Step 2.7. Do advanced Logging Configuration

The Advanced tab in the data log's Table Properties dialog box enables you to:

• Disable logging actions for the table that you are configuring.
• Override the queue size that is specified in the Database Logger's Logging Properties dialog box.
• Select and control bulk insertion for Microsoft SQL Server or MSDE.

Select the Advanced tab in the data log's Table Properties dialog box.

Configuration options are as follows.

1	Disable logging actions
2	Write a queue size/Use default
3	Use bulk insertion (Microsoft SQL Server and MSDE only)

1	Disable logging actions

Select whether or not to log data to the table.

Do one of the following in the Disable logging actions checkbox.

Option	Description
Check	Do not log data to the selected table.
Clear	Log to the selected table when the CIMPLICITY project is running.

2	Write a queue size/Use default

Choose one of the following.

Option	Description
Use default	Check ??to use the universal size specified on the Parameters tab in the Database Logger's Logging Properties dialog box.
Write queue size field	Clear Use default. Enter a number in the ??that supports the worst-case logging during activity bursts. Example: If 10 points are being logged to the table, you should have a queue size of at least 10 in case the points' logging conditions all occur simultaneously.

3	Use bulk insertion (Microsoft SQL Server and MSDE only)

Use bulk insertion enables you to take advantage of the Database Logger's bulk insertion capability (Microsoft SQL Server or MSDE only).

1. Check Use bulk insertion.
2. Select the Maximum number of insertions that your system can handle.
3. Select the interval between insertions in the Bulk insertion rate field.

The Database Logger will be triggered to insert records, based on whichever specification occurs first.

Example

You specify the:

Maximum number of insertions	=	1000
Bulk insertion rate	=	60 seconds

As a result:

If the Database Logger:	Then the Database Logger:
Collects 1000 records within 60 seconds.	Inserts the records into the log.
Does not collect 1000 records within 60 seconds.	Inserts whatever records have been collected.
