Upgrading the server without stopping ServiceOptimizer

 For Bugfix releases only, it is possible to do a staged upgrade of the software on the slave installations of a ServiceOptimizer instance, provided that some or all of the slaves run on different SPHOMEs.  This means that during the upgrade some SPHOME locations within a ServiceOptimizer instance will have been upgraded while others have not.

 However, once you come to upgrade the SPHOME on which the master installation for the instance is running, the whole ServiceOptimizer instance (the master and all slave installations) must be stopped and all system monitors closed down.  This is so reagardless of whether the SPHOME for the master installation also runs some slaves or whether the master SPHOME is dedicated to the master installation.

titleInstructions for Upgrading server slave installations without stopping ServiceOptimizer

To do this:

  1. Identify those host(s) that are running components from the SPHOME location to be upgraded and verify that none of these are running the master installation (see above)
  2. Stop ServiceOptimizer on these host(s) (by stopping the service or running the stop script).  This will stop slave system monitor and the components that are running on the host(s).
  3. Upgrade the software at the SPHOME location.
  4. Start ServiceOptimizer on these host(s) (by starting the service or running the startup script).
