Survivor Calculator

The survivor calculator determines which information from each system record in an object profile is stored in the SBR for that profile. The calculator uses information defined by the system administrator to calculate the SBR. By default, the survivor calculator uses a weighted strategy for most fields, using the relative reliability assigned to each system in combination with the reliability given to the most recently updated value.

For some fields, such as alias and auxiliary IDs, a union strategy is typically used. This means that all unique alias names and auxiliary IDs from all systems are included in the SBR. For detailed information about the survivor calculator and configuring the survival strategy, see Understanding Sun Master Index Configuration Options (Repository) and Configuring Sun Master Indexes (Repository).
