Optimize HPOM node name resolution


Several enhancements have been implemented to improve the performance of HPOM for Windows node name resolution. The speed of the node name resolution has a significant impact on the following areas: These enhancements will help resolve (or at least reduce) the following performance related problems: Managed environments that do not make use of DHCP will experience the largest benefits. Here, an optional memory based cache can be configured which drastically reduces the number of the Windows API calls gethostbyname() and gethostbyaddr(). However, environments using DHCP can also take advantage of a modified ip-address verification which tries to avoid unnecessary reverse node name resolution.

To make use of the enhancements, you must configure several values using the Server Configuration dialog box. If the values are not set, then the enhancements will not take effect. See the Related Topics for enhancement details.
