Enabling Case Analyzer to process Process Engine event logs which has a sequence number reset

Troubleshooting


Problem

All versions of Process Engine(PE) prior to Content Platform Engine (CPE) 5.2.1.2 use a 32-bit integer to store the auto-incremented sequence number. When the max value for this integer is reached, PE stops writing event log entries. This sequence number can be recycled by setting it to a smaller value that allows PE to continue writing event entries. Refer to the following document below on how to recycle the PE event log sequence: Checking and resetting the vwlog sequences in the Process Engine's database - http://www-01.ibm.com/support/docview.wss?uid=swg21960771 This document is the next in the series that explains the steps that are necessary to enable Case Analyzer to process the event logs with recycled sequence numbers

Symptom

Case Analyzer stops publishing PE event data for the given event log for which the sequence number is reset. It does not log any error information. This is due to the fact that the most recent sequence number it processed successfully is the integer max value and there are no new events greater than that number. Case Analyzer stays unaware that the sequence number is recycled/rolled over on the PE event log.
