The 4 GB VSAM limit can be overcome with extended addressability. Here is the definition I used for V2R1 ServerPac, a ZFS that occupied an entire Mod 27. The key is data class, which is set in SMS for EA.

Good luck. > Another method would be "df" command. From unix prompt issue "df /your/directory" or "cd /your/directory" and then "df . " You'll get filesystem name = ZFS or HFS dataset name. Then look at dataset parameters. There are many factors which can limit growth: - number of extents - free space on the volume - multi-volume - candidate volumes availability - 4GB limit for VSAM -- Radoslaw Skorupka Lodz, Poland ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
