Module: SNMP-VIEW-BASED-ACM-MIB
OID (symbolic): SNMP-VIEW-BASED-ACM-MIB::vacmViewSpinLock
OID (numeric): 1.3.6.1.6.3.16.1.5.1
Node type: OBJECT-TYPE
Type: TestAndIncr
Access: read-write
Description: 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.
What is vacmViewSpinLock?
This read-write advisory lock lets cooperating SNMP command-generator applications coordinate their use of Set operations when creating or modifying MIB views; an application retrieves the lock, checks vacmViewTreeFamilyTable for a unique view name, then sets the new view including the current lock value, and the set fails if the lock value has changed due to another application's concurrent modification. Admins' management tools use this internally to avoid two SNMP managers clobbering each other's view changes, though as an advisory lock its use isn't enforced by the agent. For example, a management application reads the spin lock as 42, creates a new view referencing lock value 42, and the change succeeds only if no other application incremented the lock in the meantime.
