log.
This is my question and concern. I searched for Metalink and couldn't find anything on it.
I want to startup the database with whatever Data is present there after the backup. Any solutions for such a scenario ?

Specify log: {<RET>=suggested | filename | AUTO | CANCEL}When it asks for change number "637" and if you are lucky enough that the redo log file with this sequence is not over written then that redo log file can be given as input when it asks as above.
But again, all these tries are for nothing. At the end of the day if your database is in no archive log mode the reliable backup is only the one taken using cold backup method. i.e. by shutting down the database.

Oracle EBS R12 Pre - Implementations phase question air
Posted: Jun 30, 2009 10:22 AM Edit Reply
Dear all Gurus,
We are going to implement Oracle EBS r12, for industrial concern, we have following quires if any peer may suggest.
1) we heard the oracle R12 has build new release with 11g db , is it been practical for choosing it for corporate ???
2) Linux Read hat which version is more stable like 5 releases is compatible with R12 new release?
3) We are also thinking for 64 bit architecture rather than 32 bit, could any one figure out the practical pros and cons for this.
4) We are also wondering about the server machine brand and its configurations like HP DL380 G6, DELL 2850? could any one share abut his experience about the same.
5) What sort of Server configurations (Processor , 2way -4way , RAM , HD and other accessories ) for r12 Multi node setup for 150 clients (DB Server , Apps Server , Test Prod )
6) What should be backup strategies like tap backup and how much space requirements we must have provisioned for retaining almost 2~3 month backup.
7) Application implementations methodologies?
8)
I know to address our queries would be time consuming for you bust peoples , but I would really oblige for being shared your journey this would defiantly the PATH way for other like mentoring for others.
looking forward your valuable instructions ASAP.

Oracle EBS Workflow Options

Hi,
Anybody has ideas about Oracle EBS workflow strategy in the near future?
I would like to customize the workflow for GL (parallel approval) in Oracle EBS (11i/R12) and need suggestions on each option.
Options:
1. Custom Standard Oracle Workflow
This is a short term high effort customization solution.
2. Utilize Oracle Approval Management (AME)
It is available for limited modules and functions. GL module is not part of the supported modules in the near future.
3. BPEL for Oracle Apps
Not sure whether it is integrated with Oracle Apps. Need more information.
I saw a doc about migrating WF processes to Oracle BPEL but it does not have any detail info. (Doc ID: Note:394387.1)
Regards,
Jeremy

Jeremy,
The suitable choice would be either oracle workflow or the BPEL but it still depends on a lot many other factors.
The standard oracle workflow is still going to be around for many more years and is the default choice as of now.
BPEL is more versatile, more detailed but there is no apps standard for it. So even if you develop now in BPEL, there are chances that it might not be compatible/feasible with the Fusion Apps standards which we don't know yet. And there are other factors like learning a new tech and the ones Gareth has mentioned.
Read through http://shiv-saroj.blogspot.com/2008/03/oaf-vs-adf-with-respect-to-oracle.html
Its not exactly what you are looking for, but will help you in decision.

RMAN Backup Strategy Comment Needed

Hi,
Currently I'm trying to implement a backup strategy with RMAN.
Scenario: My side we're 5 days operational (Monday to Friday). I'm planning my backup as follow:
Mon – Incremental level 1 differential
Tue – Incremental level 1 differential
Wed – Incremental level 1 cumulative
Thurs – Incremental level 1 differential
Fri – Incremental level 0 (aka full database backup)
I planned Mon,Tues and Thurs as an incremental differential, while Wed as an incremental cumulative. With Wed as a cumulative backup, my thinking is that if my db is to fail on Thurs/Fri, my recovery will need to apply fewer backups but at the expense of storage.
Any comment or view about the strategy will be greatly appreciated.
Thanks and Regards

Backup strategy for ebs R12?

Hi,
I have a couple of questions regarding to backup strategy for ebs R12.
Let's say that we have one application server and one database server running, and we would like to have a backup periodically for both servers.
This means that we want to have the exactly same backup of configurations and other files for the application server and the database server in case of any fatal crashes in the servers.
I went through some discussion threads and it seems common way is to use RMAN for the data of database and file system copy for application and database servers. But, I would like to know what's the best way or recommended way for the backup strategy for data and server files of Oracle e-business suite.
Do you guys have any suggestion for this?
Thanks in advance.
Cheers,
SH

Hi SH;
I suggest check first our previous discussion
backup and recovery startegy for EBS
Re: Backup System
Backup Policy for EBS can
If you make search you can find many other thread which is mention same question
For your issue basicly what we do
1. For our prod db, if possible we take weekly cold backup(sunday) and take rman backup also daily(full backup, but it depends system you can prefer to take incremental)
2. For our system we take file system backup weekly(OS base)
3. For application we take backup every sunday(for some system 15 days or 30 days period). The most important point here if your system prod, and if you need to apply patch to your system you need to have valid backup and also need backup for after patching
One other important issue is we run preclone sh before take backup for apps and db tier

Long-term retention backup strategy for Oracle 10g

Hello,
I need design a Archivelog, Level 0 and Level 1 long-term retention backup strategy for Oracle 10g, It must be based in Rman with tapes.
¿Somebody could tell me what it's the best option to configure long-term retention backups in Oracle?, "CONFIGURE RETENTION POLICY TO RECOVERY WINDOW OF 1825 DAYS;" It's posibble ?
Regards and thanks in advance

Hello;
RECOVERY WINDOW is an integer so yes its possible. Does it make sense?
Later My bad, this is Oracle 11 only ( the gavinsoorma link ) . Getting harder and harder to think about 10. Don't think I would use RECOVERY WINDOW.
I would let the tape backup system handle the retention of your rman backups.
Using crosscheck and delete expired commands you can keep the catalog current with the available backups on tape.
Oracle 10
Keeping a Long-Term Backup: Example
http://docs.oracle.com/cd/B19306_01/backup.102/b14191/rcmbackp.htm#i1006840
http://web.njit.edu/info/oracle/DOC/backup.102/b14191/advmaint005.htm
Oracle 11
If you want to keep 5 years worth of backups I might just use KEEP specific date using the UNTIL TIME clause :
keep until time 'sysdate+1825'More info :
RMAN KEEP FOREVER, KEEP UNTIL TIME and FORCE commands

Any new backup strategy with Oracle VM 3.1 ?

