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.

Although the problem with the older version of UNDEL2 was diagnosed
and then corrected in a newer version, that does not eliminate the fact
that some SQL DELETE may in fact cause deleted rows to be unrecoverable
using a utility using the SAVOBJ to access the data indirectly. In fact
since the ability to recover the data is due entirely to implementation
details, since implementation details may change, one should not expect
that method of recovering rows to be available; e.g. just as currently
the ability to recover varlen data is already effectively not [or is in
some cases im]possible.
The best bet is to simply journal all sufficiently important database
files, so that in the event some accidental deletion occurs, the data
can be recovered without having to rely on /tricks/ versus supported
/methods/ against the data. If the file is not important, nor should be
the ability to recover from such an error. So as not to require
explicit journaling for a particular library, there is the option to
either create the QDFTJRN *DTAARA [look up details using QDFTJRN as
search token] into libraries where important files will reside, or use
SQL to create the files using CREATE TABLE and create important files in
an SQL SCHEMA.
