The Node and Host Name Expansion feature provides the ability for the system administrator to set node and host names up to 255 bytes. This capability was previously available only as an optional product for HP-UX 11i v2.

Summary of Change

What’s New for Customers Migrating from HP-UX 11i v1 September 2005?

The product allows the customer to set longer node and host names (up to 255 bytes) for their HP-UX systems.

What’s New for Customers Migrating from HP-UX 11i v2 June 2006?

The product allows the customer to set longer node and host names (up to 255 bytes) for their HP-UX systems. This capability was previously available only as an optional product on HP-UX 11i v2 (Node and Host Name Expansion [NodeHostNameXpnd], revision B.11.23.01, product bundle).

Impact

The product allows the customer to set longer node and host names (up to 255 bytes) for their HP-UX systems.

Compatibility

The default HP-UX system parameters ensure that node and host names do not exceed the compatible lengths of 8 and 64 bytes, respectively. A new system tunable parameter, expanded_node_host_names, has been added by which the administrator can enable the system to accept node and host names up to 255 bytes in length.

Setting node and host names longer than 8 or 64 bytes, respectively, can cause some applications which use the node and/or host names to exhibit anomalous behavior or fail. It is strongly recommended that all the documentation (manpages and the whitepaper) be understood before enabling the system to accept longer names.

Performance

This product has no effect on system performance.
