You'll get more than that! We had a large IMS/DB2 environment that went from 10GB (2C/8E) to 2GB (ignored the XSTOR). Paging went through the roof; the AUX couldn't handle it; transactions died; eventually the sub-systems crashed. So, yes, you DO need to de/re-activate and change the definition in a large online environment! - Too busy driving to stop for gas! ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
