hi,

I have redhat 8.3, after installation Cache and everything looks good , when i stop the DB by /usr/cachesys/cstop i get :

I think it belongs to permissions ' what permission exactly I need?

Hello Abed,

What permissions do you have exactly for cstop, the database directories / cache.lck, and the contents of the bin directory?

Perhaps the Unix permissions docs would be helpful:

UNIX® Users, Groups and Permissions

Also, can you try using "ccontrol stop" rather than calling cstop directly?

During installation you specified the user who owns the system. Try running cstop as that user.

I did that by root user, and still get the same .

When i start the db the cache.lck created by root:cacheusr , that mean if the owner created the lck why he cant remove it?
