- 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.

  - 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.
    - 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.

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:

Title of the original database
File name and path of the original database
Date of the move
Reason for the move
Server currently storing the database
New file name and path of the database

When users open this database, they'll see information about the new location.

Adding a button to open a database

In addition to including information about the database move in the form, you can create and program a button that users click to automatically add and open the database at its new location.

For example, this button formula adds a database with the replica ID 84254E66:0064508 to the workspace and then opens the database:

@Command([FileOpenDBRepID];"84254E66:0064508"; "SALES")

The last argument, "SALES," provides the name of the server on which the database is located.
