Fileset/FTP Local Scheduling pane

This tables shows scheduling parameters:

Parameter Description
Read Interval

Specify the minimum time, IBREADINTERVAL, in seconds, to wait between reading from a file.

This tells the driver to process a message every IBREADINTERVAL seconds as long as there is work to do. For example, when there are input files available.

In general, IBREADINTERVAL is fairly low so that the driver rapidly processes inbound messages.

Max Messages

Specify the maximum number of messages to read from the file on each read interval.

Scan Interval

Specify the minimum time IBSCANINTERVAL, in seconds, between inbound directory scans for most message files.

This is the (minimum) number of seconds between inbound directory scans to look for new work.

This option is disabled if Use advanced scheduling is selected.

Scan Mode

For scheduling, there are two scanning options:

  • Serial

    This option scans and picks the files in one of the IB directories in each interval.

  • Parallel

    This option scans all of the IB directories and then picks all of the files in each interval.

The scan order is the same as the directories order that is configured by the user.

The default mode is serial mode. This mode is backwards compatible.

Example:

The directory list is: one, two, three, four.

Only directory four contains a file.

Read Interval is 5.

Scan Interval is 20.

In Serial mode, four scan cycles are completed to get to that file, for a total of 80 seconds.

In Parallel mode, it takes 20 seconds.

Use advanced scheduling

Select this to schedule recurring events, such as cycling log or SMAT files.

Then, click Setup to open the Scheduling dialog box.
