Considerations Regarding ASG-TMON for Web Services when Changing the GMT Adjustment Factor

Setting the GMT adjustment factor forward (Standard Time):

The ASG-TMON for Web Services application within the Partner HUB must be stopped (shut down) when setting the GMT adjustment forward. To stop the ASG-TMON for Web Services application within the Partner HUB, issue the following MVS command:

F TUSHUBP,STOP TUSS

After setting the GMT offset forward you can immediately start the ASG-TMON for Web Services application. To start the ASG-TMON for Web Services application within the Partner HUB, issue the following MVS command:

F TUSHUBP,START TUSS

Data Considerations:

You can use the LFS log immediately without clearing it. There will be a time gap in the data for the time period the clock was set forward.

Setting the GMT adjustment factor backward (Daylight Saving Time):

The ASG-TMON for Web Services application within the Partner HUB must be stopped (shut down) when setting the GMT adjustment backward. To stop the ASG-TMON for Web Services application within the Partner HUB, issue the following MVS command:

F TUSHUBP,STOP TUSS

After setting the GMT offset backward you should wait until the clock has gained the time it was set back before starting the ASG-TMON for Web Services application. To start the ASG-TMON for Web Services application within the Partner HUB, issue the following MVS command:

F TUSHUBP,START TUSS

Data Considerations:

If you start the ASG-TMON for Web Services application before the clock gains the setback time, duplicate timed log records will be written to the LFS logs. The overlapping log records may show increased statistics for a particular hour or invalid summary data when building history files.
