nsrmmdbd

SYNOPSIS

       nsrmmdbd

DESCRIPTION

       The nsrmmdbd daemon provides an RPC-based database service to the local
       nsrd(1) and nsrmmd(1) daemons, and query-only network  access  to  Net-
       Worker clients.  The RPC program number provided by nsrmmdbd is 390107.
       The RPC version numbers provided by nsrmmdbd are 3, 4, and 5.  Nsrmmdbd
       is normally started by nsrd(1).

       The  daemon  manages  a  'media and save set database' located in the
       file /nsr/mm/mmvolume6.  The primary purpose  of  the  database  is  to
       remember  which  save  sets  reside  on which backup volumes.  Numerous
       access methods are provided to both save set and volume records  within
       the database.

FILES

       /nsr/mm/mmvolume6
                   File containing the volume data base.

       /nsr/mm/cvt A  temporary  file  created  when converting an older media
                   database schema to the present schema.

       /nsr/mm/.cmprssd
                   For performance and space reasons, the database is periodi-
                   cally  rebuilt  (or compressed).  This file is created each
                   time the database is rebuilt; its associated ctime is  used
                   to  determine  when  to  rebuild  the  database  again.  To
                   forcibly compress the database, remove this  file  and  run
                   nsrim.

       /nsr/mm/mmvolume6.s
                   This  temporary  file is created to hold the media database
                   information that will be saved to tape by nsrmmdbasm(1).

       /nsr/mm/mmvolume6.r
                   The file (created by nsrmmdbasm)  that  is  read  when  the
                   media database information is being recovered.

DIAGNOSTICS

       The nsrmmdbd  diagnostic  messages  will  normally  be  logged  to  the
       /nsr/logs/daemon.log file.

       Besides the messages listed below, nsrmmdbd may generate other diagnos-
       tics.  Any diagnostics other than those listed below indicate a serious
       problem  with  the media database.  It may be necessary to recover your
       media database using mmrecov(1) if that occurs.


       media conversion failed! reason
              Printed when the conversion  is  terminates  unsuccessfully.   A
              more  detailed reason may be appended to the message.  NetWorker
              cannot work until the media database is converted  successfully.

       media db is converting count volumes
              This is printed after the volumes' data has been dumped from the
              old database, but  before  it  has  been  loaded  into  the  new
              database.

       media db is converting count save sets
              This  is  printed after the save sets' data has been dumped from
              the old database, but before it has been  loaded  into  the  new
              database.

       media db is saving its data, this may take a while
              Printed  when  the  daemon is dumping its records to a temporary
              file when the database is  being  backed  up.   The  service  is
              unavailable while the database is dumping.

       media db is recovering, this may take a while
              Printed  when the daemon is reloading its database.  The service
              is unavailable while the data is being reloaded.

       media db is recovering old data, this may take a while
              Similar to the previous message, except that a pre-4.0  database
              is  being recovered and it will have to be converted before ser-
              vice resumes.

       media db is cross checking the save sets
              Printed each time the daemon is restarted.  Upon  start-up,  the
              daemon sanity checks its records before providing its service.

       media db is open for business
              Printed  after any of the previous messages are printed to indi-
              cate that the service is once again available.

       A copy of this process is already running!
              Another copy of nsrmmdbd(1) is currently running and has  exclu-
              sive  access  to  the media database.  Only one nsrmmdbd process
              should be running on a given machine at a time.  This can happen
              if  the  previous  nsrmmdbd  was  not  properly killed off.  Use
              nsr_shutdown(1) or ps(1) and kill(1) to identify  and  kill  off
              all the NetWorker daemons before restarting nsrd(1) again.

       Cannot open lock file
              An  internal  error,  check  the permissions on the /nsr/tmp and
              /nsr/mm directories.
