What is Dbrm library?

The DBRM output contains the embedded SQL statements and host variable information extracted from the source program, information that identifies the program, and ties the DBRM to the translated source statements. It becomes the input to the DB2® bind process.

What is Plan package and Dbrm?

In DBRM, package and plan combination, the DBRM is first binded to a package. These packages are the DB2 optimized version of SQL queries but they are not executable by DB2. There is one package for every DBRM (one to one relationship). The package is then binded to a plan.

How do you create a Dbrm?

To have your program use static SQL, you must create a DBRM (database request module) and bind it to the SQL Option server you are going to run against. To create a DBRM, you need to compile your program with at least the following SQL Option preprocessor directives: DBRM=dbrm-name.

What is difference between plan and package?

packages are obtained by passing DBRMs through bindpackage. package ia not executable because it does not contain any acess path. plan is obtained by binding DBRMs r packages. plan is executable as it contains the acess path.

What is mainframe package?

A package contains control structures that Db2 uses when it runs SQL statements. An application plan relates an application process to a local instance of Db2 and specifies processing options. All control structures in a package are derived from the SQL statements that are embedded in a single source program.

What is the use of Dbrm?

DBRM stands for Database Request Module. This is the traditional DB2® serialized representation of the SQL statements in a program. For example, a program may be written in COBOL. This program will be preprocessed by DB2 to produce a DBRM that will be used to bind against a particular DB2 subsystem.

What is Dbrmlib in mainframe?

The DBRM module is nothing but SQL statements used inside the pgm. The library which have this is DBRMLIB. This DBRM needs to undergo a process called BIND to get a PLAN. This is because ;if one needs to execute a batch db2 program u have to have the load module of the program and the plan.

What is mainframe collection?

The collection is a group of packages using which we can segregate the DB2 packages belonging to the different applications.

What is static call and dynamic call in COBOL?

Static Call occurs when a program is compiled with the NODYNAM compiler option. A static called program is loaded into storage at compile time. Dynamic Call occurs when a program is compiled with the DYNAM and NODLL compiler option. A dynamic called program is loaded into storage at runtime.

What are the advantages of using a package?

It is a good practice to group related classes implemented by you so that a programmer can easily determine that the classes, interfaces, enumerations, and annotations are related. Since the package creates a new namespace there won’t be any name conflicts with names in other packages.
