Master Index

The master index resides in the index file data sets and contains the following types of records:

• Master control record (MCR)

  The MCR contains the control information for CA View, including the initialization parameters that have been selected. There is only one MCR.

• Tape control record (TCR)

  The TCR identifies the tape archival and tape duplex data sets. Each tape volume has one TCR.

• Group control record (GCR)

  The GCR describes the characteristics of each SYSOUT group that is archived. Each SYSOUT group has one GCR.

• User attribute control record (UCR)

  The UCR describes the attributes for the online users (for example, PF key definitions). Each attribute for each user has one UCR.

• Online member control record (OCR)

  The OCR describes the panels, messages, and skeleton JCL members loaded from the online library. Each panel, message, and skeleton JCL member has one OCR.

• Expanded retention control record (PCR)

  The PCR contains the control information for the Expanded Retention Option (formerly known as the Permanent Archival Option or PAO). The only PCR is present if the Expanded Retention Option is installed.

• View control record (VCR)

  The VCR contains a logical view definition. Each logical view defined has one VCR.

• Alternate index control record (ACR)

  The ACR consists of an index of SYSOUT IDs within a generation number. The CA View database has many ACRs.

Mapping macros for the records (SARMCR, SARTCR, SARGCR, SARUCR, SAROCR, SARVCR, SARPCR and SARACR) and a COBOL copy book defining the records (SARCBREC) are provided in CAI.CVDEMAC.
