Preferred Back up strategy in ECC 6.0, Oracle DB, Windows
Dear Basis gurus'
Customer using separate back up tool for backing up the back up folder. Is it required to schedule disk back up through DB13 or ask them to copy directly the data files on incremental.
Kindly help me
Regards
Joseph
Hi !
If you use a partial data backup as your daily backup, you must perform a
complete data backup at least once a week. There must be at least four
complete data backups contained in the backup cycle.
The log information should be backed up at least once a day. SAP recommend that you always have two different backup media containing the same information.
Perform a data and log info backup with verification of the backup media
at least once in the backup cycle.
You can use DB13 to schedule this, or any other solution (ex crontab)

According to Apple, I have a corrupt Leopard install and I need to back up my Mac and clean install Leopard again. I had originally intended to use Time Machine for my back ups, but since I also have a Airport Extreme, I wanted to use a HD connected to this for my back ups. Unfortunately, this won't work; the HD must be connected directly to the APE.
So, I am looking for the best back up strategy that will -
1) Let me back up all my info to a external drive, so I will have everything I need to get my Mac back in the same shape it was after I reinstall Leopard, i.e. everything on it, including mail, itunes, photos, etc. I can connect directly to a drive for this part.
2) After this, I want to back up 2 Mac Book Pros regularly to the external drive connected to the Air Port Extreme. I would like to be able to access this back up in a native format, i.e., find a file and open it from the back up without having to restore it or any other gymnastics. I don't know if Time Machine is the best solution; looking for suggestions.
Is this possible?
Thanks for your help!Hi,
1. Get the biggest external drive you can afford. You cant have enough storage space.
2. Use Carbon Copy Cloner from here...
http://www.bombich.com/software/ccc.html
That will clone the entire content of your computer on to the external.
3. Time Machine won't work in this scenario. As I understand it, Wireless back ups were removed from the list of goodies in Leopard at the last moment. It may become available in later releases of Leopard. It may not.

We are currently in the process of developing a new back up strategy for Oracle Application .
What I understand currently is
- RMAN can be used to back up the dbf files.
- The application tier does not need to be backed up unless there is a patching or customization. The probability of this seems less in production. However we may need to back up the concurrent manager logs/output files.
In application tier, the strategy seems to be copy the relevant directories to a tape or a disk drive maybe on a daily basis. This is a hot back up and hence there might be a data loss. Is this correct ?
But there are some directories which cannot be copied hot. Which are those ? Is there any solution apart from going offline the least amount of time?
So what is a good strategy for backing up the application tier ?Hi,

In application tier, the strategy seems to be copy the relevant directories to a tape or a disk drive maybe on a daily basis. This is a hot back up and hence there might be a data loss. Is this correct ?There will be no data loss at the application side as all the data are stored in the database. If you have no customization or patching on daily basis, then you need to backup log files and concurrent requests log/output files.
But there are some directories which cannot be copied hot. Which are those ? Is there any solution apart from going offline the least amount of time?What is the OS? If you are on Linux/Unix, you should be able to copy the files, but on Windows this is not possible.
So what is a good strategy for backing up the application tier ?I believe having a weekly offline backup should be enough. For the daily changes, consider taking a backup of the log/output files mentioned above.
Please search this forum for similar topic, and you will find many hits.

