	The Cherenkov Telescope Array (CTA) will be the next generation ground-based observatory for gamma-ray astronomy at very-high energies. CTA will consist of two large arrays with 118 Cherenkov telescopes in total, deployed in Paranal (Chile) and Roque de Los Muchachos Observatories (Canary Islands, Spain). The Array Control and Data Acquisition (ACADA) system provides the means to execute observations and to handle the acquisition of scientific data in CTA. The Resource Manager & Central Control (RM&CC) sub-system is a core element in the ACADA system. It implements the execution of observation requests received from the scheduler sub-system and provides infrastructure services concerning the administration of various resources to all ACADA sub-systems. The RM&CC is also responsible of the dynamic allocation and management of concurrent operations of up to nine telescope sub-arrays, which are logical groupings of individual CTA telescopes performing coordinated scientific operations. This contribution presents a summary of the main RM&CC design features, and of the future plans for prototyping.

	When completed, the European Spallation Source (ESS) will have around half a million of installed cables to power and control both the machine and end-stations instruments. To keep track of all these cables throughout the different phases of ESS, an application called Cable Database was developed at the Integrated Control System (ICS) Division. It provides a web-based graphical interface where authorized users may perform CRUD operations in cables, as well as batch imports (through well-defined EXCEL files) to substantially shortened the time needed to deal with massive amounts of cables at once. Besides cables, the Cable Database manages cable types, connectors, manufacturers and routing points, thus fully handling the information that surrounds cables. Additionally, it provides a programmatic interface through RESTful services that other ICS applications (e.g. CCDB) may consume to successfully perform their domain specific businesses. The present paper introduces the Cable Database and describes its features, architecture and technology stack, data concepts and interfaces. Finally, it enumerates development directions that could be pursued to further improve this application.

WEPHA048	Management of IOCs at ESS	1204
	R.N. Fernandes, S.R. Gysin, T. Korhonen, J.A. Persson, S. Regnell ESS, Lund, Sweden M. Pavleski, S. Sah Cosylab, Ljubljana, Slovenia
	The European Spallation Source (ESS) is a neutron research facility based in Sweden that will be in operation in 2023. It is expected to have around 1500 IOCs controlling both the machine and end-station instruments. To manage the IOCs, an application called IOC Factory was developed at ESS. It provides a consistent and centralized approach on how IOCs are configured, generated, browsed and audited. The configuration allows users to select EPICS module versions of interest, and set EPICS environment variables and macros for IOCs. The generation automatically creates IOCs according to configurations. Browsing retrieves information on when, how and why IOCs were generated and by whom. Finally, auditing tracks changes of generated IOCs deployed locally. To achieve these functionalities, the IOC Factory relies on two other applications: the Controls Configuration Database (CCDB) and the ESS EPICS Environment (E3). The first stores information about IOCs, devices controlled by these, and required EPICS modules and snippets, while the second stores snippets needed to generate IOCs (st.cmd files). Combined, these applications enable ESS to successfully manage IOCs with minimum effort.
