Embodiments relate to a system, program product, and method for protecting cache access in a multi-tenant environment, and, more specifically, for allowing access to specified data, encrypted or unencrypted, in a shared cache to authorized tenants, while denying access to the data for unauthorized tenants. The system includes a server including one or more shared cache and a plurality of tenant devices coupled to the server. The server is configured to run one or more applications thereon, where each tenant has access to one or more authorized instances of the applications. The system also includes a cache proxy coupled to the tenant devices and the shared cache. The cache proxy facilitates enforcing one or more schemes to provide for separation of data for authorized tenants and their users using the shared cache from unauthorized tenants and users.

Protecting cache accesses in multi-tenant processing environments

A method for analyzing and resolving problems in a process server is disclosed herein. In one embodiment, such a method may include receiving a log file associated with an application running on the process server. The application may be made up of higher-level service component artifacts, and lower-level implementation artifacts used to implement the higher-level service component artifacts. The method may further include identifying error messages in the log file and determining which implementation artifacts are associated with the error messages. The method may further include mapping the implementation artifacts to service component artifacts associated with the implementation artifacts. The error messages may then be displayed along with their relationship to the service component artifacts. A corresponding apparatus and computer program product are also disclosed and claimed herein.
