1.2.9 Master and Slave System Configurations

Visual LANSA uses a database management system to store the local or Slave LANSA Repository. This section defines the supported database configurations for developing with the Master and Slave systems.

Supported Configurations

A separate Visual LANSA database must be used for each LANSA system on the IBM i. The database may be a workstation (single user) or a server (multi-user) database. Just one Visual LANSA database should be used for one LANSA Repository on the IBM i.

In the above configuration, a workstation or server with one Visual LANSA Repository is used to store information from one LANSA for i system. More than one Slave System can store information from the same LANSA system, but there will be a separate local Visual LANSA Repository on each workstation for each LANSA system.

In the above configuration, a workstation or server database with two or more Visual LANSA Repositories is used to store information from different LANSA for i systems. The LANSA systems may reside on one IBM i or on different IBM i servers.

Prohibited Configuration

The following Master and Slave Repository configuration will cause problems and is therefore not supported:

A single Visual LANSA database must not be used to store information from more than one LANSA system on the IBM i. It does not matter whether the LANSA systems reside on one IBM i or on different IBM i. You must use multiple Visual LANSA Systems so that each system is separate.
