Answer / s
Packages are single bound DBRMs which contains SQL
statements of a single application program or subroutine.
Before the application program can be executed, you need to
bind a plan. The plan can be bound with DBRM members and/or
Package list. Without the use of packages, if there is any
change made to the program, even if there are no changes to
the SQL, the whole plan need to bound which cause
unavailabilty of the plan and it is resource intensive
since all the unrelated DBRMs are also need to be bound.
With the use of packages, only the package need to be bound
without the need to bind the plan. Also bind parameters can
be specified at package level rather than plan level

First u need to know the concept precompliation and
compliation process of db2 cobol program...
the maina dvange of pakage is, supose u have cobol db2
program, this prgoram is using 4 sub programs. if any one
of the sub programs undergoes changes u need to precompile
the main program. this can avoided by using the pakage
concept.
so u need to create one pakage for on sub program. if any
sub programs undergoes any change, u need to compile only
sub program.
Filnally one program will have one pakage and one DBRM lib.

Consider that a package is bound into 2 different collections and the PKLIST option specifies both the collections.
