LASTSEQ Parameter
All event records contain a unique timestamp that consists of date, time, and sequence number. Each EVENT SERVICES request is associated with an ID. The IBM® Connect:Direct® CICS API creates a restart record for an ID when an EVENT SERVICES CREATE command is processed.
After an event record is successfully delivered to the Transient Data Queue, its timestamp is saved in the restart file. If event services processing ends abnormally, the restart record is retained. The restart record is also retained when you specify KEEPRREC (keep restart record) in the EVENT START statement.
When an EVENT SERVICES CREATE command is processed, the restart file is searched for a record matching the ID of the CREATE. If a match is found, the date, time, and sequence number of the last successfully delivered event record is returned. When you use the time specification in conjunction with the LASTSEQ parameter, you must include hours, minutes, seconds, and hundredths of seconds in the format hh:mm:ss.th.
