Logical System Name after System Copy

[Former Member]

Hello,

I have three questions about the logical system name after system copy.

Q1) When I change SID D22 to S11 during system copy,

do I have to change the logical system name of all clients in the target system? The target system is used for test, and the landscape has S11 and Virtial system. The target system S11 does not communicate with the source system D22.

Q2) If the answer for Q1 is YES, is it correct that the following procedure for changing logical system name?

1.Tr-CD:BD54

Add new logical system name for all clients in the target system.

2.Tr-CD:SCC4

As for all clients, select new logical system name with F4 help.

Q3) If the answer for Q1 is YES, do I have to add new RFC connection entries with SM59 for all clients in the target system?

I refer to the guide "Homogeneous and Heterogeneous

System Copy for SAP Systems Based

on SAP Web Application Server

ABAP 6.40 SR1".

thanks,

Hi Keishi,

As a good and ideal practice the answer to your first question Q1 is yes. Infact I would say that in case you are using ALE then it is must

For Q2 there has to be an additional step which is most important one. Running BDLS transaction which would allow you to change logical systems in relevant tables from the one of source system to target system.

For Q3 the answer is agaain yes and you can have two approaches>

1. manually recreate all the RFC destinations after sys. copy.

2. Export all the RFC destination data relevant tables before system copy and then reimport them after sys. copy.

Hi Ruchit,

Thank you for your helpful answer.

I try BDLS transaction and recreate RFC destination manually.
