Chapter 2 Configuring FactoryTalk Historian for Batch
TIP
These settings are a guideline and may vary depending on the number
of events generated per batch, the duration of the batch, etc.
This section explains the configuration requirements for using
FactoryTalk Historian for Batch with multiple batch servers. It also
includes recommendations for optimizing FactoryTalk Historian
for Batch performance in a multiple batch server environment.
A range for the CreateIDs must be established and followed. This is
necessary to ensure the same CreateID (referred to as UniqueID in
FactoryTalk Historian for Batch) is not generated by more than one
batch server. For example the CreateID in the
batchsvr.ini file for
Batch Server1 should be initialized to 1000000, the CreateID in the
batchsvr.ini file for Batch Server2 should be initialized to 2000000,
and the CreateID in the
batchsvr.ini file for Batch Server3 should be
initialized to 3000000.
After setting these values be sure to restart each Batch Server to
ensure the new CreateID ranges are picked up by the servers.
For performance reasons, incremental archiving should be used
rather than end of batch archiving. The incremental period should
be set depending on the number of event records generated and the
frequency with which those event records are generated. As a
guideline, an incremental period of 10 minutes or less is
recommended. See the
FactoryTalk Batch Archiver User Guide for
more information on setting up incremental archiving and changing
the incremental period.
To minimize the load on the FactoryTalk Historian for Batch
database server, an incremental range should be established. The
incremental range should be long enough to allow each Archiver
time to process its Batch Server event journal files. For example, if
the incremental period is set to 10 minutes, then the following range
could be established:
