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.
