Startpart, Startseq, System – HP Neoview Release 2.5 Software User Manual

For a load operation where the

“operation” (page 62)

is “insert”, if the

“noaudit” (page 61)

option is true, the sorted option must also be true, otherwise an error is returned.

This option is ignored for extract operations.

startpart

startpart = system_partition_number

Value: a positive integer, ranging from 1 to the maximum number of partitions on the system

This option and the option

“endpart” (page 57)

, determine the start and end of a temporary

virtual partition you can create for the duration of a load or extract job.

For a load or extract job using virtual partitions, the only data processed is that belonging to the
“partition(s)” you specified in the control file. For maximum processing speed, use multiple
Transporter instances with virtual partitions that do not overlap.

startpart

must be less than endpart. If it is not, Transporter displays an error message and

terminates.

endpart

must be greater than startpart. If it is not, Transporter displays an error message

and terminates.

startseq

startseq = "sequence of characters"

startseq

, along with the

“endseq” (page 57)

option, are specific to named pipe sources and

allow specification of start and end sequence records.

This is an optional feature to allow data synchronization between Transporter and your
applications.

The start and end sequence records are considered “substitute” records. Whenever one of these
records is written to the pipe (either by Transporter during an extract operation, or by the
application during a load operation), it is terminated by an appropriate record separator.

sequence of characters

should not contain a record separator.

For a load operation when a pipe is read, Transporter discards any records read until the
startseq

record is seen. Transporter stops reading records once the endseq record has been

seen.

For an extract operation, Transporter writes the startseq record into the pipe before the first
data record. After all records have been written, the endseq record is written. The endseq
record is written even if errors are encountered.

system

system = "unqualified_Neo_systemname"

This option is required. There is no default value.

This option specifies the unqualified name of the primary segment on a Neoview system.

Example: to specify a Neoview system with the name neo0101.domain.com:

system = "neo0101"

taskrowsetsize

taskrowsetsize = number_of_records

The value must be an integer in the range from 1 to 100000.

This option specifies the number of records in each batch of rows Transporter exchanges with
the Neoview database.
