    This IBM Redbooks publication describes the new functions of z/OS Version 1 Release 7. These functions further strengthen the zSeries platform with enhancements designed to deliver increased availability of z/OS UNIX System Services (z/OS UNIX), to support new security standards, and to improve enterprise-wide workload management. Enhancements are made to the following areas:

    Application integration with enhancements to the zSeries File System (zFS)

    Enhanced security with Communications Server support for IP filtering, Internet Key Exchange (IKE), and Virtual Private network (VPN), without requiring the use of the Integrated Security Services Firewall Technologies

    Security Server (RACF) support for mixed-case passwords

    Improved availability with TCP/IP sysplex autonomics

    Greater scalability with support for sequential data sets larger than 65,535 tracks

    System Logger and XRC+ optimization of duplexing log data

    Greater ease of use with the IBM Health Checker for z/OS

    z/OS UNIX dynamic service activation and a new dynamic service activation function

    JES2 has checkpoint problem recovery and supports TCP/IP for NJE networking

    A new direct access device space management/Common VTOC Access Facility (DADSM/CVAF) device support address space starts during a system IPL

    IDCAMS FROMKEY/TOKEY support in REPRO MERGECAT is planned to help make it easier to move catalog entries from one catalog to another

    VSAM RLS 64-bit virtual can allow continued growth for applications using VSAM RLS

    DFSMShsm extends TTOC records to support more than 330,000 data sets per volume and support DFSMShsm journal data sets larger than 65,535 tracks

    DFSMSrmm supports data sets larger than 65,535 tracks for the journal, journal backup, and certain temporary data sets

    DFSMSdss exploits Format-1 Channel Command Words (CCWs) so that it can use storage obtained above the 16-MB line during EXCP processing

    Hardware Configuration Definition (HCD) Input Output Definition File (IODF) improvements
