What is bind process in DB2?
BIND – BIND is the process to find the optimized access path to retrieve the data from the DB2 for the SQLs coded in the program. BIND takes DBRM as input and generates the optimized access path with the help of an optimizer that considers the below factors.
What is bind process in mainframe?
STEP 4 – DB2 BIND The bind process reads the DBRM that was created in the precompile and prepares an access path to the data. This access path, along with the consistency token, is stored in the DB2 catalog as a Package. Every Package is bound into a Package List, or Collection.
What is BIND package and plan in DB2?
BIND PACKAGE subcommand allows you to bind DBRMs individually. It gives you the ability to test different versions of an application without extensive rebinding. BIND PLAN establishes the relationship between DB2 and all DBRMs or packages in that plan.
What happens in BIND step in a DB2 program?
