The next value will be 0 and the sequence will never use the values 101 to 105.
The next value will be 101 to ensure uniqueness between existing and newly generated sequence values.
Previously cached values are retained by DB2, and after the restart, will be used for values 101 to 105.
The next value will be 0 and DB2 will not ensure uniqueness between existing and newly generated values.
