We have a couple of sandbox sysplexes (2 LPARs per sysplex) that have "static lpars". But I have to share a couple of other monoplex sandbox environments in a single LPAR. One of them is able to share the LOADxx member with the other sandboxes (the one up and running most often). The other one is just IPLed with a different LOADxx member when we need that system active. -- Mark Zelden - Zelden Consulting Services - z/OS, OS/390 and MVS mailto:m...@mzelden.com Mark's MVS Utilities: http://www.mzelden.com/mvsutil.html Systems Programming expert at http://expertanswercenter.techtarget.com/ ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN
