The FOCUS processes a report request with
the following steps:
It locates the
Master File for the Adabas file. The file name in the report request
is the same as the z/OS PDS member name.
It detects the SUFFIX
attribute, ADBSINX, in the Master File. Since this value indicates
that the data resides in an Adabas file, it passes control to the
adapter.
The adapter locates
the corresponding Access File and uses the information contained
in both the Master and Access Files to generate the Adabas direct
calls required by the report request. It passes these direct calls
to the Adabas DBMS.
The adapter retrieves the data generated by the Adabas DBMS
and returns control to the server. For some operations, the server
may perform additional processing on the returned data.
