    High Performance Image Copy provides a new keyword FALLBACK=.
    This enhancement is for FITS MR0216094120.
    
    IMS HP Image Copy provides the new function FALLBACK that IMS HP
    Image Copy switches to the concurrent image copy process
    internally and creates image copy data set when IMS HP Image
    Copy can not get the read only exclusive authorization of the
    input database for the batch image copy process. FALLBACK
    process is effective when the requested function is Batch Image
    Copy with DBRC=Y.
    
    Restrictions of FALLBACK
    1. The process is not switched to the concurrent image copy
       process internally when the input database has one of
       following conditions:
       - Database that is not registered in the DBRC RECON data
         sets
       - Non-Recoverable database
       - The data set organization is VSAM KSDS if using
         FASTIC=(,COPY) or FASTIC=(,FDUMP) processing of the
         Advance Image Copy Services
       - If using FASTIC=(,DUMP) processing of the Advance Image
         Copy Services, the data set organization is VSAM KSDS that
         does not satisfy both of the following conditions:
         - SMS-managed data set
         - BWO(TYPEIMS) parameter is not specified on AMS DEFINE or
           ALTER for the data set.
    
    2. FALLBACK=Y is not effective when one of following keywords
       are specified:
       - DBRC=N
       - TOIAUTO=Y
       - TOIAUTO_Q=Y
    
    3. FALLBACK=Y is not effective following conditions:
       - The data set organization is VSAM KSDS and process is
         running with CIC_KSDS=N and FASTIC=N.
       - The input database is index and BYPDBAUTH=Y is specified.
    
    4. When the FALLBACK=Y is effective, following HD Pointer
       Checker options are ignored and corresponding reports are
       not generated:
       - HOMECHK keyword
       - Operands of HDPC keyword
         - DBDIST
         - DEPDIST
         - CHAINDIST
         - COMPFACT
    
    This APAR also fixes the following problems:
    1. IMS HP Image Copy prints the message FABJ3900E without the
       variable text data.
    
       The cause of misjudge is that the message which has no
       variable text data has been printed before printing the
       current message that has some variable text data. In this
       conditions, IMS HP Image Copy misjudges as the current
       message has no variable text data.
    
    2. Image Copy function terminates with ABEND S30A ( ABEND30A )
       when some error occurs before creating an image copy data
       set.
    
       During the error termination process, IMS HP Image Copy
       mishandles the condition and tries to issue unnecessary
       FREEPOOL macro.
       So, the FREEPOOL macro fails with unexpected ABEND S30A.
       This APAR prevents IMS HP Image Copy from issuing unnecessary
       FREEPOOL macro.
