Welcome to the IBM® Domino 10.0.1 Administrator Help.
- What's new in IBM® Domino® 10?
  Learn about all of the new features for administrators in IBM® Domino® 10.
- Overview
  Welcome to IBM® Domino® Administrator Help.
- Installing
  Use this documentation to install the IBM® Domino® server and subsequently deploy the IBM Notes® client.
- Planning
  Use this topic as an overview of planning task.
- Configuring
  Use this information to configure an IBM® Domino® network, users, servers (including Web servers), directory services, security, messaging, widgets and live text, and server clusters. Also use this information to set up IBM iNotes® on a server using Domino Off-Line Services (DOLS).
- Securing
  This section describes IBM® Domino® security features, including execution control lists, IDs, and SSL.
- Administering
  This documentation provides information about the administration tools for managing and monitoring IBM Domino® servers and databases.
- Tuning
  Use this information to improve IBM® 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.
    - 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.
- Troubleshooting
  This section describes how to find and solve problems with IBM® Domino® server and Administrator client.

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 supports any platform that is supported by the Domino® Administrator client. The client runs the Server.Load tests and generates the transactions that are presented to the server. A typical Server.Load configuration has one or more client systems driving the server under test (SUT). Each client running Server.Load generates a simulated user load of Notes® transactions against the SUT, which reports server statistics back to the client. If you configure multiple clients, you set up and run the test from each client system.

You can run built-in scripts, create custom scripts from a library of commands, or submit commands manually. For example, run the built-in R5 Simple Mail Routing script to simulate users on an Notes® client reading and sending mail. Or create a custom script to create and open a Notes® mail database and populate it with messages. To test or execute individual commands, you can use the manual command line mode to delete documents from a database or issue remote server commands.

CAUTION: Server.Load and the Notes® client should not run concurrently on the same machine.

Using Server.Load, you have real-time control of the test environment and variables. Prior to running a test, you can change test parameters, stop conditions, and existing script variables. You can also monitor real-time server metrics. While the script is running, the Metrics window displays an immediate characterization of server performance by updating metrics on a per-minute basis.
