Avoiding Deadlocks: The Lookaside Database

The setting of the under_NIS_server token in the seos.ini configuration file has a default setting of yes to avoid deadlocks. The token tells CA ControlMinder to use its own internal name resolution tables instead of NIS, DNS, or the nscd cache. Unless otherwise specified, these tables reside in memory.

CA ControlMinder internal name resolution is much faster than NIS name resolution and even faster than using files; using CA ControlMinder internal name resolution improves performance even in an environment where there is no danger of deadlocks.

Note: There is no cache for the internal name resolution tables in the lookaside database. CA ControlMinder uses an open file handle to read data from the tables.
