Deployment Considerations - AIX

When deploying Coherence on AIX please be aware of the following:

Multicast and IPv6

AIX 5.2 and above default to running multicast over IPv6 rather then IPv4. If you are running in a mixed IPv6/IPv4 environment you will need to configure your JVMs to explicitly use IPv4. This can be done by setting the java.net.preferIPv4Stack system property to true on the Java command line. See the IBM 32-bit SDK for AIX User Guide for details.

Unique Multicast Addresses and Ports

On AIX it is suggested that each Coherence cluster use a unique multicast address and port, as some verions of AIX will not take both into account when delivering packets. See the multicast-listener for details on configuring the address.

tangosol-license.xml

The tangosol-license.xml file contains signed data elements and thus it is important that it be transfered in binary form to prevent any CR/LF based conversions when moving between Windows and Unix operating systems. If the file is transfered in ASCII mode some or all of the included licenses may fail the signature check and be deemed invalid.
