I'm finally in the process of firing up some "boxes" under VM to replace some aging AIX critters and I could use some advise as to real memory and swap allocations for these new guys.
1st victim was a DB2 connect enterprise unlimited server - cut it to production 2 weeks ago and everything is good. 246900k of memory and 3G of swap, so far, so good except for a small issue with java versioning v1.5 on new box, v1.3 on oldest client app - but that is a java issue that would show up on any platform with the new version. 2nd victim is a DB2 ESE and WebSphere MQ server - can't even fire up the tools database because the bufferpools don't have enough memory. This is where the advise is needed since the IBM docs don't have a recommended starting point for the z/VM environment ( DB2 9.5 fixpack 3b) and I really don't want to scarf all of the vm resources for this machine when the grand plan ( insert evil laugh here ) is to put as many AIX and intel linux onto this platform (Z) as we can and still maintain decent performance. Current AIX box is a 2-way power3 box with 16G of memory - low utilization in a development environment. 3rd victim is a WebSphere AppServer box - 6-way power4 box with 16G memory. Low to moderate utilization in a development environment with a second instance of WAS for background production use ( the moderate utilization part - when it is active ). Current VM lpar has 2 IFL, 9G cstor, 3G estor, z/VM 5.3 and SuSE 10.2 guests Thanks, Bruce ---------------------------------------------------------------------- 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
