Friday, November 2nd, 2007

WAS does not seem to install any default init scripts, so I created one. You can configure it to start and stop multiple application servers by listing them all in the APPSERVERS variable (separated by spaces).

The Subsystem Device Driver [SDD] is a pseudo device driver designed to support the multipath configuration environments in the IBM TotalStorage Enterprise Storage Server, the IBM TotalStorage DS family, the IBM SystemStorage SAN Volume Controller.

How to get VMware Server working with an unsupported kernel and the vmware-any-any patch

Unfortunately, the vmmon and vmnet packages included in the VMware server distribution package don’t compile with the newest kernels. When I upgraded my laptop to Gutsy Gibbon a few weeks ago, I forgot to check if VMware server supports the new kernel. And, of course, it doesn’t yet. But luckily I found the vmware-any-any package, a patched version of the host kernel modules that works with newer kernel versions.

Updated version of the flash64.sh script for Ubuntu 7.10 Gutsy Gibbon
