TIMVCFAIL
TIMVCFAIL is a system parameter that specifies the time required for an adapter or virtual circuit failure to be detected. VSI recommends that the default value be used. VSI also recommends that this value be lowered only in OpenVMS Cluster of three CPUs or less, that the same value be used on each computer in the cluster, and that dedicated LAN segments be used for cluster I/O. TIMVCFAIL is a DYNAMIC parameter.
