HCL Domino Designer Basic User Guide and Reference
This guide provides information on using HCL Domino Designer and programming language reference information.
- What's new in HCL Domino Designer 12?
  The following features are new for developers in HCL Domino® Designer 12.
- Accessibility and keyboard shortcuts
  Accessibility features assist users who have a disability, such as restricted mobility or limited vision, to use information technology content successfully.
- Application Design
  Welcome to the Application Design section of Domino® Designer Help.
- Application Management
  Welcome to the Application Management section of Domino® Designer Help.
  - Security in an application
    Domino® offers a multi-layered approach to security. Server administrators can secure databases, servers, and domains. Database designers and managers control the following:
  - Completing an application and managing design changes
    As you prepare to deploy an application, consider these finishing touches:
  - Deploying an application
    The tasks involved with application design, database design, database management, and DominoTMsystem administration may overlap, depending on the size of your organization and the structure of job responsibilities. In some organizations, an application developer may be responsible for both application and database design, while in others, a database manager may handle all database design and management tasks. In addition, database management overlaps with Domino® system administration.
  - Procedure for optimizing and troubleshooting databases
    - Properties that improve database performance
      Properly setting database properties can improve the performance of an active database. Setting database performance properties on many databases or on one, large, active database can also improve server performance. In addition, some of these property settings also help reduce the size of databases.
    - To set database properties that optimize database performance
    - Controlling database size
      Databases whose size is monitored and minimized show increased performance: database operations require less I/O and fewer CPU resources; view rebuilding and updating is quicker; and memory and disk space allocation is improved. The maximum database size is 64GB on Windows™ and UNIX™. Use the following methods to regularly monitor the size of databases and minimize database size:
    - Document archiving tool
    - Monitoring replication of a database
      If there are replicas of a database, use any of these methods to monitor replication daily.
      - The database replication history
      - Viewing replication events in the log file
      - Replication or save conflicts
        Multiple users can simultaneously edit the same document in one copy of a database or edit the same document in different replicas between replication sessions. When these situations occur, Domino® stores the results of one editing session in a main document and stores the results of additional editing sessions as response documents. These response documents have the title "Replication or Save Conflict." Domino uses the $Revisions field, which tracks the date and time of each document editing session, to determine which document becomes the main document and which documents become responses.
      - Consolidating replication or save conflicts
    - Monitoring database activity
      Monitor database activity regularly. If database activity is high and users report performance problems, do any of the following:
    - Notifying users of a moved database
      After you move a database, create a new database with the same file name and path as the database before you moved it. In the new database, create a form and document that provides the following information:
    - Troubleshooting database performance
      You can reduce database performance problems by using:
    - Troubleshooting replication problems
      The following topics suggest solutions to common problems associated with scheduled replications.
- Domino® Query Language
  Domino® Query Language (DQL) is a facility running on a Domino server that provides a terse, shorthand syntax for finding documents. It supports a wide variety and complexity of search terms. It leverages existing design elements, avoiding the need to write detailed code to access them. DQL consolidates all methods in Domino for searching document contents.
- Composite Applications - Design and Management
  Composite applications are a key element in a service-oriented architecture (SOA) and contextual collaboration strategy. The ability to create and edit composite applications lets you easily integrate different types of components and technologies.
- DB2® Access views
  Domino® Designer includes two types of design elements to assist you in managing data contained in DB2® enabled Notes® databases:
- Programming Overview and User Interface
  This section contains general guidelines and examples that show where to use Java, LotusScript, and the formula language.
- Formula Language
  This section documents the formula language.
- LotusScript® Language
  Welcome to the LotusScript® Language section of Domino® Designer Help.
- LotusScript/COM/OLE Classes
- Java/CORBA Classes
  This section documents the Java/CORBA classes.
- Connectors
  Connectors provide native access to a wide variety of DBMS products, ODBC, the platform File system, Enterprise Resource Planning systems, and Transaction Processing systems.
- Javadoc™ for Domino® Designer related APIs
  As part of providing additional Java™ reference documentation, Domino® Designer ships with a help plugin that contains Javadoc™ for additional Domino Designer related APIs.

Viewing replication events in the log file

About this task

The Replication Log entries in the Replication Events view of the log file (LOG.NSF) display detailed information about the replication of specific databases. For each database that has replicated on a specified server, a Replication Log shows the access the server has to the database; the number of documents added, deleted, and modified; the size of the data exchanged; and the name of the replica that this database replicated with. The Events section of a Replication Log shows any problems that occurred when a specific database replicated. For example, the Events section shows if replication is disabled or if the database ACL is preventing replication.

To use the Domino® Administrator to view a Replication Log:

Procedure

From the Domino® Administrator, in the Server pane on the left, select the server that stores the log file you want to view. To expand the pane, click the servers icon on the left.
Click the Server - Analysis tab.
Select Notes® Log - Replication Events.
Open a recent Replication Log.

Results

Tip: If you don't have access to the Domino® Administrator, select the log file database and choose File - Application - Open.
