132 Tivoli Business Systems Manager Version 2.1: End-to-End Business Impact Management
Systems Manager: Administrator’s Guide
, GC32-0799. They need advanced
knowledge about how IBM Tivoli Business Systems Manager works and what
is required for maintaining it. Depending on the implementation scope,
administrators may have experience as a mainframe system programmer,
Tivoli administrator, or Windows/LAN administrator. The administrator team’s
skill base should include at least these three backgrounds.
5.3 Hardware specifications
Capacity and specifications for the IBM Tivoli Business Systems Manager’s
servers must be decided before implementation can begin. This requires careful
estimation and planning for the server’s expected workload.
The implementation team should consider:
? Implementation type: enterprise (mainframe and distributed) or only
distributed
? Number of events
? Number of objects to be managed
? Number of operators
? Number of Business System Views
? Activation of certain functions
When planning for the number of machines that your system will require, include
the following considerations:
? Database server: This has to be the machine with fastest processors and
most memory.
? Propagation server and console server: For a mainframe and distributed
environment, separate machines are recommended for the two servers. In a
distributed-only environment, they can be combined on the same machine.
? Event server and SNA server: These two machines are recommended for
SNA connectivity to the mainframe, while for IP connectivity to the mainframe,
you can have only an event server, or you can split the event server’s
receiving and sending functions between two servers.
? History server: This is recommended in the enterprise environment, while it is
optional for the distributed environment.
? Testing and quality assurance servers: These servers are needed for testing
instrumentation and feeds for new resources before they are released for
production. For a standard enterprise environment, this can be implemented
over three servers.
