• IQ.CLUSTERING - REQUIREMENTS FOR IQ.CLUSTERING
7.2 Requirements for iQ.Clustering
To use iQ.Clustering most efficiently and with all functions, observe the following:
• iQ.Clustering requires a separate license.
• Under normal circumstances, two servers will be sufficient to cover standard
tasks (fail-safety and load balancing).
• The new "Reserve“ and "Process" method is always used, even if checking
the own mail.box only.
• Appropriate access rights to the mail.box(es). The servers need Manager
rights (including deletion) to access each other’s mail.box.
• The system time settings on the servers must not differ significantly.
7.2.1 Email Checking Sequence
The description below explains the working principle:
1. The MailGrabber checks the mail.box(es) to be monitored for new documents.
2. The MailGrabber attempts to reserve any documents found -> new status in
the dispatched for view.
3. The working threads only process documents that have been successfully
reserved by the server ($TKCheckServer field).
4. If a reserved document is not processed within 15 minutes, it is reset.
5. If there are any reserved documents when the MailGrabber is stopped or
started, the reservation is removed.
The following figure illustrates the working principle for having the mail.boxes on
an zOS server checked by two Windows computers, with the MailGrabbers mutually
monitoring each other:
