Problem summary

  • ****************************************************************
    * USERS AFFECTED: Users performing a keylabel rotation on a    *
    *                 VSAM sphere that has an Alternate Index.     *
    ****************************************************************
    * PROBLEM DESCRIPTION: S0C1 in GZDACT3 at +5FF2.  This occurs  *
    *                      during a keylabel rotation that         *
    *                      includes an AIX.                        *
    ****************************************************************
    * RECOMMENDATION: Apply the provided PTF.                      *
    ****************************************************************
    During keylabel rotation, the keylabel for the Alternate Index
    (AIX) is not located, causing zDMF to attempt to perform a
    Decrypt.  This causes the S0C1 when no encryption information
    is found for the AIX.
    

Problem conclusion

  • The keylabel for the Alternate Index (AIX) will be obtained
    from the base cluster control block area.
