Problem summary

• ****************************************************************
  * USERS AFFECTED: All users of DB2 UDB for z/OS Version 9      *
  *                 ODBC/CLI and DB2 10 for z/OS ODBC/CLI.       *
  ****************************************************************
  * PROBLEM DESCRIPTION: ODBC applications running with external *
  *                      contexts may experience excess          *
  *                      DSN3201I messages being reported        *
  *                      causing storage leaks in DB2.           *
  ****************************************************************
  * RECOMMENDATION:                                              *
  ****************************************************************
  ODBC application running with MVSATTACHTYPE=RRSAF and
  MULTICONTEXT=0 can use the z/OS Resource Recovery Services (RRS)
  to create and manage its own RRS private contexts outside of
  DB2 ODBC.  All connection handles allocated under a RRS private
  context share a single DB2 thread which must be terminated
  when the last connection handle in the context is deallocated.
  However, if the DB2 thread is not terminated, this will result
  in DSN3201I message being issued when the application ends.
  

Problem conclusion

• Code has been modified to terminate attachment to DB2 if the
  connection handle being deallocated is the last connection in
  the RRS context for the current task.
