VTOC scan processing

Using the VTOC scan process you can complete the following actions:

  • Collect data in a master collection data set
  • Collect data in a user-specified collection data set
  • Filter data set collection
  • Save selection criteria
  • Apply saved selection criteria to another group of data sets
  • Execute in batch

The master collection data set is a continuously updated data set, which means that it is refreshed with each execution of a VTOC scan. When the MainView SRM Reporting component performs a collection against the master, the component first determines the volumes that qualify for the collection. All data set records from the qualifying volumes are then dropped from the master unless the reuse of data set statistical records is attempted. The volumes are then processed and new data set records are built and written to the master. This method of update allows you to split your collection into more manageable runs that are under your control.

The generated name of the master collection data set is the VSCAN_OINDX value, with .MASTER appended. The nonmasters are the VSCAN_OINDX value, with .SMVSCFxx appended and one of the following values:

  • Date and time
  • Value of OUTSUFFIX if specified in the SMVSCFxx member

Note

VSCAN_OINDX can be set to the same value in multiple instances of MainView SRM. This procedure allows you to run scans from multiple systems and merge the data into the master collection data set. The collection data set contents can be reported from any MainView SRM.

VTOC scan uses the master collection data set when you do not specify the collection data. You can choose a specific collection data set by using the SETSRM action command with the complete data set name, the SMVSCF xx filter name suffix, or a blank. A blank value uses the master collection data set. When you specify a filter name suffix, the Reporting component uses the most recent collection data set that was created from that filter member.

VTOC scan online reports execute against the records in the master collection data set. To apply different selection criteria to the master collection data set, you can use the following items:

  • Current VTOC Scan Data Set Statistics Entry view
  • Customized views
  • SETSRM command

To apply the same selection criteria to different collection data sets, you can select a different collection data set from the VTOC Scan Collection Data Set View or use the SETSRM command.
