To start the cache manager, enter the nis_cachemgr command (with or without the -i option):
client% nis_cachemgr client% nis_cachemgr -i |
Without the -i option, 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 file. The -i option clears the cache file and re-initializes it from the contents of the client's cold-start file.
To stop the cache manager, kill it as you would any other process.
