Cleaning up Old systems or marking obsolete after upgrade

Hello there,

We have 80+ systems in our landscape. We have SAP R3 4.7 Enterprise to ECC 6.0 installations. We have BW systems. We have PI systems....

We just went through an upgrade of our oldest system that was 4.6C. We had manually placed these systems in the SLD. I have deleted the old 4.6C systems from the SLD but how to clean these systems out of Solution Manager? The SLD fed this system information to our Solution Manager so I can not update the system in SMSY because it is marked as the Source being SLD.

This system was in a Logical component and in Projects.

I see in the gateway logs that Solution Manager is still trying to talk to this system. How can I stop all the obsolete systems that we want to keep for documentation purposes in the projects and in the old logical components but tell Solution Manager not to monitor or try to get information from this system.

We have other instance where we bring up and sandbox and now the sandbox is gone.... so we are accumulating quite a mess in solution manager with out knowing a way to retire a system.

Thanks for your assistance.

    Hello Deidre,

    In SMSY, the data source is the last data source used. This is a status and not where it is changed.

    The SLD will update SMSY when the job landscape_fetch runs.

    So if you removed the systems from the SLD, then when you delete them from SMSY they should not be recreated.

    The systems must be physically retired, because if they remain up and on the network, they will continue to use the SM_<SID>CLNT<#>_BACK RFC.

    If the systems are removed from SMSY, they should also be removed from the logicals, and projects. A logical can exist without a system assigned, but if that logical is in use, and has a retired system assigned, you will see activity when the logical is used, or checked by the system when that logocal is referenced.

    So you need to remove the system from the logicals and the project. I don't know how ii might then affect your projects as a reference system. But then should you be using a productive system for this purpose? You can de-activate a logical in SMSY. Maybe that might help stop its use. The same would apply to projects, the system would have to be removed from any assignments.

    Do you have a sandbox/test system where you could keep the old reference projects so you can properly define your system landscape? Really what you are doing by just pulling out the systems in SMSY is creating an incomplete configuration.

    Regards,

    Paul

    • Thanks for everything. That was very helpful to delete the SM* connections in SM59 on Solution Manager.

      It helps with the gateway errors but not on the solution of how to properly add and DELETE systems from an landscape during upgrades...etc...

      thanks
