Can we get rid of AppHost DVEBMGS00 in a distributed system?

[former_member297435]

Currently we have a ECC 5.0 Distributed system. We have resource constraints on AIX hardware and need to either migrate this server from AIX to Linux or if possible just turn it off and get rid of the instance. Can we just turn off App Server Host 1? Is it required for any reason? We can add as many App servers as needed on Linux, no resources constraints on the Linux hardware.

Current configuration

DB Cluster DBHost1 and DBHost2: (AIX) ASCS00 Oracle DB

App Server Host1: (AIX) DVEBMGS00 (Only running dw processes - gw, ms etc is on the ASCS00 DB Host)

App Server Host2: (LINUX) D10

App Server Host3: (LINUX) D20

App Server Host4: (LINUX) D30

App Server Host5: (LINUX) D40

App Server Host6: (LINUX) D50

App Server Host7: (LINUX) D60

App Server Host8: (LINUX) D70

App Server Host9: (LINUX) D80

Hello,

Since you have an ASCS instance, the DVEBMGSxx instance is "technically the same" as any Dxx instance.

However, an SAP upgrade process (e.g., from ECC5 to ECC6) must be executed at the "PAS" (Primary Application Server), which is the DVEBMGSxx instance.

I do not have the "low level details" of why the DVEBMGSxx is required (maybe for compatibility reasons, so the upgrade can run in any scenario - with or without ASCS, distributed installation or not, ...).

You would have to migrate it, if you want to disable your AIX server.
