Subject: Determine level of fragmentation in VTOCIX?
Is there a way to determine if and how much a VTOCIX is fragmented. Way back
when (when disk wasn't quite so cheap), we standardized on parking the
VTOCIX in the 14 tracks left in the 1st cylinder, and for a Mod-3, VTOC of
105 tracks (7CYL) immediately following, and usually a 2 CYL VVDS right
after that. Most of my SMS managed application disks still follow this. And
it worked well for many years.
But, during high volumes of SMTP activity, I have begun to get:
IEC603I VTOC ERRORS MAY EXIST ON C465,PPRD22,8,027
IEC331I 042-002(0812041B),SMTP ,SMTP ,RNAM,IGG0CLH2

SMTP is playing a dataset rename game - SMTP.TEMP.NOTE to SMTP.CONNnnn.NOTE
(a 3 character length increase)
SMTP then kindly sends a blank email to the recipient which then gets
reported as suspicious :)
I don't remember how we reached the numbers we used, but looking at the info
the ICKDSF manual, the 14 track index should be large enough for the 5250
datasets possible with a 105 track VTOC. I an wondering if I can REFORMAT
REFVTOC EXTINDEX(14) and get refreshed, unfragmented VTOCIX.
