What is Plan bind in DB2?
If you specify one or more DBRMs to include in the plan (by using the MEMBER option of BIND PLAN), Db2 automatically binds those DBRMs into packages and then binds those packages into the plan. The plan contains information about the designated packages and about the data that the application programs intend to use.
What is the difference between BIND plan and bind package?
Plans are created by the BIND command. The plan is stored in the DB2 directory and accessed when its program is run. Information about the plan is stored in the DB2 catalog. A package is a single, bound DBRM with optimized access paths.
How do I bind a DB2 program?

What happens in BIND step in a DB2 program?

In order to BIND the SQL into an executable “package”, the BIND process attaches to DB2 and does a few things: Verifies that the current AuthID is authorized to perform a bind. Checks the syntax of your SQL, with help from the data in the DB2 catalog. Finally, and most importantly, the bind will optimize your SQL.
