MemoryAnalyzer/Shared Installation
Sometimes it can be useful to install Eclipse Memory Analyzer in a shared directory so that many people can use it, but ideally with their own settings.
See [Eclipse multi-user installs](https://help.eclipse.org/latest/index.jsp?topic=%2Forg.eclipse.platform.doc.isv%2Freference%2Fmisc%2Fruntime-options.html)
1. Unpack Eclipse Memory Analyzer into a location which can be shared
2. Option: Start MAT and set up preferences etc. as required which will be the default configuration
3. Add the following to MemoryAnalyzer.ini. This stops a root user from running Memory Analyzer and overwriting key files in the shared directories.
-protect root
4. Add to configuration/config.ini a line such as
osgi.instance.area=@user.home/MemoryAnalyzer
This sets the workspace as the default would be under the Memory Analyzer install directory, so would not be writable. This means the user does not have to specify -data
5. Make all the Memory Analyzer files and directories publicly readable, but not writable.
6. The error logs will go to a location like ~/.eclipse/org.eclipse.mat_1.13.0_87691952_linux_gtk_x86_64/configuration/1651585377771.log
The org.eclipse.mat and 1.13.0 come from .eclipseproduct, linux from the os, gtk from ws, x86_64 from arch.
