On a UNIX operating system, if you have applied a support package stack that includes the kernel, or if you have applied a single support package to update the kernel, you have to execute the saproot.sh script to configure the ownership and permissions of some kernel files, including saposcol .
You have logged on to the operating system as a <SID>adm user.
