  • CICS TS for z/VSE V2.1 fulfills further customer requirements, such as:
    • Cipher suites AES 128 and AES 256 for CICS web support to allow for enhanced Secure Sockets Layer (SSL) connectivity.
    • Millisecond option added to various EXEC CICS commands.
    • OSLEVEL option added to EXEC CICS INQUIRE SYSTEM command.

IBM TCP/IP for z/VSE V2.1 for enhanced security

  • IBM TCP/IP for z/VSE 2.1 is a new level set that integrates all prior maintenance.
  • This new version is designed to add a white list firewall feature to provide a more secure environment.
  • In addition it will contain internal processing improvements to provide a more stable and efficient stack as well as many functional enhancements based upon customer requests. These are:
    • External partition socket requests will be using cross memory services to improve efficiency.
    • New utilities will be provided to externalize applications for automation and TN3270 services.
    • The TLS/SSL cryptography will be enhanced to support RFC5746. This will allow the usage of TLS extensions to prevent the handshake renegotiation security exposure.

IBM IPv6/VSE V1.2 for enhanced security, and increased network availability

These are some of the highlights planned for the new IPv6/VSE release:

  • Basic firewall support:
    • The basic firewall security facility examines IPv4 packets and IPv6 Ethernet frames for basic types of information. The source IP address, packet protocol, TCP or UDP port numbers, and ICMP message type and code can be verified and processing accepted or denied.
  • Automatic OSA Express® device failover using HOTSWAP devices for high availability:
    • IBM IPv6/VSE 1.2 will allow users to automatically recover from OSA Express device failures by utilizing a backup HOTSWAP device. This can dramatically reduce the duration of network interruptions.
  • Improved stack CPU optimization:
    • This can result in reduced CPU utilization by the stack partitions and thus may improve network throughput.
  • Improved SSL support including TLS1.2 and DH/ECC sockets:
    • IBM IPv6/VSE V1.2 will support the latest updates in the IBM OpenSSL port, including support for TLSV1.2 and DH/ECC SSL socket, and all the latest security fixes.
    • The SSL Proxy and Automatic TLS facilities will be improved to support establishing up to 16 SSL sockets concurrently. This can dramatically improve performance for applications that establish multiple connections to z/VSE including TN3270(E), CICS, and web services applications.
  • Virtual IP address support using virtual network interfaces:
    • IBM IPv6/VSE V1.2 will support having multiple IP addresses defined for a single network interface through the use of virtual network interfaces. The virtual network interfaces share a single OSA Express device.

MQ Client Trigger Monitor

IBM WebSphere MQ for z/VSE V3.0 will be withdrawn from service, effective September 30, 2015. However, the IBM WebSphere MQ Client for VSE will continue to be available.

Using the WebSphere MQ Client for VSE, a WebSphere MQ application can interact by means of the MQ API with one or more WebSphere MQ servers on any supported platform and connect to their queue managers. Therefore, the MQ Client for VSE may be an alternative for clients currently using the WebSphere MQ for z/VSE server.

Unlike the MQ Client packages that are available for Linux™, z/OS, and other platforms, the WebSphere MQ Client for VSE does not contain a trigger monitor. Triggering is a must-have feature to process asynchronous messages. It allows the system to start (trigger) an application when a message arrives on a queue of a WebSphere MQ server.

The MQ Client Trigger Monitor closes this gap. It triggers a z/VSE CICS application when messages arrive on a queue of a Websphere MQ Server. Adding trigger functionality for the WebSphere MQ Client for VSE fulfills customer requirements and may enable clients to use the WebSphere MQ client instead of the WebSphere MQ Server on z/VSE.

Networking enhancements

Configurable output buffers for HiperSockets™ and OSA Express devices for improved TCP/IP throughput:

  • Best performance can be achieved when data are always delivered successfully without the need of resending. z/VSE uses a default of eight QDIO (Queued Direct I/O) output buffers. This might not always be sufficient. z/VSE V6.1 will allow users to configure up to 64 QDIO output buffers for HiperSockets (CHPID type IQD) and OSA-Express (CHPID types OSD and OSX) devices. To ease the configuration skeleton SKOSACFG in ICCF library 59 can be used. Additional QDIO output buffers might require users to increase the size of the TCP/IP partition.

z/VSE V6.1 and CICS TS for z/VSE V2.1 will fulfill the statements of direction in Software Announcement ZP14-0094, dated April 07, 2014.

Statement of good security practices
Bottom rule

IT system security involves protecting systems and information through prevention, detection, and response to improper access from within and outside your enterprise. Improper access can result in information being altered, destroyed, or misappropriated or can result in misuse of your systems to attack others. Without a comprehensive approach to security, no IT system or product should be considered completely secure and no single product or security measure can be completely effective in preventing improper access. IBM systems and products are designed to be part of a comprehensive security approach, which will necessarily involve additional operational procedures, and may require other systems, products, or services to be most effective. IBM does not warrant that systems and products are immune from the malicious or illegal conduct of any party.
