The name of the Collection is specified by the PACKAGE parameter. This option allows EXPLAIN to be run when the authorization ID of the bind or rebind process does not have the privilege to execute statements in the package. If the command that specifies EXPLAIN (ONLY) refers to a package and version that already exists, the existing package is not dropped or replaced, even if ACTION (REPLACE) is specified. The process that builds access paths to the DB2 table is known as bind.

16. What is DB2. DB2 is a Database Management System for the MVS Operating System where, DB2 is … There are many parameters and values that must be chosen from and specified when you bind a DB2 application program. With so many options the whole process can be extremely confusing – especially if you don’t BIND on a daily basis. And even if you do, some of the options still might be confusing if you rarely have to change them. The DBRM is then bound into a PLAN that is accessed by a LOAD module at run time to obtain the correct DB/2 access paths for the SQL statements it contains.

The COBOL-DB2 program preprocessed by DB2 to produce a DBRM that will be used to bind against a particular DB2 subsystem. The Db2 system uses the DBRM to optimize application program interaction.

databasobjekt som refererats till i en SQL-sats vid det tillfälle då explain kördes The bind process inserts that information into the table owner.PLAN_TABLE. Owner can be the authorization ID of the owner of the plan or package. Alternatively, the authorization ID of the owner of the plan or package can have an alias as owner.PLAN_TABLE that points to the base table, PLAN_TABLE. 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.
or intermediate packages can be created by bind package and then inturn these packages can be fed to bind plan to get a plan. To execute a db2 program …
This is where BIND comes in. BIND is sort of like a compiler for the embedded SQL code, and the output of the "compile" is a package.

The COBOL-DB2 program preprocessed by DB2 to produce a DBRM that will be used to bind against a particular DB2 subsystem. The Db2 system uses the DBRM to optimize application program interaction. Q4)Explain what a plan is? A4)Plan is a DB2 object (produced during the bind process) that associates one or more database request modules with a plan name.

Explain the steps for db2-cobol's execution process if both are db2 -cobol programs (bind program) along with one dbrmlib which is having a dsn name. The main problem is that What are the changes affected in 'db2bind' while I am binding both the db2-cobol programs. (Interestingly, DB2 BIND sometimes generates instructions for more than one path.) This process is called optimization, and it's repeated for each SQL statement in the DBRM until all access paths are decided and the run-time instructions are created for each.
