JIRA Database Requirements

Connecting JIRA applications to SQL Server 2012 - Atlassian
Java If you intend to use the Windows Installer or Linux Installer to install JIRA, there is no need to install and configure a separate JDK/JRE since these executable files will install and configure their own JRE to run JIRA, otherwise you will have to install a supported version of the ORACLE Java runtime. Consult the supported versions here.
  • For a small number of projects (less or equal to 100) with 1, 000 to 5, 000 issues in total and about 100-200 users, a recent server (multicore CPU) with 2GB of available RAM and a reasonably fast hard drive (7200 rpm or faster) should cater for your needs.
  • For more than 100 projects you should monitor JIRA memory usage and allocate more memory if required.
  • If your system will experience a large number of concurrent requests, running JIRA applications on a multicore CPU machine will increase the concurrency of processing the requests, and therefore, speed up the response time for your users.
  • For reference, we have a server that has a 2 Intel(R) Xeon(R) CPU E5520 @ 2.27GHz (16 logical cores) with 32GB of RAM. This server runs Apache, various monitoring systems, and two JIRA application instances:
Database Using the embedded H2 database is not supported in production. You must install and connect your JIRA instance to an enterprise database supported by Atlassian.
Security Symantec must be uninstalled from the server that you want to install JIRA applications on, as it is known to dramatically reduce application performance. For more information, see this knowledge base article: Crashes and Performance Issues Troubleshooting.
