Order of Media Access

When a user selects a report for browsing (selection code S in an online report selection list), the following list is the order of media access:

• If the report is on the CA View DASD database (including a TEMP DASD copy that was loaded back to disk), it is accessed from DASD.
• If the report is not on DASD but is on optical disk, it is accessed from optical disk.
• If the report is not on DASD or optical disk, the expanded access server accesses it.
• If the report is not on DASD or optical disk, and the expanded access server is not active, the tape is mounted and the report is loaded to disk, assuming there is mount authority.

  LOAD jobs execute on the system with the primary server; otherwise, all the data is transmitted across systems using XCF or LSERV.
