Abstract
Platform and/or application software on all online, machine/servers in a cluster is updated without manually taking each machine/server offline. Initially, platform and/or application software for updating is stored in respective directories in an APPLY phase. Next, the new platform and/or application software is activated with or without a trial/test phase in an ACTIVATE phase. Where the new platform and/or application software is activated with a trial/test phase, a ROLLBACK phase is either automatically or manually invoked by the application in the event of a failure of the new software for backing out the new platform and/or application software and reactivating the previous platform and/or application software. An OFFICLAL phase then transitions the new platform and/or application software to the official state followed by a REACTIVATE phase for reactivating the backup copy of the previous/old platform and/or application software after the new software has been made official.