Now, since Oracle VM 3.1 was released, could we be updated with backup strategy.
Backing up OCFS2 repositories allow us protect OVF files right?, but what happen with apps runing on VMs, these data is also backed up? what about open files, databases, etc.
I will appreciate any comment.
Thanks in advance.

try running this on each server:

Interview questions for oracle dba

Hi I am trying to find teh interview questions for oracle dba .
What will be your answer to the following questions. Can somebody shed some light...
. What is the day to day duties of oracle dba?
·     Did you use online or off-line backups?
·     What version of Oracle were you running?
·     Haw many databases and what sizes?
·     If you have to advise a backup strategy for a new application, how would you approach it and what questions will you ask?
·     If a customer calls you about a hanging database session, what will you do to resolve it?
·     Compare Oracle to any other database that you know. Why would you prefer to work on one and not on the other?
Thx
KK

. What is the day to day duties of oracle dba?
I have got a checklist, designed for my daily, weekly, fortnightly and monthly tasks. For example, in the daily checklist tasks, I check for the alert log file, competion and correction of my exports and operating system backups. DB space situation, Antivirus status, standby database status, space on disks, any rogue queries etc.
· Did you use online or off-line backups?
Both.
· What version of Oracle were you running?
8i(not any more), 9i, 10g
· Haw many databases and what sizes?
8 databases, ranging from 1 TB to 10 GB. I have segregated them into OLTP production, testing, cm, and development and a Datawarehouse.
· If you have to advise a backup strategy for a new application, how would you approach it and what questions will you ask?
How much they could afford to lose data or they want zero data loss and also I will get their requirements about down time and up time of database.
· If a customer calls you about a hanging database session, what will you do to resolve it?
First I will identify it, then see to it what exactly it is doing, capture that situation and then either try to release the locks(if its a blocking or blocked session), or kill the session, if its hanging on a runaway query.
· Compare Oracle to any other database that you know. Why would you prefer to work on one and not on the other?
Oracle passes the ACID rule with distinction as compared to the other databases. Moreover, the multiversion read consistency, recovery, flexibility and challenges of Oracle are matchless.

How to configure RMAN - Oracle EBS R12

Hi,
I have installed Oracle EBS R12 on OEL 5.6 and want to configure Backup strategy for Database. Database Version is 11.1.0.7. Currently Database is in Noarchivelog mode and want to take backup of database using RMAN. Can anyone guide me what are the steps to follow in order to achive that ?
Regards,
Priyanka

You can use RMAN to take backup in noarchive log mode.However you will be able to take cold backup only.
Use this,
RMAN> run {
shutdown immediate;
startup mount;
backup database;
alter database open;
Note:
RMAN does not permit you to make inconsistent backups when the database is in NOARCHIVELOG mode. If you employ user-managed backup techniques for a NOARCHIVELOG database, then you must not make inconsistent backups of this database.

Oracle Suggested Backup, to tape only - Tivoli Storage Manager

I´ve been asked to cancel future backups to disk and to setup oracle´s suggested backup to the tape device only (which underwater is the tdpo from Tivoli´s storage manager).
This way the expensive disks can be freed from recovery data.
I´ve had my share of problems with the tdpo, but besides the problem of this gateway driver between RMAN and TSM I would like to know if this is best for the whole suggested backup strategy.
Somehow I´m not convinced in backing up to "tape" devices only; for it is slower than local disks, and because we had problems before with the driver, but there may be a lot more reasosn why I should or should not accept this desired goal to be best for our company.
I hope some of you can help me straighten my vision on this.
Robin

The biggest problems I think we might face are the
big question "who is responsible for what", and the
administration of non Oracle systems/methods to
perform backupsi have no problems with such a setup. i provide the rman skript which will be called by TSM.
the TSM admins notify me if the backup failed. retention on TSM side is disabled, only RMAN deletes obsolete/expired backups.
All I want to care about is performing a backup to
Disk, or Disk and Tape, or just Tape from within
Oracle/RMAN and read the ouput from here.
Now where these external tape labraries like TSM come
in there will be more administration for the total
handling of a backup job. It´s not only RMAN, but a
tdpo and a TSM server which need to be monitored
closely. of course TSM has to be monitored but if you already have invested an infrastructure you should use it for every type of backups.
Sadly Oracle has yet to come up with it´s secure
backup for TSM systems, but I think it would be best
if I could let Oracle solely in charge of its own
backups.if TSM retention is disabled, RMAN has absolute control.
Then again, I don´t know if anyone has good
experiences with TSM as the only backup provider for
Oracle backups. (so no disk backups)it works very good. use staged pools on TSM. primary pool should be diskpool, secondary a tapepool. you can configure TSM to move the data from disk to tape based on fill level or age.
