DSCOUNT start option

Read syntax diagramSkip visual syntax diagramDSCOUNT=1DSCOUNT=number_of_buffers

Specifies the number of output PIU chains to be saved as historical data for the session. If a 3270 protocol violation is detected, these PIU chains will be written to GTF trace for later problem determination. The larger the number of saved chains, the better the chances of isolating the specific cause of the reported violation, but at the cost of higher memory utilization. These buffers are stored in 64-bit memory.

Modify the DSCOUNT value by using the MODIFY VTAM®OPTS command while VTAM is running. The modification affects only sessions that are established after the modification is complete.
