Security violations when the RESOLVER process starts

Technote (troubleshooting)


Problem(Abstract)

Whenever the RESOLVER address space is started during UNIX System Services initialization, it gets a security violation. However, processing continues with no other adverse effects.

Symptom

If RACF is the security product, the following message is issued:

   ICH408I USER(xxxxxxxx ) GROUP(gggggggg) NAME(aaaaaaaaaaaaaaaaaaaa)
   /path/name CL(DIRSRCH ) FID(nnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnn)
   INSUFFICIENT AUTHORITY TO CHDIR
   INTENT(--X)  ACCESS ALLOWED(OTHER      ---)
   EFFECTIVE UID(uuuuuuuuuu)  EFFECTIVE GID(gggggggggg)


Cause

The path specified as the HOME directory in the OMVS segment associated with the RESOLVER address space (via the STARTED class profile) is either invalid or has not yet been mounted when the RESOLVER is started during OMVS initialization.

Resolving the problem

Change the user profile to specify the root directory as HOME. The specification is there only to allow the UNIX process to be created; it is not actually used for any file accesses performed by the RESOLVER address space.
