Automating refreshing one system with the rman hot backup copy from another

Hi Apps DBAs,
Right now we have two systems: production (OPEBSN) and production support (FINSUP).
I implemented a cronjob, which can refresh FINSUP every night from the cold backup of production. We shutdown the production system at night.
But our istore on production will go live soon and our production system will run 24*7.
The production is already hot backed up from RMAN.
Is it possible to do the following?
Automating refreshing FINSUP from the RMAN hot backup of OPEBSN?
If it is possible, would you please outline the general idea or give me a reference documentation?
If it is not possible, is there any other way to realize our purpose?
Thank you in advance!
Lily

I have one doubt with the RMAN

Hi everybody,
Is there possible to store the RMAN backup in the different domian.... for example oracle is installed in the database1 domain and we can store the RMAN in database2 domain.
Thank You

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 string /u03/archive_logs/DEVL
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 Hot backup.unix script
The RMAN hot backup script rman_backup.sh:
# !/bin/bash
# Declare your environment variables
export ORACLE_SID=DEVL
export ORACLE_BASE=/u01/app/oracle
export ORACLE_HOME=/u01/app/oracle/product/11.2.0/db_1
export PATH=$PATH:${ORACLE_HOME}/bin
# Start the rman commands
rman target=/ << EOF

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.

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.

Can I install Adobe Creative Cloud in more than one computer with the individual plan?

I don´t have clear about the diference between individual plan an teams. My questions are:
Can I install Adobe Creative Cloud in more than one computer with the individual plan?
The team plan means that I have to pay for US$70 for each computer that i want to install the creative cloud even if I am the only user?

Hi heymarusia,
Yes, you can install and activate Creative Cloud desktop applications on two computers, regardless of operating system, for the individual associated with the Creative Cloud membership. See the product license agreements page for more information.

Compliance Calibrator 4.0: replace whole ruleset on one system with another

Hi All,
We have two R/3 environments (one's at 4.7 the other is 4.6c). Both are running CC 4.0. What's the best way to replace the whole SOD ruleset on the 4.6c system with the one from our 4.7 system. When I say whole ruleset I mean all the risk, function, and business process area tables then regenerating all the rules. I don't care if the 9-digit risk ID's are identical in each system. And I don't want to copy any of the mitigation information to the other system.
I looked at the download/upload utility and it seems to deal with the generated rules. The text files it downloaded do not appear to contain anything resembling the function or risk tables. I assume we want to do more of an export/import activity similar to an upgrade conversion or new install (but using the risks and functions from our other system instead of the default set supplied by Virsa.) I can extract the tables I want (/virsa/bussproct, /virsa/funtiont, /virsa/functtcd, /virsa/functobj, /virsa/risks, etc.) and manipulate them into whatever is needed. But I'm not sure how to delete the existing tables contents and import my data from the other system.
Thanks in advance,
Doug

Hi Doug,
How did you replace rule sets in one system from other system? Please explain if you have resolved your issue. I am doing same.

Deploy from one system to the next

I have built an intranet application in HTMLDB for a client, and they are asking me for an easy way to deploy the applcation from one system to the next, say from develop to test and then from test to production.
Their wish is to do this with the push of one button, now I know that that is quite hard to realize, but I'd like to know how you people do that. Right now all i can think of is remember what you changed, export it and import it into the new application, but that's quite a hassle.
I found the export script in the utilities, but I haven't look at it closely enough to be able to reverse that process, is that the way it should be done?
Wendy

I can't believe that we are at version 2.0 now and
that there is no decent solution to export and import
what we made as a whole instead of all these separate
things.Sad, but true.
I have to explain to my customers who want to be able
to work with HTMLDB that when they want to deploy an
application from one environment to the next they
have to:
- export an application
- export the css files
- export the images
- download the static files (because they can be
exported but not imported(!) )
- create a ddl of the schema
- export csv files from the data in the tablesSounds like an opportunity to write a new utility. ;>)
and then import it all one by one in the new
environment
and then hope they didn't forget anything and have to
debug to find the differences between environments.
Am I the only one that is running into this problem?No. Anyone that's developing and deploying production apps is in the same boat. Obviously, there are varying tolerances and circumstances that make this more or less of a pain for each of us.
I am solely talking about the stuff in the database
now, not the files on the filesystem.....If it's all in the database (which we know it is) then you can certainly bundle all of those steps into a nice little package (pun intended). Let us know how it comes out!

RMAN hot backup requires archivelog all the time?

Hi all,
consider the case: a dml operation is running in oracle 11g database. after sometime it got completed and issued a commit statement. Now i took a full database hot backup using rman. but dint take archivelog backup(its must i know, but i want to know whether we can do incomplete recovery using only the full database backup and open database using RESETLOGS option?
Kindly let me know whether we can do incomplete recovery using only full database backup or we must need archivelog to open the database?
Regards,

Say your BACKUP DATABASE begins at 01:00am and finishes at 01:50am. At the minimum, you need to backup the Archivelogs from 01:00am to the first archivelolg after 01:50am. Technically you don't need the archivelogs of before 01:00am. However, if you want the ability to do a point in time recovery (which is a MUST for any production database), you would also backup the "earlier" archivelogs which can be used with the previous database backup.
Your commit does NOT guarantee that the database files are immediately updated -- DBWR "lazily" defers writing to the database files. Your commit is preserved in the online redo log. This has to be archived as an Archivelog and backed up.

