What is Plan bind in Db2?
Although the BIND PLAN command accepts the MEMBER option, the MEMBER option is deprecated. Use it only when you cannot run BIND PACKAGE to bind DBRMs into packages explicitly. When you specify MEMBER, Db2 binds the DBRMs into packages, and includes those packages in a package list for the specified plan.
