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.
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.
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.
Viewing a document Archiving Log
If you set up the document archiving tool to log archiving information to an Archiving Log database, a document is created in the Archiving Log database when either the client or server finishes archiving. You can view this document.

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.
- 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.
  - 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.
    - Running the document archiving tool
      If you selected the option Automatically on server, run the Compact task on the server that stores the source database.
    - Viewing a document Archiving Log
      If you set up the document archiving tool to log archiving information to an Archiving Log database, a document is created in the Archiving Log database when either the client or server finishes archiving. You can view this document.
    - Using an agent to delete and archive documents
      Agents give you a very high degree of control over document deletion criteria. However, agents can be slow to run.
    - Examples of using an agent to delete and archive documents
      You can use an agent to delete and archive documents.
  - Allowing more fields in a database
    You can increase the number of fields allowed in a database by selecting the advanced database property Allow more fields in database.
- 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.

Viewing a document Archiving Log

If you set up the document archiving tool to log archiving information to an Archiving Log database, a document is created in the Archiving Log database when either the client or server finishes archiving. You can view this document.

About this task

Procedure

Open the entry in the Archiving Log database.
Click Archive statistics to display the date of the archive, the number of documents archived to the Archive database, and the number of archived documents deleted from the original database.
Click Database/Server to display the location, title, and path for the original database and for the Archive database.
Click Links to archived docs to use document links to access documents in the Archive database that have been removed from the original database. This doesn't apply if you selected the advanced archiving option Delete matching documents without archiving them.
