Common Information Model (CIM) is a standard data model for describing and accessing systems management data in heterogeneous environments. It allows system administrators to write applications that measure system resources in a network with different operating systems and hardware. To enable z/OS for cross platform management, a subset of resources and metrics of a z/OS system are mapped into the CIM standard data model.

CIM was new in z/OS V1R7. In z/OS V1R9, a new component was added that contains a Java™ programming interface for CIM client applications. In z/OS V1R10, all CIM components were consolidated under one single FMID, HPG7750.

Transport layer security (TLS) encryption is performed for CIM by base element Communications Server. CIM does not implement any of its own encryption algorithms.

Type: base element, exclusive, can be dynamically enabled.

Communications Server supports secure TCP/IP, SNA, and UNIX networking throughout an enterprise. It gives you the ability to connect subsystems and applications to each other, and to connect network devices (such as terminals and printers) to the system.

Communications Server consists of two components: IP Services and SNA Services.

A related optional feature is Communications Server Security Level 3.

For encryption, IP Services uses the SNMPv3 DES 56-bit and IP Sec DES 56-bit algorithms. IP Services also uses the System SSL component of Cryptographic Services for encryption services. SNA Services uses the limited DES algorithm for encryption.

Type: optional feature, exclusive, unpriced, cannot be dynamically enabled.

This feature works in conjunction with the Communications Server base element to provide stronger encryption (greater than 64 bits) than that available without this feature. This feature uses the TDES and AES algorithms for encryption. The actual level of encryption that takes place with this feature installed can be configured to be less than the maximum level enabled by this feature.

This feature is worldwide exportable subject to U.S. export regulations.

Type: base element, exclusive.

Type: optional feature, exclusive, priced, can be dynamically enabled.

DFSMSrmm helps you manage your removable media as one enterprise-wide library across systems that can share DASD. DFSMSrmm also has a client/server function that enables a single enterprise-wide library without the need for shared DASD (c/s is via TCP/IP).

Type: optional feature, exclusive, priced, can be dynamically enabled.

(SMP/E V3R6, 5655-G44)

Type: base element, nonexclusive.

SMP/E is a tool for installing and maintaining software, and for managing the inventory of software that has been installed.

The SMP/E product allows customers who are currently licensed for an earlier level of z/OS to order and install the latest level of SMP/E without having to upgrade their entire operating system. This allows products that run on z/OS to exploit the packaging and installation enhancements of SMP/E without requiring a later level of the operating system. This also allows customers to exploit new electronic delivery and installation technologies in SMP/E sooner. The SMP/E product is available at no additional charge to customers.

The Planning and Migration Assistant (PMA), a component of SMP/E, can help you maintain, plan for, and order new releases of z/OS and other products.
