Deployment notes

  • A schema change is required for bug #62901. Such a change is classified as transparent because the software can be effectively upgraded after the db is upgraded and without stopping the service. However, under high load the schema change may fail as it requires an exclusive table lock, which may not be granted by Oracle. In such a case, the service needs to be stopped for a short while; see the release notes for more details on the upgrade procedure.
  • Due to the implemented changes in the Makefile infrastructure, the SRM RPMs have been better rationalized and a new RPM is provided, which contains the gSOAP libraries used by the other components. All other RPMs except for the admin one depend on it.
