Restart types.
Changes in MySQL Cluster configuration parameters do not take effect until the
cluster is restarted. The type of restart required to change a given parameter is indicated in the
summary tables as follows:
•
N
—Node restart: The parameter can be updated using a rolling restart (see
Section 17.5.5,
“Performing a Rolling Restart of a MySQL Cluster”
).
•
S
—System restart: The cluster must be shut down completely, then restarted, to effect a change in
this parameter.
•
I
—Initial restart: Data nodes must be restarted using the
--initial
[1619]
option.
For more information about restart types, see
Section 17.3.3, “Overview of MySQL Cluster
Configuration Parameters”
