The DIFFERENCE between SPECIFYING DISP=OLD and DISP=SHR for a DATASET is that,
DISP=OLD: It reads data from beginning of dataset. But incase if you TRY to modify or write, then it will overwrite on existing data. i.e old data is lost
DISP=SHR: Its read-only file. In this, multiple USER can share the data

JCL RECOGNIZES the program to be executed, the INPUTS that are required and location of the input/output and informs the OPERATING System through Job CONTROL Statements.

JCL recognizes the program to be executed, the inputs that are required and location of the input/output and informs the Operating System through Job control Statements.

The TYPES of JOB control STATEMENTS are

• JOB – to identify the Job
• DD – to supply the I/O files needed for the EXECUTION of the PROGRAM
• EXEC – to identify which program has to be executed

The types of job control statements are

• It is used for the deleting CREATING, the Data Sets, GDG’S and VSAM CLUSTERS.
• It is used for comparing the files and PDS members
• It is used for compiling and executing the programs which INCLUDES BATCH programs as well
• It is used for merging and sorting on file data

JCL stands for Job Control Language. It is the command language of Multiple Virtual STORAGE (MVS). It is the normally used in OPERATING System in the IBM MAINFRAME computers.

SHAREOPTS is a parameter in the DEFINE and SPECIFIES how an object can be shared among users. It is coded as SHAREOPTS(a B), where a is the cross region share OPTION ie how TWO or more jobs on a single system can share the file, while b is the cross system share option ie how two or more jobs on different MVSes can share the file. Usual value is (2 3).

No. Because you cannot insert records in an ESDS, also when you rewrite a record, it MUST be of the same LENGTH. Thus PUTTING any value for freespace does not make any sense.

CI size should be BASED on record length, type of processing. Usually CI is 4K.If record length is larger(>1K), CHOSE 6K or 8K. FREESPACE should be large if more number of INSERTIONS are envisaged. Usual values are (20 20) when heavy updates are expected. CI size can be calculated.

Coded in the DEFINE as FREESPACE(CI ca) where ci is the PERCENTAGE of each control interval to be LEFT free for insertions, ca is the percentage of control intervals in each control area to be left empty.

Control Interval is analogous to a physical BLOCK for QSAM files. It is the unit of i/o. Must be between 512 bytes to 32 k. Usually either 2K or 4K. A larger control interval INCREASES performance for sequential processing while the reverse is true for random access. Under CICS when a record is locked, the entire CI gets locked.
Control area is a group of control intervals. CA is used during allocation. CA size is calculated based on the allocation type (cyl, tracks or records) and can be max of 1 CYLINDER
