This section describes the pre-installation tasks of the WebSphere business
integration administrator. It contains the following:
Before you, as the WebSphere business integration administrator, can begin
installation of the InterChange Server software, you must ensure that the UNIX
system administrator has completed the initialization tasks in Table 21.
Table 21. Initialization steps for the InterChange Server installation
Initialization task | Information you need to obtain |
---|---|
Verification of software and hardware requirements | None |
Installation of a supported version of the UNIX operating system and any required patches | None |
Creation of the WebSphere business integration administrator account | The name (admin by default) and password for the WebSphere business integration administrator account |
Installer creates a directory for the InterChange Server software in the home directory of the user who is running Installer. The UNIX system administrator should give you the name of the user account in which the InterChange Server software is to be installed. This user account is usually the WebSphere business integration administrator (admin by default). In this case, you log in as the WebSphere business integration administrator and Installer copies the InterChange Server software to a directory called IBM/WebSphereICS in the home directory of the WebSphere business integration administrator. This directory is referred to as the InterChange Server directory.
In the default home directory structure, the InterChange Server directory is:
/home_dir/admin/IBM/WebSphereICS
To prepare for the InterChange Server installation:
If you have access to the system console, consult with the UNIX system administrator to ensure that the system has X Window server software.
If you do not have access to the system console, you can perform a remote installation from a remote system:
The UNIX system administrator can provide you with the account name and password.
If you have access to the CD-ROM drive of the UNIX machine, insert the InterChange Server product CD into this drive.
If you do not have access to the CD-ROM drive, ask the UNIX system administrator to mount the InterChange Server product CD for you.
Before Installer can begin installing InterChange Server software, you must determine where this software is to be installed. Installer creates a directory for the InterChange Server software and copies the software into this directory. By default, the directory is ProductDir; that is, an IBM/WebSphereICS directory in the home directory of the user who is running Installer. During the installation process, you can change this location.
Installer assigns as owner of the directory the user who runs Installer. It also restricts access to the IBM/WebSphereICS directory and its contents such that only the owner has all permissions. Therefore, it is important to have the appropriate user begin the InterChange Server installation process.
The WebSphere business integration administrator should work with the UNIX system administrator to determine the InterChange Server installation location.
IBM recommends that you install the software as the WebSphere business integration administrator (admin by default) to limit access to the software to a single account. If you use the default home directory structure, the location of the InterChange Server software is:
/home_dir/admin/IBM/WebSphereICS
You can choose to have InterChange Server installed as root or another user. For example, you might want to use an individual user account if multiple users are installing the software. For these users, Installer creates an IBM/WebSphereICS directory in the account's home directory.
Any account under which you install the InterChange Server software must be part of the WebSphere MQ group, mqm, and have a name of 8 or fewer characters.
If the InterChange Server installation will be using SNMP, you must associate a port number with the SNMP agent. To reserve the default port number of 1161 for the SNMP agent, make an entry in the /etc/services file:
SNMP 1161/tcp # SNMP agent listener
This port number is chosen as the default because it allows non-root users to start the SNMP agent. If you use a port number lower than 1024 only root will be able to start the SNMP agent.
