> Installing the WEM Software
> This chapter provides the step-by-step procedure of installing WEM application using the GUI-based installation wizard and the console-based installation. Additionally it provides instructions that need to be followed before starting the WEM installation so that it completes successfully.
> This chapter includes the following topics:

> • | Before You Begin

> • | Setting the PostgreSQL Database System Environment Configurations

> • | Unpacking the Installation Files

> • | Determining the Best Installation Method

> • | Installing the WEM Software using the GUI-Based Installation Wizard

> • | Installing the WEM Software using the Console-Based Installation Method

> • | Configuring IPMP on WEM Server

> Important: Unless otherwise specified, the information in this chapter applies to both Sun Solaris and Red Hat Enterprise Linux-based (RHEL) WEM systems.
> Before You Begin
> Prior to performing the installation procedure, this section previews each step to ensure that your ready to successfully complete the installation. Detailed installation instructions follow.
> Important: Special rules apply when you are installing redundant High Availability servers using Oracle or Veritas clustering software. Refer to the appendices for more information.
> Step 1 - Verifying Hardware Status
> The first thing that you need to do is to ensure that the WEM server hardware has been provisioned properly for your application. This includes:

> • | Verifying the correct operating system. This can be accomplished by entering the uname -a command.

> • | Verifying that the hard disk has been partitioned properly using the recommendations outlined in the WEM Server Hardware Sizing and Provisioning Guidelines section of the WEM Port and Hardware Information chapter.

> • | Verifying network connectivity through the management LAN.

> Step 2 - Setting the WEM Server's Database Environment Strings
> This step is required to configure how the PostgreSQL database engine processes, stores, and retrieves information contained in the various databases stored using the UNIX file subsystem. Failure to configure these settings may cause data loss and will minimally cause errors in the WEM's operation. Special instructions apply for updating the Postgres database if you are installing redundant High Availability servers using clustering software. Refer to the appendices for more information before you start installation.
> Step 3 - Unpacking the WEM Application Files
> WEM installation files are distributed as a single compressed file. Once the file is obtained, it must be copied to the server and unpacked. It is recommended that you copy the file to a temporary directory on the server.
> Step 4 - Installing the WEM Software
> This step consists of choosing the desired installation method (console-based or the Graphical User Interface (GUI-based) and performing the physical installation onto the WEM server. There are three software components that are installed as part of this procedure. They are:

> • | WEM software

> • | Apache Web Server software

> • | PostgreSQL database engine software

> Important: If you are installing the WEM to upgrade an existing version that is currently installed and running, proceed to Upgrading the WEM Software chapter of this guide. If you are installing redundant High Availability servers using Clustering software, you should also refer to the appendices for special instructions.
> Step 5 - Configuring WEM Client Session Management Parameters
> There are numerous client session management parameters that control how many client sessions may be simultaneously accessed, idle timeout periods, and various other client-related items. This configuration file, which resides on the WEM server, should be modified (if needed) prior to starting the WEM server processes.
> Caution: Failure to perform the WEM server startup procedure in the exact order shown in this document may prevent the application from initializing and working properly.
> Step 6 - Configuring IP Multipathing (IPMP) on WEM Server (Optional)
> IPMP, or IP multipathing, is a facility provided by Solaris® to provide physical interface failure detection and transparent network access failover for a system with multiple interfaces on the same IP link. IPMP also provides load spreading of packets for systems with multiple interfaces.
> For IPMP configuration, refer to the Configuring IPMP on WEM Server section.
> Important: IPMP is a feature supported on Solaris® platforms provided by Oracle. The configuration is documented in the various User Guides from Oracle.
> Setting the PostgreSQL Database System Environment Configurations
> Prior to installing the WEM application onto the WEM server hardware, there are numerous system environment configuration settings that should be configured. While PostgreSQL is installed during the GUI-based installation procedure, these settings must be configured manually.
> Red Hat Enterprise Linux (RHEL) Servers
> In the System Settings Check Panel, ensure that following entries are present in '/etc/sysctl.conf'

> • | kernel.shmmax=536870912

> • | kernel.shmall=2097152

> If one or more entries are missing then abort installation, update '/etc/sysctl.conf', restart the system and re-run installer.
> Solaris Servers
> In Solaris, the user has to edit the /etc/system file.
> Add the following values to the system file in the /etc directory and restart the system before continuing with the installation of the WEM application:
> set msgsys:msginfo_msgmnb=65536
> set msgsys:msginfo_msgtql=1024
> set shmsys:shminfo_shmmax=0x20000000
> set shmsys:shminfo_shmmin=1
> set shmsys:shminfo_shmmni=256
> set shmsys:shminfo_shmseg=256
> set semsys:seminfo_semmap=256
> set semsys:seminfo_semmni=512
> set semsys:seminfo_semmns=512
> set semsys:seminfo_semmsl=32

