How to use system events of CodeUnit 1.

How can I use below system events of CodeUnit 1.
• LOCAL [IntegrationEvent] OnAfterOnGlobalInsert(RecRef : RecordRef)
• LOCAL [IntegrationEvent] OnAfterOnDatabaseInsert(RecRef : RecordRef)

Event “OnAfterOnDatabaseModify” works after setting up the “Integration Service” but not for the OnAfterOnDatabaseInsert. So need help to get the correct steps to configure the system events.

Thanks,
