Entering Quick Sizer

http://service.sap.com/quicksizer

Choose Start the Quick Sizer.

If you do not have a valid customer number, use 188213.

Enter a project name of your choice, for example: Sizing1

To start a new sizing, choose Create Project.

In the Tree of elements, navigate to:

SAPNetweaver -> SAPNetweaver -> Exchange Infrastructure

First Steps in Quick Sizer

Change the Peak load setting from 12:00 - 13:00 to 00:00 - 24:00.

For XI-specific help and information, choose Help.

Initial Sizing: First “guess” of 50,000 messages a day

Example: 50,000 messages of 100 KB a day, without peak

Enter:

Choose Calculate result.

Notes for XI Sizing with Quick Sizer

The size of a message is the XML size at the XI server outboundchannel. Example: IDoc-XML size, message size after dataenrichment.

The number of messages is the number of outgoing messages. Example: If you send 100 messages to 3 receivers, the number of messages is 300 messages.

Weekly, monthly, annual, and single initial load peaks cannot bemodeled directly in XI Quick Sizer. They must be included in thetotal amount.

Exercise 1: Quick Sizer (30 Minutes)

Calculate the required number of SAPS and define the peak hour(s).

http://service.sap.com/quicksizer -> Quick Sizer

Create project Group<xy> with customer number 188213, where <xy> isyour group number.

Scenario data:

1. File -> IDoc, 20,000 messages of 120 KB a day

2. IDoc -> JMS, JDBC, and IDoc, 3,000 messages/hr of 100 KB between06:00 and 09:00

3. SOAP <-> JDBC, 500 messages of 20 KB between 08:00 and 18:00

All scenarios include content-based routing and Java mapping

No scenario works with acknowledgments

Exercise 2: Find Hardware for SAPS Numbers

Find hardware (from vendor of your choice) for 3,000 SAPS.

Itemfield Conversion Agent Sizing

If you use Itemfield Conversion Agent, additional SAPS are requiredto process the transformations.

Below are the SAPS requirements for Excel, PDF, HL7, and HL7 Serializer transformations:http://help.sap.com/ -> Documentation -> SAP NetWeaver -> SAP NetWeaver 2004 -> Process Integration -> SAP Exchange Infrastructure -> Runtime -> Connectivity -> Conversion Agent -> Conversion Agent Operations Manual -> Chapter: Sizing

TRex Sizing for Indexing XI Messages

Quick Sizer for TRex calculates using the number of competing dialog users. Quick Sizer gives no numbers for the indexing of documents, which is XI’s main use of TRex.

To estimate the SAPS for the XI usage case, use the sizing document.

http://trex:1080 -> Documentation -> 6.1 -> Sizing -> Point 2.2.2

TRex Sizing for Indexing XI Messages: Example

Example:100,000 messagesWithin 24 hours Average message size: 100 KB

Volume calculation: 100,000 messages * 100 KB ~ 10 GB of data

Find SAPS in table: Row “24 hrs” and column “10 GB”

Result = 500 SAPS for TRex indexing hardware with 2.5 GB RAM

Important: This is just a short example. For more information, read the whole TRex sizing document.

Message Sizes

First Estimation

Message Size on the Integration Server

Mesage Size in the Runtime Workbench

Page 18: Quick Sizing Exchange Infrastructure 3.0 - Webinar Power Point

Collect Relevant Sizing Data

Rule of thumb:

If all you know is the average message volume per day:

Number of expected messages per day

with average message size of 100 KB per message

with no peaks in 24 hours

As the first estimation!

Find Message Size on the Integration Server

To find your message, call transaction SXMB_MONI and chooseRunTime in the Call Adapter folder.

The total message size is displayed, and on the next line the messagepayload size.

“Good” Message Sizes

Throughput example:

Rules of thumb for high throughput:

Avoid small messages (less than 100KB)

Avoid large messages (greater than 2MB)

Get Larger Messages from Adapters/Applications

Collect single messages of the same type and send together.

Use packages where possible.

“Append Files” and send together.

Quicksizing Limitations

No information on resource distribution for ABAP or J2EE

Based on assumptions

Tends to “oversize”

Ongoing evaluation as project develops:

1. Implement main or typical customer scenario

2. Measure it with RWB Performance Monitoring

3. Optimize settings

4. Recalculate overall SAPS demand
