Why Performance Tuning ?

• Business need for data throughput– Xbox Launch North America, Nov. ’01:

Peak volumes Existing XboxXbox ChangeSales orders / day ~ 5,000 + 7,600+ 7,600 + 152 %Deliveries / day ~ 5,000 + 11,400+ 11,400 + 228 %Sales orders / hour * ~ 250 + 2,500+ 2,500 + 1,000 %Deliveries / hour * ~ 1,000 + 2,500+ 2,500 + 250 %* Each order & delivery with 10 line items

Why Performance Tuning ?

• System availability & supportability– Prevention of:

• Cross-module increase in response time• Business disruptions• Penalties• End user frustration• Increased support costs

• System scalability– Ability to handle future growth

Project Approach

• Project team– Functional – Basis/Technical– Development– Stress Test– Consulting (BUIT & SAP)

• Project timeline– Driven by business need

• Repetitive cycle– One item at a time

• Project metrics– e.g. seconds/document

Analysis

Test

Change

TestBest Practices• Have an original baseline test• Automate tests and standardize your

data & configuration• Include anticipated new functionality

(e.g. routing, allocations)• Consider systems external to SAP• Make test as realistic as possible !

AnalysisBest Practices• Define your metrics (e.g. sec/doc,

response time, etc..)• Carefully document results and

improvements with each cycle• Review results and plan for next

changes to be implemented and tested

• Systemwide work process overview – SM66• Workload monitor – ST03• SQL trace - ST05• SQL trace interpreter - SQLR• Application analysis – ST14• Table access statistics – ST10• Memory configuration monitor – ST02• R/3 OS monitor – ST06• IDoc monitor – WE05• Gateway Monitor - SMGW• Windows PerfMon – CPU utilization

AnalysisProcess Overview - SM66

• Quick overview of all work processes• Look for:

– Long-running processes– “Stopped” processes– Highly utilized servers– Processes accessing the same tables

AnalysisDatabase Trace - ST05

• Important tool to analyze database performance problems

• Look for:– Most “expensive” database accesses

(Trace Summary)– Repetitive database accesses

ChangeBest Practices

• Changes may include:– OSS notes

(> 2,600 performance notes for 4.5B)– ABAP code optimization– Configuration – Technical settings– Hardware– Business process or logic

• Carefully document changes made

Tuning for Xbox1 – Sales Order Processing• Switch to parallel processing of

inbound IDocs Partner profile change: ’Immediate’ to

‘Background’ (via WE20) Server group configuration with resource

parameters (via RZ12) –OSS 384971 Schedule program RBDAPP01 Specify packet size and ‘Parallel’ posting option

• Deactivate IDoc syntax check• Increase of program buffer

Tuning for Xbox1 – Sales Order Processing• SD number range buffering

Table NRIV - Object RV_BELEG (via SNRO) Local buffering by work process ID Exclusion of sales orgs (OSS note 424486)

• ABAP code improvements VA01 user exits Elimination of repetitive table reads

• Table buffering Monitor access statistics (via ST10)

Tuning for Xbox2 - Backorder Rescheduling• Cleanup of old orders• Program SDV03V02 by plant – daily

Evaluation of program SDV03V01• Modification (repair) of SDV03V02

Due to SD number buffering Take order creation date & time into account

• Custom pre-processing program Dynamic job builder and distribute workload over

several processes Utilize standard SAP programs

Tuning for Xbox3 – Delivery (EDI Ship Order)• Custom pre-processing program:

Dynamic job builder and distribute workload over several processes

Utilize standard SAP program (RV50SBT1)• Additional index on table VBBE• Separation of output from document

creation Schedule RSNAST00 to process output Schedule RSEOUT00 to process IDocs and

combine into files

Tuning for Xbox3 – Delivery (EDI Ship Order)• Deactivate IDoc Syntax Check• SD number range buffering• Activate shared locking

For availability checking group level for ATP (via OVZ2)

• Evaluate program RVV50R1T (VL10) instead of current DDL Program was evaluated but not implemented Server group functionality is available in SAP

• Prevent plant locking Allow IDOC to be reprocessed (from a status 64)

instead of going into an error (status 51)• Activate ‘Late exclusive enqueue’

For material movements via OMJI (OSS 192423)• Deactivate IDoc syntax check

range of knowledge• Only test ONE change at a time• Be prepared to spend about 80% of your

time testing• And learn to hide from the Basis team
