Is this really so? When SMF reports a particular number of EXCPs, I believe it's really just counting blocks (SMF gurus feel free to chime in here). The access methods do a lot of chaining/buffering under the covers and so I'd be surprised if your large-LRECL datasets are actually hurting. Do consider striping, no matter the LRECL. -- David Andrews A. Duda and Sons, Inc.
