The internal search function is temporarily non-functional. The current search engine is no longer viable and we are researching alternatives.
As a stop gap measure, we are using Google's custom search engine service.
If you know of an easy to use, open source, search engine ... please contact support@midrange.com.
The QSYS2.SYSTABLES excludes both Multi-Format logical files, SQL
INDEX, and program described files. TABLE_TYPE='P' will give PF which
may have multiple members; 'T' will give SQL TABLE; 'M' for MQT -- 'A',
'L', and 'V' are presumably undesirable. Using that file avoids coding
to the API to get the desired information. If the file is 'P' then the
multiple members may still be an issue for an application; SYSPSTAT will
find the member, but not efficiently.

The JDBC excludes some files for the same reason as SYSTABLES; i.e.
when the file is not considered as having /relational/ capabilities, due
to either being program described for multiple formats. In DSPFD of
SYSTABLES, it is the inclusive test DBXREL='Y'
