Oracle JRE / JDK

1.8

Crucible requires the Java Runtime (JDK or JRE), version as noted. Pre-release/Early access versions of Java are not supported.

We highly recommend that you use the Oracle JVM (or OpenJDK for Linux only). Other Java implementations have not been tested.

You can download an Oracle Java Runtime.

For the OpenJDK, download and install instructions for Linux flavors are at http://openjdk.java.net/install/.

Please note:

• Once you have installed the Java, you need to set the JAVA_HOME environment variable. See Installing Crucible on Windows or Installing Crucible on Linux and Mac for details.
• If you are using a 64-bit JVM, please ensure that you've set your max heap size (--Xmx) to a reasonable value, considering the RAM requirements of your system.

1.8 (Linux only)

Microsoft Windows

Linux

Apple Mac OS X

HSQLDB

Bundled; for evaluation use only

The Crucible built-in database, running HSQLDB, is somewhat susceptible to data loss during system crashes. We recommend that you do not use HSQLDB for production systems.

External databases are generally more resistant to data loss during a system crash and are more suited for production use.

See the  Crucible Database documentation  for further details.

CPU

1.8GHz or higher, a single core is sufficient. More cores or higher GHz will result in better load-handling ability.

RAM

1GB minimum, 2GB will provide performance "headroom". Your Java heap should be sized at 512MB.

I/O

Crucible's input/output is an important element of its overall performance. If Crucible accesses your repository remotely, make sure that the throughput is maximum and the latency minimum (ideally the servers are located in the same LAN, running at 100Mbps or faster).
