SYS1.PARMLIB changes

z/OS TSO/E Customization
SA32-0976-00

To support a Session Manager environment, you may have to modify the following SYS1.PARMLIB members (or any installation-specified alternate members) to use specific types of terminals and improve performance:
  • For VTAM® - TSOKEY00
Two defaults in member TSOKEY00 are:
  • SCRSIZE - 480
  • BUFRSIZE - 132
Note:
  1. Figure 1. Recommendations
  2. Increase SCRSIZE to correspond to the type of terminals installed. For example, specify 3440 for a 3278 Model 4
  3. Increase BUFRSIZE to 1000 or greater. Although the buffer size is not critical, a larger size should improve performance.
