The nis_cachemgr should run on all NIS+ clients. The cache manager maintains a cache of location information about the NIS+ servers that support the most frequently used directories in the namespace, including transport addresses, authentication information, and a time-to-live value.
The cache manager makes requests as a client machine. Make sure the client machine has the proper credentials, or instead of improving performance, the cache manager will degrade it.
When using the Service Management Facility (SMF), the cache manager has a dependency on the NIS+ service, so cache manager starts and stops along with the NIS+ service. Use the svcadm command to start, stop, or restart the NIS+ service.
client% svcadm enable /network/rpc/nisplus:default client% svcadm disable /network/rpc/nisplus:default client% svcadm restart /network/rpc/nisplus:default
When you stop and start the NIS+ service, the cache manager is restarted but it retains the information in the /var/nis/NIS_SHARED_DIRCACHE file. The information in the cold-start file is simply appended to the existing information in the cache file. Use the -i option to clear the cache file and re-initialize it from the contents of the client's cold-start file.
