J-PARC (Japan Proton Accelerator Research Complex) consists of much equipment. In Linac and 3 GeV rapid cycling synchrotron ring (RCS), the data of over the 64,000 EPICS records for these equipment has been collected. The Data volume will be about 10 TB in 2020. The data have been being stored by a Relational Data Base (RDB) system using PostgreSQL, but it is not enough in availability, performance, and capability to increase of data volume flexibility. Hadoop/HBase, which is known as a distributed, scalable and big data store, has been proposed for our next-generation archive system to solve these problems. The archiving system was built and verified about data transition or database utilization. This report shows the result of the modification of the archive system.

The Linac and the RCS in J-PARC provide enormous operation data and we have been stored them into PostgreSQL. We are planning to replace it with HBase, a data store specialized for big-data and is on a distributed file system provided by Hadoop, using a cluster with advantages including automatically recovering and easily extending the capacity. In the previous presentation we reported we updated HBase/Hadoop in our test system and we showed issues to fix our tools in the new system, while we also mentioned issues about the construction of our cluster itself. In this presentation we are reporting we have re-designed and re-constructed the cluster with resolving the issues, including enhancing hardware of master nodes, creating automatic scripts to construct nodes, and introducing monitoring tools for nodes. Having accordingly adjusted the configurations of HBase/Hadoop and measured the performance of our new system, we are also reporting its results and considerations.

J-PARC (Japan Proton Accelerator Research Complex) consists of much equipment. In Linac and 3 GeV rapid cycling synchrotron ring (RCS), the data of over the 64,000 EPICS records for these equipment has been collected. The Data volume is about 2 TB in every year, and the stored total data volume is about 10 TB. The data have been being stored by a Relational Data Base (RDB) system using PostgreSQL, but it is not enough in availability, performance, and capability to increase of data volume flexibility. Hadoop/HBase, which is known as a distributed, scalable and big data store, has been proposed for our next-generation archive system to solve these problems. The test system was built and verified about data transition or database utilization. This report shows the current status of the new archive system, and its advantages and problems which have been obtained through our verification.

J-PARC is consists of much equipment. In Linac and 3GeV synchrotron, the data of over the 64,000 EPICS records for these apparatus control is being collected. The data has been being stored by a RDB system using PostgreSQL now, but it is not enough in availability, performance, and extendibility. Therefore, the new system architecture is required, which is rich in the pliability and can respond to the data increasing continuously for years to come. In order to cope with this problem, we considered adoption of the distributed database architecture and constructed the demonstration system using HBase. We present results of these demonstration.

The installation of Cs-seeded RF-driven H
ion source (RF ion source) to J-PARC LINAC is scheduled in 2014. Similarly the replacement of RFQ III from RFQ is scheduled in 2014. The test stand of the cooperation of RF ion source & RFQ III is being made in the J-PARC LINAC building for the beam acceleration examination now. The J-PARC control group designed test stand control system by thinking that test stand control system had to be equal to J-PARC accelerator control system. Specifically, Introduction of MPS for protect an apparatus. Implementation of EPICS environment for remotely controlling the equipment. It is construction of the timing system for sending a timing signal to each accelerator component device. This report describes construction of the control system in a test stand.

J-PARC is consists of much equipment. In Linac and 3 GeV synchrotron, the data of over the 64,000 EPICS records about these apparatus control has been collected. The data has been being stored by a RDBMS (Rerational Data Base Management System) using Postgre SQL now, but it is not enough in availability, performance, and extendibility. Therefore, we think that the new system architecture excellent in the pliability will be required, which is rich in the pliability and can respond to the data which continues increasing for years to come. In order to deal with this problem, we considered use of distributed database system and constructed the demonstration system using HBase. We present results of these demonstration.
