A “Performance Evaluator” provides various techniques for tracking system events to diagnose root causes of application performance anomalies. In general, traces of system events involved in inter-thread interactions are collected at application runtime. These traces are then used to construct inter-thread dependency patterns termed “control patterns.” Control patterns are then evaluated to determine root causes of performance anomalies. Where an application terminates abnormally or full traces cannot be collected for some reason, partial control patterns are constructed for that application. In various embodiments, “fingerprints” are then generated from full or partial control patterns and are matched to fingerprints corresponding to operations in other control patterns extracted from reference traces collected on the same or similar systems. Matched fingerprints or control patterns are then used to deduce the root cause of application performance anomalies associated with full or partial traces.

An improved controlled release composition for non-parenteral administration of active agents and other therapeutics, particularly for oral or topical administration, has been developed. The composition is made by dispersing a complex formed of an active agent bound to an ion-exchange resin or to another form of resin or carrier, in a non-ionic non-aqueous (“NINA”) vehicle. The complexes are optionally coated with one or more layers of coating material to provide a controlled pattern of release of active agent from the carrier. Replacing the usual aqueous vehicle with a NINA vehicle, such as an oil or an ointment, allows the active agent-carrier complexes, with or without coatings, to be both orally and topically administered. The compositions can be formulated as powders, liquids, liquid suspensions, gels, capsules, soft gelatin capsules, tablets, chewable tablets, topical ointments, lotions, pourable or pumpable fluids, semisolid, crushable tablets, and unit-of-use sachets or capsules for reconstitution or direct application. The combination of multiple active agents is possible with this system, in which one or more active agents are bound to particles and one or more active agents are dissolved or dispersed in the NINA vehicle. This allows the combination of two or more active agents, which are otherwise incompatible, into a single dosage form.
