Bill, In my first e-mail, I displayed the dsn the following way: ISPF 3.4 ZWA6PWG.ICO9999D.DMSC.D2012087.T130018 Next, I typed I besided the dsn Then it displayed me the dsn stats.

The display you show below only displays the first 3 extents, which have a total of 3*1074=3222 tracks, which is what your previous email said was the total of all tracks allocated. This display also shows a non-zero pointer to a F3 DSCB in which will be described up to 13 more extents of which your data set will have non-zero values in the first 9, for a grand total of 12*1074=12888 tracks. The last block pointer in the display below agrees with the number of tracks utilized in your previous email. It appears that for some reason the program that you used to display the data set attributes in your previous email ignored the F3 DSCB. Or perhaps you asked the system to tell you the data set attributes in your previous email at just the wrong millisecond when the system was also in the midst of updating the F1 DSCB. Possibly your display request read the F1, began formatting the display, then read the F1 again after formatting the number of tracks allocated but in between! your two reads of the F1 the system rewrote the F1 and changed the last block pointer field, then when your display request read the F1 again it displayed the non-zero last block pointer. Some code is perhaps not properly serializing on the VTOC accesses. Either way, you should get IBM involved in resolving this issue, assuming that IBM wrote the program that you used for your previous display.

I have never seen before where the current utilization >is larger than the allocation. I've never seen that either. Before attempting any correction, I would use IEHLIST to obtain a LISTVTOC FORMAT and a LISTVTOC DUMP for the data set. I wonder if ISPF is reporting the information correctly. If the LISTVTOC confirms the information that ISPF shows, I'd recommend calling the IBM support center. -- Tom Marchant ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
