Snapshot/MView Log Grows Due To Missing/Invalid Snapshot (Doc ID 1031924.6)

Last updated on FEBRUARY 05, 2016

Applies to:

Oracle Database - Enterprise Edition - Version 8.1.7.4 and later
Information in this document applies to any platform.

Symptoms

 

If a snapshot becomes invalid or lost, and is not formally dropped
i.e. drop user cascade , a snapshot entry remains in the sys.slog$ table
on the master site.   
 
The snapshot log that the invalid snapshot refreshed against will continue to
grow since it thinks there are other snapshots that still
need to refresh these entries.
