|
|
This tool extracts current configuration information for data nodes, SQL nodes, and API nodes from one of a number of sources: an NDB Cluster management node, or its
|
|
config\&.ini
|
|
or
|
|
my\&.cnf
|
|
file\&. By default, the management node is the source for the configuration data; to override the default, execute ndb_config with the
|
|
\fB\-\-config\-file\fR
|
|
or
|
|
\fB\-\-mycnf\fR
|
|
option\&. It is also possible to use a data node as the source by specifying its node ID with
|
|
\fB\-\-config_from_node=\fR\fB\fInode_id\fR\fR\&.
|
|
.PP
|
|
\fBndb_config\fR
|
|
can also provide an offline dump of all configuration parameters which can be used, along with their default, maximum, and minimum values and other information\&. The dump can be produced in either text or XML format; for more information, see the discussion of the
|
|
\fB\-\-configinfo\fR
|
|
and
|
|
\fB\-\-xml\fR
|
|
options later in this section)\&.
|
|
.PP
|
|
You can filter the results by section (DB,
|
|
SYSTEM, or
|
|
CONNECTIONS) using one of the options
|
|
\fB\-\-nodes\fR,
|
|
\fB\-\-system\fR, or

\fB\-\-connections\fR\&.

Normally, the XML output produced by
|
|
\fBndb_config\fR
|
|
\fB\-\-configinfo\fR
|
|
\fB\-\-xml\fR
|
|
is formatted using one line per element; we have added extra whitespace in the previous example, as well as the next one, for reasons of legibility\&. This should not make any difference to applications using this output, since most XML processors either ignore nonessential whitespace as a matter of course, or can be instructed to do so\&.

The XML output also indicates when changing a given parameter requires that data nodes be restarted using the
|
|
\fB\-\-initial\fR
|
|
option\&. This is shown by the presence of an
|
|
initial="true"
|
|
attribute in the corresponding
|
|
<param>
|
|
element\&. In addition, the restart type (system
|
|
or
|
|
node) is also shown; if a given parameter requires a system restart, this is indicated by the presence of a
|
|
restart="system"
|
|
attribute in the corresponding
|
|
<param>
|
|
element\&. For example, changing the value set for the
|
|
Diskless
|
|
parameter requires a system initial restart, as shown here (with the
|
|
restart
|
|
and
|
|
initial
|
|
attributes highlighted for visibility):
|
|
.sp
|

.if n \{\

Currently, no
|
|
initial
|
|
attribute is included in the XML output for
|
|
<param>
|
|
elements corresponding to parameters which do not require initial restarts; in other words,
|
|
initial="false"
|
|
is the default, and the value
|
|
false
|
|
should be assumed if the attribute is not present\&. Similarly, the default restart type is
|
|
node
|
|
(that is, an online or
|
|
\(lqrolling\(rq
|
|
restart of the cluster), but the
|
|
restart
|
|
attribute is included only if the restart type is
|
|
system
|
|
(meaning that all cluster nodes must be shut down at the same time, then restarted)\&.
|
|
.sp
|
|
Deprecated parameters are indicated in the XML output by the
|
|
deprecated
|
|
attribute, as shown here:
|
|
.sp
|
|
.if n \{\
|
|
.RS 4
|

|
|
.nf
|
|
<param name="NoOfDiskPagesToDiskAfterRestartACC" comment="DiskCheckpointSpeed"

|
|
.sp
|
|
In such cases, the
|
|
comment
|
|
refers to one or more parameters that supersede the deprecated parameter\&. Similarly to
|
|
initial, the
|
|
deprecated
|
|
attribute is indicated only when the parameter is deprecated, with
|
|
deprecated="true", and does not appear at all for parameters which are not deprecated\&. (Bug #21127135)
|
|
.sp
|
|
Beginning with NDB 7\&.5\&.0, parameters that are required are indicated with
|
|
mandatory="true", as shown here:
|
|
.sp
|
|
.if n \{\
|
|
.RS 4
|
|
.\}
|
|
.nf
|
|
<param name="NodeId"

In much the same way that the
|
|
initial
|
|
or
|
|
deprecated
|
|
attribute is displayed only for a parameter that requires an intial restart or that is deprecated, the
|
|
mandatory
|

attribute is included only if the given parameter is actually required\&.

The

Unlike the options used with this program to obtain current configuration data,

use information obtained from the NDB Cluster sources when

\fBndb_config\fR, when used with the
