Description

Use TCPSOURCETIMER or NOTCPSOURCETIMER to specify whether the Collector adjusts the timestamps of each record from the source system to the timestamps of the target system. When transmitting data to trails or files (RMTFILE or RMTTRAIL) on the target system using the TCP/IP Collector, the default is to adjust the timestamps. Although timestamps are stored in Greenwich Mean Time (GMT), the clocks of the source and target systems are frequently un-synchronized. Adjusting those timestamps allows Manager and GGSCI to calculate the true latency between the source and target systems.

However, when data is moved over TCP/IP between two NonStop systems and the systems are also linked with an Expand network, this adjustment is already made. Under those conditions, specify NOTCPSOURCETIMER to avoid the incorrect "double adjustment." NOTCPSOURCETIMER should be used when a Replicat on the target system uses @GETENV to get the COMMITTIMESTAMP header field for any column mapping.
