Effective Version
MySQL 5.0.0
Restart Type: N
This parameter specifies how long the Cluster waits for all data nodes to come up before the cluster
initialization routine is invoked. This timeout is used to avoid a partial Cluster startup whenever
possible.
This parameter is overridden when performing an initial start or initial restart of the cluster.
The default value is 30000 milliseconds (30 seconds). 0 disables the timeout, in which case the
cluster may start only if all nodes are available.
StartPartitionedTimeout
Effective Version
MySQL 5.0.0
Restart Type: N
If the cluster is ready to start after waiting for
is still possibly in a partitioned state, the cluster waits until this timeout has also passed. If
StartPartitionedTimeout
This parameter is overridden when performing an initial start or initial restart of the cluster.
The default timeout is 60000 milliseconds (60 seconds).
StartFailureTimeout
Effective Version
MySQL 5.0.0
Restart Type: N
If a data node has not completed its startup sequence within the time specified by this parameter, the
node startup fails. Setting this parameter to 0 (the default value) means that no data node timeout is
applied.
For nonzero values, this parameter is measured in milliseconds. For data nodes containing
extremely large amounts of data, this parameter should be increased. For example, in the case of a
data node containing several gigabytes of data, a period as long as 10–15 minutes (that is, 600000
to 1000000 milliseconds) might be required to perform a node restart.
HeartbeatIntervalDbDb
Effective Version
MySQL 5.0.0
Restart Type: N
One of the primary methods of discovering failed nodes is by the use of heartbeats. This parameter
states how often heartbeat signals are sent and how often to expect to receive them. After
missing three heartbeat intervals in a row, the node is declared dead. Thus, the maximum time for
discovering a failure through the heartbeat mechanism is four times the heartbeat interval.
