The IBM fix introduced a new facility class STGADMIN.IGG.CATALOG.SECURIY.BOTH. Users having READ authority to STGADMIN.IGG.CATALOG.SECURIY.BOTH are required to have ALTER authority to both the CLUSTER and the PATH or AIX when defining a path or AIX. This ensures sufficient authority to both the CLUSTER and AIX or PATH on subsequent VSAM OPENs. Problem is resolved when PTFs are applied and READ authority is established to STGADMIN.IGG.CATALOG.SECURIY.BOTH for all users.

IGG.CATALOG.SECURIY.BOTH UID(-) SERVICE(READ) ALLOW
