z/OS V1.13 includes several enhancements designed to:
  • Help you get early warning of certain system issues before they become obvious to help you act quickly and decisively with integration between z/OS Predictive Failure Analysis and Runtime Diagnostics functions.
  • Simplify application programming with a new z/OS base component, z/OS Batch Runtime environment, designed to enable COBOL and Java™ to interoperate with DB2® applications while maintaining transactional integrity, thus allowing enhancements to existing COBOL DB2 application suites with Java-based DB2 access.
  • Help you shorten batch windows using JES2 JCL improvements and a new option to free tape volumes more quickly.
  • Improve spool volume management by using new JES2 spool migration function and JES3 dynamic spool add capability.
  • Improve I/O performance between 50% (1.5X) and 150% (2.5X) for many z/OS UNIX™ workload using shared zSeries® File System (zFS) in a Parallel Sysplex®. Applications that use zFS, such as z/OS UNIX System Services and WebSphere® Application Server for z/OS, are expected to benefit.1
  • Improve performance for traditional workloads with IEBCOPY improvements.
  • Provide more options you can use to secure your data with newer, faster, and more scalable encryption and security capabilities incorporated in IBM Tivoli® Directory Server for z/OS (LDAP), RACF®, z/OS System SSL, ICSF, and z/OS PKI Services.

z/OS Management Facility V1.13 offers several enhancements designed to:
  • Clone z/OS images and deploy software more easily and consistently, using a new software deployment task
  • Define new storage volumes to SMS quickly and easily, using a new DASD management task
  • More easily maintain highly secure network connections with an updated z/OSMF-based Configuration Assistant for z/OS Communications Server
  • Create a more unified z/OS experience for system programmers by enabling a new web-enabled ISPF interface from z/OSMF
  • Support easier monitoring of z/OS Capacity Provisioning Manager status, using a new capacity provisioning task
  • Consolidate monitoring for z/OS and Linux™ workload server resources with new, integrated Linux system data gatherers in the updated Resource Monitoring task
  • Improve monitoring and management of incidents, and sending of diagnostic data using the updated Incident Log task
  • Integrate the z/OS experience with the ability to link and launch between z/OSMF applications and between z/OSMF and other browser-accessible applications
  • Deliver a new REST interface designed to enable z/OS and non z/OS systems to submit z/OS jobs, obtain job status, retrieve job output, and more.
