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.

5.1.11Enabling 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.
