Object

scalar r/w SNMPv2-TCTestAndIncr 
An advisory lock used to allow cooperating SNMP
Command Generator applications to coordinate their
use of the Set operation in creating or modifying
views.
          
When creating a new view or altering an existing
view, it is important to understand the potential
interactions with other uses of the view.  The
vacmViewSpinLock should be retrieved.  The name of
the view to be created should be determined to be
unique by the SNMP Command Generator application by
consulting the vacmViewTreeFamilyTable.  Finally,
the named view may be created (Set), including the
advisory lock.
If another SNMP Command Generator application has
altered the views in the meantime, then the spin
lock's value will have changed, and so this creation
will fail because it will specify the wrong value for
the spin lock.
          
Since this is an advisory lock, the use of this lock
is not enforced.

How SNMP and these commands work

Scalars have one instance, identified by the .0 suffix.

Read the scalar instance
/usr/bin/snmpget -v2c -c '<community>' -Pud -Ir -OQUv -m 'SNMP-VIEW-BASED-ACM-MIB' -M '/opt/observium/mibs/rfc:/opt/observium/mibs/net-snmp' 'udp:<hostname>:161' 'SNMP-VIEW-BASED-ACM-MIB::vacmViewSpinLock.0'

Syntax

SNMPv2-TCTestAndIncr
Source
SNMPv2-TCTestAndIncr
Base type
Integer32
Type Description
Represents integer-valued information used for atomic
operations.  When the management protocol is used to specify
that an object instance having this syntax is to be
modified, the new value supplied via the management protocol
must precisely match the value presently held by the
instance.  If not, the management protocol set operation
fails with an error of `inconsistentValue'.  Otherwise, if
the current value is the maximum value of 2^31-1 (2147483647
decimal), then the value held by the instance is wrapped to
zero; otherwise, the value held by the instance is
incremented by one.  (Note that regardless of whether the
management protocol set operation succeeds, the variable-
binding in the request and response PDUs are identical.)
          
The value of the ACCESS clause for objects having this
syntax is either `read-write' or `read-create'.  When an
instance of a columnar object having this syntax is created,
any value may be supplied via the management protocol.
          
When the network management portion of the system is re-
initialized, the value of every object instance having this
syntax must either be incremented from its value prior to
the re-initialization, or (if the value prior to the re-
initialization is unknown) be set to a pseudo-randomly
generated value.
