Hetero. sys copy between Windows and Linux

[Former Member]

We are moving our system from Windows (app and database) to a new configuration (new windows box for the application and Linux, on another box, for the database). Is heterogeneous copy the way to go? There seems to be little specific info regarding Linux. Can a heterogeneous copy split a one server system into a two box system?

Hi Rich,

Yes you can do this easy, you need to do an export and then make an import for distributed systems you can follow this note: 1148109

Rich ,

It is possible and you have to use heterogeneous system copy method. Here is the brief steps :

1) Using SAP installer (SAPINST) and perform an export on the source system. Use system copy --> source system -- Central instance. Do not use DB specific tool during tool selection option in SAPINST.

2) Build your Target Linux system for database ( install OS, create file system and all users and groups ) and Windows system for CI

3) Copy or FTP your export from steps-1 to Linux environmnet as well as Windown system.

4) On the Target Windows system : using SAPINST system copy -- target system -- Distributed system option install your "globalhost". In case Java stack - this is called SCS. use the following options  for SAPINST

5) On the Linux host : Install DB software. Use SAPINST to build your DB instance and perform import. ( Please note that you have to use Database Instance build option under Distributed option.

6) On the Windows host : User SAPINST - Distributed option and build CI.

7) perform all post task,

Good luck.

Hi,

main points which you need to take care during export is about Endian  and as far as i know linux is little Endian.

While importing please select distributed system environment as mentioned by Dipam where you have to do global host preparation on one host and then do database import on other host (CI and ASCS on one host and DB on other host). CI installation will be done on same host where you have done GHP.

Kind regards,

Endianess is platform dependent not OS dependent (only indirectly). Linux x86  is little endian, Linux for Power is big endian.

Hi Rich,

Yes. You need to use Distributed method, where your CI and DB is splitted. Please download the system copy and installation guide for better overwiew. Do let us know if you have further question.
