The Sametime® workloads

The Domino® Administrator client contains three IBM® Sametime® workloads.

About this task

  • Sametime® Initialization workload
  • Sametime® 7.0 Instant Messaging workload
  • Sametime® 7.5 Instant Messaging workload

The information in this topic applies to all three Sametime® workloads. Review this section and complete the necessary steps prior to running any of the three Sametime® workloads.

Sametime® Workload Setup

Procedure

  1. Install the Domino® Administrator client. Select the Server.Load option from the Client Install Options list.
  2. Install Server.Load or NotesBench into the Notes® client program directory as needed.
  3. Add the required NOTES.INI settings to the test driver's NOTES.INI file and replace the values in the table with the values for your test setup.

NOTES.INI variables required by all Sametime® workloads

About this task

In the examples, RND(XdY) indicates that a random number is generated by rolling a "Y" sided die "X" times. For example, RND(5d10) indicates that five 10-sided dice are rolled and the results are summarized to form a random number.

Table 1. NOTES.INI variables

NOTES.INI variables required by all Sametime® workloads

Description

NB_EnableSTAwareness=1

Prefix for users; for example, "mail"

ST.password=<user password>

Password used to authenticate a user

ST.login.type=[MUX|JAVA]

MUX simulates a mux, JAVA simulates a direct client connection

ST.logout.pause.wait=RND(100d6)

ST.test.maxusers=10000

Maximum number of users in the test

ST.debug.filename=c:\\results\\debugout.txt

The name of the file to which errors are written, requires STdebug > 0

STDebugOn=<value>

Specify one of these debug settings:

  • STDebugOn=0 -- Debug information is not sent to the console.
  • STDebugOn= <a positive number> -- Debug information is sent to the console.

NB_Include_ST_Stats=1

Enables per-minute statistics to be sent to the console window. To capture the stats, set DEBUG_OUTFILE=<filename>

Table 2. Variables required for Sametime® 7.0 and 7.5 Instant Messaging workloads

NOTES.INI variables for the Sametime® 7.0 and 7.5 Instant Messaging workloads

Description

ST.converse.pause.wait=RND(10d6)

Think time between exchanged messages

ST.converse.nummessages.quan=RND(1d10)

Number of messages per chat

ST.converse.messagelength.quan=RND(8d128)

Size in bytes of each message sent

ContextIteration1=3

Run a command every third iteration (once every 45 minutes)

ContextIteration2=24

Run a command every twenty-fourth iteration (once every 6 hours)

ContextIteration3=12

Run a command every twelfth iteration (once every 3 hours)
Table 3. Variables required for the Sametime® 7.5 Instant Messaging workload

NOTES.INI variables for the Sametime® 7.5 Instant Messaging workload

Description

NB_ENABLELOCATIONWATCH=1

Choose one:

  • 1 -- To enable buddy list watching for the location
  • 0 -- To disable buddy list watching for the location

ContextIteration4=12

Run a command every twelfth iteration (once every 3 hours)

ST.converse.htmltext.percent=90

Percent of all rich text messages sent with STchat that should be HTML

ST.converse.img.percent=10

Percent of all rich text messages sent with STchat that should be images

ST.converse.img.filename=c:\\lotus\\notes\\data\\image.gif

The image file that users should send. The maximum image size is 100K.

NB_DISABLEFILETRANS=1

Note: In tests, file transfers have been shown to be resource-heavy operations. To save resources, IBM® recommends setting NB_DISABLEFILETRANS=1. If file transfers are required, set NB_DISABLEFILETRANS=0.

To run the workload with File Transfer enabled, set this variable to 0.

NB_STFTransSizeInBytes=1000000

Size (in bytes) of the file to transfer. Server policies can restrict this on the server side

NB_STFTransFileTypeBinary=1

Set to 1 for binary format, otherwise it is set to text

ST.ft.send.file=<filepath/name

Specify a particular file for file transfer

ContextIteration5=24

Associated with File Transfer in the workload. In this example, the 24 indicates that file transfer will occur once every 24th iteration.

ST.ft.receive.location=<path>

Where to place the received file on file transfer. Currently the file is deleted after it is received, but a valid location is necessary
