Last updated on JULY 25, 2017
Applies to:Oracle Exalogic Elastic Cloud Software - Version 126.96.36.199.161018 to 188.8.131.52.170117
Exalogic Elastic Cloud X4-2 Hardware - Version X4 to X4 [Release X4]
Exalogic Elastic Cloud X5-2 Hardware - Version X5 to X5 [Release X5]
Oracle Virtual Sever (64-bit)
In X5-2 Exalogic environment, we can see /var/log in two NM2-GW switches are quickly exhausted.
Due to this issue:
- GW switch function compromised by dysfunctional opensmd and whereismasterd service.
- No master SM in IB fabric network.
- Dysfunctional jobs like creating guest vServers, restart Control stack and etc in Exalogic.
- Outage in Exadata like missing default IPoIB netowrk in compute and cell node
Upgrading to Oct 2016 PSU or Jan 2017 PSU.
