chatr explanation

[Alfonso_15]

Hi.
I have a trouble with a shared library in development machine. I compare this file with the one in production machine using comand chatr and the only one difference found is that in development machine show this additional attribute :
"explicit unloading enabled"

Could you guys give me a explanation what that means and how I can set it enabled or disabled? Thanks in advance.

I'm not sure if the shared library was written in C++ or Java which files you are getting this information from but the meaning...


From within the single "application manager" application, we start and stop other applications and allow explicit unloading of classes. All applications that are executing within this environment share all loaded classes entirely, i.e. all code and data is loaded only once and then reused (shared).


Again, might be helpful if you gave the files that you compared to derive this information.

From ld(1)

---
-B bind

...

nodelete

Mark the shared library so that an explicit unload using dlclose() or shl_load() returns success silently without detaching the shared library from the process.

You can change it with chatr -B [nodelete|delete]

$ chatr -B nodelete
