5.1.10 Setting shared memory
This section details how to set a minimum shared memory value in Linux. For
Linux systems, you must set a minimum shared memory value for the system
prior to using the Tivoli middleware installer. To set the minimum shared memory
value, complete the following steps:
From a command line, type sysctl -w kernel.shmmax and determine if the
value is less than 268435456 bytes (256Mb).
If you need to increase the value, from a command line, type sysctl -w
kernel.shmmax=268435456.
Update the value in /etc/sysctl.conf.
5.1.11 Enabling remote configuration
If you plan to take advantage of the Maximo Asset Management Essentials
installation program feature that automates the configuration of Maximo Asset
Management Essentials middleware, you must enable a Remote Execution and
Access (RXA) service for each system on which you intend to install Maximo
Asset Management Essentials middleware. RXA requires that the target system
enable at least one of the protocols supported by RXA, which include rsh, rexec,
SSH and Windows SMB. Before you start the Maximo Asset Management
Essentials installation program, ensure that one of these protocols is running and
will accept remote logins using a user name and password configured on the
target machine
If the remote system is a Windows machine, you must configure RXA to work
over SMB. For Windows machines, you cannot use Cygwin ssh. If Cygwin is
present on the Windows machine, the installation will fail. Default installations of
AIX systems might not include a suitable protocol and will need to have RXA
compatible protocols enabled. RXA does not support accessing network drives
on the local or remote system.
5.2 Installation flowchart
The flowchart shown in Figure 5-1 on page 43 defines the installation flow
required to successfully install IBM Tivoli Asset Management for IT. There is a
Launchpad utility that will lead you through the installation of various components
of the product. In general, there are three phases of the installation:
