Programmes (1st day)

Hiroki Kataoka
Chairman, JPUG

Time

10:10 - 10:40 (30 minutes)

Abstract

It is my great pleasure to announce that the JPUG has recorded the tenth anniversary this year. It was really a turbulent decade for the IT world. The situation revolving around PostgreSQL has also been changed dramatically. At the time we established JPUG, a lot of SEs were not familiar with the word 'DBMS' as well as the word 'Open Source'. We started awareness campaign those days, step-by-step.

Time has changed, and PostgreSQL is one of the trusted selections to install RDBMS even in the mission critical and the enterprise environment. In this two days memorable conference, you will hear the history of our activities and its results, as well as the evolution of PostgreSQL all over the world including inside stories not well spoken yet.

I profoundly hope that everyone who considers installing RDBMS would feel familiarity with PostgreSQL as it has awfully been serious to every corner of this application.

Time

10:40 - 11:50 (70 minutes)

Abstract

Synchronous Replication (Synch Rep) is under development at NTT OSS Center, which will be integrated into PostgreSQL main body.

It is publicly proposed to PostgreSQL community so as to make it in time to 8.5 release. Synch Rep employes the log shipping function. WAL archive (transaction log of PostgreSQL) is transfered to the standby server, and the standby server uses it for recovery to implement replication. Replication and transaction completion are synchronously performed.

This characterizes the function to prevent data loss when the database server is accidentaly broken down.

 

This session covers these characteristics of Sync Rep, functions, archtecture, operation, and direction to the future. Demonstration is also provided.

Abstract

Discussion and demonstration of Hot Standby (HS) mode for PostgreSQL.

HS allows queries to be executed against a server during archive recovery. HS provides an important capability for replication, as well as additional control during a point-in-time-recovery of a damaged database. HS has twice been voted most anticipated new feature for PostgreSQL.

Abstract

NTT group is positively adopting open source software aiming at "Reduction of TCO".

NTT COMWARE has been focusing on the application of OSS to the telecom carrier systems for a decade, after the launch of linux center in 1999.

In this session, we would like to show our activity for the adoption of the OSS-DBMS, especially PostgreSQL,and also suggest the functions that seem to be necessary for being implemented when we apply PostgreSQL to larger systems from an SIer's point of view.

Abstract

SuperSQL, which has been developed in Toyama laboratory, is the database publishing extension of SQL. Its first edition was developed on QUEL of Ingres 8.9 in 1991, then the development has been moved on to PostgreSQL. SuperSQL produces tree structured output in various media such as HTML, PDF, SWF, XML, LDAP and so on.

SuperSQL is used at the end of introductory database lecture using PosgreSQL, by students to create Web view in individual database projects.

In this talk, we introduce SuperSQL's background, syntax and examples of basic usages. In addition, the advanced features such as dynamic presentation in Flash, X3D, Ajax, and Web application generation extension will be presented.

Abstract

In the context of the Arborea project, a leading group in tree genomics in Canada, we developed PostgreSQL databases to store information on the discovery of new genes and their potential link to wood quality traits.

One database, TreeSNPs, holds genomic (related to genes) data and the second, PhenoTree, is used to store phenotypic (observable traits) tree characterization data.

Formerly Access projects, the two databases were migrated to PostgreSQL on a Windows server and hold altogether approximately 4.5 Million records. They are being used by around 20 researchers from different institutions (universities, government research facilities), using a dedicated Rails web interface in one case, and PhpPgAdmin in the other. A brief demonstration of each database will be presented.

 

 

Profile

My field is forest genomics, and more specifically the study of the role of genes in wood formation and quality. As such, genomics projects generate everyday massive amounts of data in the form of gene sequences, sample identification and experimental results.

Hence, a part of my job consists of developing databases to store all these data and interact with other scientists to assess their needs for further development and data extraction.

My background is biology (B.Sc. U. of McGill) with further specialization in microbiology (M.Sc. U. of Montral), and my work has been mainly molecular biology and scientific databases for the past ten years.

Abstract

The reverse-geocoding service has been published.

If you request to it with the parameter latitude and lontitude which are points by a user or are got from GPS, it judges the placename of the place where the parameters point.

To construct it, PostGIS acts the important roles; The judgement function could be implemented by PostGIS builtin functions and spatial index, and PostGIS also processed the geospatial data used for judgement.

In addition, the development of it started on cheep knowledge on cargography and PostGIS. In this session, inside of it will be introduced with a little of knowledge on cartography, and how appriciable PostGIS is.

Abstract

Web applications users are growing steadily supported by the providers' fix rate for packet using. Smartpones in particular, the launche of Android and iPhone3GS gave a gread deal of leverage in expanding market share.

This session will cover the case example of WebDBSystem with PostgreSQL.

A training space, "Maitore" is designed to cultivate brain and maind during daily spare time. "Maitore" is something different from Twitter, SNS, or DS game "Noutore".

"Maitore" is the phrase training space for studens, businessmen and women, housekepers, and aged persons. Full-text search capability is achieved by the simple screen and operation. MySQL is generally popular for Ruby on Rails, but the speaker integrated Postgresql for the application, hoping to falimialize the world's most advanced Open Source database.

Abstract

Postgres database, relation, and index statistics are constantly updated by the statistics collector, providing useful data through Postgres system views and functions. Additional information is updated by the ANALYZE process. By collecting this data over time, database administrators can better quantify the behavior of their database installation. In OLTP environments that have loads which vary with time, this data can be particularly useful in noting correlations between overall system performance (such as CPU idle and IOWait) and specific database objects (e.g., heap hits, index utilization, and locks on particular relations).

The raw collected data can be unwieldy on its own given its volume and time-related nature. By taking advantage of a simple web framework and Javascript functionality, one can more easily view the data and quickly see relationships between the various database objects and system performance. A simple example of a data-collecting and viewing application will be presented along with explanations of the various statistics gathered by Postgres and how they can be used to identify database server performance issues.

Profile

Michael Glaesemann has been using Postgres since 2003, following the project closely and contributing when he can.

Michael is interested in relational theory in general and its implementation in Postgres. He provides explain-analyze.info, a public pasteboard for Postgres EXPLAIN output with highlighting of potential problem areas, as well as a neglected E.164 telephone number standard Postgres type on PgFoundry. He was hired as the first full-time DBA at myYearbook.com in November 2007 where he's cut his teeth on scaling Postgres, riding herd over an ever-increasing number of Postgres servers. Data visualization has been a key component of managing the installation.

Abstract

The OSS is much more common in a mission-critical enterprise system these days. However, a lot of commercial softwares are still taking role in the fields of database and applications servers. OSS is facing a barrier for 'one more push' to get over those situations.

Under those environment, however, SIOS thinks it important to propose the use of open source software in the fields of mission-critial applications to every customer, who could get aggressive IT management strategy with SIOS support.

In this session, a SIOS consultant in charge of the office systems will talk about the key on how mission-critical system is intentially incorporated the OSS under the such envirounment.
