For the third question I think that a check of library or the WFH can help you too(see the xxxx but for the library depend of your installation):
| Code: |
//STEP010U EXEC PGM=DSNTIAUL
//STEPLIB DD DSN=DB2.DSNEXIT.xxxx,DISP=SHR
// DD DSN=DB2.DSNLOAD.xxxx,DISP=SHR
// DD DSN=DB2.RUNLIB.xxxx,DISP=SHR
....
//WFHxxxx DD DUMMY |