Start up disk is full, and need new storage and back up strategy
I am maxed out on nothing my iMac and Mac book pro and recognise I need to introduce a new external hard drive into the equation.
I currently have an apple time capsule with 2gb drive, that backs up the 600g iMac and 250g mac book.
I would like to understand if I could point applications such as iTunes, iPhoto and iMovie towards an external drive ( as long as it is always connected to either the machine...or perhaps network so all machines have access to the external drive)....and hopefully I would also be able to access my iTunes library ( on the external drive) via an Apple TV...without any fuss.
I would also like to use my apple time capsule to back up from both the iMac and Mac book internal drives...as well as recognising the data on the external drives that points to the respective computers.....eg the iTunes library etc.
Is this at all possible???
If so, which external hard drive solutions should I use ( I have seen some mention synology...but looked at the website, and so many models and not sure what I would need)???
And how would I go about lifting and shifting data, redirecting applications to read and write to external drives, and getting time capsule to back up as above.....and possibly even have an additional back up strategy that allows me to take regular copies of all hard drives and keep content in an off site location for data security...possibly in a bootable format???
Welcome all help and advice please.You should never, EVER let a conputer hard drive get completely full, EVER!
With Macs and OS X, you shouldn't let the hard drive get below 15 GBs or less of free data space.
If it does, it's time for some hard drive housecleaning.
Follow some of my tips for cleaning out, deleting and archiving data from your Mac's internal hard drive.
Have you emptied your iMac's Trash icon in the Dock?
If you use iPhoto, iPhoto has its own trash that needs to be emptied, also.
If you store images in other locations other than iPhoto, then you will have to weed through these to determine what to archive and what to delete.
If you use Apple Mail app, Apple Mail also has its own trash area that needs to be emptied, too!
Delete any old or no longer needed emails and/or archive to disc, flash drives or external hard drive, older emails you want to save.
Other things you can do to gain space.
Once you have around 15 GBs regained, do a search, download and install OmniDisk Sweeper.
This app will help you locate files that you can move/archive and/or delete from your system.
STAY AWAY FROM DELETING ANY FILES FROM OS X SYSTEM FOLDER!
Look through your Documents folder and delete any type of old useless type files like "Read Me" type files.
Again, archive to disc, flash drives, ext. hard drives or delete any old documents you no longer use or immediately need.
Look in your Applications folder, if you have applications you haven't used in a long time, if the app doesn't have a dedicated uninstaller, then you can simply drag it into the OS X Trash icon. IF the application has an uninstaller app, then use it to completely delete the app from your Mac.
Download an app called OnyX for your version of OS X.
When you install and launch it, let it do its initial automatic tests, then go to the cleaning and maintenance tabs and run the maintenance tabs that let OnyX clean out all web browser cache files, web browser histories, system cache files, delete old error log files.
Typically, iTunes and iPhoto libraries are the biggest users of HD space.
move these files/data off of your internal drive to the external hard drive and deleted off of the internal hard drive.
If you have any other large folders of personal data or projects, these should be archived or moved, also, to the optical discs, flash drives or external hard drive and then either archived to disc and/or deleted off your internal hard drive.
Good Luck! -
SAP ECC 6.0 Behavior on Windows 2003 MSCS
Dear Experts,
I have SAP ECC 6.0 run on Windows 2003 Enterprise SP 64-bit Cluster (MSCS) and when we run testing on failover we got the following result:
All cluster groups in node1 - Shutdown Node 1 - Node 2 Up
- Whoever login to Node 1 will be disconnect during failover
- Whoever login to node 2 and run transaction during failover will be hang till failover done successfully
- Whoever login to node 2 and only run the transaction after the failvover done will not feell any disruption
- New logon session is failed until basis is bringing online the following in cluster administrator under SAP Group (SAP SID 00 Service & SAP SID 01 Service)
The same result if we shutdown Node 2 and all cluster group failover to node 1.
Both services are install local in each node and start option has been made "manual"
My question:
1. Is the above result is common?
2. Is there anyway to make SAP SID 00 & 01 to be automatic failover?
Regards
Rian WHi Rian Wisandano,
All your questions/queries looks common to me...
In any given scenario, resources both SAP & DB based resoureces have to be online for you to access/logon to the system using SAPGUI. And it's very common that, unless resources (either service or instance specific) are online at cluster level the corresponding resources in SAP MMC won't be online. In your query one of that was, about 00 and 01 services, YES they are 2 different instances of your SAP build and corresponding entries at cluster level.
And it's expected behavior that, while fail-over or fail-back of cluster resoureces from one cluster node to other cluster possible cluster node that, resources goes into offline and then mover over/move back and then comes online. So as its a thumb rule for given seconds/minutes (based on the resources) resources at cluster level will be offline before they come online. So during this time you will not be able logon to your SAP system because its not only cluster resoureces but also SAP MMC corresponding entries also will be offline....Along with cluster resources come online the resources/entreis in SAP MMC also comes automatically.
And it's correct to setup, Cluster Service to 'Manual' in High Availabilty Setup.
New logon session is failed until basis is bringing online the following in cluster administrator under SAP Group (SAP SID 00 Service & SAP SID 01 Service)
The same result if we shutdown Node 2 and all cluster group failover to node 1.
I hope this helps you to understand the behavior of cluster.
Revert back if any further clarification required.

