  • Method for providing scaleable restart and backout of software upgrades for clustered computing
    Patent number: 6681389
    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.

  • 2-(O-Hydroxyphenyl)-pyrrole and process for its preparation
    Patent number: 4240964
    Abstract: 2-(o-Hydroxyphenyl)-pyrrole and a process for its preparation, wherein o-benzyloxybenzoic acid allylamide is reacted with phosgene in an inert solvent, the resulting imide-chloride is cyclized in the presence of a strong sterically hindered base and the benzyl protective group is then removed by hydrogenolysis.2-(o-Hydroxyphenyl)-pyrrole is a valuable intermediate for the synthesis of drugs. In particular, alkylamino-hydroxypropyl ethers thereof can, because of their .beta.-sympatholytic actions, be used for the treatment of coronary cardiac diseases, cardiac arrhythmias and hypertonia.
