Database Logging Configuration

When you set up the same database on the primary and secondary server (so you will have two actual databases that, under normal operation, will be identical) you need to identify them for data logging.

  • Redundancy configuration overview.
  • Redundancy configuration steps.

Redundancy Configuration Overview

In a redundant configuration:

  • The primary and secondary servers log data in parallel to their own database.
  • The primary server logs to the database on the primary SQL Server.
  • The secondary server logs to the database on the secondary SQL Server.

The only time the primary or secondary server will connect to the other node's database is when the data on the two servers needs to be merged.

  • The CIMPLICITY server redundancy operation requires that the:
  • Primary server be aware of the secondary SQL Server
  • Secondary server be aware of the primary SQL Server
  • P = Primary Server
  • S = Secondary Server

Redundancy Configuration Steps

In logged database redundancy, configure CIMPLICITY server redundancy, on both the primary and secondary server,  through Windows Control Panel..

Step Description
Step 1 Configure the Windows ODBC Data Source Administrator
Step 2 Identify the Database Logger data source in a CIMPLICITY project.
