You will allocate 7 unique z/OS data set types

Edit and submit JCL JOB with the following modifications:

1. Modify DD operation DSORG parameter to allocate a sequential data set
2. Modify DD operation DSORG parameter to allocate a partitioned data set
3. Modify DD operation DSORG and DSNTYPE parameter to allocate a partitioned data set extended
4. Modify IDCAMS utility program DEFINE CLUSTER control statement to allocate a VSAM KSDS cluster
5. Modify IDCAMS utility program DEFINE CLUSTER control statement to allocate a VSAM ESDS cluster
6. Modify IDCAMS utility program DEFINE CLUSTER control statement to allocate a VSAM RRDS cluster
7. Modify IDCAMS utility program DEFINE CLUSTER control statement to allocate a VSAM LDS cluster

• z/OS disk storage space is allocated in 'extents'
    - An extent is a contiguous area on disk with an absolute starting and ending location
    - z/OS data sets have 1 primary extent
    - When the primary extent is full, then a secondary extent is automatically allocated
    - The number of secondary extents depends upon the type of data set
    - The size of a primary extent and subsequent secondary extents are determined by a SPACE attribute
  

  See References drop down Data Set Allocation and Disk Storage Summary

• z/OS stores data in a variety of organization types categorized as NON-VSAM and VSAM
  NON-VSAM includes
    1) Sequential
    2) PDS, Partitioned Data Set
    3) PDS/E, Partitioned Data Set/Extended
  VSAM includes
    1) KSDS, Key Sequences Data Set
    2) ESDS, Entry Sequenced Data Set
    3) RRDS, Relative Record Data Set
    4) LDS, Linear Data Set
• Unix file systems
    - Unix filesystem is a stream of bytes
    - Physical VSAM LDS formatted for Unix filesystem stream of byte processing
• Databases
    DB2 is a relational database
    DB2 data is stored in a VSAM LDS, formatted, and managed by DB2
    IMS Hierarchical DB uses special access method data sources which are excluded from the contest
• Data Set attribute syntax includes:
    LRECL, Record Length
    DSORG, Data Set Organization
      - PS Physical Sequential
      - PO Partitioned Organization
      - VS VSAM
    RECFM, Record Format
      - F Fixed Length Records
      - FB Fixed Length Blocked Records
      - V Variable Length Records
      - VB Variable Length Blocked Records
      - U Undefined Length Records

NOTE: All occurrences of &SYSUID. are automatically replaced by your ID when submitted.

Change all occurrences of the @ symbols with appropriate parameters to accomplish the following:

• &SYSUID..CH9.SEQ created as a sequential data set type
• &SYSUID..CH9.PDS created as a partitioned data set type
• &SYSUID..CH9.PDSE created as a partitioned data set extended type
• &SYSUID..CH9.KSDS created as a VSAM Key Sequenced Data Set type
• &SYSUID..CH9.ESDS created as a VSAM Entry Sequenced Data Set type
• &SYSUID..CH9.RRDS created as a VSAM Relative Record Data Set type
• &SYSUID..CH9.LDS created as a VSAM Linear Data Set type
