SUM -DMO queries

[former_member201054]

Hi Experts,

a) How to make the SUM tool to run DMO only ?- for performing database migration to HANA 2.0.

b) for running DMO...Should we need to create this file SAPup_add.par and set parameter migration_only=1 ?

c) How to determine the SUM tool version either 1.0 or 2.0 for using DMO?

d) for doing any database migration with DMO-SUM tool..Should we still need to generate the DDL statements using SMIGR_CREATE_DDL in the source system?

Source database : DB2

e) If I want to change the app server CI - Should I select system move in DMO ?

f) List out the heterogenous specific log files for troubleshooting in DMO

Please answer all these queries exactly.

I would appreciate your help..

Thanks in advance

Hi Daniel,

your starting point is Software Logistics Toolset (sap.com) for SUM guides and information.

a) This is explained step by step in the SUM guide "Performing DMO Without System Update". When running SUM you choose the scenario without stack.xml file. Alternatively check SAP Note 2444717.

b) No!

c) Check Software Logistics Toolset (sap.com):

• SUM 1.0 for Java stack, dual-stack, and ABAP stack (ABAP with target versions below 7.50)
• SUM 2.0 for pure ABAP stack and target versions based on 7.50 and above

d) This is not necessary. SUM will do this.

e) If you want to move of the primary application server from source to target system, then yes! Please also check the blog post of boris.rubarth : DMO with System Move – the use case to change PAS host during DMO | SAP Blogs

f) This depends on the phase you are in. Always check the SAPupConsole.log file and the corresponding application specific log. Basically the logs having something with "MIGRATE" or "MIGRATION" in the name are of interest. For DMO performance please check the blog post of stefan.mueller2: Optimizing DMO Performance | SAP Blogs
