ensure that this option is the same as that used in the previous run of the
Detector (for which affinity data is to be restored).
v Size of dataspace
The size that you want to use for the data space to store the affinity data
collected. The size of the data space is fixed for a run of the Detector. For
information about estimating the size of the data space, see “Estimating the size
of the MVS data space and VSAM files” on page 21.
If the data space becomes full when running, the Detector terminates with abend
code AUXB.
If you are saving affinity data, there may be a delay from the time the data space
became full until the time the Detector actually terminated.
v Transid prefix
The prefix (zero through three characters) of the transactions for which you want
to gather affinity data, If you do not specify any characters, affinity data is
collected for all transactions. If you specify a valid prefix (for example, AB_),
affinity data is collected for only those transactions with identifiers starting with
the prefix.
Leading and trailing blanks are ignored, but embedded blanks are treated as an
error.
2 Detect affinity types
Whether or not the Detector is to detect the types of affinities listed.
For more information about restrictions affecting the detection of affinity commands,
see “The Detector component” on page 12 and “Appendix A. Details of what is
detected” on page 65.
3 Transaction system
WAIT commands are listed as transaction-system affinities, because only half the
affinity can be detected. (The other half, an MVS POST command or hand posting,
cannot be detected.) You should investigate such affinities further, and, if needed,
change the output from the Reporter to create basic affinity transaction groups for
them.
4 Last update by <userid>
The date and time when the options were last updated, and the userid of the user
who made the updates.
The date is displayed in the format defined by the DATFORM system initialization
parameter.
