For SDA, the certificate trust store is Tomcat based and located in the JRE \LIB\SECURITY folder which by default is in the following location for Serena Common Tomcat: C:\Program Files\Serena\common\jre\8.0\lib\security
The SDA client does not require any Java or JRE in the browser. This applies to SDA versions 5.x and 6. SDA Servers, Agent Relays and Agents will require a JRE -- please refer to the documentation for the SDA version in question to determine acceptable version numbers for these components.
"Download and install the JDK – not a JRE – that corresponds to your operating system" However it also says on page 43: "All server and agent relay machines require Java JRE 6 or greater."
Unexpected Problems Installing when you do not have full permissions on folder where install kit is located /tmp file system is configured noexec Error: Bundled JRE is not binary compatible with OS/Architecture
When an agent is upgraded using the GUI, the Agent's war file is upgraded, but the JRE used by the agent is not upgraded. If an agent has been deployed for some time and perhaps even upgraded a time or two, the JRE may be rather old. Sometimes it is desirable to update the bundled JRE, sometimes there are other reasons to upgrade an agent, such as a corrupt installation folder.
The DA Agent 6.3.3 occupies less than 100MB of disk space on an agent when the installation is finished. However, when it is installed with its own JRE , the addition of the JRE takes the installation up to approximately 270+ MB.
