SYDUMAX

The SYDUMAX system initialization parameter specifies the limit on the number of system dumps that can be taken per dump table entry.

SYDUMAX={999|number}
If this number is exceeded, subsequent system dumps for that particular entry will be suppressed. The SYDUMAX parameter applies for new or added system dump codes. It does not override the limit on the number of system dumps for existing dump table entries.
number
A number in the range 0 through 999. The default, 999, enables an unlimited number of dumps to be taken.
