/usr/sbin/nis_cachemgr [-i] [-v]
The nis_cachemgr daemon maintains a cache of NIS+ directory objects and active servers for domains. It is responsible for locating servers for a domain on behalf of client processes. This improves performance because only one process has to search for servers. The cache contains location information necessary to contact the NIS+ servers. This includes transport addresses, information neeeded to authenticate the server, and a time to live field which gives a hint on how long the directory object can be cached. The cache helps to improve the performance of the clients that are traversing the NIS+ name space. nis_cachemgr should be running on all the machines that are using NIS+. However, it is not required that the nis_cachemgr program be running in order for NIS+ requests to be serviced.
The cache maintained by this program is shared by all the processes that access NIS+ on a machine. The cache is maintained in a file that is memory mapped by all the processes. See mmap(2). On start up, nis_cachemgr initializes the cache from the cold start file and preserves unexpired entries that already exist in the cache file. See nisinit(1M). Thus, the cache survives machine reboots.
The nis_cachemgr program is normally started from a system startup script. nisshowcache(1M) can be used to look at the cached objects and active servers.
The nisprefadm(1M) command can be used to control which NIS+ servers the nis_cachemgr program will try to select.
The nis_cachemgr program makes NIS+ requests under the NIS+ principal name of the host on which it runs. Before running nis_cachemgr, security credentials for the host should be added to the cred.org_dir table in the host's domain using nisaddcred(1M). Credentials of type DES will be needed if the NIS+ service is operating at security level 2 (see rpc.nisd(1M)). See the section, below. Additionally, a "keylogin -r " should be done on the machine.
svc:/network/rpc/keyserv:default is required for NIS+ operation. See NOTES.

keylogin(1), svcs(1), nisaddcred(1M), nisinit(1M), nisprefadm(1M), nisshowcache(1M), rpc.nisd(1M), svcadm(1M), mmap(2), rpc(3NSL), syslog(3C), nisfiles(4), attributes(5), smf(5)
The nis_cachemgr daemon logs error messages and warnings using syslog(3C). Error messages are logged to the DAEMON facility with a priority of LOG_ERR . Warning messages are logged with a priority of LOG_WARNING. Additional status messages can be obtained using the -v option.
NIS+ might not be supported in future releases of the Solaris operating system. Tools to aid the migration from NIS+ to LDAP are available in the current Solaris release. For more information, visit http://www.sun.com/directory/nisplus/transition.html.
The nis_cachemgr service is managed by the service management facility, smf(5), under the service identifier:
svc:/network/rpc/nisplus:default
Administrative actions on this service, such as enabling, disabling, or requesting restart, can be performed using svcadm(1M). The service's status can be queried using the svcs(1) command.
