NSRINDEXD(8)               Legato NetWorker 4.1.1               NSRINDEXD(8)


NAME
       nsrindexd - NetWorker file index daemon

SYNOPSIS
       nsrindexd

DESCRIPTION
       The nsrindexd daemon is started by the server nsrd(8) daemon.  It
       should not be started by hand.  The daemon provides an RPC-based
       service to the server nsrd(8) daemon; direct network access to this
       service is not allowed.  The RPC program and version numbers provided
       by nsrindexd are 390105 and 4, respectively.

       The service provided to the NetWorker system is designed for high
       performance insertion and deletion of save records into indexes.
       This performance is obtained by keeping information cached in the
       nsrindexd process address space.  When the NetWorker system wishes to
       commit a save session's records, it notifies the nsrindexd daemon
       (via a remote procedure call) to flush its volatile state to its
       file(s).

       Since the daemon (or the server machine) may crash at any time, the
       index files may be left in an inconsistent state.  Therefore, the
       maintenance program, nsrck(8) is run automatically by the nsrd daemon
       before the NetWorker service is started.

       Since nsrindexd and nsrck are run at the same time, both programs use
       an advisory file locking mechanism on the file db.SCAVENGE to
       synchronize their access to an index.

FILES
       /nsr/index/clientname/db
                             Where the client's index records are stored and
                             accessed.

       /nsr/index/clientname/db.SCAVENGE
                             When this file exists and nsrindexd is not
                             running, the nsrck program must be run before
                             nsrindexd is restarted.

DIAGNOSTICS
       waiting for lock on filename.
              This message indicates that another program is accessing the
              same file that is required by this daemon.  The daemon will
              wait for the advisory lock to be cleared.

       lock on filename acquired.
              Informative message that will eventually follow the previous
              message.
