      Release 12.2
      The
      View
      Release 12.2 DRAS base and agent code is supplied with the
      View
      Release install as SYSMODs CBY3C20 and CBY3C22.
      The
      View
      Release 12.2 DRAS agent can access
      View
      supported databases Release 12.2, Release 12.1, and Version 12.0.
      However, for compatibility, if you versioned your
      View
      database to the most recent version, verify that your
      DRAS
      task uses the most recent libraries.
  • Client Viewer Applications:
    • Web Viewer

  • TCP/IP Communications
    • IBM TCP/IP
Common Components and Services
Prerequisites
DRAS
runs in a z/OS environment and uses common functions provided with
Common Components and Services
. If the following services are not already installed on your system, they must be installed before you proceed with this installation.
The following services are required for cooperative viewing with
DRAS
:
  • CAIENF
  • CAICCI
  • CAICCI for TCP/IP
Common Components and Services
must be installed or maintained at the gen level indicated on the cover letter for the product.
For more information including installing, configuring, and using the common services, see "Getting Started" in the
Common Components and Services
documentation.
CAIENF
DRAS
uses CAIENF (Event Notification Facility) services. CAIENF is an operating system interface component that provides a simple approach for
Broadcom
products to obtain data from an MVS system by interfacing to any
Broadcom
z/OS applications, thus exploiting technologies such as relational database architectures for the benefit of the entire product line.
The level of integration is improved by enabling operating systems and
Broadcom
software
-
generated event information to be driven through a standard interface, simplifying multiple product-to-product interfaces, and associated necessary maintenance.
Be aware of the following:
  • CAIENF must be installed into an APF authorized library.
    Linklist is recommended although it is not required.
  • CAIENF runs as a started task within its own address space.
    A database must be allocated and initialized for CAIENF to use. For more information about space requirements, see the
    Common Components and Services
    documentation.
DRAS
does not use the CAIENF/CICS component.
CAICCI
CAICCI (Common Communications Interface) provides
Broadcom
enterprise applications with a wealth of capabilities, including common communications, cooperative processing, and database server facilities, and distributed database management. Full support for all forms of distributed processing helps ensure the highest degree of flexibility for the enterprise.
DRAS
uses the CAICCI service to provide communication between client applications and the servers. CAICCI is a facility that allows
Broadcom
products to communicate with other applications in a simple, straightforward manner.
CAICCI builds a layer on top of today's communication and network software so that an application can be isolated from the specifics of its environment.
Be aware of the following:
  • CAICCI must be installed into an APF (Authorized Program Facility) authorized library. The library used must be the same as the one used for CAIENF component installation.
  • CAICCI runs as a CAIENF subtask within CAIENFs address space. CAICCI uses the same database as the one allocated and initialized for CAIENF to use. CAICCI requires that an update is made to the CAIENF database. For more information, see
    Common Components and Services
    documentation.
CAICCI for TCP/IP
CAICCI provides robust TCP/IP support, and this protocol can be used to connect a wide variety of platforms and applications. Mainframes and PCs can be inter-connected, using TCP/IP.
Be aware of the following:
  • If you are using TCP/IP as your communications protocol, a mainframe TCP/IP product must be installed in addition to the base CAICCI component. The IBM TCP/IP products are supported for z/OS.
  • CAICCI utilizes TCP/IP using one or more separate server address spaces to coordinate TCP/IP processing for CAICCI. The CCITCP server task supports mainframe-to-PC connections using TCP/IP, and is required for
    DRAS
    .
  • Use the appropriate client/server protocol parameter, depending on your vendor for TCP/IP or C runtime, as described in the
    Common Components and Services
    documentation.
CAIRIM
CAIRIM (CAI Resource Initialization Manager) is the common driver for a collection of dynamic initialization routines. These initialization routines eliminate the need for user SVCs, SMF exits, subsystems, and other installation requirements that you commonly encounter when you install systems software. CAIRIM prepares the operating system for
Broadcom
products and components, and then executes them.
The following list contains some of the tasks CAIRIM performs:
  • Obtains SMF data
  • Verifies proper software installation
  • Installs MVS interfaces
  • Automatically starts
    Broadcom
    products and the products of other vendors
  • Properly times and sets the order of the initialization
DRAS
requires CAIRIM to run the required
LMP
if Web Viewer Version 12.0 or higher (any platform) is used.
LMP
The License Management Program (
LMP
) is a standardized automated approach to the tracking of licensed software that uses common real-time enforcement software to validate the user's configuration.
LMP
reports on activities related to the license, usage, and financial activity of program solutions.
LMP
features include:
  • A common key data set that can be shared among many CPUs
  • The use of "check digits" to detect errors in transcribing key information
  • Execution keys that can be entered without affecting any
    Broadcom
    software solution already running
  • No special maintenance requirements
Resource Requirements
Depending on the mainframe repository you intend to use, see the
View
or
Dispatch
installation documentation for further information.