SRM 4.0 (oracle 9.2) and ECC 6.0 (oracle 10.2) compatiblity
Dear Experts, have a question reqarding compatibility of SRM 4.0 (SRM SERVER 500) on Oracle 9.2 with ECC 6.0 (Oracle 10.x).
Currently we are on SRM 4.0 (Oracle 9.2) and R/3 4.6c (oracle 9.2) and we wanted to know if SRM 4.0 will work with ECC 6.0 on Oracle 10.2. Ours is Classic Scenario and the PR/PO are all created on the backend R/3 system for the SRM shopping cart.
Also the same concern for BW 3.5 (Oracle 9.2) with ECC 6.0 (Oracle 10.2). Currently they both use Oracle 9.2. We will not be using the BI Component in ECC , but will continue to use the BW which is running on its own instance. Also I could not find any SAP document that clearly states that the Oracle versions could be different for different components. Please help clarify and direct me to the documentation link. Thanks
Regards

Problem to come back from sleep mode in Lenovo Thinkpad T400 using Windows XP
Problem to come back from sleep mode in Lenovo Thinkpad T400 using Windows XP. Each time closing the T400 lid and try to make the laptop into a sleep mode for some time, it does not properly come out of sleep mode. Login screen is able to see when opening the lid for the first time, but it only seen for a while before then a black screen on T400 Thinkpad appears. Sometime the hard drive activity can be shown also. And then, to come back I had only one option to hard re-boot.
I tried Fn+F4 and power button once to come back but no use.
Please provide me some solution for this?

Integrating SAP ECC 6.0 with Microsoft Windows 2003 Active Directory
Hi Gurus,
We are planning to integrate our SAP ECC 6.0 with Microsoft Windows 2003 Active directory.
I have several questions on this:
1. Can i authenticate all the users from SAP
2. It is used only for user authentication or can it be also used for password authentication
ie user can login using his windows password?
3. While integration in SAP does a separate table or a field is created in database.
4.If a employee leaves a company than in SAP is it possible to lock & deactivate the user automatically.
Thanks in advance.

NiharHi Mastek,
You should be able to accomodate your needs with respect to integration of your AD accounts with SAP ECC ABAP. This can be done via LDAP connector configuration. The below has info on how to perfrom the configuration at a high level. You will have to integrate, and map certain user data. You may also want to do some LDAP Connector research:

On the Java stack - you can also confugure UME to integrate/authenticate with AD:

I'm wondering if it would be possible for time machine to back-up files from 3rd party software such as Windows XP using parallel software especially if it is isolated from mac? Any advise would be greatly aprreciated.
Short answer - yes Time Machine will backup everything within the Mac OS system.
Longer answer - Parallels creates a pvm disk image "Parallels Virtual Machine" which Time Machine backs up.
Due to the changes to the pvm file Time Machine is unable to read the minor changes and will somtimes do a full backup of it each time Time Machine runs and can chew through Back up drive space quite quickly. -
I'm trying to get my itunes to go back to english but is coming up Russian on windows 7. I initally installed English version and about 6 months ago it came back Russian. It was English for over 2 yrs. I have use all the suggestion including unistall and reenstall of a new down load from apple.
I copied the iTunes file from the external drive and it's in both places. I thought all I would need is the iTunes program (which I downloaded to new computer) and my iTunes library file. There must be something else that's missing. My iTunes library looks the same on the new computer as it does when I open it on the external drive. If I click on an iTunes library song from my new computer, it will only play if I have the external drive plugged in.
My back-up drive is a mess. I have multiple copies of music, video, photo, and document files and I don't know how that happened. ={ Obviously, I don't know how to back up stuff properly and there are back-up files extending over a 6- to 8-year period. I think all I did was just drag and drop the main folders from the back-up drive to the same main folders on the C: drive. Also (and I'm kind of fuzzy on this) Windows used to automatically save music files in a folder within my document files (which makes no sense to me). As my Jewish friends would say, "Oy Vey!"
