This parameter indicates the initial number of non-threaded, idle db2fmp processes that are created in the db2fmp pool at START DBM time.
Setting this parameter will reduce the initial startup time for running non-threadsafe C and Cobol routines. This parameter is ignored if keepfenced is not specified.
It is much more important to set fenced_pool to an appropriate size for your system than to start up a number of db2fmp processes at START DBM time.
In previous versions, this parameter was known as num_initdaris.
