Rockwell Automation FactoryTalk Historian Classic for Batch User Guide - Manual (Page 25)

Configuring FactoryTalk Historian for Batch Chapter 2
settings provide for optimum performance, but you may need to
adjust them based on your server, network traffic, and database size.
If you forgot to select this option during installation, you will need
to enter the appropriate data collection values in the FactoryTalk
Batch Equipment Editor Server Options dialog box, on the Batch
Reporting tab:
• Archiver (Incremental)
• Maximum Records Per Transaction = 1000
• Incremental Period = 5 Minutes
The minimum value that can be entered in the Maximum Records
Per Transaction field is 0 and the maximum is 10000. However,
the maximum number of records that can be successfully archived in
a single transaction depends on the capabilities of your computer,
and may be significantly less than 10000. If you encounter Time
Out messages in the
batcharc log, reduce the value in the Maximum
Records Per Transaction field. If you enter a value of 0, all records
will be committed in a single transaction at the end of the batch.
The data collection settings can be adjusted for either optimum
speed or optimum data access. While the previous section
recommended settings for optimum performance, the following
settings are recommended for faster access to event data being
archived:
• Archiver (Incremental)
• Maximum Records Per Transaction = 10
• Incremental Period = 1 minute or less.
These values ensure that events are processed, stored, and
committed to the database as quickly as possible, making this data
available for prompt retrieval.
