Dual TCP/IP Overview
Dual TCP/IP provides two connections between the host and the library using the
primary port 2B and secondary 2A of the HBC/HBCR card. If the primary host
connection fails, the library automatically uses the secondary connection.

Minimum Requirements for Dual TCP/IP
■ ACSLS 7.1 with PUT0701 for Solaris or AIX. Oracle recommends ACSLS 8.1 or
above.
■ NCS 6.2 with the following PTFs for HSC/MVS/VM: SOS620 L1H168G, SMS620
L1H168F, and MSP: MSP PTF LF620DL.
■ All switch or router ports must be configured to auto negotiate. The SL8500 ports
are configured to auto negotiate by default and support 10/100 Mbps speeds.
■ Hardware activation file (see Chapter 5, "Activating Optional Features")
Using a Shared Network
If you must use a shared network:
■ Directly connect the library to a switch or router that filters out undirected
(broadcast) traffic.
■ Place the library on its own subnet. This may protect the library from receiving
broadcast messages.
■ Use a managed switch or router to:
Note: Oracle recommends a private network for maximum
throughput, minimum resource contention, and higher security.
