Verifying the user OMVS segment

If a user or daemon is not properly defined with an OMVS segment, you need to verify that the user or daemon has an OMVS segment with a UID.

Example: To verify that the DAEMONU daemon was properly defined with an OMVS segment, issue:
LU DAEMONU OMVS
Result: You will see output similar to the following:
LU DAEMONU OMVS

  USER=DAEMONU  NAME=UNKNOWN  OWNER=WELLIE    CREATED=92.104
   DEFAULT-GROUP=DAEMONG   PASSDATE=92.125  PASS-INTERVAL=N/A
   ATTRIBUTES=SPECIAL OPERATIONS
   ...
 GROUP=DAEMONG  AUTH=USE CONNECT-OWNER=WELLIE CONNECT-DATE=92.104
      CONNECTS=    82  UACC=NONE     LAST-CONNECT=95.261/14:09:38
  ...
  OMVS INFORMATION
  ----------------
  UID= 0000000000
  HOME= /
  PROGRAM= /bin/sh
  CPUTIMEMAX=NONE
  ASSIZEMAX=NONE
  PROCUSERMAX=NONE
  THREADSMAX=NONE
  MMAPAREAMAX=NONE

You should now see that the UID is 0. (The UID for all daemons must be 0, which gives superuser authority to the daemon.)
