Instrumentation Functions for
SNMP-VIEW-BASED-ACM-MIB
</DIV>
<H3>DESCRIPTION</H3>
<DIV CLASS=REFBODY>
<P>The module <CODE>snmp_view_based_acm_mib</CODE> implements the instrumentation functions for the
SNMP-VIEW-BASED-ACM-MIB, and functions for configuring the database.
<P>The configuration files are described in the SNMP User's Manual.
</DIV>

<DIV CLASS=REFBODY>
<P>This function is called from the supervisor at system
start-up.
<P>Inserts all data in the configuration files into the
database and destroys all old rows with StorageType
<CODE>volatile</CODE>. The rows created from the configuration file
will have StorageType <CODE>nonVolatile</CODE>.
<P>All <CODE>snmp</CODE> counters are set to zero.
<P>If an error is found in the configuration file, it is
reported using the function <CODE>config_err/2</CODE> of the error
report module, and the function fails with the reason
<CODE>configuration_error</CODE>.
<P><CODE>ConfDir</CODE> is a string which points to the directory
where the configuration files are found.
<P>The configuration file read is: <CODE>vacm.conf</CODE>.
</DIV>

<P>Inserts all data in the configuration files into the
database and destroys all old data, including the rows with
StorageType <CODE>nonVolatile</CODE>. The rows created from the
configuration file will have StorageType <CODE>nonVolatile</CODE>.
<P>Thus, the data in the SNMP-VIEW-BASED-ACM-MIB, after this
function has been called, is the data from the configuration
files.
<P>All <CODE>snmp</CODE> counters are set to zero.
<P>If an error is found in the configuration file, it is
reported using the function <CODE>config_err/2</CODE> of the error
report module, and the function fails with the reason
<CODE>configuration_error</CODE>.
<P><CODE>ConfDir</CODE> is a string which points to the directory
where the configuration files are found.
<P>The configuration file read is: <CODE>vacm.conf</CODE>.
