Are you suggesting that before DB2 references a page containing a buffer, it checks to see if it is paged out? And that if it is paged out, it doesn't use the record in the buffer, but instead reads it into a different page? That makes no sense to me. -- Tom Marchant ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
