Abstract: A method, computer program, and system are disclosed for validating query plans for an upgrade. Environment information corresponding to a target system is received. A query used on the target system is received. A target query plan generated by the target system is received. The query and the environmental information are imported into a test system. The test system corresponds to an upgrade of the target system. A test query plan is generated for the query using the test system. The target query plan is compared with the test query plan.

Abstract: A method, apparatus and program product for remotely administrating a computer server. An alert message is received from a remote server at a central support site. The alert message is matched to a contact person, i.e., systems administrator, for the server stored in a database at the central support site. A message is transmitted from the central support site to the systems administrator. When a call is received from the systems administrator at the central support site, the call is then matched to the alert message, and any further attempts to contact the systems administrator in response to the alert message is terminated at the central support site. The central support site waits for a call from the systems administrator for a predetermined period of time. If the time expires without a return call, a backup contact for the server is retrieved from the database at the central support site, and the message is re-transmitted from the central support site to the backup systems administrator.
