Tuning
Use this information to improve HCL Domino® server, Domino Web server, and messaging performance through the use of resource balancing and activity trends, Server.Load commands, advanced database properties, cluster statistics, and the Server Health Monitor.
- Resource balancing and activity trends
  Domino® server resource utilization can be separated into two types, system activity and user activity. System activity, which includes the level of processor, disk, memory, and network consumption that Domino generates to keep the server running, is a fixed amount of activity, as long as systems are healthy and performing smoothly. Domino servers typically use a modest percentage of their resources to run. The remaining server capacity is used to support user activity, which varies with the usefulness of the data on the server.
- The Server.Load tool
  Server.Load is a capacity-planning tool that you use to run tests, also called "scripts" and "workloads," against a targeted Domino® server to measure server capacity and response metrics.
  - Server.Load agents
    Server.Load includes a set of agents in the file NAMAGENT.NSF, which is initially installed in the data directory on the Domino® Administrator client. The first agent in this list -- Create NotesBench Mail Person Documents -- is used to set up Person documents for the workloads and set the HTTP password. The rest of the agents are used to repair and change the workload setup.
  - Server.Load metrics and messaging statistics
    As you run a test, you can view various script metrics and server statistic metrics and optionally store the test output in a separate file. Server statistic metrics are generated by the Domino® server. Script metrics correspond to Server.Load command names and display the performance of particular commands. For example, if you select the Add metric, the Metrics window displays the results of the Add command.
  - Setting up clients and servers for Server.Load
    To use Server.Load, install the Domino® server on the server under test (SUT) and install the Domino Administration client and the Server Load Utility on each client.
  - Built-in and custom Server.Load scripts
    Server.Load includes a set of built-in scripts. You can also create a custom script from scratch.
  - Running the built-in Server.Load workloads
    Server.Load contains numerous built-in workloads and initialization workloads.
    - Cluster Mail Initialization workload
      The Cluster Mail Initialization workload creates a mail database on the server and populates the mail database with a number of notes scaled to the SUT.
    - Cluster Mail workload and test preparation
      The Cluster Mail workload executes Notes® transactions that model a cluster for mail users at sites relying on a two-way Domino® cluster for messaging.
    - DWA85 workload
      The DWA85 workload represents an active iNotes® user in Full Mode sending, retrieving, and deleting mail from a browser.
    - DWA85Lite workload
      The DWA85Lite workload represents an active iNotes® user in Lite Mode sending, retrieving, and deleting mail from a browser.
    - DWA85 Initialization workload
      The DWA85 Initialization workload creates a set of mail databases on the server and populates them with mail. The mail databases are populated with the number of notes (messages) specified in the NOTES.INI variable NumMailNotesPerUser. When you set NB_MailRealFromField=1, the mail messages appear to be from other valid users. Next, the workload sets the preferences, reads five messages from the newly populated inbox, and replies to all five by setting a random name as the sender from the range of valid users in the Domino® Directory.
    - R5IMAP Initialization workload
      The R5IMAP Initialization workload creates and populates the IMAP mail file with SMTP messages, initializes the mail file, and then converts it to IMAP.
    - R5IMAP workload
      The R5IMAP workload models an active IMAP mail user logging in once, then receiving and sending mail. The script contains an average of 15 minutes of waiting, so an average user will execute this test no more than four times an hour. For each iteration of the script, IMAP mail messages are retrieved, one SMTP message is sent, and a number of LDAP lookup requests are executed based on the value of the NumMessageRecipients script variable. The SMTP messages sent by each test user are delivered to the mail databases of other test users on the SUT.
    - R6IMAP Initialization workload
      The R6IMAP Initialization workload opens a mail database on the server and populates the mail database. The template that is used to create the mail databases should be specified in the NOTES.INI variable MailTemplate.
    - R6IMAP workload
      The R6IMAP workload executes Domino® transactions that model a server for mail users at sites that rely on IMAP mail for communication. Not only does this test stress the IMAP protocol by receiving mail messages, but also exercises SMTP and LDAP by sending SMTP messages to a number of recipients and performing LDAP lookups on those recipients.
    - iNotes® Initialization workload
      The iNotes® Initialization workload creates a set of mail databases on the server and populates them with mail. The mail databases are populated with the number of notes (messages) specified in the NOTES.INI variable NumMailNotesPerUser.
    - R5iNotes workload
      iNotes® is the Web client for Web-based access to Domino® messaging and Personal Information Management (PIM) capabilities.
    - R6iNotes workload
      iNotes® is the Web client for Web-based access to Domino® messaging and Personal Information Management (PIM) capabilities.
    - NRPC Mail Initialization workload
      Use the NRPC Mail Initialization workload to prepare for the R5 Simple Mail Routing workload and the R6 Mail Routing workload. The NRPC Mail Initialization workload creates the mail databases for the R5 Simple Mail Routing workload and the R6 Mail Routing workload.
    - R5 Simple Mail Routing workload
      The R5 Simple Mail Routing workload models an active Notes® mail user receiving and sending mail, composing and sending meeting invitations, and scheduling appointments. The script contains an average of 15 minutes of waiting; therefore, an average user runs this test no more than four times an hour.
    - R6 Mail Routing workload
      The R6Mail Routing workload models an active user on a client reading and sending mail, using the calendar and scheduling features to schedule an appointment, send an invitation, and send an RSVP to an invitation.
    - N8Mail Initialization workload
      Use the N8Mail Initialization workload to prepare for the N8Mail workload and the N7Mail workload. This workload creates the mail databases needed to run both workloads.
    - N8Mail and N7Mail workloads
      The N8Mail and N7Mail workloads model an active user on a Notes® 8 client and Notes 7 client respectively, acting on a Domino® 8 server performing the same set of calendaring and mail operations. An average user will run this script four times per hour.
    - SMTP and POP3 Initialization workload
    - SMTP and POP3 workload
      The SMTP and POP3 workload models an active user receiving and sending mail over SMTP and POP3. The script contains an average of 10 minutes of waiting, so an average user will run this test no more than six times an hour.
    - The Sametime® workloads
      The Domino® Administrator client contains three HCL Sametime® workloads.
      - Sametime® 7.0 Initialization workload
        The HCL Sametime® 7.0 Initialization workload populates the buddy list storage database (VPUSERINFO.NSF) on the server for each test user.
      - Sametime® 7.0 Instant Messaging Workload
        The HCL Sametime® 7.0 Instant Messaging workload models an activeSametime user who will login, chat, change status, act on the buddy list, and logout.
      - Sametime® 7.5 Instant Messaging workload
        The Sametime® 7.5 IM Workload models an active HCL Sametime user who logs in, queries policy information, queries user info, watches the locations of buddies, chats using rich text, changes status, acts on the buddy list, and logs out.
    - Idle workload
      The Idle workload establishes the highest number of sessions that a Domino® server can support. The test establishes sessions only between a client and server; no Notes® transactions are carried out. No resources other than those required to start a session are used.
    - R5 Shared Database workload
      The R5 Shared Database workload models active users performing shared database operations that include performing view operations, navigating unread documents, reading documents, and adding or updating documents in a shared database.
    - Web Idle workload
      The Web Idle workload models a Web browser user accessing the home page on the SUT. The script contains a one-minute wait, so an average user runs this script approximately 60 times an hour.
    - Web Mail Initialization workload
      This topic describes testing the Web Mail Initialization workload.
    - Web Mail workload
      The Web Mail workload models an active Web Mail user using a browser to send, retrieve, and delete Notes® mail.
    - Workload Data Collection and Workload Data Rollup scripts
      The Server.Load Workload Data Rollup feature is adapted from the NotesBench data rollup feature and allows test data from a group of test drivers and an SUT to be combined into a single data file for analysis. While a workload runs, the Workload Data Collection custom script, SHSTAT.SCR, collects performance data from the SUT. When the workload is complete, the Workload Data Rollup script rolls up the performance data.
  - Server.Load commands
    Server.Load scripts consist of statements in a simple command language, the Server.Load specification language.
  - Server.Load scripts
    You can use any of the sample Server.Load scripts as they are or you can use them as a basis for creating customized scripts.
  - How Server.Load determines the range of mail addresses it uses when sending messages
    Server.Load uses the logic described in this topic when determining the range of mailing address to be used.
- Tuning Domain Indexer performance
  Each time the Domain Indexer task runs, it looks in the Domain Catalog for new databases that have the Include in multi database indexing property enabled. It then looks for documents and files in existing databases and file systems that are new or changed since the last time it ran, and adds them to the Domain Index.
- Improving Domino® server performance
  Read the following topics for help on improving basic Domino® server performance and capacity, as well as the performance of these features: Agent Manager, databases and the Domino directory, the directory catalog, LDAP searches, mail, Web server, and UNIX™ server.
- Improving Web server performance
  After you set up the Domino® Web server and make sure that it runs properly, check the server's performance and response time.
- Improving mail performance
  Domino® includes features that improve efficiency in specific environments, but these features may not be switched on by default.
- Setting advanced database properties
  Advanced database properties include performance optimization and compression features, as well as ways to manage usability features such as unread marks and soft deletions.
- Understanding cluster statistics
  Three categories of Domino® cluster statistics help you analyze clusters
- Improving the performance of the Server Health Monitor
  If the Domino® Administration client workstation performs at 100 percent CPU utilization for a long period of time, the Server Health Monitor discards server statistic data to keep up with the workload.

