Condense Files

Condense Files

Condense files are created as a part of the condense process in the condense job.
They contain the change data for the active registrations found by the condense job during initialization.
The EXT_CAPT_MASK and CONDF_FULL_FILE_CTL parameters in the CAPTPARM file determine the names of these data sets.
The following table lists the data set type and the format of the data set name for each type of condense file:
Condense File Type
Data Set Type
Format of the Data Set Name
Partial
Variable-blocked sequential
The data set name has the following format:
hlq
.CND.CP
yymmdd
.T
hhmmssn
Where:
  • hlq
    is an EXT_CAPT_MASK value
  • yymmdd
    is a date
  • hhmmss
    is a time
  • n
    is a sequence number, starting at 1, to establish a unique ID
Full
VSAM KSDS
The cluster data set name has the following format:
hlq
.CND.CF
yymmdd
.T
hhmmssn
Where:
  • hlq
    is an EXT_CAPT_MASK value
  • yymmdd
    is a date
  • hhmmss
    is a time
  • n
    is a sequence number, starting at 1, to establish a unique ID
The PowerExchange Listener or a netport job uses the CAPX access method to read condense files. You can use the PowerExchange Navigator to view the data in closed condense files. Run a database row test against the extraction map in the appropriate extraction group.
You can use a variety of methods, including PowerCenter sessions and workflows, to extract and process the condense change data.
