In this COBOL DB2 Compilation Process tutorial, you'll learn the step by step process to compile COBOL DB2 program (i.e. db2 compilation steps) on the mainframe. DB2 precompilation process includes COBOL DB2 precompiler or DB2 SQL coprocessor. You'll also learn the basic difference between DB2 precompiler and DB2 SQL statement coprocessor. How to prepare COBOL-DB2 program for execution. After completing this tutorial you'll able to answer all interview question related to COBOL-Db2 completion process, DB2 Precompiler, DB2 optimiser, DB2 bind process, DBRM (database request module) DB2 package and DB2 plan. Let's get started with today's COBOL DB2 Compilation Tutorial. ► Index Details ◄ 0:00 Welcome to COBOL DB2 Program Compilation Tutorial. 0:36 COBOL DB2 Compilation Tutorial Agenda. 1:19 COBOL DB2 Program Overview. 1:53 Why you need DB2 precompiler?. 2:28 DB2 Precompiler or SQL Coprocessor function. 3:19 COBOL DB2 compilation process flow diagram. 4:21 DB2 Bind Process (DBRM / Bind Package / Bind Plan). 6:04 DB2 SQL Statement Coprocessor. 7:37 COBOL DB2 Program Performace Tips. 8:02 COBOL DB2 Compilation Process Tutorial End. After completing the COBOL DB2 compilation process in mainframe you will have a good understanding of 'Preparing an application to run on mainframe z/OS' systems. Let's begin today's mainframe tutorial. ►COBOL DB2 Compilation process: COBOL-DB2 program compilation process is similar to the standalone COBOL program compilation. But before you compile a program that accesses DB2 data, you must run the DB2 precompiler to translate the SQL statements into COBOL statements that invoke DB2 functions. ►What is a DB2 precompiler? DB2 Precompiling: The DB2 precompiler prepares the source program for the compilation process. It generates the DBRM and modified source code. ► What is DB2 coprocessor? The Db2 coprocessor performs Db2 precompiler functions at compile time. When the compiler encounters SQL statements in the source program, it interfaces with the DB2 coprocessor. All text between EXEC SQL and END-EXEC statements is passed to the coprocessor. The coprocessor takes appropriate actions for the SQL statements and indicates to the compiler which native COBOL statements to generate for them DB2 precompiler and DB2 coprocessor perform the following actions: ►Replaces the SQL statements in the source programs with calls to DB2 language interface modules. ►Creates a database request module (DBRM), which communicates your SQL requests to DB2 during the binding process. Before the load module can be executed, though, DB2 must bind the program. You can bind a program directly into an application plan, or into a package and then into a plan. ►Subscribe to @Topictrick ​ & Don't forget to press THE BELL ICON to never miss any updates.
