Data Structures

The Event Capture data sets can be thought of as data stores. These data sets can be shared among multiple systems, or unique data sets can be created for each system.

The Event Capture function uses the following three different types of data sets:

• The Capture Library data set

  The Capture library data set (CAPLIB) contains members whose content describes the data the specific event is to capture. Each event member is a simple list of SYSVIEW display commands and each member in the data set is a separate event. Individual event members can be combined to make larger sets of events using the following parmlib keyword statements:

  “)INCLUDE member”
  

  Sample event members are supplied in the sysview.CNM4BCAP data set that comes with CA SYSVIEW.

• The Capture Index data set

  One or more index data sets are used to catalog a list of captured events. A common or shared index data set can be used for all systems when the data set is allocated on shared DASD. A separate index data set can also be used for each system. Index data sets are defined as a VSAM KSDS data set. If separate index data sets are used, the high-level qualifier specified for the index data sets should contain the system name. You can easily specify the high-level qualifier using the &SYSNAME symbolic parameter.

• The Capture Event data set

  The Event data sets are used to store the captured data for each event. One event is stored per data set. Specify a high-level qualifier for the Event data sets. Verify that the high-level qualifier contains a maximum of 29 characters to provide enough room to append the date and time qualifiers.

  Event data set names have the format:

  sysview.capture.hlq.Dyymmdd.Thhmmss
  

  sysview.capture.hlq

  Is specified in the System Configuration Options member using the Dsn-System-CAPDATA-HLQ keyword.

  D

  Indicates Date, and yymmdd specifies the year, month, and day.

  T

  Indicates Time, and hhmmss specifies hour, minute, and second.

  Important: Understand that a large amount of Event data sets can be created. Set the default space allocation parameters for the Event data sets in the parmlib member CAPTURE, which is found in the sysview.CNM4BPRM data set.
