Installation Best Practices

Review the installation best practices for the Broadcom mainframe software products.
Before you begin the installation process, review the following best practices:
Manage Security and Integrity Fixes
Broadcom
offers Security and Integrity maintenance that addresses a security or integrity exposure. We categorize this maintenance as a “SECINT” or “Security or Integrity” fix type using our mainframe software packaging system. With each Security or Integrity Fix,
Broadcom
also offers access to Security Advisory articles that include additional details and context about a security or integrity exposure. Each article details the CVSS score, the CVSS Vector String, the affected components, and the CVE numbers, if applicable. This central resource offers self-service information and an email subscription service to be alerted about new security advisories.
Business Value:
This maintenance lets you quickly identify and apply security or integrity maintenance. The proactive notifications let you address security issues immediately.

Configure
SMP/E Internet Service Retrieval
for Product Maintenance
Configure
SMP/E Internet Service Retrieval
to eliminate the need to download maintenance manually. This service uses the IBM SMP/E RECEIVE ORDER command to acquire
Broadcom
mainframe product maintenance. This service enables you to acquire maintenance on demand or to schedule an SMP/E job to run as needed.
If you are an existing
CSM
customer, you can also use this service to download maintenance and dramatically reduce the time that is required to download PTFs.
Business Value:
SMP/E Internet Service Retrieval
can reduce hours of maintenance time to just minutes, making your system programmers more productive and allowing them to focus on higher value tasks.
SMP/E Internet Service Retrieval
:
  • Eliminates time-consuming fix searches and the need to select maintenance manually from the
    Broadcom Support
    portal
  • Automates delivery of
    Broadcom
    maintenance directly to your mainframe
  • Fulfills orders based on the status of your SMP/E environments
  • Enables scheduling of maintenance downloads
  • Facilitates an easier installation of Recommended and Preventive service

Implement a Proactive Preventive Maintenance Strategy
Use
CARS
to implement a proactive preventive maintenance strategy.
CARS
is patterned after the IBM preventive maintenance model, Recommended Service Upgrade (RSU). With
CARS
, you can install preventive maintenance for most
Broadcom
z/OS based products consistently on a schedule that you select (monthly, quarterly, annually). You can follow the same schedule that you use to apply IBM maintenance, or you can implement a schedule for
Broadcom
products only.
Business Value:
Keeping your products current with maintenance helps your team remain productive and minimizes errors while safely protecting your systems. If you do not install preventive maintenance regularly, you risk encountering known problems for which we have published and tested fixes. Early notification about the potential need to apply a required fix helps avoid unscheduled downtime and assists you in proactively maintaining your software.

Sign up for Hiper Notifications
Sign up for HIPER notifications for all
Broadcom
products on the
Broadcom Support
website so that you receive notification of potential problems for your products as soon as possible. Subscribe to HIPER and other product notifications like security advisories within the
Broadcom Support
portal. Signin and select

.
Business Value:
Early notification about the potential need to apply a required fix helps avoid unscheduled downtime and assists you in proactively maintaining your software.
Apply IBM Maintenance
Review the current list of IBM APARs for z/OS, especially related to hipers. Apply the APARs that are appropriate to your environment.
Business Value:
Missing APARs can affect the operation or performance of your product.
Review Health Check Messages
The
are now integrated with the IBM Health Checker for z/OS through the
CA Health Checker
to verify that deployed software follows our best practices. Review the health check generated messages from the health checks to identify potential problems automatically.
Business Value:
The health checks continually monitor the system and software to provide feedback on whether the software remains configured optimally.
Additional Considerations:
When one or more subtasks contain errors, the health check generates an exception error that assigns a severity level to the exception and lists the abending tasks. This message provides an explanation, system action, operator response, system programmer response, problem determination, source, and reference documentation. Other messages are generated to help diagnose and correct the condition.
More Information:
For more information about product-specific health checks, see the product documentation.
Optimize
SYSVIEW for Db2
Installation Setup
We recommend the following activities regarding
SYSVIEW for Db2
installation setup:
For detailed information about these tasks, see Review
SYSVIEW for Db2
Configuration Best Practices.
  • Start data collector and PC tasks automatically at IPL
  • Enable the appropriate security authorizations
  • Adjust dispatching priority to avoid lost trace data
  • Create an OBID table translation file
  • Allocate adequate trace collection buffers
  • Use one exception data set for all data collector tasks
  • Enable data sharing when monitoring data sharing subsystems
  • Adjust the REGION size
  • Avoid data collector overhead
