ABSTRACT OF PROBLEM
___________________
After applying APAR PQ32210, a DB010E system error may occur
when a DBSRT is performed on an input file which was opened with
the PARAM= option specifying a data level (Dx).
COMMENTS ON PROBLEM
___________________
A file was opened using PARAM= with a data level specified.
This was followed by a DBSRT that used that same file as the
input file. At the end of DBSRT processing, an internal DBCLS
NORELEASE was issued which forced the SW00SR block (specified in
PARAM=Dx) to be switched from the data level used by TPFDF to
the level specified when the file was opened. After the DBCLS,
the SW00SR block was not switched back to the level used by
TPFDF, which caused the next search for the SW00SR block to
fail. This might typically occur when a DBCLS is done on the
input file, and the result is a DB010E system error.
SOLUTION
________
The code to swap data levels when a user data level is specified
on an open command was moved from segment UWAD to segment UWBC.
Segment UWAU has also been updated to always check if the data
level should be appropriately swapped when the INPUT= or
INPUTREF= parameter is specified on a DBSRT command. Finally,
the DFLNK restricted use macro was updated to allow multiple
DFLNK SWAP calls within a single segment. By always swapping
the SW00SR block to the appropriate level, the DB010E system
error will not occur.

Migration Considerations
========================
The DATA= parameter should no longer be used by applications; it is
provided only for migration purposes. The PARAM=AUTO parameter should
be used instead.
