IBM® Domino 10.0.1 Documentation
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.
  - 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.
    - Setting database properties that optimize database performance
      You can set database properties to optimize database performance and to reduce database size. Set database performance properties by opening the Database Properties box on an existing database or as you create a database.
    - Enable soft deletions
      In some databases, deleting a document permanently removes it from the database. In other databases, such as the Notes® mail file database, deleting a document moves it into a Trash folder and stores it in a state of "soft deletion." From this folder, users can restore deleted documents by selecting Restore.
    - Using database design compression
      Use the advanced database property Compress database design to reduce the total cost of ownership of maintaining any Notes® database by reducing the size of all design elements in the database.
    - Using document body compression
      Use the advanced database property Compress document data to reduce the total cost of ownership of maintaining any Notes® database by compressing non-summary item data in all documents in a selected database. Document compression can provide up to a sixty percent size saving.
    - The database cache
      To minimize delays that occur when users, servers, or API programs open and close databases on a server, each server maintains a database cache. When a database closes and there are no users or processes using the database, Domino® puts the database in the cache so it can close it quickly. The database remains in the cache until it's opened again or for about 15 to 20 minutes, whichever comes first. Databases in the cache can be opened quickly.
    - Tools for monitoring database size
      This table summarizes the methods you can use to monitor database size and the information each method provides.
    - Monitoring database size
      You can monitor size and used space in a database.
    - Compacting databases
      When documents and attachments are deleted from a database, Domino® tries to reuse the unused space, rather than immediately reduce the file size. Sometimes Domino will not be able to reuse the space or, because of fragmentation, cannot reuse the space effectively until you compact the database.
    - Determining the file format of a database
      You can check the ODS (on-disk structure) and determine the file formats of databases before compacting them.
    - Compact options
      This topic describes options you can use with the Compact server task.
      - Running Compact using the Files tab
        Use the Compact tool in the Files tab of the Domino® Administrator to run Compact on specific databases. The databases can be stored on a server or stored locally on a Domino Administrator client.
      - Running Compact using the Task - Start tool
        Use this method to compact many databases on a server. You can continue using the Domino® Administrator during compacting.
      - Running Compact using a console command
        You can compact from the console.
      - Running Compact using a Program document
        Use a Program document to schedule Compact to run at a regular time. For example, schedule Compact to run with the -B option once a week.
    - Database size quotas
      Set a database size quota to specify the maximum size a database can attain.
    - Deleting inactive documents
      Regularly delete inactive documents from databases to save disk space, to make it easier for users to find information, and to improve database performance.
    - Allowing more fields in a database
      You can increase the number of fields in a database by selecting the advanced database property Allow more fields in database which allows the database to contain up to 23,000 fields.
  - 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.

Running Compact using a console command

You can compact from the console.

Procedure

From the Domino Administrator, on the Server (first) pane, select the server on which to run Compact. To expand the pane, click the servers icon.
Click the Server - Status tab.
Click Console.
Enter the following command in one of the following ways: 1) in the command line at the end of the console, and then press ENTER or 2) directly at the console on a server:
```
Load compact databasepath
options
```
where databasepath specifies the files to compact

and options are Compact command-line options.

Example

The following table illustrates how you can use databasepath to specify databases, folders, and subfolders.

Table 1. `databasepath` examples
To compact	Example command	Files compacted
A specific database in the Domino® data folder	Load compact SALES.NSF	DATA\SALES.NSF
All the databases in a folder relative to the Domino® data folder	Load compact SALES	DATA\SALES\all databases
A specific database in a folder relative to the Domino® data folder	Load compact SALES\USER1.NSF	DATA\SALES\USER1.NSF
All the files specified in a .IND file created in the Domino® data folder Note: If you are using the -T flag to specify a view, Indirect files (.IND) cannot be used.	Load compact WEEKLY.IND where WEEKLY.IND contains: SALES.NSF DEV.NSF SALES\USER1.NSF SALES\NEW	DATA\SALES.NSF DATA\DEV.NSF DATA\SALES\USER1.NSF DATA\SALES\NEW\all databases