> Configuring IPMP on WEM Server
> With IPMP, two or more network interface cards (bge0, bge1 etc.) are dedicated for each network to which the host connects. Each interface is assigned a static “test” IP address, which is used to access the operational state of the interface. Each virtual IP address is assigned to an interface, though there may be more interfaces than virtual IP addresses, some of the interfaces being purely for standby purposes. When the failure of an interface is detected its virtual IP addresses are swapped to an operational interface in the group.
> The IPMP load spreading feature increases the machine's bandwidth by spreading the outbound load between all the cards in the same IPMP group.
> Important: IPMP is a feature supported on Sun® Solaris® provided by Sun Microsystems. The configuration is included in Section VI of the System Administration Guide: IP Services from Sun Microsystems. For more information, refer to the Sun documentation
> This section describes following procedures to configured IP Multipathing on WEM server:

> • | Configuring Probe-based IP Multipathing

> • | Configuring Link-based IP Multipathing

> Before proceeding for IPMP configuration here are some terms related to IPMP configuration:

> • | Multipath Interface Group: This the name given to the group of network devices in a multipath configuration.

> • | Test Addresses: These are IP addresses assigned to each board/interface of the multipath group, they do not move but should not be used for connections in or out of the host.

> • | Multipath/float Address - This is the IP address allocated to a Multipath Interface Group that is shared between all devices in the group (either by load sharing or active standby).

> Configuring Probe-based IP Multipathing
> Configuration procedure given here assumes that:

> • | WEM Server Host name is hostname

> • | NIC_1 and NIC_2 are the network interface devices; i.e. bge0, bge1 etc.

> • | Using network device NIC_2 as active and NIC_1 as the Standby

> • | Multipath Interface Group name is multipath_grp

> • | Multipath IP address is <multipath_IP_address>

> • | Test IP address for <NIC_1> interface in <test_IP_address_NIC_1>

> • | Test IP address for <NIC_2> interface in <test_IP_address_NIC_2>

> Step 1 | Ensure that the MAC addresses on the host are unique by setting the local-mac-address parameter to true by running following command as root user:

> eeprom local-mac-address?=true

> Step 2 | Create an NIC_1 for the Standby network device with the following entry:

> <hostname>-<NIC_1> netmask <netmask> broadcast+group <multipath_grp> deprecated -failover standby up
> <hostname> is name of the Host and <NIC_1> is the network device to be set as Standby.
> <multipath_grp> is Multipath Interface Group name given to the group of network devices in a multipath configuration.
> <netmask> is the sub-netmask used by network.

> Step 3 | Create an NIC_2 for the active network device with the following entry:

> <hostname>-<NIC_2> netmask 255.255.255.0 broadcast+group <multipath_grp> deprecated -failover up addif <hostname>-active netmask 255.255.255.0 broadcast+failover up
> <hostname> is name of the Host and <NIC_2> is the network device to be set as Active.
> <multipath_grp> is Multipath Interface Group name given to the group of network devices in a multipath configuration.

> Step 4 | Edit the /etc/hosts file using “vi editor” and add the following three entries:

> <multipath_IP_address> <hostname>-active
> <test_IP_address_NIC_1> <hostname>-NIC_1
> <test_IP_address_NIC_2> <hostname>-NIC_2
> multipath_IP_address is the IP address allocated to a Multipath Interface Group that is shared between all devices in the group (either by load sharing or Active-Standby).
> test_IP_address_NIC_1 is the IP addresses assigned to <NIC_1> interface of the multipath group, they do not move but should not be used for connections in or out of the host.
> test_IP_address_NIC_2 is the IP addresses assigned to <NIC_2> interface of the multipath group, they do not move but should not be used for connections in or out of the host.

> Step 5 | Restart the host by supplying following command:

> shutdown -i 6 -g 0 -y
> Configuring Link-based IP Multipathing
> Configuration procedure provided here assumes that:

> • | WEM Server Host name is <hostname>

> • | <NIC_1> and <NIC_2> are the network interface devices; i.e. bge0, bge1 etc.

> • | Using network device <NIC_1> as active and <NIC_2> as the standby

> • | Multipath Interface Group name is <multipath_grp>

> • | Multipath IP address is <multipath_IP_address>

> • | Test IP address for <NIC_1> interface in <test_IP_address_NIC_1>

> • | Test IP address for <NIC_2> interface in <test_IP_address_NIC_2>

> • | <my_address> is associated with Multipath IP address <multipath_IP_address> in the /etc/hosts file

> Step 1 | Ensure that the MAC addresses on the host are unique by setting the local-mac-address parameter to true by running following command as root user:

> eeprom local-mac-address?=true

> Step 2 | Create an NIC_1 for the Active network device with the following entry:

> <my_address> netmask + broadcast + group <multipath_grp> up
> <my_address> is associated with Multipath IP address <multipath_IP_address> in the /etc/host file.
> <multipath_grp> is Multipath Interface Group name given to the group of network devices in a multipath configuration.

> Step 3 | Create an NIC_2 for the Standby network device with the following entry:

> group <multipath_grp> up

> Step 4 | Restart the host by supplying following command:

> shutdown -i 6 -g 0 -y
