 |
|
| I hope this is the right forum, if not please direct me to where this should be placed. I have a SMF monthly dsn that gets modded to every day, well I'm trying to run the SCRTTOOL report for IBM & the 20th volume of the dsn is bad, the tape cannot be read. How can I gener or whatever the the dsn to bypass the bad volume?? Any help will be GREATLY appreciated! |

What are the DCBs? I hope the records are not still in spanned format (RECFM=VBS)?
If not spanned, you can copy the file coding all volume serial numbers except the 20th and use the new output file. If you get an error about volumes out of sequence, you may need to copy in two steps (1 thru 19 then 21 thru end) and MOD onto the output. You can use the VOL=(,,21) parameter to start processing on the 21st volume.
If still spanned format, the last block on volume 19 might have had a record continuing onto volume 20. This will probably give logical data errors when you drop volume 20.

They are spanned records. I did some digging through DFSORT's customization manual & it says that you can override the SPANINC parm with the following code:
| Code: |
//DFSPARM DD *
OPTION SPANINC=RC0
/*
|
I'm trying this now & will update with results. |

Setting the SPANINC=RC0 worked. Output from the job is below:
ICE197I 0 ONE OR MORE INCOMPLETE SPANNED RECORDS DETECTED AND ELIMINATED - RC=0
ICE055I 0 INSERT 0, DELETE 0
ICE054I 0 RECORDS - IN: 98124085, OUT: 98124085
Although I can't figure out how we can have the same record count for in & out & have spanned record(s) deleted. |

DFSORT's SPANINC=RC0 option eliminates incomplete spanned record segments from the input data set. Basically it skips over any segments that don't comprise a complete record. The IN count only reflects full (good) records, not incomplete segments. So the OUT count (of the good records) is equal to the IN count (of the good records). Including the bad segments in the IN count would be problematical since they are NOT complete records. For example, DFSORT might eliminate a first and middle segment that doesn't have a last segment - it wouldn't make sense to count the first and middle segment as input records.