Sametime® 7.0 Initialization workload

The HCL Sametime® 7.0 Initialization workload populates the buddy list storage database (VPUSERINFO.NSF) on the server for each test user.

About this task

The limitation for the workload is the total population divided into groups of "N" users, where "N" is the number of users initialized on a particular driver. The values for the NOTES.INI settings ST.bl.beginuser.number and ST.bl.enduser.number will vary accordingly on each client driver, for example, 1-1000,1001-2000, etc.

ST70Init Workload considerations are as follows:

Pause 4-16 minutes
Log in
Pause 2-8 minutes
Initialize the Buddy list by using the following NOTES.INI variables:
- ST.bl.size.quan= -- The number of users to add to each buddy list
- ST.bl.beginuser.number= -- The starting mail* number for adding to the buddy list
- ST.bl.enduser.number= -- The ending mail* number for adding to the buddy list
Log Out

All of the NOTES.INI variables required by the Sametime® workloads are detailed in the topic, The Sametime® Workloads.

Running the ST70Init workload from the Server.Load utility

Procedure

Start Server.Load.
In the field, Select Script, choose Sametime Initialization Workload, and then click Execute.
Click Start Test.
Proceed to one of the Sametime® workloads according to which one you want to run.
Optional: To verify that the workload has run correctly, use the Sametime® Connect client to log in as any of the initialized users to verify that the user has a populated buddy list.
