Follow the install guide of the Eclipse Titan ( see https://www.eclipse.org/downloads/download.php?file=/titan/Eclipse_installationguide.pdf ), especially chapter 5.2:
5.2. Configuring Java
You might need to modify your eclipse.ini file (usually located in the same directory as your eclipse executable.)
It is suggested to have at least 1GB and recommended 2 GB free memory per 1 million TTCN-3/ASN.1 source code lines (but it strongly depends on the code complexity). In Java it is controlled via the Xmx option.
For example, if Java 1.6 or 1.7 is applied and a project of 2 million TTCN-3 code lines is edited, the suggested settings in eclipse.ini are these:
-vmargs
-XX:MaxPermSize=2048M
-Dosgi.requiredJavaVersion=1.7
-Xms1024M
-Xmx4g
If Java 1.8 is used then MaxPermSize is ignored, its support is removed. Use these settings instead:
-vmargs
-Dosgi.requiredJavaVersion=1.8
-XX:+UseG1GC
-Xms1024M
-Xmx4g
NOTE: If you cannot edit the eclipse.ini file, you can start eclipse with flags. For example
modifies the maximum memory allocation for the virtual machine.
Hopefully this helps.
Best regards
Jeno
