well, my prev answer was the heap only ;) sorry... about the ram size, we usually start with 800MB or 1 GB depending on the appl. the biggest have 2 GB memory we use two small VDISKs as swap ( 2*64MB ) and one or two dasd swap for 4MB up to 1 GB
if you need more memory, it might be better to start one more linux server ___________________________________________ Tore Agblad Volvo Information Technology Infrastructure Mainframe Design & Development, Linux servers Dept 4352 DA1S SE-405 08, Gothenburg Sweden Telephone: +46-31-3233569 E-mail: [email protected] http://www.volvo.com/volvoit/global/en-gb/ -----Original Message----- From: Linux on 390 Port [mailto:[email protected]] On Behalf Of Daniel Tate Sent: den 16 september 2010 00:25 To: [email protected] Subject: Good sources of information for WAS on Z sizing? In a day or so, I will be asking for sizing advice (practical, not redbook - redbooks and other theoretical sources have not been too beneficial to us - this mailing list on the other hand has).. but I would also like to know of any good resourcesdy (message boards, mailing lists, fidonet feeds, whatever) for websphere, especially websphere on Z.. We've given up on using LDAP SSO because of the memory consumption that nobody was able to find the source of (LDAP SSO turned on = uncontrolled memory growth until OOM_KILL even without apps loaded onto the appserver.. turn LDAP off, no problems).. Now we're onto sizing. We only have a dev environment with 7 servers, the LPAR has 15GB of storage, and we know we are going to need more. We will be looking for not only a number but verbose justification for that number (executives will demand that).. so we need as much ammo - theoretical and practical experience - as we can possibly gather. Our mainframe admin was expecting 15GB to be plenty, as we run our entire primary application (z/OS) on less memory than that - and he fully expected 1-2GB per system to be MORE than enough). I have asked our WAS admin for details of the final planned environment to pass along to as many people as I can to get real world advice. So does anyone have any good resources? This is WAS 6, SLES 11 GM, z/VM 5, on a z9. ---------------------------------------------------------------------- For LINUX-390 subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO LINUX-390 or visit http://www.marist.edu/htbin/wlvindex?LINUX-390 ---------------------------------------------------------------------- For more information on Linux on System z, visit http://wiki.linuxvm.org/ ---------------------------------------------------------------------- For LINUX-390 subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO LINUX-390 or visit http://www.marist.edu/htbin/wlvindex?LINUX-390 ---------------------------------------------------------------------- For more information on Linux on System z, visit http://wiki.linuxvm.org/
