Overview

GridDB is Database for IoT with both NoSQL interface and SQL Interface.

Please refer to GridDB Features Reference for functionality.

This repository includes server and Java client. And jdbc repository includes JDBC Driver.

Quick start (Using source code)

We have confirmed the operation on CentOS 7.6 (gcc 4.8.5).

Note: Please install tcl like "yum install tcl.x86_64" in advance.

Build a server and client(Java)

$ ./bootstrap.sh
$ ./configure
$ make 

Note: When you use maven build for Java client, please run the following command. Then gridstore-X.X.X.jar file is created on target/.

$ cd java_client
$ ./make_source_for_mvn.sh
$ mvn clean
$ mvn install

Start a server

$ export GS_HOME=$PWD
$ export GS_LOG=$PWD/log
$ export PATH=${PATH}:$GS_HOME/bin

$ bin/gs_passwd admin
  #input your_password
$ vi conf/gs_cluster.json
  #    "clusterName":"your_clustername" #<-- input your_clustername

$ bin/gs_startnode
$ bin/gs_joincluster -c your_clustername -u admin/your_password

Execute a sample program

$ export CLASSPATH=${CLASSPATH}:$GS_HOME/bin/gridstore.jar
$ mkdir gsSample
$ cp $GS_HOME/docs/sample/program/Sample1.java gsSample/.
$ javac gsSample/Sample1.java
$ java gsSample/Sample1 239.0.0.1 31999 your_clustername admin your_password
  --> Person:  name=name02 status=false count=2 lob=[65, 66, 67, 68, 69, 70, 71, 72, 73, 74]

Stop a server

$ bin/gs_stopcluster -u admin/your_password
$ bin/gs_stopnode -u admin/your_password

Quick start (Using RPM)

We have confirmed the operation on CentOS 7.6.

Note:

• When you install this package, a gsadm OS user are created in the OS.
  Execute the operating command as the gsadm user.
• You don't need to set environment vatiable GS_HOME and GS_LOG.
• There is Java client library (gridstore.jar) on /usr/share/java and a sample on /usr/gridb-XXX/docs/sample/programs.

Install

(CentOS)
$ sudo rpm -ivh griddb-X.X.X-linux.x86_64.rpm

Note: X.X.X is the GridDB version.

Start a server

[gsadm]$ gs_passwd admin
  #input your_password
[gsadm]$ vi conf/gs_cluster.json
  #    "clusterName":"your_clustername" #<-- input your_clustername
[gsadm]$ gs_startnode
[gsadm]$ gs_joincluster -c your_clustername -u admin/your_password

Execute a sample program

$ export CLASSPATH=${CLASSPATH}:/usr/share/java/gridstore.jar
$ mkdir gsSample
$ cp /usr/griddb-X.X.X/docs/sample/program/Sample1.java gsSample/.
$ javac gsSample/Sample1.java
$ java gsSample/Sample1 239.0.0.1 31999 your_clustername admin your_password
  --> Person:  name=name02 status=false count=2 lob=[65, 66, 67, 68, 69, 70, 71, 72, 73, 74]

Stop a server

[gsadm]$ gs_stopcluster -u admin/your_password
[gsadm]$ gs_stopnode -u admin/your_password
