Dear SAP gurus,

I need to perform system refresh using database load method ( using sapinst- export from source, and import into target system). Target system is running at this moment with oracle DB and wanted to refresh this using source.

Could you please tell us what are the steps to be taken in the target system before starting the import into the target system.

do i need to uninstall the target system completely? or is it fine if i delete only datafiles and start the import option using sapinst. Requesting you to please let me know how the sapinst detects the existing oracle DB software and fills the data with the source DB export.

Thanks and Regards

Hi Purna,

Downlaod the system copy guide and follow the steps.For export/import you have to do the preparation on the source system and export the database.Uninstall sap completely from the target system and perform the import using sapinst.

Hi,

When you go for ABAP+JAVA system refresh .

Take the JAVA export of the source system with the help of sapinst.Check the j2ee_admin and the ddic(000) password of source system before the export.

then you need to get the offline backup of the Source system.

then import it on the target system wth the help of sapinst and in the middle it shall promt you to restore from the backup of the source system.Please restore the offline backup of the source system on the target system.

Then it shall promt you the message thet which all scema you want to drop.Drop the scema of the source system only.

Then it shall ask you the export directory.

Dear Rishi,

Thanks for your quick response.

My case here is not ABAP+JAVA system, I need to do the ABAP only system refresh.

source is at 32 bit , and my target is at 64 bit. because of this It is needed to perform the system refresh using sapinst method.

my doubt here is do i need to only delete the datafiles in the target system and proceed further?

or do i need to uninstall the system and make a fresh system using the sorce exported data.

Thanks and Regards

if you have only ABAP system then go with the option of ABAP ystem option in the sapinst.

source is at 32 bit , and my target is at 64 bit.

But as you said thet your source is 32 bit and the target is 64 bit you need to get the hardware that is 32 bit so thet the target can have the same server bit sa the source.

Please get the target server also 32 bit.

Dear Ashok,

Thanks for your replies.

Do i need to uninstall oracle DB software also along with the system?

@ Dear Rishi,

My requirement is that i need to do system refresh using source 32 bit and target 64 bit. that is the reason i have opted the sapinst (R3load) option, otherwise i would have gone to backup -restore method.

Let me explain you .

All the executabke thet you have in you 32 bit system will not run on a machine will not run on the 64 bit so you need to do migration .

Dear Rishi,

This is the reason we may need to uninstall the system and do fresh installation using sapinst and dataload using source exported data as Ashok previously mentioned.

at the time when we do install the system , we need to give 64 bit kernel along with oracle client software.
