Verifying SERNET User ID Privileges

If you are already using TCP/IP for communications with ChangeMan ZMF, SERNET will already have a user ID with an OMVS segment assigned. For example, you may use SERNET to communicate with ChangeMan ZDD or use the ChangeMan ZMF Load Balancing Option (LBO). However, user privileges and/or a Unix home directory may not be established.

To verify privileges for an existing SERNET user ID:

  1. Find the current SERNET user ID.

    1. Use SDSF to examine a running ChangeMan ZMF task or the JESMSGLG of the job output from a previous execution of ChangeMan ZMF.

    2. At the top of the message log, usually next to the message

    $HASP373 STARTED

    find message IEF695I. This message includes an ASSIGNED message line that identifies the SERNET user ID.

  2. Retrieve the OMVS segment for the SERNET user ID.

    1. At the TSO command line, issue the following command:

      LU userid OMVS

      where userid is the SERNET user ID found above, such as sernet.

    2. If no OMVS segment is returned, ask your systems programmer or security administrator to add one. (See "SERNET User ID" for required privileges.)

    3. If an OMVS segment exists for the user ID, verify that the UID is set to zero and note the Unix home directory (for example, /u/sernet). If either are missing, ask your security administrator to add it to the OMVS segment.

 

 

PRIVILEGES  

  • UID(0) is not required for the HTTP server.

  • UID(0) is recommended but not required for the SERNET server. The SERNET server already runs as APF-authorized. The server must have read, execute, and write privileges to the HFS file system, and in particular, anything that starts with the home directory of the server's user ID.
