Exalogic Best Practice: Configure Oracle Traffic Director (OTD) to use TCP instead of SDP
Last updated on JULY 20, 2016
Applies to:Oracle Exalogic Elastic Cloud Software - Version 184.108.40.206.0 and later
Compute nodes (dom0) in environments with Oracle Traffic Director (OTD) deployed within vServers (domU) hang intermittently followed by an automatic reboot cycle within hours. The frequency of such hangs/reboots is approximately 1-2 incidents per week depending on the load on the system. When a compute node hangs/reboots, all vServers on that node go offline, impacting services provided by those vServers. Manual intervention is typically required to bring the node and services back on line.
