Introduction to several common parameters of eclipse. ini

Document directory

• Modify JVM memory:-xmx
• Modify the permanent generation memory size

Later found that there is a better introduction of eclipse. ini article, it is recommended to go directly to see this article: http://developer.51cto.com/art/200906/126835.htm

 

 

Today, I encountered the JVM terminated exit code = 1 problem. Later, I modified eclipse. the reason is not clear at present, but for eclipse. the INI file is of interest, so I found some information about eclipse on the Internet. INI information.

1. -The VM Parameter options and parameter values are in different rows.
2. An absolute path of a Java executable file (such as java.exe)
3. -VM parameters must be placed before-vmargs. (My problem seems to be caused here)

Modify JVM memory:-xmx

JVM-related options should be placed under-vmargs. By modifying the-xmx parameter, you can adjust the JVM memory.

Modify the permanent generation memory size

The parameter is-XX: maxpermsize is related to what is permanent generation memory. On the Internet, I found a diagram about Java memory, which can be roughly understood, class Definition and interned strings ). This value is too small. Sometimes the outofmemoryerrors error occurs,
