Answer / sneha
Plan is an access path for your program to access the DB2 table. During precompilation process, the SQL queries are converted into executable statements and stored in DBRM (Database Request Module). This DBRM will have a consistency token. During the bind step, this DBRM will be read and a plan will be produced. Few important parameters we include in Bind job is ISOLATION LEVEL ( how one transaction needs to be separated from another transaction which does some data modification on the table), QUALIFIER etc.
