The continuous data collection table creation user exit, CDCA, allows you
to create tables that are necessary to store data.
CDCA is called during the processing of the ZCDCO command with the CREATE
parameter specified.
Input
None.
Programming Considerations
- Any tables that you create must provide columns for CDC_KEY and
CDC_TIME. These pointers serve as common keys for the remaining data
and allow you to relate a row in one table to a row in another table.
- CDC_KEY is a pointer to a 9-character string that corresponds to the
8-character representation of the CPU ID plus the null character.
- CDC_TIME is a pointer to a 27-character string that corresponds to a
structured query language (SQL) time stamp.
- CDCA must be returned to the caller in the same state that it was on
entry.
Return Values
None.
