NSRINDEXD(8) Legato NetWorker 3.0 NSRINDEXD(8)
NAME
nsrindexd - NetWorker index daemon
SYNOPSIS
nsrindexd [ -j ]
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 ser
vice to the server nsrd(8) daemon; direct network access to this ser
vice 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 syn
chronize their access to an index.
OPTIONS
-j Causes more checking of the database file(s) to be done during
startup.
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 run
ning, the nsrck program must be run before
nsrindexd is restarted.
/nsr/index/.ssid_low_high_clientname
These files are used keep track of pending
record deletes from clientname's index. Ssid
identifies the save set to be process, low and
high are the offsets within the save set, and
clientname is the database containing the
records. Index records are deleted as a result
of volumes being deleted or purged via the
mm(8) command or with the networker(8) volume
or index management windows. After nsrindexd
