How can I discover what instance is the Primary Application Server?

[BrunoDuque]

Dear Community,

I'm creating a python application and I need to know on a ABAP system, what application server is the primary (also called Central Instance).

I'm able to retrieve all application servers by scanning /sapmnt/<SID>/profile but I also need which one is the PAS.

Thank you in advance for your suggestions.

Best regards,

Bruno

Hi Bruno,
By checking the profiles, you should be able to identify which is the Primary Application Server or ASCS (depending on system configuration).
Central instance will be called SID_DVEBMGS$$_hostname (where $$ stands for instance number).
In case of an ASCS, where ENQ and MS run outside, it will be called SID_ASCS$$_hostname.
The rest of the application servers are named as SID_D$$_hostname.
