Oracle Parallel Server (OPS) is a shared disk RDBMS. We present a high level overview of the main architectural issues of OPS and their evolution throughout the releases of the Oracle database. The Oracle relational database can be used either in exclusive or shared mode. In exclusive (the most traditional) mode only one Oracle instance can mount or open the database. The Oracle Parallel Server...

Context: One of the important issues of software testing is to provide an automated test oracle. Test oracles are reliable sources of how the software under test must operate. In particular, they are used to evaluate the actual results that produced by the software. However, in order to generate an automated test oracle, oracle challenges need to be addressed. These challenges are output-domain...

Quantum computation requires large classical datasets to be embedded into quantum states in order exploit parallelism. However, this embedding considerable resources. It would therefore desirable avoid it, if possible, for noisy intermediate-scale (NISQ) implementation. Accordingly, we consider a classical-quantum hybrid architecture, which allows input data, with relatively small-scale system....
