Remove 32768 limit to DSMAX

DSMAX field (DSMAX subsystem parameter)

The DSMAX subsystem parameter specifies the maximum number data sets that can be open at one time.

How DB2 enforces the limit depends on the DSMAX value:

• If the value is 32,768 or greater, new OPEN statements begin to fail with reason code 00C20113 when the DSMAX value is reached.

• If the value is less than 32,768, DB2 tries to keep the number of open data sets at or below the DSMAX value. However, new OPEN statements do not fail, unless the number of open data sets reaches 32,768. Instead, DB2 begins closing data sets to keep the number of open data sets at or below the DSMAX value.

If there is no technical reason why is there the limit set at 32,768.
