Eclipse startup is controlled by eclipse.ini file which comes by default installation under ECLIPSE_HOME/eclipse.ini.

Uses of this eclipse.ini file.

• In case if your workspace is failing during startup of Eclipse then try to increase MaxPermSize file from 256m to higher for example 512m or 1024m

• If there is any certain crash of JVM and you will see some hs_err_pid file for that try to increase Heap size -Xmx512m to -Xmx1024m

• If you upgrade your JDK or JAVA_HOME and want to use current JVM home in eclipse then try to use -vm option.