If you registrate one Apple ID for each iPhone/iPad, you'll get 5GB on iCloud for each Apple ID, right? I have two iPhones and one iPad with the same Apple ID, why can't I get 5 GB fo each of them?

If you registrate one Apple ID for each iPhone/iPad, you'll get 5GB on iCloud for each Apple ID, right? I have two iPhones and one iPad with the same Apple ID, why can't I get 5 GB fo each of them?

Actually, everyone missed one point, when a device is priced, the cost of icloud storage space for that device is also included in it that is why they are able to give you 5gb each for each user ID, in nutshell there is nothing free coming with apple device purchase, it is paid for. What they are trying by giving only 5gb per user ID irrespective of the number of devices used is pure broadlight looting, they take money from you when you buy each device and give you nothing, This is a case of goods and services bought but not fully deliverd ie apple can be suied for discreminatory treatment towards it's users. I wonder why no one tried this yet in America where everyone sue everyone for petty things..... there is no one to take up this issue? . if tim got any love for the guys who shell out money for the devices his company makes, he should be implimenting this as priority before someone wake up from sleep and sue him.

I'm trying to change my ICloud e-mail to match the one associated with the Apple ID? Can someone tell me how to do this? Seems like the phone won't accept the new one, the message states "you already have acct associated....." (a given!!) I need help !!

WebLogic Error : Registered more than one instance with the same objectName

HI there, I'm facing a big problem. I have two environments installed on the same physical machine.
I have ALSB and WLI servers running out there.
Environment 1 - WLI port running at 7011 domain name : stp_wli_domain and ALSB port running at 8011 domain name: stp_alsb_homo1 - folders- stp_wli_domain / stp_bea_alsb_homo
Environmnet 2 - WLI port running at 7211 domain name : stp_wli_domain2 and ALSB port tunning at 8211 domain name : stp-alsb_homo2 - folders - stp_wli_domain2 / stp_bea-alsb_homo2
Everything was working fine, but these days I had install new deployments on both environment and I got this error :
java.lang.IllegalArgumentException: Registered more than one instance with the same objectName : stp_wli_domain:ServerRuntime=wli_wls01,Name=stp_wli_domain,Location=wli_wls01,Type=AIRuntime new:com.bea.wlai.management.AIRuntimeMBeanImpl@bcf22dc existing com.bea.wlai.management.AIRuntimeMBeanImpl@de02e6c
The weird is : There is no same object name, as you can see, domains are different, folders are different and ports are diferrent, including multicast addresses.
Have you guys seen this before ?
I'm under pressure here, 'cause some projects had stopped to work.
Please I would appreciate any help.
Tks.
Edson

HI there, thanks for attention..
See ...
There's a lot of confusion with these env's .
I did not built this, so... I'm cleaning my hands.... anyway... :)
I must fix....
Well basically if we have two env's, so we have different project each one right ?
Ok, but I was told that if you have on the same network and same physical machine the name of AdminServer as "AdminServer" in all domains, so it goes with problems... I never heard about it... but is a good practice you put the names for example :
WLI - WLIAdminServer
ALSB - AlsbAdminServer
WLI2 - WLiadminServer2
ALSB2 - ALsbAdminServer2
I would do it.. this way..
But how it wasn't me...
We got..
WLI - WliAdminServer
ALsb - AdminServer
WLI2 - AdminServer
ALsb2 - AdminServer
Have you got it ?
So... I was told that this could be a problem, almost all AdminServers with the same name... guess what ?Some Projects are back to work. but not at all.. only some.. so I 'm breathing better now... but I would like to know if you seen this before ?
I would appreciate your help again.
Unfortunately there's no detailed stack trace to track this
Tks.

[HP Expert Day] "You are not able to restore this system with the media"

Welcome to HP Experts day!
I've got a long-standing problem since last year. Let's see if you can solve this!
I'll get straight to the point :
I am unable to perform recovery on my system. This is the error message :
It's a USB recovery media created with the HP recovery media utility on the same laptop. Tested to work correctly before I sent it for RMA on my SSD. It initially was running on a micron SSD. When I got it back, it was a samsung SSD instead, according to some benchmark results.
Laptop : HP Envy Spectre XT 13-2018TU
P.S I've already opened another thread on this last year.
http://h30434.www3.hp.com/t5/Notebook-Recovery/Unable-to-boot-from-USB-recovery-media/m-p/2197929#M1...
But they were stumped.

I had this exact same issue on a Spectre XT Pro Ultrabook.
The original SSD failed and I was sent a replacement, was fortunate enough to be able to create a Recovery USB stick using the wizard in Windows. When booting from USB I received the message "You are not able to restore this system with the media".
SOLUTION: You must NOT use the Recovery USB stick in any USB3.0 port (labelled SS). Using another USB port prevented this exact error message from appearing and I was able to complete the system restore process.
I hope this helps someone, I signed up and posted here especially for this reason!

Dear Paul, thank you very much for your time and answer, I followed those steps, somehow it helped the performance of my Imac, is faster now, but the screen issue about the very High contrast colours is still there. Since I am a photographer I am very depending on the screen calibration. I am worried that I came to damage the video card when I shut down the computer from the swicth when It was frozed.
