Hi All,

Today, we see one of the materialized refresh is running more than a day and it is still running?

This refresh is running as part of informatica etl job to refresh the MV, so not sure how to track which session running this informatica job to refresh mat view

I could not find sessin details via v$session using program as PMDTM(informatica) running dbms_refresh , i see the MV in invalid status, not sure whether this causing the slowness

OWNER MVIEW_NAME STALENESS COMPILE_STATE------------------------------ ------------------------------ ------------------- -------------------DWADMIN M_DB_UNIV NEEDS_COMPILE NEEDS_COMPILE

Please suggest how to troubleshoot this materialized view issue and what the are recommendation to avoid this issue.

Howdy, Stranger!
