The Serena Release Automation server must use the 32-bit JDK for the Windows 2003 64-bit server; the 64-bit JDK can be used for agents. Because Serena Release Automation does not require a multi-gigabyte heap, there is little advantage to using a 64-bit JVM. For 64-bit Windows installations, Serena Release Automation uses a 32-bit JVM; for other 64-bit platforms, Serena Release Automation uses a 64-bit JVM, as the following table illustrates:
Table 7. JVM Support
| Operating System | Operating System | JVM 64-bit |
|---|---|---|
| Windows 32-bit | yes | NA |
| Windows 64-bit | yes | yes |
| Non-Windows 32-bit | yes | NA |
| Non-Windows 64-bit | yes | yes |
