One such tool is a new Image Packaging System, a dependency-aware, network-aware package. According to Roberts, Image Packaging System virtually eliminates patching errors and increases the reliability of upgrades. The tool combines with ZFS, giving uses the ability to prepare a system for a live upgrade -- without the need to take down production services. It accomplishes this feat, Roberts writes, "by preparing an alternate boot environment so your upgrade process becomes only a restart."
The existing environment won't be overwritten, he notes, so if a problem occurs with the upgrade, rolling back to the previous version is a snap.
Further promoting uptime, Oracle says it is eliminating half of the restarts needed with Solaris 10; in addition, a new Fast Reboot technology brings servers back up in seconds instead of minutes. (That innovation could also be a boon for energy-conscious data center operators considering powering down servers when they're not in use.)
Solaris 11 is set for release at the end of the year.
