It is important to note that increasing the TCP socket buffer size directly affects the
amount of system memory consumed by each socket. When tuning the TCP socket buffer
size at the operating system level, it is imperative to ensure the current amount of system
memory can support the expected number of network connections with the new buffer
size.
Additional 5620 SAM Database throughput optimizations
In addition to the optimizations above, the 5620 SAM Database workstation requires
changes to the sqlnet.ora and listener.ora files that are contained in the
oracle/network/admin directory. The lines with the SEND_BUF_SIZE and
RECV_BUF_SIZE should be uncommented (delete the “#” character), and set to 3 times
the BDP value calculated above. The database should be shutdown when this change is
made.
Network reliability considerations
Network reliability considerations
This section describes network reliability considerations.
Reliability between 5620 SAM components
The 5620 SAM requires reliable network communications between all the SAM
Components:
•
5620 SAM Servers
•
5620 SAM Databases
•
5620 SAM Auxiliaries
•
5620 SAM Auxiliary Databases
•
5620 SAM Analytics Server
•
5620 SAM GUI Clients and 5620 SAM Client Delegate Server
•
5620 SAM OSS Clients
The performance and operation of 5620 SAM can be significantly impacted if there is any
measurable packet loss between the 5620 SAM workstations. Significant packet loss can
cause 5620 SAM reliability issues.
Alcatel-Lucent supports the deployment of 5620 SAM using the RHEL IP Bonding
feature. The support for IP Bonding is intended only to provide network interface
redundancy configured in active-backup mode for IP Bonding. All other modes of IP
Bonding are not supported. RHEL documentation should be consulted on how to
configure IP Bonding.
