DB2 BIND PRECOMPILE Process - DB2 SQL CODES -805 -818 DRONA SERIES DB2 DB2 Precompile-Compilation-Bind Process INTRODUCTION Static SQL - COBOL PRE-compile process For COBOL-Static SQL program, program needs to be precompiled before doing actual compilation of that program. Following are the 4 steps to compile a COBOL-DB2 program STEP 1 - DB2 PRECOMPILE Process The DB2 Precompile performs three functions.
First, it checks the SQL in the program for errors. Second, it adds working storage areas and source code compatible statements that are used to invoke DB2. One of the working storage areas contains a literal 'timestamp' called a consistency token. Finally, all of the SQL statements are extracted from the program source and placed into a member called the DataBase Request Module, or DBRM, which also contains the consistency token. STEP 2 -COMPILE The modified source from the precompile is then compiled.
The code is checked for errors, and a compiled version of the code is created. STEP 3 -LINK-EDIT The compiled code is link-edited along with statically called source language and DB2 run-time modules to create a Load Module. Imbedded in this module is the same consistency token that was generated in the precompile. If multiple DB2 programs are statically linked together, the resulting load module contains a consistency token for each one. 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. The name of the Collection is specified by the PACKAGE parameter.
See More On Tutorialspoint
A Collection is a group of Packages that are included in one or more Plans. The QUALIFIER parameter of the bind is used to direct the SQL to the specific set of DB2 objects (tables, views, aliases or synonyms) qualified by this name. EXECUTING COBOL-DB2 PROGRAM When COBOL-DB2 Program executes, the plan name must be specified. For online CICS programs, the plan name is specified by Tran ID in the Resource Control Table (RCT).
For a batch program, the plan name is specified in the SYSTSIN input DD. The packages for all DB2 programs executed under a Tran ID or batch job step must be included in collection bound into this plan. When the first SQL statement of each program is executed, DB2 searches the collections within the plan using the package name and consistency token from the load module. If an exact match is not found, a -805 SQLCODE is returned. Also visit.
