FLUSH NAME_CACHE

FLUSH NAME_CACHE

Flushes RTR's internal network name cache.

Format

FLUSH NAME_CACHE

Command Qualifiers	Defaults
/CLUSTER	/NOCLUSTER
/NODE[=node-list]	/NODE=default-node-list

Description

The FLUSH NAME_CACHE removes information for all known nodes from RTR's internal network name cache.

Network links could become unstable if a Distributed Name Service (DNS) was configured improperly or the service was slow in responding. During extreme DNS latency, RTR could time-out the connections to nodes waiting for a DNS response. To avoid these problems, RTR has implemented an internal node-name- to-id cache; this reduces RTR's exposure to degraded name servers. The contents of the cache can be deleted the command FLUSH NAME_CACHE.

FLUSH NAME_CACHE may be used if the network has been reconfigured or nodes have changed their addresses.

Qualifiers

/CLUSTER /NOCLUSTER (D)

Specifies that the command is executed on all the nodes in the cluster.

If neither /NODE nor /CLUSTER is specified then the command is executed on the nodes specified by the latest SET ENVIRONMENT command. If no SET ENVIRONMENT command has been entered then the command is executed only on the node where the command was issued.

Note: In environments that do not support clustering, use of the /CLUSTER qualifier will cause the relevant command to be executed on the local node only.

/NODE[=node-list] /NODE=default-node-list (D)

Specifies that the command is executed on all nodes specified in node-list. If node-listis omitted then the command is executed only on the node where the command was issued.
