Improved Throughput

Frequent path switches caused by setting PSWEIGHT to EQUAL or SAMEROUT can lead to reduced throughput.

Use CA NetMaster NM for TCP/IP to improve throughput

1. From the command prompt, enter the following panel shortcut:

   /RTP
   

   The RTP Pipes List is displayed.

2. From the command prompt, enter the following command:

   SORT SW# D
   

   The RTPs are sorted by the number of path switches in descending order.

3. Scroll right to review the number of path switches and the reason for the last path switch.

   A high number of switches with the reason AUTO PATH SWITCH FOR PSRETRY indicates a possible problem.

4. From the command entry panel, enter the following command:

   D VTAMOPTS,OPTION=PSRETRY
   

   The VTAM options are displayed. Values of 0 indicate that there is no timer-based switching of RTPs.

5. From the command entry panel, enter the following command:

   D VTAMOPTS,OPTION=PSWEIGHT
   

   The VTAM options are displayed. Review the START option for the weight comparison between an old route and a newly calculated route before a path switch is attempted.
