nisshowcache(1M) System Administration Commands nisshowcache(1M)NAME
nisshowcache - NIS+ utility to print out the contents of the shared cache file
SYNOPSIS
/usr/lib/nis/nisshowcache [-v]
DESCRIPTION
nisshowcache prints out the contents of the per-machine NIS+ directory cache that is shared by all processes accessing NIS+ on the
machine. By default, nisshowcache only prints out the directory names in the cache along with the list of active servers. The shared cache
is maintained by nis_cachemgr(1M).
OPTIONS -v Verbose mode. Print out the contents of each directory object, including the information on the server name and its universal
addresses.

nis_cachemgr - NIS+ utility to cache location information about NIS+ servers
SYNOPSIS
/usr/sbin/nis_cachemgr [-i] [-v]
DESCRIPTION
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 DIAGNOSTICS section, below. Addition-
ally, a "keylogin -r " should be done on the machine.
svc:/network/rpc/keyserv:default is required for NIS+ operation. See NOTES.
OPTIONS -i Force nis_cachemgr to ignore the previous cache file and reinitialize the cache from just the cold start file. By default, the
cache manager initializes itself from both the cold start file and the old cache file, thereby maintaining the entries in the
cache across machine reboots.
-v This flag sets verbose mode. In this mode, the nis_cachemgr program logs not only errors and warnings, but also additional status
messages. The additional messages are logged using syslog(3C) with a priority of LOG_INFO.

The nis_cachemgr daemon logs error messages and warnings using syslog(3C). Error messages are logged to the DAEMON facility with a prior-
ity of LOG_ERR . Warning messages are logged with a priority of LOG_WARNING. Additional status messages can be obtained using the -v
option.
NOTES
NIS+ might not be supported in future releases of the SolarisTM Operating Environment. Tools to aid the migration from NIS+ to LDAP are
available in the Solaris 9 operating environment. 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 ser-
vice's status can be queried using the svcs(1) command.
