- Step5: DB2 BIND.
- Step6: Execute/Run the Program.
What is compilation in DB2?
The Db2 precompiler scans a program and copies all of the SQL statements and host variable information into a DBRM (database request module). The precompiler also returns source code that has been modified so that the SQL statements do not cause errors when you compile the program.
How do you compile a COBOL program?
COBOL HELLO WORLD Program
- Step1: Code the COBOL Program.
- Step2: Prepare the COMPILE JCL to compile and Link Edit the COBOL Program.
- Step3: Prepare the RUN JCL to execute the COBOL Program.
What is the COBOL DB2 CICS program compilation process?
CICS-DB2-COBOL Program – Compilation The program is first passed to CICS Translator and the translator will convert all the CICS commands to COBOL call statements and this modified source is passed to COBOL compiler.
What is the output of pre compilation process?
DB2 Precompilation Process by using DB2 precompiler. It generates two outputs (i.e. Modified Source code and Database Request Module (DBRM)). Modified source code is a compiled and link-edit like a simple COBOL program because it does not have any SQL statements.
Which is the correct sequence to prepare DB2 COBOL program?
About this task
| DB2 version and program language | Step 1 (SQL statement processing) | Step 2 (CICS command translation) |
|---|---|---|
| DB2 V7 (or later) and COBOL | Language compiler that supports integrated CICS translator and SQL statement coprocessor | |
| DB2 V7 (or later) and other languages | DB2 precompiler | CICS-supplied separate translator |
What is Sqlca in DB2?
SQLCA stands for SQL-Communication Area. It is a medium through which DB2 can communicate with the COBOL program. In a typical COBOL-DB2 program, there are many SQL statements used. The main purpose of SQLCA is to inform the COBOL program about the status and other details of the most recently executed SQL query.

- Hi,In Endevor SCLs are there for every action related to version control of the programs.For recompiling a program we add a SCL to generate program(s).simply submit this SCL give a JOB name.if any abend is there the details can be viewed on SYSVIEW option.regards,pradeep.
What happens in link edit of a Cobol CICS Db2 program?
The linkage editor links the object program with any subprograms called from it and also creates the executable component for the program. The linkage editor creating an executable component for the program called a load module.
How to precompile a cobol-db2 program?
How to precompile a COBOL-DB2 program? Precompilation is the process through which the SQL statements used in the COBOL-DB2 program are replaced by appropriate COBOL calls. The precompilation is necessary before the actual compilation because the COBOL compiler cannot recognize the DB2 SQL statements and will throw errors due to them.
What is DB2 precompilation in DB2?
DB2 Database Big Data Analytics Precompilation is the process through which the SQL statements used in the COBOL-DB2 program are replaced by appropriate COBOL calls. The precompilation is necessary before the actual compilation because the COBOL compiler cannot recognize the DB2 SQL statements and will throw errors due to them.
What is the pre-compilation step in COBOL?
In the pre-compilation step all the SQL statements which are present in the source program are replaced by corresponding COBOL calls. All the SQL statements are taken in an object known as database resource module (DBRM) and passed on to the BIND step.
What are the steps involved in compilation of a cobol-db2 program?
Steps involved in compilation of a COBOL-DB2 program. DB2 Database Big Data Analytics. To prepare a COBOL-DB2 program for execution, we have to go through certain steps. These steps include pre-compilation – compilation – binding – linkediting. The pre-compilation is done using the utility DSNHPC.
