SAP ERP 6.0 EHP7 upgrade optimal resources
I am performing EHP7 up gradation on SAP ERP 6.0.
SYSTEM H/W: 8 CPU's 50 GB RAM
OS : windows server 2008 R2
DB: oracle 22.214.171.124.0
SAP source release : ERP 6.0
SAP target release : ERP 6.0 including EHP 7
I have performed above said activity on test system / development system / quality system /production system. The time to complete different systems varied beyond my expected/planned values.
I understood that there are users logged into production system till pre processing stage of SUM tool.So the long running phases (ACT_UPG , SHADOW_IMPORT , etc ) took approximately double the time than other systems.
May i know various other other reasons ,for productions system , which reduces performance (in terms of run time).Is there any ways to improve performance (in terms of run time) .
I have increased R3trans processes,Batch process to higher values during configuration phase of SUM tool.What are the optimal values which can be given in for fast upgrade.
thanks & regards
