One holdup can prevent the invoice from being printed, the order from being filled, or the requisition from being processed. Parameters can be viewed from the Baan Server's host computer to predict problems or delays before they become critical. As an example, if the Oracle database is running out of room to manage change requests, it will stop running, thereby freezing data and locking out users. The administrator can allocate more room to the Oracle tablespaces before this problem occurs if he or she can see the problem coming. Meaningful thresholds should be set that establish warning definitions.
Monitoring prevents problems when the threshold levels are exceeded.
Swap memory is used when copying entire processes from memory to secondary storage. Paging frees up real memory space by moving portions of a process to secondary storage. Both swap memory and paging should be monitored to maintain peak performance. Thresholds should be set for capacity limits and then carefully monitored to prevent overgrowth. Operating systems can be monitored to check critical parameters such as the size of the buffer cache and bandwidth.
