Analyze the Log Records
After you isolate collided records in the collision log, you can use Progress 4GL to analyze records down to the field level. Follow these steps:
For more information about these statements, see the Progress Language Reference .
Resolve Collisions and Propagate Results
After you determine the differences between records that have collided, you can resolve the collisions in any number of ways. For example:
- After determining field differences using BUFFER–COMPARE, you can use Progress 4GL to select the record to replicate based on a hierarchy of key fields, for example, time or user.
- If certain collisions need to be addressed manually by an administrator, you could write the conflicts to another table for manual resolution or reporting purposes.
The way you resolve collisions depends upon your business requirements. The Progress 4GL allows you to develop procedures that support all of your requirements.
