There is a possibility of Disk I/O contention on the IBM® Campaign System database server as well. Depending on your flowchart, a large amount of data may be written to the
UA_CONTACTHISTORY table. For example, say you are running five multiple concurrent complex flowcharts, which are writing a large amount of data to
UA_CONTACTHISTORY simultaneously. In this case, spreading database table spaces across multiple disks can improve performance.
