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?

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?

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?
