This section presents you various set of Mock Tests related to JCL Framework. You can download these sample mock tests at your local machine and solve offline at your convenience. Every mock test is supplied with a mock test key to let you verify the final score and grade yourself.
Identifiers are two slashes (//) starting from column number 1. All JCL statements starts with identifiers except for two exceptions - For a delimiter statement, /* starting in col 1 and for a comment statement , //* starting at col 1.
Q 6 - Which of these is not a valid operation code?
When the job reaches its highest priority, it is taken up for execution from the job queue. The JCL is read from the SPOOL, the program is executed and the output is redirected to the corresponding output destination as specified in the JCL.
When the job is complete, the allocated resources and the JES SPOOL space is released. In order to store the job log, we need to copy the job log to another dataset before it is released from the SPOOL.
Q 15 - What operation is performed by EXEC statement?
Specifies the PROC/Program to be executed. In the above example, a SORT program is being executed (i.e., sorting the input data in a particular order).
Q 16 - What operation is performed by JOB statement?
JCL is terminated by a null statement which is optional. For a null statement code only // starting from column 1. All the lines after this will not be executed.
Q 19 - What is the purpose of coding CLASS parameter in job statement?
Based on the time duration and the number of resources required by the job, companies assign different job classes. These can be visualized as individual schedulers used by the OS to receive the jobs. Placing the jobs in the right scheduler will aid in easy execution of the jobs. Some companies have different classes for jobs in test and production environment. Valid values for CLASS parameter are A to Z characters and 0 to 9 numeric (of length 1). Following is the syntax: CLASS=0 to 9 | A to Z
Q 20 - What is the purpose of coding MSGCLASS parameter in job statement?
To specify the priority of the job within a job class. If this parameter is not specified, then the job is added to the end of the queue in the specified CLASS. Syntax : PRTY=N
