User accounts

In a complex application integration environment, many systems and software configurations require user accounts that assign specific permissions. Before installing InterChange Server, plan for the user accounts that you will need. Table 10 lists the user accounts required.

Table 10. User accounts

Account type Description
UNIX system administrator (root) The UNIX system administrator creates user accounts and installs most of the third-party software.
WebSphere business integration administrator (admin by default) The WebSphere business integration administrator installs and configures the WebSphere business integration system.
Database administrator (DBA)
The DBA creates the databases, data sources, and InterChange Server DBMS access account that the ICS system uses.
InterChange Server RDBMS access account (by default, wicsadmin

for DB2 and Oracle databases; ics for Microsoft SQL Server database)

InterChange Server uses this login account to access the required databases.
mqm user account The mqm user account is required to run WebSphere MQ.

Several of the installation steps require root privilege; that is, they must be performed by the root user. The root user account is the UNIX system administration account with the highest privilege levels. To become root requires the password for the root user account. Therefore, the password to this account is usually tightly controlled by the UNIX system administrator.

This System Installation Guide for Unix assumes that the root password is not available to the WebSphere business integration administrator (the person who installs the WebSphere business integration system). Pre-installation administration tasks, describes the tasks that must be performed by someone with root privileges (usually the UNIX system administrator). The rest of the installation procedures, described throughout this document, do not require root privileges.
