JIRA の要件

Please read the Supported Platforms page for JIRA. The JIRA Supported Platforms page contains important information on the client/server software supported for JIRA 4.1.x, including:

• ブラウザ
• Operating systems
• Java (JRE/JDKs)
• Application servers (if you are installing JIRA WAR-EAR)
• データベース

Please also read the information below regarding client/server software for JIRA.

1. ブラウザ

If you have disabled Javascript in your browser or are using a script blocker like NoScript, you will need to enable Javascript for JIRA to get the full experience JIRA has to offer.

2. Java

JIRA requires a Java Developers Kit (JDK) to be installed on the server (see Supported Platforms for supported JDK versions). For instructions on how to do this, please refer to Installing Java.
Currently Sun's JDK is available for Windows (32 bit + 64 bit), Solaris (SPARC + 32 bit + 64 bit) and Linux Platforms (32 bit + 64 bit). If you are a Mac OSX user, Apple also provides a specific JDK that has been optimised for its hardware and OS.

3. アプリケーションサーバー

JIRA is a web application, so requires an application server.

• JIRA Standalone ships pre-configured with the Apache Tomcat application server, which is a stable, light weight and fast performing server.
• JIRA WAR/EAR can be installed into any of the supported application servers (see Supported Platforms) provided they are compatible with your chosen operating system and JDK. Note that manual configuration will be required.

4. データベース

JIRA requires a relational database for storage of issue data. JIRA supports most relational database servers, so we suggest using the one that you are most comfortable administering.

• JIRA Standalone ships pre-configured with the HSQLDB database, which is suitable for evaluation purposes. HSQLDB is prone to database corruption. Before deploying to a production environment, we strongly recommend that you connect JIRA Standalone to an enterprise database (see Supported Platforms for the list of supported databases).
• JIRA WAR/EAR can be connected to any of the supported databases (see Supported Platforms), provided they are compatible with your application server.

During evaluation, JIRA will run well on any reasonably fast workstation computer (e.g. 1.5+ Ghz processor). Memory requirements depend on how many projects and issues you will store, but 256MB ( of Java heap size ) is enough for most evaluation purposes. (Note: most people start by installing JIRA Standalone on their local computer. It is easy to move JIRA to a production server later).

The hardware required to run JIRA in production depends mainly on the number of issues and users that your installation will have, as well as the maximum number of concurrent requests that the system will experience during peak hours.

• If you are planning to have a small number of projects (10-20) with 1,000 to 5,000 issues in total and about 100-200 users, a recent server (2.0+GHz Quad Core CPU) with 1-2GB of available RAM should cater for your needs.
• If you are planning for a greater number of issues and users, adding more memory will help. We have reports that allocating 1GB of RAM to JIRA is sufficient for 100,000 issues. If in doubt, allocate more memory than you think you need.
• If your system will experience a large number of concurrent requests, running JIRA on a multi-CPU machine will increase the concurrency of processing the requests, and therefore speed up the response time.

For reference, jira.atlassian.com has over 70,000 issues and over 30,000 user accounts. The system runs on a 64bit Quad processor. The server has 32 GB of memory with 1.5 GB allocated to JIRA.

Please note that performance heavily depends on your usage pattern. As a general rule, if you wish to store more than 200,000 issues in JIRA we recommend that you set up separate instances of JIRA on different physical machines and split your projects and issues between the instances. You can follow the instructions on splitting a JIRA instance, if you need to convert an existing JIRA instance into multiple instances.

We would appreciate it if you let us know what hardware configuration works for you. Please create a ticket in our support system with your hardware specification and mention the number of users and issues in your JIRA installation.

Install JIRA Standalone (recommended); or Install JIRA WAR/EAR.
