| I am trying to determine the actual size or reasonably close of a dsn in tracks and/or cylinders with information from DCOLLECT. Looking at the DCDALLSP & DCDUSESP, is there some calculation that can be used? The storage is MOD29. I'm trying to figure out if I force migrate the DSN, how many tracks/cylinders it occupies. |

| 3.4 would be the most accurate information as the dataset is still on DASD |

| Have you searched the forum? There was a discussion of DCOLLECT data in the last few weeks. |

A DSN can never be more than 44 bytes.
A data set can be considerably larger, of course. |

This is so funny.
Do a google on DCDALLSP or DCDUSESP and ibm will give you all info.

Ah, but think of the fun/adventure if a dataset could only be 44 bytes. . .  |

I'm trying to relate either the DCDALLSB & DCDUSESP for a dsn back to what I see on 3.4. Fro example, I have a dsn on 3.4 shows 3015 tracks, 99% used. The DCDALLSP = 166838 & DCDUSESP = 166783. The storage device is 3390, MOD27.
Can't seem to come up with a calculation close to it. Any suggestions??? |

Check the maximum per track capacity (in bytes) on this model, might be around 56/57K.

| 3015 times 56664 / 1024 and round up |
