This page describes the supported platforms and hardware requirements for Crowd 3.3.

Key(tick) = Supported. (error) = Not Supported (warning) = Deprecated


Java version

Notes
Oracle JDK (1) (tick) 1.8
  • JDK versions earlier than 8u65 might have problems connecting to LDAP servers over SSL. For more details, see CWD-4444 - Secure LDAP connections are broken when using Java 1.8u51, 1.8u60, 1.7.0_85+ and 1.6.0_101+ RESOLVED

  • JDK 1.8u151 might have problems with gzip compression of static resources. For more details, see CWD-5001.
OpenJDK (tick) 1.8
  • Our Support and Engineering teams use AdoptOpenJDK to replicate any issues raised with OpenJDK. If you’re using a different distribution of OpenJDK (e.g. Zulu), we’ll still provide support for our products. However, if the bug is caused by a problem in Java distribution, we’ll ask you to reach out to the Java distributor for help.

Notes:

 1. JDK:

  • It is not enough to have the JRE only. Please ensure that you have the full JDK. You can download the Java SE Development Kit (JDK) from the Oracle website.
  • Once the JDK is installed, you will need to set the JAVA_HOME environment variable, pointing to the root directory of the JDK. Some JDK installers set this automatically (check by typing 'echo %JAVA_HOME%' in a DOS prompt, or 'echo $JAVA_HOME' in a shell). If it is not set, please see Setting JAVA_HOME.

 2. Operating systems: Crowd is a pure Java application and should run on any platform provided the Java runtime platform requirements are satisfied.

 3. MySQL: Please ensure that you set transaction isolation to 'read-committed' instead of the default 'repeatable-read', as described in the database configuration guide.

 4. HSQLDB: Crowd ships with a built-in HSQL database, which is fine for evaluation purposes but is somewhat susceptible to data loss during system crashes. For production environments we recommend that you configure Crowd to use an external database.

Hardware Requirements

The hardware required to run Crowd depends significantly on the number of applications and users that your installation will have, as well as the maximum number of concurrent requests that the system will experience during peak hours.

During evaluation Crowd will run well on any reasonably fast workstation computer (eg. 1.5+Ghz processor). Memory requirements depend on how many applications and users you will store, but 256MB is enough for most evaluation purposes.

Most users start by downloading Crowd, and running it on their local computer. It is easy to migrate Crowd to your enterprise infrastructure later.

We would appreciate if you let us know what hardware configuration works for you. Please create a support request in Jira with your hardware specification and mention the number of applications and users in your Crowd installation.

While some of our customers run Crowd on SPARC-based hardware, Atlassian only officially supports Crowd running on x86 hardware and 64-bit derivatives of x86 hardware.
