Symptoms

When doing an ON-COMMIT refresh on a distributed mview (that is, the mview and master table are in different databases), you get an ORA-600 [4080] error.  In rare cases, you may also see an ORA-600 [4886], although the ORA-600 [4886] can also be caused by issues other than on-commit distributed materialized views.

• You will see something like the following in the alert log: 
  
  
  ORA-00600: internal error code, arguments: [4080], [2], [131], [], [], [], [], []

  Following on-commit snapshots not refreshed :
  <owner>.<mview_name>

• The "Current SQL" in the tracefile may look like this:
  
  
  select log, oldest, oldest_pk, oldest_oid, oldest_new, youngest+1/86400, flag, yscn, oldest_seq from sys.mlog$ where mowner = :1 and master = :2 for update
