Applies to:Oracle Database - Enterprise Edition - Version 22.214.171.124 and later
Information in this document applies to any platform.
RHEL7/OL7 With 126.96.36.199 DB, DNFS enabled
DNFS is using multiple paths configured in oranfstab. But it never marks the paths as “down” when they get physically disconnected, so the DB hangs[DML/DDL Operations] until the interface becomes available again.
"ifdown eth2" behaves in expected way, transactions continues through other available path.
export: /export/fra/ora mount: /oradata/fra
No errors were seen from any of the logs. Also the same setup work in expected way in RHEL6/OL6
Test failover scenario to confirm the high availability
