CREATE PARTITION
/CONCURRENT (D)
/NOCONCURRENT
Specifies that concurrent servers are allowed for this partition.
/KEYn=keysegdesc
Specifies a partition key segment. Up to nine key segments may be defined for
a partition (KEY1, KEY2,... up to KEY9). (If more than nine key segements are
required, a named partiton can be created using the
rtr_open_channel( )
call.)
The syntax of the KEYn qualifier is:
/KEYn= (type_of_key=[signed|unsigned|string], -
length_of_key=nnnn, -
offset_of_key=nnnn, -
low_bound=[string|nnnn] -
high_bound=[string|nnnn]
type_of_key=
Specifies the field type of the key. The
key-type
must be one of
unsigned
,
signed
or
string
. The default is
unsigned
.
length_of_key=nnnn
Specifies the length of the key field in enqueued messages
in bytes. For signed or unsigned ints, length may be either one, two, four or eight
bytes. The default value for
key-length
is four bytes.
offset_of_key=nnnn
Specifies the offset of the key within the messages in bytes.
The default is zero, that is, the key is at the start of the messages.
low_bound=
Specifies the lower bound of the key range that servers in the
partition will service. The interpretation of
low-bound
depends on the key type; if
the key is of type string then it is interpreted as text, otherwise it is interpreted
as a numeric value. The default for
low-bound
is the smallest possible value that
can fit in the specified key type.
If the key bound value length is less than the key length (given in
length_of_key
), the key bound will automatically be null-padded to the required
length.
high_bound=
Specifies the upper bound of the key range that servers in the
partition will service. The interpretation of
high-bound
depends on the key type.
If the key is of type string then it is interpreted as text, otherwise it is interpreted
as a numeric value. The default for
high-bound
is the largest possible value that
can fit in the specified key type.
If the key bound value length is less than the key length (given in
length_of_key
), the key bound will automatically be null-padded to the required
length.
If the specified key range overlaps that of an existing partition in the facility, or
if the key segment description conflicts with an existing definition, the command
fails.
/FACILITY
Specifies the name of the facility in which the partition is being created.
/NODE[=node-list]
/NODE=default-node-list (D)
Specifies that the command is executed on all nodes specified in
node-list
.If
node-list
is omitted then the command is executed only on the node where the
command was issued.
