The MFA installation process references a missing card image PDS file that can cause the MFAAS task to fail the first time it runs.
You should define this file, by creating under TSO or by submitting JCL. For example:
//DEFVCTL JOB (MFA),MSGCLASS=A,CLASS=A,MSGLEVEL=1 //* //* Define Data Connect VSAM mapping control //* // EXEC PGM=IEFBR14 // MFAVCTL DD DSN=<hlq>.MFAVCTL, // UNIT=3390, // VOL=SER=volser, // DCB=(RECFM=FB,LRECL=80,BLKSIZE=6160), // SPACE=(CYL,(1,1,25),RLSE),DISP=(,CATLG,DELETE)
You must assign an appropriate high-level qualifier and select the unit and volume names for where this file will reside. In addition, each site may assign storage class options which comply with their data centre's standards.
