This section includes information on setting up the operating system for WebSphere Portal and Cloudscape. Other components might require additional steps.

Before you install WebSphere Portal, review the following information to ensure that the machine is ready for installation.

 

Checking the network setup

Proper network configuration is essential when installing WebSphere Portal. Verify the following network setup requirements before installation:

  • Fully qualified host.name. WebSphere Portal also requires the use of a fully qualified host.name, which is typically the host.name of the server, along with its fully qualified domain name (FQDN). To be sure that this is configured correctly, we can check with a simple ping before you start installation. For example, you could enter the following command at a command prompt: 

        ping yourserver.yourcompany.com

 

Prepare the installation directory tree

Before installing WebSphere Portal on Solaris ensure that the installation UserID has write access to all directories in the installation target directory tree.

 

Prepare Solaris kernel settings before installing

Several Solaris kernel values are typically too small for the messaging requirements of WebSphere Portal. Starting the internal JMS server or client with insufficient kernel resources produces a First Failure Support Technology (FFST) file in the /var/errors directory. Before installing WebSphere Portal, review the machine's configuration.

The values described here are a starting point for messaging in WebSphere Portal only. If the system has other applications installed, the value requirements will likely be different. For example, if values that are already set are higher than the settings listed here, the values should not be lowered. Be sure to check the requirements made on /etc/system by other already-installed applications before altering existing values.

To review the configuration, type the following command: sysdef -i

The kernel values are set in the /etc/system file. The values shown here are the minimum values that must be specified before installing WebSphere Portal.

Parameter Minimum Value
set shmsys:shminfo_shmmax = 4294967295
set shmsys:shminfo_shmseg = 1024
set shmsys:shminfo_shmmni = 1024
set semsys:seminfo_semaem = 16384
set semsys:seminfo_semmni = 1024
set semsys:seminfo_semmap = 1026
set semsys:seminfo_semmns = 16384
set semsys:seminfo_semmsl = 100
set semsys:seminfo_semopm = 100
set semsys:seminfo_semmnu = 2048
set semsys:seminfo_semume = 256
set msgsys:msginfo_msgmap = 1026
set msgsys:msginfo_msgmax = 65535
set rlim_fd_cur= 1024

After updating the /etc/system file with these changes reboot the operating system in order for the updates to be applied.
